Use of Robotic DNA Samplers That Can Rapidly Detect Invasive Aquatic Species

USGS researchers and their collaborators demonstrated the efficacy of using robotic environmental DNA samplers for bio surveillance in freshwater systems, showing that samples collected, processed, and preserved by robotic sampler detect organism DNA in the environment at rates comparable to those collected traditionally by human technicians.

USGS Scientists are Busy as a Bee

Many bumble bee species have declined in recent decades due to changes in habitat, climate, and pressures from pathogens, pesticides and introduced species. The western bumble bee, once common throughout western North America, is a species of concern and is being considered for listing by the U.S. Fish and Wildlife Service under the Endangered Species Act.

A Unified Research Strategy for Disease Management

As wildlife diseases increase globally, an understanding of host-pathogen relationships can elucidate avenues for management and improve conservation efficacy. Amphibians are among the most threatened groups of wildlife, and disease is a major factor in global amphibian declines.

Large-scale Review of Amphibian Species and Community Response to Climate Change

Amphibian species and community richness has been declining in North America and climate change may play a role in these declines. Global climate change has led to a range shift of many wildlife species and thus understanding how these changes in species distribution can be used to predict amphibian community responses that may improve conservation efforts.

Long-term population dynamics and conservation risk of migratory bull trout in the upper Columbia River Basin

Conservation of migratory and sensitive fish like bull trout will require ecosystem level approaches that target stressors in headwater spawning and rearing habitats as well as critical habitats in rivers and lakes used during juvenile and adult life stages.

Annotated Bibliography: Research on Greater Sage-grouse since January 2015

The sheer number of scientific publications related to greater sage-grouse research can be a challenge for managers to navigate when updating plans for managing greater sage-grouse and sagebrush ecosystems. To assist in this process, the USGS reviewed and summarized scientific literature published since January 1, 2015.
