Escherichia coli monitoring and assessment in 2022 and 2023 after beach restoration at Lake St. Clair Metropark Beach, Macomb County, Michigan Escherichia coli monitoring and assessment in 2022 and 2023 after beach restoration at Lake St. Clair Metropark Beach, Macomb County, Michigan
Lake St. Clair Metropark Beach in Michigan has a history of closures because of elevated Escherichia coli (E. coli) concentrations in its recreational waters. To reduce closures, restoration projects were implemented in 2021 to deter waterfowl from congregating on the beach. In this study, the U.S. Geological Survey, in cooperation with the Michigan Department of the Environment, Great...

Resource selection for an endangered flying squirrel, Glaucomys sabrinus coloratus, in a montane sky-island system Resource selection for an endangered flying squirrel, Glaucomys sabrinus coloratus, in a montane sky-island system
Geographically isolated endemic species and their habitats in montane systems face stressors of rapid climate change as well as legacy and contemporary land use change. In the case of endangered species in fragmented terrestrial montane habitats, effectively sky-islands, insight into habitat use and resource selection is vital for effective conservation measures. We created a resource...

Pre-restoration sediment budget of a tidally restricted estuary reveals potential for landward transport Pre-restoration sediment budget of a tidally restricted estuary reveals potential for landward transport
Unnatural tidal restrictions are common features in estuaries, often arising from agricultural practices, road construction, or drainage activities. Restrictions tend to attenuate tides landward of the structure but can induce more complex effects in the seaward direction, including modification of natural geomorphic processes. The Herring River Estuary is the site of the largest salt...

Incorporating data sets with multiple sources of uncertainty in integrated species distribution models Incorporating data sets with multiple sources of uncertainty in integrated species distribution models
Data integration methods aim to improve species distribution estimates by incorporating multiple sources of uncertainty across datasets. Two major sources of uncertainty are: (1) variation in sampling effort across space and within datasets, and (2) variation in reliability associated with data collection protocols or timing among datasets. Our goal was to evaluate how different...

Suitability of ground-motion models for seismic hazard assessment in Puerto Rico and the U.S. Virgin Islands Suitability of ground-motion models for seismic hazard assessment in Puerto Rico and the U.S. Virgin Islands
We perform linear mixed-effects analyses with a ground-motion dataset to evaluate how well ground-motion models (GMMs) fit active crustal, subduction interface, and subduction intraslab earthquakes in Puerto Rico and the US Virgin Islands. Most of the GMMs reproduce the spatial variation in peak ground motions with earthquake magnitude and rupture distance but predict ground motions 0.3...

Factors affecting the spatial distribution of Niangua darters Etheostoma nianguae in streams of the Osage River basin, Missouri, USA Factors affecting the spatial distribution of Niangua darters Etheostoma nianguae in streams of the Osage River basin, Missouri, USA
Aquatic ecosystems are rapidly changing, posing challenges for the conservation of threatened and endangered species, such as the Niangua darter Etheostoma nianguae, and highlighting the need to evaluate habitat use at multiple scales. The Niangua darter is a small benthic fish endemic to north-flowing streams of the Osage River basin in south-central Missouri, USA, and is federally...

Estimating GPS-based social aggregation metrics using collar data Estimating GPS-based social aggregation metrics using collar data
Understanding social aggregation patterns in ungulate herds is essential for gaining behavioral insights, optimizing resource use, reducing human-wildlife conflict, and managing disease risk. As chronic wasting disease is the preeminent disease-related threat to cervid populations in North America, knowledge of contact between individuals and spatiotemporal patterns of aggregation...

Semantic segmentation of light-toned veins in multimodal ChemCam data Semantic segmentation of light-toned veins in multimodal ChemCam data
Since the Mars Science Laboratory landed in 2012, the ChemCam instrument aboard the rover has collected in-situ laser-induced breakdown spectroscopy (LIBS) data and context images along more than 35 km of the Gale Crater traverse, providing valuable observations including diagenetic features such as light-toned veins. These veins are of particular scientific interest because they are...

Describing the seasonal abundance and growth rates of larval fishes across productivity gradients in Lake Huron in 2017 Describing the seasonal abundance and growth rates of larval fishes across productivity gradients in Lake Huron in 2017
Several of the Laurentian Great Lakes, including Lake Huron, have undergone oligotrophication in the past decades and prey fish biomass has concomitantly declined. One potential mechanism to explain declines in prey fish is slower growth and lower survival at the larval stage. To determine whether reduced productivity affects the growth of larval fish, we sampled larval fishes and their

From model to action: Identifying the gaps in coastal marsh models for decision making From model to action: Identifying the gaps in coastal marsh models for decision making
Coastal salt marsh modeling projects are designed to answer questions about where salt marshes may migrate, how they can migrate, and how they will be impacted by changing water levels. While this information is vital for climate-resilient marsh conservation, translating these findings into actionable results remains a challenge. The authors examined the actionability of marsh modeling...
