We found that pre-1950 Minnesota wolf skulls were similar in size to those of wolves from southeastern Ontario and smaller than those of western wolves. However, Minnesota wolf skulls during 1970-1976 showed a shift to the larger, western form. Although Minnesota skull measurements after 1976 were unavailable, rostral ratios from 1969 through 1999 were consistent with hybridization between the smaller eastern wolf and the western form. Our findings help resolve the different taxonomic interpretations of Minnesota skull morphology and are consistent with molecular evidence of recent hybridization or intergradation of the two forms of wolves in Minnesota. Together these data indicate that eastern- and western-type wolves historically mixed and hybridized in Minnesota and continue to do so. Our findings are relevant to a recent government proposal to delist wolves from the endangered species list in Minnesota and surrounding states.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Zoology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/Z11-097","issn":"00084301","usgsCitation":"Mech, L., Nowak, R.M., and Weisberg, S., 2011, Use of cranial characters in taxonomy of the Minnesota wolf (Canis sp.): Canadian Journal of Zoology, v. 89, no. 12, p. 1188-1194, https://doi.org/10.1139/Z11-097.","startPage":"1188","endPage":"1194","numberOfPages":"7","costCenters":[],"links":[{"id":215073,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/Z11-097"},{"id":242843,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"89","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bbedee4b08c986b329820","contributors":{"authors":[{"text":"Mech, L.D. 0000-0003-3944-7769","orcid":"https://orcid.org/0000-0003-3944-7769","contributorId":75466,"corporation":false,"usgs":false,"family":"Mech","given":"L.D.","email":"","affiliations":[],"preferred":false,"id":435517,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nowak, R.

As a consequence of logistical constraints, investigators typically rely on sign surveys. Most survey methods, however, do not explicitly address the central problem of imperfect detections of animal signs in the field, leading to underestimates of true habitat occupancy and distribution.</p>\n<br/>\n<p>2. We assessed habitat occupancy for a tiger <i>Panthera tigris</i> metapopulation across a c. 38 000-km<sup>2</sup> landscape in India, employing a spatially replicated survey to explicitly address imperfect detections. Ecological predictions about tiger presence were confronted with sign detection data generated from occupancy sampling of 205 sites, each of 188 km<sup>2</sup>.</p>\n<br/>\n<p>3. A recent occupancy model that considers Markovian dependency among sign detections on spatial replicates performed better than the standard occupancy model (ΔAIC = 184·9). A formulation of this model that fitted the data best showed that density of ungulate prey and levels of human disturbance were key determinants of local tiger presence. Model averaging resulted in a replicate-level detection probability [inline image] = 0·17 (0·17) for signs and a tiger habitat occupancy estimate of [inline image] = 0·665 (0·0857) or 14 076 (1814) km2 of potential habitat of 21 167 km<sup>2</sup>. In contrast, a traditional presence-versus-absence approach underestimated occupancy by 47%. Maps of probabilities of local site occupancy clearly identified tiger source populations at higher densities and matched observed tiger density variations, suggesting their potential utility for population assessments at landscape scales.</p>\n<br/>\n<p>4. Synthesis and applications. Landscape-scale sign surveys can efficiently assess large carnivore spatial distributions and elucidate the factors governing their local presence, provided ecological and observation processes are both explicitly modelled. Occupancy sampling using spatial replicates can be used to reliably and efficiently identify tiger population sources and help monitor metapopulations. Our results reinforce earlier findings that prey depletion and human disturbance are key drivers of local tiger extinctions and tigers can persist even in human-dominated landscapes through effective protection of source populations. Our approach facilitates efficient targeting of tiger conservation interventions and, more generally, provides a basis for the reliable integration of large carnivore monitoring data between local and landscape scales.