Burbot Lota lota are distributed across the Laurentian Great Lakes where they occupy a top piscivore role. The St. Clair-Detroit River System is known to provide a migration corridor as well as spawning and nursery habitat for many indigenous fishes of economic and ecological significance. However, knowledge is scant of the...
Small lakes show muted climate change signal in deepwater temperatures
Luke A. Winslow, Jordan S. Read, Gretchen J. A. Hansen, Paul C. Hanson
2015, Geophysical Research Letters (42) 355-361
Water temperature observations were collected from 142 lakes across Wisconsin, USA, to examine variation in temperature of lakes exposed to similar regional climate. Whole lake water temperatures increased across the state from 1990 to 2012, with an average trend of 0.042°C yr−1 ± 0.01°C yr−1. In large (>0.5 km2) lakes, the positive temperature trend was...

Quantifying stream thermal regimes at management-pertinent scales: combining thermal infrared and stationary stream temperature data in a novel modeling framework.
Shane J. Vatland, Robert E. Gresswell, Geoffrey C. Poole
2015, Water Resources Research (51) 31-46
Accurately quantifying stream thermal regimes can be challenging because stream temperatures are often spatially and temporally heterogeneous. In this study, we present a novel modeling framework that combines stream temperature data sets that are continuous in either space or time. Specifically, we merged the fine spatial resolution of thermal infrared...

In 1996, at the request of the Government of the Islamic Republic of Mauritania, a team of U.S. Geological Survey (USGS) scientists produced a strategic plan for the acquisition, improvement and modernization of multidisciplinary sets of data to support the growth of the Mauritanian minerals sector and to highlight the...
Strontium isotopes in otoliths of a non-migratory fish (slimy sculpin): Implications for provenance studies
Sean R. Brennan, Diego P. Fernandez, Christian E. Zimmerman, Thure E. Cerling, Randy J. Brown, Matthew J. Wooller
2015, Geochimica et Cosmochimica Acta (149) 32-45
Heterogeneity in 87Sr/86Sr ratios of river-dissolved strontium (Sr) across geologically diverse environments provides a useful tool for investigating provenance, connectivity and movement patterns of various organisms and materials. Evaluation of site-specific 87Sr/86Sr temporal variability throughout study regions is a prerequisite for provenance research, but the dynamics driving temporal variability are...

2015, Conference Paper, Proceedings volume: Basin and range province seismic hazards summit III, 2015 (Utah Geological Survey Miscellaneous Publication 15-5)
Over the past 25 years, luminescence dating has become a key tool for dating sediments of interest in paleoseismic research. The data obtained from luminescence dating has been used to determine timing of fault displacement, calculate slip rates, and estimate earthquake recurrence intervals. The flexibility of luminescence is a key...

CM Carlson, Jay R. Schneider, Janice C. Pedersen, Dennis M. Heisey, Christopher J. Johnson
2015, Canadian Journal of Veterinary Research (79) 68-73
Meadow voles (Microtus pennsylvanicus) are permissive to chronic wasting disease (CWD) infection, but their susceptibility to other transmissible spongiform encephalopathies (TSEs) is poorly characterized. In this initial study, we intracerebrally challenged 6 meadow voles with 2 isolates of sheep scrapie. Three meadow voles acquired a TSE after the scrapie challenge...

2015, Report
The EU Birds Directive and the African-Eurasian Waterbird Agreement provide an adequate legal framework for sustainable management of migratory waterbird populations. The main shortcoming of both instruments is that it leaves harvest decisions of a shared resource to individual Member States and Contracting Parties without providing a shared information base...

Andrew M. Ramey, Joel A. Schmutz, John A. Reed, Go Fujita, Bradley D. Scotton, Bruce Casler, Joseph P. Fleskes, Kan Konishi, Kiyoshi Uchida, Michael J. Yabsley
2015, International Journal for Parasitology: Parasites and Wildlife (4) 11-21
Empirical evidence supports wild birds as playing a role in the interhemispheric exchange of bacteria and viruses; however, data supporting the redistribution of parasites among continents are limited. In this study, the hypothesis that migratory birds contribute to the redistribution of parasites between continents was tested by sampling northern pintails...

Gregory Fernette
2015, Open-File Report 2013-1280-M
Mauritania hosts one significant copper-gold deposit, Guelb Moghrein and several occurrences, which have been categorized as iron oxide copper-gold (IOCG) deposits but which are atypical in some important respects. Nonetheless, Guelb Moghrein is an economically significant mineral deposit and an attractive exploration target. The deposit is of Archean age and...

Sanjay Mohanty, Mark Bulicek, David W. Metge, Ronald W. Harvey, Joseph N. Ryan, Alexandria B. Boehm
2015, Vadose Zone Journal (14)
Pathogens or biocolloids mobilized in the vadose zone may consequently contaminate groundwater. We found that microspheres were mobilized from a fractured soil during intermittent rainfall and the mobilization was greater when the microsphere size was larger and when the soil had greater water permeability.The vadose zone filters pathogenic microbes from...
Land use structures fish assemblages in reservoirs of the Tennessee River
Leandro E. Miranda, J. M. Bies, D. A. Hann
2015, Marine and Freshwater Research (66) 526-534
Inputs of nutrients, sediments and detritus from catchments can promote selected components of reservoir fish assemblages, while hindering others. However, investigations linking these catchment subsidies to fish assemblages have generally focussed on one or a handful of species. Considering this paucity of community-level awareness, we sought to explore the association...
