Relating large-scale climate variability to local species abundance: ENSO forcing and shrimp in Breton Sound, Louisiana, USA
Bryan P. Piazza, Megan K. LaPeyre, B.D. Keim
2010, Climate Research (42) 195-207
Climate creates environmental constraints (filters) that affect the abundance and distribution of species. In estuaries, these constraints often result from variability in water flow properties and environmental conditions (i.e. water flow, salinity, water temperature) and can have significant effects on the abundance and distribution of commercially important nekton species. We...
A methodology for the assessment of unconventional (continuous) resources with an application to the Greater Natural Buttes gas field, Utah
Ricardo A. Olea, Troy A. Cook, James L. Coleman
2010, Natural Resources Research (19) 237-251
The Greater Natural Buttes tight natural gas field is an unconventional (continuous) accumulation in the Uinta Basin, Utah, that began production in the early 1950s from the Upper Cretaceous Mesaverde Group. Three years later, production was extended to the Eocene Wasatch Formation. With the exclusion of 1100 non-productive (“dry”) wells,...

2010, Book chapter, Ecological assessment of selenium in the aquatic environment
This book on Ecological Assessment of Selenium in the Aquatic Environment synthesizes and advances the state-of-the-science regarding this unique metalloid and identies critical knowledge gaps. Assessment methods appropriate for other metals and metalloids are not always appropriate for selenium (Se). Selenium requires site-specific risk assessments to a much greater extent...
Effects of current-use pesticides on amphibians

Donald Sparling, Greg L. Linder, Christine A. Bishop, Sherry K. Krest, editor(s)
2010, Book chapter, Ecotoxicology of amphibians and reptiles
For many years, amphibians were understudied in the ecotoxicological literature. In 1989, the Canadian Wildlife Service published a comprehensive review of studies examining the effects of contaminants on amphibians (Power et al. 1989). Just 10 years later, the same organization published an updated review that included twice the number of...
Occupancy and habitat use of the Least Bittern and Pied-Billed Grebe in the Illinois and Upper Mississippi River Valleys
Abigail J. Darrah, David G. Krementz
2010, Waterbirds (33) 367-375
The Least Bittern (Ixobrychus exilis) and the Pied-billed Grebe (Podilymbus podiceps) are secretive marsh bird species that breed in the Illinois and Upper Mississippi River Valleys. Marsh bird surveys were conducted on public and private wetlands in this region during the breeding seasons of 2006 and 2007. Detection probability (ῥ)...
Bioenergetics assessment of fish and crayfish consumption by river otter (Lontra canadensis): integrating prey availability, diet, and field metabolic rate
Matthew P. Dekar, Daniel D. Magoulick, J. Beringer
2010, Canadian Journal of Fisheries and Aquatic Sciences (67) 1439-1448
River otters (Lontra canadensis) are important predators in aquatic ecosystems, but few studies quantify their prey consumption. We trapped crayfish monthly as an index of availability and collected otter scat for diet analysis in the Ozark Mountains of northwestern Arkansas, USA. We measured otter daily energy expenditure (DEE) with the...
Pathology and virus detection in tissues of nestling house sparrows naturally infected with Buggy Creek virus (Togaviridae).
Valerie A. O’Brien, Carol U. Meteyer, S. Ip, Renee Romaine Long, Charles R. Brown
2010, Journal of Wildlife Diseases (46) 23-32
Alphaviruses (Togaviridae) infect wild birds, but clinical illness and death attributable to virus in naturally infected birds is rarely reported, particularly for small passerine species or nestlings. Buggy Creek virus is a unique alphavirus in the Western equine encephalomyelitis virus (WEEV) complex that is vectored by the cimicid swallow bug (Oeciacus vicarius), an ectoparasite...

Effect of numerical dispersion as a source of structural noise in the calibration of a highly parameterized saltwater intrusion model
Christian D. Langevin, Joseph D. Hughes
2010, Book, Proceedings 2009 PEST Conference
A model with a small amount of numerical dispersion was used to represent saltwater 7 intrusion in a homogeneous aquifer for a 10-year historical calibration period with one 8 groundwater withdrawal location followed by a 10-year prediction period with two groundwater 9 withdrawal locations. Time-varying groundwater concentrations at arbitrary locations...

2010, Book chapter, Isoscapes
Isotopes are a potentially powerful component of monitoring and assessment programs aimed at quantifying and mitigating alterations to environments from human activities. In particular, isotopic techniques have proved useful for tracing sources and sinks of various pollutants in large river basins, wetlands, and airsheds. Many of these studies have been...

Beak deformities in Northwestern Crows: Evidence of a multispecies epizootic
Caroline R. Van Hemert, Colleen M. Handel
2010, The Auk (127) 746-751
Beak abnormalities are rare among adult birds and, typically, are not widespread in a given population, within a region, or across multiple species. A high concentration of beak deformities was recently documented in Black-capped Chickadees (Poecile atricapillus) and other resident avian species in Alaska. We describe a parallel condition in...
Iceberg calving during transition from grounded to floating ice: Columbia Glacier, Alaska
Fabian Walter, Shad O’Neel, Daniel McNamara, W.T. Pfeffer, Jeremy N. Bassis, Helen Amanda Fricker
2010, Geophysical Research Letters (37)
The terminus of Columbia Glacier, Alaska, unexpectedly became ungrounded in 2007 during its prolonged retreat. Visual observations showed that calving changed from a steady release of low-volume bergs, to episodic flow-perpendicular rifting, propagation, and release of very large icebergs - a style reminiscent of calving from ice shelves. Here, we...

2010, Report
This 18-month field study addresses the seasonal and spatial patterns and processes controlling methylmercury (MeHg) production, bioaccumulation, and export from natural and agricultural wetlands of the Yolo Bypass Wildlife Area (YBWA). The data were collected in conjuntion with a Proposition 40 grant from the State Water Resources Control Board in...

2010, Invasive Plant Science and Management (3) 365-375
The number of invasive exotic plant species establishing in the United States is continuing to rise. When prevention of exotic species from entering into a country fails at the national level and the species establishes, reproduces, spreads, and becomes invasive, the most successful action at a local level is early...

Measurement-derived heat-budget approaches for simulating coastal wetland temperature with a hydrodynamic model
Eric Swain, Jeremy Decker
2010, Wetlands (30) 635-648
Numerical modeling is needed to predict environmental temperatures, which affect a number of biota in southern Florida, U.S.A., such as the West Indian manatee (Trichechus manatus), which uses thermal basins for refuge from lethal winter cold fronts. To numerically simulate heat-transport through a dynamic coastal wetland region, an algorithm was...

2010, North American Journal of Fisheries Management (30) 1365-1369
We designed a digital underwater video camera system to monitor nesting centrarchid behavior in the Tallapoosa River, Alabama, 20 km below a peaking hydropower dam with a highly variable flow regime. Major components of the system included a digital video recorder, multiple underwater cameras, and specially fabricated substrate stakes. The...
