Nearly half of Earth's population lives in the tropics, and development stresses can potentially harm soil resources, water quality, and water supply and in addition increase landslide and flood hazards. Owing to Puerto Rico's steep topography, low water storage capacity, and dependence on trade-wind precipitation, the island's people, ecosystems, and water supply are vulnerable to extreme weather such as hurricanes, floods, and droughts. Eastern Puerto Rico offers a natural laboratory for separating geologic and land-cover influences from regional- and global-scale influences because of its various bedrock types and the changing land cover surrounding intact, mature forest of the Luquillo Experimental Forest. Accordingly, a multiyear assessment of hydrological and biogeochemical processes was designed to develop an understanding of the effects of these differences on local climate, streamflow, water quality, and ecosystems, and to form the basis for a long-term and event-based program of climate and hydrologic monitoring. Because infrequent, large storms play a major role in this landscape, we focused on high-runoff events, sampling 263 storms, including all major hurricanes from 1991 through 2005. The largest storms have profound geomorphic consequences, such as landslides, debris flows, deep gullying on deforested lands, excavation and suspension of sediment in stream channels, and delivery of a substantial fraction of annual stream sediment load. Large storms sometimes entrain ocean foam and spray causing high concentrations of seasalt-derived constituents in stream waters during the storm. Past deforestation and agricultural activities in the Cayagu&aacute;s and Can&oacute;vanas watersheds accelerated erosion and soil loss, and this material continues to be remobilized during large storms. Nearly 5,000 routine and event samples were analyzed for parameters that allow determination of denudation rates based on suspended and dissolved loads; 860 of these samples were analyzed for a comprehensive suite of chemical constituents. The rivers studied are generally similar in water-quality characteristics, and windward or leeward aspect appears to exert a stronger influence on water quality than geology or land cover. Of samples analyzed for comprehensive chemistry and for sediment, 543 were collected at runoff rates greater than 1 millimeter per hour, 256 at rates exceeding 10 millimeters per hour, and 3 at rates exceeding 90 millimeters per hour. Streams have rarely been sampled during events with such high runoff rates. Rates of physical and chemical weathering are especially high, and physical denudation rates, forested watersheds included, are considerably greater than is expected for a steady-state system. The elevated physical erosion drives an increased particulate organic carbon flux, one that is large, important to the carbon cycle, and sustainable, because soil-carbon regeneration is rapid. The 15-year Water, Energy, and Biogeochemical Budget dataset, which includes discharge, field parameters, suspended sediment, major cations and anions, and nutrients, is available from the U.S. Geological Survey's National Water Information System (http://waterdata.usgs.gov/nwis). The dataset provides a baseline for characterizing future environmental change and will improve our understanding of the interdependencies of land, water, and biological resources and their responses to changes in climate and land use. Because eastern Puerto Rico resembles many tropical regions in terms of geology and patterns of development, implications from this study are transferable to other tropical regions facing deforestation, rapid land-use change, and climate change.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/pp1789","usgsCitation":"Murphy, S.F., Stallard, R.F., Contributions by Buss, H.L., Gould, W.A., Larsen, M.C., Liu, Z., Martinuzzi, S., Pares-Ramos, I., White, A.F., and Zou, X., 2012, Water quality and landscape processes of four watersheds in eastern Puerto Rico: U.S. Geological Survey Professional Paper 1789, viii, 292 p.; Appendices; col. ill.; maps (col.), https://doi.org/10.3133/pp1789.","productDescription":"viii, 292 p.; Appendices; col. ill.; maps (col.)","startPage":"i","endPage":"292","numberOfPages":"304","additionalOnlineFiles":"N","costCenters":[{"id":434,"text":"National Research Program","active":false,"usgs":true}],"links":[{"id":259252,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1789/PP1789.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":259265,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/pp_1789.gif"},{"id":259251,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/pp/1789/","linkFileType":{"id":5,"text":"html"}}],"country":"Puerto Rico","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc87ce4b08c986b32c95f","contributors":{"authors":[{"text":"Murphy, Sheila F. 0000-0002-5481-3635 sfmurphy@usgs.gov","orcid":"https://orcid.org/0000-0002-5481-3635","contributorId":1854,"corporation":false,"usgs":true,"family":"Murphy","given":"Sheila","email":"sfmurphy@usgs.gov","middleInitial":"F.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":465894,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stallard, Robert F. 0000-0001-8209-7608 stallard@usgs.gov","orcid":"https://orcid.org/0000-0001-8209-7608","contributorId":1924,"corporation":false,"usgs":true,"family":"Stallard","given":"Robert","email":"stallard@usgs.gov","middleInitial":"F.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":465895,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Contributions by Buss, Heather L.","contributorId":21830,"corporation":false,"usgs":true,"family":"Contributions by Buss","given":"Heather","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":465898,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gould, William A.","contributorId":103535,"corporation":false,"usgs":true,"family":"Gould","given":"William","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":465902,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Larsen, Matthew C. mclarsen@usgs.gov","contributorId":1568,"corporation":false,"usgs":true,"family":"Larsen","given":"Matthew","email":"mclarsen@usgs.gov","middleInitial":"C.","affiliations":[],"preferred":true,"id":465893,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Liu, Zhigang","contributorId":89015,"corporation":false,"usgs":true,"family":"Liu","given":"Zhigang","affiliations":[],"preferred":false,"id":465900,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Martinuzzi, Sebastian","contributorId":17491,"corporation":false,"usgs":true,"family":"Martinuzzi","given":"Sebastian","affiliations":[],"preferred":false,"id":465897,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Pares-Ramos, Isabel K.","contributorId":98184,"corporation":false,"usgs":true,"family":"Pares-Ramos","given":"Isabel K.","affiliations":[],"preferred":false,"id":465901,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"White, Arthur F. afwhite@usgs.gov","contributorId":3718,"corporation":false,"usgs":true,"family":"White","given":"Arthur","email":"afwhite@usgs.gov","middleInitial":"F.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":465896,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Zou, Xiaoming","contributorId":56521,"corporation":false,"usgs":true,"family":"Zou","given":"Xiaoming","email":"","affiliations":[],"preferred":false,"id":465899,"contributorType":{"id":1,"text":"Authors"},"rank":12}]}}

To evaluate patterns in mussel assemblages in the Upper Mississippi River (UMR), data from systematic surveys of mussels conducted in three large reaches (Navigation Pools 5, 6, and 18) from 2005&ndash;2007 were analysed. 2. Nonmetric multi-dimensional scaling analyses and permutation tests indicated that assemblages differed among reaches. The mussel assemblage in Pool 18 was substantially different from the assemblage in Pool 5 and moderately different from the assemblage in Pool 6, whereas assemblages in Pools 5 and 6 were similar. Assemblages in broadly defined, flowing aquatic habitats did not substantially differ. 3. The dissimilarity of Pool 18 was primarily the result of Pool 18 having higher abundances of three Quadrula species (Q. quadrula, Q. pustulosa, and Q. nodulata), and lower abundances of Amblema plicata and Fusconaia flava. 4. Rarefaction analyses showed that species richness and species density were higher in Pool 18 compared with the other two pools. 5. Large-scale patterns in mussel assemblages may be related to other longitudinal trends in the system including geomorphology, water quality, and abundances of fish species that serve as hosts for glochidial larvae. 