Applying downscaled global climate model data to a hydrodynamic surface-water and groundwater model
Eric Swain, Lydia Stefanova, Thomas Smith
2014, American Journal of Climate Change (3) 33-49
Precipitation data from Global Climate Models have been downscaled to smaller regions. Adapting this downscaled precipitation data to a coupled hydrodynamic surface-water/groundwater model of southern Florida allows an examination of future conditions and their effect on groundwater levels, inundation patterns, surface-water stage and flows, and salinity. The downscaled rainfall data...

Steven K. Sando, Aldo V. Vecchia, David L. Lorenz, Elliott P. Barnhart
2014, Scientific Investigations Report 2013-5217
A large-scale trend analysis was done on specific conductance, selected trace elements (arsenic, cadmium, copper, iron, lead, manganese, and zinc), and suspended-sediment data for 22 sites in the upper Clark Fork Basin for water years 1996–2010. Trend analysis was conducted by using two parametric methods: a time-series model (TSM) and...
Soil compaction vulnerability at Organ Pipe Cactus National Monument, Arizona
Robert H. Webb, Kenneth E. Nussear, Shinji Carmichael, Todd C. Esque
2014, Open-File Report 2014-1048
Compaction vulnerability of different types of soils by hikers and vehicles is poorly known, particularly for soils of arid and semiarid regions. Engineering analyses have long shown that poorly sorted soils (for example, sandy loams) compact to high densities, whereas well-sorted soils (for example, eolian sand) do not compact, and...

2014, Data Series 711
During January and February 2011 the U.S. Geological Survey (USGS), in cooperation with the University of South Florida (USF), conducted geochemical surveys on the west Florida Shelf. Data collected will allow USGS and USF scientists to investigate the effects of climate change on ocean acidification within the northern Gulf of...
Genetic variation in bacterial kidney disease (BKD) susceptibility in Lake Michigan Chinook Salmon and its progenitor population from the Puget Sound
Maureen K. Purcell, Jeffrey J. Hard, Kathleen G. Neely, Linda K. Park, James R. Winton, Diane G. Elliott
2014, Journal of Aquatic Animal Health (26) 9-18
Mass mortality events in wild fish due to infectious diseases are troubling, especially given the potential for long-term, population-level consequences. Evolutionary theory predicts that populations with sufficient genetic variation will adapt in response to pathogen pressure. Chinook Salmon Oncorhynchus tshawytscha were introduced into Lake Michigan in the late 1960s from...

Jennifer C. Murphy, Robert M. Hirsch, Lori A. Sprague
2014, Hydrology and Earth System Sciences 967-979
The relationship between antecedent flow conditions and nitrate concentrations was explored at eight sites in the 2.9 million square kilometers (km2) Mississippi River basin, USA. Antecedent flow conditions were quantified as the ratio between the mean daily flow of the previous year and the mean daily flow from the period...

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...

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...

Despite...
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...

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....

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...
