Climate change is altering long-term climatic conditions and increasing the magnitude of weather fluctuations. Assessing the consequences of these changes for terrestrial ecosystems requires understanding how different vegetation types respond to climate and weather. This study examined 20 years of regional-scale remotely sensed net primary productivity (NPP) in forests of the northern Lake States to identify how the relationship between NPP and climate or weather differ among forest types, and if NPP patterns are influenced by landscape-scale evenness of forest-type abundance. These results underscore the positive relationship between temperature and NPP. Importantly, these results indicate significant differences among broadly defined forest types in response to both climate and weather. Essentially all weather variables that were strongly related to annual NPP displayed significant differences among forest types, suggesting complementarity in response to environmental fluctuations. In addition, this study found that forest-type evenness (within 8 × 8 km2 areas) is positively related to long-term NPP mean and negatively related to NPP variability, suggesting that NPP in pixels with greater forest-type evenness is both higher and more stable through time. This is landscape- to subcontinental-scale evidence of a relationship between primary productivity and one measure of biological diversity. These results imply that anthropogenic or natural processes that influence the proportional abundance of forest types within landscapes may influence long-term productivity patterns.

Data record initial flooding of a latest Pleistocene river drainage and the formation of an estuary 9000. yr ago. Estuarine conditions were punctuated by two intervals of marine influence from approximately 4100 to 3700 and 1150 to 500. cal. yr BP. Foraminiferal assemblages in the muddy sand facies that accumulated during these intervals contain many well-preserved benthic foraminiferal species, which occur today in open marine settings as deep as the mid shelf, and significant numbers of well-preserved planktonic foraminifera, some typical of Gulf Stream waters. We postulate that these marine-influenced units resulted from temporary destruction of the southern Outer Banks barrier islands by hurricanes. The second increase in marine influence is coeval with increased rate of sea-level rise and a peak in Atlantic tropical cyclone activity during the Medieval Climate Anomaly. This high-resolution analysis demonstrates the range of environmental variability and the rapidity of coastal change that can result from the interplay of changing climate, sea level and geomorphology in an estuarine setting. ?? 2011 University of Washington.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.yqres.2011.06.012","issn":"00335894","usgsCitation":"Grand, P.C., Culver, S., Mallinson, D.J., Farrell, K., Corbett, D., Horton, B.P., Hillier, C., Riggs, S., Snyder, S., and Buzas, M., 2011, Rapid Holocene coastal change revealed by high-resolution micropaleontological analysis, Pamlico Sound, North Carolina, USA: Quaternary Research, v. 76, no. 3, p. 319-334, https://doi.org/10.1016/j.yqres.2011.06.012.","startPage":"319","endPage":"334","numberOfPages":"16","costCenters":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":241418,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213761,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.yqres.2011.06.012"}],"country":"United States","state":"North Carolina","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -76.4373779296875,\n 35.44053326772722\n ],\n [\n -76.4373779296875,\n 35.44277092585766\n ],\n [\n -76.43463134765625,\n 35.44277092585766\n ],\n [\n -76.43463134765625,\n 35.44053326772722\n ],\n [\n -76.4373779296875,\n 35.44053326772722\n ]\n ]\n ]\n }\n },\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -76.06109619140625,\n 34.75740963726007\n ],\n [\n -76.40304565429688,\n 34.755153088189324\n ],\n [\n -76.4044189453125,\n 35.430463036438276\n ],\n [\n -75.73699951171875,\n 35.430463036438276\n ],\n [\n -75.73837280273438,\n 34.75402479052889\n ],\n [\n -76.06109619140625,\n 34.75740963726007\n ]\n ]\n ]\n }\n }\n ]\n}","volume":"76","issue":"3","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"505a94b5e4b0c8380cd81582","contributors":{"authors":[{"text":"Grand, Pre C.","contributorId":6672,"corporation":false,"usgs":true,"family":"Grand","given":"Pre","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":437084,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Culver, S.J.","contributorId":53970,"corporation":false,"usgs":true,"family":"Culver","given":"S.J.","email":"","affiliations":[],"preferred":false,"id":437087,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mallinson, D.

The fault system that runs from southern California into Mexico is a simple strike-slip boundary: the west side of California and Mexico moves northwards with respect to the east. However, the Mw 7.2 2010 El Mayor–Cucapah earthquake on this fault system produced a pattern of seismic waves that indicates a far more complex source than slip on a planar strike-slip fault7. Here we use geodetic, remote-sensing and seismological data to reconstruct the fault geometry and history of slip during this earthquake. We find that the earthquake produced a straight 120-km-long fault trace that cut through the Cucapah mountain range and across the Colorado River delta. However, at depth, the fault is made up of two different segments connected by a small extensional fault. Both segments strike N130° E, but dip in opposite directions. The earthquake was initiated on the connecting extensional fault and 15 s later ruptured the two main segments with dominantly strike-slip motion. We show that complexities in the fault geometry at depth explain well the complex pattern of radiated seismic waves. We conclude that the location and detailed characteristics of the earthquake could not have been anticipated on the basis of observations of surface geology alone.

The poaching of tiger prey is a key threat to tiger persistence; a clear understanding of tiger diet is a prerequisite to conserve dwindling populations. We used unpublished data on tiger diet in combination with two previously published studies to examine fine-scale spatio-temporal changes in tiger diet relative to prey abundance in Chitwan National Park, Nepal, and aggregated data from the three studies to examine the effect that study duration and the size of the study area have on estimates of tiger diet. Our results correspond with those of previous studies: in all three studies, tiger diet was dominated by members of Cervidae; small to medium-sized prey was important in one study. Tiger diet was unrelated to prey abundance, and the aggregation of studies indicates that increasing study duration and study area size both result in increased dietary diversity in terms of prey categories consumed, and increasing study duration changed which prey species contributed most to tiger diet. Based on our results, we suggest that managers focus their efforts on minimizing the poaching of all tiger prey, and that future studies of tiger diet be of long duration and large spatial extent to improve our understanding of spatio-temporal variation in estimates of tiger diet.

