Scientific research on the global carbon cycle has emerged as a high priority in biogeochemistry, climate studies, and global change policy. The emission of carbon dioxide (CO2) from fossil fuel combustion is a dominant driver of the current net carbon fluxes between the land, the oceans, and the atmosphere, and it is a key contributor to the rise in modern radiative forcing. Contrary to a commonly held perception, our quantitative knowledge about these emissions is insufficient to satisfy current scientific and policy needs. A more highly spatially and temporally resolved quantification of the social and economic drivers of fossil fuel combustion, and the resulting CO2 emissions, is essential to supporting scientific and policy progress. In this article, a new community of emissions researchers called the CO2 Fossil Fuel Emission Effort (CO2FFEE) outlines a research agenda to meet the need for improved fossil fuel CO2 emissions information and solicits comment from the scientific community and research agencies.

Such maps have been lacking, but recent computer technology and software offer promise in the capture and display of diverse marine data. Continental margins contain landforms which provide a variety of important functions and contain important sedimentary records. Some shelf areas also contain deposits regarded as potential aggregate resources. Because proper management of coastal and offshore areas is increasingly important, knowledge of the framework geology and marine processes is critical. Especially valuable are comprehensive and integrated digital databases based on high-quality information from original sources. Products of interest are GIS maps containing thematic information, such as sediment character and texture. These products are useful to scientists modeling nearshore and shelf processes as well as planners and managers. The U.S. Geological Survey is leading a national program to gather a variety of extant marine geologic data into the usSEABED database system. This provides centralized, integrated marine geologic data collected over the past 50 years. To date, over 340,000 sediment data points from the U.S. reside in usSEABED, which combines an array of physical data and analytical and descriptive information about the sea floor and are available to the marine community through three USGS data reports for the Atlantic, Gulf of Mexico, and Pacific published in 2006, and the project web sites: (http://woodshole.er.usg s.gov/project-pages/aggregates/ and http://walrus.wr.usgs.gov/usseabed/)","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Coastal Sediments '07 - Proceedings of 6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes","conferenceDate":"May 13-17, 2007","conferenceLocation":"New Orleans, LA","language":"English","publisher":"American Society of Civil Engineers","doi":"10.1061/40926(239)194","isbn":"0784409269; 9780784409268","usgsCitation":"Williams, S., Bliss, J.D., Arsenault, M., Jenkins, C., and Goff, J., 2007, Geologic characterization of shelf areas using usSEABED for GIS mapping, modeling processes and assessing marine sand and gravel resources, in Coastal Sediments '07 - Proceedings of 6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes, New Orleans, LA, May 13-17, 2007, p. 2473-2486, https://doi.org/10.1061/40926(239)194.","productDescription":"14 p.","startPage":"2473","endPage":"2486","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":239870,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","noUsgsAuthors":false,"publicationDate":"2012-04-26","publicationStatus":"PW","scienceBaseUri":"505a1937e4b0c8380cd558f0","contributors":{"authors":[{"text":"Williams, S.J.","contributorId":85203,"corporation":false,"usgs":true,"family":"Williams","given":"S.J.","email":"","affiliations":[],"preferred":false,"id":432521,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bliss, J.

The deltaic landscape contains vegetated marshes, tidal flats, circuitous channels, and other features that frictionally dissipate waves propagating through the system. Direct forcing by local wind stress over the surface of the estuary is minimal, owing to the lack of significant fetch due to landscape features of the estuary. Atmospheric forcing occurs almost entirely through remote forcing, where alongshore winds facilitate estuary-shelf exchange through coastal Ekman convergence. The highly frictional nature of the deltaic landscape causes the estuary to act as a low-pass filter to remote atmospheric forcing, where high-frequency, coastally-induced fluctuations are significantly damped, and the damping increases with distance from the estuary mouth. During spring, when substantial quantities of controlled Mississippi River inputs (q¯ = 62 m3 s¯ 1) are discharged into the estuary, upper estuary subtidal sea levels are forced by a combination of river and remote atmospheric forcings, while river effects are less clear downestuary. During autumn (q¯ = 7 m3 s-1) sea level variability throughout the estuary is governed entirely by coastal variations at the marine boundary. A frequency-dependent analytical model, previously used to describe sea level dynamics forced by local wind stress and coastal forcing in deeper, less frictional systems, is applied in the shallow Breton Sound estuary. In contrast to deeper systems where coastally-induced fluctuations exhibit little or no frictional attenuation inside the estuary, these fluctuations in the shallow Breton Sound estuary show strong frequency-dependent amplitude reductions that extend well into the subtidal frequency spectrum.

