Principles of riverscape health Principles of riverscape health
Riverscapes are the integration of terrestrial and aquatic systems from headwaters to estuaries that provide habitat and ecosystem benefits when in good health. However, current riverscape degradation is pervasive, impairing the function and resulting benefits of these systems. Healthy riverscapes are adaptive and some can ‘heal’ after disturbance with minimal to no human assistance. As...

The breeding season and movement ecology of male white‐tailed deer in southwest Wisconsin The breeding season and movement ecology of male white‐tailed deer in southwest Wisconsin
White-tailed deer (Odocoileus virginianus; hereafter, deer) have been widely studied regarding their breeding ecology and responses to hunting pressures. However, variations in defining the breeding season—its duration and timing—across studies have created uncertainty about whether regional differences in deer breeding ecology stem from ecological factors or methodological...

2022 McKinney rain-on-wildfire event, dissolved oxygen sags, and a fish kill on the Klamath River, California 2022 McKinney rain-on-wildfire event, dissolved oxygen sags, and a fish kill on the Klamath River, California
The longitudinal propagation of water-quality and ecological impairments in rivers during and after wildfires remain poorly understood. In Northern California, the 2022 McKinney Fire burned 243 km2 of the Klamath National Forest, with 83% of the burned area classified as moderate to high severity. During the active wildfire, a high-intensity monsoonal rain event triggered sediment-laden...

Spatial and temporal variability of perfluoroalkyl and polyfluoroalkyl substances in major rivers of New Mexico, USA Spatial and temporal variability of perfluoroalkyl and polyfluoroalkyl substances in major rivers of New Mexico, USA
Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are ubiquitous in the environment, but sources that contribute to temporal and spatial variability in surface waters are not well defined. Many states are assessing PFAS in water resources, and insight from these statewide assessments can help guide future sampling efforts. A statewide assessment of 28 PFAS was conducted in New Mexico...

Unintended indirect effects limit elk productivity from supplemental feeding in the Greater Yellowstone Ecosystem Unintended indirect effects limit elk productivity from supplemental feeding in the Greater Yellowstone Ecosystem
The widespread practice of supplemental feeding, a bottom-up forcing of resource availability, is intended to improve wildlife population health and survival. However, supplemental feeding could trigger indirect effects by altering predation rates and disease dynamics. We investigated the effects of feeding on three key elk (Cervus canadensis) population productivity metrics (calf:cow...

Preparation and analysis methods for fish tissue collected from Lake Koocanusa, Montana Preparation and analysis methods for fish tissue collected from Lake Koocanusa, Montana
Lake Koocanusa, a reservoir, receives mine wastes from metallurgical coal mines in the Elk River Valley of British Columbia, Canada. Selenium and other elements discharged by the mines into the waters of the United States can pose unknown risks to aquatic life. The U.S. Geological Survey Wyoming-Montana Water Science Center can collaborate with Montana Fish, Wildlife and Parks and other...

Wake Atoll vessel movement biosecurity program efficacy Wake Atoll vessel movement biosecurity program efficacy
Executive Summary The purpose of this Wake Atoll Vessel Movement Biosecurity Program Efficacy document is to provide the United States Air Force (USAF) with an unbiased review of the current (2015; hereafter referred to as the 2015 Biosecurity Plan) biosecurity plan for the military base Wake Island Airfield (WIA) on Wake Atoll (hereafter Wake). Periodic reviews are an integral step for...

Widespread dispersal of a human commensal across the Pacific: Reconstructing the human-mediated invasion history of the house gecko (Hemidactylus frenatus) Widespread dispersal of a human commensal across the Pacific: Reconstructing the human-mediated invasion history of the house gecko (Hemidactylus frenatus)
The spread of human commensal species is intricately tied to human movements and historical events. Through waves of human migrations, colonization, trade routes, commercial activities, and war, humans have redistributed species from their native ranges to widely scattered areas across the Pacific. Deciphering the invasion history of recent human-mediated introductions is challenging due...

Revealing organofluorine contamination in effluents and surface waters with complementary analytical approaches: Fluorine-19 nuclear magnetic resonance spectroscopy (19F-NMR) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) Revealing organofluorine contamination in effluents and surface waters with complementary analytical approaches: Fluorine-19 nuclear magnetic resonance spectroscopy (19F-NMR) and liquid chromatography-tandem mass spectrometry (LC-MS/MS)
Fluorinated organic contaminants, including per- and polyfluoroalkyl substances (PFASs) and fluorinated pesticides and pharmaceuticals (FPPs), pose a persistent threat to environmental health. Widely used liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods fail to capture large fractions of total organofluorine in environmental samples, confounding the assessment of...

U.S. Geological Survey Groundwater Climate Response Network, 2024 U.S. Geological Survey Groundwater Climate Response Network, 2024
As of October 2024, the U.S. Geological Survey (USGS) operated 588 sites across the United States and its territories as part of the Groundwater Climate Response Network (CRN). The CRN is comprised of wells selected to monitor the effects of climate variability, such as droughts, on groundwater levels nationwide. The CRN includes nearly 500 locations with real-time data and more than 100...

Molecular evolution of TRPC4 regulatory sequences supports a role in mammalian thermoregulatory adaptation Molecular evolution of TRPC4 regulatory sequences supports a role in mammalian thermoregulatory adaptation
Background Proteins encoded by the canonical transient receptor potential (Trpc) gene family form transmembrane channels involved in diverse signal-transduction pathways. Trpc4 has been shown necessary for the induction of nonshivering thermogenesis (NST) in mice, a key component of which is thermogenic brown adipose tissue (BAT). In bats, Trpc4 exhibited diversifying selection within...

The structural and functional impacts of invasive Psidium cattleianum in forests on the Island of Hawai’i The structural and functional impacts of invasive Psidium cattleianum in forests on the Island of Hawai’i
During the past century, the proliferation of invasive species has contributed to loss of biodiversity and ecosystem degradation. In forests, invasive tree species can alter ecosystem function, but the underlying mechanisms of these changes are not fully understood. We use the ongoing invasion of P. cattleianum on the Island of Hawai’i to test the hypotheses that invasive structural...
