Conservation efforts for D. couperi have been hindered, in part, because of informational gaps regarding the species, including a lack of data on population ecology and estimates of demographic parameters such as survival. We conducted a 2- year radiotelemetry study of D. couperi on Fort Stewart Military Reservation and adjacent private lands located in southeastern Georgia to assess individual characteristics associated with probability of survival. We used known-fate modeling to estimate survival, and an information-theoretic approach, based on a priori hypotheses, to examine intraspecific differences in survival probabilities relative to individual covariates (sex, size, size standardized by sex, and overwintering location). Annual survival in 2003 and 2004 was 0.89 (95% CI = 0.73-0.97, n = 25) and 0.72 (95% CI = 0.52-0.86; n = 27), respectively. Results indicated that body size, standardized by sex, was the most important covariate determining survival of adult D. couperi, suggesting lower survival for larger individuals within each sex. We are uncertain of the mechanisms underlying this result, but possibilities may include greater resource needs for larger individuals within each sex, necessitating larger or more frequent movements, or a population with older individuals. Our results may also have been influenced by analysis limitations because of sample size, other sources of individual variation, or environmental conditions. ?? 2009 by The Herpetologists' League, Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Herpetologica","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1655/08-004R1.1","issn":"00180831","usgsCitation":"Hyslop, N., Meyers, J., Cooper, R., and Norton, T., 2009, Survival of radio-implanted drymarchon couperi (Eastern Indigo Snake) in relation to body size and sex: Herpetologica, v. 65, no. 2, p. 199-206, https://doi.org/10.1655/08-004R1.1.","startPage":"199","endPage":"206","numberOfPages":"8","costCenters":[],"links":[{"id":215389,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1655/08-004R1.1"},{"id":243188,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"65","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba2dae4b08c986b31f9f0","contributors":{"authors":[{"text":"Hyslop, N.L.","contributorId":22066,"corporation":false,"usgs":true,"family":"Hyslop","given":"N.L.","email":"","affiliations":[],"preferred":false,"id":449201,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Meyers, J.M.","contributorId":54307,"corporation":false,"usgs":true,"family":"Meyers","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":449202,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cooper, R.J.","contributorId":89077,"corporation":false,"usgs":true,"family":"Cooper","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":449204,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Norton, Terry M.","contributorId":71020,"corporation":false,"usgs":true,"family":"Norton","given":"Terry M.","affiliations":[],"preferred":false,"id":449203,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Recent research has demonstrated that wildlife-vehicle-collisions (WVC) involving carnivores are modulated by temporal and spatial factors. Thus, we investigated road mortality on a guild of small and medium-sized carnivores in southern Portugal using road-kill data obtained from a systematic 36 months monitoring period along highways (260 km) and national roads (314 km) by addressing the following questions: (a) which species and age class are most vulnerable to WVC? (b) are there temporal and/or spatial patterns in road-kill? and (c) which life-history and/or spatial factors influence the likelihood of collisions? We recorded a total of 806 carnivore casualties, which represented an average of 47 ind./100 km/year. Red fox and stone marten had the highest mortality rates. Our findings highlight three key messages: (1) the majority of road-killed individuals were adults of common species; (2) all carnivores, except genets, were more vulnerable during specific life-history phenological periods: higher casualties were observed when red fox and stone marten were provisioning young, Eurasian badger casualties occurred more frequently during dispersal, and higher Egyptian mongoose mortality occurred during the breeding period; and (3) modeling demonstrated that favorable habitat, curves in the road, and low human disturbance were major contributors to the deadliest road segments. Red fox carcasses were more likely to be found on road sections with passages distant from urban areas. Conversely, stone marten mortalities were found more often on national roads with high of cork oak woodland cover; Egyptian mongoose and genet road-kills were found more often on road segments close to curves. Based on our results, two key mitigation measures should help to reduce WVC in Portugal. The first involves the improvement of existing crossings with buried and small mesh size fence to guide the individuals towards to the passages, in road segments with high traffic volume (>1200 vehicles/night) and located in preferred carnivore habitats. The second mitigation involves cutting or removal of dense vegetation in verges of road segments with curves to aid motorists in seeing animals about to cross. ?? 2008 Elsevier Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.biocon.2008.10.026","issn":"00063","usgsCitation":"Grilo, C., Bissonette, J., and Santos-Reis, M., 2009, Spatial-temporal patterns in Mediterranean carnivore road casualties: Consequences for mitigation: Biological Conservation, v. 142, no. 2, p. 301-313, https://doi.org/10.1016/j.biocon.2008.10.026.","startPage":"301","endPage":"313","numberOfPages":"13","costCenters":[],"links":[{"id":213988,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.biocon.2008.10.026"},{"id":241670,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"142","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b94c0e4b08c986b31ac2b","contributors":{"authors":[{"text":"Grilo, C.","contributorId":89362,"corporation":false,"usgs":true,"family":"Grilo","given":"C.","email":"","affiliations":[],"preferred":false,"id":438016,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bissonette, J.A.","contributorId":21498,"corporation":false,"usgs":true,"family":"Bissonette","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":438014,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Santos-Reis, M.","contributorId":58108,"corporation":false,"usgs":true,"family":"Santos-Reis","given":"M.","email":"","affiliations":[],"preferred":false,"id":438015,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

