2023, Current Research in Parasitology & Vector-borne Diseases (3)
Sylvatic plague, a primarily flea-borne zoonosis, is a significant threat to prairie dogs (Cynomys spp., PDs) and their specialized predators, endangered black-footed ferrets (Mustela nigripes, BFFs). Host-fed fipronil baits have proven effective in controlling fleas on PDs for the purposes of plague mitigation and BFF conservation. Currently, annual treatments are the norm. We tested the long-term efficacy of fipronil bait...
Establishing an in vitro model to assess the toxicity of 6PPD-quinone and other tire wear transformation products
Justin Blaine Greer, Ellie Maureen Dalsky, Rachael F. Lane, John Hansen
2023, Environmental Science and Technology Letters (10) 533-537
The tire wear transformation product 6PPD-quinone (6PPDQ) has been implicated as the causative factor for broad scale mortality events for coho salmon in the Pacific Northwest. Highly variable sensitivity to 6PPDQ in closely related salmonids complicates efforts to evaluate the broader toxicological impacts to aquatic ecosystems. Our goals were to...

2023, Ecological Monographs (93)
Symbiotic nitrogen fixation (SNF) is a key ecological process whose impact depends on the strategy of SNF regulation—the degree to which rates of SNF change in response to limitation by N versus other resources. SNF that is obligate or exhibits incomplete downregulation can result in excess N fixation, whereas a...
Is now the time? Review of genetic rescue as a conservation tool for brook trout
Shannon L. White, Jacob M Rash, David C. Kazyak
2023, Ecology and Evolution (13)
Brook trout populations have been declining throughout their native range in the east coast of the United States. Many populations are now distributed in small, isolated habitat patches where low genetic diversity and high rates of inbreeding reduce contemporary viability and long-term adaptive potential. Although...
The truth is in the stream: Use of tracer techniques and synoptic sampling to evaluate metal loading and remedial options in a hydrologically complex setting
Robert L. Runkel, Philip Verplanck, Katherine Walton-Day, R. Blaine McCleskey, Patrick Byrne
2023, Science of the Total Environment (876)
Two synoptic sampling campaigns were conducted to quantify metal loading to Illinois Gulch, a small stream affected by historical mining activities. The first campaign was designed to determine the degree to which Illinois Gulch loses water to the underlying mine workings, and to determine the effect of these losses on observed metal loads....
Application of habitat association models across regions: Useful explanatory power retained in wetland bird case study
Lisa H. Elliott, Annie M. Bracey, Gerald J. Niemi, Douglas H. Johnson, Thomas M. Gehring, Erin E. Gnass Giese, Giuseppe E. Fiorino, Robert W. Howe, Gregory J. Lawrence, Christopher J. Norment, Douglas C. Tozer, Lawrence Igl
2023, Ecosphere (14)
Species often exhibit regionally specific habitat associations, so habitat association models developed in one region might not be accurate or even appropriate for other regions. Three programs to survey wetland-breeding birds covering (respectively) Great Lakes coastal wetlands, inland Great Lakes wetlands, and the Prairie Pothole Region offer an opportunity to...
Introduction to the digitization of seismic data: A user’s guide
Adam T. Ringler, Robert E. Anthony, Patrick Bastien, Adam Pascale, Bion J. Merchant
2023, Seismological Research Letters (94) 2060-2074
Modern seismic data are collected, distributed, and analyzed using digital formats, and this has become a standard for the field. Although most modern seismometers still make use of analog electronic circuits, their data are converted from an analog voltage output to time‐tagged counts...
Gene expression and wildlife health: Varied interpretations based on perspective
Lizabeth Bowen, Julie L. Yee, James L. Bodkin, Shannon C. Waters, Michael J. Murray, Heather Coletti, Brenda E. Ballachey, Daniel Monson, A. Keith Miles
2023, Frontiers in Ecology and Evolution (11)
We evaluated wildlife population health from the perspective of statistical means vs. variances. We outlined the choices necessary to provide the framework for our study. These consisted of spatial and temporal boundaries (e.g., choice of sentinel species, populations, time frame), measurement techniques (molecular to population level), and appropriate statistical analyses....
Recognizing political influences in participatory social-ecological systems modeling
Theodore C. Lim, Pierre D. Glynn, Gary W. Shenk, Patrick Bitterman, Joseph H. A. Guillaume, John Little, D. G. Webster
2023, Socio-Environmental Systems Modelling (5)
Stakeholder participation in social-ecological systems (SES) modeling is increasingly considered a desirable way to elicit diverse sources of knowledge about SES behavior and to promote inclusive decision-making in SES. Understanding how participatory modeling processes function in the context of long-term adaptive management of SES may allow for better design of...
Sensitivity of the Penman-Monteith reference evapotranspiration equation to meteorological variables for Puerto Rico
Michelle M. Irizarry-Ortiz, Eric Harmsen
2023, Hydrology (10)
Spatiotemporal variations in reference evapotranspiration (ETo) are sensitive to the meteorological data used in its estimation. The sensitivity of the ASCE standardized ETo equation to meteorological variables from GOES-PRWEB dataset was evaluated for the island of Puerto Rico. Island wide, ETo is most sensitive to daily mean relative humidity (RHmean), followed...

John B. Loomis, Lucas Bair
2023, Book chapter, Oxford research encyclopedia of environmental science
Outdoor recreation is an important and growing activity worldwide. Water-based outdoor recreation is a subset that includes various activities such as fishing, boating, and swimming. While a large portion of water-based recreation is either free or provided at administratively set minimal entrance fees, these activities still involve significant economic value...

2023, Conference Paper, Proceedings of SEDHYD 2023
Acoustic instrumentation can be used to provide time-series and discrete estimates of suspended-sediment concentration, load, and sediment particle sizes in fluvial systems, which are essential for creating informed solutions to many sediment-related environmental, engineering, and land management concerns. Historically, scientists have developed relations between suspended sediment characteristics and other parameters,...

Matthew A. Thomas, Donald N. Lindsay, David B. Cavagnaro, Jason W. Kean, Scott W. McCoy, Andrew Paul Graber
2023, Geophysical Research Letters (50)
Increased wildfire activity in the western United States has exposed regional gaps in our understanding of postfire debris-flow generation. To address this problem, we characterized flows in an unstudied area to test the rainfall intensity-duration control of the hazard. Our rainfall measurements and field observations from the northern Sierra Nevada...
