2022, Biodiversity and Conservation (31) 353-377
Rapid recession of glaciers and snowfields is threatening the habitats of cold-water biodiversity worldwide. In many ice-sourced headwaters of western North America, stoneflies in the genus Lednia (Plecoptera: Nemouridae) are a prominent member of the invertebrate community. With a broad distribution in mountain streams and close ties to...

R. J. Strickman, S. M. Larson, H. Huang, Evangelos Kakouros, Mark C. Marvin-DiPasquale, C. P. J. Mitchell, R. B. Neumann
2022, Ecotoxicology and Environmental Safety (230)
Neurotoxic methylmercury (MeHg) accumulates in rice grain from paddy soil, where its concentration is controlled by microbial mercury methylation and demethylation. Both up- and down-regulation of methylation is known to occur in the presence of rice plants in comparison to non-vegetated paddy soils; the influence of rice plant presence/absence on...

Kellan R. Strauch, Philip J. Soenksen
2022, Scientific Investigations Report 2021-5102
The Niobrara River of northern Nebraska is a valuable water resource that sustains irrigated agriculture and recreation, as well as a diverse ecosystem. Large-quantity withdrawals from the source aquifer system have the potential to reduce the flow into the river and to adversely affect the free-flowing condition of the Niobrara...

Contributing areas to domestic wells in dipping sedimentary rocks under extreme recharge events
Claire R. Tiedeman, Allen M. Shapiro
2022, Groundwater (60) 460-476
We use particle tracking to determine contributing areas (CAs) to wells for transient flow models that simulate cyclic domestic pumping and extreme recharge events in a small synthetic watershed underlain by dipping sedimentary rocks. The CAs consist of strike-oriented bands at locations where the water table intersects high-hydraulic conductivity beds,...

2022, Marine Micropaleontology (171)
Calcareous nannofossil assemblages from middle to upper Eocene sediments of the western Tarim Basin indicate two important episodes of marine incursion into the basin. The first episode represents a period of shallowing upward in the Wulagen Formation, which is dated as...
Weakly supervised spatial deep learning for Earth image segmentation based on imperfect polyline labels
Zhe Jiang, Wenchong He, M. S. Kirby, Arpan Man Sainju, Shaowen Wang, Larry Stanislawski, Ethan J. Shavers, E. Lynn Usery
2022, ACM Transactions on Intelligent Systems and Technology (13)
In recent years, deep learning has achieved tremendous success in image segmentation for computer vision applications. The performance of these models heavily relies on the availability of large-scale high-quality training labels (e.g., PASCAL VOC 2012). Unfortunately, such large-scale high-quality training data are...

2022, Journal of Sustainable Water in the Built Environment (8) 1-10
Urban stormwater is an ongoing contributor to the degradation of the health of many watersheds and water bodies. In the United States, federal regulations (e.g., Clean Water Act) require monitoring and reporting of relevant water quality metrics in regulated waterbodies to ensure standards are being met, but decisions about how...
A web-based tool for assessing the condition of benthic diatom assemblages in streams and rivers of the conterminous United States
Daren M. Carlisle, Sarah A. Spaulding, Meredith Tyree, Nicholas O. Schulte, Sylvia S Lee, Richard M. Mitchell, Amina A. Pollard
2022, Ecological Indicators (135)
Benthic diatom assemblages are known to be indicative of water quality but have yet to be widely adopted in biological assessments in the United States due to several limitations. Our goal was to address some of these limitations by developing regional multi-metric indices (MMIs) that are robust to inter-laboratory taxonomic...

Matching of resource use and investment according to waterbody size in recreational fisheries
M.A. Kaemingk, R. Arlinghaus, M.H. Birdsong, C.J. Chizinski, R. Lyach, K.L. Wilson, Kevin L. Pope
2022, Fisheries Research (254)
The size of an ecosystem affects ecological interactions, but less is known about how ecosystem size may affect social interactions. We posit that ecosystem size could serve as a basis for understanding and contextualizing social interactions, connecting how ecosystem size influences natural resource investment decisions and the use of ecosystem services. We...

Often referred to as ecosystem engineers and sentinel species in marine ecosystems, these charismatic megafauna feed at a variety of trophic levels, affecting food web dynamics and cycling of chemicals and nutrients in...
Interagency Flood Risk Management (InFRM) watershed hydrology assessment for the Neches River basin. Appendix A: Statistical hydrology
David S. Wallace
2022, Report
Statistical analysis of the observational record from U.S. Geological Survey (USGS) streamgaging stations and other historical information provides an informative means of estimating flood flow frequency. Flood flow frequency is defined by values or quantiles of discharge for selected annual exceedance probabilities (AEPs) (England and others, 2018). The annual peak...

2022, Transactions of the American Fisheries Society (151) 81-99
Brook Trout Salvelinus fontinalis have faced significant declines throughout their native range and have been stocked in Midwestern waters since the late 1800s to offset such losses. Several studies have investigated the genetic effects of these stockings, but these efforts have been confined to relatively small spatial scales. In this study, we...
Response in the water level of Anvil Lake, Wisconsin, to changes in meteorological and climatic changes, Wisconsin
Dale M. Robertson
2022, Report
Anvil Lake, a relatively shallow seepage lake in northern Wisconsin, USA, has experienced dramatic changes in water level since elevation records began in 1938 in response to changes in meteorological and climatic conditions (Figure 1. Robertson et al., 2018). Anvil Lake’s water level record shows a pronounced 10–15-yr cycle, with...
Status and trends of the Lake Huron prey fish community, 1976-2020
Darryl W. Hondorp, Timothy P. O’Brien, Peter C. Esselman, Edward F. Roseman
2022, Report
The USGS Great Lakes Science Center (GLSC) has assessed annual changes in the offshore prey fish community of Lake Huron since 1973. Assessments are based on a bottom trawl survey conducted in October and an acoustics-midwater trawl survey conducted in September-October. In 2020, USGS-GLSC vessels were not permitted...
Agent-based modeling of movements and habitat selection by mid-continent mallards
Florian G. Weller, Elisabeth B. Webb, William S. Beatty, Sean Fogenburg, Dylan Kesler, Robert H. Blenk, John M. Eadie, Kevin Ringelman, Matt L. Miller
2022, Cooperator Science Series FWS/CSS-143-2022
We found that the absence of existing conservation measures would reduce wintering mallard population size by ~70-80%, underlining the importance of current wetland easements for waterfowl foraging. Under standard conditions, the partial active flooding of easements later in the season and the upgrading of unmanaged wetlands to managed status resulted...

David S. Wallace
2022, Report
RiverWare is a river system modeling tool developed by CADSWES (Center of Advanced Decision Support for Water and Environmental Systems) that allows the user to simulate complex reservoir operations and perform period-of-record analyses for different scenarios. For the InFRM hydrology studies, RiverWare is used to generate a homogeneous regulated POR...
Relative bias in catch among long-term fish monitoring surveys within the San Francisco Estuary
Brock Huntsman, Brian Mahardja, Samuel M. Bashevkin
2022, San Francisco Estuary and Watershed Science (20)
Fish monitoring gears rarely capture all available fish, an inherent bias in monitoring programs referred to as catchability. Catchability is a source of bias that can be affected by numerous aspects of gear deployment (e.g., deployment speed, mesh size, and avoidance behavior). Thus, care must be taken when multiple surveys—especially...