This test site, which was previously mapped in the field, is chiefly composed of Late Cenozoic cinder cones, lava flows, and alluvium perched on Permian limestone of the Kaibab Formation. Faulting and folding has deformed the older rocks and some of the volcanic materials, and fluvial erosion has carved drainage systems and deposited alluvium. These geologic materials and their formational and modificational histories are similar to those for regions of the Martian surface. We independently prepared four geologic maps using topographic and image data at resolutions that mimic those that are commonly used to map the geology of Mars (where consideration was included for the fact that Martian features such as lava flows are commonly much larger than their terrestrial counterparts). We primarily based our map units and stratigraphic relations on geomorphology, color contrasts, and cross-cutting relationships. Afterward, we compared our results with previously published field-based mapping results, including detailed analyses of the stratigraphy and of the spatial overlap and proximity of the field-based vs. remote-based (photogeologic) map units, contacts, and structures. Results of these analyses provide insights into how to optimize the photogeologic mapping of Mars (and, by extension, other remotely observed planetary surfaces). We recommend the following: (1) photogeologic mapping as an excellent approach to recovering the general geology of a region, along with examination of local, high-resolution datasets to gain insights into the complexity of the geology at outcrop scales; (2) delineating volcanic vents and lava-flow sequences conservatively and understanding that flow abutment and flow overlap are difficult to distinguish in remote data sets; (3) taking care to understand that surficial materials (such as alluvium and volcanic ash deposits) are likely to be under-mapped yet are important because they obscure underlying units and contacts; (4) where possible, mapping multiple contact and structure types based on their varying certainty and exposure that reflect the perceived accuracy of the linework; (5) reviewing the regional context and searching for evidence of geologic activity that may have affected the map area yet for which evidence within the map area may be absent; and (6) for multi-authored maps, collectively analyzing the mapping relations, approaches, and methods throughout the duration of the mapping project with the objective of achieving a solid, harmonious product.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Planetary and Space Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.pss.2008.06.012","issn":"00320633","usgsCitation":"Tanaka, K.L., Skinner, J., Crumpler, L.S., and Dohm, J.M., 2009, Assessment of planetary geologic mapping techniques for Mars using terrestrial analogs: The SP Mountain area of the San Francisco Volcanic Field, Arizona: Planetary and Space Science, v. 57, no. 5-6, p. 510-532, https://doi.org/10.1016/j.pss.2008.06.012.","productDescription":"23 p.","startPage":"510","endPage":"532","numberOfPages":"23","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":243523,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arizona","otherGeospatial":"San Francisco Volcanic Field","volume":"57","issue":"5-6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ee48e4b0c8380cd49c8c","contributors":{"authors":[{"text":"Tanaka, Kenneth L. ktanaka@usgs.gov","contributorId":610,"corporation":false,"usgs":true,"family":"Tanaka","given":"Kenneth","email":"ktanaka@usgs.gov","middleInitial":"L.","affiliations":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"preferred":true,"id":447822,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Skinner, James A. 0000-0002-3644-7010 jskinner@usgs.gov","orcid":"https://orcid.org/0000-0002-3644-7010","contributorId":3187,"corporation":false,"usgs":true,"family":"Skinner","given":"James A.","email":"jskinner@usgs.gov","affiliations":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"preferred":true,"id":447823,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Crumpler, Larry S.","contributorId":196268,"corporation":false,"usgs":false,"family":"Crumpler","given":"Larry","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":447824,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dohm, James M.","contributorId":83610,"corporation":false,"usgs":true,"family":"Dohm","given":"James","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":447825,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Understanding the spatial distributions of these new diseases is important for disease management and policy makers; however, the data are complicated by heterogeneities across host classes, sampling variance, sampling biases, and the space-time epidemic process. Ignoring these issues can lead to false conclusions or obscure important patterns in the data, such as spatial variation in disease prevalence. Here, we applied hierarchical Bayesian disease mapping methods to account for risk factors and to estimate spatial and temporal patterns of infection by chronic wasting disease (CWD) in white-tailed deer (Odocoileus virginianus) of Wisconsin, USA. We found significant heterogeneities for infection due to age, sex, and spatial location. Infection probability increased with age for all young deer, increased with age faster for young males, and then declined for some older animals, as expected from disease-associated mortality and age-related changes in infection risk. We found that disease prevalence was clustered in a central location, as expected under a simple spatial epidemic process where disease prevalence should increase with time and expand spatially. However, we could not detect any consistent temporal or spatiotemporal trends in CWD prevalence. Estimates of the temporal trend indicated that prevalence may have decreased or increased with nearly equal posterior probability, and the model without temporal or spatiotemporal effects was nearly equivalent to models with these effects based on deviance information criteria. For maximum interpretability of the role of location as a disease risk factor, we used the technique of direct standardization for prevalence mapping, which we develop and describe. These mapping results allow disease management actions to be employed with reference to the estimated spatial distribution of the disease and to those host classes most at risk. Future wildlife epidemiology studies should employ hierarchical Bayesian methods to smooth estimated quantities across space and time, account for heterogeneities, and then report disease rates based on an appropriate standardization. ?? 2009 by the Ecological Society of America.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological

This paper describes the Southern California Earthquake Center/U.S. Geological Survey (SCEC/USGS) Dynamic Earthquake Rupture Code Verification Exercise, where codes that simulate spontaneous rupture dynamics in three dimensions are evaluated and the results produced by these codes are compared using Web-based tools. This is the first time that a broad and rigorous examination of numerous spontaneous rupture codes has been performed—a significant advance in this science. The automated process developed to attain this achievement provides for a future where testing of codes is easily accomplished.</p><p id=\"p-2\">Scientists who use computer simulations to understand earthquakes utilize a range of techniques. Most of these assume that earthquakes are caused by slip at depth on faults in the Earth, but hereafter the strategies vary. Among the methods used in earthquake mechanics studies are kinematic approaches and dynamic approaches.</p><p id=\"p-3\">The kinematic approach uses a computer code that prescribes the spatial and temporal evolution of slip on the causative fault (or faults). These types of simulations are very helpful, especially since they can be used in seismic data inversions to relate the ground motions recorded in the field to slip on the fault(s) at depth. However, these kinematic solutions generally provide no insight into the physics driving the fault slip or information about why the involved fault(s) slipped that much (or that little). In other words, these kinematic solutions may lack information about the physical dynamics of earthquake rupture that will be most helpful in forecasting future events.</p><p id=\"p-4\">To help address this issue, some researchers use computer codes to numerically simulate earthquakes and construct dynamic, spontaneous rupture (hereafter called “spontaneous rupture”) solutions. For these types of numerical simulations, rather than prescribing the slip function at each location on the fault(s), just the friction constitutive properties and initial stress conditions are prescribed. The subsequent stresses and fault slip spontaneously evolve over time as part of the elasto-dynamic solution. Therefore, spontaneous rupture computer simulations of earthquakes allow us to include everything that we know, or think that we know, about earthquake dynamics and to test these ideas against earthquake observations.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Seismological Research Letters","largerWorkSubtype":{"id":10,"text":"Journal

This column is an introduction to the types of information available from the U.S. Geological Survey (USGS), and explains how the data are assembled. The kind of information prepared by the USGS is essential to U.S. materials flow studies because the data make it possible to conduct these studies within a global context.