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Applied Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Blackwell Scientific Publications","publisherLocation":"Oxford, United Kingdom","doi":"10.1111/j.1365-2664.2011.02002.x","issn":"00218901","usgsCitation":"Karanth, K.U., Gopalaswamy, A., Kumar, N.S., Vaidyanathan, S., Nichols, J., and MacKenzie, D.I., 2011, Monitoring carnivore populations at the landscape scale: occupancy modelling of tigers from sign surveys: Journal of Applied Ecology, v. 48, no. 4, p. 1048-1056, https://doi.org/10.1111/j.1365-2664.2011.02002.x.","productDescription":"9 p.","startPage":"1048","endPage":"1056","numberOfPages":"9","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":475282,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1365-2664.2011.02002.x","text":"Publisher Index Page"},{"id":245807,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217835,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2664.2011.02002.x"}],"country":"India","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 72.01,10.83 ], [ 72.01,19.94 ], [ 79.91,19.94 ], [ 79.91,10.83 ], [ 72.01,10.83 ] ] ] } } ] }","volume":"48","issue":"4","noUsgsAuthors":false,"publicationDate":"2011-05-11","publicationStatus":"PW","scienceBaseUri":"505a5d93e4b0c8380cd70481","contributors":{"authors":[{"text":"Karanth, Kota Ullas","contributorId":42815,"corporation":false,"usgs":true,"family":"Karanth","given":"Kota","email":"","middleInitial":"Ullas","affiliations":[],"preferred":false,"id":458667,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gopalaswamy, Arjun M.","contributorId":12167,"corporation":false,"usgs":true,"family":"Gopalaswamy","given":"Arjun M.","affiliations":[],"preferred":false,"id":458665,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kumar, Narayanarao Samba","contributorId":102307,"corporation":false,"usgs":true,"family":"Kumar","given":"Narayanarao","email":"","middleInitial":"Samba","affiliations":[],"preferred":false,"id":458669,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Vaidyanathan, Srinivas","contributorId":15444,"corporation":false,"usgs":true,"family":"Vaidyanathan","given":"Srinivas","email":"","affiliations":[],"preferred":false,"id":458666,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Nichols, James D. 0000-0002-7631-2890 jnichols@usgs.gov","orcid":"https://orcid.org/0000-0002-7631-2890","contributorId":405,"corporation":false,"usgs":true,"family":"Nichols","given":"James D.","email":"jnichols@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":458664,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"MacKenzie, Darryl I.","contributorId":94436,"corporation":false,"usgs":true,"family":"MacKenzie","given":"Darryl","email":"","middleInitial":"I.","affiliations":[],"preferred":false,"id":458668,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Disparities within data sets employed to design and parameterize boundary value problems used in heuristic simulation inevitably introduce various levels of bias. The objective was to evaluate the impact of boundary value problem complexity on process representation for different runoff generation mechanisms. The comprehensive physics-based hydrologic response model InHM has been employed to generate base case simulations for four well-characterized catchments. The C3 and CB catchments are located within steep, forested environments dominated by subsurface stormflow; the TW and R5 catchments are located in gently sloping rangeland environments dominated by Dunne and Horton overland flows. Observational details are well captured within all four of the base case simulations, but the characterization of soil depth, permeability, rainfall intensity, and evapotranspiration differs for each. These differences are investigated through the conversion of each base case into a reduced case scenario, all sharing the same level of complexity. Evaluation of how individual boundary value problem characteristics impact simulated runoff generation processes is facilitated by quantitative analysis of integrated and distributed responses at high spatial and temporal resolution. Generally, the base case reduction causes moderate changes in discharge and runoff patterns, with the dominant process remaining unchanged. Moderate differences between the base and reduced cases highlight the importance of detailed field observations for parameterizing and evaluating physics-based models. Overall, similarities between the base and reduced cases indicate that the simpler boundary value problems may be useful for concept development simulation to investigate fundamental controls on the spectrum of runoff generation mechanisms.

Numerous studies have indicated that BR varies in space. However, many empirical ER models still use a global constant BR largely due to the lack of a functional description for BR. In this study, we redefined BR to be ecosystem respiration rate at the mean annual temperature. To test the validity of this concept, we conducted a synthesis analysis using 276 site-years of eddy covariance data, from 79 research sites located at latitudes ranging from ∼3°S to ∼70°N. Results showed that mean annual ER rate closely matches ER rate at mean annual temperature. Incorporation of site-specific BR into global ER model substantially improved simulated ER compared to an invariant BR at all sites. These results confirm that ER at the mean annual temperature can be considered as BR in empirical models. A strong correlation was found between the mean annual ER and mean annual gross primary production (GPP). Consequently, GPP, which is typically more accurately modeled, can be used to estimate BR. A light use efficiency GPP model (i.e., EC-LUE) was applied to estimate global GPP, BR and ER with input data from MERRA (Modern Era Retrospective-Analysis for Research and Applications) and MODIS (Moderate resolution Imaging Spectroradiometer).

