The chemical structure of organic matter in raw oil shale and spent shale samples was examined in this study using advanced solid-state <sup>13</sup>C nuclear magnetic resonance (NMR) spectroscopy. Oil shale was collected from Mahogany zone outcrops in the Piceance Basin. Five samples were analyzed: (1) raw oil shale, (2) isolated kerogen, (3) oil shale extracted with chloroform, (4) oil shale retorted in an open system at 500°C to mimic surface retorting, and (5) oil shale retorted in a closed system at 360°C to simulate in-situ retorting. The NMR methods applied included quantitative direct polarization with magic-angle spinning at 13 kHz, cross polarization with total sideband suppression, dipolar dephasing, CH<sub>n</sub> selection, <sup>13</sup>C chemical shift anisotropy filtering, and <sup>1</sup>H-<sup>13</sup>C long-range recoupled dipolar dephasing. The NMR results showed that, relative to the raw oil shale, (1) bitumen extraction and kerogen isolation by demineralization removed some oxygen-containing and alkyl moieties; (2) unpyrolyzed samples had low aromatic condensation; (3) oil shale pyrolysis removed aliphatic moieties, leaving behind residues enriched in aromatic carbon; and (4) oil shale retorted in an open system at 500°C contained larger aromatic clusters and more protonated aromatic moieties than oil shale retorted in a closed system at 360°C, which contained more total aromatic carbon with a wide range of cluster sizes.","language":"English","publisher":"AAPG","publisherLocation":"Tulsa, OK","doi":"10.1306/09101211189","usgsCitation":"Cao, X., Birdwell, J.E., Chappell, M.A., Li, Y., Pignatello, J.J., and Mao, J., 2013, Characterization of oil shale, isolated kerogen, and post-pyrolysis residues using advanced 13 solid-state nuclear magnetic resonance spectroscopy: American Association of Petroleum Geologists Bulletin, v. 97, no. 3, p. 421-436, https://doi.org/10.1306/09101211189.","productDescription":"16 p.","startPage":"421","endPage":"436","ipdsId":"IP-034155","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":268711,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"97","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5135c25fe4b03b8ec4025b24","contributors":{"authors":[{"text":"Cao, Xiaoyan","contributorId":86238,"corporation":false,"usgs":true,"family":"Cao","given":"Xiaoyan","affiliations":[],"preferred":false,"id":475355,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Birdwell, Justin E. 0000-0001-8263-1452 jbirdwell@usgs.gov","orcid":"https://orcid.org/0000-0001-8263-1452","contributorId":3302,"corporation":false,"usgs":true,"family":"Birdwell","given":"Justin","email":"jbirdwell@usgs.gov","middleInitial":"E.","affiliations":[{"id":569,"text":"Southwest Climate Science Center","active":true,"usgs":true},{"id":255,"text":"Energy Resources Program","active":true,"usgs":true},{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":475350,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chappell, Mark A.","contributorId":33192,"corporation":false,"usgs":true,"family":"Chappell","given":"Mark","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":475353,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Li, Yuan","contributorId":18241,"corporation":false,"usgs":true,"family":"Li","given":"Yuan","email":"","affiliations":[],"preferred":false,"id":475352,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Pignatello, Joseph J.","contributorId":9143,"corporation":false,"usgs":true,"family":"Pignatello","given":"Joseph","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":475351,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mao, Jingdong","contributorId":79373,"corporation":false,"usgs":true,"family":"Mao","given":"Jingdong","affiliations":[],"preferred":false,"id":475354,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

The existing model was updated using newly collected water-level measurements, inclusion of surface-water features beyond the previous near-field boundary, and refinements to surface-water features. The updated model then was used to calculate the area contributing recharge for seven existing and three proposed pumping locations on lands of the Forest County Potawatomi Community. The existing wells were the subject of a 2004 source-water evaluation in which areas contributing recharge were calculated using the fixed-radius method. The motivation for the present (2012) project was to improve the level of detail of areas contributing recharge for the existing wells and to provide similar analysis for the proposed wells. Delineated 5- and 10-year areas contributing recharge for existing and proposed wells extend from the areas of pumping to delineate the area at the surface contributing recharge to the wells. Steady-state pumping was simulated for two scenarios: a base-pumping scenario using pumping rates that reflect what the Community currently (2012) pumps (or plans to in the case of proposed wells), and a high-pumping scenario in which the rate was set to the maximum expected from wells installed in this area, according to the Forest County Potawatomi Community Natural Resources Department. In general, the 10-year areas contributing recharge did not intersect surface-water bodies. The 5- and 10-year areas contributing recharge simulated at the maximum pumping rate at Bug Lake Road may intersect Bug Lake. At the casino near the Town of Carter, Wisconsin, the 10-year areas contributing recharge intersect infiltration ponds. At the Devils Lake and Lois Crow Drive wells, areas contributing recharge are near cultural features, including residences.