We used Global Positioning System location data from 24 individuals representing 18 sounders (i.e., F social groups) combined with markrecapture and camera-trap data to evaluate evidence of territorial behavior at the individual and sounder levels. Through a manipulative experiment, we examined evidence for an inverse relationship between population density and home range size that would be expected for territorial animals. Pigs from the same sounder had extensive home range overlap and did not have exclusive core areas. Sounders had nearly exclusive home ranges and had completely exclusive core areas, suggesting that female feral pigs on Fort Benning were territorial at the sounder level but not at the individual level. Lethal removal maintained stable densities of pigs in our treatment area, whereas density increased in our control area; territory size in the 2 areas was weakly and inversely related to density of pigs. Territorial behavior in feral pigs could influence population density by limiting access to reproductive space. Removal strategies that 1) match distribution of removal efforts to distribution of territories, 2) remove entire sounders instead of individuals, and 3) focus efforts where high-quality food resources strongly influence territorial behaviors may be best for long-term control of feral pigs.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/2007-585","issn":"0022541X","usgsCitation":"Sparklin, B., Mitchell, M., Hanson, L., Jolley, D., and Ditchkoff, S., 2009, Territoriality of feral pigs in a highly persecuted population on Fort Benning, Georgia: Journal of Wildlife Management, v. 73, no. 4, p. 497-502, https://doi.org/10.2193/2007-585.","startPage":"497","endPage":"502","numberOfPages":"6","costCenters":[],"links":[{"id":244262,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216395,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2007-585"}],"volume":"73","issue":"4","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"505ba569e4b08c986b320a24","contributors":{"authors":[{"text":"Sparklin, B.D.","contributorId":30047,"corporation":false,"usgs":true,"family":"Sparklin","given":"B.D.","email":"","affiliations":[],"preferred":false,"id":451453,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mitchell, M.S.","contributorId":26724,"corporation":false,"usgs":true,"family":"Mitchell","given":"M.S.","email":"","affiliations":[],"preferred":false,"id":451452,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hanson, L.B.","contributorId":36759,"corporation":false,"usgs":true,"family":"Hanson","given":"L.B.","email":"","affiliations":[],"preferred":false,"id":451454,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jolley, D.B.","contributorId":60862,"corporation":false,"usgs":true,"family":"Jolley","given":"D.B.","email":"","affiliations":[],"preferred":false,"id":451455,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ditchkoff, S.S.","contributorId":100580,"corporation":false,"usgs":true,"family":"Ditchkoff","given":"S.S.","affiliations":[],"preferred":false,"id":451456,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

We implemented a manipulative experiment of feral pig (Sus scrofa) populations at Fort Benning, Georgia, USA, to assess the demographic effects of harvest intensity. Using markrecapture data, we estimated annual survival, recruitment, and population growth rates of populations in a moderately harvested area and a heavily harvested area for 200406. Population growth rates did not differ between the populations. The top-ranked model for survival included a harvest intensity effect; model-averaged survival was lower for the heavily harvested population than for the moderately harvested population.

Hurricanes can dramatically affect a site's soil elevation. We assessed the impact of Hurricane Wilma (2005) on soil elevation at a mangrove forest location along the Shark River in Everglades National Park, Florida, USA. Using multiple depth surface elevation tables (SETs) and marker horizons we measured soil accretion, erosion, and soil elevation. We partitioned the effect of Hurricane Wilma's storm deposit into four constituent soil zones: surface (accretion) zone, shallow zone (0–0.35 m), middle zone (0.35–4 m), and deep zone (4–6 m). We report expansion and contraction of each soil zone. Hurricane Wilma deposited 37.0 (± 3.0 SE) mm of material; however, the absolute soil elevation change was + 42.8 mm due to expansion in the shallow soil zone. One year post-hurricane, the soil profile had lost 10.0 mm in soil elevation, with 8.5 mm of the loss due to erosion. The remaining soil elevation loss was due to compaction from shallow subsidence. We found prolific growth of new fine rootlets (209 ± 34 SE g m<sup>−2</sup>) in the storm deposited material suggesting that deposits may become more stable in the near future (i.e., erosion rate will decrease). Surficial erosion and belowground processes both played an important role in determining the overall soil elevation. Expansion and contraction in the shallow soil zone may be due to hydrology, and in the middle and bottom soil zones due to shallow subsidence. Findings thus far indicate that soil elevation has made substantial gains compared to site specific relative sea-level rise, but data trends suggest that belowground processes, which differ by soil zone, may come to dominate the long term ecological impact of storm deposit.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Society of Wetland Scientists","doi":"10.1672/08-125.1","issn":"02775212","usgsCitation":"Whelan, K., Smith, T.J., Anderson, G., and Ouellette, M., 2009, Hurricane Wilma's impact on overall soil elevation and zones within the soil profile in a mangrove forest: Wetlands, v. 29, no. 1, p. 16-23, https://doi.org/10.1672/08-125.1.","productDescription":"8 p.","startPage":"16","endPage":"23","costCenters":[{"id":275,"text":"Florida Integrated Science Center","active":false,"usgs":true}],"links":[{"id":215373,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1672/08-125.1"},{"id":243171,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Florida","otherGeospatial":"Everglades National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -81.52,24.85 ], [ -81.52,25.89 ], [ -80.39,25.89 ], [ -80.39,24.85 ], [ -81.52,24.85 ] ] ] } } ] }","volume":"29","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a32b4e4b0c8380cd5e9fb","contributors":{"authors":[{"text":"Whelan, K.R.T.","contributorId":11311,"corporation":false,"usgs":true,"family":"Whelan","given":"K.R.T.","email":"","affiliations":[],"preferred":false,"id":450276,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Smith, T.