Thus, lake depth relative to maximum ice thickness (1·5–2·0 m) represents an important threshold that impacts permafrost, aquatic habitat, and potentially geomorphic and hydrologic behaviour. We studied coupled hydrogeomorphic processes of 13 lakes representing a depth gradient across this threshold of maximum ice thickness by analysing remotely sensed, water quality, and climatic data over a 35-year period. Shoreline erosion rates due to permafrost degradation ranged from < 0·2 m/year in very shallow lakes (0·4 m) up to 1·8 m/year in the deepest lakes (2·6 m). This pattern of thermokarst expansion masked detection of lake hydrologic change using remotely sensed imagery except for the shallowest lakes with stable shorelines. Changes in the surface area of these shallow lakes tracked interannual variation in precipitation minus evaporation (P − E<sub>L</sub>) with periods of full and nearly dry basins. Shorter-term (2004–2008) specific conductance data indicated a drying pattern across lakes of all depths consistent with the long-term record for only shallow lakes. Our analysis suggests that grounded-ice lakes are ice-free on average 37 days longer than floating-ice lakes resulting in a longer period of evaporative loss and more frequent negative P − E<sub>L</sub>. These results suggest divergent hydrogeomorphic responses to a changing Arctic climate depending on the threshold created by water depth relative to maximum ice thickness in ACP lakes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrological Processes","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1002/hyp.8019","issn":"08856087","usgsCitation":"Arp, C., Jones, B.M., Urban, F., and Grosse, G., 2011, Hydrogeomorphic processes of thermokarst lakes with grounded-ice and floating-ice regimes on the Arctic coastal plain, Alaska: Hydrological Processes, v. 25, no. 15, p. 2422-2438, https://doi.org/10.1002/hyp.8019.","productDescription":"17 p.","startPage":"2422","endPage":"2438","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":246471,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218460,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/hyp.8019"}],"country":"United States","state":"Alaska","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 172.5,51.2 ], [ 172.5,71.4 ], [ -130.0,71.4 ], [ -130.0,51.2 ], [ 172.5,51.2 ] ] ] } } ] }","volume":"25","issue":"15","noUsgsAuthors":false,"publicationDate":"2011-03-04","publicationStatus":"PW","scienceBaseUri":"505a34f5e4b0c8380cd5fb72","contributors":{"authors":[{"text":"Arp, C.D.","contributorId":54715,"corporation":false,"usgs":true,"family":"Arp","given":"C.D.","email":"","affiliations":[],"preferred":false,"id":455166,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jones, Benjamin M. 0000-0002-1517-4711 bjones@usgs.gov","orcid":"https://orcid.org/0000-0002-1517-4711","contributorId":2286,"corporation":false,"usgs":true,"family":"Jones","given":"Benjamin","email":"bjones@usgs.gov","middleInitial":"M.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":118,"text":"Alaska Science Center Geography","active":true,"usgs":true}],"preferred":true,"id":455165,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Urban, F.E. 0000-0002-1329-1703","orcid":"https://orcid.org/0000-0002-1329-1703","contributorId":34352,"corporation":false,"usgs":true,"family":"Urban","given":"F.E.","affiliations":[],"preferred":false,"id":455164,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Grosse, G.","contributorId":82140,"corporation":false,"usgs":true,"family":"Grosse","given":"G.","affiliations":[],"preferred":false,"id":455167,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

One uses aftershocks as empirical Green&rsquo;s functions to determine a finite-fault slip distribution. The second uses mainshock ground-motion spectra to calculate source, path, and site response parameters. The slip inversion reveals a prominent asperity at the hypocenter with an area of approximately 6 km<sup>2</sup>, moment of 7.0 x 10<sup>23</sup> dyn cm&nbsp;(<i>M<sub>w</sub></i> 5.20), and stress drop of about 100 bars. Considering all major and minor slip, the total moment is 1.7 x 10<sup>24</sup> dyn cm&nbsp;(<i>M<sub>w</sub></i>=5.45). The rupture velocity is not resolvable due to the small source area. After fixing the geometric spreading, the source, path, and site parameter inversion yields a similar moment of 8.8 x 10<sup>23</sup> dyn cm&nbsp;(<i>M<sub>w</sub></i> 5.26) and a corner frequency of 0.89 Hz, which also give a stress drop of approximately 100 bars.

