3D viscoelastic models of slip-deficit rate along the Cascadia subduction zone 3D viscoelastic models of slip-deficit rate along the Cascadia subduction zone
Interseismic deformation in the Pacific Northwest is constrained by the horizontal crustal velocity field derived from the Global Positioning System (GPS) in addition to vertical rates derived from GPS, leveling, and tide gauge measurements. Such measurements were folded in to deformation models of fault slip rates as part of the 2023 National Seismic Hazard Model (NSHM) update. Here I...

Maintenance of genetic diversity despite population fluctuations in the lesser prairie-chicken (Tympanuchus pallidicinctus) Maintenance of genetic diversity despite population fluctuations in the lesser prairie-chicken (Tympanuchus pallidicinctus)
Assessments of genetic diversity, structure, history, and effective population size (N e) are critical for the conservation of imperiled populations. The lesser prairie-chicken (Tympanuchus pallidicinctus) has experienced declines due to habitat loss, degradation, and fragmentation in addition to substantial population fluctuations with unknown effects on genetic diversity. Our...

Bathymetric contour maps, surface area and capacity tables, and bathymetric change maps for selected water-supply lakes in Missouri, 2022–23 Bathymetric contour maps, surface area and capacity tables, and bathymetric change maps for selected water-supply lakes in Missouri, 2022–23
Bathymetric data were collected at 13 water-supply lakes around the periphery of Missouri by the U.S. Geological Survey in cooperation with the Missouri Department of Natural Resources and various local agencies, as part of a multiyear effort to establish or update the surface area and capacity tables for the surveyed lakes. Surveys were carried out during the months of April and May in...

Winter tick sharing between ungulates in the Greater Yellowstone Ecosystem and implications for apparent competition Winter tick sharing between ungulates in the Greater Yellowstone Ecosystem and implications for apparent competition
Host species heterogeneity can drive parasite dynamics through variation in host competency as well as host abundance. We explored how elk (Cervus canadensis) with apparent subclinical infestations of winter tick (Dermacentor albipictus) may be a cryptic reservoir and drive winter tick dynamics, impacting moose (Alces alces) populations. We found that winter tick infestation loads did...

Using hydrogeologic context and water budgets to evaluate the potential for groundwater contributions to contaminants in Lake Superior Using hydrogeologic context and water budgets to evaluate the potential for groundwater contributions to contaminants in Lake Superior
This study presents a synthesis of the hydrogeology in the U.S. Lake Superior watershed and the contribution of groundwater to the water budget of the U.S. Lake Superior basin. Much of the shoreline of Lake Superior in Minnesota and Michigan is composed of hydrogeologic units contributing very little direct groundwater discharge to the lake. Groundwater in watersheds adjacent to the lake...

Lake Superior fish community and fisheries, 2001–2022: An era of stability Lake Superior fish community and fisheries, 2001–2022: An era of stability
Lake Superior is the least anthropogenically impacted of the Laurentian Great Lakes ecosystems, yet dramatic changes to the fish community are evident. Previous published works chronicled those changes and the efforts to rehabilitate the fish community through the year 2000. Here, we review through the year 2022, where post-rehabilitation stability was driven by lean lake trout...

Effects of river floods and sedimentation on a naturally dynamic Great Lakes estuary Effects of river floods and sedimentation on a naturally dynamic Great Lakes estuary
Some of the most biologically diverse coastal wetlands and estuaries are found along the Great Lakes, but the spatial extent and timing of river-related inundation and sedimentation vary greatly among natural and altered systems. We used hydrologic data, geomorphic change detection, and satellite imagery to study inundation and sedimentation patterns in the naturally dynamic estuary of...

Dominant Dolichospermum and microcystin production in Detroit Lake (Oregon, USA) Dominant Dolichospermum and microcystin production in Detroit Lake (Oregon, USA)
The excessive growth of harmful cyanobacteria, including Dolichospermum (formerly known as Anabaena), in freshwater bodies has become a pressing global concern. However, detailed information about the role of Dolichospermum in shaping bloom dynamics and producing cyanotoxins is limited. In this study, a bloom event dominated by Dolichospermum spp. at Detroit Lake (Oregon, USA) was...

Metabolic interactions underpinning high methane fluxes across terrestrial freshwater wetlands Metabolic interactions underpinning high methane fluxes across terrestrial freshwater wetlands
Current estimates of wetland contributions to the global methane budget carry high uncertainty, particularly in accurately predicting emissions from high methane-emitting wetlands. Microorganisms drive methane cycling, but little is known about their conservation across wetlands. To address this, we integrate 16S rRNA amplicon datasets, metagenomes, metatranscriptomes, and annual methane...

Food web structure of the Lake Superior fish community in 2021–2022 Food web structure of the Lake Superior fish community in 2021–2022
The trophic linkages and ecological requirements of the Lake Superior fish community have not been assessed on a whole lake scale in over a decade. Here, we investigated the trophic dynamics across multiple species and habitat zones of Lake Superior. From April to October of 2021 and 2022, a total of five piscivore, four planktivore, and six benthivore species were collected by region...

Assessing the Feasibility of Reintroducing San Francisco Gartersnakes (Thamnophis sirtalis tetrataenia) to La Honda Creek Open Space Preserve, San Mateo County, California Assessing the Feasibility of Reintroducing San Francisco Gartersnakes (Thamnophis sirtalis tetrataenia) to La Honda Creek Open Space Preserve, San Mateo County, California
Reintroductions are used worldwide to increase the viability of species and restore native ecological communities. The success of reintroductions is usually judged by the establishment of self-sustaining populations, restoration of naturally occurring ecological communities, and the species resuming its ecological function. Recovery for the endangered San Francisco gartersnake (SFGS...

The relative influence of geographic and environmental factors on rare plant translocation outcomes The relative influence of geographic and environmental factors on rare plant translocation outcomes
Conservation translocations are an established method for reducing the extinction risk of plant species through intentional movement within or outside the indigenous range. Unsuitable environmental conditions at translocation recipient sites and a lack of understanding of species–environment relationships are often identified as critical barriers to translocation success. However...