Comparison of marine paleoclimate records that track salinity changes from Asian rivers can help evaluate the coherence of the Indian Ocean monsoon (IOM) with the larger Asian monsoon. Here we present paired Mg/Ca and δ18O data on the planktic foraminifer Globigerinoides ruber (white) from Andaman Sea core RC12-344 that provide records of sea-surface temperature (SST) and δ18O of seawater (δ18Osw) over the past 25,000 years (ka) before present (BP). Age control is based on nine accelerator mass spectrometry (AMS) dates on mixed planktic foraminifera. Mg/Ca-SST data indicate that SST was ∼3 °C cooler during the last glacial maximum (LGM) than the late Holocene. Andaman Sea δ18Osw exhibited higher than present values during the Lateglacial interval ca 19–15 ka BP and briefly during the Younger Dryas ca 12 ka BP. Lower than present δ18Osw values during the BØlling/AllerØd ca 14.5–12.6 ka BP and during the early Holocene ca 10.8–5.5 ka BP are interpreted to indicate lower salinity, reflect some combination of decreased evaporation–precipitation (E–P) over the Andaman Sea and increased Irrawaddy River outflow. Our results are consistent with the suggestion that IOM intensity was stronger than present during the BØlling/AllerØd and early Holocene, and weaker during the late glaciation, Younger Dryas, and the late Holocene. These findings support the hypothesis that rapid climate change during the last deglaciation and Holocene included substantial hydrologic changes in the IOM system that were coherent with the larger Asian monsoon.

Thirty-four fish (33% of those examined) were found to contain food material. Food items were present in 41% of Mohawk River samples and 11% of Hudson River samples; all Hudson River fish containing food were captured in small tributaries above the head of tide. Hudson River fish predominantly consumed zooplankton, while Mohawk River fish consumed benthic aquatic insects in large quantities, including Baetidae, Ephemeridae, and Chironomidae. Using stable isotope analysis and a mixing model, we found that fish collected later in the season had significantly decreased marine-derived C. Condition indices of later-season fish were equal to or greater than those of fish collected earlier in the season. Blueback herring in this system may face increased energy requirements as they migrate farther upstream during spawning runs, and feeding may provide energy subsidies needed to maintain fitness over their expanded migratory range. ??

Two four-story scaled building specimens were tested under quasi-static cyclic lateral loading in longitudinal and transverse directions. The experimental results and supplemental finite element simulations collectively indicate that lightly reinforced structural walls of tunnel form buildings may exhibit brittle flexural failure under seismic action. The global tension/compression couple triggers this failure mechanism by creating pure axial tension in outermost shear-walls. This type of failure takes place due to rupturing of longitudinal reinforcement without crushing of concrete, therefore is of particular interest in emphasizing the mode of failure that is not routinely considered during seismic design of shear-wall dominant structural systems.","language":"English","publisher":"KoreaScience","doi":"10.12989/sem.2007.27.1.099","usgsCitation":"Yuksel, S., and Kalkan, E., 2007, Behavior of tunnel form buildings under quasi-static cyclic lateral loading: Structural Engineering and Mechanics, v. 27, no. 1, p. 99-115, https://doi.org/10.12989/sem.2007.27.1.099.","productDescription":"17 p.","startPage":"99","endPage":"115","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":239705,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"27","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f0a2e4b0c8380cd4a811","contributors":{"authors":[{"text":"Yuksel, S.B.","contributorId":67202,"corporation":false,"usgs":true,"family":"Yuksel","given":"S.B.","email":"","affiliations":[],"preferred":false,"id":432473,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kalkan, E. 0000-0002-9138-9407","orcid":"https://orcid.org/0000-0002-9138-9407","contributorId":8212,"corporation":false,"usgs":true,"family":"Kalkan","given":"E.","affiliations":[],"preferred":false,"id":432472,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70031637,"text":"70031637 - 2007 - Nucularcidae: A new family of palaeotaxodont Ordovician pelecypods (Mollusca) from North America and Australia","interactions":[],"lastModifiedDate":"2012-03-12T17:21:13","indexId":"70031637","displayToPublicDate":"2007-01-01T00:00:00","publicationYear":"2007","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1168,"text":"Canadian Journal of Earth Sciences","active":true,"publicationSubtype":{"id":10}},"title":"Nucularcidae: A new family of palaeotaxodont Ordovician pelecypods (Mollusca) from North America and Australia","docAbstract":"The new Ordovician palaeotaxodont family Nucularcidae and the new genus Nucularca are described.

