Wiederholt Ruscena, Laura López-Hoffman, Jon Cline, Rodrigo Medellin, Paul M. Cryan, Amy Russell, Gary McCracken, Jay Diffendorfer, Darius J. Semmens
2013, Ecosphere (4)
The migration of animals across long distances and between multiple habitats presents a major challenge for conservation. For the migratory Mexican free-tailed bat (Tadarida brasiliensis mexicana), these challenges include identifying and protecting migratory routes and critical roosts in two countries, the United States and Mexico. Knowledge and conservation of bat...
Emergency assessment of post-fire debris-flow hazards for the 2013 Rim Fire, Stanislaus National Forest and Yosemite National Park, California
Dennis M. Staley
2013, Open-File Report 2013-1260
Wildfire can significantly alter the hydrologic response of a watershed to the extent that even modest rainstorms can produce dangerous flash floods and debris flows. In this report, empirical models are used to predict the probability and magnitude of debris-flow occurrence in response to a 10-year rainstorm for the 2013...
Nitrate in the Mississippi River and its tributaries, 1980-2010: an update
Jennifer C. Murphy, Robert M. Hirsch, Lori A. Sprague
2013, Scientific Investigations Report 2013-5169
Nitrate concentration and flux were estimated from 1980 through 2010 at eight sites in the Mississippi River Basin as part of the National Water-Quality Assessment (NAWQA) Program of the U.S. Geological Survey (USGS). These estimates extend the results from a previous investigation that provided nitrate estimates from 1980 through 2008...
Injection-induced earthquakes
William L. Ellsworth
2013, Science (341) 142-143
Earthquakes in unusual locations have become an important topic of discussion in both North America and Europe, owing to the concern that industrial activity could cause damaging earthquakes. It has long been understood that earthquakes can be induced by impoundment of reservoirs, surface and underground mining, withdrawal of fluids and...
Tumors in sea turtles: The insidious menace of fibropapillomatosis
Thierry M. Work, George H. Balazs
2013, The Wildlife Professional (Fall 2013) 44-47
Early in July 2013, a colleague in New Caledonia reported the stranding of a green sea turtle on the far northwest of the island. The animal had washed up dead on a rocky beach with multiple large tumors on its neck and hind flippers. To all appearances, the turtle had...
Crustal structure and fault geometry of the 2010 Haiti earthquake from temporary seismometer deployments
Roby Douilly, Jennifer S. Haase, William L. Ellsworth, Marie-Paule Bouin, Eric Calais, Steeve J. Symithe, John G. Armbruster, Bernard Mercier de Lepinay, Anne Deschamps, Saint‐Louis Mildor, Mark E. Meremonte, Susan E. Hough
2013, Bulletin of the Seismological Society of America (103) 2305-2325
Haiti has been the locus of a number of large and damaging historical earthquakes. The recent 12 January 2010 Mw 7.0 earthquake affected cities that were largely unprepared, which resulted in tremendous losses. It was initially assumed that the earthquake ruptured the Enriquillo Plantain Garden fault (EPGF), a major active...

2013, Scientific Investigations Report 2013-5151
The influence of groundwater on surface-water quality in the San Joaquin River, California, was examined for a 59-mile reach from the confluence with Salt Slough to Vernalis. The primary objective of this study was to quantify the rate of groundwater discharged to the lower San Joaquin River and the contribution...
Monitoring change in Great Salt Lake
David L. Naftz, Cory E. Angeroth, Michael L. Freeman, Ryan C. Rowland, Gregory Carling
2013, Eos, Transactions, American Geophysical Union (94) 289-296
Despite the ecological and economic importance of Great Salt Lake, only limited water quality monitoring has occurred historically. To change this, new monitoring stations and networks—gauges of lake level height and rate of inflow, moored buoys, and multiple lake-bottom sensors—will provide important information that can be used to make informed...
Migration and wintering areas of American Bitterns (Botaurus lentiginosus) that summer in central North America as determined by satellite and radio telemetry, 1998-2003
Guy Huschle, John E. Toepfer, David C. Douglas
2013, Waterbirds (36) 300-309
Twenty adult male American Bitterns (Botaurus lentiginosus) were marked on summer range in central North America with satellite tracking Platform Transmitter Terminals (PTTs) to document migration routes and wintering range. Nineteen complete fall migration routes were documented for 17 individuals. Of the successful migrations, 63% (n = 12) went to...

Behaviors of southwestern native fishes in response to introduced catfish predators
David L. Ward, Chester R. Figiel Jr.
2013, Journal of Fish and Wildlife Management (4) 307-315
Native fishes reared in hatcheries typically suffer high predation mortality when stocked into natural environments. We evaluated the behavior of juvenile bonytail Gila elegans, roundtail chub Gila robusta, razorback sucker Xyrauchen texanus, and Sonora sucker Catostomus insignis in response to introduced channel catfish Ictalurus punctatus and flathead catfish Pylodictis olivaris....

Linking movement and reproductive history of brook trout to assess habitat connectivity in a heterogeneous stream network
Yoichiro Kanno, Benjamin H. Letcher, Jason A. Coombs, Keith H. Nislow, Andrew R. Whiteley
2013, Freshwater Biology (59) 142-154
1. Defining functional connectivity between habitats in spatially heterogeneous landscapes is a particular challenge for small-bodied aquatic species. Traditional approaches (e.g. mark–recapture studies) preclude an assessment of animal movement over the life cycle (birth to reproduction), and movement of individuals may not represent the degree of gene movement for fecund...

The effects of elevated water temperature on native juvenile mussels: implications for climate change
Alissa M. Ganser, Teresa J. Newton, Roger J. Haro
2013, Freshwater Science (32) 1168-1177
Native freshwater mussels are a diverse but imperiled fauna and may be especially sensitive to increasing water temperatures because many species already may be living near their upper thermal limits. We tested the hypothesis that elevated water temperatures (20, 25, 30, and 35°C) adversely affected the survival and physiology of...
Genetic structure, diversity and subspecies status of Gull-billed Terns (Gelochelidon nilotica) from the United States
Mark P. Miller, Thomas D. Mullins, Susan M. Haig
2013, Waterbirds (36) 310-318
Gull-billed Terns (Gelochelidon nilotica) are among the most widespread, yet scarce, Charadriiformes in the world. Two subspecies are recognized in the United States: G. n. aranea breeds along the U.S. Atlantic and Gulf coasts and G. n. vanrossemi breeds in the Salton Sea and San Diego Bay of California. Conservation...
Has the time come for big science in wildlife health?
Jonathan M. Sleeman
2013, EcoHealth (10) 335-338
The consequences of wildlife emerging diseases are global and profound with increased burden on the public health system, negative impacts on the global economy, declines and extinctions of wildlife species, and subsequent loss of ecological integrity. Examples of health threats to wildlife include Batrachochytrium dendrobatidis, which causes a cutaneous fungal...

2013, Data Series 801
In 2007, the U.S. Geological Survey initiated a low-density (1 site per 1,600 square kilometers, 4,857 sites) geochemical and mineralogical survey of soils of the conterminous United States as part of the North American Soil Geochemical Landscapes Project. Sampling and analytical protocols were developed at a workshop in 2003, and...
US Topo: topographic maps for the nation
William J. Carswell Jr.
2013, Fact Sheet 2013-3093
US Topo is the next generation of topographic maps from the U.S. Geological Survey (USGS). Arranged in the familiar 7.5-minute quadrangle format, digital US Topo maps are designed to look and feel (and perform) like the traditional paper topographic maps for which the USGS is so well known. In contrast...
