Teresa J. Newton, Michael A. Boogaard, Nicholas Schloesser, Courtney Kirkeeng, Justin Schueller, Sherwin G. Toribio
2023, Journal of Great Lakes Research (49) 303-317
The lampricides TFM (3-trifluoromethyl-4′-nitrophenol) and Niclosamide (NIC, 2′, 5-dichloro-4′-nitrosalicylanilide) are used to control sea lamprey populations in the Great Lakes and associated tributaries. Niclosamide is often used as an additive to TFM to reduce the amount of TFM required to control sea lamprey. Concern is growing over the risk that...
Ecology and ecosystem impacts of submerged and floating aquatic vegetation in the Sacramento-San Joaquin Delta
Mairgareth A. Christman, Shruti Khanna, Judith Z. Drexler, Matthew J. Young
2023, San Francisco Estuary and Watershed Science (20)
Substantial increases in non-native aquatic vegetation have occurred in the upper San Francisco Estuary over the last 2 decades, largely from the explosive growth of a few submerged and floating aquatic plant species. Some of these species act as ecosystem engineers by creating conditions that favor their further growth and...

Jessica N. Hightower, Dolly L. Crawford, Wayne E. Thogmartin, Kyle R. Aldinger, Sara Barker Swarthout, David A. Buehler, John Confer, Christian Friis, Jeff Larkin, James D. Lowe, Martin Piorkowski, Ronald W. Rohrbaugh, Kenneth V. Rosenberg, Curtis G. Smalling, Petra B. Wood, Rachel Vallender, Amber M. Roth
2023, Diversity and Distributions (29) 254-271
AimClimate change is affecting the distribution of species and subsequent biotic interactions, including hybridization potential. The imperiled Golden-winged Warbler (GWWA) competes and hybridizes with the Blue-winged Warbler (BWWA), which may threaten the persistence of GWWA due to introgression. We examined how climate change is likely to alter...

2023, Persoonia - Molecular Phylogeny and Evolution of Fungi (50) 27-47
Arthroderma is the most diverse genus of dermatophytes, and its natural reservoir is considered to be soil enriched by keratin sources. During a study on the diversity of dermatophytes in wild small rodents in the Czech Republic, we isolated several strains of Arthroderma. To explore the...
Where forest may not return in the western United States
James Wickham, Anne Neale, Kurt H. Riitters, Maliha Nash, Jon Dewitz, Suming Jin, Megan van Fossen, D Rosenbaum
2023, Ecological Indicators (146)
Droughts that are hotter, more frequent, and last longer; pest outbreaks that are more extensive and more common; and fires that are more frequent, more extensive, and perhaps more severe have raised concern that forests in the western United States may not...
Does hatchery rearing of lake trout affect their reproductive behavior in the wild?
Thomas Binder, Christopher Holbrook, Charles R. Bronte, Ji He, Charles Kreuger
2023, Journal of Great Lakes Research (49) 288-302
Stocking of hatchery-reared fishes has been used with variable success as a management action to promote the recovery of populations and species. The practice has been controversial for several reasons, including uncertainty about whether the hatchery rearing experience may affect reproduction...

Michael E. Fraker, Noel R Aloysius, Jay F. Martin, S. Conor Keitzer, David A Dippold, Haw Yen, Jeffrey G. Arnold, Prasad Daggupati, Mari-Vaughn Virginia Johnson, Dale M. Robertson, Scott P. Sowa, Michael J. White, Stuart A. Ludsin
2023, Journal of Great Lakes Research (49) 209-219
Harmful algal blooms (HABs) are a recurring problem in many temperate large lake and coastal marine ecosystems, caused mainly by anthropogenic eutrophication. Implementation of agricultural conservation practices (ACPs) offers a means to reduce non-point source nutrient runoff and mitigate HABs. However,...

