We employed a hybrid supervised and unsupervised image classification technique on a total of 128 Landsat scenes gathered between 1999 and 2004, and validated the results using existing geographic information science (GIS) datasets, high resolution imagery, and published literature. We also draw a comparative analysis with the mangrove forests inventory published by the Food and Agriculture Association (FAO) of the United Nations. Our estimate shows a total of 623755 hectares of mangrove forests in the Pacific region; an increase of 18% from FAO's estimates.

Habitat suitability modeling provides a tool for researchers and managers to understand the potential extent of invasive species spread. Our goal was to use habitat suitability modeling to map potential habitat of the riparian plant invader, Russian olive (<i>Elaeagnus angustifolia</i>). Russian olive has invaded riparian habitat across North America and is continuing to expand its range. We compiled 11 disparate datasets for Russian olive presence locations (n = 1,051 points and 139 polygons) in the western US and used Maximum entropy (Maxent) modeling to develop two habitat suitability maps for Russian olive in the western United States: one with coarse-scale water data and one with fine-scale water data. Our models were able to accurately predict current suitable Russian olive habitat (Coarse model: training AUC = 0.938, test AUC = 0.907; Fine model: training AUC = 0.923, test AUC = 0.885). Distance to water was the most important predictor for Russian olive presence in our coarse-scale water model, but it was only the fifth most important variable in the fine-scale model, suggesting that when water bodies are considered on a fine scale, Russian olive does not necessarily rely on water. Our model predicted that Russian olive has suitable habitat further west from its current distribution, expanding into the west coast and central North America. Our methodology proves useful for identifying potential future areas of invasion. Model results may be influenced by locations of cultivated individuals and sampling bias. Further study is needed to examine the potential for Russian olive to invade beyond its current range. Habitat suitability modeling provides an essential tool for enhancing our understanding of invasive species spread.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Invasions","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Kluwer Academic Publishers","publisherLocation":"Dordrecht","doi":"10.1007/s10530-010-9798-4","usgsCitation":"Jarnevich, C.S., and Reynolds, L., 2011, Challenges of predicting the potential distribution of a slow-spreading invader: a habitat suitability map for an invasive riparian tree: Biological Invasions, v. 13, no. 1, p. 153-163, https://doi.org/10.1007/s10530-010-9798-4.","productDescription":"11 p.","startPage":"153","endPage":"163","numberOfPages":"11","costCenters":[],"links":[{"id":291359,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291358,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10530-010-9798-4"}],"volume":"13","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-07-02","publicationStatus":"PW","scienceBaseUri":"57fe7fb6e4b0824b2d1478f8","contributors":{"authors":[{"text":"Jarnevich, Catherine S. 0000-0002-9699-2336 jarnevichc@usgs.gov","orcid":"https://orcid.org/0000-0002-9699-2336","contributorId":3424,"corporation":false,"usgs":true,"family":"Jarnevich","given":"Catherine","email":"jarnevichc@usgs.gov","middleInitial":"S.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":497151,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reynolds, Lindsay V.","contributorId":102732,"corporation":false,"usgs":true,"family":"Reynolds","given":"Lindsay V.","affiliations":[],"preferred":false,"id":497152,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

In retrospect, the first earthquakes in the swarm were detected about 1 month prior to the eruption onset. Activity in the swarm quickly intensified less than 48 h prior to the first large explosion and subsequently subsided with decline of eruptive activity. The largest earthquake measured as moment magnitude 5.8, and a dozen additional earthquakes were larger than magnitude 4. The swarm exhibited both tectonic and volcanic characteristics. Its shear failure earthquake features were <i>b</i> value = 0.9, most earthquakes with impulsive P and S arrivals and higher-frequency content, and earthquake faulting parameters consistent with regional tectonic stresses. Its volcanic or fluid-influenced seismicity features were volcanic tremor, large CLVD components in moment tensor solutions, and increasing magnitudes with time. Earthquake location tests suggest that the earthquakes occurred in a distributed volume elongated in the NS direction either directly under the volcano or within 5-10 km south of it. Following the M<sub>W</sub> 5.8 event, earthquakes occurred in a new crustal volume slightly east and north of the previous earthquakes. The central Aleutian Arc is a tectonically active region with seismicity occurring in the crusts of the Pacific and North American plates in addition to interplate events. We postulate that the Kasatochi seismic swarm was a manifestation of the complex interaction of tectonic and magmatic processes in the Earth's crust. Although magmatic intrusion triggered the earthquakes in the swarm, the earthquakes failed in context of the regional stress field.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1029/2010JB007435","usgsCitation":"Ruppert, N.G., Prejean, S.G., and Hansen, R.A., 2011, Seismic swarm associated with the 2008 eruption of Kasatochi Volcano, Alaska: earthquake locations and source parameters: Journal of Geophysical Research, v. 116, no.