The resistivity model presented shows conductive structures in the western section of the study area terminating abruptly at the Arava Fault. For a more detailed analysis we performed a joint interpretation of the resistivity model with a P wave velocity model from a partially coincident seismic experiment. The technique used is a statistical correlation of resistivity and velocity values in parameter space. Regions of high probability of a coexisting pair of values for the two parameters are mapped back into the spatial domain, illustrating the geographical location of lithological classes. In this study, four regions of enhanced probability have been identified, and are remapped as four lithological classes. This technique confirms the Arava Fault marks the boundary of a highly conductive lithological class down to a depth of ∼3 km. That the fault acts as an impermeable barrier to fluid flow is unusual for large fault zone, which often exhibit a fault zone characterized by high conductivity and low seismic velocity. At greater depths it is possible to resolve the Precambrian basement into two classes characterized by vastly different resistivity values but similar seismic velocities. The boundary between these classes is approximately coincident with the Al Quweira Fault, with higher resistivities observed east of the fault. This is interpreted as evidence for the original deformation along the DST originally taking place at the Al Quweira Fault, before being shifted to the Arava Fault.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2011GC003678","issn":"15252027","usgsCitation":"Stankiewicz, J., Munoz, G., Ritter, O., Bedrosian, P.A., Ryberg, T., Weckmann, U., and Weber, M., 2011, Shallow lithological structure across the Dead Sea Transform derived from geophysical experiments: Geochemistry, Geophysics, Geosystems, v. 12, no. 7, Q07019, 15 p., https://doi.org/10.1029/2011GC003678.","productDescription":"Q07019, 15 p.","ipdsId":"IP-027651","costCenters":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":475115,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2011gc003678","text":"Publisher Index Page"},{"id":246337,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218337,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2011GC003678"}],"country":"Jordan, Israel","otherGeospatial":"Dead Sea","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              35,\n              29.5\n            ],\n            [\n              36,\n              29.5\n            ],\n            [\n              36,\n              31\n            ],\n            [\n              35,\n              31\n            ],\n            [\n              35,\n              29.5\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"12","issue":"7","noUsgsAuthors":false,"publicationDate":"2011-07-23","publicationStatus":"PW","scienceBaseUri":"505b8e31e4b08c986b3187ac","contributors":{"authors":[{"text":"Stankiewicz, J.","contributorId":42823,"corporation":false,"usgs":true,"family":"Stankiewicz","given":"J.","email":"","affiliations":[],"preferred":false,"id":455128,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Munoz, G.","contributorId":20197,"corporation":false,"usgs":true,"family":"Munoz","given":"G.","email":"","affiliations":[],"preferred":false,"id":455126,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ritter, O.","contributorId":33515,"corporation":false,"usgs":true,"family":"Ritter","given":"O.","email":"","affiliations":[],"preferred":false,"id":455127,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bedrosian, Paul A. 0000-0002-6786-1038 pbedrosian@usgs.gov","orcid":"https://orcid.org/0000-0002-6786-1038","contributorId":839,"corporation":false,"usgs":true,"family":"Bedrosian","given":"Paul","email":"pbedrosian@usgs.gov","middleInitial":"A.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true},{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":455131,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ryberg, T.","contributorId":91643,"corporation":false,"usgs":true,"family":"Ryberg","given":"T.","email":"","affiliations":[],"preferred":false,"id":455129,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Weckmann, U.","contributorId":14186,"corporation":false,"usgs":true,"family":"Weckmann","given":"U.","email":"","affiliations":[],"preferred":false,"id":455125,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Weber, M.","contributorId":93231,"corporation":false,"usgs":true,"family":"Weber","given":"M.","email":"","affiliations":[],"preferred":false,"id":455130,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Conversely, the dominantly bimodal nature of many putative arc-related igneous suites throughout southern Laurentia, including the Green Mountain arc, has also been used to support models of growth by extension of pre-existing crust. We report new geochemical and isotopic data from ∼1780-Ma gabbroic and granodioritic to tonalitic rocks of the Big Creek Gneiss, interpreted as consanguineous with previously studied metavolcanic rocks of the Green Mountain Formation.</p><p id=\"spar0010\">The ∼1780-Ma Big Creek Gneiss mafic rocks show clear geochemical signatures of a subduction origin and provide no supporting evidence for extensional tectonism. The ∼1780-Ma Big Creek Gneiss felsic rocks are attributed to partial melting of mafic and/or mixed lower-crustal material. The bimodal nature of the suite results from the combination of arc basalts and felsic crustal melts.