A variety of techniques exist to obtain harvest data, such as hunter surveys, check stations, mandatory reporting requirements, and voluntary reporting of harvest. Agencies responsible for managing harvested wildlife such as deer (Odocoileus spp.), elk (Cervus elaphus), and pronghorn (Antilocapra americana) are challenged with balancing the cost of data collection versus the value of the information obtained. We compared precision, bias, and relative cost of several common strategies, including hunter self-reporting and random sampling, for estimating hunter harvest using a realistic set of simulations. Self-reporting with a follow-up survey of hunters who did not report produces the best estimate of harvest in terms of precision and bias, but it is also, by far, the most expensive technique. Self-reporting with no followup survey risks very large bias in harvest estimates, and the cost increases with increased response rate. Probability-based sampling provides a substantial cost savings, though accuracy can be affected by nonresponse bias. We recommend stratified random sampling with a calibration estimator used to reweight the sample based on the proportions of hunters responding in each covariate category as the best option for balancing cost and accuracy. ?? 2011 The Wildlife Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wildlife Society Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/wsb.61","issn":"00917648","usgsCitation":"Lukacs, P., Gude, J., Russell, R., and Ackerman, B., 2011, Evaluating cost-efficiency and accuracy of hunter harvest survey designs: Wildlife Society Bulletin, v. 35, no. 4, p. 430-437, https://doi.org/10.1002/wsb.61.","startPage":"430","endPage":"437","numberOfPages":"8","costCenters":[],"links":[{"id":499968,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doaj.org/article/b98da09300304c678a6901f9eacc8057","text":"External Repository"},{"id":213729,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/wsb.61"},{"id":241385,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"35","issue":"4","noUsgsAuthors":false,"publicationDate":"2011-09-21","publicationStatus":"PW","scienceBaseUri":"505a0bdde4b0c8380cd528ff","contributors":{"authors":[{"text":"Lukacs, P.M.","contributorId":84708,"corporation":false,"usgs":true,"family":"Lukacs","given":"P.M.","email":"","affiliations":[],"preferred":false,"id":437082,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gude, J.A.","contributorId":101092,"corporation":false,"usgs":true,"family":"Gude","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":437083,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Russell, R.E.","contributorId":34728,"corporation":false,"usgs":true,"family":"Russell","given":"R.E.","email":"","affiliations":[],"preferred":false,"id":437081,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ackerman, B.B.","contributorId":31698,"corporation":false,"usgs":true,"family":"Ackerman","given":"B.B.","email":"","affiliations":[],"preferred":false,"id":437080,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70032681,"text":"70032681 - 2011 - Hydrologic response of catchments to precipitation: Quantification of mechanical carriers and origins of water","interactions":[],"lastModifiedDate":"2012-03-12T17:21:23","indexId":"70032681","displayToPublicDate":"2011-01-01T00:00:00","publicationYear":"2011","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3722,"text":"Water Resources Research","onlineIssn":"1944-7973","printIssn":"0043-1397","active":true,"publicationSubtype":{"id":10}},"title":"Hydrologic response of catchments to precipitation: Quantification of mechanical carriers and origins of water","docAbstract":"Precipitation-induced overland and groundwater flow and mixing processes are quantified to analyze the temporal (event and pre-event water) and spatial (groundwater discharge and overland runoff) origins of water entering a stream. Using a distributed-parameter control volume finite-element simulator that can simultaneously solve the fully coupled partial differential equations describing 2-D Manning and 3-D Darcian flow and advective-dispersive transport, mechanical flow (driven by hydraulic potential) and tracer-based hydrograph separation (driven by dispersive mixing as well as mechanical flow) are simulated in response to precipitation events in two cross sections oriented parallel and perpendicular to a stream. The results indicate that as precipitation becomes more intense, the subsurface mechanical flow contributions tend to become less significant relative to the total pre-event stream discharge. Hydrodynamic mixing can play an important role in enhancing pre-event tracer signals in the stream. This implies that temporally tagged chemical signals introduced into surface-subsurface flow systems from precipitation may not be strong enough to detect the changes in the subsurface flow system. It is concluded that diffusive/dispersive mixing, capillary fringe groundwater ridging, and macropore flow can influence the temporal sources of water in the stream, but any sole mechanism may not fully explain the strong pre-event water discharge. Further investigations of the influence of heterogeneity, residence time, geomorphology, and root zone processes are required to confirm the conclusions of this study.

Few studies have documented relationships between landscape variables and deer migration strategies. From 2000 to 2007 we captured 267 adult female white-tailed deer (Odocoileus virginianus) at 7 study sites in Minnesota and South Dakota and monitored 149 individuals through ≥3 seasonal migration periods (585 deer-migration seasons). All deer classified as obligate migrators with ≥3 migrations (range 3–9 migration seasons) maintained their obligate status for the duration of the study. Multinomial logistic odds ratios from generalized estimating equations indicated that the odds of being a resident increased by 1.4 and 1.3 per 1-unit increase in forest patch density and mean area, respectively, compared to migrating deer. Odds of being an obligate migrator increased by 0.7 and 0.8 per 1-unit decrease in forest patch density and mean area, respectively, compared to resident or conditional migrating deer. Areas inhabited by resident deer were characterized by greater number of forest patches per 100 ha and larger mean forest patch area than conditional and obligate migrant areas. Odds of migrating increased by 1.1 per 1-unit increase in deer winter severity index. Migration behavior of white-tailed deer varied among regions, and land-cover and landscape characteristics provided predictive indicators of migration strategies for deer that could have important implications for conservation, metapopulation dynamics, and species management.

