The geologic history of the Chehalis Forearc Basin, Washington State, USA The geologic history of the Chehalis Forearc Basin, Washington State, USA
The Chehalis basin is located between the Cascade arc and the Coast Range in southwest Washington State. It consists of sedimentary and volcanic rocks deposited throughout the Cenozoic and is underlain by the Siletzia terrane, a thick, large igneous province accreted in the Eocene. Here, we constrain evolution of the Chehalis basin depocenter using isochore maps derived from isostatic...

Long-term aridity shapes grassland drought resistance and modulates the roles of plant diversity and functional composition Long-term aridity shapes grassland drought resistance and modulates the roles of plant diversity and functional composition
Understanding the drivers of plant community stability is crucial for predicting ecosystem responses to extreme drought events. In grasslands, drought resistance supports the maintenance of key functions such as above-ground primary productivity, making the identification of resistance drivers essential to guide management under climate change. Proposed factors contributing to grassland...

Across-track tilt concept for sun glint mitigation in future Earth-observing missions Across-track tilt concept for sun glint mitigation in future Earth-observing missions
Sun glint is a major limitation for spaceborne optical remote sensing of aquatic environments, particularly in tropical and subtropical regions. By dominating the at-sensor radiance, sun glint complicates atmospheric correction and reduces the quality of aquatic reflectance products derived across Earth observation missions. This study presents a machine learning framework to quantify...

Restoration is a partial but not complete solution for long-term declines in oyster populations—A case history from the northeastern Gulf of America Restoration is a partial but not complete solution for long-term declines in oyster populations—A case history from the northeastern Gulf of America
Objective We sought to evaluate whether oyster reef restoration is associated with sustained increases in intertidal eastern oyster Crassostrea virginica density in Suwannee Sound, Florida, and to examine how commercial fishing activity and freshwater discharge may modify those patterns.Methods We monitored intertidal oyster reefs for 14 years, including 9 years prior to large-scale...

Ecogeomorphologic response of a tidally restricted salt marsh to tidal restoration and sea-level rise Ecogeomorphologic response of a tidally restricted salt marsh to tidal restoration and sea-level rise
Diked marshes with decades of restricted tidal flow exhibit fundamentally altered hydrologic and ecologic dynamics that result in limited vertical accretion, land subsidence, and underdeveloped tidal channels. These changes complicate marsh restoration efforts and constrain the marsh's ability to build elevation in response to future sea levels. In this study, we developed an integrated

Fipronil baits as emerging tools for flea control and plague mitigation: Experiments with cricetid mice on prairie dog colonies Fipronil baits as emerging tools for flea control and plague mitigation: Experiments with cricetid mice on prairie dog colonies
Plague is a zoonotic disease of mammalian hosts and flea vectors. Wildlife biologists most commonly mitigate plague by controlling flea populations. We evaluated the efficacy of edible baits for systemic flea control with two cricetid species on colonies of black-tailed prairie dogs (Cynomys ludovicianus): the western deer mouse (Peromyscus sonoriensis) and the northern grasshopper mouse

Lunar-VISE landing site selection and characterization at Mons Gruithuisen Gamma Lunar-VISE landing site selection and characterization at Mons Gruithuisen Gamma
The Lunar Vulkan Imaging and Spectroscopy Explorer (Lunar-VISE) was selected for a Commercial Lunar Payload Services (CLPS) delivery to the Gruithuisen domes region of the Moon as part of NASA’s Payloads and Research Investigation on the Surface of the Moon (PRISM) program. The Gruithuisen domes are chemically and morphologically distinct from their surroundings with a thorium-rich...

Toxoplasma gondii: Challenges and perspectives in interpreting longitudinal seroprevalence data for a chronic parasitic infection Toxoplasma gondii: Challenges and perspectives in interpreting longitudinal seroprevalence data for a chronic parasitic infection
Toxoplasma gondii—the causative agent of toxoplasmosis—is a zoonotic pathogen of warm-blooded hosts. Infection causes mild-to-severe symptoms, including lethargy, fever, muscle pain, abortion, ocular disease, and encephalitis. Toxoplasma affects many vertebrate species, although felids are the only known definitive hosts. Seroprevalence in wildlife is often assessed using cross-sectional...

A cross-site comparison of ecosystem- and plot-scale methane fluxes across multiple sites A cross-site comparison of ecosystem- and plot-scale methane fluxes across multiple sites
Wetland and upland ecosystems play significant but opposing roles in the global methane (CH4) budget, acting as natural sources and sinks, respectively. Two of the most common approaches for measuring CH4 fluxes (FCH4) are chambers, which measure fluxes at fine spatial scales (ca. 1 m2), and eddy covariance (EC) towers, which integrate fluxes across larger footprints (ca. 100–10 000 m2)...

Conflicts and collisions with an endangered carnivore: Landscape drivers and spatial risk pattern Conflicts and collisions with an endangered carnivore: Landscape drivers and spatial risk pattern
Human–wildlife conflicts and anthropogenic mortality are expected to increase with the continuous encroachment on natural habitats within and around protected areas, yet the processes governing these risks remain poorly understood. We investigated the spatiotemporal dynamics and drivers of two distinct processes involving the endangered Florida panther (Puma concolor coryi; hereafter...

Non-destructive sampling of larval amphibians shows tail tissues reflect whole-body methylmercury concentrations and trophic-related differences in bioaccumulation Non-destructive sampling of larval amphibians shows tail tissues reflect whole-body methylmercury concentrations and trophic-related differences in bioaccumulation
Mercury (Hg), and specifically methylmercury (MeHg), is a contaminant of global concern to humans and wildlife, but there is still limited understanding of its effects on many taxa. Amphibians are closely associated with water, where Hg is converted to MeHg, and high concentrations of MeHg can reduce survival of amphibians in the wild. However, limited non-lethal proxies exist for...

Weathering the ride: Associations of heat, smoke, precipitation, and ozone with bus ridership in Colorado Weathering the ride: Associations of heat, smoke, precipitation, and ozone with bus ridership in Colorado
Weather and climate variability increasingly shape urban travel behavior, yet the short-term temporal dynamics and contextual modifiers of weather-transit relationships remain poorly understood. We analyzed system-wide hourly bus ridership in the Denver metropolitan area from June 2022 through September 2023 using fixed-effects negative binomial distributed lag nonlinear models with lags...