The samples were collected between 67°N and 78°N, in water depths of 155 to 2375&nbsp;m and were retrieved on cruises between A.D. 1964 and 2009. Grain size, magnetic characteristics, and colour reflectance data were also obtained on many of the samples. Twenty-one non-clay and 10 clay mineral species were identified; the average wt.% of the non-clay minerals was 70% and was dominated by quartz, various feldspars, and dolomite, whereas the dominant clay minerals were 1 M illite, biotite, and chlorite. Cluster analysis on principal component scores identified three main mineral groups, which also had strong associations with grain size and sediment magnetic properties. Box cores from the deep central basin (&gt;2000&nbsp;m) all show an abrupt drop in calcite wt.% (post-5 cal ka BP?) following a major peak in detrital carbonate (mainly dolomite). This dolomite-rich detrital carbonate (DC) event in JR175BC06 is possibly coeval with the Younger Dryas cold event. Four possible glacial-sourced end members were employed in a compositional unmixing algorithm to gain insight into down core changes in sediment provenance at the deep central basin. Estimates of the rates of sediment accumulation in the central basin are only in the range of 2 to 4&nbsp;cm/cal ka, surprisingly low given the glaciated nature of the surrounding land.</span></p>","language":"English","publisher":"Canadian Science Publishing","doi":"10.1139/e11-021","issn":"00084077","usgsCitation":"Andrews, J.T., and Eberl, D.D., 2011, Surface (sea floor) and near-surface (box cores) sediment mineralogy in Baffin Bay as a key to sediment provenance and ice sheet variations: Canadian Journal of Earth Sciences, v. 48, no. 9, p. 1307-1328, https://doi.org/10.1139/e11-021.","productDescription":"22 p.","startPage":"1307","endPage":"1328","costCenters":[],"links":[{"id":243402,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215588,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/e11-021"}],"otherGeospatial":"Baffin Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -86.1328125,\n              76.05850791800292\n            ],\n            [\n              -63.54492187500001,\n              65.54936668811527\n            ],\n            [\n              -46.58203125,\n              66.96447630005638\n            ],\n            [\n              -49.833984375,\n              73.52839948765174\n            ],\n            [\n              -67.060546875,\n              78.56048828398782\n            ],\n            [\n              -77.51953125,\n              79.07181201408547\n            ],\n            [\n              -86.1328125,\n              77.2544787022853\n            ],\n            [\n              -86.1328125,\n              76.05850791800292\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"48","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9f85e4b08c986b31e646","contributors":{"authors":[{"text":"Andrews, John T.","contributorId":79678,"corporation":false,"usgs":true,"family":"Andrews","given":"John","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":446071,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Eberl, D.

Sampling of wild birds for avian influenza virus (AIV) is often conducted in remote regions, but results are often delayed because of the need to transport samples to a laboratory equipped for molecular testing. Real-time reverse transcriptase polymerase chain reaction (rRT-PCR) is a molecular technique that offers one of the most accurate and sensitive methods for diagnosis of AIV. The previously strict lab protocols needed for rRT-PCR are now being adapted for the field. Development of freeze-dried (lyophilized) reagents that do not require cold chain, with sensitivity at the level of wet reagents has brought on-site remote testing to a practical goal. Here we present a method for the rapid diagnosis of AIV in wild birds using an rRT-PCR unit (Ruggedized Advanced Pathogen Identification Device or RAPID, Idaho Technologies, Salt Lake City, UT) that employs lyophilized reagents (Influenza A Target 1 Taqman; ASAY-ASY-0109, Idaho Technologies). The reagents contain all of the necessary components for testing at appropriate concentrations in a single tube: primers, probes, enzymes, buffers and internal positive controls, eliminating errors associated with improper storage or handling of wet reagents. The portable unit performs a screen for Influenza A by targeting the matrix gene and yields results in 2-3 hours. Genetic subtyping is also possible with H5 and H7 primer sets that target the hemagglutinin gene. The system is suitable for use on cloacal and oropharyngeal samples collected from wild birds, as demonstrated here on the migratory shorebird species, the western sandpiper (Calidrus mauri) captured in Northern California. Animal handling followed protocols approved by the Animal Care and Use Committee of the U.S. Geological Survey Western Ecological Research Center and permits of the U.S. Geological Survey Bird Banding Laboratory. The primary advantage of this technique is to expedite diagnosis of wild birds, increasing the chances of containing an outbreak in a remote location. On-site diagnosis would also prove useful for identifying and studying infected individuals in wild populations. The opportunity to collect information on host biology (immunological and physiological response to infection) and spatial ecology (migratory performance of infected birds) will provide insights into the extent to which wild birds can act as vectors for AIV over long distances.","language":"English","publisher":"JoVE","doi":"10.3791/2829","issn":"1940087X","usgsCitation":"Takekawa, J.Y., Hill, N., Schultz, A., Iverson, S.A., Cardona, C., Boyce, W., and Dudley, J., 2011, Rapid diagnosis of avian influenza virus in wild birds: Use of a portable rRT-PCR and freeze-dried reagents in the field: Journal of Visualized Experiments, v. 54, e2829, https://doi.org/10.3791/2829.","productDescription":"e2829","costCenters":[],"links":[{"id":475410,"rank":3,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/3217620","text":"External Repository"},{"id":217479,"rank":2,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3791/2829"},{"id":245430,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"54","noUsgsAuthors":false,"publicationDate":"2011-08-02","publicationStatus":"PW","scienceBaseUri":"505a94d3e4b0c8380cd8163d","contributors":{"authors":[{"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":457546,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hill, N.J.","contributorId":55655,"corporation":false,"usgs":true,"family":"Hill","given":"N.J.","email":"","affiliations":[],"preferred":false,"id":457545,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schultz, A.K.","contributorId":88983,"corporation":false,"usgs":true,"family":"Schultz","given":"A.K.","email":"","affiliations":[],"preferred":false,"id":457548,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Iverson, S.