Increases in burned area and fire frequency are expected to stimulate boreal carbon losses. However, the impact of wildfires on carbon emissions is also affected by the severity of burning. How climate change influences the severity of biomass burning has proved difficult to assess. Here, we examined the depth of ground-layer combustion in 178 sites dominated by black spruce in Alaska, using data collected from 31 fire events between 1983 and 2005. We show that the depth of burning increased as the fire season progressed when the annual area burned was small. However, deep burning occurred throughout the fire season when the annual area burned was large. Depth of burning increased late in the fire season in upland forests, but not in peatland and permafrost sites. Simulations of wildfire-induced carbon losses from Alaskan black spruce stands over the past 60 years suggest that ground-layer combustion has accelerated regional carbon losses over the past decade, owing to increases in burn area and late-season burning. As a result, soils in these black spruce stands have become a net source of carbon to the atmosphere, with carbon emissions far exceeding decadal uptake.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Nature Geoscience","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Nature Publishing Group","publisherLocation":"London, U.K.","doi":"10.1038/ngeo1027","issn":"17520894","usgsCitation":"Turetsky, M., Kane, E., Harden, J., Ottmar, R., Manies, K., Hoy, E., and Kasischke, E., 2011, Recent acceleration of biomass burning and carbon losses in Alaskan forests and peatlands: Nature Geoscience, v. 4, no. 1, p. 27-31, https://doi.org/10.1038/ngeo1027.","productDescription":"5 p.","startPage":"27","endPage":"31","costCenters":[{"id":555,"text":"Soil Biogeochemistry Group","active":false,"usgs":true}],"links":[{"id":214472,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1038/ngeo1027"},{"id":242200,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-12-05","publicationStatus":"PW","scienceBaseUri":"505a95d6e4b0c8380cd81c70","contributors":{"authors":[{"text":"Turetsky, M.R.","contributorId":107470,"corporation":false,"usgs":true,"family":"Turetsky","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":442419,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kane, E.S.","contributorId":42275,"corporation":false,"usgs":true,"family":"Kane","given":"E.S.","email":"","affiliations":[],"preferred":false,"id":442416,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"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":442414,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ottmar, R.D.","contributorId":72603,"corporation":false,"usgs":true,"family":"Ottmar","given":"R.D.","email":"","affiliations":[],"preferred":false,"id":442418,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Manies, K.L.","contributorId":23228,"corporation":false,"usgs":true,"family":"Manies","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":442413,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Hoy, E.","contributorId":40439,"corporation":false,"usgs":true,"family":"Hoy","given":"E.","email":"","affiliations":[],"preferred":false,"id":442415,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Kasischke, E.S.","contributorId":61201,"corporation":false,"usgs":true,"family":"Kasischke","given":"E.S.","email":"","affiliations":[],"preferred":false,"id":442417,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}} ,{"id":70034409,"text":"70034409 - 2011 - The influence of irrigation water on the hydrology and lake water budgets of two small arid-climate lakes in Khorezm, Uzbekistan","interactions":[],"lastModifiedDate":"2013-04-25T12:16:48","indexId":"70034409","displayToPublicDate":"2011-01-01T00:00:00","publicationYear":"2011","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2342,"text":"Journal of Hydrology","active":true,"publicationSubtype":{"id":10}},"title":"The influence of irrigation water on the hydrology and lake water budgets of two small arid-climate lakes in Khorezm, Uzbekistan","docAbstract":"Little is known regarding the origins and hydrology of hundreds of small lakes located in the western Uzbekistan province of Khorezm, Central Asia. Situated in the Aral Sea Basin, Khorezm is a productive agricultural region, growing mainly cotton, wheat, and rice. Irrigation is provided by an extensive canal network that conveys water from the Amu Darya River (AD) throughout the province. The region receives on average 10 cm/year of precipitation, yet potential evapotranspiration exceeds this amount by about 15 times. It was hypothesized that the perennial existence of the lakes of interest depends on periodic input of excess irrigation water. This hypothesis was investigated by studying two small lakes in the region, Tuyrek and Khodjababa. In June and July 2008, surface water and shallow groundwater samples were collected at these lake systems and surrounding communities and analyzed for δ2H, δ18O, and major ion hydrochemistry to determine water sources. Water table and lake surface elevations were monitored, and the local aquifer characteristics were determined through aquifer tests. These data and climate data from a Class A evaporation pan and meteorological stations were used to estimate water budgets for both lakes. Lake evaporation was found to be about 0.7 cm/day during the study period. Results confirm that the waters sampled at both lake systems and throughout central Khorezm were evaporated from AD water to varying degrees. Together, the water budgets and stable isotope and major ion hydrochemistry data suggest that without surface water input from some source (i.e. excess irrigation water), these and other Khorezm lakes with similar hydrology may decrease in volume dramatically, potentially to the point of complete desiccation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.jhydrol.2011.09.028","issn":"00221694","usgsCitation":"Scott, J., Rosen, M.R., Saito, L., and Decker, D., 2011, The influence of irrigation water on the hydrology and lake water budgets of two small arid-climate lakes in Khorezm, Uzbekistan: Journal of Hydrology, v. 410, no. 1-2, p. 114-125, https://doi.org/10.1016/j.jhydrol.2011.09.028.","productDescription":"12 p.","startPage":"114","endPage":"125","numberOfPages":"12","costCenters":[{"id":465,"text":"Nevada Water Science Center","active":true,"usgs":true}],"links":[{"id":244531,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216648,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jhydrol.2011.09.028"}],"country":"Uzbekistan","state":"Khorezm","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 60.06,40.56 ], [ 60.06,42.00 ], [ 62.36,42.00 ], [ 62.36,40.56 ], [ 60.06,40.56 ] ] ] } } ] }","volume":"410","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bad2ae4b08c986b323a11","contributors":{"authors":[{"text":"Scott, J.","contributorId":57795,"corporation":false,"usgs":false,"family":"Scott","given":"J.","affiliations":[],"preferred":false,"id":445648,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rosen, Michael R.","contributorId":43096,"corporation":false,"usgs":true,"family":"Rosen","given":"Michael","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":445647,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Saito, L.","contributorId":59402,"corporation":false,"usgs":true,"family":"Saito","given":"L.","email":"","affiliations":[],"preferred":false,"id":445649,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Decker, D.L.","contributorId":71797,"corporation":false,"usgs":true,"family":"Decker","given":"D.L.","email":"","affiliations":[],"preferred":false,"id":445650,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70032678,"text":"70032678 - 2011 - A data-driven approach for modeling post-fire debris-flow volumes and their uncertainty","interactions":[],"lastModifiedDate":"2017-05-23T13:36:07","indexId":"70032678","displayToPublicDate":"2011-01-01T00:00:00","publicationYear":"2011","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1551,"text":"Environmental Modelling and Software","active":true,"publicationSubtype":{"id":10}},"title":"A data-driven approach for modeling post-fire debris-flow volumes and their uncertainty","docAbstract":"This study demonstrates the novel application of genetic programming to evolve nonlinear post-fire debris-flow volume equations from variables associated with a data-driven conceptual model of the western United States. The search space is constrained using a multi-component objective function that simultaneously minimizes root-mean squared and unit errors for the evolution of fittest equations. An optimization technique is then used to estimate the limits of nonlinear prediction uncertainty associated with the debris-flow equations. In contrast to a published multiple linear regression three-variable equation, linking basin area with slopes greater or equal to 30 percent, burn severity characterized as area burned moderate plus high, and total storm rainfall, the data-driven approach discovers many nonlinear and several dimensionally consistent equations that are unbiased and have less prediction uncertainty. Of the nonlinear equations, the best performance (lowest prediction uncertainty) is achieved when using three variables: average basin slope, total burned area, and total storm rainfall. Further reduction in uncertainty is possible for the nonlinear equations when dimensional consistency is not a priority and by subsequently applying a gradient solver to the fittest solutions. The data-driven modeling approach can be applied to nonlinear multivariate problems in all fields of study.