6. The results suggest that management goals and actions in the UMR may need to account for important differences in mussel assemblages that occur among reaches.","language":"English","publisher":"Wiley","doi":"10.1002/aqc.2255","usgsCitation":"Zigler, S.J., Newton, T., Davis, M., and Rogala, J.T., 2012, Patterns in species richness and assemblage structure of native mussels in the Upper Mississippi River: Aquatic Conservation: Marine and Freshwater Ecosystems, v. 22, no. 5, p. 577-587, https://doi.org/10.1002/aqc.2255.","productDescription":"11 p.","startPage":"577","endPage":"587","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":381726,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Illinois, Iowa, Minnesota, Wisconsin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -97.646484375,\n              48.922499263758255\n            ],\n            [\n              -96.85546875,\n              45.213003555993964\n            ],\n            [\n              -96.6796875,\n              43.26120612479979\n            ],\n            [\n              -95.537109375,\n              40.38002840251183\n            ],\n            [\n              -91.669921875,\n              40.58058466412761\n            ],\n            [\n              -89.912109375,\n              38.13455657705411\n            ],\n            [\n              -89.296875,\n              37.020098201368114\n            ],\n            [\n              -87.802734375,\n              38.20365531807149\n            ],\n            [\n              -87.5390625,\n              41.50857729743935\n            ],\n            [\n              -87.36328125,\n              45.1510532655634\n            ],\n            [\n              -89.736328125,\n              46.195042108660154\n            ],\n            [\n              -90.791015625,\n              46.86019101567027\n            ],\n            [\n              -89.736328125,\n              48.3416461723746\n            ],\n            [\n              -95.2734375,\n              49.03786794532644\n            ],\n            [\n              -97.646484375,\n              48.922499263758255\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"22","issue":"5","noUsgsAuthors":false,"publicationDate":"2012-05-29","publicationStatus":"PW","scienceBaseUri":"505a75bfe4b0c8380cd77d07","contributors":{"authors":[{"text":"Zigler, Steven J. 0000-0002-4153-0652 szigler@usgs.gov","orcid":"https://orcid.org/0000-0002-4153-0652","contributorId":2410,"corporation":false,"usgs":true,"family":"Zigler","given":"Steven","email":"szigler@usgs.gov","middleInitial":"J.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":464710,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Newton, Teresa J. 0000-0001-9351-5852","orcid":"https://orcid.org/0000-0001-9351-5852","contributorId":78696,"corporation":false,"usgs":true,"family":"Newton","given":"Teresa J.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":464713,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Davis, Mike","contributorId":50284,"corporation":false,"usgs":true,"family":"Davis","given":"Mike","affiliations":[],"preferred":false,"id":464712,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rogala, James T. 0000-0002-1954-4097 jrogala@usgs.gov","orcid":"https://orcid.org/0000-0002-1954-4097","contributorId":2651,"corporation":false,"usgs":true,"family":"Rogala","given":"James","email":"jrogala@usgs.gov","middleInitial":"T.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":464711,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The synthesis presented herein documents how current and future land change may alter environment processes and in turn, how those conditions may affect both land cover and land use by specifically investigating, * The primary contemporary trends in land use and land cover, * The land-use and land-cover sectors and regions which are most affected by weather and climate variability,* How land-use practices are adapting to climate change, * How land-use and land-cover patterns and conditions are affecting weather and climate, and * The key elements of an ongoing Land Resources assessment. These findings present information that can be used to better assess land change and climate interactions in order to better assess land management and adaptation strategies for future environmental change and to assist in the development of a framework for an ongoing national assessment.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20121155","usgsCitation":"Loveland, T., Mahmood, R., Patel-Weynand, T., Karstensen, K., Beckendorf, K., Bliss, N., and Carleton, A., 2012, National climate assessment technical report on the impacts of climate and land use and land cover change: U.S. Geological Survey Open-File Report 2012-1155, vi, 86 p.; col. ill.; maps (col.), https://doi.org/10.3133/ofr20121155.","productDescription":"vi, 86 p.; col. ill.; maps (col.)","startPage":"i","endPage":"86","numberOfPages":"92","onlineOnly":"Y","additionalOnlineFiles":"N","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":259275,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2012_1155.gif"},{"id":259253,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2012/1155/","linkFileType":{"id":5,"text":"html"}},{"id":259254,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2012/1155/of2012-1155.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6263e4b0c8380cd71ebd","contributors":{"authors":[{"text":"Loveland, Thomas 0000-0003-3114-6646","orcid":"https://orcid.org/0000-0003-3114-6646","contributorId":103924,"corporation":false,"usgs":true,"family":"Loveland","given":"Thomas","affiliations":[],"preferred":false,"id":465909,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mahmood, Rezaul","contributorId":34376,"corporation":false,"usgs":true,"family":"Mahmood","given":"Rezaul","affiliations":[],"preferred":false,"id":465906,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Patel-Weynand, Toral","contributorId":26566,"corporation":false,"usgs":true,"family":"Patel-Weynand","given":"Toral","email":"","affiliations":[],"preferred":false,"id":465904,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Karstensen, Krista","contributorId":97758,"corporation":false,"usgs":true,"family":"Karstensen","given":"Krista","affiliations":[],"preferred":false,"id":465908,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Beckendorf, Kari","contributorId":23379,"corporation":false,"usgs":true,"family":"Beckendorf","given":"Kari","email":"","affiliations":[],"preferred":false,"id":465903,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Bliss, Norman 0000-0003-2409-5211","orcid":"https://orcid.org/0000-0003-2409-5211","contributorId":32485,"corporation":false,"usgs":true,"family":"Bliss","given":"Norman","affiliations":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"preferred":false,"id":465905,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Carleton, Andrew","contributorId":58510,"corporation":false,"usgs":true,"family":"Carleton","given":"Andrew","email":"","affiliations":[],"preferred":false,"id":465907,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

In recent years, the bay has experienced hypersaline conditions (salinity greater than 35 practical salinity units) of increasing magnitude and duration. Hypersalinity events were particularly pronounced during April to August 2004 in nearshore areas along the southern and middle parts of the bay. Prolonged hypersaline conditions can cause degradation of water quality and permanent damage to, or loss of, brackish nursery habitats for multiple species of fish and crustaceans as well as damage to certain types of seagrasses that are not tolerant of extreme changes in salinity. To evaluate the factors that contribute to hypersalinity events and to test the effects of possible changes in precipitation patterns and canal flows into Biscayne Bay on salinity in the bay, the U.S. Geological Survey constructed a coupled surface-water/groundwater numerical flow model. The model is designed to account for freshwater flows into Biscayne Bay through the canal system, leakage of salty bay water into the underlying Biscayne aquifer, discharge of fresh and salty groundwater from the Biscayne aquifer into the bay, direct effects of precipitation on bay salinity, indirect effects of precipitation on recharge to the Biscayne aquifer, direct effects of evapotranspiration (ET) on bay salinity, indirect effects of ET on recharge to the Biscayne aquifer, and maintenance of mass balance of both water and solute. The model was constructed using the Flow and Transport in a Linked Overland/Aquifer Density Dependent System (FTLOADDS) simulator, version 3.3, which couples the two-dimensional, surface-water flow and solute-transport simulator SWIFT2D with the density-dependent, groundwater flow an solute-transport simulator SEAWAT. The model was calibrated by a trial-and-error method to fit observed groundwater heads, estimated base flow, and measured bay salinity and temperatures from 1996 to 2004, as well as the location of the freshwater-saltwater interface in the aquifer, by adjusting ET rate limiters, canal vertical hydraulic conductance, leakage rate coefficients (transition-layer thickness and hydraulic conductivity), Manning's n value, and delineation of rainfall zones. Although flow budget calculations indicate that precipitation, ET, and groundwater flux into the bay represent a small portion of the overall budget, these factors may be important in controlling salinity in some parts of the bay, for example the southern parts of the bay where the