Thomas J. Williams, Greg S. Totzke
2024, Scientific Investigations Report 2024-5078
The Kansas River is an essential water resource that provides 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 water-treatment strategies to remove contaminants before distribution. Water District No. 1 of Johnson County,...
Quantitative support for the benefits of proactive management for wildlife disease control
Molly Bletz, Evan H. Campbell Grant, Graziella Vittoria DiRenzo
2024, Conservation Biology
Finding effective pathogen mitigation strategies is one of the biggest challenges humans face today. In the context of wildlife, emerging infectious diseases have repeatedly caused widespread host morbidity and population declines of numerous taxa. In areas yet unaffected by a pathogen, a proactive management approach has the potential to minimize...
Constraining mean landslide occurrence rates for non-temporal landslide inventories using high-resolution elevation data
Jacob Bryson Woodard, Sean Richard LaHusen, Benjamin B. Mirus, Katherine R. Barnhart
2024, Journal of Geophysical Research: Earth Surface (129)
Constraining landslide occurrence rates can help to generate landslide hazard models that predict the spatial and temporal occurrence of landslides. However, most landslide inventories do not include any temporal data due to the difficulties of dating landslide deposits. Here we introduce a method for estimating the mean...

Daniel Brothers, Brian Sherrod, Drake Moore Singleton, Jason Scott Padgett, Jenna C. Hill, Andrew C. Ritchie, Jared W. Kluesner, Peter Dartnell
2024, Geosphere
Ozette Lake is an ~100-m-deep coastal lake located along the outer coast of the Olympic Peninsula (Washington, USA); it is situated above the locked portion of the northern Cascadia megathrust but also relatively isolated from active crustal faults and intraslab earthquakes. Here we...
Acute toxicity of lampricides to non-target species of concern in the Lake Champlain watershed
Gary N. Neuderfer, Lance E. Durfey, Michael T. Calloway, Stephen J. Smith, Justin Schueller
2024, Journal of Great Lakes Research
Previous research evaluated the toxicity of the lampricide 4-nitro-3-(trifluoromethyl)phenol (TFM) and the combination of TFM with 1 % niclosamide (TFM:1%Nic) to multiple non-target species in the Laurentian Great Lakes. However, few toxicity studies have been conducted for species of concern in Lake Champlain (NY and VT). We conducted 12-hour flow-through toxicity...
Ecological function maintained despite mesomammal declines
Rebecca K. McKee, Paul J. Taillie, Kristen Hart, Christopher L. Lopez, Adam Sanjar, Robert A. McCleery
2024, Scientific Reports (14)
Mid-sized mammals (i.e., mesomammals) fulfill important ecological roles, serving as essential scavengers, predators, pollinators, and seed dispersers in the ecosystems they inhabit. Consequently, declines in mesomammal populations have the potential to alter ecological processes and fundamentally change ecosystems. However, ecosystems characterized by high functional redundancy, where multiple species can fulfil...
Subduction zone geometry modulates the megathrust earthquake cycle: Magnitude, recurrence, and variability
James Burkhardt Biemiller, Alice-Agnes Gabriel, Dave May, Lydia M. Staisch
2024, Journal of Geophysical Research: Solid Earth (129)
Megathrust geometric properties exhibit some of the strongest correlations with maximum earthquake magnitude in global surveys of large subduction zone earthquakes, but the mechanisms through which fault geometry influences subduction earthquake cycle dynamics remain unresolved. Here, we develop 39 models of sequences of earthquakes and aseismic slip (SEAS) on variably-dipping...

Caelan Simeone, John C. Hammond, Stacey A. Archfield, Dan Broman, Laura Condon, Hisham Eldardiry, Carolyn G. Olson, Jen Steyaert
2024, Geophysical Research Letters (51)
Hydrological drought is a pervasive and reoccurring challenge in managing water resources. Reservoirs are critical for lessening the impacts of drought on water available for many uses. We use a novel and generalized approach to identify periods of unusually low reservoir storage—via comparisons to operational rule curves and historical patterns—to...

Martin Albert Simonson, David Bunnell, Charles P. Madenjian, Kevin Keeler, Joseph Schmitt
2024, Journal of Great Lakes Research
The cisco Coregonus artedi is a coldwater fish that is distributed throughout much of Canada and the northern United States, including the Laurentian Great Lakes. Cisco historically supported large commercial fisheries in the Great Lakes during the late 1800s and early 1900s, but many populations declined and never recovered. Restoration efforts focusing...

2024, JGR Biogeosciences (129)
Decadal scale lake drying in interior Alaska results in lake margin colonization by willow shrub and graminoid vegetation, but the effects of these changes on plant production, biodiversity, soil properties, and soil microbial communities are not well known. We studied changes in soil organic carbon (SOC) and nitrogen (N) storage,...

Oronde Oliver Drakes, Diana Restrepo-Osorio, Kathryn Powlen, Megan Hines
2024, Water Resources Research (60)
Water insecurity poses a complex challenge for the western United States. Large populations are exposed and susceptible to physical and social factors that can leave them with precarious access to sufficient water supplies. Consideration of social issues by water managers can help ensure equitable supply. However, how...
