The collective application of shorebird tracking data to conservation The collective application of shorebird tracking data to conservation
Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence-based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership of scientists and practitioners called the...

The contribution of a surge event to infilling in a barrier-enclosed estuary: Insights from field observations The contribution of a surge event to infilling in a barrier-enclosed estuary: Insights from field observations
Many estuaries worldwide face increasing sediment loading caused by catchment land use change and intensification, creating subsequent adverse effects on estuarine ecosystems. Extreme weather events can disproportionately alter sediment pathways and loading. Although storm-driven sediment exchange has been widely examined at open coasts and inlets, key transport mechanisms within...

The damability function: A probabilistic approach to regional landslide dam susceptibility analysis applied to the Oregon Coast Range, USA The damability function: A probabilistic approach to regional landslide dam susceptibility analysis applied to the Oregon Coast Range, USA
Landslides can dam rivers and require rapid response to mitigate catastrophic outburst floods. Here, we present a workflow to map landslide dam formation susceptibility at a regional scale. We define a probabilistic function that combines river valley width and landslide volume to efficiently determine the likelihood of a landslide dam or “damability”. We combine damability values with...

The development of long-term mean annual total nitrogen and total phosphorus load models for Mississippi, U.S., using RSPARROW The development of long-term mean annual total nitrogen and total phosphorus load models for Mississippi, U.S., using RSPARROW
Water-quality degradation from nutrient pollution remains a major challenge for resource managers. Developing effective strategies requires tools to characterize nutrient sources and transport. This study used the RSPARROW framework to develop and assess new, smaller-scale models for Total Nitrogen (TN) and Total Phosphorus (TP) transport across Mississippi (MS). These state-level models...

The digital archivist: Automating legacy macroseismic data processing using large language models The digital archivist: Automating legacy macroseismic data processing using large language models
Macroseismic data are a key resource to investigate shaking and damage from preinstrumental and early instrumental eras. However, data are often stored as inconsistently formatted reports describing observed shaking and damage, making manually parsing and interpreting accounts labor‐intensive. We introduce a novel workflow using Google’s Gemini 2.5 Pro large language model (LLM) to...

The effect of solar energy development on plant diversity across spatial scales The effect of solar energy development on plant diversity across spatial scales
Utility-scale solar energy development is a novel and rapidly expanding land-use with largely unknown consequences for plant diversity. Construction disturbance and associated increases in environmental heterogeneity in solar facilities relative to undisturbed ecosystems can affect plant diversity at multiple spatial scales. We assessed the effects of modified construction methods...

The effects of scientific uncertainty and values trade-offs on flow management decisions for an endangered fish The effects of scientific uncertainty and values trade-offs on flow management decisions for an endangered fish
Consumptive use of freshwater is of concern in many estuarine ecosystems, and various frameworks have been used to prescribe environmental flows to benefit native species. However, few of these frameworks explicitly examine the potential trade-offs between socioeconomic and conservation-oriented values. This is exemplified in California, USA, where freshwater management has been an area...

The electric vehicle “EV”-crane—A next-generation system for fluvial sediment and water-quality sampling using an electric cart with integrated crane and accessories The electric vehicle “EV”-crane—A next-generation system for fluvial sediment and water-quality sampling using an electric cart with integrated crane and accessories
The U.S. Geological Survey (USGS), with support from the Federal Interagency Sedimentation Project (FISP), developed the electric vehicle (EV)-crane, a modified electric cart equipped with a rigid swivel-mounted crane and integrated accessory holders. The EV-crane was developed to improve the efficiency and safety of fluvial sediment and water-quality sampling from bridges. USGS field...

The functional effects of African lions on co-occurring carnivores differ across species pairs and with changes in resource availability and lion abundance The functional effects of African lions on co-occurring carnivores differ across species pairs and with changes in resource availability and lion abundance
Apex carnivores are known to regulate ecosystem structure and function, including via interactions with syntopic, competitively inferior carnivores. These effects may be dependent on relative carnivore density and resource availability or productivity. We investigated the functional effect of African lions as an apex carnivore on the presence of co-occurring large carnivore species...

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...

The Global Observation System for Mercury dataset for mercury stable isotope signatures in environmental media The Global Observation System for Mercury dataset for mercury stable isotope signatures in environmental media
The natural variability in the abundance ratios of stable isotopes of mercury (Hg), which collectively forms its isotopic composition, provides information on Hg sources and biogeochemical pathways. Modern mass spectrometry has allowed for measurement of Hg isotope ratios across atmospheric, aquatic, and terrestrial compartments, often at trace levels. Since realizing the utility of Hg...

The global proliferation of aquatic, benthic Microcoleus: Taxonomy, distribution, toxin production, ecology, and future directions The global proliferation of aquatic, benthic Microcoleus: Taxonomy, distribution, toxin production, ecology, and future directions
There have been sporadic reports of aquatic, benthic Microcoleus proliferations in freshwater rivers, lakes, and reservoirs for four decades, with reports increasing in frequency over the last twenty years, suggesting a possible rise in their global distribution, frequency, and intensity. Microcoleus can produce anatoxins which are neurotoxic, and ingestion of toxic mats has caused...