In particular, we delineate major crustal structures that may have played a role in the location of the earthquake and discuss the geometry of a nearby sedimentary basin that may have contributed to observed ground shaking. The February 21, 2008 M<sub>w</sub> 6.0 Wells earthquake, centered about 10 km northeast of Wells, Nevada, caused considerable damage to local buildings, especially in the historic old town area. The earthquake occurred on a previously unmapped normal fault and preliminary relocated events indicate a fault plane dipping about 55 degrees to the southeast. The epicenter lies near the intersection of major Basin and Range normal faults along the Ruby Mountains and Snake Mountains, and strike-slip faults in the southern Snake Mountains.\n\nRegionally, the Wells earthquake epicenter is aligned with a crustal-scale boundary along the edge of a basement gravity high that correlates to the Ruby Mountains fault zone. The Wells earthquake also occurred near a geophysically defined strike-slip fault that offsets buried plutonic rocks by about 30 km. In addition, a new depth-to-basement map, derived from the inversion of gravity data, indicates that the Wells earthquake and most of its associated aftershock sequence lie below a small oval- to rhomboid-shaped basin, that reaches a depth of about 2 km. Although the basin is of limited areal extent, it could have contributed to increased ground shaking in the vicinity of the city of Wells, Nevada, due to basin amplification of seismic waves.","language":"English","publisher":"Nevada Bureau of Mines and Geology","publisherLocation":"Reno, NV","usgsCitation":"Ponce, D.A., Watt, J.T., and Bouligand, C., 2011, Geophysical setting of the February 21, 2008 Mw 6 Wells earthquake, Nevada, and implications for earthquake hazards: Nevada Bureau of Mines and Geology Special Publication 36, 12 p.","productDescription":"12 p.","startPage":"89","endPage":"100","numberOfPages":"12","ipdsId":"IP-011599","costCenters":[{"id":309,"text":"Geology and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":275525,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":275524,"type":{"id":11,"text":"Document"},"url":"https://www.nbmg.unr.edu/pubs/sp/sp36/docs/III_d_(Ponce_&_Bouligand).pdf"}],"country":"United States","state":"Nevada","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -115.833333,40.0 ], [ -115.833333,41.666667 ], [ -114.0,41.666667 ], [ -114.0,40.0 ], [ -115.833333,40.0 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51f78ee7e4b02e26443a9382","contributors":{"authors":[{"text":"Ponce, David A. 0000-0003-4785-7354 ponce@usgs.gov","orcid":"https://orcid.org/0000-0003-4785-7354","contributorId":1049,"corporation":false,"usgs":true,"family":"Ponce","given":"David","email":"ponce@usgs.gov","middleInitial":"A.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true},{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":472930,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Watt, Janet T. 0000-0002-4759-3814","orcid":"https://orcid.org/0000-0002-4759-3814","contributorId":8564,"corporation":false,"usgs":true,"family":"Watt","given":"Janet","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":472931,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bouligand, C.","contributorId":55928,"corporation":false,"usgs":true,"family":"Bouligand","given":"C.","affiliations":[],"preferred":false,"id":472932,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

To assess how the migration strategies of bar-headed geese are influenced by environmental conditions, the relationship between migratory routes, temperatures, and vegetation coverage at stopovers sites estimated with the Normalized Difference Vegetation Index (NDVI) were analyzed. Our results showed that there were four typical migration routes in autumn with variation in timing among individuals in start and end times and in total migration and stopover duration. The observed variation may be related to habitat type and other environmental conditions along the routes. On average, these birds traveled about 1300 to 1500 km, refueled at three to six stopover sites and migrated for 73 to 83 days. The majority of the habitat types at stopover sites were lake, marsh, and shoal wetlands, with use of some mountainous regions, and farmland areas.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"International Journal of Zoology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Hindawi Publishing Corporation","doi":"10.1155/2011/323847","usgsCitation":"Zhang, Y., Hao, M., Takekawa, J.Y., Lei, F., Yan, B., Prosser, D.J., Douglas, D.C., Xing, Z., and Newman, S.H., 2011, Tracking the autumn migration of the bar-headed goose (<i>Anser indicus</i>) with satellite telemetry and relationship to environmental conditions: International Journal of Zoology, v. 2011, 323847; 10 p., https://doi.org/10.1155/2011/323847.","productDescription":"323847; 10 p.","numberOfPages":"10","ipdsId":"IP-030008","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":475045,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1155/2011/323847","text":"Publisher Index Page"},{"id":293847,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":293816,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1155/2011/323847"}],"country":"China","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 80.0,25.0 ], [ 80.0,35.0 ], [ 100.0,35.0 ], [ 100.0,25.0 ], [ 80.0,25.0 ] ] ] } } ] }","volume":"2011","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54140b2ce4b082fed288b9af","chorus":{"doi":"10.1155/2011/323847","url":"http://dx.doi.org/10.1155/2011/323847","publisher":"Hindawi Publishing Corporation","authors":"Zhang Yaonan, Hao Meiyu, Takekawa John Y., Lei Fumin, Yan Baoping, Prosser