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20125289","collaboration":"Prepared in cooperation with the Forest County Potawatomi Community","usgsCitation":"Fienen, M., Saad, D.A., and Juckem, P.F., 2013, Simulation of the shallow groundwater-flow system in the Forest County Potawatomi Community, Forest County, Wisconsin: U.S. Geological Survey Scientific Investigations Report 2012-5289, vi, 24 p., https://doi.org/10.3133/sir20125289.","productDescription":"vi, 24 p.","numberOfPages":"34","onlineOnly":"Y","additionalOnlineFiles":"N","costCenters":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"links":[{"id":268700,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir_2012_5289.gif"},{"id":268698,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2012/5289/"},{"id":268699,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2012/5289/pdf/SIR2012-5289_web.pdf"}],"scale":"100000","country":"United States","state":"Wisconsin","county":"Forest","otherGeospatial":"Forest County Potawatomi Community;Lake Lucerne;Trump Lake;Lake Wabikon;Devils Lake;Lake Metonga","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -89.070282,45.12732 ], [ -89.070282,45.755068 ], [ -88.398743,45.755068 ], [ -88.398743,45.12732 ], [ -89.070282,45.12732 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5135c26be4b03b8ec4025b30","contributors":{"authors":[{"text":"Fienen, Michael N. 0000-0002-7756-4651 mnfienen@usgs.gov","orcid":"https://orcid.org/0000-0002-7756-4651","contributorId":893,"corporation":false,"usgs":true,"family":"Fienen","given":"Michael N.","email":"mnfienen@usgs.gov","affiliations":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"preferred":false,"id":475337,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Saad, David A. dasaad@usgs.gov","contributorId":121,"corporation":false,"usgs":true,"family":"Saad","given":"David","email":"dasaad@usgs.gov","middleInitial":"A.","affiliations":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"preferred":true,"id":475336,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Juckem, Paul F. 0000-0002-3613-1761 pfjuckem@usgs.gov","orcid":"https://orcid.org/0000-0002-3613-1761","contributorId":1905,"corporation":false,"usgs":true,"family":"Juckem","given":"Paul","email":"pfjuckem@usgs.gov","middleInitial":"F.","affiliations":[{"id":37947,"text":"Upper Midwest Water Science Center","active":true,"usgs":true},{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"preferred":true,"id":475338,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

DENs have a dual spatial representation; as points within the network and as points in geographical space. Consequently, some analytical methods used to quantify relationships in other types of ecological networks, or in 2-D space, may be inadequate for studying the influence of structure and connectivity on ecological processes within DENs. We propose a conceptual taxonomy of network analysis methods that account for DEN characteristics to varying degrees and provide a synthesis of the different approaches within\nthe context of stream ecology. Within this context, we summarise the key innovations of a new family of spatial statistical models that describe spatial relationships in DENs. Finally, we discuss how different network analyses may be combined to address more complex and novel research questions. While our main focus is streams, the taxonomy of network analyses is also relevant anywhere spatial patterns in both network and 2-D space can be used to explore the influence of multi-scale processes on biota and their habitat (e.g. plant morphology and pest infestation, or preferential migration along stream or road corridors).","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1111/ele.12084","usgsCitation":"Peterson, E.E., Ver Hoef, J.M., Isaak, D.J., Falke, J.A., Fortin, M., Jordon, C.E., McNyset, K., Monestiez, P., Ruesch, A.S., Sengupta, A., Som, N., Steel, E.A., Theobald, D.M., Torgersen, C., and Wenger, S.J., 2013, Modelling dendritic ecological networks in space: anintegrated network perspective: Ecology Letters, v. 16, no. 5, p. 707-719, https://doi.org/10.1111/ele.12084.","productDescription":"13 p.","startPage":"707","endPage":"719","ipdsId":"IP-043413","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":271343,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":271342,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/ele.12084"}],"volume":"16","issue":"5","noUsgsAuthors":false,"publicationDate":"2013-03-04","publicationStatus":"PW","scienceBaseUri":"51765beae4b0f989f99e00ff","contributors":{"authors":[{"text":"Peterson, Erin E.","contributorId":16264,"corporation":false,"usgs":true,"family":"Peterson","given":"Erin","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":475940,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ver Hoef, Jay M.","contributorId":42504,"corporation":false,"usgs":true,"family":"Ver Hoef","given":"Jay","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":475943,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Isaak, Dan J.","contributorId":59324,"corporation":false,"usgs":true,"family":"Isaak","given":"Dan","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":475947,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Falke, Jeffrey A. 0000-0002-6670-8250 jfalke@usgs.gov","orcid":"https://orcid.org/0000-0002-6670-8250","contributorId":5195,"corporation":false,"usgs":true,"family":"Falke","given":"Jeffrey","email":"jfalke@usgs.gov","middleInitial":"A.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":475936,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fortin, Marie-Josée","contributorId":40462,"corporation":false,"usgs":true,"family":"Fortin","given":"Marie-Josée","affiliations":[],"preferred":false,"id":475942,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Jordon, Chris E.","contributorId":83416,"corporation":false,"usgs":true,"family":"Jordon","given":"Chris","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":475949,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"McNyset, Kristina","contributorId":49255,"corporation":false,"usgs":true,"family":"McNyset","given":"Kristina","email":"","affiliations":[],"preferred":false,"id":475945,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Monestiez, Pascal","contributorId":11910,"corporation":false,"usgs":true,"family":"Monestiez","given":"Pascal","email":"","affiliations":[],"preferred":false,"id":475939,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Ruesch, Aaron S.","contributorId":26559,"corporation":false,"usgs":true,"family":"Ruesch","given":"Aaron","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":475941,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Sengupta, Aritra","contributorId":49256,"corporation":false,"usgs":true,"family":"Sengupta","given":"Aritra","email":"","affiliations":[],"preferred":false,"id":475946,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Som, Nicholas","contributorId":100264,"corporation":false,"usgs":true,"family":"Som","given":"Nicholas","affiliations":[],"preferred":false,"id":475950,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Steel, E.