We tested the effects of species, site, sex, year, and date on total mercury concentrations in blood of pre-breeding adult birds and used radio telemetry to determine space use and sites of dietary mercury exposure. We collected blood from 373 avocets and 157 stilts from February to April in 2005 and 2006, radio-marked and tracked 115 avocets and 94 stilts, and obtained 2393 avocet and 1928 stilt telemetry locations. Capture site was the most important factor influencing mercury concentrations in birds, followed by species and sex. Mercury concentrations were higher in stilts (geometric mean: 1.09 μg g− 1 wet weight [ww]) than in avocets (0.25 μg g− 1 ww) and males (stilts: 1.32 μg g− 1 ww; avocets: 0.32 μg g− 1 ww) had higher levels than females (stilts: 1.15 μg g− 1 ww; avocets: 0.21 μg g− 1 ww). Mercury concentrations were highest for both species at the southern end of San Francisco Bay, especially in salt pond A8 (stilts: 3.31 μg g− 1 ww; avocets: 0.58 μg g− 1 ww). Radio telemetry data showed that birds had strong fidelity to their capture site. Avocets primarily used salt ponds, tidal marshes, tidal flats, and managed marshes, whereas stilts mainly used salt ponds, managed marshes, and tidal marshes. Our results suggest that variation in blood mercury concentrations among sites was attributed to differences in foraging areas, and species differences in habitat use and foraging strategies may increase mercury exposure in stilts more than avocets.

A well-preserved sequence of latero-frontal moraines in the drainage indicates that outlet glaciers advanced beyond the mountain front and coalesced on the piedmont. Glacial deposits in the Bear River drainage provide a unique setting where both 10Be cosmogenic surface-exposure dating of moraine boulders and 14C dating of sediment in Bear Lake downstream of the glaciated area set age limits on the timing of glaciation. Limiting 14C ages of glacial flour in Bear Lake (corrected to calendar years using CALIB 5.0) indicate that ice advance began at 32 ka and culminated at about 24 ka. Based on a Bayesian statistical analysis of cosmogenic surface-exposure ages from two areas on the terminal moraine complex, the Bear River glacier began its final retreat at about 18.7 to 18.1 ka, approximately coincident with the start of deglaciation elsewhere in the central Rocky Mountains and many other alpine glacial localities worldwide. Unlike valleys of the southwestern Uinta Mountains, deglaciation of the Bear River drainage began prior to the hydrologie fall of Lake Bonneville from the Provo shoreline at about 16 ka. ?? 2007 Regents of the University of Colorado.","largerWorkTitle":"Arctic, Antarctic, and Alpine Research","language":"English","doi":"10.1657/1523-0430(06-089)[LAABS]2.0.CO;2","issn":"15230430","usgsCitation":"Laabs, B., Munroe, J.S., Rosenbaum, J.G., Refsnider, K., Mickelson, D., Singer, B.S., and Caffee, M., 2007, Chronology of the last glacial maximum in the upper Bear River Basin, Utah, in Arctic, Antarctic, and Alpine Research, v. 39, no. 4, p. 537-548, https://doi.org/10.1657/1523-0430(06-089)[LAABS]2.0.CO;2.","startPage":"537","endPage":"548","numberOfPages":"12","costCenters":[],"links":[{"id":477273,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://www.bioone.org/doi/10.1657/1523-0430%2806-089%29%5BLAABS%5D2.0.CO%3B2","text":"External Repository"},{"id":240150,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212634,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1657/1523-0430(06-089)[LAABS]2.0.CO;2"}],"volume":"39","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f5f9e4b0c8380cd4c516","contributors":{"authors":[{"text":"Laabs, B.J.C.","contributorId":44353,"corporation":false,"usgs":true,"family":"Laabs","given":"B.J.C.","email":"","affiliations":[],"preferred":false,"id":432442,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Munroe, Jeffrey S.","contributorId":24175,"corporation":false,"usgs":false,"family":"Munroe","given":"Jeffrey","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":432441,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rosenbaum, J.