Diann J., Douglas David C., Xing Zhi, Newman Scott H.","journalName":"International Journal of Zoology","publicationDate":"2011","auditedOn":"9/25/2015","publiclyAccessibleDate":"1/1/2011"},"contributors":{"authors":[{"text":"Zhang, Yaonan","contributorId":50448,"corporation":false,"usgs":true,"family":"Zhang","given":"Yaonan","email":"","affiliations":[],"preferred":false,"id":501022,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hao, Meiyu","contributorId":32835,"corporation":false,"usgs":true,"family":"Hao","given":"Meiyu","email":"","affiliations":[],"preferred":false,"id":501020,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Takekawa, John Y. 0000-0003-0217-5907 john_takekawa@usgs.gov","orcid":"https://orcid.org/0000-0003-0217-5907","contributorId":176168,"corporation":false,"usgs":true,"family":"Takekawa","given":"John","email":"john_takekawa@usgs.gov","middleInitial":"Y.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":501017,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lei, Fumin","contributorId":33841,"corporation":false,"usgs":true,"family":"Lei","given":"Fumin","email":"","affiliations":[],"preferred":false,"id":501021,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Yan, Baoping","contributorId":76871,"corporation":false,"usgs":true,"family":"Yan","given":"Baoping","affiliations":[],"preferred":false,"id":501024,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Prosser, Diann J. 0000-0002-5251-1799 dprosser@usgs.gov","orcid":"https://orcid.org/0000-0002-5251-1799","contributorId":2389,"corporation":false,"usgs":true,"family":"Prosser","given":"Diann","email":"dprosser@usgs.gov","middleInitial":"J.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":501019,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Douglas, David C. 0000-0003-0186-1104 ddouglas@usgs.gov","orcid":"https://orcid.org/0000-0003-0186-1104","contributorId":2388,"corporation":false,"usgs":true,"family":"Douglas","given":"David","email":"ddouglas@usgs.gov","middleInitial":"C.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":501018,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Xing, Zhi","contributorId":61958,"corporation":false,"usgs":true,"family":"Xing","given":"Zhi","email":"","affiliations":[],"preferred":false,"id":501023,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Newman, Scott H.","contributorId":101372,"corporation":false,"usgs":true,"family":"Newman","given":"Scott","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":501025,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Of major concern among the land-use processes was the consumption of water through evaporation and transpiration by plants. The comparison of MF-FMP and IWFM was conducted and completed using a realistic hypothetical case study. Both models simulate the water demand for water-accounting units resulting from evapotranspiration and inefficiency losses and, for irrigated units, the supply from surface-water deliveries and groundwater pumpage. The MF-FMP simulates reductions in evapotranspiration owing to anoxia and wilting, and separately considers land-use-related evaporation and transpiration; IWFM simulates reductions in evapotranspiration related to the depletion of soil moisture. The models simulate inefficiency losses from precipitation and irrigation water applications to runoff and deep percolation differently. MF-FMP calculates the crop irrigation requirement and total farm delivery requirement, and then subtracts inefficiency losses from runoff and deep percolation. In IWFM, inefficiency losses to surface runoff from irrigation and precipitation are computed and subtracted from the total irrigation and precipitation before the crop irrigation requirement is estimated. Inefficiency losses in terms of deep percolation are computed simultaneously with the crop irrigation requirement. The seepage from streamflow routing also is computed differently and can affect certain hydrologic settings and magnitudes ofstreamflow infiltration. MF-FMP assumes steady-state conditions in the root zone; therefore, changes in soil moisture within the root zone are not calculated. IWFM simulates changes in the root zone in both irrigated and non-irrigated natural vegetation. Changes in soil moisture are more significant for non-irrigated natural vegetation areas than in the irrigated areas. Therefore, to facilitate the comparison of models, the changes in soil moisture are only simulated by IWFM for the natural vegetation areas, and soil-moisture parameters in irrigated regions in IWFM were specified at constant values . The IWFM total simulated changes in soil moisture that are related to natural vegetation areas vary from stress period to stress period but are small over the entire two-year period of simulation. In the hypothetical case study, IWFM simulates more evapotranspiration and return flows and less streamflow infiltration than MF-FMP. This causes more simulated surface-water diversions upstream and less simulated water available to downstream farms in IWFM compared to MF-FMP. The evapotranspiration simulated by the two models is well correlated even though the quantity is different. The different approaches used to simulate soil moisture, evapotranspiration, and inefficient losses yield different results for deep percolation and pumpage. In IWFM, deep percolation is a function of soil moisture; therefore, the constant soil-moisture requirement for irrigated regions, assumed for this comparison, results in a constant deep percolation rate. This led to poor correlation with the variable deep percolation rates simulated in MF-FMP, where the deep percolation rate, a fraction of inefficiency losses from precipitation and irrigation, is a function of