In addition to circumventing uncertainties associated with labeling natural particles and distinguishing background metals, the proposed \"reverse labeling\" technique overcomes many drawbacks inherent to using radioisotope tracers. Specifically, we chronically exposed freshwater snails (Lymnaea stagnalis) to synthetic water spiked with Cu that was 99.4% <sup>65</sup>Cu to increase the relative abundance of <sup>65</sup>Cu in the snail’s tissues from 32% to >80%. The isotopically enriched snails were then exposed to benthic algae mixed with Cu-bearing Fe–Al particles collected from the Animas River (Colorado), an acid mine drainage impacted river. We used <sup>63</sup>Cu to trace Cu uptake from the natural particles and inferred their bioavailability from calculation of Cu assimilation into tissues. Cu assimilation from these particles was 44%, indicating that 44% of the particulate Cu was absorbed by the invertebrate. This demonstrates that inorganic particulate Cu can be bioavailable. The reverse labeling approach shows great potential in various scientific areas such as environmental contamination and nutrition for addressing questions involving uptake of an element that naturally has multiple isotopes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"ACS Publications (American Chemical Society)","doi":"10.1021/es400162f","usgsCitation":"Croteau, M., Cain, D.J., and Fuller, C.C., 2013, Novel and non-traditional use of stable isotope tracers to study metal bioavailability from natural particles: Environmental Science & Technology, v. 47, no. 7, p. 3424-3431, https://doi.org/10.1021/es400162f.","productDescription":"8 p.","startPage":"3424","endPage":"3431","numberOfPages":"8","ipdsId":"IP-044147","costCenters":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"links":[{"id":271606,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":271605,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es400162f"}],"volume":"47","issue":"7","noUsgsAuthors":false,"publicationDate":"2013-03-18","publicationStatus":"PW","scienceBaseUri":"517f966ce4b0e41721f7a377","contributors":{"authors":[{"text":"Croteau, Marie-Noële","contributorId":22863,"corporation":false,"usgs":true,"family":"Croteau","given":"Marie-Noële","affiliations":[],"preferred":false,"id":476329,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cain, Daniel J. 0000-0002-3443-0493 djcain@usgs.gov","orcid":"https://orcid.org/0000-0002-3443-0493","contributorId":1784,"corporation":false,"usgs":true,"family":"Cain","given":"Daniel","email":"djcain@usgs.gov","middleInitial":"J.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":476327,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fuller, Christopher C. 0000-0002-2354-8074 ccfuller@usgs.gov","orcid":"https://orcid.org/0000-0002-2354-8074","contributorId":1831,"corporation":false,"usgs":true,"family":"Fuller","given":"Christopher","email":"ccfuller@usgs.gov","middleInitial":"C.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":374,"text":"Maryland Water Science Center","active":true,"usgs":true},{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":36183,"text":"Hydro-Ecological Interactions Branch","active":true,"usgs":true}],"preferred":true,"id":476328,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Each data set helps resolve ambiguities in interpreting the other. In addition, gravity data can be used to infer the sense of motion for totally buried faults inferred solely from aeromagnetic data. Combined interpretation to identify active faults at the northern end of the San Luis Basin of the northern Rio Grande rift has confirmed general aspects of previous geologic mapping but has also provided significant improvements.

Historical topography was generated from digital stereo-photogrammetry and compared with more recent lidar surveys to quantify near-term (decadal) morphodynamic changes to the beach and primary dune system between the years 1969, 1999, and 2009. Notably increased profile volumes were observed along the entirety of the island in 1999, and likely provide the eolian source for the steady dune crest progradation observed over the relatively quiescent decade that followed. Persistent patterns of erosion and accretion over 10-, 30-, and 40-year intervals are attributable to variations in island morphology, human activity, and variations in offshore bathymetry and island orientation that influence the wave energy reaching the coast. Areas of documented long-term historical inlet formation and extensive bayside marsh development show substantial landward translation of the dune–beach profile over the near-term period of this study. Correlations among areas predicted to overwash, observed elevation changes of the dune crestline, and observed instances of overwash in undeveloped segments of the barrier island verify that overwash locations can be accurately predicted in undeveloped segments of coast. In fact, an assessment of 2012 aerial imagery collected after Hurricane Sandy confirms that overwash occurred at the majority of near-term locations persistently predicted to overwash. In addition to the storm wave climate, factors related to variations within the geologic framework which in turn influence island orientation, offshore slope, and sediment supply impact island behavior on near-term timescales.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.margeo.2013.02.004","usgsCitation":"Lentz, E., Hapke, C.J., Stockdon, H.F., and Hehre, R.E., 2013, Improving understanding of near-term barrier island evolution through multi-decadal assessment of morphologic change: Marine Geology, v. 337, p. 125-139, https://doi.org/10.1016/j.margeo.2013.02.004.","productDescription":"15 p.","startPage":"125","endPage":"139","numberOfPages":"15","ipdsId":"IP-037688","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":473925,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://hdl.handle.net/1912/6111","text":"External Repository"},{"id":288096,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":288094,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.margeo.2013.02.004"}],"country":"United States","state":"New York","otherGeospatial":"Fire Island","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -73.35022,40.499181 ], [ -73.35022,40.849138 ], [ -72.70134,40.849138 ], [ -72.70134,40.499181 ], [ -73.35022,40.499181 ] ] ] } } ] }","volume":"337","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53903ff0e4b04eea98bf8521","chorus":{"doi":"10.1016/j.margeo.2013.02.004","url":"http://dx.doi.org/10.1016/j.margeo.2013.02.004","publisher":"Elsevier BV","authors":"Lentz Erika E., Hapke Cheryl J., Stockdon Hilary F., Hehre Rachel E.","journalName":"Marine Geology","publicationDate":"3/2013"},"contributors":{"authors":[{"text":"Lentz, Erika E.","contributorId":105375,"corporation":false,"usgs":true,"family":"Lentz","given":"Erika E.","affiliations":[],"preferred":false,"id":494364,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hapke, Cheryl J. 0000-0002-2753-4075 chapke@usgs.gov","orcid":"https://orcid.org/0000-0002-2753-4075","contributorId":2981,"corporation":false,"usgs":true,"family":"Hapke","given":"Cheryl","email":"chapke@usgs.gov","middleInitial":"J.","affiliations":[{"id":6676,"text":"USGS (retired)","active":true,"usgs":false}],"preferred":true,"id":494362,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stockdon, Hilary F. 0000-0003-0791-4676 hstockdon@usgs.gov","orcid":"https://orcid.org/0000-0003-0791-4676","contributorId":2153,"corporation":false,"usgs":true,"family":"Stockdon","given":"Hilary","email":"hstockdon@usgs.gov","middleInitial":"F.","affiliations":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true},{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":true,"id":494361,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hehre, Rachel E.","contributorId":93390,"corporation":false,"usgs":true,"family":"Hehre","given":"Rachel","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":494363,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