A new approach examining this possibility is based on examining the information about many VMS deposits to test statistically if those with associated intrusions have significantly different grades or amounts of metals. A set of 632 VMS deposits with reported grades, tonnages, and information about the observed presence or absence of subvolcanic or plutonic intrusive bodies emplaced at or after VMS mineralization is statistically analyzed.</p><p id=\"sp0015\">Deposits with syn-mineralization or post-mineralization intrusions nearby have higher tonnages than deposits without reported intrusions, but the differences are not statistically significant. When both kinds of intrusions are reported, VMS deposit sizes are significantly higher than in the deposits without any intrusions.

The Elwha River provides a unique opportunity to study the effects of coastal topography on a buoyant plume, because it discharges into the Strait of Juan de Fuca on the western side of its deltaic headland. Here we show that this headland induces flow separation and transient eddies in the tidally dominated currents (O(100</span><span>&nbsp;</span><span>cm/s)), consistent with other headlands in oscillatory flow.

Because of the transient eddies and the location of the river mouth on the headland, flow immediately offshore of the river mouth is directed eastward twice as frequently as it is westward. This results in a buoyant plume that is much more frequently “bent over” toward the east than the west. During bent over plume conditions, the plume was attached to the eastern shoreline while having a distinct, cuspate front along its westernmost boundary. The location of the front was found to be related to the magnitude and direction of local flow during the preceding O(1</span><span>&nbsp;</span><span>h), and increases in alongshore flow resulted in deeper freshwater mixing, stronger baroclinic anomalies, and stronger hugging of the coast. During bent over plume conditions, we observed significant convergence of river plume water toward the frontal boundary within 1</span><span>&nbsp;</span><span>km of the river mouth. These results show how coastal topography can strongly influence buoyant plume behavior, and they should assist with understanding of initial coastal sediment dispersal pathways from the Elwha River during a pending dam removal project.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.csr.2010.11.007","issn":"02784343","usgsCitation":"Warrick, J.A., and Stevens, A.W., 2011, A buoyant plume adjacent to a headland-Observations of the Elwha River plume: Continental Shelf Research, v. 31, no. 2, p. 85-97, https://doi.org/10.1016/j.csr.2010.11.007.","productDescription":"13 p.","startPage":"85","endPage":"97","costCenters":[],"links":[{"id":245573,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217616,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.csr.2010.11.007"}],"country":"United States","state":"Washington","otherGeospatial":"Elwha River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -123.68957519531251,\n              47.87214396888731\n            ],\n            [\n              -123.24462890625,\n              47.87214396888731\n            ],\n            [\n              -123.24462890625,\n              48.188063481211415\n            ],\n            [\n              -123.68957519531251,\n              48.188063481211415\n            ],\n            [\n              -123.68957519531251,\n              47.87214396888731\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"31","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e333e4b0c8380cd45e98","chorus":{"doi":"10.1016/j.csr.2010.11.007","url":"http://dx.doi.org/10.1016/j.csr.2010.11.007","publisher":"Elsevier BV","authors":"Warrick Jonathan A., Stevens Andrew W.","journalName":"Continental Shelf Research","publicationDate":"2/2011"},"contributors":{"authors":[{"text":"Warrick, Jonathan A. 0000-0002-0205-3814 jwarrick@usgs.gov","orcid":"https://orcid.org/0000-0002-0205-3814","contributorId":167736,"corporation":false,"usgs":true,"family":"Warrick","given":"Jonathan","email":"jwarrick@usgs.gov","middleInitial":"A.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":457003,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stevens, Andrew W. 0000-0003-2334-129X astevens@usgs.gov","orcid":"https://orcid.org/0000-0003-2334-129X","contributorId":139313,"corporation":false,"usgs":true,"family":"Stevens","given":"Andrew","email":"astevens@usgs.gov","middleInitial":"W.","affiliations":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":457002,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Plant and ground-cover data inform managers about forage availability, plant community composition and structure, and risk of runoff and erosion. The spatial arrangement of plants at a site in addition to the percent of the ground that is covered by plants is an important determinant of erosion potential. Vertical vegetation structure can be monitored by capturing data on maximum plant height at each stick location.

