2023, Journal of Environmental Quality (52) 508-522
To better understand agricultural nutrient losses, we evaluated relationships between management (e.g., manure and tillage), soil health measurements, and resulting edge-of-field (EOF) surface water quality. This work was conducted before or early into conservation implementation at 14 Great Lakes Restoration Initiative EOF sites spanning...
Population connectivity of aquatic insects in a dam-regulated, desert river
Erin F. Abernethy, Jeffrey Muehlbauer, Theodore Kennedy, Katie E. Dziedzic, Holland Elder, Molly K. Burke, David A. Lytle
2023, River Research and Applications (39) 364-374
Humans have exaggerated natural habitat fragmentation, negatively impacting species dispersal and reducing population connectivity. Habitat fragmentation can be especially detrimental in freshwater populations, whose dispersal is already constrained by the river network structure. Aquatic insects, for instance, are generally limited to two primary modes...
Climate and landscape controls on old-growth western juniper demography in the northern Great Basin, USA
Rachel A. Loehman, Emily K. Heyerdahl, Gregory T. Pederson, David B. McWethy
2023, Ecosystems (26) 362-382
Western juniper (Juniperus occidentalis Hook.) woodlands have persisted for millennia in semiarid parts of the northern Great Basin, USA, providing critical habitat for plant and animal species. Historical records suggest that the establishment of western juniper is strongly associated with regional climatic variability. For example, the abundance of western juniper pollen...

Using physiological conditions to assess current and future habitat use of a Subarctic frog
T. Hastings, Blake R. Hossack, L. Fishback, J. M. Davenport
2023, Integrative Zoology (18) 2-14
Species with especially close dependence on the environment to meet physiological requirements, such as ectotherms, are highly susceptible to the impacts of climate change. Climate change is occurring rapidly in the Subarctic and Arctic, but there is limited knowledge on ectotherm physiology in these landscapes. We...
Estimating the aboveground biomass and carbon stocks of tall shrubs in a prerestoration degraded salt marsh
Jacqualyn Fouse, Meagan J. Eagle, Kevin D. Kroeger, Timothy P. Smith
2023, Restoration Ecology (31)
Wetlands play a vital role in Earth's carbon cycle and provide important ecosystem services. Their ability to perform their roles can be compromised by human activities that destroy or impair their functioning. The restoration of degraded wetlands may allow carbon cycle functioning, as well as other...
Using genetic data to advance stream fish reintroduction science: A case study in brook trout
Shannon L. White, Thomas C Johnson, Jacob M Rash, Barbara A. Lubinski, David C. Kazyak
2023, Restoration Ecology (31)
Widespread extirpation of native fish populations has led to a rise in species reintroduction efforts worldwide. Most efforts have relied on demographic data alone to guide project design and evaluate success. However, the genetic characteristics of many imperiled fish populations including low diversity, local adaptation, and hatchery introgression emphasize the...
Luminescence ages and new interpretations of the timing and deposition of Quaternary sediments at Natural Trap Cave, Wyoming
Shannon A. Mahan, John R. Wood, Dave M Lovelace, Juan Laden, Jenny McGuire, Julie Meachen
2023, Quaternary International (647-648) 22-35
Natural Trap Cave, located in the Big Horn Mountains of north-central Wyoming, has a history of trapping and preserving a range of North American fauna that plummeted into the deep vertical entrance. These animal remains were buried and preserved within sediments of the main chamber and, in turn, have...

2023, Concurrency and Computation: Practice and Experience (35)
This article discusses the design and implementation of the Hawai’i Groundwater Recharge Tool, an application for providing data and analyses of the impacts of land-cover modifications and changes in precipitation on groundwater-recharge rates for the island of O’ahu. This application uses simulation data based on a set of 29 land-cover types and 2 precipitation...
Winter habitat selection and efficacy of telemetry to aid Grass Carp removal efforts in a large reservoir
Tyler Michael Hessler, Duane Chapman, Craig P. Paukert, Jeff C. Jolley, Michael E. Byrne
2023, North American Journal of Fisheries Management (43) 189-202
Grass Carp Ctenopharyngodon idella were introduced in North America to control aquatic vegetation in small, closed systems. However, when they escape into larger systems in which they can reproduce, they have the potential to cause significant declines and alterations in aquatic vegetation communities. These alterations can in turn affect native species that...
Early Pliocene marine transgression into the lower Colorado River valley, southwestern USA, by re-flooding of a former tidal strait
Rebecca Dorsey, Juan Carlos Braga, Kevin Gardner, Kristin McDougall-Reid, Brennan O’Connell
2023, Book chapter, Straits and seaways: Controls, processes and implications in modern and ancient systems
Marine straits and seaways are known to host a wide range of sedimentary processes and products, but the role of marine connections in the development of large river systems remains little studied. This study explores a hypothesis that shallow-marine waters flooded the lower Colorado River valley at c. 5 Ma along a...
Gene flow influences the genomic architecture of local adaptation in six riverine fish species
Yue Shi, Kristen L. Bouska, Garrett J. McKinney, William Dokai, Andrew Bartels, Megan V. McPhee, Wesley Larson
2023, Molecular Ecology (32) 1549-1566
Understanding how gene flow influences adaptive divergence is important for predicting adaptive responses. Theoretical studies suggest that when gene flow is high, clustering of adaptive genes in fewer genomic regions would protect adaptive alleles from recombination and thus be selected for, but few studies have tested...

Derrick R. Vaughn, Anne M. Kellerman, Kimberly Wickland, Robert G. Striegl, David C. Podgorski, Jon R. Hawkings, Jaap Nienhuis, Mark Dornblaser, Edward G. Stets, Robert G. M. Spencer
2023, Biogeochemistry (164) 117-141
Landcover changes have altered the natural carbon cycle; however, most landcover studies focus on either forest conversion to agriculture or urban, rarely both. We present differences in dissolved organic carbon (DOC) concentrations and dissolved organic matter (DOM) molecular composition within Upper Mississippi River Basin low order...

Josey Lee Ridgway, Katelyn M. Lawson, Stephen August Shier, Robin D. Calfee, Duane Chapman
2023, North American Journal of Fisheries Management (43) 176-188
We assessed the effectiveness of herding techniques on adult Silver Carp Hypophthalmichthys molitrix in a tributary to the Missouri River. Sites (600 m) were contained using block nets and treated with one of five herding techniques: (1) a method commonly used by commercial fishers in the United States (commercial technique), (2) pulsed-DC electrofishing...

2023, Journal of Climate (36) 4375-4391
Some of the largest climatic changes in the Arctic have been observed in Alaska and the surrounding marginal seas. Near-surface air temperature (T2m), precipitation (P), snowfall, and sea ice changes have been previously documented, often in disparate studies. Here, we provide an updated, long-term trend analysis (1957–2021; n =...

Effect of wave skewness and asymmetry on the evolution of Fire Island, New York
Muhammed Parlak, Bilal Ayhan, John C. Warner, Tarandeep S. Kalra, Ilgar Safak
2022, Conference Paper
Bedload transport of sediment by waves and currents is one of the key physical processes that affect the evolution of coasts, nearshore areas, and the engineering practices there. Wave skewness and asymmetry, both of which increase as waves shoal, result in a net bedload sediment flux over a wave cycle....