However, little is known about the relationships between Spotted Owl survival and home-range size and the characteristics of fire-prone, mixed-conifer forests of the Klamath province. Thus, the objectives of this study were to estimate monthly survival rates and home-range size in relation to habitat characteristics for Northern Spotted Owls in southwestern Oregon. Home-range size and survival of 15 Northern Spotted Owls was monitored using radiotelemetry in the Ashland Ranger District of the Rogue River–Siskiyou National Forest from September 2006 to October 2008. Habitat classes within Spotted Owl home ranges were characterized using a remote-sensed vegetation map of the study area. Estimates of monthly survival ranged from 0.89 to 1.0 and were positively correlated with the number of late-seral habitat patches and the amount of edge, and negatively correlated with the mean nearest neighbor distance between late-seral habitats. Annual home-range size varied from to 189 to 894 ha ( x =  576; SE  =  75), with little difference between breeding and nonbreeding home ranges. Breeding-season home-range size increased with the amount of hard edge, and the amount of old and mature forest combined. Core area, annual and nonbreeding season home-range sizes all increased with increased amounts of hard edge, suggesting that increased fragmentation is associated with larger core and home-range sizes. Although no effect of the amount of late-seral stage forest on either survival or home-range size was detected, these results are the first to concurrently demonstrate increased forest fragmentation with decreased survival and increased home-range size of Northern Spotted Owls.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Raptor Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Raptor Research Foundation","doi":"10.3356/JRR-11-76.1","usgsCitation":"Schilling, J., Dugger, K.M., and Anthony, R., 2013, Survival and home-range size of Northern Spotted Owls in southwestern Oregon: Journal of Raptor Research, v. 47, no. 1, p. 1-14, https://doi.org/10.3356/JRR-11-76.1.","productDescription":"14 p.","startPage":"1","endPage":"14","numberOfPages":"14","ipdsId":"IP-036945","costCenters":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"links":[{"id":473926,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3356/jrr-11-76.1","text":"Publisher Index Page"},{"id":276919,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":276917,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3356/JRR-11-76.1"}],"country":"United States","state":"Oregon","county":"Jackson County;Klamath County;Lake County","otherGeospatial":"Klamath Province","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.4131,42.0031 ], [ -122.4131,43.2331 ], [ -120.1835,43.2331 ], [ -120.1835,42.0031 ], [ -122.4131,42.0031 ] ] ] } } ] }","volume":"47","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"521732e8e4b043bae8d2e621","contributors":{"authors":[{"text":"Schilling, Jason W.","contributorId":71469,"corporation":false,"usgs":true,"family":"Schilling","given":"Jason W.","affiliations":[],"preferred":false,"id":468667,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dugger, Katie M. 0000-0002-4148-246X","orcid":"https://orcid.org/0000-0002-4148-246X","contributorId":36037,"corporation":false,"usgs":true,"family":"Dugger","given":"Katie","email":"","middleInitial":"M.","affiliations":[{"id":517,"text":"Oregon Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"preferred":false,"id":468665,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Anthony, Robert G.","contributorId":61324,"corporation":false,"usgs":true,"family":"Anthony","given":"Robert G.","affiliations":[],"preferred":false,"id":468666,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Such flows are among the most serious ground-based hazards at many volcanoes because of their sudden onset, rapid advance rates, long runout distances, high energy, ability to transport large volumes of material, and tendency to flow along existing river channels where populations and infrastructure are commonly concentrated. They can grow in volume and peak discharge through erosion and incorporation of external sediment and/or water, inundate broad areas, and leave deposits many meters thick. Furthermore, lahars can recur for many years to decades after an initial volcanic eruption, as fresh pyroclastic material is eroded and redeposited during rainfall events, resulting in a spatially and temporally evolving hazard. Improving understanding of the behavior of these complex, gravitationally driven, multi-phase flows is key to mitigating the threat to communities at lahar-prone volcanoes. However, their complexity and evolving nature pose significant challenges to developing the models of flow behavior required for delineating their hazards and hazard zones.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Modeling volcanic processes: the physics and mathematics of volcanism","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Cambridge University Press","publisherLocation":"Cambridge","doi":"10.1017/CBO9781139021562.014","isbn":"9781139021562; 9780521895439","usgsCitation":"Manville, V., Major, J.J., and Fagents, S.A., 2013, Modeling lahar behavior and hazards, chap. <i>of</i> Modeling volcanic processes: the physics and mathematics of volcanism, p. 300-330, https://doi.org/10.1017/CBO9781139021562.014.","productDescription":"31 p.","startPage":"300","endPage":"330","numberOfPages":"31","ipdsId":"IP-035264","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":275639,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":275638,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1017/CBO9781139021562.014"}],"country":"United States","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51fa31e5e4b076c3a8d8265a","contributors":{"authors":[{"text":"Manville, Vernon","contributorId":70272,"corporation":false,"usgs":true,"family":"Manville","given":"Vernon","email":"","affiliations":[],"preferred":false,"id":478035,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Major, Jon J. 0000-0003-2449-4466 jjmajor@usgs.gov","orcid":"https://orcid.org/0000-0003-2449-4466","contributorId":439,"corporation":false,"usgs":true,"family":"Major","given":"Jon","email":"jjmajor@usgs.gov","middleInitial":"J.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":478033,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fagents, Sarah A.","contributorId":66152,"corporation":false,"usgs":true,"family":"Fagents","given":"Sarah","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":478034,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

A relatively recent development is the combination of species distribution models, land‐use change predictions, and dynamic population models to predict the relative and combined impacts of climate change, land‐use change, and altered disturbance regimes on species' extinction risk. Each modelling component introduces its own source of uncertainty through different parameters and assumptions, which, when combined, can result in compounded uncertainty that can have major implications for management. Although some uncertainty analyses have been conducted separately on various model components – such as climate predictions, species distribution models, land‐use change predictions, and population models – a unified sensitivity analysis comparing various sources of uncertainty in combined modelling approaches is needed to identify the most influential and problematic assumptions. We estimated the sensitivities of long‐run population predictions to different ecological assumptions and parameter settings for a rare and endangered annual plant species (</span><i>Acanthomintha ilicifolia</i><span>, or San Diego thornmint).