Although traditional traps can be effective when conditions are ideal, they are often unable to withstand high-discharge events in streams containing a large amount of debris or sandy substrates. We created a rotary-screw trap and resistance board weir hybrid design that we evaluated along with a tripod weir and box trap, both in a 6.1-m-wide flume and in the field. The new design outperformed the tripod weir in both situations. The tripod weir failed in 10 min in the flume trial, whereas the new design was still operating at the conclusion of an 8-h trial under the same conditions. The new design operated continuously in the field during a high-discharge event that caused the tripod weir to fail. The new design also required less frequent cleaning than the tripod weir. The trap efficiency of the new design was estimated by using passive integrated transponder (PIT) tag antennas and radiotelemetry. The trap was 80% efficient (n = 40) in capturing migrating PIT-tagged individuals detected at an antenna upstream of the trap and 87.5% efficient (n = 48) at recapturing fish that had been tagged and released upstream. With its high efficiency and increased resiliency over the tripod weir, the new trap design will benefit management and research efforts in streams where traditional traps are unsuitable. ??

However, the ability to predict the influence of annual and inter-annual events on a regional scale still remains limited. High-resolution hourly data from 6 National Oceanographic and Atmospheric Administration (NOAA) buoys deployed since the early 1980's off Central California were analyzed to improve our understanding of spatial and temporal variability of oceanographic and meteorologic forcing along the coastline. Seasonal to inter-annual trends in wave height, wave period, sea level barometric pressure, sea-surface temperature, and wind direction were identified, as were significant departures in these trends during El Niño and La Niña periods. The results suggest there are increasing wave heights and wave periods, decreasing sea level barometric pressures and variability in sea-surface temperatures, and increasingly variable winds off Central California between 1980 and 2002. The impact of these climatic trends on coastal physical, geological and biologic processes will also be addressed.","language":"English","publisher":"Elsevier","doi":"10.1016/j.jmarsys.2007.02.008","issn":"09247963","usgsCitation":"Wingfield, D., and Storlazzi, C., 2007, Spatial and temporal variability in oceanographic and meteorologic forcing along Central California and its implications on nearshore processes: Journal of Marine Systems, v. 68, no. 3-4, p. 457-472, https://doi.org/10.1016/j.jmarsys.2007.02.008.","productDescription":"16 p.","startPage":"457","endPage":"472","numberOfPages":"16","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":240114,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","volume":"68","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b944fe4b08c986b31a9cc","contributors":{"authors":[{"text":"Wingfield, D.K.","contributorId":16656,"corporation":false,"usgs":true,"family":"Wingfield","given":"D.K.","email":"","affiliations":[],"preferred":false,"id":432435,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Storlazzi, C.

Along each 2-D profile a velocity–depth function has been digitised at 5 km intervals. These 1-D velocity functions were mapped into three dimensions using ordinary kriging with weights determined to minimise the difference between digitised and interpolated values. An analysis of variograms of the digitised data suggested a radial isotropic weighting scheme was most appropriate. Horizontal dimensions of the model cells are optimised at 40 × 40 km and the vertical dimension at 1 km. The resulting model provides a higher resolution image of the 3-D variation in seismic velocity structure of the UK, Ireland and surrounding areas than existing models. The construction of the model through kriging allows the uncertainty in the velocity structure to be assessed. This uncertainty indicates the high density of data required to confidently interpolate the crustal velocity structure, and shows that for this region the velocity is poorly constrained for large areas away from the input data.