In Georgia and northern Florida, the species is associated with longleaf pine habitats that support Gopherus polyphemus (Gopher Tortoise) populations, the burrows of which D. couperi uses for shelter. The extent that D. couperi uses these burrows, in addition to the use of other underground shelters and the microhabitat features associated with these structures is largely unknown. From 2003 through 2004, we conducted a radiotelemetry study of D. couperi (n = 32) to examine use of shelters and microhabitat in Georgia. We used repeated measures regression on a candidate set of models created from a priori hypotheses using principal component scores, derived from analysis of microhabitat data to examine microhabitat use at underground shelters. Proportion of locations recorded underground did not differ seasonally or between sexes. In winter, we recorded >0.90 of underground locations at tortoise burrows. Use of these burrows was less pronounced in spring for males. Females used abandoned tortoise burrows more frequently than males year-round and used them on approximately 0.60 of their underground locations during spring. Microhabitat use at underground shelters was most influenced by season compared to sex, site, or body size. Females in spring and summer used more open microhabitat compared to males, potentially in response to gestation. Our results suggest that the availability of suitable underground shelters, especially G. polyphemus burrows, may be a limiting factor in the northern range of D. couperi, with important implications for its conservation. ?? 2009 by the American Society of Ichthyologists and Herpetologists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Copeia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1643/CH-07-171","issn":"00458511","usgsCitation":"Hyslop, N., Cooper, R., and Meyers, J., 2009, Seasonal shifts in shelter and microhabitat use of drymarchon couperi (eastern indigo snake) in Georgia: Copeia, v. 2009, no. 3, p. 458-464, https://doi.org/10.1643/CH-07-171.","startPage":"458","endPage":"464","numberOfPages":"7","costCenters":[],"links":[{"id":243914,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216072,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1643/CH-07-171"}],"volume":"2009","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b88d7e4b08c986b316bcd","contributors":{"authors":[{"text":"Hyslop, N.L.","contributorId":22066,"corporation":false,"usgs":true,"family":"Hyslop","given":"N.L.","email":"","affiliations":[],"preferred":false,"id":451705,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cooper, R.J.","contributorId":89077,"corporation":false,"usgs":true,"family":"Cooper","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":451707,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Meyers, J.M.","contributorId":54307,"corporation":false,"usgs":true,"family":"Meyers","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":451706,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

For example, the influence of climatic &ldquo;teleconnections&rdquo; (the relationship between oceanic&ndash;atmospheric fluctuations and anomalous weather patterns across broad scales) on forest age structure is relatively unexplored. We sampled semiarid pi&ntilde;on&ndash;juniper (</span><i>Pinus edulis</i><span>&ndash;</span><i>Juniperus osteosperma</i><span>) woodlands in western Colorado, USA, to test the hypothesis that woodland age structures are shaped by climate, including links to oceanic&ndash;atmospheric fluctuations, and by past fires and livestock grazing. Low-severity surface fire was lacking, as fire scars were absent, and did not influence woodland densities, but stand-replacing fires served as long-rotation (&gt;400&ndash;600 years), stand-initiating events. Old-growth stands (&gt;300 years old) were found in 75% of plots, consistent with a long fire rotation. Juniper and pi&ntilde;on age structures suggest contrasting responses during the past several centuries to dry and wet episodes linked to the Atlantic Multidecadal Oscillation (AMO) and Pacific Decadal Oscillation (PDO). Juniper density increased slightly during periods of drought, positive (warm) AMO (after &sim;10-year lag), and negative (cool) PDO. In contrast, pi&ntilde;on populations may still be recovering from a long, drought-filled period (AD 1620&ndash;1820), with pulses of recovery favored during cool AMO, warm PDO, and above-average moisture periods. Analysis of 20th-century tree establishment and instrumental climate data corroborate the long-term relationships between age structure and climate. After Euro&ndash;American settlement (AD 1881), livestock grazing reduced understory grasses and forbs, reducing competition with tree seedlings and facilitating climate-induced increases in pi&ntilde;ons. Thus tree populations in these woodlands are in flux, affected by drought and wet periods linked to oceanic&ndash;atmospheric variability, Euro&ndash;American livestock grazing, and long-rotation, high-severity fires. Reductions in livestock grazing levels may aid ecological restoration efforts.

Trace-element signatures of zircons from the Caledonian UHP terrane in North-East Greenland were used to examine the possible changes in signature with age during exhumation. Collection and interpretation of age and trace-element analyses of zircon from three samples of quartzofeldspathic gneiss and two leucocratic intrusions were guided by core vs. rim zoning patterns as imaged by cathodoluminesence. Change from igneous to eclogite-facies metamorphic trace-element signature in protolith zircon is characterized by gradual depletion of HREE, whereas newly formed metamorphic rims have flat HREE patterns and REE concentrations that are distinct from the recrystallized inherited cores. The signature associated with eclogite-facies metamorphic zircon is observed in coesite-bearing zircon formed at 358 ?? 4 Ma, metamorphic rims formed at 348 ?? 5 Ma during the initial stages of exhumation, and metamorphic rims formed at 337 ?? 5 Ma. Zircons from a garnet-bearing granite emplaced in the neck of an eclogite boudin and a leucocratic dike that cross-cuts amphibolite-facies structural fabrics have steeply sloping HREE patterns, variably developed negative Eu anomalies, and low Th/U ratios. The granite records initial decompression melting and exhumation at 347 ?? 2 Ma and later zircon rim growth at 329 ?? 5. The leucocratic dike was likely emplaced at amphibolite-facies conditions at 330 ?? 2 Ma, but records additional growth of compositionally similar zircon at 321 ??2 Ma. The difference between the trace-element signature of metamorphic zircon in the gneisses and in part coeval leucocratic intrusions indicates that the zircon signature varies as a function of lithology and context, thus enhancing its ability to aid in the interpretation of U-Pb data and track the exhumation history of UHP terranes. The differences may reflect variation in elemental availability through breakdown reactions in quartzofeldpathic gneiss vs. availability during melt production and/or crystallization. UHP rocks in North-East Greenland began exhumation by 347 ?? 2 Ma, were still at HP eclogite-facies conditions at 337 ?? 5 Ma and were at amphibolite-facies conditions by 330 ?? 2 Ma. ?? 2009 E.

