Pacific herring (Clupea pallasii), a cornerstone of marine food webs, generally spawn on marine macroalgae in shallow nearshore areas that are disproportionately at risk from oil spills. Herring embryos are also highly susceptible to toxicity from chemicals leaching from oil stranded in intertidal and subtidal zones. The water-soluble components of...
Recharge estimation approach in a data-scarce semi-arid region, Northern Ethiopian Rift Valley
Sisay Simachew Mekonen, Scott E. Boyce, Abdella K. Mohammed, Lorraine E. Flint, Alan L Flint, Markus Disse
2023, Sustainability (15)
Sustainable management of groundwater resources highly relies on the accurate estimation of recharge. However, accurate recharge estimation is a challenge, especially in data-scarce regions, as the existing models are data-intensive and require extensive parameterization. This study developed a process-based hydrologic model combining local and remotely sensed data for characterizing recharge...
Carbon dioxide (CO2) gas and eDNA monitoring as tools for eradicating invasive fish from anchialine pools in Hawai‘i
Robert W. Peck, Maya Munnstermann, Malia Hayes, Carter T. Atkinson, Sallie Beavers, Aaron R. Cupp, Paul C. Banko
2023, Management of Biological Invasions (14) 749-774
Invasive fish can profoundly affect communities they invade. In Hawai‘i, invasive fishes have become established in many anchialine pools, threatening the persistence of resident invertebrates, including several endangered species. Tools to eradicate invasive fishes from these pools are lacking. This study tested the efficacy of carbon dioxide (CO2) gas diffused...

Predicting daily river chlorophyll concentrations at a continental scale
Philip Savoy, Judson Harvey
2023, Water Resources Research (59)
Eutrophication is one of the largest threats to aquatic ecosystems and chlorophyll a measurements are relevant indicators of trophic state and algal abundance. Many studies have modeled chlorophyll a in rivers but model development and testing has largely occurred at individual sites which hampers creating generalized models capable of making broad-scale...
Marginal value analysis reveals shifting importance of migration habitat for waterfowl under a changing climate
Ryan C. Burner, Benjamin Donald Golas, Kevin J. Aagaard, Eric V. Lonsdorf, Wayne E. Thogmartin
2023, Ecology and Evolution (13)
Migratory waterfowl are an important resource for consumptive and non-consumptive users alike and provide tremendous economic value in North America. These birds rely on a complex matrix of public and private land for forage and roosting during migration and wintering periods, and substantial conservation...
Effects of landcover on mesocarnivore density and detection rate along an urban to rural gradient
Leah McTigue, Brett Alexander DeGregorio
2023, Global Ecology and Conservation (48)
Human development has major implications for wildlife populations. Urban-exploiter species can benefit from human subsidized resources, whereas urban-avoider species can vanish from wildlife communities in highly developed areas. Therefore, understanding how the density of different species varies in response to landcover changes associated with human development can provide important insight...
Shifted sediment-transport regimes by climate change and amplified hydrological variability in cryosphere-fed rivers
Tinghu Zhang, Dongfeng Li, Amy E. East, Albert J. Kettner, James L. Best, Jinren Ni, Xixi Lu
2023, Science Advances (9)
Climate change affects cryosphere-fed rivers and alters seasonal sediment dynamics, affecting cyclical fluvial material supply and year-round water-food-energy provisions to downstream communities. Here, we demonstrate seasonal sediment-transport regime shifts from the 1960s to 2000s in four cryosphere-fed rivers characterized by glacial, nival, pluvial, and mixed regimes, respectively. Spring sees a...

Reach-scale associations between introduced Brook Trout and juvenile and stream-resident Bull Trout in Idaho
Nicholas S. Voss, Brett J. Bowersox, Michael C. Quist
2023, Transactions of American Fisheries Society (152) 835-848
ObjectiveNative Bull Trout Salvelinus confluentus populations can be influenced by a variety of stressors operating at multiple spatial scales, making the relative importance of biotic versus abiotic controls difficult to discern at small scales where monitoring and management typically occur. Nonnative Brook Trout S. fontinalis were widely introduced throughout western North...

Alexander Koeberle, Webster Pearsall, Brad Hammers, Daniel Mulhall, James E. McKenna Jr., Marc Chalupnicki, Suresh Andrew Sethi
2023, Scientific Reports (13)
Estimates of juvenile survival are critical for informing population dynamics and the ecology of fish, yet these demographic parameters are difficult to measure. Here, we demonstrate that advances in animal tracking technology provide opportunities to evaluate survival of juvenile tagged fish. We implemented a whole-lake telemetry array in conjunction with...

Developing a stochastic hydrological model for informing lake water level drawdown management
Xinchen He, Konstantinos Andreadisa, Allison H. Roy, Abhiskek Kumar, Caitlyn Butler
2023, Journal of Environmental Management (345)
Winter drawdown (WD) is a common lake management tool for multiple purposes such as flood control, aquatic vegetation reduction, and lake infrastructure maintenance. To minimize adverse impacts to a lake’s ecosystem, regulatory agencies may provide managers with general guidelines for drawdown and refill timing, drawdown magnitude, and outflow limitations. However,...
Geophysical logging For hydrogeology
John Williams, Frederick L. Paillet
2023, Book
Geophysical logging is the measurement and analysis of electrical, acoustic, nuclear, and other physical properties in a borehole using wireline or direct push technology. Geophysical logging is one of the primary methods of collecting subsurface information for hydrogeologic investigations. Groundwater scientists and engineers should have a basic understanding of borehole geophysics...
