Estimation of lake-scale stock-recruitment models for Great Lakes sea lampreys
Jean V. Adams, Michael L. Jones
2022, Ecological Modelling (467)
Understanding recruitment dynamics is an essential part of effective fisheries management, whether the focus is on conservation, harvest policy development, or invasive species control. We developed a model that estimates lake-wide Ricker stock-recruitment relations for invasive sea lampreys (Petromyzon marinus) in each of the five Laurentian Great Lakes to inform future control efforts....

Glen Torridon is a topographic trough located on the slope of Aeolis Mons, Gale crater, Mars. It corresponds to what was previously referred to as the “clay-bearing unit”, due to the relatively strong spectral signatures of clay minerals (mainly ferric smectites) detected from orbit. Starting in January 2019, the Curiosity...

Allison H. Roy, Emily Bjerre, Jonathon Cummings, Kevin Kalasz, Jason Carmignani, Peter Hazelton, Morgan Kern, David Perkins, Laura Saucier, Ayla J. Skorupa, Rachel Katz, Christy C. Coghlan
2022, Cooperator Science Series CSS-141-2022
In February 2020, we held a workshop where we sought to identify where states should reintroduce or augment brook floater to minimize the probability of extinction within a state. We focused on Massachusetts and Connecticut, two states with only a few, small populations still extant, that likely need population restoration...
An efficient, analytic solution using order statistics for probabilistic seismic‐hazard assessment without the Poisson assumption
Andrew J. Michael, Andrea L. Llenos
2022, Bulletin of the Seismological Society of America (112) 1678-1693
Standard approaches to probabilistic seismic‐hazard assessment (PSHA) assume that earthquakes are random, independent events that follow a Poisson distribution of occurrences in a given time period (Cornell, 1968). To overcome the limitations of the Poisson assumption, such as ignoring earthquake...
Calibration of an evapotranspiration algorithm in a semiarid sagebrush steppe using a 3-ha lysimeter and Landsat normalized difference vegetation index data
Christopher J. Jarchow, William J. Waugh, Pamela L. Nagler
2022, Ecohydrology (15)
In arid and semiarid environments, evapotranspiration (ET) is the primary discharge component in the water balance, with potential ET exceeding precipitation. For this reason, reliable estimates of ET are needed to construct accurate water budgets in these environments. Remote sensing affords the ability to provide fast,...

Northern long-eared bats in the central Appalachians following white-nose syndrome: Failed maternity colonies?
Nicholas J. Kalen, Michael S. Muthersbaugh, Joshua B. Johnson, Alexander Silvis, W. Mark Ford
2022, Journal of the Southeastern Association of Fish and Wildlife Agencies (9) 159-167
Northern long-eared bat (Myotis septentrionalis) populations have experienced severe declines in eastern North America from white-nose syndrome (WNS), yet potential secondary effects on maternity roosting and recruitment remain largely unknown. We documented female day- roosting at two locations in the central Appalachians of Virginia, Back Creek Mountain (BCM) and Rapidan Camp...
Multiple resource limitation of dryland soil microbial carbon cycling on the Colorado Plateau
Ryan T. Choi, Sasha C. Reed, Colin Tucker
2022, Ecology (103)
Understanding interactions among biogeochemical cycles is increasingly important as anthropogenic alterations of global climate and of carbon (C), nitrogen (N), and phosphorus (P) cycles interactively affect the Earth system. Ecosystem processes in the dryland biome, which makes up over 40% of Earth's terrestrial surface, are often distinctively sensitive to small...

In the central Appalachians of Virginia and West Virginia, the Virginia northern flying squirrel (Glaucomys sabrinus fuscus; VNFS) is a subspecies of northern flying squirrel generally associated with red spruce (Picea rubens)-dominated forests at high elevations. Listed as endangered by theU.S. Fish and Wildlife Service from 1985 to 2013, the...
Predicting geothermal favorability in the western United States by using machine learning: Addressing challenges and developing solutions
Stanley Paul Mordensky, John Lipor, Jacob DeAngelo, Erick R. Burns, Cary Ruth Lindsey
2022, Conference Paper, Proceedings, 47th workshop on geothermal reservoir engineering
Previous moderate- and high-temperature geothermal resource assessments of the western United States utilized weight-of-evidence and logistic regression methods to estimate resource favorability, but these analyses relied upon some expert decisions. While expert decisions can add confidence to aspects of the modeling process by ensuring only reasonable models are employed, expert...
Interannual colony exchange among breeding Eastern Brown Pelicans
Bradley P. Wilkinson, Patrick G.R. Jodice
2022, Journal of Field Ornithology (93)
Colonial seabirds often display high rates of interannual site fidelity to breeding locations, especially as adults. Species using more nearshore or coastal systems, however, may display comparatively less fidelity than highly pelagic species. We used long-term GPS tracking data to assess the frequency of interannual colony switching in Eastern Brown...

Environmental exposure to active pharmaceutical ingredients (APIs) can have negative effects on the health of ecosystems and humans. While numerous studies have monitored APIs in rivers, these employ different analytical methods, measure different APIs, and have ignored many of the countries of the world. This makes it difficult to quantify...

2022, Water Resources Research (58)
How precipitation (P) is translated into streamflow (Q) and over what timescales (i.e., “memory”) is difficult to predict without calibration of site-specific models or using geochemical approaches, posing barriers to prediction in ungauged basins or advancement of general theories. Here, we used a data-driven approach to identify regional patterns and...