quasi-steady state infiltration for each soil type and a function of groundwater head. Similarly, the larger simulated evapotranspiration in IWFM is mainly responsible for larger simulated groundwater pumpage demands and related lower groundwater levels in IWFM compared to MF-FMP. Because of the differences in features between MF-FMP and IWFM, the user may find that for certain hydrologic settings one model is better suited than the other. The performance of MF-FMP and IWFM in this particular hypothetical test case, with a fixed framework composed of common initial and boundary conditions and input parameter values, does not necessarily predict the performance of MF-FMP and IWFM in a real-world situation with variable framework and parameter values. These differences may affect the evaluation of policies, projects, or water-balance analysis for some hydrologic settings. Generally, both models are powerful tools that simulate a connected system of aquifer, stream networks, land surface, root zone, and runoff processes. MF-FMP simulated the hypothetical test case in about 4 minutes compared to about 58 minutes for IWFM.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Schmid, W., Dogural, E., Hanson, R.T., Kadir, T., and Chung, F., 2011, Comparison of simulations of land-use specific water demand and irrigation water supply by MF-FMP and IWFM: Technical Information Record TIR-2, xii, 68 p.","productDescription":"xii, 68 p.","numberOfPages":"80","ipdsId":"IP-001273","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":275589,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":275588,"type":{"id":11,"text":"Document"},"url":"https://baydeltaoffice.water.ca.gov/modeling/hydrology/IWFM/Publications/downloadables/Reports/IWFM%20and%20MF-FMP%20TIR-2%20(USGS-DWR%20Nov2011).pdf"}],"country":"United States","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51f8e061e4b0cecbe8fa9860","contributors":{"authors":[{"text":"Schmid, Wolfgang","contributorId":84020,"corporation":false,"usgs":false,"family":"Schmid","given":"Wolfgang","affiliations":[{"id":13040,"text":"Department of Hydrology and Water Resources, University of Arizona","active":true,"usgs":false}],"preferred":false,"id":476136,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dogural, Emin","contributorId":20629,"corporation":false,"usgs":true,"family":"Dogural","given":"Emin","email":"","affiliations":[],"preferred":false,"id":476133,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hanson, Randall T. 0000-0002-9819-7141 rthanson@usgs.gov","orcid":"https://orcid.org/0000-0002-9819-7141","contributorId":801,"corporation":false,"usgs":true,"family":"Hanson","given":"Randall","email":"rthanson@usgs.gov","middleInitial":"T.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":476132,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kadir, Tariq","contributorId":26208,"corporation":false,"usgs":true,"family":"Kadir","given":"Tariq","email":"","affiliations":[],"preferred":false,"id":476134,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Chung, Francis","contributorId":54488,"corporation":false,"usgs":true,"family":"Chung","given":"Francis","email":"","affiliations":[],"preferred":false,"id":476135,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

These older west-dipping faults are locally overprinted by a younger generation of east-dipping, high-angle normal faults that formed as early as the late Miocene and have remained active into the Quaternary. The most prominent of these east-dipping faults is the set of en-échelon, north-striking faults that bounds the east sides of the Ruby Mountains, East Humboldt Range, and Clover Hill (about 5 km southwest of Wells). The northeastern-most of these faults, the Clover Hill fault, projects northward along strike toward the Snake Mountains and the approximately located surface projection of the Wells earthquake fault as defined by aftershock locations. The Clover Hill fault also projects toward a previously unrecognized, east-facing Quaternary fault scarp and line of springs that appear to mark a significant east-dipping normal fault along the western edge of Town Creek Flat. Both western and eastern projections may be northern continuations of the Clover Hill fault. The Wells earthquake occurred along this east-dipping fault system.</p>\n<br>\n<p>Two possible alternatives to rupture of a northern continuation of the Clover Hill fault are that the earthquake fault (1) is antithetic to an active west-dipping fault or (2) reactivated a Mesozoic thrust fault that dips east as a result of tilting by the west-dipping faults along the west side of the Snake Mountains. Both alternatives are precluded by the depths of the earthquake and aftershocks, about 8 km and as deep as 12 km, respectively. These depths are below where an antithetic fault would intersect any main fault, and a tilted, formerly shallow and sub-horizontal thrust fault would not extend to depths of more than about 5–6 km.</p>\n<br>\n<p>The east-dipping, high-angle, earthquake fault cuts older west-dipping faults rather than reactivating them, highlighting a change in the structural style of Basin and Range extension in this region from closely-spaced, west-dipping faults that rotated significantly during slip and accommodated large-magnitude extension, to widely-spaced, high-angle faults that accommodate much less total strain over a long time span.</p>","language":"English","publisher":"Nevada Bureau of Mines and Geology","usgsCitation":"Henry, C.S., and Colgan, J.P., 2011, The regional structural setting of the 2008 Wells earthquake and Town Creek Flat Basin: implications for the Wells earthquake fault and adjacent structures: Nevada Bureau of Mines and Geology Special Publication 36, v.