Sixty-two radio-tagged adult females were tracked for 30-180 days to locate and describe their nest sites. In addition, the Laysan Teal were surveyed daily during the breeding season, and 331 individually colour-ringed females were marked to identify new broods and timing of incubation initiation. Temperature, rainfall, and abundance of Brine Flies (Scatella sexnotata, an important prey) were measured in all years. Females nested on average 213 m (s.e. ?? 37 m) from the lake basin primarily in Eragrostis variablis, a native bunch grass with > 75% cover. The first observation of nesting in marine debris by Laysan Teal was reported. The initiation of incubation, at the start of the breeding season each year, varied from December to July, and differed significantly between years. Brine Fly abundance, temperature, and rainfall also varied significantly between years. The earlier the Brine Fly abundance peaked, the longer the duration of the breeding season. The length of the breeding season, measured as the number of days between the first and last clutches, varied from 83-192 days (mean 116 ?? 14 days). Annual brood production was positively correlated with spring peak abundance of Brine Flies. There was some evidence that it was negatively correlated with the number of adult females in the population. Rainfall, temperature, prey abundance, and the density of other birds on Laysan Island are likely to interact in influencing Laysan Teal's variable nesting phenology and productivity. ??

Food resources for terrestrial birds often are closely related to vegetation structure and composition. Identification of plant species important in supporting food resources may facilitate vegetation management to achieve objectives for providing bird habitat. We used fecal analysis to describe the diet of adult Wilson's Warblers (Wilsonia pusilla) that foraged in the understory of Douglas-fir (Pseudotsuga menziesii) forests in western Oregon during the breeding season. We sampled arthropods at the same sites where diet data were collected, and compared abundance and biomass of prey among seven common shrub species. Wilson's Warblers ate more caterpillars (Lepidoptera larvae), flies (Diptera), beetles (Coleoptera), and Homoptera than expected based on availability. Deciduous shrubs supported higher abundances of arthropod taxa and size classes used as prey by Wilson's Warblers than did evergreen shrubs. The development and maintenance of deciduous understory vegetation in conifer forests of the Pacific Northwest may be fundamental for conservation of food webs that support breeding Wilson's Warblers and other shrub-associated, insectivorous songbirds.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wilson Journal of Ornithology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1676/06-056.1","issn":"15594491","usgsCitation":"Hagar, J., Dugger, K., and Starkey, E., 2007, Arthropod prey of Wilson's Warblers in the understory of Douglas-fir forests: Wilson Journal of Ornithology, v. 119, no. 4, p. 533-546, https://doi.org/10.1676/06-056.1.","startPage":"533","endPage":"546","numberOfPages":"14","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":240003,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212510,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1676/06-056.1"}],"volume":"119","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059eda6e4b0c8380cd49917","contributors":{"authors":[{"text":"Hagar, J.C.","contributorId":46208,"corporation":false,"usgs":true,"family":"Hagar","given":"J.C.","affiliations":[],"preferred":false,"id":432407,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dugger, K.M.","contributorId":25729,"corporation":false,"usgs":true,"family":"Dugger","given":"K.M.","email":"","affiliations":[],"preferred":false,"id":432406,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Starkey, E.

We studied the population genetics of feral cats on Hawai'i Island by microsatellite analysis to evaluate genetic diversity and population structure, assess gene flow and connectivity among three populations, identify potential source populations, characterise population dynamics, and evaluate sex-biased dispersal. High genetic diversity, low structure, and high number of migrants per generation supported high gene flow that was not limited spatially. Migration rates revealed that most migration occurred out of West Mauna Kea. Effective population size estimates indicated increasing cat populations despite control efforts. Despite high gene flow, relatedness estimates declined significantly with increased geographic distance and Bayesian assignment tests revealed the presence of three population clusters. Genetic structure and relatedness estimates indicated male-biased dispersal, primarily from Mauna Kea, suggesting that this population should be targeted for control. However, recolonisation seems likely, given the great dispersal ability that may not be inhibited by barriers such as lava flows. Genetic monitoring will be necessary to assess the effectiveness of future control efforts. Management of other invasive species may benefit by employing these population genetic tools. ??