These events have reduced stress on the western segment of the NAF where it continues under the Marmara Sea. The undersea fault segments have been recently explored using bathymetric and reflection surveys. These recent findings helped scientists to understand the seismotectonic environment of the Marmara basin, which has remained a perplexing tectonic domain. On the basis of collected new data, seismic hazard of the Marmara region is reassessed using a probabilistic approach. Two different earthquake source models: (1) the smoothed-gridded seismicity model and (2) fault model and alternate magnitude-frequency relations, Gutenberg-Richter and characteristic, were used with local and imported ground-motion-prediction equations. Regional exposure is computed and quantified on a set of hazard maps that provide peak horizontal ground acceleration (PGA) and spectral acceleration at 0.2 and 1.0 sec on uniform firm-rock site condition (760 m=sec average shear wave velocity in the upper 30 m). These acceleration levels were computed for ground motions having 2% and 10% probabilities of exceedance in 50 yr, corresponding to return periods of about 2475 and 475 yr, respectively. The maximum PGA computed (at rock site) is 1.5g along the fault segments of the NAF zone extending into the Marmara Sea. The new maps generally show 10% to 15% increase for PGA, 0.2 and 1.0 sec spectral acceleration values across much of Marmara compared to previous regional hazard maps. Hazard curves and smooth design spectra for three site conditions: rock, soil, and soft-soil are provided for the Istanbul metropolitan area as possible tools in future risk estimates.","language":"English","publisher":"Seismological Society of America","doi":"10.1785/0120080285","issn":"00371106","usgsCitation":"Kalkan, E., Gulkan, P., Yilmaz, N., and Çelebi, M., 2009, Reassessment of probabilistic seismic hazard in the Marmara region: Bulletin of the Seismological Society of America, v. 99, no. 4, p. 2127-2146, https://doi.org/10.1785/0120080285.","productDescription":"20 p.","startPage":"2127","endPage":"2146","numberOfPages":"20","ipdsId":"IP-012613","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":245408,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217458,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120080285"}],"volume":"99","issue":"4","noUsgsAuthors":false,"publicationDate":"2009-07-29","publicationStatus":"PW","scienceBaseUri":"505a95c0e4b0c8380cd81bf4","contributors":{"authors":[{"text":"Kalkan, Erol 0000-0002-9138-9407 ekalkan@usgs.gov","orcid":"https://orcid.org/0000-0002-9138-9407","contributorId":1218,"corporation":false,"usgs":true,"family":"Kalkan","given":"Erol","email":"ekalkan@usgs.gov","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":458113,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gulkan, Polat","contributorId":78532,"corporation":false,"usgs":true,"family":"Gulkan","given":"Polat","email":"","affiliations":[],"preferred":false,"id":458116,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Yilmaz, Nazan","contributorId":198749,"corporation":false,"usgs":false,"family":"Yilmaz","given":"Nazan","email":"","affiliations":[],"preferred":false,"id":458115,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Çelebi, Mehmet 0000-0002-4769-7357 celebi@usgs.gov","orcid":"https://orcid.org/0000-0002-4769-7357","contributorId":3205,"corporation":false,"usgs":true,"family":"Çelebi","given":"Mehmet","email":"celebi@usgs.gov","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":false,"id":458114,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The broadband synthetics were constructed for earthquakes of M 5.5, 6.5, and 7.5 by combining deterministic synthetics for plane-layered models at low frequencies with stochastic synthetics at high frequencies. The stochastic portion used a source model where the Brune stress drop of 100 bars is constant with seismic moment. The deterministic synthetics were calculated using an average slip velocity, and hence, dynamic stress drop, on the fault that is uniform with magnitude. One novel aspect of this procedure is that the transition frequency between the deterministic and stochastic portions varied with magnitude, so that the transition frequency is inversely related to the rise time of slip on the fault. The spectral accelerations at 0.2, 1.0, and 3.0 sec periods from the synthetics generally agreed with those from the set of NGA relations for M 5.5-7.5 for distances of 2-100 km. At distances of 100-200 km some of the NGA relations for 0.2 sec spectral acceleration were substantially larger than the values of the synthetics for M 7.5 and M 6.5 earthquakes because these relations do not have a term accounting for Q. At 3 and 5 sec periods, the synthetics for M 7.5 earthquakes generally had larger spectral accelerations than the NGA relations, although there was large scatter in the results from the synthetics. The synthetics showed a sag in response spectra at close-in distances for M 5.5 between 0.3 and 0.7 sec that is not predicted from the NGA relations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120080079","issn":"00371106","usgsCitation":"Frankel, A., 2009, A constant stress-drop model for producing broadband synthetic seismograms: Comparison with the next generation attenuation relations: Bulletin of the Seismological Society of America, v. 99, no. 2 A, p. 664-680, https://doi.org/10.1785/0120080079.","startPage":"664","endPage":"680","numberOfPages":"17","costCenters":[],"links":[{"id":217459,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120080079"},{"id":245409,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"99","issue":"2 A","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e396e4b0c8380cd46100","contributors":{"authors":[{"text":"Frankel, A. 0000-0001-9119-6106","orcid":"https://orcid.org/0000-0001-9119-6106","contributorId":41593,"corporation":false,"usgs":true,"family":"Frankel","given":"A.","affiliations":[],"preferred":false,"id":458117,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Aerial surveys often can provide these data; however, associated costs necessitate designing and conducting surveys efficiently. We developed methods to simulate population distributions of mallards (Anas platyrhynchos) wintering in western Mississippi, USA, by combining bird observations from three previous strip-transect surveys and habitat data from three sets of satellite images representing conditions when surveys were conducted. For each simulated population distribution, we compared 12 primary survey designs and two secondary design options by using coefficients of variation (CV) of population indices as the primary criterion for assessing survey performance. In all, 3 of the 12 primary designs provided the best precision (CV???11.7%) and performed equally well (WR08082E1d.gif <sub>diff</sub>???0.6%). Features of the designs that provided the largest gains in precision were optimal allocation of sample effort among strata and configuring the study area into five rather than four strata, to more precisely estimate mallard indices in areas of consistently high density. Of the two secondary design options, we found including a second observer to double the size of strip transects increased precision or decreased costs, whereas ratio estimation using auxiliary habitat data from satellite images did not increase precision appreciably. We recommend future surveys of mallard populations in our study area use the strata we developed, optimally allocate samples among strata, employ PPS or EPS sampling, and include two observers when qualified staff are available. More generally, the methods we developed to simulate population distributions from prior survey data provide a cost-effective method to assess performance of alternative wildlife surveys critical to informing management decisions, and could be extended to account for effects of detectability on estimates of true abundance. ?? 2009 CSIRO.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wildlife Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1071/WR08082","issn":"10353712","usgsCitation":"Pearse, A., Reinecke, K.J., Dinsmore, S., and Kaminski, R., 2009, Using simulation to improve wildlife surveys: Wintering mallards in Mississippi, USA: Wildlife Research, v. 36, no. 4, p. 279-288, https://doi.org/10.1071/WR08082.","startPage":"279","endPage":"288","numberOfPages":"10","costCenters":[],"links":[{"id":217486,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1071/WR08082"},{"id":245437,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"36","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc0a1e4b08c986b32a22f","contributors":{"authors":[{"text":"Pearse, A.T.","contributorId":56333,"corporation":false,"usgs":true,"family":"Pearse","given":"A.T.","email":"","affiliations":[],"preferred":false,"id":458120,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reinecke, K.