Information concerning how reproductive ecology of endotherms might be influenced by growing season length (GSL) is rare, and species that breed over a broad geographic range provide an opportunity to study the effects of time constraints on reproductive strategies. We analyzed data from a temperate‐breeding bird, the lesser scaup&nbsp;</span><i>Aythya affinis</i><span>; hereafter scaup, collected at eight sites across a broad gradient of GSL to evaluate three hypotheses related to reproductive compensation in response to varying time constraints. Clutch initiation date in scaup was unaffected by GSL and was unrelated to latitude; spring thaw dates had a marginal impact on timing of breeding. Clutch size declined during the nesting season, as is reported frequently in bird species, but was also unaffected by GSL. Scaup do not appear to compensate for shorter growing seasons by more rapidly reducing clutch size. This study demonstrates that this species is remarkably consistent in terms of timing of breeding and clutch size, regardless of growing season characteristics. Such inflexibility could make this species particularly sensitive to environmental changes that affect resource availabilities.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1600-0587.2010.06622.x","usgsCitation":"Gurney, K.E., Clark, R., Slattery, S., Smith-Downey, N.V., Walker, J.I.,

This ecologically important landscape structure remained in a dynamic equilibrium for millennia prior to rapid degradation over the past century in response to human manipulation of the hydrologic system. Restoration of the patterned landscape structure is one of the primary objectives of the Everglades restoration effort. Recent research has revealed that three main drivers regulated feedbacks that initiated and maintained landscape structure: the spatial and temporal distribution of surface water depths, surface and subsurface flow, and phosphorus supply. Causes of recent degradation include but are not limited to perturbations to these historically important controls; shifts in mineral and sulfate supply may have also contributed to degradation. Restoring predrainage hydrologic conditions will likely preserve remaining landscape pattern structure, provided a sufficient supply of surface water with low nutrient and low total dissolved solids content exists to maintain a rainfall-driven water chemistry. However, because of hysteresis in landscape evolution trajectories, restoration of areas with a fully degraded landscape could require additional human intervention.</p>","language":"English","publisher":"CRC Press","publisherLocation":"Boca Raton, FL","doi":"10.1080/10643389.2010.531219","usgsCitation":"Larsen, L., Nicholas Aumen, Bernhardt, C.E., Engel, V., Givnish, T.J., S Hagerthey, P.M., Harvey, J., Leonard, L., McCormick, P., McVoy, C., Noe, G.E., Nungesser, M.K., Rutchey, K., Sklar, F., Troxler, T.G., Volin, J.C., and Willard, D.A., 2011, Recent and historic drivers of landscape change in the Everglades ridge, slough, and Tree Island mosaic: Critical Reviews in Environmental Science and Technology, v. 41, no. 1, p. 344-381, https://doi.org/10.1080/10643389.2010.531219.","productDescription":"33 p.","startPage":"344","endPage":"381","numberOfPages":"33","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-019250","costCenters":[{"id":436,"text":"National Research Program -

The inversion is tested with crosswell radar data collected in a laboratory tank. The model anomalies are consistent with the known heterogeneity in the tank; the model’s relative dielectric permittivity, which is calculated from the real part of the estimated complex slowness, is consistent with independent laboratory measurements.

Groundwater, pore water and surface wetland water data were used to help characterize the relationships between surface and groundwater with respect to nutrient dynamics. Photosynthesis and subsequent decomposition of vegetation in these hydrologically dynamic wetlands generates a large amount of dissolved C and N, although the subsurface till, derived in part from organic matter rich Pierre Shale, is a likely secondary source of nutrients in deeper groundwater. While surface water DOC concentrations ranged from 2.2 to 4.6 mM, groundwater values were 0.15 mM to 3.7 mM. Greater specific UV absorbance (SUVA<sub>254</sub>) in the wetland water column and in soil pore waters relative to groundwater indicate more reactive DOC in the surface to near-surface waters. Circumneutral wetlands had greater SUVA254, possibly because of variations in vegetation communities. The dominant inorganic nitrogen species was NH<sub>4</sub><sup>+</sup> in both wetland water and most ground water samples. The exceptions were 3 wells with NO<sub>3</sub><sup>-</sup> ranging from 38 to 115 μM. Shallow groundwater wells (Well 28 and Well 13S) with greater connection to wetland surface water had greater NH<sub>4</sub><sup>+</sup> concentrations (1.1 mM and 120 μM) than other well samples (3–90 μM). Pore water nutrient chemistry was more similar to surface water than ground water. Nitrogen results suggest reducing conditions in both groundwater and surface water, possibly due to the microbial uptake of O<sub>2</sub> by decaying vegetation in the wetland water column, labile organic C available in shallow groundwater, or the oxidation of pyrite associated with the subsurface.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Applied Geochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.apgeochem.2011.03.025","usgsCitation":"Holloway, J.M., Goldhaber, M.B., and Mills, C., 2011, Carbon and nitrogen biogeochemistry of a Prairie Pothole Wetland, Stutsman County, North Dakota, USA: Applied Geochemistry, v. 26, supplement, p.