To better understand stresses generated by specific processes and events, many coral reef scientists seek to collect physical samples of settling particles and obtain reproducible information about net rates of sediment accumulation on coral reefs. Yet, the tools most commonly used to gather this information, sediment tube traps, only provide information on the gross accumulation of sediment at a site, in that all particles are effectively trapped within the container, unlike what a coral surface experiences. To address the need for an improved measurement of net particle accumulation on coral surfaces, we propose using recoverable sediment pods (SedPods) that can be constructed from readily available materials for under US $20. These devices are inexpensive, easy to fabricate, and allow for capture of particles over a given time span. The particles can then be used for laboratory analysis and accurate calculation of net accumulation rates on a coral surface proxy. In an experiment in Hanalei Bay, HI, we found that net sediment accumulation on rectangular SedPods was an order of magnitude less than gross accumulation in nearby conventional tube traps.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s00338-012-0953-5","usgsCitation":"Field, M.E., Chezar, H., and Storlazzi, C.D., 2013, SedPods: a low-cost coral proxy for measuring net sedimentation: Coral Reefs, v. 32, no. 1, p. 155-159, https://doi.org/10.1007/s00338-012-0953-5.","productDescription":"5 p.","startPage":"155","endPage":"159","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":358211,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"32","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-09-12","publicationStatus":"PW","scienceBaseUri":"5c10ba93e4b034bf6a7ee119","contributors":{"authors":[{"text":"Field, Michael E. mfield@usgs.gov","contributorId":2101,"corporation":false,"usgs":true,"family":"Field","given":"Michael","email":"mfield@usgs.gov","middleInitial":"E.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":747543,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Chezar, Henry hchezar@usgs.gov","contributorId":2964,"corporation":false,"usgs":true,"family":"Chezar","given":"Henry","email":"hchezar@usgs.gov","affiliations":[],"preferred":true,"id":747544,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Storlazzi, Curt D. 0000-0001-8057-4490 cstorlazzi@usgs.gov","orcid":"https://orcid.org/0000-0001-8057-4490","contributorId":140584,"corporation":false,"usgs":true,"family":"Storlazzi","given":"Curt","email":"cstorlazzi@usgs.gov","middleInitial":"D.","affiliations":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":747545,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Patches of dead ʻŌhiʻa stands had been reported from the windward slopes of Mauna Loa and Mauna Kea.

A common strategy for acquiring such information is to drill sentinel wells near the coast to monitor changes in water salinity with time. However, installation and operation of sentinel wells is costly and provides limited spatial coverage. We studied the use of noninvasive electromagnetic (EM) geophysical methods as an alternative to installation of monitoring wells for characterizing coastal aquifers. We tested the feasibility of using EM methods at a field site in northern California to identify the potential for and/or presence of hydraulic communication between an unconfined saline aquifer and a confined freshwater aquifer. One-dimensional soundings were acquired using the time-domain electromagnetic (TDEM) and audiomagnetotelluric (AMT) methods. We compared inverted resistivity models of TDEM and AMT data obtained from several inversion algorithms. We found that multiple interpretations of inverted models can be supported by the same data set, but that there were consistencies between all data sets and inversion algorithms. Results from all collected data sets suggested that EM methods are capable of reliably identifying a saltwater-saturated zone in the unconfined aquifer.

Since low <i>b</i>-values represent high differential stresses, the asperity structure seems to be always stably stressed and even unaffected by the latest main shock in 2004. However, because fault loading rates and applied shear stress vary with time, some degree of temporal variability of the <i>b</i>-value within stable blocks is to be expected. We discuss in this study adequate techniques and uncertainty treatment for a detailed analysis of the temporal evolution of <i>b</i>-values. We show that the derived signal for the Parkfield asperity correlates with changes in surface creep, suggesting a sensitive time resolution of the b-value stress meter, and confirming near-critical loading conditions within the Parkfield asperity.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geophysical Journal International","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Royal Astronomical Society","doi":"10.1093/gji/ggt093","usgsCitation":"Tormann, T., Wiemer, S., Metzger, S., Michael, A.J., and Hardebeck, J.L., 2013, Size distribution of Parkfield’s microearthquakes reflects changes in surface creep rate: Geophysical Journal International, v. 193, no. 3, p. 1474-1478, https://doi.org/10.1093/gji/ggt093.","productDescription":"5 p.","startPage":"1474","endPage":"1478","numberOfPages":"5","ipdsId":"IP-044643","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":473928,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://gfzpublic.gfz-potsdam.de/pubman/item/item_328088","text":"External Repository"},{"id":275714,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":275660,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1093/gji/ggt093"},{"id":275661,"type":{"id":15,"text":"Index