We used cross-validation and an independent telemetry data set to test the habitat model. We also conducted a least-cost path analysis to identify potential habitat linkages and to provide a relative measure of connectivity among habitat patches. Variables in our model were paved road density, major highways, human population density, percentage of the area permanently or semipermanently flooded, and percentage of the area in natural land cover. Our model clearly identified habitat typical of that found within panther home ranges based on model testing with recent telemetry data. We identified 4 potential translocation sites that may support a total of approximately 36 panthers. Although we identified potential habitat linkages, our least-cost path analyses highlighted the extreme isolation of panther habitat in portions of the study area.

Over the past decade, studies have shown that these areas (commonly called \"cold spots\") are usually due to emissivity effects of frost deposits and occasionally to active C02 snowstorms. Three Mars years of Mars Global Surveyor Thermal Emission Spectrometer data were used to observe autumn and wintertime cold spot activity within the polar regions. Many cold spots formed on or near scarps of the perennial cap, probably induced by adiabatic cooling due to orographic lifting. These topographically associated cold spots were often smaller than those that were not associated with topography. We determined that initial grain sizes within the cold spots were on the order of a few millimeters, assuming the snow was uncontaminated by dust or water ice. On average, the half-life of the cold spots was 5 Julian days. The Mars global dust storm in 2001 significantly affected cold spot activity in the north polar region. Though overall perennial cap cold spot activity seemed unaffected, the distribution of cold spots did change by a decrease in the number of topographically associated cold spots and an increase in those not associated with topography. We propose that the global dust storm affected the processes that form cold spots and discuss how the global dust storm may have affected these processes. ?? 2009 by the American Geophysical Union.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research E: Planets","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1029/2008JE003243","issn":"01480227","usgsCitation":"Cornwall, C., and Titus, T., 2009, Spatial and temporal distributions of Martian north polar cold spots before, during, and after the global dust storm of 2001: Journal of Geophysical Research E: Planets, v. 114, no. 2, https://doi.org/10.1029/2008JE003243.","costCenters":[],"links":[{"id":243915,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216073,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2008JE003243"}],"volume":"114","issue":"2","noUsgsAuthors":false,"publicationDate":"2009-02-12","publicationStatus":"PW","scienceBaseUri":"505b9437e4b08c986b31a935","contributors":{"authors":[{"text":"Cornwall, C.","contributorId":43592,"corporation":false,"usgs":true,"family":"Cornwall","given":"C.","email":"","affiliations":[],"preferred":false,"id":451906,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Titus, T.N.","contributorId":102615,"corporation":false,"usgs":true,"family":"Titus","given":"T.N.","email":"","affiliations":[],"preferred":false,"id":451907,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This investigation is a continuation of work started by Kirk et al. (2005), who empirically deconvolved Thermal Emission Imaging System (THEMIS) visible and thermal infrared data of this area, isolating topographic information that produced an accurate DTM. Surface temperatures change as a function of many variables such as slope, albedo, thermal inertia, time, season, and atmospheric opacity. We constrain each of these variables to construct a DTM and maps of slope-corrected albedo, slope- and albedo-corrected thermal inertia, and surface temperatures across the scene for any time of day or year and at any atmospheric opacity. DTMs greatly facilitate analyses of the Martian surface, and the MOLA global data set is not finely scaled enough (128 pixels per degree, ???0.5 km per pixel near the equator) to be combined with newer data sets (e.g., High Resolution Imaging Science Experiment, Context Camera, and Compact Reconnaissance Imaging Spectrometer for Mars at ???0.25, ???6, and ???20 m per pixel, respectively), so new techniques to derive high-resolution DTMs are always being explored. This paper discusses our technique of combining a set of THEMIS visible and thermal infrared observations such that albedo and thermal inertia variations within the scene are eliminated and only topographic variations remain. This enables us to produce a high-resolution DTM via photoclinometry techniques that are largely free of albedo-induced errors. With this DTM, THEMIS observations, and a subsurface thermal diffusion model, we generate slope-corrected maps of albedo, thermal inertia, and surface temperatures. In addition to greater accuracy, these products allow thermophysical properties to be directly compared with topography.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research E: Planets","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1029/2008JE003292","issn":"01480227","usgsCitation":"Cushing, G., Titus, T., Soderblom, L., and Kirk, R.L., 2009, THEMIS high-resolution digital terrain: Topographic and thermophysical mapping of Gusev Crater, Mars: Journal of Geophysical Research E: Planets, v. 114, no. 7, https://doi.org/10.1029/2008JE003292.","costCenters":[],"links":[{"id":217687,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2008JE003292"},{"id":245647,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"114","issue":"7","noUsgsAuthors":false,"publicationDate":"2009-07-15","publicationStatus":"PW","scienceBaseUri":"505ba383e4b08c986b31fd2c","contributors":{"authors":[{"text":"Cushing, G.E.","contributorId":56778,"corporation":false,"usgs":true,"family":"Cushing","given":"G.E.","email":"","affiliations":[],"preferred":false,"id":458177,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Titus, T.N.","contributorId":102615,"corporation":false,"usgs":true,"family":"Titus","given":"T.N.","email":"","affiliations":[],"preferred":false,"id":458179,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Soderblom, L.A. 0000-0002-0917-853X","orcid":"https://orcid.org/0000-0002-0917-853X","contributorId":6139,"corporation":false,"usgs":true,"family":"Soderblom","given":"L.A.","affiliations":[],"preferred":false,"id":458176,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kirk, R.