River ecologists and fisheries managers are concerned about introduced flathead catfish populations because of the negative impacts on native fish communities or imperiled species associated with direct predation and indirect competition from this apex predator. We studied the trophic relations of introduced flathead catfish in an Atlantic river to further understand the effects on native fish communities. Crayfish (Astacidea) occurred most frequently in the flathead catfish diet, while sunfish <i>Lepomis</i> spp. comprised the greatest percentage by weight. Neither of two sympatric imperiled fish species (the federally endangered Cape Fear shiner <i>Notropis mekistocholas</i> and the Carolina redhorse <i>Moxostoma</i> sp., a federal species of concern) was found in any diet sample. An ontogenetic shift in diet was evident when flathead catfish reached about 300 mm, and length significantly explained the variation in the percent composition by weight of sunfish and darters <i>Etheostoma</i> and <i>Percina</i> spp. Flathead catfish showed positive prey selectivity for taxa that occupied similar benthic microhabitat, highlighting the importance of opportunistic feeding and prey encounter rates. Flathead catfish displayed a highly variable diel feeding chronology during July, when they had a mean stomach fullness of 0.32%, but then showed a single midday feeding peak during August (mean fullness = 0.52%). The gastric evacuation rate increased between July (0.40/h) and August (0.59/h), as did daily ration, which more than doubled between the 2 months (3.06% versus 7.37%). Our findings increase the understanding of introduced flathead catfish trophic relations and the degree of vulnerability among prey taxa, which resource managers may consider in fisheries management and conservation of native fish populations and imperiled species.</p>","language":"English","publisher":"American Fisheries Society","publisherLocation":"Bethesda, MD","doi":"10.1080/00028487.2011.607046","collaboration":"North Carolina Wildlife Resources Commission","usgsCitation":"Baumann, J.R., and Kwak, T.J., 2011, Trophic relations of introduced flathead catfish in an atlantic river: Transactions of the American Fisheries Society, v. 140, no. 4, p. 1120-1134, https://doi.org/10.1080/00028487.2011.607046.","productDescription":"15 p.","startPage":"1120","endPage":"1134","numberOfPages":"15","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-020792","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":305584,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"140","issue":"4","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationDate":"2011-08-22","publicationStatus":"PW","scienceBaseUri":"559ba6b5e4b0b94a640170d1","contributors":{"authors":[{"text":"Baumann, Jessica R.","contributorId":145490,"corporation":false,"usgs":false,"family":"Baumann","given":"Jessica","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":564197,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kwak, Thomas J. 0000-0002-0616-137X tkwak@usgs.gov","orcid":"https://orcid.org/0000-0002-0616-137X","contributorId":834,"corporation":false,"usgs":true,"family":"Kwak","given":"Thomas","email":"tkwak@usgs.gov","middleInitial":"J.","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":548957,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Fall migration spanned 11 weeks, including numerous stopovers en route, apparently for feeding. Spring migration from wintering sites to Middleton Island was shorter (4 weeks) and more direct. One juvenile spent several months in southern Prince William Sound. An adult spent several months near Craig, southeast Alaska, while three others overwintered in southern British Columbia. For all four wintering adults use of refuse-disposal sites was evident or strongly suggested. Commensalism with humans may have contributed to the increase on Middleton, but a strong case can also be made for a competing explanation-regional recruitment of gulls to high-quality nesting habitat in Alaska created after the earthquake of 1964. An analysis of band returns reveals broad overlap in the wintering grounds of gulls from different Alaska colonies and of gulls banded on the west coast from British Columbia to California. The seasonal movement of many gulls from Alaska is decidedly migratory, whereas gulls from British Columbia, Washington, and Oregon disperse locally in winter.</p>","language":"English","publisher":"Cooper Ornithological Club","publisherLocation":"Santa Clara, CA","doi":"10.1525/cond.2011.090224","usgsCitation":"Hatch, S.A., Gill, V., and Mulcahy, D.M., 2011, Migration And wintering areas Of Glaucous-winged Gulls From south-central Alaska: The Condor, v. 113, no. 2, p. 340-351, https://doi.org/10.1525/cond.2011.090224.","productDescription":"12 p.","startPage":"340","endPage":"351","numberOfPages":"12","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-017171","costCenters":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"links":[{"id":475046,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1525/cond.2011.090224","text":"Publisher Index Page"},{"id":298623,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -167.431640625,\n              56.84897198026975\n            ],\n            [\n              -167.431640625,\n              67.1016555307692\n            ],\n            [\n              -141.064453125,\n              67.1016555307692\n            ],\n            [\n              -141.064453125,\n              56.84897198026975\n            ],\n            [\n              -167.431640625,\n              56.84897198026975\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"113","issue":"2","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55095031e4b02e76d757e62a","contributors":{"authors":[{"text":"Hatch, Scott A. 0000-0002-0064-8187 shatch@usgs.gov","orcid":"https://orcid.org/0000-0002-0064-8187","contributorId":2625,"corporation":false,"usgs":true,"family":"Hatch","given":"Scott","email":"shatch@usgs.gov","middleInitial":"A.