Cooperative Research Units

Established in 1935, our mission is our hallmark: meet the actionable science needs of our cooperators, provide technical assistance, and develop the future workforce through graduate education/mentoring. The Coop Units are located on 40 universities in 38 states. They are called Coop Units because each cooperator plays a role in the staffing, funding and directing the units.

Stoneflies in the genus Lednia (Plecoptera: Nemouridae): Sentinels of climate change impacts on mountain stream biodiversity

Rapid recession of glaciers and snowfields is threatening the habitats of cold-water biodiversity worldwide. In many ice-sourced headwaters of western North America, stoneflies in the genus Lednia (Plecoptera: Nemouridae) are a prominent member of the invertebrate community. With a broad distribution in mountain streams and close ties to declining glacier cover, Lednia has emerged as a sentinel of

Effects of environmental clutter on synthesized chiropteran echolocation signals in an anechoic chamber

Ultrasonic bat detectors are useful for research and monitoring purposes to assess occupancy and relative activity of bat communities. Environmental “clutter” such as tree boles and foliage can affect the recording quality and identification of bat echolocation calls collected using ultrasonic detectors. It can also affect the transmission of calls and recognition by bats when using acoustic lure

RAD adaptive management for transforming ecosystems

Intensifying global change is propelling many ecosystems toward irreversible transformations. Natural resource managers face the complex task of conserving these important resources under unprecedented conditions and expanding uncertainty. As once familiar ecological conditions disappear, traditional management approaches that assume the future will reflect the past are becoming increasingly unten

Decline of Beluga Whales in Cook Inlet, Alaska

In conjunction with the Cook Inlet PhotoID Project and federal agencies, the USGS Washington Cooperative Fish and Wildlife Research Unit is aiming to learn more about the fundamental factors that drive changes in beluga whale population dynamics, specifically what affects the rates at which individuals survive and reproduce.

The Role of Drought in Aquatic Systems

Drought is a natural disturbance of aquatic and terrestrial ecosystems in many regions worldwide and can be a major factor that impacts aquatic communities. Drought frequency and intensity are expected to increase due to climate change and can also be exacerbated by water withdrawals and other human impacts, such as agricultural and industrial uses.