Monitoring forest changes arising from such disturbances and the post-disturbance recovery processes is essential for assessing the conditions of the NFs and the effectiveness of management approaches. In this study, we used time series stacks of Landsat images (LTSS) to evaluate the dynamics of seven NFs in eastern United States, including the De Soto NF, the Talladega NF, the Francis Marion NF, and the Uwharrie NF in southeastern U.S., and the Chequamegon NF, the Hiawatha NF, and the Superior NF in northern U.S. Each LTSS consisted of 12–14 Landsat images acquired for the same location, spanning from 1984 to 2006 with a nominal interval of one image every 2&nbsp;years. Each LTSS was analyzed using a vegetation change tracker (VCT) algorithm to map forest disturbance. Accuracy assessments of the derived disturbance maps revealed that they had overall accuracy values of about 80%, with most of the disturbance classes having user's accuracies ranging from 70% to 95%. The producer's accuracies were generally lower, with the majority being in the range between 50% and 70%. While this may suggest that the disturbance maps could slightly underestimate disturbances, a more detailed assessment of the omission errors revealed that the majority of the disagreements were due to minor disturbances like thinning or storm damages that were identified by the image analysts but were not captured by the VCT algorithm.</p><p id=\"\">The derived disturbance year maps revealed that while each of the seven NFs consisted of 90% or more forest land, significant portions of the forests were disturbed since 1984. Mapped disturbances accounted for about 30%–45% of total land area in the four NFs in southeastern U.S. and about 10%–20% in the three NFs in northern U.S. The disturbance rates were generally higher in the buffer zones surrounding each NF, and varied considerably over time. The time series approach employed in this study represents a new approach for monitoring forest resources using the Landsat or similar satellite data records. The disturbance products derived using this approach were spatially explicit and contained much more temporal details than conventional bi-temporal change products, and likely will be found more useful by many users including ecologists and resources managers. The high disturbance rates found in the southeastern U.S. suggest that this region may have a more significant role in modulating the atmospheric carbon budget than currently recognized.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.rse.2008.06.016","issn":"00344257","usgsCitation":"Huang, C., Goward, S., Schleeweis, K., Thomas, N., Masek, J.G., and Zhu, Z., 2009, Dynamics of national forests assessed using the Landsat record: Case studies in eastern United States: Remote Sensing of Environment, v. 113, no. 7, p. 1430-1442, https://doi.org/10.1016/j.rse.2008.06.016.","productDescription":"13 p.","startPage":"1430","endPage":"1442","numberOfPages":"13","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":245679,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217718,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.rse.2008.06.016"}],"volume":"113","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0434e4b0c8380cd50855","contributors":{"authors":[{"text":"Huang, C.","contributorId":65255,"corporation":false,"usgs":true,"family":"Huang","given":"C.","email":"","affiliations":[],"preferred":false,"id":458182,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Goward, S.N.","contributorId":94514,"corporation":false,"usgs":true,"family":"Goward","given":"S.N.","affiliations":[],"preferred":false,"id":458184,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schleeweis, K.","contributorId":10258,"corporation":false,"usgs":true,"family":"Schleeweis","given":"K.","affiliations":[],"preferred":false,"id":458180,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Thomas, N.","contributorId":72490,"corporation":false,"usgs":true,"family":"Thomas","given":"N.","email":"","affiliations":[],"preferred":false,"id":458183,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Masek, J.