canal system is not extensively developed or controlled. The balance of precipitation and ET during the wet season generally results in a reduction of bay salinity, whereas the balance of precipitation and ET during the dry season generally results in an increase in bay salinity. During years when wet season precipitation is lower than average, for example less than 70 percent total precipitation for an average year, ET could outweigh precipitation over the bay for essentially the entire year. Hypersaline conditions are prone to occur near the end of the dry season because precipitation rates are generally lower, canal discharge rates (which are strongly correlated to precipitation rates) are also generally lower, and ET rates are higher than during the rest of the year. The hypersalinity event of 2004 followed several years of relatively low precipitation and correspondingly reduced canal structure releases and was unusually extensive, continuing into July. Thus, hypersalinity is ultimately the result of a cumulative deficit of precipitation. The model was used to test the effects of possible changes in canal flux and precipitation. Simulation results showed that by increasing, reducing, or modifying canal discharge rates, the effects on salinity in the bay were more pronounced in the northern part of the bay where there are more canals and canal-control structures. By doubling and halving precipitation, the effects on bay salinity were more pronounced in the southern part of the bay than in the northern part of the bay where there are fewer canals and canal-control structures. The model is designed to quantify factors that contribute to hypersaline conditions in Biscayne Bay and may be less appropriate for addressing other issues or examining conditions substantially different from those described in this report. Model results must be interpreted in light of model limitations, which include representation of the system and conceptual model, uncertainty in physical properties used to describe the system or processes, the scale and discretization of the system, and representation of the boundary conditions.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20125099","collaboration":"Prepared in cooperation with the South Florida Water Management District  Science on the DOI Landscape Initiative","usgsCitation":"Lohmann, M.A., Swain, E.D., Wang, J.D., and Dixon, J., 2012, Evaluation of effects of changes in canal management and precipitation patterns on salinity in Biscayne Bay, Florida, using an integrated surface-water/groundwater model: U.S. Geological Survey Scientific Investigations Report 2012-5099, ix, 94 p.; col. ill.; maps (col.), https://doi.org/10.3133/sir20125099.","productDescription":"ix, 94 p.; col. ill.; maps (col.)","numberOfPages":"108","onlineOnly":"Y","additionalOnlineFiles":"N","costCenters":[{"id":285,"text":"Florida Water Science Center","active":false,"usgs":true}],"links":[{"id":259245,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir_2012_5099.gif"},{"id":259241,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2012/5099/","linkFileType":{"id":5,"text":"html"}},{"id":259242,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2012/5099/pdf/sir_2012_5099_v3.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Florida","otherGeospatial":"Biscyne Bay;Biscayne National Park","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0c6de4b0c8380cd52b40","contributors":{"authors":[{"text":"Lohmann, Melinda A.","contributorId":80133,"corporation":false,"usgs":true,"family":"Lohmann","given":"Melinda","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":465889,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Swain, Eric D. 0000-0001-7168-708X edswain@usgs.gov","orcid":"https://orcid.org/0000-0001-7168-708X","contributorId":1538,"corporation":false,"usgs":true,"family":"Swain","given":"Eric","email":"edswain@usgs.gov","middleInitial":"D.","affiliations":[{"id":27821,"text":"Caribbean-Florida Water Science Center","active":true,"usgs":true}],"preferred":true,"id":465886,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wang, John D.","contributorId":75224,"corporation":false,"usgs":true,"family":"Wang","given":"John","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":465888,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dixon, Joann","contributorId":19981,"corporation":false,"usgs":true,"family":"Dixon","given":"Joann","affiliations":[],"preferred":false,"id":465887,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Empirical models derived from statistical evaluation of data collected from recently burned basins throughout the intermountain western United States were used to estimate the probability of debris-flow occurrence and potential volume of debris flows along the drainage network of the burned area and to estimate the same for 22 selected drainage basins along U.S. Highway 24 and the perimeter of the burned area. Input data for the models included topographic parameters, soil characteristics, burn severity, and rainfall totals and intensities for a (1) 2-year-recurrence, 1-hour-duration rainfall, referred to as a 2-year storm (29 millimeters); (2) 10-year-recurrence, 1-hour-duration rainfall, referred to as a 10-year storm (42 millimeters); and (3) 25-year-recurrence, 1-hour-duration rainfall, referred to as a 25-year storm (48 millimeters). Estimated debris-flow probabilities at the pour points of the the drainage basins of interest ranged from less than 1 to 54 percent in response to the 2-year storm; from less than 1 to 74 percent in response to the 10-year storm; and from less than 1 to 82 percent in response to the 25-year storm. Basins and drainage networks with the highest probabilities tended to be those on the southern and southeastern edge of the burn area where soils have relatively high clay contents and gradients are steep. Nine of the 22 drainage basins of interest have greater than a 40-percent probability of producing a debris flow in response to the 10-year storm. Estimated debris-flow volumes for all rainfalls modeled range from a low of 1,500 cubic meters to a high of greater than 100,000 cubic meters. Estimated debris-flow volumes increase with basin size and distance along the drainage network, but some smaller drainages were also predicted to produce substantial volumes of material. The predicted probabilities and some of the volumes predicted for the modeled storms indicate a potential for substantial debris-flow impacts on structures, reservoirs, roads, bridges, and culverts located both within and immediately downstream from the burned area. U.S. Highway 24, on the southern edge of the burn area, is also susceptible to impacts from debris flows.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20121158","collaboration":"Prepared in cooperation with Colorado Department of Transportation","usgsCitation":"Verdin, K.L., Dupree, J.A., and Elliott, J.G., 2012, Probability and volume of potential postwildfire debris flows in the 2012 Waldo Canyon Burn Area near Colorado Springs, Colorado: U.S. Geological Survey Open-File Report 2012-1158, vi, 8 p.; maps (col.); 2 Plates: 34 x 22 inches, https://doi.org/10.3133/ofr20121158.","productDescription":"vi, 8 p.; maps (col.); 2 Plates: 34 x 22 inches","startPage":"i","endPage":"8","numberOfPages":"14","onlineOnly":"Y","additionalOnlineFiles":"Y","temporalStart":"2012-06-23","temporalEnd":"2012-07-30","costCenters":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"links":[{"id":259246,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2012_1158.gif"},{"id":259244,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2012/1158/OF12-1158.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":259243,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2012/1158/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Colorado","county":"El Paso County","city":"Colorado Springs","otherGeospatial":"Waldo Canyon","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a8ca9e4b0c8380cd7e7fc","contributors":{"authors":[{"text":"Verdin, Kristine L. 0000-0002-6114-4660 kverdin@usgs.gov","orcid":"https://orcid.org/0000-0002-6114-4660","contributorId":3070,"corporation":false,"usgs":true,"family":"Verdin","given":"Kristine","email":"kverdin@usgs.gov","middleInitial":"L.","affiliations":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true},{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"preferred":true,"id":465892,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dupree, Jean A. dupree@usgs.gov","contributorId":2563,"corporation":false,"usgs":true,"family":"Dupree","given":"Jean","email":"dupree@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":465891,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Elliott, John G. jelliott@usgs.gov","contributorId":832,"corporation":false,"usgs":true,"family":"Elliott","given":"John","email":"jelliott@usgs.gov","middleInitial":"G.","affiliations":[],"preferred":true,"id":465890,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