We used aerial photographs to compare early (1967/1971), middle (1982/1985), and late (2000/2003) periods and compared 1992 and 2001 National Land Cover Data (NLCD). Mean Cerulean Warbler detections per stop decreased at 68 BBS stops between the early (0.05) and middle (0.01) time periods and their distribution became more restricted (15 vs. 3% of stops), but the amount of deciduous/mixed forest increased. Mean detections at 240 stops decreased from the middle (0.09) to the late (0.06) time periods, but the deciduous/ mixed forest land cover and fragmentation metrics did not change. The amounts of deciduous/mixed forest, core forest area, and edge density in the NLCD analysis decreased from 1992 to 2001, whereas the amount of non-forest land cover increased. The number of Cerulean Warbler detections did not change (1992 = 0.08, 2001 = 0.10; P = 0.11). The lack of concordance between Cerulean Warbler detections and broad habitat features suggests that smaller, microhabitat features may be most important in affecting Cerulean Warbler breeding habitat suitability.

Landform surface properties influence the role these mountains have in geomorphic processes such as dust flux and surface hydrology across the region. The primary goal of this study was to describe and quantify land surface properties of arid-mountain landforms as a step toward unraveling the role these properties have in soil-geomorphic processes. As part of a larger soil-geomorphic study, four major landform types were identified within the southern Fry Mountains in the southwestern Mojave Desert on the basis of topography and landscape position: mountaintop, mountainflank, mountainflat (intra-range low-relief surface), and mountainbase. A suite of rock, vegetation, and morphometric land surface characteristic variables was measured at each of 65 locations across the study area, which included an associated piedmont and playa. Our findings show that despite the variation within types, landforms have distinct land surface properties that likely control soil-geomorphic processes. We hypothesize that surface expression influences a feedback process at this site where water transports sediment to low lying areas on the landscape and wind carries dust and soluble salts to the mountains where they are washed between rocks, incorporated into the soil, and retained as relatively long-term storage. Recent land-based video and satellite photographs of the dust cloud emanating from the Sierra Cucapá Mountains in response to the 7.2-magnitude earthquake near Mexicali, Mexico, support the hypothesis that these landforms are massive repositories of dust.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Catena","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.catena.2011.07.011","issn":"03418162","usgsCitation":"Hirmas, D., Graham, R., and Kendrick, K., 2011, Soil-geomorphic significance of land surface characteristics in an arid mountain range, Mojave Desert, USA: Catena, v. 87, no. 3, p. 408-420, https://doi.org/10.1016/j.catena.2011.07.011.","productDescription":"13 p.","startPage":"408","endPage":"420","costCenters":[{"id":234,"text":"Earthquake Hazards Program","active":true,"usgs":true},{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":241258,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213613,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.catena.2011.07.011"}],"country":"United States","otherGeospatial":"Mojave Desert","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.98,34.16 ], [ -117.98,37.52 ], [ -114.73,37.52 ], [ -114.73,34.16 ], [ -117.98,34.16 ] ] ] } } ] }","volume":"87","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9226e4b08c986b319d29","contributors":{"authors":[{"text":"Hirmas, D.R.","contributorId":107509,"corporation":false,"usgs":true,"family":"Hirmas","given":"D.R.","email":"","affiliations":[],"preferred":false,"id":437226,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Graham, R.C.","contributorId":33740,"corporation":false,"usgs":true,"family":"Graham","given":"R.C.","email":"","affiliations":[],"preferred":false,"id":437224,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kendrick, K.J. 0000-0002-9839-6861","orcid":"https://orcid.org/0000-0002-9839-6861","contributorId":48595,"corporation":false,"usgs":true,"family":"Kendrick","given":"K.J.","affiliations":[],"preferred":false,"id":437225,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70032381,"text":"70032381 - 2011 - Foaling rates in feral horses treated with the immunocontraceptive porcine zona pellucida","interactions":[],"lastModifiedDate":"2012-03-12T17:21:20","indexId":"70032381","displayToPublicDate":"2011-01-01T00:00:00","publicationYear":"2011","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3779,"text":"Wildlife Society Bulletin","onlineIssn":"1938-5463","printIssn":"0091-7648","active":true,"publicationSubtype":{"id":10}},"title":"Foaling rates in feral horses treated with the immunocontraceptive porcine zona pellucida","docAbstract":"Locally abundant feral horses (Equus caballus) can rapidly deplete available resources. Fertility control agents present promising nonlethal tools for reducing their population growth rates. We tested the effect of 2 forms of the immunocontraceptive porcine zona pellucida (PZP) on foaling rates in 3 populations of feral horses in the western United States. A liquid form requiring annual boosters was administered at Little Book Cliffs Wild Horse Range, Mesa County (CO), and Pryor Mountain Wild Horse Range, Bighorn County (WY) and Carbon County (MT), and a time-release pellet form designed to produce 2 yr of infertility was administered at McCullough Peaks Herd Management Area, Park County (WY). Average foaling rates (foals born/mare-yr) from direct observation of untreated and treated female horses (mares), 2004-2008, were 60.1% (n = 153 mare-yr) versus 6.6% (n = 91 mare-yr) at Little Book Cliffs, and 62.8% (n = 129 mare-yr) versus 17.7% (n = 79 mare-yr) at Pryor Mountain, respectively. At McCullough Peaks, mean annual foaling rates from 2006 to 2008 were 75.0% (n = 48 mare-yr) for untreated mares and 31.7% (n = 101 mare-yr) for treated mares. Controlling for age of mares and pretreatment differences in fertility, PZP reduced foaling rates in all 3 herds. The pellets used at McCullough Peaks (produced by cold evaporation) were less effective than pellets used in a previous trial and produced by heat extrusion. Immunocontraception with PZP may be a useful tool in reducing fertility rates in some western United States feral horse herds, but population growth reduction will depend on timely access to mares for inoculation and the proportion of mares that can be successfully treated. ?? 2011 The Wildlife Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wildlife Society Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/wsb.66","issn":"00917648","usgsCitation":"Ransom, J., Roelle, J.E., Cade, B., Coates-Markle, L., and Kane, A., 2011, Foaling rates in feral horses treated with the immunocontraceptive porcine zona pellucida: Wildlife Society Bulletin, v. 35, no. 4, p. 343-352, https://doi.org/10.1002/wsb.66.","startPage":"343","endPage":"352","numberOfPages":"10","costCenters":[],"links":[{"id":475171,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doaj.org/article/eaf8cdf3e2884576b2ca16c93d535b6b","text":"Publisher Index Page"},{"id":213686,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/wsb.66"},{"id":241337,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"35","issue":"4","noUsgsAuthors":false,"publicationDate":"2011-10-17","publicationStatus":"PW","scienceBaseUri":"505a12abe4b0c8380cd543cb","contributors":{"authors":[{"text":"Ransom, J.I.","contributorId":68970,"corporation":false,"usgs":true,"family":"Ransom","given":"J.I.","email":"","affiliations":[],"preferred":false,"id":435883,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Roelle, J.

