Lawrence Igl, Deborah A. Buhl, Max Post van der Burg, Douglas H. Johnson
2023, Global Ecology and Conservation (46) 13 pages
Recent declines of grassland bird populations in North America are linked to habitat loss and fragmentation associated with agricultural practices. One tool used to conserve soil, water and wildlife habitat on agricultural fields is the U.S. Department of Agriculture’s Conservation Reserve Program (CRP), the largest...
Native amphibian toxin reduces invasive crayfish feeding with potential benefits to stream biodiversity
Gary M. Bucciarelli, Sierra J. Smith, Justin J. Choe, Phoebe D. Shin, Robert N. Fisher, Lee B. Kats
2023, BMC Ecological Evolution (23)
BackgroundBiodiversity is generally reduced when non-native species invade an ecosystem. Invasive crayfish, Procambarus clarkii, populate California freshwater streams, and in the Santa Monica Mountains (Los Angeles, USA), their introduction has led to trophic cascades due to omnivorous feeding behavior and a rapid rate of population growth. The native California...
Approaches for assessing flows, concentrations, and loads of highway and urban runoff and receiving-stream stormwater in southern New England with the Stochastic Empirical Loading and Dilution Model (SELDM)
Gregory E. Granato, Alana B. Spaetzel, Lillian C. Jeznach
2023, Scientific Investigations Report 2023-5087
The Stochastic Empirical Loading and Dilution Model (SELDM) was designed to help quantify the risk of adverse effects of runoff on receiving waters, the potential need for mitigation measures, and the potential effectiveness of such management measures for reducing these risks. SELDM is calibrated using representative hydrological and water-quality input...

2023, Open-File Report 2023-1071
The population of southern sea otters (Enhydra lutris nereis) at San Nicolas Island, California, has been monitored annually since the translocation of 140 southern sea otters to the island was completed in 1990. Monitoring efforts have varied in frequency and type across years. In 2017, the U.S. Navy and the...
Transferring deep learning models for hydrographic feature extraction from IfSAR data in Alaska
Larry V. Stanislawski, Nattapon Jaroenchai, Shaowen Wang, Ethan J. Shavers, Alexander Duffy, Philip T. Thiem, Zhe Jiang, Adam Camerer
2023, Conference Paper
The National Hydrography Dataset (NHD) managed by the U.S. Geological Survey (USGS) is being updated with higher-quality feature representations through efforts that derive hydrography from 3DEP HR elevation datasets. Deriving hydrography from elevation through traditional flow routing and interactive methods is a complex, time-consuming process that must be tailored for...

Eric D. Anderson, Jennifer R. Erxleben, Sharon L. Qi, Adrian P. Monroe, Katharine G. Dahm
2023, Circular 1510
Executive SummaryThe U.S. Geological Survey carries out a wide variety of multidisciplinary science projects through the Bureau’s regions, mission areas, programs, and science centers. However, this structure can limit interactions among individual scientists, segregate data holdings, and make it difficult to apply holistic, interdisciplinary science. In addition, technological advances in...

Ashley B.C. Goode, Erin Rivenbark, Jessica A. Gilbert, Conor P. McGowan
2023, Decision Analysis (20) 311-325
Species status assessments are used to inform U.S. Fish and Wildlife Service (USFWS) decision making for Endangered Species Act (ESA) classification decisions, recovery planning, and more. The large number of species that require assessment and uncertainty in the data available impede the process of assigning and completing the assessments, which...

Pardus in the press: Drivers of leopard (Panthera pardus fusca) attack occurrence on humans in Nepal
Shashank Poudel, Joshua P. Twining, Richard C. Stedman, Shravan Kumar Ghimire, Angela K. Fuller
2023, People and Nature (5) 177-188
The negative impact of large carnivore presence in human-dominated landscapes manifests as livestock depredation and in extreme cases as attacks on humans. In the case of conflict with leopards in Nepal, attacks resulting in human fatality have become more frequent over time, thus creating an urgent socio-ecological and management...
a-positive: A robust estimator of the earthquake rate in incomplete or saturated catalogs
Nicholas van der Elst, Morgan T. Page
2023, JGR Solid Earth (128)
Detection thresholds in earthquake catalogs frequently change in time due to station coverage improvements and network saturation effects during active periods such as mainshock-aftershock cascades. This presents a challenge to seismicity-rate estimation; there is a tradeoff between using as low a minimum magnitude as possible to maximize...

Heikki Seppa, Marit-Solveig Seidenkrantz, Beth Elaine Caissie, Marc Macias Fauria
2023, Quaternary Science Reviews (317)
Polar bear (Ursus maritimus) is the apex predator of the Arctic, largely dependent on sea-ice. The expected disappearance of the ice cover of the Arctic seas by the mid 21st century is predicted to cause a dramatic decrease in the global range and population size of the species. To place...

Sara R. Warix, Alexis Navarre-Sitchler, Andrew H. Manning, Kamini Singha
2023, Water Resources Research (59)
The western U.S. is experiencing increasing rain to snow ratios due to climate change, and scientists are uncertain how changing recharge patterns will affect future groundwater-surface water connection. We examined how watershed topography and streambed hydraulic conductivity impact groundwater age and stream discharge at eight sites along a headwater stream...

In...
Prioritizing science efforts to inform decision making on public lands
Sarah K. Carter, Travis Haby, Jennifer K. Meineke, Alison C. Foster, Laine E. McCall, Leigh Espy, Megan A. Gilbert, Jeffrey E. Herrick, Karen Prentice
2023, Frontiers in Ecology and the Environment (21) 453-460
Public land management agencies in the US are committed to using science-informed decision making, but there has been little research on the types and topics of science that managers need most to inform their decisions. We used the National Environmental Policy Act to identify four types of science information needed...

Julia Guimond, Casu Demir, Barret L. Kurylyk, Michelle A. Walvoord, James W. McClelland, M. Bayani Cardenas
2023, Environmental Research Letters (18)
Groundwater discharge transports dissolved constituents to the ocean, affecting coastal carbon budgets and water quality. However, the magnitude and mechanisms of groundwater exchange along rapidly transitioning Arctic coastlines are largely unknown due to limited observations. Here, using first-of-its-kind coastal Arctic groundwater timeseries data, we evaluate the magnitude...

Devendra Dahal, Stephen P. Boyte, Michael Oimoen
2023, Rangeland Ecology and Management (90) 221-230
Expansion of exotic annual grass (EAG), such as cheatgrass (Bromus tectorum L.) and medusahead (Taeniatherum caput-medusae [L.] Nevski), could cause irreversible changes to arid and semiarid rangeland ecosystems in the western United States. The distribution and abundance of EAG species are highly affected by weather variables such as temperature and precipitation. The study's goal is to...