King eiders spend most of their lives in remote areas, forcing managers to make regulatory and conservation decisions based on very little information. We incorporated available published estimates of vital rates with new estimates to build a female, stage-based matrix population model for king eiders and examine the processes underlying population dynamics of king eiders breeding at 2 sites, Teshekpuk and Kuparuk, on the coastal plain of northern Alaska and wintering around the Bering Sea (2001&ndash;2010). We predicted a decreasing population (<i>&lambda;</i> = 0.981, 95% CI: 0.978&ndash;0.985), and that population growth was most sensitive to changes in adult female survival (sensitivity = 0.92). Low duckling survival may be a bottleneck to productivity (variation in ducking survival accounted for 66% of retrospective variation in <i>&lambda;</i>). Adult survival was high (0.94) and invariant (<i>&sigma;</i> = 0.0002, 95% CI: 0.0000&ndash;0.0007); however, catastrophic events could have a major impact and we need to consider how to mitigate and manage threats to adult survival. A hypothetical oil spill affecting breeding females in a primary spring staging area resulted in a severe population decline; although, transient population dynamics were relatively stable. However, if no catastrophic events occur, the more variable reproductive parameters (duckling and nest survival) may be more responsive to management actions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Wildlife Society","publisherLocation":"Bethesda, MD","doi":"10.1002/jwmg.335","usgsCitation":"Bentzen, R., and Powell, A., 2012, Population dynamics of king eiders breeding in northern Alaska: Journal of Wildlife Management, v. 76, no. 5, p. 1011-1020, https://doi.org/10.1002/jwmg.335.","productDescription":"10 p.","startPage":"1011","endPage":"1020","costCenters":[{"id":108,"text":"Alaska Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":259268,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259257,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/jwmg.335","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Alaska","volume":"76","issue":"5","noUsgsAuthors":false,"publicationDate":"2012-02-06","publicationStatus":"PW","scienceBaseUri":"505a7d4de4b0c8380cd79e86","contributors":{"authors":[{"text":"Bentzen, Rebecca L.","contributorId":62070,"corporation":false,"usgs":true,"family":"Bentzen","given":"Rebecca L.","affiliations":[],"preferred":false,"id":348809,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Powell, Abby N. abby_powell@usgs.gov","contributorId":2534,"corporation":false,"usgs":false,"family":"Powell","given":"Abby N.","email":"abby_powell@usgs.gov","affiliations":[{"id":13117,"text":"Institute of Arctic Biology, University of Alaska Fairbanks","active":true,"usgs":false}],"preferred":false,"id":348808,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Time series data stacks were generated for four study areas: (1) a four scene area dominated by forest and rangeland ecosystems in the southwestern United States, (2) a sagebrush-dominated rangeland in Wyoming, (3) woodland adjacent to prairie in northwestern Nebraska, and (4) a forested area in the White Mountains of New Hampshire. Through analyses of time series data, we found evidence of gradual systematic change in many of the natural vegetation communities in all four areas. Many of the conifer forests in the southwestern US are showing declines related to insects and drought, but very few are showing evidence of improving conditions or increased greenness. Sagebrush communities are showing decreases in greenness related to fire, mining, and probably drought, but very few of these communities are showing evidence of increased greenness or improving conditions. In Nebraska, forest communities are showing local expansion and increased canopy densification in the prairie&ndash;woodland interface, and in the White Mountains high elevation understory conifers are showing range increases towards lower elevations. The trends detected are not obvious through casual inspection of the Landsat images. Analyses of time series data using many scenes and covering multiple years are required in order to develop better impressions and representations of the changing ecosystem patterns and trends that are occurring. The approach described in this paper demonstrates that Landsat time series data can be used operationally for assessing gradual ecosystem change across large areas. Local knowledge and available ancillary data are required in order to fully understand the nature of these trends.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Remote Sensing of Environment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.rse.2011.06.027","usgsCitation":"Vogelmann, J., Xian, G., Homer, C.G., and Tolk, B., 2012, Monitoring gradual ecosystem change using Landsat time series analyses: case studies in selected forest and rangeland ecosystems: Remote Sensing of Environment, v. 122, p. 92-105, https://doi.org/10.1016/j.rse.2011.06.027.","productDescription":"14 p.","startPage":"92","endPage":"105","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":259239,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257288,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.1016/j.rse.2011.06.027","linkFileType":{"id":5,"text":"html"}}],"country":"United States","volume":"122","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5dafe4b0c8380cd70523","contributors":{"authors":[{"text":"Vogelmann, James E. 0000-0002-0804-5823 vogel@usgs.gov","orcid":"https://orcid.org/0000-0002-0804-5823","contributorId":649,"corporation":false,"usgs":true,"family":"Vogelmann","given":"James E.","email":"vogel@usgs.gov","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":false,"id":355952,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Xian, George 0000-0001-5674-2204","orcid":"https://orcid.org/0000-0001-5674-2204","contributorId":76589,"corporation":false,"usgs":true,"family":"Xian","given":"George","affiliations":[],"preferred":false,"id":355955,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Homer, Collin G. 0000-0003-4755-8135 homer@usgs.gov","orcid":"https://orcid.org/0000-0003-4755-8135","contributorId":2262,"corporation":false,"usgs":true,"family":"Homer","given":"Collin","email":"homer@usgs.gov","middleInitial":"G.","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true},{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"preferred":true,"id":355953,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Tolk, Brian 0000-0002-9060-0266","orcid":"https://orcid.org/0000-0002-9060-0266","contributorId":62426,"corporation":false,"usgs":true,"family":"Tolk","given":"Brian","affiliations":[],"preferred":false,"id":355954,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

This species-specific tolerance to rotenone has been thought to be associated with the uptake and the efficiency at which the chemical is detoxified. However, rotenone stimulates oxidative stress and superoxides, which are also toxic. Understanding the modes in which fish physiologically respond to rotenone is important in developing improved protocols for its application in controlling aquatic nuisance species. Using a molecular approach, we investigated the physiological and molecular mechanisms of rotenone resistance. Species-specific responses were observed when rotenone-sensitive silver, Hypophthalmichthys molitrix, and both rotenone-resistant bighead carp, Hypophthalmichthys nobilis, and bigmouth buffalo, Ictiobus cyprinellus, were exposed to rotenone. Rotenone levels in plasma were highest 90 min after exposure in both silver carp and bigmouth buffalo, but bigmouth buffalo tolerated over twice the burden (ng mL<sup>-1</sup> g<sup>-1</sup>) than silver carp. Expression of genes related with detoxification (<i>cyp1a</i> and <i>gst</i>) increased in silver carp, but either decreased or remained the same in bighead carp. Genes linked with oxidative stress in the cytosol (<i>gpx</i>, <i>cat</i> and <i>sod1</i>) and <i>hsp70</i> increased only in silver carp after a 6-h exposure. Expression of genes associated with oxidative stress in the mitochondria (<i>sod2</i> and <i>ucp2</i>) differed between silver carp and bighead carp. Expression of <i>sod2</i> changed minimally in bighead carp, but expression of <i>ucp2</i> linearly increased to nearly 85-fold of the level prior to exposure. Expression of <i>sod2</i> and <i>ucp2</i> did not change until 6 h in silver carp. Use of <i>sod1</i> and <i>sod2</i> to combat oxidative stress results in hydrogen peroxide production, while use of <i>ucp2</i> produces nitric oxide, a chemical known to inhibit apoptosis. We conclude that the mechanism at which a fish handles oxidative stress plays an important role in the tolerance to rotenone.