Sarah H. Olson, Jane Parmley, Catherine Soos, Martin Gilbert, Neus Latore-Margalef, Jeffrey S. Hall, Phillip M. Hansbro, Frank Leighton, Vincent Munster, Damien Joly
2014, PLoS ONE (9)
Wild aquatic birds are recognized as the natural reservoir of avian influenza A viruses (AIV), but across high and low pathogenic AIV strains, scientists have yet to rigorously identify most competent hosts for the various subtypes. We examined 11,870 GenBank records to provide a baseline inventory and insight into patterns...

James W. Rivers, Matthew J. Johnson, Susan M. Haig, Carl J. Schwarz, Joseph Burnett, Joseph Brandt, Daniel George, Jesse Grantham
2014, Bird Conservation International (24) 492-504
Condors and vultures comprise the only group of terrestrial vertebrates in the world that are obligate scavengers, and these species move widely to locate ephemeral, unpredictable, and patchily-distributed food resources. In this study, we used high-resolution GPS location data to quantify monthly home range size of the critically endangered California...
Biological soil crusts (biocrusts) as a model system in community, landscape and ecosystem ecology
Matthew A. Bowker, Fernando T. Maestre, David Eldridge, Jayne Belnap, Andrea Castillo-Monroy, Cristina Escolar, Santiago Soliveres
2014, Biodiversity and Conservation (23) 1619-1637
Model systems have had a profound influence on the development of ecological theory and general principles. Compared to alternatives, the most effective models share some combination of the following characteristics: simpler, smaller, faster, general, idiosyncratic or manipulable. We argue that biological soil crusts (biocrusts) have unique combinations of these features...
Evaluation of the expected moments algorithm and a multiple low-outlier test for flood frequency analysis at streamgaging stations in Arizona
Nicholas V. Paretti, Jeffrey R. Kennedy, Timothy A. Cohn
2014, Scientific Investigations Report 2014-5026
Flooding is among the costliest natural disasters in terms of loss of life and property in Arizona, which is why the accurate estimation of flood frequency and magnitude is crucial for proper structural design and accurate floodplain mapping. Current guidelines for flood frequency analysis in the United States are described...

The first ever regional thermal properties map of Vesta has been derived from the temperatures retrieved by infrared data by the mission Dawn. The low average value of thermal inertia, 30 ± 10 J m−2 s−0.5 K−1, indicates a surface covered by a fine regolith. A range of thermal inertia values suggesting terrains with...
Fishing for resilience
Kevin L. Pope, Craig R. Allen, D.G. Angeler
2014, Transactions of the American Fisheries Society (143) 467-478
Management approaches that focus on social–ecological systems—systems comprised of ecosystems, landscapes, and humans—are needed to secure the sustainability of inland recreational fisheries without jeopardizing the integrity of the underlying social and ecological components. Resilience management can be useful because it focuses on providing recreational capacity for fishermen under a variety...

2014, Book, International Conference on Pattern Recognition Applications and Methods
Principal component analysis is used to implement a semi-automatic recognition system to identify recaptured northern leopard frogs (Lithobates pipiens). Results of both open set and closed set experiments are given. The presented algorithm is shown to provide accurate identification of 209 individual leopard frogs from a total set of 1386...
Development and evaluation of a blocking enzyme-linked immunosorbent assay and virus neutralization assay to detect antibodies to viral hemorrhagic septicemia virus
Anna Wilson, Tony Goldberg, Susan Marcquenski, Wendy Olson, Frederick Goetz, Paul Hershberger, Lucas M. Hart, Kathy Toohey-Kurth
2014, Clinical and Vaccine Immunology (21) 435-442
Viral hemorrhagic septicemia virus (VHSV) is a target of surveillance by many state and federal agencies in the United States. Currently, the detection of VHSV relies on virus isolation, which is lethal to fish and indicates only the current infection status. A serological method is required to ascertain prior exposure....

Susan C. Walls, J. Hardin Waddle, Stephen P. Faulkner
2014, Wetlands (34) 197-207
We measured amphibian habitat use to quantify the effectiveness of conservation practices implemented under the Wetland Reserve Program (WRP), an initiative of the U.S. Department of Agriculture’s Natural Resources Conservation Service.

A missing dimension in measures of vaccination impacts
M. Gabriela M. Gomes, Andrew Wargo, Marc Lipsitch, Gael Kurath, Carlota Rebelo, Graham F. Medley, Antonio Coutinho
2014, PLoS Pathogens (10)
Immunological protection, acquired from either natural infection or vaccination, varies among hosts, reflecting underlying biological variation and affecting population-level protection. Owing to the nature of resistance mechanisms, distributions of susceptibility and protection entangle with pathogen dose in a way that can be decoupled by adequately representing the dose dimension. Any...

2014, Nature (507) 90-93
Forests are major components of the global carbon cycle, providing substantial feedback to atmospheric greenhouse gas concentrations. Our ability to understand and predict changes in the forest carbon cycle—particularly net primary productivity and carbon storage - increasingly relies on models that represent biological processes across several scales of biological organization,...
Atrazine reduces reproduction in fathead minnow (Pimephales promelas): raw data report
Donald E. Tillitt, Diana M. Papoulias, Jeffrey J. Whyte, Cathy A. Richter
2014, Data Series 805
The herbicide, atrazine, routinely is observed in surface and groundwaters, particularly in the “corn belt” region, a high-use area of the United States. Atrazine has demonstrated effects on reproduction in mammals and amphibians, but the characterization of endocrine-related effects in fish has received only limited attention. Peak concentrations of atrazine...

2014, Science of the Total Environment (470-471) 1313-1319
We determined whole-fish total mercury (Hg) concentrations of 40 male and 40 female adult sea lampreys (Petromyzon marinus) captured in the Cheboygan River, a tributary to Lake Huron, during May 2011. In addition, bioenergetics modeling was used to explore the effects of sex-related differences in activity and resting (standard) metabolic...

Tobias J. Kock, Theresa L. Liedtke, Brian K. Ekstrom, Ryan G. Tomka, Dennis W. Rondorf
2014, Open-File Report 2014-1042
Collection of juvenile salmonids at Cowlitz Falls Dam is a critical part of the effort to restore salmon in the upper Cowlitz River because the majority of fish that are not collected at the dam pass downstream and enter a large reservoir where they become landlocked and lost to the...
Sex in the Suwannee, the secretive love life of Gulf Sturgeons
Kenneth J. Sulak
2014, American Currents (39) 22-24
Mid-February in the Gulf of Mexico and a timeless ritual is about to repeat itself for perhaps the millionth time. Some mysterious signal, possibly increasing day length, flips an internal switch, feeding stops, and the homeward migration begins for the Gulf Sturgeon (Acipenser oxyrinchus desotoi). From far flung places along...

Philip L. Verplanck, Bradley S. Van Gosen, Robert R. Seal II, Anne E. McCafferty
2014, Scientific Investigations Report 2010-5070-J
Carbonatite and alkaline intrusive complexes, as well as their weathering products, are the primary sources of rare earth elements. A wide variety of other commodities have been exploited from carbonatites and alkaline igneous rocks including niobium, phosphate, titanium, vermiculite, barite, fluorite, copper, calcite, and zirconium. Other elements enriched in these...
