2020, Scientific Investigations Map 3457
The Bighorn Basin is a large intermontane sedimentary and structural basin that formed during the Laramide orogeny. The first commercial hydrocarbon production in the Bighorn Basin was established in 1906 from Cretaceous reservoirs at Garland field followed by the discovery of Greybull field in 1907. Since then, many important conventional...

Ben S Breaker, Kevin L. Pangle, Kevin Donner, Jason Smith, Benjamin A. Turschak, Randall M. Claramunt, David Bunnell, Jory L. Jonas
2020, Journal of Great Lakes Research (46) 1402-1411
Contemporary conditions in Lake Michigan where cisco (Coregonus artedi) populations are expanding are vastly different from those encountered by the historic fish community. Invasive species introductions have substantially altered the Lake Michigan ecosystem in the last half century. Successful management efforts for cisco in Lake Michigan hinge on our ability...

Anticoagulant rodenticides are widely used for rodent control in agricultural and urban settings. Their intense use can sometimes result in accidental exposure and even poisoning of livestock. Can milk, eggs or meat derived from such accidentally exposed animals be consumed by humans? Data on the pharmacokinetics of chlorophacinone in milk...

Isabella A. Oleksy, Whitney Beck, R. Lammers, Cara Steger, Cody Wilson, Kyle Christensen, Kim Vincent, Pieter Johnson, Jill Baron
2020, Ecology (101)
Abstract Climate change is altering biogeochemical, metabolic, and ecological functions in lakes across the globe. Historically, mountain lakes in temperate regions have been unproductive due to brief ice-free seasons, a snowmelt-driven hydrograph, cold temperatures, and steep topography with low vegetation and soil cover. We tested the relative importance of winter and...

Dakota M. Churchill, Michael Manga, Shaul Hurwitz, Sara Peek, Joseph Licciardi, James B. Paces
2020, Journal of Volcanology and Geothermal Research (402)
We describe a new effort to date hydrothermal silica sinter deposits (geyserite) from the Upper Geyser Basin of Yellowstone National Park using 14C of co-deposited organic matter, U-series and cosmogenic 10Be methods. A majority of the samples were collected from stratigraphic sections, mainly at Riverside, Giant, and Castle Geysers. Ages...

Tanja N. Williamson, Chris D. Barton
2020, Science of the Total Environment (743)
Forests in the Appalachian region of the U.S. are threatened by a variety of short- and long-term pressures, including climate change, invasive species, and resource extraction. Surface mining for coal is one of the most important drivers of land-use...
Indexing age-0 Walleye abundance in northern Wisconsin lakes Before fall
Hadley I. A. Boehm, Jason C. Gostiaux, Gretchen J. A. Hansen, Daniel A. Isermann
2020, North American Journal of Fisheries Management (40) 910-921
Age-0 Walleye Sander vitreus recruitment is often indexed using fall electrofishing surveys. However, collecting fish before fall may provide timely information regarding stocking decisions and factors influencing recruitment. We evaluated sampling methods for age-0 Walleye in northern Wisconsin lakes that could be used to assess recruitment in spring and summer....
Validating deployment of aerially delivered toxic bait cartridges for control of invasive brown treesnakes
Scott Michael Goetz, Amy A. Yackel Adams, Shane S Siers
2020, Wildlife Society Bulletin (44) 617-622
Aerial application of management tools can provide a cost‐effective means to conserve or control wildlife populations at the landscape scale. Large spatial scales, however, present difficulties when assessing in situ reliability and integrity of the devices themselves. We demonstrate application of a distance‐sampling density estimation approach to assess the performance of a...

2020, Journal of Environmental Modelling and Software (134)
Large-scale computational investigations of groundwater levels are proposed to accelerate science delivery through a workflow spanning database assembly, statistics, and information synthesis and packaging. A water-availability study of the Mississippi River alluvial plain, and particularly the Mississippi River Valley alluvial aquifer...
msocc: Fit and analyse computationally efficient multi‐scale occupancy models in R
Christian Stratton, Adam J. Sepulveda, Andrew B. Hoegh
2020, Methods in Ecology and Evolution (11) 1113-1120
Environmental DNA (eDNA) sampling is a promising tool for the detection of rare and cryptic taxa, such as aquatic pathogens, parasites and invasive species. Environmental DNA sampling workflows commonly rely on multi‐stage hierarchical sampling designs that induce complicated dependencies within the data. This complex dependence structure can be intuitively...