In this approach, the U.S. Geological Survey lunar calibration system was utilized to provide high-precision lunar exoatmospheric spectral irradiance predictions for a ground-based sensor location, and when combined with ground measurement viewing geometry, provided the column optical transmittance for retrievals of AOD. Automated multiwavelength lunar measurements were obtained using an unmodified Cimel-318 sunphotometer sensor to assess existing capabilities and enhancements needed for day/night operation in NASA's Aerosol Robotic Network (AERONET). Results show that even existing photometers can provide the ability for retrievals of aerosol optical depths at night near full moon. With an additional photodetector signal-to-noise improvement of 10-100, routine use over the bright half of the lunar phase and a much wider range of wavelengths and conditions can be achieved. Although the lunar cycle is expected to limit the frequency of observations to 30%-40% compared to solar measurements, nevertheless this is an attractive extension of AERONET capabilities. ?? 2011 American Meteorological Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Atmospheric and Oceanic Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1175/JTECH-D-10-05036.1","issn":"07390572","usgsCitation":"Berkoff, T., Sorokin, M., Stone, T., Eck, T., Hoff, R., Welton, E., and Holben, B., 2011, Nocturnal aerosol optical depth measurements with a small-aperture automated photometer using the moon as a light source: Journal of Atmospheric and Oceanic Technology, v. 28, no. 10, p. 1297-1306, https://doi.org/10.1175/JTECH-D-10-05036.1.","startPage":"1297","endPage":"1306","numberOfPages":"10","costCenters":[],"links":[{"id":475248,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"http://hdl.handle.net/11603/33424","text":"Publisher Index Page"},{"id":213716,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1175/JTECH-D-10-05036.1"},{"id":241371,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"10","noUsgsAuthors":false,"publicationDate":"2011-10-01","publicationStatus":"PW","scienceBaseUri":"505a6728e4b0c8380cd731e9","contributors":{"authors":[{"text":"Berkoff, T.A.","contributorId":74965,"corporation":false,"usgs":true,"family":"Berkoff","given":"T.A.","email":"","affiliations":[],"preferred":false,"id":435897,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sorokin, M.","contributorId":23343,"corporation":false,"usgs":true,"family":"Sorokin","given":"M.","email":"","affiliations":[],"preferred":false,"id":435893,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stone, T.","contributorId":18900,"corporation":false,"usgs":true,"family":"Stone","given":"T.","email":"","affiliations":[],"preferred":false,"id":435892,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Eck, T.F.","contributorId":46778,"corporation":false,"usgs":true,"family":"Eck","given":"T.F.","email":"","affiliations":[],"preferred":false,"id":435894,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hoff, R.","contributorId":74208,"corporation":false,"usgs":true,"family":"Hoff","given":"R.","email":"","affiliations":[],"preferred":false,"id":435896,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Welton, E.","contributorId":58474,"corporation":false,"usgs":true,"family":"Welton","given":"E.","email":"","affiliations":[],"preferred":false,"id":435895,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Holben, B.","contributorId":75762,"corporation":false,"usgs":true,"family":"Holben","given":"B.","affiliations":[],"preferred":false,"id":435898,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}} ,{"id":70032388,"text":"70032388 - 2011 - Migration delays caused by anthropogenic barriers: Modeling dams, temperature, and success of migrating salmon smolts","interactions":[],"lastModifiedDate":"2012-03-12T17:21:20","indexId":"70032388","displayToPublicDate":"2011-01-01T00:00:00","publicationYear":"2011","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1450,"text":"Ecological Applications","active":true,"publicationSubtype":{"id":10}},"title":"Migration delays caused by anthropogenic barriers: Modeling dams, temperature, and success of migrating salmon smolts","docAbstract":"Disruption to migration is a growing problem for conservation and restoration of animal populations. Anthropogenic barriers along migration paths can delay or prolong migrations, which may result in a mismatch with migration-timing adaptations. To understand the interaction of dams (as barriers along a migration path), seasonally changing environmental conditions, timing of Atlantic salmon (Salmo salar) downstream migration, and ultimate migration success, we used 10 years of river temperature and discharge data as a template upon which we simulated downstream movement of salmon. Atlantic salmon is a cool-water species whose downstream migrating smolts must complete migration before river temperatures become too warm. We found that dams had a local effect on survival as well as a survival effect that was spatially and temporally removed from the encounter with the dam. While smolts are delayed by dams, temperatures downstream can reach lethal or near-lethal temperatures;as a result, the match between completion of migration and the window of appropriate migration conditions can be disrupted. The strength of this spatially and temporally removed effect is at least comparable to the local effects of dams in determining smolt migration success in the presence of dams. We also considered smolts from different tributaries, varying in distance from the river mouth, to assess the potential importance of locally adapted migration timing on the effect of barriers. Migration-initiation temperature affected modeled smolt survival differentially across tributaries, with the success of smolts from upstream tributaries being much more variable across years than that of smolts with a shorter distance to travel. As a whole, these results point to the importance of broadening our spatial and temporal view when managing migrating populations. We must consider not only how many individuals never make it across migration barriers, but also the spatially and temporally removed consequences of delays at the barriers for those individuals that successfully navigate them. ??2011 by the Ecological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/10-0593.1","issn":"10510761","usgsCitation":"Marschall, E., Mather, M.E., Parrish, D., Allison, G., and McMenemy, J., 2011, Migration delays caused by anthropogenic barriers: Modeling dams, temperature, and success of migrating salmon smolts: Ecological Applications, v. 21, no. 8, p. 3014-3031, https://doi.org/10.1890/10-0593.1.","startPage":"3014","endPage":"3031","numberOfPages":"18","costCenters":[],"links":[{"id":213813,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/10-0593.1"},{"id":241472,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a56ffe4b0c8380cd6d99f","contributors":{"authors":[{"text":"Marschall, E.A.","contributorId":55124,"corporation":false,"usgs":true,"family":"Marschall","given":"E.A.","email":"","affiliations":[],"preferred":false,"id":435915,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mather, M.

This investigation evaluated the performance of GPR on two different granitic regoliths of somewhat different mineralogical composition in the San Jacinto Mountains of southern California. Radar records collected at a site where soils are Alfisols were more depth restricted than the radar record obtained at a site where soils are Entisols. Although the Alfisols contain an argillic horizon, and the Entisols have no such horizon of clay accumulation, the main impact on GPR effectiveness is related to mineralogy. The bedrock at the Alfisol site, which contains more mafic minerals (5% hornblende and 20% biotite), is more attenuating to GPR than the bedrock at the Entisol site, where mafic mineral content is less (<1% hornblende and 10% biotite). Thus, a relatively minor variation in bedrock mineralogy, specifically the increased biotite content, severely restricts the performance of GPR.