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Fish Physiology and Biochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s10695-012-9625-1","usgsCitation":"Amberg, J., Schreier, T.M., and Gaikowski, M.P., 2012, Molecular responses differ between sensitive silver carp and tolerant bighead carp and bigmouth buffalo exposed to rotenone: Fish Physiology and Biochemistry, v. 38, no. 5, p. 1379-1391, https://doi.org/10.1007/s10695-012-9625-1.","productDescription":"13 p.","startPage":"1379","endPage":"1391","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":259240,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257281,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.1007/s10695-012-9625-1","linkFileType":{"id":5,"text":"html"}}],"volume":"38","issue":"5","noUsgsAuthors":false,"publicationDate":"2012-03-25","publicationStatus":"PW","scienceBaseUri":"505a5d11e4b0c8380cd70133","contributors":{"authors":[{"text":"Amberg, Jon J. jamberg@usgs.gov","contributorId":797,"corporation":false,"usgs":true,"family":"Amberg","given":"Jon J.","email":"jamberg@usgs.gov","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":false,"id":463066,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schreier, Theresa M. 0000-0001-7722-6292 tschreier@usgs.gov","orcid":"https://orcid.org/0000-0001-7722-6292","contributorId":3344,"corporation":false,"usgs":true,"family":"Schreier","given":"Theresa","email":"tschreier@usgs.gov","middleInitial":"M.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":463067,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gaikowski, Mark P. 0000-0002-6507-9341 mgaikowski@usgs.gov","orcid":"https://orcid.org/0000-0002-6507-9341","contributorId":796,"corporation":false,"usgs":true,"family":"Gaikowski","given":"Mark","email":"mgaikowski@usgs.gov","middleInitial":"P.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":false,"id":463065,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Here we use discontinuity analyses to investigate nonlinear patterns in the distribution of biomass of an invasive nuisance species that could indicate scale-specific organization. We analyze biomass patterns in the flagellate Gonyostomum semen (Raphidophyta) in 75 boreal lakes during an 11-year period (1997-2007). With simulations using a unimodal null model and cluster analysis, we identified regional groupings of lakes based on their biomass patterns. We evaluated the variability of membership of individual lakes in regional biomass groups. Temporal trends in local and regional discontinuity patterns were analyzed using regressions and correlations with environmental variables that characterize nutrient conditions, acidity status, temperature variability, and water clarity. Regionally, there was a significant increase in the number of biomass groups over time, indicative of an increased number of scales at which algal biomass organizes across lakes. This increased complexity correlated with the invasion history of G. semen and broad-scale environmental change (recovery from acidification). Locally, no consistent patterns of lake membership to regional biomass groups were observed, and correlations with environmental variables were lake specific. The increased complexity of regional biomass patterns suggests that processes that act within or between scales reinforce the presence of G. semen and its potential to develop high-biomass blooms in boreal lakes. Emergent regional patterns combined with locally stochastic dynamics suggest a bleak future for managing G. semen, and more generally why invasive species can be ecologically successful.</p>","language":"English","publisher":"The Resilience Alliance","doi":"10.5751/ES-04928-170232","usgsCitation":"Angeler, D., Allen, C.R., and Johnson, R.K., 2012, Insight on invasions and resilience derived from spatiotemporal discontinuities of biomass at local and regional scales: Ecology and Society, v. 17, no. 2, 15 p.; Article 32, https://doi.org/10.5751/ES-04928-170232.","productDescription":"15 p.; Article 32","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-037249","costCenters":[{"id":463,"text":"Nebraska Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":488008,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5751/es-04928-170232","text":"Publisher Index Page"},{"id":259236,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259227,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.5751/ES-04928-170232","linkFileType":{"id":5,"text":"html"}}],"volume":"17","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3c1ee4b0c8380cd62aa3","contributors":{"authors":[{"text":"Angeler, David G.","contributorId":25027,"corporation":false,"usgs":true,"family":"Angeler","given":"David G.","affiliations":[],"preferred":false,"id":350832,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Allen, Criag R.","contributorId":72247,"corporation":false,"usgs":true,"family":"Allen","given":"Criag","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":350833,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Johnson, Richard K.","contributorId":21810,"corporation":false,"usgs":true,"family":"Johnson","given":"Richard","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":350831,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

When considering habitat prioritization, we need to explicitly consider habitat requirements throughout the annual cycle, particularly for species of conservation concern. Understanding annual habitat requirements begins with quantifying how far individuals move across landscapes between key life stages to access required habitats. We quantified individual interseasonal movements for greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) using radio-telemetry spanning the majority of the species distribution in Wyoming. Sage-grouse are currently a candidate for listing under the United States Endangered Species Act and Wyoming is predicted to remain a stronghold for the species. Sage-grouse use distinct seasonal habitats throughout their annual cycle for breeding, brood rearing, and wintering. Average movement distances in Wyoming from nest sites to summer-late brood-rearing locations were 8.1 km (SE = 0.3 km; <i>n</i> = 828 individuals) and the average subsequent distances moved from summer sites to winter locations were 17.3 km (SE = 0.5 km; <i>n</i> = 607 individuals). Average nest-to-winter movements were 14.4 km (SE = 0.6 km; <i>n</i> = 434 individuals). We documented remarkable variation in the extent of movement distances both within and among sites across Wyoming, with some individuals remaining year-round in the same vicinity and others moving over 50 km between life stages. Our results suggest defining any of our populations as migratory or non-migratory is innappropriate as individual strategies vary widely. We compared movement distances of birds marked using Global Positioning System (GPS) and very high frequency (VHF) radio marking techniques and found no evidence that the heavier GPS radios limited movement. Furthermore, we examined the capacity of the sage-grouse core regions concept to capture seasonal locations. As expected, we found the core regions approach, which was developed based on lek data, was generally better at capturing the nesting locations than summer or winter locations. However, across Wyoming the sage-grouse breeding core regions still contained a relatively high percentage of summer and winter locations and seem to be a reasonable surrogate for non-breeding habitat when no other information exists. We suggest that conservation efforts for greater sage-grouse implicitly incorporate seasonal habitat needs because of high variation in the amount of overlap among breeding core regions and non-breeding habitat.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal

The focus of the modeling study was the Paleocene and Eocene Wilcox Formation, which contains the youngest source rock interval in the Gulf Coast Province. Stratigraphic input to the models included thicknesses and ages of deposition, lithologies, amounts and ages of erosion, and ages for periods of nondeposition. Oil-generation potential of the Wilcox Formation was modeled using an initial total organic carbon of 2 weight percent and an initial hydrogen index of 261 milligrams of hydrocarbon per grams of total organic carbon. Isothermal, hydrous-pyrolysis kinetics determined experimentally was used to simulate oil generation from coal, which is the primary source of oil in Eocene rocks. Model simulations indicate that generation of oil commenced in the Wilcox Formation during a fairly wide age range, from 37 million years ago to the present day. Differences in maturity with respect to oil generation occur across the Lower Cretaceous shelf edge. Source rocks that are thermally immature and have not generated oil (depths less than about 5,000 feet) lie updip and north of the shelf edge; source rocks that have generated all of their oil and are overmature (depths greater than about 13,000 feet) are present downdip and south of the shelf edge. High rates of sediment deposition coupled with increased accommodation space at the Cretaceous shelf margin led to deep burial of Cretaceous and Tertiary source rocks and, in turn, rapid generation of petroleum and, ultimately, cracking of oil to gas.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20121046","usgsCitation":"Pitman, J.K., and Rowan, E., 2012, Temperature and petroleum generation history of the Wilcox Formation, Louisiana: U.S. Geological Survey Open-File Report 2012-1046, iv, 51 p.; ill.