This paper summarizes the development criteria and the products that made the ShakeOut Scenario so widely known and used, and it provides some suggestions for future improvements. ?? 2011, Earthquake Engineering Research Institute.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Earthquake Spectra","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1193/1.3574445","issn":"87552930","usgsCitation":"Perry, S., Jones, L., and Cox, D., 2011, Developing a Scenario for widespread use: Best practices, lessons learned: Earthquake Spectra, v. 27, no. 2, p. 263-272, https://doi.org/10.1193/1.3574445.","startPage":"263","endPage":"272","numberOfPages":"10","costCenters":[],"links":[{"id":475352,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://resolver.caltech.edu/CaltechAUTHORS:20110926-092227680","text":"External Repository"},{"id":244869,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216966,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1193/1.3574445"}],"volume":"27","issue":"2","noUsgsAuthors":false,"publicationDate":"2011-05-01","publicationStatus":"PW","scienceBaseUri":"505a0007e4b0c8380cd4f54b","contributors":{"authors":[{"text":"Perry, S.","contributorId":70340,"corporation":false,"usgs":true,"family":"Perry","given":"S.","email":"","affiliations":[],"preferred":false,"id":444265,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jones, L.","contributorId":26084,"corporation":false,"usgs":true,"family":"Jones","given":"L.","affiliations":[],"preferred":false,"id":444264,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cox, D.","contributorId":72599,"corporation":false,"usgs":true,"family":"Cox","given":"D.","affiliations":[],"preferred":false,"id":444266,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

However, most assessments have addressed individual sites or regional taxon pools, with few comparisons of differences in assemblage composition within or among regions. We examined the effects of anthropogenic disturbance on local richness (α diversity) and species turnover (β diversity) of benthic macroinvertebrates in small streams within and between 2 ecoregions (Northern Piedmont vs Southeastern Plains ecoregions) of the Patuxent River basin (Maryland, USA). Regional species pools did not differ between ecoregions (Piedmont  =  166 taxa, Plains  =  162 taxa); however, local richness was lower in the Plains (mean  =  17.4 taxa/stream) compared to the Piedmont (mean  =  22.2 taxa/stream). When streams were categorized into disturbance classes (low, medium, high), local richness did not differ among categories for either region. However, at the entire Patuxent scale, local richness tended to decrease with % impervious cover in a watershed. Variation in species composition, analyzed with nonmetric multidimensional scaling (nMDS), differed significantly between Piedmont and Plains streams, and Plains streams had higher β diversity than Piedmont streams. When partitioned by disturbance category and region, β diversity differed only between the low-disturbance sites (Plains &gt; Piedmont). Relationships between β diversity and environmental variables varied by region. β diversity was weakly negatively related to % row-crop cover in a watershed at the entire Patuxent scale. For the Piedmont region, β diversity tended to decrease with % forest, % pasture, and % row-crop cover in a watershed. Such negative relationships between β diversity and landuse variables indicate a possible homogenization of the assemblage. The incongruence between diversity measures and composition measures, together with differing effects of anthropogenic land use on β diversity in the 2 regions, emphasizes the need to incorporate both α and β diversity and regional environmental factors in conservation/land management studies.</span></p>","language":"English","publisher":"The University of Chicago Press Journals","doi":"10.1899/09-112.1","issn":"08873593","usgsCitation":"Maloney, K., Munguia, P., and Mitchell, R., 2011, Anthropogenic disturbance and landscape patterns affect diversity patterns of aquatic benthic macroinvertebrates: Journal of the North American Benthological Society, v. 30, no. 1, p. 284-295, https://doi.org/10.1899/09-112.1.","productDescription":"12 p.","startPage":"284","endPage":"295","costCenters":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"links":[{"id":245835,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217863,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1899/09-112.1"}],"country":"United States","state":"Maryland","otherGeospatial":"Patuxent Watershed","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -76.35498046875,\n              38.11727165830543\n            ],\n            [\n              -76.2615966796875,\n              38.14751758025121\n            ],\n            [\n              -76.4044189453125,\n              38.406253794852674\n            ],\n            [\n              -76.6241455078125,\n              38.955137225429574\n            ],\n            [\n              -76.827392578125,\n              38.997841307500714\n            ],\n            [\n              -76.904296875,\n              38.8782049970615\n            ],\n            [\n              -76.8658447265625,\n              38.59540719940386\n            ],\n            [\n              -76.629638671875,\n              38.3287297527893\n            ],\n            [\n              -76.35498046875,\n              38.11727165830543\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"30","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ec59e4b0c8380cd491f5","contributors":{"authors":[{"text":"Maloney, K.O. 0000-0003-2304-0745","orcid":"https://orcid.org/0000-0003-2304-0745","contributorId":105414,"corporation":false,"usgs":true,"family":"Maloney","given":"K.O.","affiliations":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"preferred":false,"id":458404,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Munguia, P.","contributorId":30855,"corporation":false,"usgs":true,"family":"Munguia","given":"P.","email":"","affiliations":[],"preferred":false,"id":458403,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mitchell, R.M.","contributorId":28721,"corporation":false,"usgs":true,"family":"Mitchell","given":"R.M.","email":"","affiliations":[],"preferred":false,"id":458402,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Gonadal intersex and other evidence of reproductive disruption were previously identified in white suckers (<i>Catostomus commersoni</i>) in Boulder Creek downstream from this WWTP effluent outfall. Fish were exposed within a mobile flow-through exposure laboratory in July 2005 and August 2006 to WWTP effluent (EFF), Boulder Creek water (REF), or mixtures of EFF and REF for up to 28 days. Primary (sperm abundance) and secondary (nuptial tubercles and dorsal fat pads) sex characteristics were demasculinized within 14 days of exposure to 50% and 100% EFF. Vitellogenin was maximally elevated in both 50% and 100% EFF treatments within 7 days and significantly elevated by 25% EFF within 14 days. The steroidal estrogens 17β-estradiol, estrone, estriol, and 17α-ethynylestradiol, as well as estrogenic alkylphenols and bisphenol A were identified within the EFF treatments and not in the REF treatment. These results support the hypothesis that the reproductive disruption observed in this watershed is due to endocrine-active chemicals in the WWTP effluent.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/j.aquatox.2011.02.007","usgsCitation":"Vajda, A., Barber, L.B., Gray, J.L., Lopez, E., Bolden, A., Schoenfuss, H., and Norris, D., 2011, Demasculinization of male fish by wastewater treatment plant effluent: Aquatic Toxicology, v. 103, no. 3-4, p. 213-221, https://doi.org/10.1016/j.aquatox.2011.02.007.","productDescription":"9 p.","startPage":"213","endPage":"221","numberOfPages":"9","ipdsId":"IP-013216","costCenters":[{"id":452,"text":"National Water Quality Laboratory","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true},{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"links":[{"id":243345,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","city":"Boulder","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -105.2021598815918,\n              40.03839224384298\n            ],\n            [\n              -105.17572402954102,\n              40.03839224384298\n            ],\n            [\n              -105.17572402954102,\n              40.05692083088936\n            ],\n            [\n              -105.2021598815918,\n              40.05692083088936\n            ],\n            [\n              -105.2021598815918,\n              40.03839224384298\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"103","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fe79e4b0c8380cd4ed49","contributors":{"authors":[{"text":"Vajda, A.M.","contributorId":35961,"corporation":false,"usgs":true,"family":"Vajda","given":"A.M.","affiliations":[],"preferred":false,"id":448930,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barber, Larry B. 0000-0002-0561-0831 lbbarber@usgs.gov","orcid":"https://orcid.org/0000-0002-0561-0831","contributorId":921,"corporation":false,"usgs":true,"family":"Barber","given":"Larry","email":"lbbarber@usgs.gov","middleInitial":"B.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":779279,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gray, James L. 0000-0002-0807-5635 jlgray@usgs.gov","orcid":"https://orcid.org/0000-0002-0807-5635","contributorId":1253,"corporation":false,"usgs":true,"family":"Gray","given":"James","email":"jlgray@usgs.gov","middleInitial":"L.","affiliations":[{"id":452,"text":"National Water Quality Laboratory","active":true,"usgs":true},{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true},{"id":5046,"text":"Branch of Analytical Serv (NWQL)","active":true,"usgs":true}],"preferred":true,"id":779280,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lopez, E.M.","contributorId":107520,"corporation":false,"usgs":true,"family":"Lopez","given":"E.M.","email":"","affiliations":[],"preferred":false,"id":448935,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bolden, A.M.","contributorId":91707,"corporation":false,"usgs":true,"family":"Bolden","given":"A.M.","email":"","affiliations":[],"preferred":false,"id":448933,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Schoenfuss, H.L.","contributorId":103877,"corporation":false,"usgs":true,"family":"Schoenfuss","given":"H.L.","affiliations":[],"preferred":false,"id":448934,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Norris, D.O.","contributorId":58475,"corporation":false,"usgs":true,"family":"Norris","given":"D.O.","email":"","affiliations":[],"preferred":false,"id":448931,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}