Page"},"url":"https://gji.oxfordjournals.org/content/193/3/1474"}],"volume":"193","issue":"3","noUsgsAuthors":false,"publicationDate":"2013-03-28","publicationStatus":"PW","scienceBaseUri":"51fbca81e4b04b00e3d890f9","contributors":{"authors":[{"text":"Tormann, Theresa","contributorId":55713,"corporation":false,"usgs":true,"family":"Tormann","given":"Theresa","email":"","affiliations":[],"preferred":false,"id":481729,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wiemer, Stefan","contributorId":81566,"corporation":false,"usgs":true,"family":"Wiemer","given":"Stefan","affiliations":[],"preferred":false,"id":481731,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Metzger, Sabrina","contributorId":76205,"corporation":false,"usgs":true,"family":"Metzger","given":"Sabrina","email":"","affiliations":[],"preferred":false,"id":481730,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Michael, Andrew J. 0000-0002-2403-5019 michael@usgs.gov","orcid":"https://orcid.org/0000-0002-2403-5019","contributorId":1280,"corporation":false,"usgs":true,"family":"Michael","given":"Andrew","email":"michael@usgs.gov","middleInitial":"J.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":234,"text":"Earthquake Hazards Program","active":true,"usgs":true}],"preferred":true,"id":481728,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hardebeck, Jeanne L. 0000-0002-6737-7780 jhardebeck@usgs.gov","orcid":"https://orcid.org/0000-0002-6737-7780","contributorId":841,"corporation":false,"usgs":true,"family":"Hardebeck","given":"Jeanne","email":"jhardebeck@usgs.gov","middleInitial":"L.","affiliations":[{"id":234,"text":"Earthquake Hazards Program","active":true,"usgs":true},{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":481727,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The growing interest in managing dead woody material has created strong demand for greater understanding of factors controlling amounts and turnover. Prescribed burning, an important management tool, may have strong effects of dead woody material given fire&rsquo;s capacity to create and consume dead woody material. We determined effects of long-term understory prescribed burning on standing and down woody material in upland oak forests in south-central North America. We hypothesized that as frequency of fire increased in these stands the amount of deadwood would decrease and the fine woody material would decrease more rapidly than coarse woody material. The study was conducted in forests dominated by post oak (<i>Quercus stellata</i>) and blackjack oak (<i>Quercus marilandica</i>) in wildlife management areas where understory prescribed burning had been practiced for over 20 years and the range of burn frequencies was 0 (unburned) fires per decade (FPD) to 4.6 FPD. The amount of deadwood was low compared with more productive forests in southeastern North America. The biomass (24.7 Mg ha<sup>-1</sup>) and carbon stocks (11.7 Mg ha<sup>-1</sup>) were distributed among standing dead (22%), coarse woody debris (CWD, dia. &gt; 7.5 cm., 12%), fine woody debris (FWD, dia. &lt; 7.5 cm., 23%), and forest floor (43%). There was no evidence that understory prescribed burning influenced the amount and size distribution of standing and down dead woody material. There were two explanations for the lack of a detectable effect. First, a high incidence of severe weather including ice storms and strong winds that produce large amounts of deadwood intermittently in an irregular pattern across the landscape may preclude detecting a strong effect of understory prescribed burning. Second, fire suppression during the first one-half of the 20th Century may have led to encroachment of woody plants into forest gaps and savannas creating a patchwork of young and old stands that produced deadwood of different sizes and at different rates.</p>","language":"English","publisher":"Elsevier Science","publisherLocation":"Amsterdam","doi":"10.1016/j.foreco.2012.10.048","collaboration":"Oklahoma Department of Wildlife Conservation; Oklahoma State University","usgsCitation":"Polo, J.A., Hallgren, S., and Leslie, D.M., 2013, Effect of long-term understory prescribed burning on standing and down dead woody material in dry upland oak forests: Forest Ecology and Management, v. 291, p. 128-135, https://doi.org/10.1016/j.foreco.2012.10.048.","productDescription":"8 p.","startPage":"128","endPage":"135","numberOfPages":"8","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-039145","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":301511,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"291","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"558931b9e4b0b6d21dd61bd1","chorus":{"doi":"10.1016/j.foreco.2012.10.048","url":"http://dx.doi.org/10.1016/j.foreco.2012.10.048","publisher":"Elsevier BV","authors":"Polo John A., Hallgren Stephen W., Leslie David M.","journalName":"Forest Ecology and Management","publicationDate":"3/2013","auditedOn":"11/1/2014"},"contributors":{"authors":[{"text":"Polo, John A.","contributorId":141527,"corporation":false,"usgs":false,"family":"Polo","given":"John","email":"","middleInitial":"A.","affiliations":[{"id":7249,"text":"Oklahoma State University","active":true,"usgs":false}],"preferred":false,"id":549771,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hallgren, S.W.","contributorId":97742,"corporation":false,"usgs":true,"family":"Hallgren","given":"S.W.","email":"","affiliations":[],"preferred":false,"id":549772,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Leslie, David M.