We estimated levels of population subdivision within Pacific Common Eiders (<i>Somateria mollissima v-nigrum</i>) breeding on 12 barrier islands in the western Beaufort Sea, Alaska, using molecular markers and capture—mark—recapture (CMR) data. Common Eider populations were genetically structured on a microgeographic scale. Regional comparisons between populations breeding on island groups separated by 90 km (Mikkelsen Bay and Simpson Lagoon) revealed structuring at 14 microsatellite loci (<i>F</i> <sub>ST</sub> = 0.004, <i>P</i> &lt; 0.01), a nuclear intron (<i>F</i> <sub>ST</sub> = 0.022, <i>P</i> = 0.02), and mitochondrial DNA (Φ<sub>ST</sub> = 0.082, <i>P</i> &lt; 0.05). The CMR data (<i>n</i> = 34) did not indicate female dispersal between island groups. Concordance between genetic and CMR data indicates that females breeding in the western Beaufort Sea are strongly philopatric to island groups rather than to a particular island. Despite the apparent high site fidelity of females, coalescence-based models of gene flow suggest that asymmetrical western dispersal occurs between island groups and is likely mediated by Mikkelsen Bay females stopping early on spring migration at Simpson Lagoon to breed. Alternatively, late-arriving females may be predisposed to nest in Simpson Lagoon because of the greater availability and wider distribution of nesting habitat. Our results indicate that genetic discontinuities, mediated by female philopatry, can exist at microgeographic scales along established migratory corridors.</p></div></div>","language":"English","publisher":"American Ornithological Society","doi":"10.1525/auk.2009.08224","issn":"00048038","usgsCitation":"Sonsthagen, S.A., Talbot, S.L., Lanctot, R., Scribner, K.T., and McCracken, K.G., 2009, Hierarchical spatial genetic structure of Common Eiders (<i>Somateria mollissima</i>) breeding along a migratory corridor: The Auk, v. 126, no. 4, p. 744-754, https://doi.org/10.1525/auk.2009.08224.","productDescription":"11 p.","startPage":"744","endPage":"754","costCenters":[],"links":[{"id":476167,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1525/auk.2009.08224","text":"Publisher Index Page"},{"id":242971,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"126","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a30a3e4b0c8380cd5d7f8","contributors":{"authors":[{"text":"Sonsthagen, Sarah A. 0000-0001-6215-5874 ssonsthagen@usgs.gov","orcid":"https://orcid.org/0000-0001-6215-5874","contributorId":3711,"corporation":false,"usgs":true,"family":"Sonsthagen","given":"Sarah","email":"ssonsthagen@usgs.gov","middleInitial":"A.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":449948,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Talbot, Sandra L. 0000-0002-3312-7214 stalbot@usgs.gov","orcid":"https://orcid.org/0000-0002-3312-7214","contributorId":140512,"corporation":false,"usgs":true,"family":"Talbot","given":"Sandra","email":"stalbot@usgs.gov","middleInitial":"L.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":449947,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lanctot, Richard B.","contributorId":77879,"corporation":false,"usgs":false,"family":"Lanctot","given":"Richard B.","affiliations":[{"id":6987,"text":"U.S. Fish and Wildlife Sevice","active":true,"usgs":false}],"preferred":false,"id":449949,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Scribner, Kim T.","contributorId":146113,"corporation":false,"usgs":false,"family":"Scribner","given":"Kim","email":"","middleInitial":"T.","affiliations":[{"id":16582,"text":"Department of Fisheries and Wildlife and Department of Zoology, 480 Wilson Rd. 13 Natural Resources Building, Michigan State University, East Lansing, MI 48824","active":true,"usgs":false},{"id":135,"text":"Biological Resources Division","active":false,"usgs":true}],"preferred":false,"id":449950,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"McCracken, Kevin G.","contributorId":72309,"corporation":false,"usgs":false,"family":"McCracken","given":"Kevin","email":"","middleInitial":"G.","affiliations":[{"id":6752,"text":"University of Alaska Fairbanks","active":true,"usgs":false}],"preferred":false,"id":449946,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

We estimated effects of chemical immobilization on mortality rates of African buffalo (Syncerus caffer) in the Kruger National Park, South Africa. We used a Cox proportional hazards approach to test for differences in mortality among age, sex, and capture classes of repeatedly captured radiocollared buffalo. Capture variables did not improve model fit and the Cox regression did not indicate increased risk of death for captured individuals up to 90 days postcapture [exp (??) = 1.07]. Estimated confidence intervals, however, span from a halving to a doubling of the mortality rate (95% CI = 0.56-2.02). Therefore, capture did not influence survival of captured individuals using data on 875 captures over a 5-year period. Consequently, long-term research projects on African buffalo involving immobilization, such as associated with research on bovine tuberculosis, should result in minimal capture mortality, but monitoring of possible effects should continue.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/2008-071","issn":"00225","usgsCitation":"Oosthuizen, W., Cross, P., Bowers, J., Hay, C., Ebinger, M., Buss, P., Hofmeyr, M., and Cameron, E., 2009, Effects of chemical immobilization on survival of African buffalo in the Kruger National Park: Journal of Wildlife Management, v. 73, no. 1, p. 149-153, https://doi.org/10.2193/2008-071.","startPage":"149","endPage":"153","numberOfPages":"5","costCenters":[],"links":[{"id":502638,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://figshare.com/articles/journal_contribution/Effects_of_chemical_immobilization_on_survival_of_African_Buffalo_in_the_Kruger_National_Park/22879940","text":"External Repository"},{"id":213486,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2008-071"},{"id":241113,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"73","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"505a06a8e4b0c8380cd51363","contributors":{"authors":[{"text":"Oosthuizen, W.C.","contributorId":80494,"corporation":false,"usgs":true,"family":"Oosthuizen","given":"W.C.","email":"","affiliations":[],"preferred":false,"id":438949,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cross, P.C.","contributorId":48141,"corporation":false,"usgs":true,"family":"Cross","given":"P.C.","email":"","affiliations":[],"preferred":false,"id":438947,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bowers, J.A.","contributorId":30456,"corporation":false,"usgs":true,"family":"Bowers","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":438946,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hay, C.","contributorId":25369,"corporation":false,"usgs":true,"family":"Hay","given":"C.","email":"","affiliations":[],"preferred":false,"id":438945,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ebinger, M.R.","contributorId":51100,"corporation":false,"usgs":true,"family":"Ebinger","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":438948,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Buss, P.","contributorId":97705,"corporation":false,"usgs":true,"family":"Buss","given":"P.","email":"","affiliations":[],"preferred":false,"id":438950,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Hofmeyr, M.","contributorId":6662,"corporation":false,"usgs":true,"family":"Hofmeyr","given":"M.","email":"","affiliations":[],"preferred":false,"id":438943,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Cameron, E.Z.","contributorId":13045,"corporation":false,"usgs":true,"family":"Cameron","given":"E.Z.","email":"","affiliations":[],"preferred":false,"id":438944,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}
