Developing Waterfowl Distribution and Abundance Models to Inform Avian Influenza Transmission Risk

USGS researchers are developing novel methods to improve our understanding of waterfowl distributions and abundance across the United States to inform a variety of ongoing disease studies. Understanding the distribution of wild waterfowl is a critical component to assessing avian influenza transmission risks across the landscape.

Genomics to Aid Conservation and restoration of the Yellow Lampmussel (Lampsilis cariosa) and Tidewater Mucket (Atlanticoncha ochracea)

Due to the rapid decline in abundance of Yellow Lampmussel ( Lampsilis cariosa) and Tidewater Mucket ( Atlanticoncha ochracea), USGS and partners at the U.S. Fish and Wildlife Service (USFWS) and Central Michigan University (CMU) are conducting an assessment of genetic diversity and population structure to inform appropriate recommendations for conservation and management of each species. These...

Advancing Risk Modeling for Highly Pathogenic Avian Influenza

Southeast Asia has long been the epicenter of AIV emergence. However, as demonstrated by H5NX, these viruses can quickly reach global spread and have significant impacts on poultry production and human health. Researchers at the USGS Eastern Ecological Science Center have two ongoing efforts funded by the National Science Foundation to help improve our understanding of AIV emergence, spread, and...

Population Monitoring and Removal Strategies for Blue Catfish (Ictalurus furcatus) in Chesapeake Bay

USGS is helping with the design of a population survey and developing mathematical models to assess potential activities to manage the population of invasive blue catfish ( Ictalurus furcatus) in the Chesapeake Bay. This research will help managers determine the cost and feasibility of approaches to control this invasive species.

Production, Behavior, and Survival of Juvenile Shad and River Herring

USGS is conducting research to better understand biology, behavior, and survival of juvenile fishes that travel between fresh and saltwater to complete their lifecycles. Migratory fishes as such as herring and shad are vital components in riverine and coastal ecosystems, transporting food and nutrients between fresh rivers and the ocean. They are also an important forage fish for predators in...

Developing a Process for Listing Injurious Wildlife Species

This project will develop a transparent process for prioritizing species for listing as injurious, likely to cause damage or harm, under the Lacey Act. Building upon previously developed "horizon scan" and "watchlist" products, this process will identify potentially invasive species that present the greatest risk to lands, waters, and other assets managed by the U.S. Department of the Interior.

Using Multiple Indicators to Assess Stream Condition in the Chesapeake Bay

USGS is working with federal, state and local partners to develop multiple assessments of stream and river conditions in non-tidal areas of the Chesapeake Bay watershed. These assessments will help managers preserve stream health and improve biological conditions in impaired streams as the human population and climate continue to change in this region.