Olivia M. Cheriton, Curt D. Storlazzi, Kurt J. Rosenberger
2020, Frontiers in Marine Science (7)
The character and energetics of infragravity (IG, 25 s 250 s) waves over coral reef flats can enhance shoreline erosion or accretion, and also govern extreme shoreline events such as runup, overwash, and flooding on coral reef-lined coasts. Here...
Selective sediment transport during Hurricane Sandy on Fire Island (New York, USA): Inferences from heavy-mineral assemblages
Joao Cascalho, Pedro Costa, Guy R. Gelfenbaum, SeanPaul La Selle, Bruce E. Jaffe
2020, Journal of Sedimentary Research (90) 269-285
In October 2012, Hurricane Sandy caused severe erosion on beaches and dunes of Fire Island (New York, USA). Major shoreline changes occurred with erosional dominance in the upper shoreline and aggradation in the lowermost section of the beach due to the deposition of eroded upper beach and dune sediment. Sand...

Lucas P Griffin, Brian J. Smith, Michael Cherkiss, Andrew Crowder, Clayton G Pollock, Zandy Hillis-Starr, Andy J. Danylchuk, Kristen Hart
2020, Animal Biotelemetry (8)
Background A better understanding of sea turtle spatial ecology is critical for the continued conservation of imperiled sea turtles and their habitats. For resource managers to develop the most effective conservation strategies, it is especially important to examine how turtles use and select for habitats within their developmental foraging grounds. Here,...

2020, Journal of Fish and Wildlife Management (11) 287-299
We studied the ecological health of springs experiencing varying levels of urban development to assess impacts to rare endemic salamanders (Eurycea spp.) of Central Texas. We evaluated measures of invertebrate species richness, water quality, and contaminant uptake by salamanders to determine how springs and their inhabitants were being affected by urban...

2020, PLoS ONE (15)
To investigate a Florida manatee (Trichechus manatus latirostris) mortality event following a red tide bloom in Southwest Florida, an RNA sequencing experiment was conducted. Gene expression changes in white blood cells were assessed in manatees rescued from a red tide affected area (n = 4) and a control group (n...

Animals exhibit a diversity of movement tactics [1]. Tracking resources that change across space and time is predicted to be a fundamental driver of animal movement [2]. For example, some migratory ungulates (i.e., hooved mammals) closely track the progression of highly nutritious plant green-up, a phenomenon called “green-wave surfing” [3-5]....
Wildfire-driven changes in hydrology mobilize arsenic and metals from legacy mine waste
Sheila F. Murphy, R. Blaine McCleskey, Deborah A. Martin, JoAnn M. Holloway, Jeffrey H. Writer
2020, Science of the Total Environment (743)
Wildfires burning in watersheds that have been mined and since revegetated pose unique risks to downstream water supplies. A wildfire near Boulder, Colorado that burned a forested watershed recovering from mining disturbance that occurred 80-160 years ago allowed us to 1) assess arsenic and metal contamination in streams draining the...

2020, Science of the Total Environment (743)
Mercury concentrations in freshwater food webs are governed by complex biogeochemical and ecological interactions that spatially vary and are often mediated by climate. The Arctic Coastal Plain of Alaska (ACP) is a heterogeneous, lake-rich landscape where variability in mercury accumulation is poorly understood. Earlier...

Development of a new open-source tool to map burned area and burn severity
Joshua J. Picotte
2020, Conference Paper, Proceedings of the fire continuum- Preparing for the future of wildland fire
Accurate and complete geospatial fire occurrence records are important in determining postfire effects, emissions, hazards, and fuel loading inventories. Currently, the Monitoring Trends in Burn Severity (MTBS) project maps the fire perimeter and burn severity of all large fires on public lands. Although the MTBS project maps a large proportion...
