We hope you will enjoy learning about the variety of ecosystems and species we are studying throughout the United States. We are part of the Northwest Region of the USGS and our scientists work on diverse issues such as climate change, endangered species, wildlife health, invasive species, and much more.

USGS has many partnerships, both foreign and domestic, that enhance our science capabilities, provide needed support to others, and expand our ability to serve the global community.  One little-known partnership that serves both foreign and domestic needs is the USGS science support to the U.S. Department of Defense (DOD) - U.S. Northern Command (USNORTHCOM).

Offspring of grizzly bear mothers with a history of human-bear conflicts are more likely to be involved in human-bear conflicts than offspring of mothers without a history of human-bear conflicts, according to a new study

West Glacier, Mont. – Two rare alpine insects – native to the northern Rocky Mountains and dependent on cold waters of glacier and snowmelt-fed alpine streams – are imperiled due to climate warming induced glacier and snow loss according to a study by the U.S. Geological Survey and its partners.

Trade-offs and efficiencies in optimal budget-constrained multispecies corridor networks

Conservation biologists recognize that a system of isolated protected areas will be necessary but insufficient to meet biodiversity objectives. Current approaches to connecting core conservation areas through corridors consider optimal corridor placement based on a single optimization goal: commonly, maximizing the movement for a target species across a network of protected areas. We show that...

Vive la résistance: genome-wide selection against introduced alleles in invasive hybrid zones

Evolutionary and ecological consequences of hybridization between native and invasive species are notoriously complicated because patterns of selection acting on non-native alleles can vary throughout the genome and across environments. Rapid advances in genomics now make it feasible to assess locus-specific and genome-wide patterns of natural selection acting on invasive introgression within and...

Climate-induced glacier and snow loss imperils alpine stream insects

Climate warming is causing rapid loss of glaciers and snowpack in mountainous regions worldwide. These changes are predicted to negatively impact the habitats of many range-restricted species, particularly endemic, mountaintop species dependent on the unique thermal and hydrologic conditions found only in glacier-fed and snowmelt-driven alpine streams. Though progress has been made, existing...