This area included drainages of the Lower Mississippi, Arkansas‐White‐Red, and Texas‐Gulf hydrologic regions. The models were standardized to reflect nutrient sources and stream conditions during 2002. Model predictions of nutrient loads (mass per time) and yields (mass per area per time) generally were greatest in streams in the eastern part of the region and along reaches near the Texas and Louisiana shoreline. The Mississippi River and Atchafalaya River watersheds, which drain nearly two‐thirds of the conterminous U.S., delivered the largest nutrient loads to the Gulf of Mexico, as expected. However, the three largest delivered TN yields were from the Trinity River/Galveston Bay, Calcasieu River, and Aransas River watersheds, while the three largest delivered TP yields were from the Calcasieu River, Mermentau River, and Trinity River/Galveston Bay watersheds. Model output indicated that the three largest sources of nitrogen from the region were atmospheric deposition (42%), commercial fertilizer (20%), and livestock manure (unconfined, 17%). The three largest sources of phosphorus were commercial fertilizer (28%), urban runoff (23%), and livestock manure (confined and unconfined, 23%).

The central color swath of the HiRISE instrument has three separate charge‐coupled devices (CCDs) and color filters that observe the surface in rapid cadence. Active features, such as dust devils, appear in motion when observed by this region of the instrument. Our image animations reveal clear circulatory motion within dust devils that is separate from their translational motion across the Martian surface. Both manual and automated tracking of dust devil clouds reveal tangential winds that approach 20–30 m s−1 in some cases. These winds are sufficient to induce a ∼1% decrease in atmospheric pressure within the dust devil core relative to ambient, facilitating dust lifting by reducing the threshold wind speed for particle elevation. Finally, radial velocity profiles constructed from our automated measurements test the Rankine vortex model for dust devil structure. Our profiles successfully reveal the solid body rotation component in the interior, but fail to conclusively illuminate the profile in the outer regions of the vortex. One profile provides evidence for a velocity decrease as a function of r−1/2, instead of r−1, suggestive of surface friction effects. However, other profiles do not support this observation, or do not contain enough measurements to produce meaningful insights.

Even though disease has profound effects on condition, few studies have experimentally tested its effects on trait expression and even fewer have identified a mechanistic basis for these effects. Recent evidence suggests that black and white, but not grey, plumage colors of black-capped chickadees (Poecile atricapillus) are sexually selected. We therefore hypothesized that birds afflicted with avian keratin disorder, a condition that affects the beak and other keratinized tissues, would show reduced expression of black and white, but not grey, color. UV-vis spectrometry of black-capped chickadees affected and unaffected by avian keratin disorder revealed spectral differences between them consistent with this hypothesis. To elucidate the mechanistic bases of these differences, we used scanning electron microscopy (SEM), electron-dispersive x-ray spectroscopy (EDX) and a feather cleaning experiment. SEM showed extreme feather soiling in affected birds, and EDX revealed that this was most likely from external sources. Experimentally cleaning the feathers increased color expression of ornamental feathers of affected, but not unaffected, birds. These data provide strong evidence that black and white color is an honest indicator in chickadees, and that variation in feather dirtiness, likely due to differences in preening behavior is a mechanism for this association.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"PLoS ONE","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1371/journal.pone.0025877","issn":"19326203","usgsCitation":"D'Alba, L., Van Hemert, C.R., Handel, C.M., and Shawkey, M., 2011, A natural experiment on the condition-dependence of achromatic plumage reflectance in black-capped chickadees: PLoS ONE, v. 6, no. 10, https://doi.org/10.1371/journal.pone.0025877.","costCenters":[],"links":[{"id":475404,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0025877","text":"Publisher Index Page"},{"id":243513,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215692,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1371/journal.pone.0025877"}],"volume":"6","issue":"10","noUsgsAuthors":false,"publicationDate":"2011-10-03","publicationStatus":"PW","scienceBaseUri":"5059e494e4b0c8380cd4673b","contributors":{"authors":[{"text":"D'Alba, L.","contributorId":9079,"corporation":false,"usgs":true,"family":"D'Alba","given":"L.","affiliations":[],"preferred":false,"id":446769,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Van Hemert, Caroline R. 0000-0002-6858-7165 cvanhemert@usgs.gov","orcid":"https://orcid.org/0000-0002-6858-7165","contributorId":3592,"corporation":false,"usgs":true,"family":"Van Hemert","given":"Caroline","email":"cvanhemert@usgs.gov","middleInitial":"R.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":446772,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Handel, Colleen M. 0000-0002-0267-7408 cmhandel@usgs.gov","orcid":"https://orcid.org/0000-0002-0267-7408","contributorId":3067,"corporation":false,"usgs":true,"family":"Handel","given":"Colleen","email":"cmhandel@usgs.gov","middleInitial":"M.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":446770,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Shawkey, M.D.","contributorId":97731,"corporation":false,"usgs":true,"family":"Shawkey","given":"M.D.","email":"","affiliations":[],"preferred":false,"id":446771,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70033782,"text":"70033782 - 2011 - Mercury capture by selected Bulgarian fly ashes: Influence of coal rank and fly ash carbon pore structure on capture efficiency","interactions":[],"lastModifiedDate":"2012-03-12T17:21:30","indexId":"70033782","displayToPublicDate":"2011-01-01T00:00:00","publicationYear":"2011","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":835,"text":"Applied Geochemistry","active":true,"publicationSubtype":{"id":10}},"title":"Mercury capture by selected Bulgarian fly ashes: Influence of coal rank and fly ash carbon pore structure on capture efficiency","docAbstract":"Mercury capture by fly ash C was investigated at five lignite- and subbituminous-coal-burning Bulgarian power plants (Republika, Bobov Dol, Maritza East 2, Maritza East 3, and Sliven). Although the C content of the ashes is low, never exceeding 1.6%, the Hg capture on a unit C basis demonstrates that the low-rank-coal-derived fly ash carbons are more efficient in capturing Hg than fly ash carbons from bituminous-fired power plants. While some low-C and low-Hg fly ashes do not reveal any trends of Hg versus C, the 2nd and, in particular, the 3rd electrostatic precipitator (ESP) rows at the Republika power plant do have sufficient fly ash C range and experience flue gas sufficiently cool to capture measurable amounts of Hg. The Republika 3rd ESP row exhibits an increase in Hg with increasing C, as observed in other power plants, for example, in Kentucky power plants burning Appalachian-sourced bituminous coals. Mercury/C decreases with an increase in fly ash C, suggesting that some of the C is isolated from the flue gas stream and does not contribute to Hg capture. Mercury capture increases with an increase in Brunauer-Emmett-Teller (BET) surface area and micropore surface area. The differences in Hg capture between the Bulgarian plants burning low-rank coal and high volatile bituminous-fed Kentucky power plants suggests that the variations in C forms resulting from the combustion of the different ranks also influence the efficiency of Hg capture. ?? 2010 Elsevier Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Applied Geochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.apgeochem.2010.10.009","issn":"08832927","usgsCitation":"Kostova, I., Hower, J., Mastalerz, M., and Vassilev, S., 2011, Mercury capture by selected Bulgarian fly ashes: Influence of coal rank and fly ash carbon pore structure on capture efficiency: Applied Geochemistry, v. 26, no. 1, p. 18-27, https://doi.org/10.1016/j.apgeochem.2010.10.009.","startPage":"18","endPage":"27","numberOfPages":"10","costCenters":[],"links":[{"id":214473,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.apgeochem.2010.10.009"},{"id":242201,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a53eae4b0c8380cd6cdeb","contributors":{"authors":[{"text":"Kostova, I.J.","contributorId":7096,"corporation":false,"usgs":true,"family":"Kostova","given":"I.J.","email":"","affiliations":[],"preferred":false,"id":442420,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hower, J.C.","contributorId":100541,"corporation":false,"usgs":true,"family":"Hower","given":"J.C.","email":"","affiliations":[],"preferred":false,"id":442423,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mastalerz, Maria","contributorId":78065,"corporation":false,"usgs":true,"family":"Mastalerz","given":"Maria","affiliations":[],"preferred":false,"id":442422,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Vassilev, S.V.","contributorId":48777,"corporation":false,"usgs":true,"family":"Vassilev","given":"S.V.","email":"","affiliations":[],"preferred":false,"id":442421,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70033785,"text":"70033785 - 2011 - Comparison of Two Parametric Methods to Estimate Pesticide Mass Loads in California's Central Valley","interactions":[],"lastModifiedDate":"2018-02-15T13:34:13","indexId":"70033785","displayToPublicDate":"2011-01-01T00:00:00","publicationYear":"2011","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2529,"text":"Journal of the American Water Resources Association","active":true,"publicationSubtype":{"id":10}},"title":"Comparison of Two Parametric Methods to Estimate Pesticide Mass Loads in California's Central Valley","docAbstract":"Mass loadings were calculated for four pesticides in two watersheds with different land uses in the Central Valley, California, by using two parametric models: (1) the Seasonal Wave model (SeaWave), in which a pulse signal is used to describe the annual cycle of pesticide occurrence in a stream, and (2) the Sine Wave model, in which first-order Fourier series sine and cosine terms are used to simulate seasonal mass loading patterns. The models were applied to data collected during water years 1997 through 2005. The pesticides modeled were carbaryl, diazinon, metolachlor, and molinate. Results from the two models show that the ability to capture seasonal variations in pesticide concentrations was affected by pesticide use patterns and the methods by which pesticides are transported to streams. Estimated seasonal loads compared well with results from previous studies for both models. Loads estimated by the two models did not differ significantly from each other, with the exceptions of carbaryl and molinate during the precipitation season, where loads were affected by application patterns and rainfall. However, in watersheds with variable and intermittent pesticide applications, the SeaWave model is more suitable for use on the basis of its robust capability of describing seasonal variation of pesticide concentrations. ?? 2010 American Water Resources Association.