Groundwater from residential-supply wells in a fractured crystalline-rock aquifer adjacent to a Superfund site in Raymond, New Hampshire, USA, showed evidence of locally enhanced As mobilization in relatively reducing (mixed oxic-anoxic to anoxic) conditions as determined by redox classification and other lines of evidence. Redox classification was determined from geochemical indicators based on threshold concentrations of dissolved oxygen (DO), nitrate (NO<sup>3-</sup>), iron (Fe<sup>2+</sup>), manganese (Mn<sup>2+</sup>), and sulfate (SO<sub>4</sub><sup>2-</sup>). Redox conditions were evaluated also based on methane (CH<sub>4</sub>), excess nitrogen gas (N<sub>2</sub>) from denitrification, the oxidation state of dissolved As speciation (As(III) and As(V)), and several stable isotope ratios. Samples from the residential-supply wells primarily exhibit mixed redox conditions, as most have long open boreholes (typically 50&ndash;100 m) that receive water from multiple discrete fractures with contrasting groundwater chemistry and redox conditions. The methods employed in this study can be used at other sites to gauge redox conditions and the potential for As mobilization in complex fractured crystalline-rock aquifers where multiple lines of evidence are likely needed to understand As occurrence, mobility, and transport.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrogeology Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s10040-012-0844-4","usgsCitation":"Harte, P.T., Ayotte, J., Hoffman, A., Revesz, K.M., Belaval, M., Lamb, S., and Böhlke, J., 2012, Heterogeneous redox conditions, arsenic mobility, and groundwater flow in a fractured-rock aquifer near a waste repository site in New Hampshire, USA: Hydrogeology Journal, v. 20, no. 6, p. 1189-1201, https://doi.org/10.1007/s10040-012-0844-4.","productDescription":"13 p.","startPage":"1189","endPage":"1201","numberOfPages":"13","costCenters":[{"id":468,"text":"New Hampshire-Vermont Water Science Center","active":false,"usgs":true}],"links":[{"id":259238,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259222,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10040-012-0844-4","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"New Hampshire","volume":"20","issue":"6","noUsgsAuthors":false,"publicationDate":"2012-04-28","publicationStatus":"PW","scienceBaseUri":"505a308fe4b0c8380cd5d749","contributors":{"authors":[{"text":"Harte, Philip T. 0000-0002-7718-1204 ptharte@usgs.gov","orcid":"https://orcid.org/0000-0002-7718-1204","contributorId":1008,"corporation":false,"usgs":true,"family":"Harte","given":"Philip","email":"ptharte@usgs.gov","middleInitial":"T.","affiliations":[{"id":466,"text":"New England Water Science Center","active":true,"usgs":true},{"id":405,"text":"NH/VT office of New England Water Science Center","active":true,"usgs":true}],"preferred":true,"id":465372,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ayotte, Joseph D. jayotte@usgs.gov","contributorId":1802,"corporation":false,"usgs":true,"family":"Ayotte","given":"Joseph D.","email":"jayotte@usgs.gov","affiliations":[{"id":466,"text":"New England Water Science Center","active":true,"usgs":true}],"preferred":false,"id":465373,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hoffman, Andrew","contributorId":100674,"corporation":false,"usgs":true,"family":"Hoffman","given":"Andrew","email":"","affiliations":[],"preferred":false,"id":465377,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Revesz, Kinga M. krevesz@usgs.gov","contributorId":506,"corporation":false,"usgs":true,"family":"Revesz","given":"Kinga","email":"krevesz@usgs.gov","middleInitial":"M.","affiliations":[],"preferred":true,"id":465371,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Belaval, Marcel","contributorId":21636,"corporation":false,"usgs":true,"family":"Belaval","given":"Marcel","affiliations":[],"preferred":false,"id":465374,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Lamb, Steven","contributorId":35580,"corporation":false,"usgs":true,"family":"Lamb","given":"Steven","email":"","affiliations":[],"preferred":false,"id":465375,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Böhlke, J.K. 0000-0001-5693-6455","orcid":"https://orcid.org/0000-0001-5693-6455","contributorId":96696,"corporation":false,"usgs":true,"family":"Böhlke","given":"J.K.","affiliations":[],"preferred":false,"id":465376,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

These models demonstrate similar climate fidelity as the Geophysical Fluid Dynamics Laboratory's previous CM2.1 climate model while incorporating explicit and consistent carbon dynamics. The two models differ exclusively in the physical ocean component; ESM2M uses Modular Ocean Model version 4.1 with vertical pressure layers while ESM2G uses Generalized Ocean Layer Dynamics with a bulk mixed layer and interior isopycnal layers. Differences in the ocean mean state include the thermocline depth being relatively deep in ESM2M and relatively shallow in ESM2G compared to observations. The crucial role of ocean dynamics on climate variability is highlighted in the El Ni&ntilde;o-Southern Oscillation being overly strong in ESM2M and overly weak ESM2G relative to observations. Thus, while ESM2G might better represent climate changes relating to: total heat content variability given its lack of long term drift, gyre circulation and ventilation in the North Pacific, tropical Atlantic and Indian Oceans, and depth structure in the overturning and abyssal flows, ESM2M might better represent climate changes relating to: surface circulation given its superior surface temperature, salinity and height patterns, tropical Pacific circulation and variability, and Southern Ocean dynamics. Our overall assessment is that neither model is fundamentally superior to the other, and that both models achieve sufficient fidelity to allow meaningful climate and earth system modeling applications. This affords us the ability to assess the role of ocean configuration on earth system interactions in the context of two state-of-the-art coupled carbon-climate models.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Climate","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Meteorological Society","publisherLocation":"Boston, MA","doi":"10.1175/JCLI-D-11-00560.1","usgsCitation":"Dunne, J.P., John, J.G., Adcroft, A.J., Griffies, S.M., Hallberg, R., Shevalikova, E., Stouffer, R., Cooke, W., Dunne, K.A., Harrison, M., Krasting, J.P., Malyshev, S.L., Milly, P., Phillipps, P.J., Sentman, L., Samuels, B.L., Spelman, M.J., Winton, M., Wittenberg, A., and Zadeh, N., 2012, GFDL's ESM2 global coupled climate-carbon Earth System Models.

The habitats and resources needed to support breeding performance of grassland birds endemic to prairie ecosystems are currently threatened by land management practices and impending climate change. Climate models for the Great Plains prairie region predict a future of hotter and drier summers with strong multiyear droughts and more frequent and severe precipitation events. We examined how fluctuations in weather conditions in eastern Colorado influenced nest survival of an avian species that has experienced recent population declines, the Mountain Plover (Charadrius montanus). Nest survival averaged 27.2% over a 7-yr period (n = 936 nests) and declined as the breeding season progressed. Nest survival was favored by dry conditions and cooler temperatures. Projected changes in regional precipitation patterns will likely influence nest survival, with positive influences of predicted declines in summer rainfall yet negative effects of more intense rain events. The interplay of climate change and land use practices within prairie ecosystems may result in Mountain Plovers shifting their distribution, changing local abundance, and adjusting fecundity to adapt to their changing environment.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Avian Conservation and Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Resillience Alliance","publisherLocation":"Wolfville, Nova Scotia","doi":"10.5751/ACE-00519-070106","usgsCitation":"Dreitz, V., Conrey, R., and Skagen, S., 2012, Drought and cooler temperatures are associated with higher nest survival in Mountain Plovers: Avian Conservation and Ecology, v. 7, no. 1, 13 p.; Article 6, https://doi.org/10.5751/ACE-00519-070106.","productDescription":"13 p.; Article 6","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":474401,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5751/ace-00519-070106","text":"Publisher Index Page"},{"id":259194,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259189,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.5751/ACE-00519-070106","linkFileType":{"id":5,"text":"html"}}],"country":"United States","volume":"7","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a03f4e4b0c8380cd50700","contributors":{"authors":[{"text":"Dreitz, V.J.","contributorId":65432,"corporation":false,"usgs":true,"family":"Dreitz","given":"V.J.","affiliations":[],"preferred":false,"id":463412,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Conrey, R.Y.","contributorId":43222,"corporation":false,"usgs":true,"family":"Conrey","given":"R.Y.","email":"","affiliations":[],"preferred":false,"id":463411,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Skagen, S.

