The value of electronic tagging and tracking studies for understanding fish–hypoxia interactions The value of electronic tagging and tracking studies for understanding fish–hypoxia interactions
Objective Hypoxia (i.e., low dissolved oxygen availability) is a natural phenomenon but can also be induced by human activities (e.g., nutrient enrichment from runoff). Given that dissolved oxygen is essential for aquatic life, periods of hypoxia tend to have negative consequences (e.g., sublethal disturbances, mortality) for most fishes. Extensive laboratory research has documented...

Climate-adaptive urban planning: Quantitative assessment of drought impacts and practical strategies for climate-resilient urban green spaces Climate-adaptive urban planning: Quantitative assessment of drought impacts and practical strategies for climate-resilient urban green spaces
Urban green spaces (UGSs) are vital for enhancing a city’s resilience and livability; however, their functionality is increasingly jeopardized by drought, particularly in water-scarce regions. This study evaluates drought impact on UGSs in Metropolitan Adelaide, Australia, a representative semi-arid urban system, using satellite-derived Normalized Difference Vegetation Index (NDVI) time...

Estimating greater sage-grouse population sizes within the state of Oregon, USA 2017–2024 Estimating greater sage-grouse population sizes within the state of Oregon, USA 2017–2024
We fit an N-mixture model to lek (breeding area) count data to estimate annual population sizes of greater sage-grouse (Centrocercus urophasianus; sage-grouse) within the state of Oregon, USA between 2017–2024. Population estimates were delineated among 24 Priority Areas for Conservation (PACs) and considered additional sources of information including male-to-female sex ratios, lek...

Resources to inform the 2026 Colorado Climate Preparedness Roadmap: Compound hazards and associated public health implications Resources to inform the 2026 Colorado Climate Preparedness Roadmap: Compound hazards and associated public health implications
Changing environmental conditions are increasing the frequency and severity of extreme weather and environmental hazards, including heat waves, wildfires, drought, reduced water quality, and degraded air quality from ozone (O3) and fine particulate matter pollution (AghaKouchak et al., 2020; Bolinger et al., 2024; Colorado Health Institute, 2023a; Fann et al., 2015; IPCC, 2023a; Nagamoto...

Effects of rice idling on occupancy dynamics and survival of giant gartersnakes (Thamnophis gigas) in the Sacramento Valley, California, 2016–24 Effects of rice idling on occupancy dynamics and survival of giant gartersnakes (Thamnophis gigas) in the Sacramento Valley, California, 2016–24
The giant gartersnake (Thamnophis gigas) is a semi-aquatic species of snake endemic to marshes and sloughs in the Central Valley of California. Because the Central Valley has lost a substantial amount of wetland habitat, giant gartersnake populations are typically found in aquatic habitats associated with rice (Oryza sativa) agriculture. Therefore, changes to the amount and location of...

Global carbon investment in terrestrial biological nitrogen fixation Global carbon investment in terrestrial biological nitrogen fixation
Biological nitrogen (N) fixation (BNF) provides the N needed to produce proteins and other biological building blocks, helping feed humanity and mitigate climate change. Due to its high energetic cost compared to other forms of N acquisition, biotic investment in BNF indicates N limitation. Globally gridded BNF flux data provide an opportunity to determine the energetic investment in BNF...

Lead exposure of snakes near recreational and military shooting areas in a sagebrush steppe ecosystem Lead exposure of snakes near recreational and military shooting areas in a sagebrush steppe ecosystem
Lead exposure has been documented in a multitude of bird and mammal species but less frequently in reptiles. Of the studies that have evaluated lead concentrations in reptiles, few have focused on snakes. We analyzed lead concentrations in liver and two types of bone from 24 gophersnakes (Pituophis catenifer; Pc) and 12 Great Basin rattlesnakes (Crotalus oreganus lutosus; Col) found dead...

Integrating habitat suitability and climate constraints to predict nonnative fish invasion risk for U.S. streams and inland lakes Integrating habitat suitability and climate constraints to predict nonnative fish invasion risk for U.S. streams and inland lakes
Introduction: Nonnative fishes in streams and inland lakes can substantially alter aquatic ecosystems by degrading habitat conditions, competing with native species, and restructuring food webs. Identifying invasion hotspots can inform proactive management and prevention of nonnative species establishment. Methods: In this study, we identified streams and lakes across the conterminous...

Is "weediness" and "invasiveness" of weeds a function of the plant microbiome? Is "weediness" and "invasiveness" of weeds a function of the plant microbiome?
Over the past several decades, the extent to which microbes enhance plant development and health has become clearer; however, this has not been explored in terms of the aggressiveness and hardiness of weedy plants. In this review, we explore the hypothesis that many features of weeds and invasive plants are related to the activities of plant microbiomes. Microbes contribute to weed...

Northern bobwhites select for native grasses on working grazing land Northern bobwhites select for native grasses on working grazing land
Northern bobwhite (Colinus virginianus; bobwhite) populations have experienced an 85% decline across most of its range since the 1960s. The most drastic decreases have been in the southeastern United States where biologists attribute the decline to widespread habitat loss, including conversion of native grasslands to tall fescue (Lolium arundinaceum) and other exotic cool-season grass...

Cascading consequences and interventions for hazards after wildfire in northern California Cascading consequences and interventions for hazards after wildfire in northern California
This report documents the process and outcomes of a workshop convened by the U.S. Geological Survey in December 2024 to identify cascading postfire hazards and other effects stemming from the 2021 Dixie Fire in northern California and to explore potential intervention strategies. The Postfire Hazards and Consequences Workshop brought together stakeholders with expertise across...

Tracing mercury from land to river: Global sources, retention, and implications for sustainability Tracing mercury from land to river: Global sources, retention, and implications for sustainability
Mercury (Hg) pollution in river systems is a global sustainability challenge. Yet the transport, transformation, and retention of Hg within global rivers remain poorly quantified, particularly in regions with sparse observations such as Southeast Asia and Africa, hindering effective pollution mitigation and reinforcing geographic inequities in scientific knowledge and environmental...