Agriculture and other land uses can have a substantial effect on grassland cover that varies regionally depending on the primary driving forces of change. In order to better understand change, the rates, types, and causes of land conversion were examined for 1973, 1980, 1986, 1992, and 2000 using Landsat satellite data and a statistical sampling strategy. The overall estimated rate of land-cover change between 1973 and 2000 was 7.4% in the Northwestern Great Plains and 11.5% in the Western High Plains. Trends in both ecoregions have similarities, although the dynamics of change differ temporally depending on driving forces. Between 1973 and 1986, grassland cover declined when economic opportunity drove an expansion of agriculture. Between 1986 and 2000, grassland expanded as public policy and a combination of socioeconomic factors drove a conversion from agriculture to grassland. ?? 2007 Copyright by the Center for Great Plains Studies, University of Nebraska-Lincoln.","largerWorkTitle":"Great Plains Research","language":"English","issn":"10525165","usgsCitation":"Drummond, M., 2007, Regional dynamics of grassland change in the western Great Plains, in Great Plains Research, v. 17, no. 2, p. 133-144.","startPage":"133","endPage":"144","numberOfPages":"12","costCenters":[],"links":[{"id":239937,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"17","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a4c1e4b0e8fec6cdbc4b","contributors":{"authors":[{"text":"Drummond, M.A.","contributorId":53602,"corporation":false,"usgs":true,"family":"Drummond","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":432395,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70031620,"text":"70031620 - 2007 - Survey of selected pathogens and blood parameters of northern yellowstone elk: Wolf sanitation effect implications","interactions":[],"lastModifiedDate":"2017-09-08T10:25:04","indexId":"70031620","displayToPublicDate":"2007-01-01T00:00:00","publicationYear":"2007","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":737,"text":"American Midland Naturalist","active":true,"publicationSubtype":{"id":10}},"title":"Survey of selected pathogens and blood parameters of northern yellowstone elk: Wolf sanitation effect implications","docAbstract":"The restoration or conservation of predators could reduce seroprevalences of certain diseases in prey if predation selectively removes animals exhibiting clinical signs.

Though we did not detect an overall strong predation effect through reduced disease seroprevalence using retrospective comparisons with sparse data, our reference values will facilitate future assessments of this issue.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Midland Naturalist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1674/0003-0031(2007)158[369:SOSPAB]2.0.CO;2","issn":"00030031","usgsCitation":"Barber-Meyer, S., White, P., and Mech, L., 2007, Survey of selected pathogens and blood parameters of northern yellowstone elk: Wolf sanitation effect implications: American Midland Naturalist, v. 158, no. 2, p. 369-381, https://doi.org/10.1674/0003-0031(2007)158[369:SOSPAB]2.0.CO;2.","productDescription":"13 p.","startPage":"369","endPage":"381","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":239902,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212418,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1674/0003-0031(2007)158[369:SOSPAB]2.0.CO;2"}],"geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -111.15966796875,\n 43.683763524273346\n ],\n [\n -109.259033203125,\n 43.683763524273346\n ],\n [\n -109.259033203125,\n 45.1510532655634\n ],\n [\n -111.15966796875,\n 45.1510532655634\n ],\n [\n -111.15966796875,\n 43.683763524273346\n ]\n ]\n ]\n }\n }\n ]\n}","volume":"158","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba299e4b08c986b31f800","contributors":{"authors":[{"text":"Barber-Meyer, S.

A ranking of 169 volcanoes in the United States and the Commonwealth of the Northern Mariana Islands (U.S. volcanoes) is presented based on scores assigned for various hazard and exposure factors. Fifteen factors define the hazard: Volcano type, maximum known eruptive explosivity, magnitude of recent explosivity within the past 500 and
