Ungulate migration in a changing climate—An initial assessment of climate impacts, management priorities, and science needs

Executive SummaryMigratory behavior among ungulates in the Western United States occurs in response to changing forage quality and quantity, weather patterns, and predation risk. As snow melts and vegetation green-up begins in late spring and early summer, many migratory ungulates leave their winter range and move to higher elevation summer ranges to access high-quality forage and areas with veget

Protocols for collecting and processing macroinvertebrates from the benthos and water column in depressional wetlands

Freshwater aquatic macroinvertebrates are key links in food webs and nutrient cycles, and thus often serve as biological indicators of ecosystem health. Macroinvertebrate investigations in research and monitoring require consistent and reliable field and laboratory procedures. Comprehensive standard operating procedures for sampling macroinvertebrates from depressional wetlands, which can range fr

Hydraulics of freshwater mussel habitat in select reaches of the Big River, Missouri

The Big River is a tributary to the Meramec River in south-central Missouri. It drains an area that has been historically one of the largest lead producers in the world, and associated mine wastes have contaminated sediments in much of the river corridor. This study investigated hydraulic conditions in four study reaches to evaluate the potential contribution of physical habitat dynamics to mechan

Per-and Polyfluoroalkyl Substances (PFAS) Integrated Science Team

Increasing scientific and public awareness of the widespread distribution of per- and poly-fluoroalkyl substances (PFAS) in U.S. drinking-water supplies, aquatic and terrestrial ecosystems, wildlife, and humans has raised many public health and resource management questions that U.S. Geological Survey's (USGS) science can inform. The USGS Environmental Health Program's PFAS Integrated Science Team...

PFAS Transport, Exposure, and Effects

The team is determining the movement and behavior of per- and poly-fluoroalkyl substances (PFAS) from their sources in the environment, as they move through exposure pathways in ecosystems including watersheds and aquifers, their incorporation into food webs, and molecular to population scale effects on fish and wildlife. These studies are accomplished at a variety of spatial scales from regional...

Distribution of Highly Pathogenic Avian Influenza in North America, 2021/2022

The first 2021/2022 detection of Eurasian strain (EA) highly pathogenic avian influenza (HPAI) H5N1 in North America occurred in December 2021 in Newfoundland and Labrador, Canada. Subsequently, HPAI EA H5 and EA H5N1 viruses have been confirmed in wild birds, backyard flocks, commercial poultry facilities, and wild mammals in both Canada and the United States. This HPAI distribution map will be...