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":542475,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gill, V.A.","contributorId":35498,"corporation":false,"usgs":true,"family":"Gill","given":"V.A.","email":"","affiliations":[],"preferred":false,"id":542492,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mulcahy, Daniel M. dmulcahy@usgs.gov","contributorId":3102,"corporation":false,"usgs":true,"family":"Mulcahy","given":"Daniel","email":"dmulcahy@usgs.gov","middleInitial":"M.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":542493,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We compared samples collected in the late 1930s, the late 1960s, and the late 2000s using molecular genetic and stable isotope methods in an effort to determine whether White-tailed Ptarmigan on Mt. Evans, Colorado, have experiences recent environmental changes resulting in shifts in genetic diversity, gene frequency, and nutritional ecology.  We genotyped 115 individuals spanning the three time periods, using nine polymorphic microsatellite loci in our genetic analysis.  These samples were also analyzed for stable carbon and nitrogen isotopic composition.  We found a slight trend of lower heterozygosity through time, and allelic richness values were significantly lower in more recent times, but not significantly using an alpha of 0.05 (<i>P</i> < 0.1).  We found no changes in allele frequencies across time periods, suggesting that population sizes have not changed dramatically.  Feather δ<sup>13</sup>C and δ<sup>15</sup>N values decreased significantly across time periods, whereas the range in isotope values increased consistently from the late 1930s to the late time periods.  Inferred changes in the nutritional ecology of White-tailed Ptarmigan on Mt. Evans relate primarily to increased atmospheric deposition of nutrients that likely influenced foraging habits and tundra plant composition and nutritional quality.  Future work seeks to integrate genetic and isotopic data with long-term demographics to develop a detailed understanding of the interaction among environmental stressors on the long-term viability of ptarmigan populations.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Ecology, conservation, and management of grouse (Studies in Avian Biology no. 39)","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"University of California Press","publisherLocation":"Berkeley, CA","isbn":"9780520270060","usgsCitation":"Oyler-McCance, S.J., Stricker, C.A., St. John, J., Braun, C.E., Wann, G.T., and Aldridge, C.L., 2011, Effects of climate change on nutrition and genetics of White-tailed Ptarmigan, chap. <i>of</i> Ecology, conservation, and management of grouse (Studies in Avian Biology no. 39): Studies in Avian Biology, v. 39, p. 283-294.","productDescription":"12 p.","startPage":"283","endPage":"294","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":291420,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":352854,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://www.ucpress.edu/book.php?isbn=9780520270060"}],"volume":"39","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57fe7fd7e4b0824b2d147964","contributors":{"editors":[{"text":"Sandercock, Brett K.","contributorId":95816,"corporation":false,"usgs":true,"family":"Sandercock","given":"Brett","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":731909,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Martin, Kathy","contributorId":13478,"corporation":false,"usgs":true,"family":"Martin","given":"Kathy","affiliations":[],"preferred":false,"id":731910,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Segelbacher, Gernot","contributorId":90582,"corporation":false,"usgs":true,"family":"Segelbacher","given":"Gernot","affiliations":[],"preferred":false,"id":731911,"contributorType":{"id":2,"text":"Editors"},"rank":3}],"authors":[{"text":"Oyler-McCance, Sara J. 0000-0003-1599-8769 sara_oyler-mccance@usgs.gov","orcid":"https://orcid.org/0000-0003-1599-8769","contributorId":1973,"corporation":false,"usgs":true,"family":"Oyler-McCance","given":"Sara","email":"sara_oyler-mccance@usgs.gov","middleInitial":"J.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":497287,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stricker, Craig A. 0000-0002-5031-9437 cstricker@usgs.gov","orcid":"https://orcid.org/0000-0002-5031-9437","contributorId":1097,"corporation":false,"usgs":true,"family":"Stricker","given":"Craig","email":"cstricker@usgs.gov","middleInitial":"A.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":497286,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"St. John, Judy","contributorId":200881,"corporation":false,"usgs":false,"family":"St. John","given":"Judy","email":"","affiliations":[],"preferred":false,"id":497291,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Braun, Clait E.","contributorId":59368,"corporation":false,"usgs":true,"family":"Braun","given":"Clait","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":497290,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wann, Gregory T.","contributorId":48492,"corporation":false,"usgs":true,"family":"Wann","given":"Gregory","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":497288,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Aldridge, Cameron L. 0000-0003-3926-6941 aldridgec@usgs.gov","orcid":"https://orcid.org/0000-0003-3926-6941","contributorId":191773,"corporation":false,"usgs":true,"family":"Aldridge","given":"Cameron","email":"aldridgec@usgs.gov","middleInitial":"L.