Meeting the ISCCP goals of global coverage and decade-length time scales requires consistent and stable calibration of the participating satellites. For the geostationary imager visible channels, ISCCP calibration provides regular periodic updates from regressions of radiances measured from coincident and collocated observations taken by Advanced Very High Resolution Radiometer instruments. As an independent check of the temporal stability and intersatellite consistency of ISCCP calibrations, we have applied lunar calibration techniques to geostationary imager visible channels using images of the Moon found in the ISCCP data archive. Lunar calibration enables using the reflected light from the Moon as a stable and consistent radiometric reference. Although the technique has general applicability, limitations of the archived image data have restricted the current study to Geostationary Operational Environmental Satellite and Geostationary Meteorological Satellite series. The results of this lunar analysis confirm that ISCCP calibration exhibits negligible temporal trends in sensor response but have revealed apparent relative biases between the satellites at various levels. However, these biases amount to differences of only a few percent in measured absolute reflectances. Since the lunar analysis examines only the lower end of the radiance range, the results suggest that the ISCCP calibration regression approach does not precisely determine the intercept or the zero-radiance response level. We discuss the impact of these findings on the development of consistent calibration for multisatellite global data sets.</p>","language":"English","publisher":"Institute of Electrical and Electronics Engineers","publisherLocation":"New York, NY","doi":"10.1109/TGRS.2012.2237520","usgsCitation":"Stone, T., Rossow, W.B., Ferrier, J., and Hinkelman, L.M., 2013, Evaluation of ISCCP multisatellite radiance calibration for geostationary imager visible channels using the moon: IEEE Transactions on Geoscience and Remote Sensing, v. 51, no. 3, p. 1255-1266, https://doi.org/10.1109/TGRS.2012.2237520.","productDescription":"12 p.","startPage":"1255","endPage":"1266","numberOfPages":"12","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-035504","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":473929,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1109/tgrs.2012.2237520","text":"Publisher Index Page"},{"id":305953,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"51","issue":"3","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55b361afe4b09a3b01b5da99","contributors":{"authors":[{"text":"Stone, Thomas C. tstone@usgs.gov","contributorId":3176,"corporation":false,"usgs":true,"family":"Stone","given":"Thomas C.","email":"tstone@usgs.gov","affiliations":[],"preferred":true,"id":564741,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rossow, William B.","contributorId":145601,"corporation":false,"usgs":false,"family":"Rossow","given":"William","email":"","middleInitial":"B.","affiliations":[{"id":590,"text":"U.S. Army Corps of Engineers","active":false,"usgs":false}],"preferred":false,"id":564744,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Ferrier, Joseph","contributorId":145599,"corporation":false,"usgs":false,"family":"Ferrier","given":"Joseph","email":"","affiliations":[{"id":590,"text":"U.S. Army Corps of Engineers","active":false,"usgs":false}],"preferred":false,"id":564742,"contributorType":{"id":1,"text":"Authors"},"rank":12},{"text":"Hinkelman, Laura M.","contributorId":145600,"corporation":false,"usgs":false,"family":"Hinkelman","given":"Laura","email":"","middleInitial":"M.","affiliations":[{"id":590,"text":"U.S. Army Corps of Engineers","active":false,"usgs":false}],"preferred":false,"id":564743,"contributorType":{"id":1,"text":"Authors"},"rank":13}]}}

Stream segments (N=13) with similar landscape characters were classified by SF volume into high SF (HSF) or low SF (LSF) groups. The densities of smallmouth bass, channel unit (CU) use and temperature-selection patterns were assessed for several life stages and frequency distributions for age 0 fish. More smallmouth bass were present in stream segments with HSF influence. Age 0 fish were twice as likely to be present in HSF stream segments. Older age classes were present in stream reaches independent of SF contribution. For all age classes, the use of particular CUs did not depend on SF influence. All age classes were more likely to be present in pools than other CUs. Microhabitat temperature selection differed among age classes. Age 0 fish selected warmer temperatures with a gradual shift towards cooler temperatures for older age classes. The length frequency of age 0 fish was skewed towards larger individuals in streams with limited SF influence, whereas the length frequency in HSF stream segments was skewed towards smaller individuals. The benefits of significant groundwater via SF influence seem to be related to increased hatch or survival of age 0 fish and the availability of optimal temperatures for adult smallmouth bass growth. Thermal refugia and stable flows provided by springs should be recognised for their biological potential to provide suitable habitat as climate change and other land-use alterations increase temperature regimes and alter flow patterns.</p>","language":"English","publisher":"John Wiley & Sons","publisherLocation":"Chichester, West Sussex, UK","doi":"10.1002/rra.1595","usgsCitation":"Brewer, S.K., 2013, Groundwater influences on the distribution and abundance of riverine smallmouth bass, <i>Micropterus dolomieu</i>, in pasture landscapes of the midwestern USA: River Research and Applications, v. 29, no. 3, p. 269-278, https://doi.org/10.1002/rra.1595.","productDescription":"10 p.","startPage":"269","endPage":"278","numberOfPages":"10","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-026302","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":300276,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"3","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationDate":"2011-09-20","publicationStatus":"PW","scienceBaseUri":"5551d2b4e4b0a92fa7e93be7","contributors":{"authors":[{"text":"Brewer, Shannon K. 0000-0002-1537-3921 skbrewer@usgs.gov","orcid":"https://orcid.org/0000-0002-1537-3921","contributorId":2252,"corporation":false,"usgs":true,"family":"Brewer","given":"Shannon","email":"skbrewer@usgs.gov","middleInitial":"K.","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true},{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":546440,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

As a result, both water and air reached the sulfide deposits deep within the mountain, producing acid mine drainage consisting of sulfuric acid and heavy metals from the ore. Particularly, the drainage water from the Richmond Mine at Iron Mountain is among the most acidic waters naturally found on Earth. The mineralogy at Iron Mountain can serve as a proxy for understanding sulfate formation on Mars. Selected sulfate efflorescent salts from Iron Mountain, formed from extremely acidic waters via drainage from sulfide mining, have been characterized by means of Raman spectroscopy. Gypsum, ferricopiapite, copiapite, melanterite, coquimbite, and voltaite are found within the samples.