In this study, SNODAS snow depth and SWE estimates were compared with independent, ground-based snow survey data in the Colorado Rocky Mountains to assess SNODAS accuracy at the 1-km<sup>2</sup> scale. Accuracy also was evaluated at the basin scale by comparing SNODAS model output to snowmelt runoff in 31 headwater basins with US Geological Survey stream gauges. Results from the snow surveys indicated that SNODAS performed well in forested areas, explaining 72% of the variance in snow depths and 77% of the variance in SWE. However, SNODAS showed poor agreement with measurements in alpine areas, explaining 16% of the variance in snow depth and 30% of the variance in SWE. At the basin scale, snowmelt runoff was moderately correlated (<i>R</i><sup>2</sup> = 0.52) with SNODAS model estimates. A simple method for adjusting SNODAS SWE estimates in alpine areas was developed that uses relations between prevailing wind direction, terrain, and vegetation to account for wind redistribution of snow in alpine terrain. The adjustments substantially improved agreement between measurements and SNODAS estimates, with the <i>R</i><sup>2</sup> of measured SWE values against SNODAS SWE estimates increasing from 0.42 to 0.63 and the root mean square error decreasing from 12 to 6 cm. Results from this study indicate that SNODAS can provide reliable data for input to moderate-scale to large-scale hydrologic models, which are essential for creating accurate runoff forecasts. Refinement of SNODAS SWE estimates for alpine areas to account for wind redistribution of snow could further improve model performance. Published 2011.

A set of 30 wells was visited once in 1993&ndash;1995 and again in 2008&ndash;2009 to assess concentration changes. The data include censored matched pairs (nondetections of a compound in one or both samples of a pair). A potentially improved approach for assessing concentration changes is presented where (i) concentrations are adjusted with models of matrix-spike recovery and (ii) area-wide temporal change is tested by use of the paired Prentice-Wilcoxon (PPW) statistical test. The PPW results for atrazine, simazine, metolachlor, prometon, and an atrazine degradate, deethylatrazine (DEA), are compared using recovery-adjusted and unadjusted concentrations. Results for adjusted compared with unadjusted concentrations in 2008&ndash;2009 compared with 1993&ndash;1995 were similar for atrazine and simazine (significant decrease; 95% confidence level) and metolachlor (no change) but differed for DEA (adjusted, decrease; unadjusted, increase) and prometon (adjusted, decrease; unadjusted, no change). The PPW results were different on recovery-adjusted compared with unadjusted concentrations. Not accounting for variability in recovery can mask a true change, misidentify a change when no true change exists, or assign a direction opposite of the true change in concentration that resulted from matrix influences on extraction and laboratory method performance. However, matrix-based models of recovery derived from a laboratory performance dataset from multiple studies for national assessment, as used herein, rather than time- and study-specific recoveries may introduce uncertainty in recovery adjustments for individual samples that should be considered in assessing change.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Environmental Quality","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"ACSESS DL","publisherLocation":"Madison, WI","doi":"10.2134/jeq2011.0271","usgsCitation":"Zimmerman, T.M., and Breen, K.J., 2012, Evaluating changes in matrix based, recovery-adjusted concentrations in paired data for pesticides in groundwater: Journal of Environmental Quality, v. 41, no. 4, p. 1238-1245, https://doi.org/10.2134/jeq2011.0271.","productDescription":"8 p.","startPage":"1238","endPage":"1245","costCenters":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"links":[{"id":259216,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259202,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2134/jeq2011.0271","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Pennsylvania","volume":"41","issue":"4","noUsgsAuthors":false,"publicationDate":"2012-07-01","publicationStatus":"PW","scienceBaseUri":"505a0bdce4b0c8380cd528fa","contributors":{"authors":[{"text":"Zimmerman, Tammy M. 0000-0003-0842-6981 tmzimmer@usgs.gov","orcid":"https://orcid.org/0000-0003-0842-6981","contributorId":2359,"corporation":false,"usgs":true,"family":"Zimmerman","given":"Tammy","email":"tmzimmer@usgs.gov","middleInitial":"M.","affiliations":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"preferred":false,"id":354257,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Breen, Kevin J. 0000-0002-9447-6469 kjbreen@usgs.gov","orcid":"https://orcid.org/0000-0002-9447-6469","contributorId":219,"corporation":false,"usgs":true,"family":"Breen","given":"Kevin","email":"kjbreen@usgs.gov","middleInitial":"J.","affiliations":[{"id":501,"text":"Office of Science Quality and Integrity","active":true,"usgs":true}],"preferred":true,"id":354256,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Methanotrophs in lake sediments and water columns mitigate the amount of CH<sub>4</sub> that enters the atmosphere, yet their identity and activity in arctic and subarctic lakes are poorly understood. We used stable isotope probing (SIP), quantitative PCR (Q-PCR), pyrosequencing and enrichment cultures to determine the identity and diversity of active aerobic methanotrophs in the water columns and sediments (0&ndash;25 cm) from an arctic tundra lake (Lake Qalluuraq) on the north slope of Alaska and a subarctic taiga lake (Lake Killarney) in Alaska's interior. The water column CH<sub>4</sub> oxidation potential for these shallow (~2m deep) lakes was greatest in hypoxic bottom water from the subarctic lake. The type II methanotroph, Methylocystis, was prevalent in enrichment cultures of planktonic methanotrophs from the water columns. In the sediments, type I methanotrophs (Methylobacter, Methylosoma and Methylomonas) at the sediment-water interface (0&ndash;1 cm) were most active in assimilating CH<sub>4</sub>, whereas the type I methanotroph Methylobacter and/or type II methanotroph Methylocystis contributed substantially to carbon acquisition in the deeper (15&ndash;20 cm) sediments. In addition to methanotrophs, an unexpectedly high abundance of methylotrophs also actively utilized CH<sub>4</sub>-derived carbon. This study provides new insight into the identity and activity of methanotrophs in the sediments and water from high-latitude lakes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"ISME Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Nature Publishing Group","publisherLocation":"Washington, D.C.","doi":"10.1038/ismej.2012.34","usgsCitation":"He, R., Wooller, M., Pohlman, J., Quensen, J., Tiedje, J.M., and Leigh, M.B., 2012, Diversity of active aerobic methanotrophs along depth profiles of arctic and subarctic lake water column and sediments: ISME Journal, v. 6, no. 10, p. 1937-1948, https://doi.org/10.1038/ismej.2012.34.","productDescription":"12 p.","startPage":"1937","endPage":"1948","numberOfPages":"53","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":474397,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1038/ismej.2012.34","text":"Publisher Index Page"},{"id":259191,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259188,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1038/ismej.2012.34","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Alaska","otherGeospatial":"Lake Qalluuraq;Lake Kilarney","volume":"6","issue":"10","noUsgsAuthors":false,"publicationDate":"2012-05-17","publicationStatus":"PW","scienceBaseUri":"505a0351e4b0c8380cd5041c","contributors":{"authors":[{"text":"He, Ruo","contributorId":53222,"corporation":false,"usgs":true,"family":"He","given":"Ruo","email":"","affiliations":[],"preferred":false,"id":464688,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wooller, Matthew J.","contributorId":24213,"corporation":false,"usgs":true,"family":"Wooller","given":"Matthew J.","affiliations":[],"preferred":false,"id":464684,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Pohlman, John W.","contributorId":95288,"corporation":false,"usgs":true,"family":"Pohlman","given":"John W.","affiliations":[],"preferred":false,"id":464689,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Quensen, John","contributorId":24214,"corporation":false,"usgs":true,"family":"Quensen","given":"John","email":"","affiliations":[],"preferred":false,"id":464685,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Tiedje, James M.","contributorId":37591,"corporation":false,"usgs":true,"family":"Tiedje","given":"James","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":464687,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Leigh, Mary Beth","contributorId":25028,"corporation":false,"usgs":true,"family":"Leigh","given":"Mary","email":"","middleInitial":"Beth","affiliations":[],"preferred":false,"id":464686,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

As a society, we continually seek to reduce flood impacts, with these efforts loosely grouped into two categories: mitigation and risk awareness. Mitigation involves such activities as flood assessment, flood control implementation, and regulatory activities such as storm water and floodplain ordinances. Risk awareness ranges from issuance of flood forecasts and warnings to education of lay audiences about the uncertainties inherent in assessing flood probability and risk. This paper concentrates on the issue of flood risk awareness, specifically the importance of hydrologic data and good interagency communication in providing accurate and timely flood forecasts to maximize risk awareness. The 2011 floods in the central United States provide a case study of the importance of hydrologic data and the value of proper, timely, and organized communication and collaboration around the collection and dissemination of that hydrologic data in enhancing the effectiveness of flood forecasting and flood risk awareness.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Leadership and Management in Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"ASCE","publisherLocation":"Reston, VA","doi":"10.1061/(ASCE)LM.1943-5630.0000181","usgsCitation":"Holmes, R.R., Schwein, N.O., and Shadie, C.E., 2012, Flood risk awareness during the 2011 floods in the central United States: showcasing the importance of hydrologic data and interagency collaboration: Leadership and Management in Engineering, v. 12, no. 3, p. 101-110, https://doi.org/10.1061/(ASCE)LM.1943-5630.0000181.","productDescription":"10 p.","startPage":"101","endPage":"110","numberOfPages":"18","temporalStart":"2011-01-01","temporalEnd":"2011-12-31","costCenters":[{"id":502,"text":"Office of Surface Water","active":true,"usgs":true}],"links":[{"id":474396,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1061/(asce)lm.1943-5630.0000181","text":"Publisher Index Page"},{"id":259220,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259205,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/(ASCE)LM.1943-5630.0000181","linkFileType":{"id":5,"text":"html"}}],"country":"United States","volume":"12","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1150e4b0c8380cd53f62","contributors":{"authors":[{"text":"Holmes, Robert R.