TGL concentration of fish exposed to 180mgL-1 clove oil was significantly higher than those of the rest anaesthetic groups. AST activities of fish exposed to 120, 150 and 180mgL-1 were significantly higher than those of 60 and 90mgL-1. Overall, TGL and AST could be potentially used as indicators of anaesthetic stress for juvenile Siberian sturgeon. Based on blood biochemical parameters, the appropriate anaesthetic concentrations of MS-222 and clove oil were 80-120mgL-1 and 60-90mgL-1, respectively. Clove oil was a promising alternative to MS-222. ?? 2011 Blackwell Verlag, Berlin.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Applied Ichthyology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1439-0426.2011.01711.x","issn":"01758659","usgsCitation":"Feng, G., Zhuang, P., Zhang, L., Kynard, B., Shi, X., Duan, M., Liu, J., and Huang, X., 2011, Effect of anaesthetics MS-222 and clove oil on blood biochemical parameters of juvenile Siberian sturgeon (Acipenser baerii): Journal of Applied Ichthyology, v. 27, no. 2, p. 595-599, https://doi.org/10.1111/j.1439-0426.2011.01711.x.","startPage":"595","endPage":"599","numberOfPages":"5","costCenters":[],"links":[{"id":214530,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1439-0426.2011.01711.x"},{"id":242264,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"27","issue":"2","noUsgsAuthors":false,"publicationDate":"2011-03-28","publicationStatus":"PW","scienceBaseUri":"505a05bee4b0c8380cd50f27","contributors":{"authors":[{"text":"Feng, G.","contributorId":9456,"corporation":false,"usgs":true,"family":"Feng","given":"G.","email":"","affiliations":[],"preferred":false,"id":442463,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zhuang, P.","contributorId":49892,"corporation":false,"usgs":true,"family":"Zhuang","given":"P.","email":"","affiliations":[],"preferred":false,"id":442468,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Zhang, L.","contributorId":41543,"corporation":false,"usgs":true,"family":"Zhang","given":"L.","email":"","affiliations":[],"preferred":false,"id":442466,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kynard, B.","contributorId":51232,"corporation":false,"usgs":true,"family":"Kynard","given":"B.","email":"","affiliations":[],"preferred":false,"id":442469,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Shi, X.","contributorId":82142,"corporation":false,"usgs":true,"family":"Shi","given":"X.","email":"","affiliations":[],"preferred":false,"id":442470,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Duan, M.","contributorId":28440,"corporation":false,"usgs":true,"family":"Duan","given":"M.","email":"","affiliations":[],"preferred":false,"id":442465,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Liu, J.","contributorId":23672,"corporation":false,"usgs":false,"family":"Liu","given":"J.","affiliations":[],"preferred":false,"id":442464,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Huang, X.","contributorId":43161,"corporation":false,"usgs":true,"family":"Huang","given":"X.","email":"","affiliations":[],"preferred":false,"id":442467,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}} ,{"id":70033787,"text":"70033787 - 2011 - Lithosphere-asthenosphere interaction beneath the western United States from the joint inversion of body-wave traveltimes and surface-wave phase velocities","interactions":[],"lastModifiedDate":"2012-03-12T17:21:25","indexId":"70033787","displayToPublicDate":"2011-01-01T00:00:00","publicationYear":"2011","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1803,"text":"Geophysical Journal International","active":true,"publicationSubtype":{"id":10}},"title":"Lithosphere-asthenosphere interaction beneath the western United States from the joint inversion of body-wave traveltimes and surface-wave phase velocities","docAbstract":"The relation between the complex geological history of the western margin of the North American plate and the processes in the mantle is still not fully documented and understood. Several pre-USArray local seismic studies showed how the characteristics of key geological features such as the Colorado Plateau and the Yellowstone Snake River Plains are linked to their deep mantle structure. Recent body-wave models based on the deployment of the high density, large aperture USArray have provided far more details on the mantle structure while surface-wave tomography (ballistic waves and noise correlations) informs us on the shallow structure. Here we combine constraints from these two data sets to image and study the link between the geology of the western United States, the shallow structure of the Earth and the convective processes in mantle. Our multiphase DNA10-S model provides new constraints on the extent of the Archean lithosphere imaged as a large, deeply rooted fast body that encompasses the stable Great Plains and a large portion of the Northern and Central Rocky Mountains. Widespread slow anomalies are found in the lower crust and upper mantle, suggesting that low-density rocks isostatically sustain part of the high topography of the western United States. The Yellowstone anomaly is imaged as a large slow body rising from the lower mantle, intruding the overlying lithosphere and controlling locally the seismicity and the topography. The large E-W extent of the USArray used in this study allows imaging the 'slab graveyard', a sequence of Farallon fragments aligned with the currently subducting Juan de Fuca Slab, north of the Mendocino Triple Junction. The lithospheric root of the Colorado Plateau has apparently been weakened and partly removed through dripping. The distribution of the slower regions around the Colorado Plateau and other rigid blocks follows closely the trend of Cenozoic volcanic fields and ancient lithospheric sutures, suggesting that the later exert a control on the locus of magmato-tectonic activity today.