2023, Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science (15)
The Penobscot River Restoration Project in Maine was a large river rehabilitation project that culminated in the removal of the two lowermost dams and improvements to fish passage on several remaining dams. Fish assemblages were surveyed for 3 years prior to rehabilitation, 3 years after rehabilitation, and 8 years after rehabilitation. Approximately 475 km...
Effects of freshwater residence time on reproductive success in anadromous alewife (Alosa pseudoharengus): climate change implications
Meghna N. Marjadi, Allison H. Roy, Matthew T. Devine, Benjamin I. Gahagan, Adrian Jordaan, Julianne Rosset, Andrew R. Whiteley
2023, Canadian Journal of Fisheries and Aquatic Sciences (80) 563-576
Earlier spring warming and anadromous fish migrations prompted by climate change are linked to shorter freshwater residency. Impacts of phenological change on anadromous fish populations are poorly understood with limited studies focused on iteroparous non-salmonids. We assessed freshwater residence time and reproductive success in an iteroparous clupeid, alewife (Alosa pseudoharengus)...

S. Bayuzick, D. Guarin, J. Benavides, A. Bonhage, F. Hirsch, Duane R. Diefenbach, M. McDill, T. Raab, P.J. Drohan
2023, Geomorphology (422)
Hearths used for 19th and 20th century charcoal manufacturing have been found to have unique plant communities or to produce unique growth characteristics for some species but not others. Given known differences in hearth morphology, within hearth physical and chemical differences may exist and result in unique ecologic niches. We...

2023, Conservation Science and Practice (5)
Resource managers have rarely accounted for evolutionary dynamics in the design or implementation of climate change adaptation strategies. We brought the research and management communities together to identify challenges and opportunities for applying evidence from evolutionary science to support on-the-ground actions intended to enhance species' evolutionary potential. We amalgamated input...

Kenneth Tiffan, Brad Liedtke, Dalton Dirk Lebeda, Scott Louis Benson, Joe J. Warren
2023, Report
In 2020, a new spill program was implemented to aid the downstream passage of juvenile salmonids at mainstem dams on the Snake and Columbia rivers. Under this program, the total dissolved gas (TDG) cap was increased to 125% and monitoring of native nonsalmonids for gas bubble trauma (GBT) became a...

Joint spatiotemporal models to predict seabird densities at sea
Mayumi L. Arimitsu, John F. Piatt, James Thorson, Kathy Kuletz, Gary Drew, Sarah K. Schoen, Dan Cushing, Caitlin Kroeger, William Sydeman
2023, Frontiers in Marine Science (10)
Introduction: Seabirds are abundant, conspicuous members of marine ecosystems worldwide. Synthesis of distribution data compiled over time is required to address regional management issues and understand ecosystem change. Major challenges when estimating seabird densities at sea arise from variability in dispersion of the birds, sampling effort over time and space, and...
Can hydrological models benefit from using global soil moisture, evapotranspiration, and runoff products as calibration targets?
Yiwen Mei, Juliane Mai, Hong Xuan Do, Andrew Gronewold, Howard W. Reeves, Sandra M. Eberts, Richard G. Niswonger, R. Steve Regan, Randall J. Hunt
2023, Water Resources Research (59)
Hydrological models are usually calibrated to in-situ streamflow observations with reasonably long and uninterrupted records. This is challenging for poorly gage or ungaged basins where such information is not available. Even for gaged basins, the single-objective calibration to gaged streamflow cannot guarantee reliable forecasts because, as has...

Daniel M. Griffith, Kristin B. Byrd, Nicole Chin Taylor, Elijah Allan, Liz Bittner, Bart O’Brien, V. Thomas Parker, Michael C Vasey, Ryan Pavlick, Ramakrishna R. Nemani
2023, Journal of Geophysical Research: Biogeosciences (128)
Evolutionary relatedness underlies patterns of functional diversity in the natural world. Hyperspectral remote sensing has the potential to detect these patterns in plants through inherited patterns of leaf reflectance spectra. We collected leaf reflectance data from across the California flora from plants grown in a common garden....
Linear regression model documentation for computing water-quality constituent concentrations or densities using continuous real-time water-quality data for the Kansas River above Topeka Weir at Topeka, Kansas, November 2018 through June 2021
Thomas J. Williams
2023, Scientific Investigations Report 2022-5130
The Kansas River and its associated alluvial aquifer provide drinking water to more than 950,000 people in northeastern Kansas. Water suppliers that rely on the Kansas River as a water-supply source use physical and chemical processes to treat and remove contaminants before public distribution. An early-notification system of changing water-quality...