In landscapes still occupied by large carnivores, many ungulate prey species migrate seasonally, yet little empirical research has explored the relationship between carnivore distribution and ungulate migration strategy. In this study, we evaluate the influence of elk (<i>Cervus elaphus</i>) distribution and other landscape features on wolf (<i>Canis lupus</i>) habitat use in an area of chronic wolf&ndash;livestock conflict in the Greater Yellowstone Ecosystem, USA. Using three years of fine-scale wolf (<i>n</i> = 14) and elk (<i>n</i> = 81) movement data, we compared the seasonal habitat use of wolves in an area dominated by migratory elk with that of wolves in an adjacent area dominated by resident elk. Most migratory elk vacate the associated winter wolf territories each summer via a 40&ndash;60 km migration, whereas resident elk remain accessible to wolves year-round. We used a generalized linear model to compare the relative probability of wolf use as a function of GIS-based habitat covariates in the migratory and resident elk areas. Although wolves in both areas used elk-rich habitat all year, elk density in summer had a weaker influence on the habitat use of wolves in the migratory elk area than the resident elk area. Wolves employed a number of alternative strategies to cope with the departure of migratory elk. Wolves in the two areas also differed in their disposition toward roads. In winter, wolves in the migratory elk area used habitat close to roads, while wolves in the resident elk area avoided roads. In summer, wolves in the migratory elk area were indifferent to roads, while wolves in resident elk areas strongly avoided roads, presumably due to the location of dens and summering elk combined with different traffic levels. Study results can help wildlife managers to anticipate the movements and establishment of wolf packs as they expand into areas with migratory or resident prey populations, varying levels of human activity, and front-country rangelands with potential for conflicts with livestock.</p>","language":"English","publisher":"ESA","doi":"10.1890/11-1829.1","usgsCitation":"Nelson, A., Kauffman, M., Middleton, A., Jimenez, M., McWhirter, D., Barber, J., and Gerow, K., 2012, Elk migration patterns and human activity influence wolf habitat use in the Greater Yellowstone Ecosystem: Ecological Applications, v. 22, no. 8, p. 2293-2307, https://doi.org/10.1890/11-1829.1.","productDescription":"15 p.","startPage":"2293","endPage":"2307","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-033306","costCenters":[{"id":683,"text":"Wyoming Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":259201,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259197,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/11-1829.1","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Wyoming","city":"Cody","otherGeospatial":"Yellowstone National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -110.4985,44.3159 ], [ -110.4985,45.0003 ], [ -108.9289,45.0003 ], [ -108.9289,44.3159 ], [ -110.4985,44.3159 ] ] ] } } ] }","volume":"22","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a08dde4b0c8380cd51cd7","contributors":{"authors":[{"text":"Nelson, Abigail","contributorId":47258,"corporation":false,"usgs":true,"family":"Nelson","given":"Abigail","affiliations":[],"preferred":false,"id":464304,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kauffman, Matthew J. 0000-0003-0127-3900 mkauffman@usgs.gov","orcid":"https://orcid.org/0000-0003-0127-3900","contributorId":2963,"corporation":false,"usgs":true,"family":"Kauffman","given":"Matthew J.","email":"mkauffman@usgs.gov","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":464300,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Middleton, Arthur D.","contributorId":99440,"corporation":false,"usgs":true,"family":"Middleton","given":"Arthur D.","affiliations":[],"preferred":false,"id":464306,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jimenez, Mike","contributorId":33785,"corporation":false,"usgs":true,"family":"Jimenez","given":"Mike","email":"","affiliations":[],"preferred":false,"id":464302,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"McWhirter, Douglas","contributorId":7577,"corporation":false,"usgs":true,"family":"McWhirter","given":"Douglas","affiliations":[],"preferred":false,"id":464301,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Barber, Jarrett","contributorId":94935,"corporation":false,"usgs":true,"family":"Barber","given":"Jarrett","affiliations":[],"preferred":false,"id":464305,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Gerow, Ken","contributorId":40870,"corporation":false,"usgs":true,"family":"Gerow","given":"Ken","email":"","affiliations":[],"preferred":false,"id":464303,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Landsat data were employed to estimate and characterize land-cover change from 1973, 1980, 1986, 1992, and 2000 using a post-classification comparison. Overall, spatial change was 2.5% (17,830 km<sup>2</sup>). Change increased steadily between 1973 and 1986 but decreased slightly between 1992 and 2000. The grassland/shrubland class, frequently used for livestock grazing, constituted the majority of the study area and had a net decrease from an estimated 83.8% (587,024 km<sup>2</sup>) in 1973 to 82.6% (578,242 km<sup>2</sup>) in 2000. The most common land-use/land-cover conversions across the basin and range ecoregions were indicative of the changes associated with natural, nonmechanical disturbances (i.e., fire), and grassland/shrubland loss to development, agriculture, and mining. This comprehensive look at contemporary land-use/land-cover change provides critical insight into how the deserts of the United States have changed and can be used to inform adaptive management practices of public lands.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Regional Environmental Change","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s10113-012-0296-3","usgsCitation":"Soulard, C.E., and Sleeter, B.M., 2012, Late twentieth century land-cover change in the basin and range ecoregions of the United States: Regional Environmental Change, v. 12, no. 4, p. 813-823, https://doi.org/10.1007/s10113-012-0296-3.","productDescription":"11 p.","startPage":"813","endPage":"823","costCenters":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"links":[{"id":259228,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10113-012-0296-3","linkFileType":{"id":5,"text":"html"}},{"id":259231,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"12","issue":"4","noUsgsAuthors":false,"publicationDate":"2012-03-14","publicationStatus":"PW","scienceBaseUri":"505a4560e4b0c8380cd6727c","contributors":{"authors":[{"text":"Soulard, Christopher E. 0000-0002-5777-9516 csoulard@usgs.gov","orcid":"https://orcid.org/0000-0002-5777-9516","contributorId":2642,"corporation":false,"usgs":true,"family":"Soulard","given":"Christopher","email":"csoulard@usgs.gov","middleInitial":"E.","affiliations":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":462727,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sleeter, Benjamin M. 0000-0003-2371-9571 bsleeter@usgs.gov","orcid":"https://orcid.org/0000-0003-2371-9571","contributorId":3479,"corporation":false,"usgs":true,"family":"Sleeter","given":"Benjamin","email":"bsleeter@usgs.gov","middleInitial":"M.","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true},{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":462728,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