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":497289,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Alien forbs invade these grasslands, displacing both native and other alien species. Italian thistle is a noxious alien herb that has recently invaded these grasslands, including ungrazed blue oak (<i>Quercus douglassii</i>) and interior live oak (<i>Quercus wislizenii</i>) stands in Sequoia National Park. Here, Italian thistle tends to dominate under oaks and has the potential to substantially alter the foothill ecosystem by displacing native plants and acting as a ladder fuel that can carry fires into the oak canopy. We tested the effects of selectively reducing Italian thistle populations alone and in combination with restoration of native species. Two thistle eradication techniques (clipping and the application of clopyralid herbicide) and two restoration techniques (addition of native forb seeds or planting native grass plugs) were used. After two consecutive years of treatment we found: a) clipping was not effective at reducing Italian thistle populations (clipping reduced Italian thistle density in some areas, but not vegetative cover), b) herbicide reduced both Italian thistle density and vegetative cover for the first two growing seasons after application, but cover rebounded in the third growing season, c) native forb cover and species richness were not significantly affected by clipping or spot-treating with herbicide, d) the grass and forb addition treatments by themselves were not effective at reducing Italian thistle during the course of this study and e) sowing annual forb seeds after clipping resulted in greater forb cover and moderately reduced Italian thistle vegetative cover in the short term.","language":"English","publisher":"California Botanical Society","publisherLocation":"Berkeley, CA","doi":"10.3120/0024-9637-58.4.207","usgsCitation":"McGinnis, T., and Keeley, J., 2011, Effects of eradication and restoration treatments on Italian thistle (<i>Carduus pycnocephalus</i>): Madroño, v. 58, no. 4, p. 207-213, https://doi.org/10.3120/0024-9637-58.4.207.","productDescription":"7 p.","startPage":"207","endPage":"213","numberOfPages":"7","ipdsId":"IP-022976","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":475047,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://www.biodiversitylibrary.org/part/169151","text":"External Repository"},{"id":293746,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":293682,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3120/0024-9637-58.4.207"}],"country":"United States","state":"California","otherGeospatial":"Sequoia National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -118.919577,36.476008 ], [ -118.919577,36.596139 ], [ -118.749751,36.596139 ], [ -118.749751,36.476008 ], [ -118.919577,36.476008 ] ] ] } } ] }","volume":"58","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5412b9a7e4b0239f1986ba5a","contributors":{"authors":[{"text":"McGinnis, Thomas","contributorId":9976,"corporation":false,"usgs":true,"family":"McGinnis","given":"Thomas","affiliations":[],"preferred":false,"id":500684,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Keeley, Jon","contributorId":7782,"corporation":false,"usgs":true,"family":"Keeley","given":"Jon","affiliations":[],"preferred":false,"id":500683,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The proposed methodology is validated and applied in two different modeling scenarios: (a) Simulation and (b) lower trophic level ocean ecosystem model. The approach we develop relies on the ability to predict right singular vectors (resulting from a decomposition of computer model experimental output) based on the computer model input and an experimental set of parameters. Critically, we model the right singular vectors in terms of the model parameters via a nonlinear statistical model. Specifically, we focus our attention on first-order models of these right singular vectors rather than the second-order (covariance) structure.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Agricultural, Biological, and Environmental Statistics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s13253-011-0073-7","usgsCitation":"Hooten, M., Leeds, W.B., Fiechter, J., and Wikle, C.K., 2011, Assessing first-order emulator inference for physical parameters in nonlinear mechanistic models: Journal of Agricultural, Biological, and Environmental Statistics, v. 16, no. 4, p. 475-494, https://doi.org/10.1007/s13253-011-0073-7.","productDescription":"20 p.","startPage":"475","endPage":"494","costCenters":[{"id":189,"text":"Colorado Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":257229,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s13253-011-0073-7","linkFileType":{"id":5,"text":"html"}},{"id":257241,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"16","issue":"4","noUsgsAuthors":false,"publicationDate":"2011-11-03","publicationStatus":"PW","scienceBaseUri":"5059edd4e4b0c8380cd49a29","contributors":{"authors":[{"text":"Hooten, Mevin 0000-0002-1614-723X mhooten@usgs.gov","orcid":"https://orcid.org/0000-0002-1614-723X","contributorId":2958,"corporation":false,"usgs":true,"family":"Hooten","given":"Mevin","email":"mhooten@usgs.gov","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true},{"id":12963,"text":"Colorado Cooperative Fish and Wildlife Research Unit, Fort Collins, CO","active":true,"usgs":false}],"preferred":true,"id":350332,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Leeds, William B.","contributorId":45563,"corporation":false,"usgs":true,"family":"Leeds","given":"William","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":350334,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fiechter, Jerome","contributorId":8325,"corporation":false,"usgs":true,"family":"Fiechter","given":"Jerome","email":"","affiliations":[],"preferred":false,"id":350333,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Wikle, Christopher K.","contributorId":55680,"corporation":false,"usgs":true,"family":"Wikle","given":"Christopher","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":350335,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