Because amphibian reproduction is tightly associated with the presence of water, climatic changes that affect water availability pose a particularly menacing threat to both aquatic and terrestrial-breeding amphibians. We explore the impacts that one facet of climate change—that of extreme variation in precipitation—may have on amphibians. This variation is manifested principally as increases in the incidence and severity of both drought and major storm events. We stress the need to consider not only total precipitation amounts but also the pattern and timing of rainfall events. Such rainfall “pulses” are likely to become increasingly more influential on amphibians, especially in relation to seasonal reproduction. Changes in reproductive phenology can strongly influence the outcome of competitive and predatory interactions, thus potentially altering community dynamics in assemblages of co-existing species. We present a conceptual model to illustrate possible landscape and metapopulation consequences of alternative climate change scenarios for pond-breeding amphibians, using the Mole Salamander, <i>Ambystoma talpoideum</i>, as an example. Although amphibians have evolved a variety of life history strategies that enable them to cope with environmental uncertainty, it is unclear whether adaptations can keep pace with the escalating rate of climate change. Climate change, especially in combination with other stressors, is a daunting challenge for the persistence of amphibians and, thus, the conservation of global biodiversity.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"MDPI AG","publisherLocation":"Basel, Switzerland","doi":"10.3390/biology2010399","usgsCitation":"Walls, S., Barichivich, W.J., and Brown, M.E., 2013, Drought, deluge and declines: the impact of precipitation extremes on amphibians in a changing climate: Biology, v. 2, no. 1, p. 399-418, https://doi.org/10.3390/biology2010399.","productDescription":"20 p.","startPage":"399","endPage":"418","numberOfPages":"20","ipdsId":"IP-041780","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":473931,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3390/biology2010399","text":"Publisher Index Page"},{"id":277187,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":277186,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3390/biology2010399"}],"volume":"2","issue":"1","noUsgsAuthors":false,"publicationDate":"2013-03-11","publicationStatus":"PW","scienceBaseUri":"5221bee2e4b001cbb8a34ee0","contributors":{"authors":[{"text":"Walls, Susan C. 0000-0001-7391-9155","orcid":"https://orcid.org/0000-0001-7391-9155","contributorId":52284,"corporation":false,"usgs":true,"family":"Walls","given":"Susan C.","affiliations":[],"preferred":false,"id":483264,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barichivich, William J. 0000-0003-1103-6861 wbarichivich@usgs.gov","orcid":"https://orcid.org/0000-0003-1103-6861","contributorId":3697,"corporation":false,"usgs":true,"family":"Barichivich","given":"William","email":"wbarichivich@usgs.gov","middleInitial":"J.","affiliations":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true},{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"preferred":true,"id":483262,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brown, Mary E. 0000-0002-5580-137X mbrown@usgs.gov","orcid":"https://orcid.org/0000-0002-5580-137X","contributorId":5688,"corporation":false,"usgs":true,"family":"Brown","given":"Mary","email":"mbrown@usgs.gov","middleInitial":"E.","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":483263,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Mean anaerobic CO<sub>2</sub> production potential at 10 cm depth (14.1 ± 0.9 μmol C g<sup>−1</sup> d<sup>−1</sup>) was as high as aerobic CO<sub>2</sub> production potential (10.6 ± 1.5 μmol C g<sup>−1</sup> d<sup>−1</sup>), while CH4 production was low (mean of 7.8 ± 1.5 nmol C g<sup>−1</sup> d<sup>−1</sup>). Denitrification enzyme activity indicated a very high denitrification potential (197 ± 23 μg N g<sup>−1</sup> d<sup>−1</sup>), but net NO<sup>-</sup><sub>3</sub> reduction suggested this was a relatively minor pathway for anaerobic CO<sub>2</sub> production. Abundances of denitrifier genes (<i>nirK</i> and <i>nosZ</i>) did not change across water table treatments. SO<sup>2-</sup><sub>4</sub> reduction also did not appear to be an important pathway for anaerobic CO<sub>2</sub> production. The net accumulation of acetate and formate as decomposition end products in the raised water table treatment suggested that fermentation was a significant pathway for carbon mineralization, even in the presence of NO<sup>-</sup><sub>3</sub>. Dissolved organic carbon (DOC) concentrations were the strongest predictors of potential anaerobic and aerobic CO<sub>2</sub> production. Across all water table treatments, the CO<sub>2</sub>:CH<sub>4</sub> ratio increased with initial DOC leachate concentrations. While the field water table treatment did not have a significant effect on mean CO<sub>2</sub> or CH<sub>4</sub> production potential, the CO<sub>2</sub>:CH<sub>4</sub> ratio was highest in shallow peat incubations from the drained treatment. These data suggest that with continued drying or with a more variable water table, anaerobic CO<sub>2</sub> production may be favored over CH<sub>4</sub> production in this rich fen. Future research examining the potential for dissolved organic substances to facilitate anaerobic respiration, or alternative redox processes that limit the effectiveness of organic acids as substrates in anaerobic metabolism, would help explain additional uncertainty concerning carbon mineralization in this system.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Soil Biology and Biochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Pergamon","publisherLocation":"Oxford","doi":"10.1016/j.soilbio.2012.10.032","usgsCitation":"Kane, E., Chivers, M., Turetsky, M., Treat, C.C., Petersen, D., Waldrop, M., Harden, J., and McGuire, A., 2013, Response of anaerobic carbon cycling to water table manipulation in an Alaskan rich fen: Soil Biology and Biochemistry, v. 58, p. 50-60, https://doi.org/10.1016/j.soilbio.2012.10.032.","productDescription":"11 p.","startPage":"50","endPage":"60","numberOfPages":"11","costCenters":[],"links":[{"id":291110,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291109,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.soilbio.2012.10.032"}],"volume":"58","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57f7f346e4b0bc0bec0a08ac","contributors":{"authors":[{"text":"Kane, E.S.","contributorId":42275,"corporation":false,"usgs":true,"family":"Kane","given":"E.S.","email":"","affiliations":[],"preferred":false,"id":496615,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Chivers, M.R.","contributorId":96505,"corporation":false,"usgs":true,"family":"Chivers","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":496616,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Turetsky, M.R.","contributorId":107470,"corporation":false,"usgs":true,"family":"Turetsky","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":496619,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Treat, Claire C.","contributorId":96606,"corporation":false,"usgs":true,"family":"Treat","given":"Claire","email":"","middleInitial":"C.","affiliations":[{"id":25501,"text":"University of Eastern Finland","active":true,"usgs":false}],"preferred":false,"id":496617,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Petersen, D.G.","contributorId":31687,"corporation":false,"usgs":true,"family":"Petersen","given":"D.G.","email":"","affiliations":[],"preferred":false,"id":496613,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Waldrop, M.","contributorId":97436,"corporation":false,"usgs":true,"family":"Waldrop","given":"M.","email":"","affiliations":[],"preferred":false,"id":496618,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Harden, J.W. 0000-0002-6570-8259","orcid":"https://orcid.org/0000-0002-6570-8259","contributorId":38585,"corporation":false,"usgs":true,"family":"Harden","given":"J.W.","affiliations":[],"preferred":false,"id":496614,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"McGuire, A.
