Generating a reference flow network with improved connectivity to support durable data integration and reproducibility in the coterminous US Generating a reference flow network with improved connectivity to support durable data integration and reproducibility in the coterminous US
This report presents a reference flow network for the conterminous United States that is built from the best available information from the U.S. Geological Survey, the National Oceanic and Atmospheric Administration National Weather Service, and the U.S. Environmental Protection Agency. The work is intended to support durable data integration and reproducibility. Originating from the...

User engagement testing with a pilot decision support tool aimed to support species managers User engagement testing with a pilot decision support tool aimed to support species managers
Species status assessments (SSAs) are required for endangered species by the U.S. Fish and Wildlife Service and focus on the resiliency, redundancy, and representation of endangered species. SSAs must include climate information, because climate is a factor that will impact species in the future. To aid in the inclusion of climate information, a decision support system (DSS) entitled...

People need freshwater biodiversity People need freshwater biodiversity
Freshwater biodiversity, from fish to frogs and microbes to macrophytes, provides a vast array of services to people. Mounting concerns focus on the accelerating pace of biodiversity loss and declining ecological function within freshwater ecosystems that continue to threaten these natural benefits. Here, we catalog nine fundamental ecosystem services that the biotic components of...

Permafrost microbial communities and functional genes are structured by latitudinal and soil geochemical gradients Permafrost microbial communities and functional genes are structured by latitudinal and soil geochemical gradients
Permafrost underlies approximately one quarter of Northern Hemisphere terrestrial surfaces and contains 25–50% of the global soil carbon (C) pool. Permafrost soils and the C stocks within are vulnerable to ongoing and future projected climate warming. The biogeography of microbial communities inhabiting permafrost has not been examined beyond a small number of sites focused on local...

High resolution lidar data shed light on inter-island translocation of endangered bird species in the Hawaiian Islands High resolution lidar data shed light on inter-island translocation of endangered bird species in the Hawaiian Islands
Translocation, often a management solution reserved for at-risk species, is a highly time-sensitive intervention in the face of a rapidly changing climate. The definition of abiotic and biotic habitat requirements is essential to the selection of appropriate release sites in novel environments. However, field-based approaches to gathering this information are often too time intensive...

Salinity and total dissolved solids measurements for natural waters: An overview and a new salinity method based on specific conductance and water type Salinity and total dissolved solids measurements for natural waters: An overview and a new salinity method based on specific conductance and water type
The total concentration of dissolved constituents in water is routinely quantified by measurements of salinity or total dissolved solids (TDS). However, salinity and TDS are operationally defined by their analytical methods and are not equivalent for most waters. Furthermore, multiple methods are available to determine salinity and TDS, and these methods have inherent differences. TDS is...

Contemporary distribution of non-native Chinook salmon (Oncorhynchus tshawytscha) in South America Contemporary distribution of non-native Chinook salmon (Oncorhynchus tshawytscha) in South America
Chinook salmon represent one of the most successful salmonid introductions in South America, and today multiple naturalized populations exist across Patagonia. Here, we present an updated regional distribution of Chinook salmon that includes new records of occurrences collected between 2006 and 2022. We found a significant range expansion in terms of occurrences for adult (18 new basins...

Bayesian forecasting of disease spread with little or no local data Bayesian forecasting of disease spread with little or no local data
Rapid and targeted management actions are a prerequisite to efficiently mitigate disease outbreaks. Targeted actions, however, require accurate spatial information on disease occurrence and spread. Frequently, targeted management actions are guided by non-statistical approaches that define the affected area by a pre-determined distance surrounding a small number of disease detections. As...

Potential effects of climate change on Emydoidea blandingii (Blanding’s turtle) Potential effects of climate change on Emydoidea blandingii (Blanding’s turtle)
Emydoidea blandingii (Holbrook, 1838; Blanding’s turtles) are a species of medium-sized, long-lived, semiaquatic, freshwater turtles with a wide distribution across the northern and eastern United States and southern Canada. They have an annual activity cycle consisting of late autumn and winter overwintering and spring emergence, spring movement and foraging, spring and summer nesting...

Rupture directivity of the 25 October 2022 Mw 5.1 Alum Rock earthquake Rupture directivity of the 25 October 2022 Mw 5.1 Alum Rock earthquake
The 25 October 2022 Mw 5.1 Alum Rock earthquake shows strong evidence for southeast rupture directivity along the central Calaveras fault (CCF), as indicated by observed ground motions and simulated kinematic ruptures. Peak ground accelerations (PGAs) and peak ground velocities (PGVs) are notably higher to the southeast, with an order of magnitude difference for stations at the same...

Nest attendance, incubation constancy, and onset of incubation in dabbling ducks Nest attendance, incubation constancy, and onset of incubation in dabbling ducks
In birds, parents must provide their eggs with a safe thermal environment suitable for embryonic development. Species with uniparental incubation must balance time spent incubating eggs with time spent away from the nest to satisfy self-maintenance needs. Patterns of nest attendance, therefore, influence embryonic development and the time it takes for eggs to hatch. We studied nest...

Use of environmental DNA to assess American Eel distribution, abundance, and barriers in a river-canal system Use of environmental DNA to assess American Eel distribution, abundance, and barriers in a river-canal system
Objective: The American Eel Anguilla rostrata historically was one of the most common fish species in Atlantic coast watersheds, but extensive dam construction and other factors caused a widespread population decline. One of the watersheds where American Eels have declined considerably is the Mohawk River in eastern and central New York. Recent attempts to characterize the distribution...