The surveys extended from water depths of 4 m to 22 m and covered an area of 3.14 km2, 45.8% of which was bedrock, gravel, and coarse-grained sand and 54.2% was fine-grained sand. Our analyses of the bathymetric and acoustic backscatter data demonstrates that during the 6 months between surveys, 11.4% of the study area was buried by fine-grained sand while erosion resulted in the exposure of bedrock or coarse-grained sand over 26.5% of the study area. The probability of burial decreased with increasing water depth and rugosity; the probability of exhumation increased with increasing wave-induced near-bed shear stress, seabed slope and rugosity. Much of the detected change was at the boundary between bedrock and unconsolidated sediment due to sedimentation and erosion burying or exhuming bedrock, respectively. In a number of cases, however, the change in seabed character was apparently due to changes in sediment grain size when scour exposed what appeared to be an underlying coarser-grained lag or the burial of coarser-grained sand and gravel by fine-grained sand. These findings suggest that, in some places, (a) burial and exhumation of nearshore bedrock reefs along rocky, energetic inner shelves occurs over seasonal timescales and appears related to intrinsic factors such as seabed morphology and extrinsic factors such as wave forces, and (b) single acoustic surveys typically employed for geologic characterization and/or habitat mapping may not adequately characterize the geomorphologic and sedimentologic nature of these types of environments that typify most of the Pacific Ocean and up to 50% of the world's coastlines.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.margeo.2011.09.010","issn":"00253227","usgsCitation":"Storlazzi, C., Fregoso, T., Golden, N., and Finlayson, D., 2011, Sediment dynamics and the burial and exhumation of bedrock reefs along an emergent coastline as elucidated by repetitive sonar surveys: Northern Monterey Bay, CA: Marine Geology, v. 289, no. 1-4, p. 46-59, https://doi.org/10.1016/j.margeo.2011.09.010.","productDescription":"14 p.","startPage":"46","endPage":"59","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":215660,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.margeo.2011.09.010"},{"id":243479,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"state":"California","otherGeospatial":"Monterey Bay","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.145,36.629 ], [ -122.145,36.941 ], [ -121.828,36.941 ], [ -121.828,36.629 ], [ -122.145,36.629 ] ] ] } } ] }","volume":"289","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8988e4b08c986b316e10","contributors":{"authors":[{"text":"Storlazzi, C.

This procedure can be used to derive rotational ground motions and strains using arrayed translational data, thus providing an efficient way to calibrate the performance of rotational sensors. This approach does not require a priori information about the noise level of the translational data and elastic properties of the media. This new procedure also provides estimates of the standard deviations of the derived rotations and strains. In this study, we validated this code using synthetic translational waveforms from a seismic array. The results after the inversion of the synthetics for rotations were almost identical with the results derived using a well-tested inversion procedure by Spudich and Fletcher (2009). This new 2D procedure can be applied three times to obtain the full, three-component rotations. Additional modifications can be implemented to the code in the future to study different features of the rotational ground motions and strains induced by the passage of seismic waves.","language":"English","publisher":"Seismological Society of America","doi":"10.1785/0120100204","issn":"00371106","usgsCitation":"Chi, W., Lee, W., Aston, J., Lin, C., and Liu, C., 2011, Inversion of ground-motion data from a seismometer array for rotation using a modification of Jaeger's method: Bulletin of the Seismological Society of America, v. 101, no. 6, p. 3105-3109, https://doi.org/10.1785/0120100204.","productDescription":"5 p.","startPage":"3105","endPage":"3109","numberOfPages":"5","ipdsId":"IP-022928","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":213877,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120100204"},{"id":241543,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"101","issue":"6","noUsgsAuthors":false,"publicationDate":"2011-12-08","publicationStatus":"PW","scienceBaseUri":"505a3e53e4b0c8380cd63ca6","contributors":{"authors":[{"text":"Chi, Wu-Cheng","contributorId":26148,"corporation":false,"usgs":true,"family":"Chi","given":"Wu-Cheng","email":"","affiliations":[],"preferred":false,"id":435933,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lee, W.H.K.","contributorId":35303,"corporation":false,"usgs":true,"family":"Lee","given":"W.H.K.","affiliations":[],"preferred":false,"id":435934,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Aston, J.A.D.","contributorId":55650,"corporation":false,"usgs":true,"family":"Aston","given":"J.A.D.","email":"","affiliations":[],"preferred":false,"id":435935,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lin, C.J.","contributorId":99385,"corporation":false,"usgs":true,"family":"Lin","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":435937,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Liu, C.-C.","contributorId":89662,"corporation":false,"usgs":true,"family":"Liu","given":"C.-C.","affiliations":[],"preferred":false,"id":435936,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}} ]}
