Cooperative Research Units

Established in 1935 at Iowa State University, our mission is our hallmark: work with University students to develop the conservation workforce, help decision-makers make complex conservation decisions, and to provide technical assistance between natural resource agencies and universities. We support 43 units located in 41 States, at 44 host universities. Our Program Office is in Reston, Virginia.

Fomites could determine severity of SARS-CoV-2 outbreaks in low-density white-tailed deer (Odocoileus virginianus) populations Fomites could determine severity of SARS-CoV-2 outbreaks in low-density white-tailed deer (Odocoileus virginianus) populations

The establishment of a reservoir species for zoonotic diseases is concerning for both animal and human health. Severe acute respiratory syndrome coronavirus (SARS-CoV)-2, the coronavirus responsible for the COVID-19 pandemic, has been detected in white-tailed deer (Odocoileus virginianus) in the United States. Since its initial detection, various studies have documented circulation and...

On the importance and practical conservation of nongame fishes. On the importance and practical conservation of nongame fishes.

Fisheries management has historically focused conservation efforts on game or sport species. However, most species are nongame—those not traditionally captured for sport or harvest in countries where recreational fisheries predominate. Greater conservation of nongame species could help ensure that population declines do not go unnoticed. Unfortunately, fisheries managers already manage...

Coexistence beyond disciplinary silos: Five dimensions of analysis for more convivial human-predator interactions Coexistence beyond disciplinary silos: Five dimensions of analysis for more convivial human-predator interactions

Understanding human-predator interactions has been a central goal of conservation for decades, yet many previous efforts have approached this challenge from disciplinary perspectives focused on single case studies. There is a need for more transdisciplinary and multi-sited research to enrich our understandings of the complexity of human-nonhuman interactions and to design ways to make...

Powering Progress: How Science Can Fuel the Energy Resources Life Cycle

Energy is essential to modern life, and accessing it involves a complex lifecycle, from resource discovery to extraction, use, and eventual remediation and reclamation. The USGS Ecosystems Mission Area supports this process by conducting research and providing scientific insights to guide decision-making at each stage. By collaborating with resource management agencies and stakeholders, we analyze...
