Kelsey Shepherd is busy collecting samples and examining the impacts of site characteristics and landscape composition on bumble bee health and site use. This work will inform future habitat restoration work for rusty patched bumble bees in the Midwest.
Anna Tucker, PhD
Assistant Unit Leader - Iowa Cooperative Fish and Wildlife Research Unit
Dr. Tucker joined the Iowa Cooperative Fish and Wildlife Research Unit as Assistant Unit Leader in 2021. Prior to joining the Iowa Unit, Dr. Tucker received a M.S. degree from Virginia Commonwealth University, a Ph.D. from Auburn University, and was a postdoctoral researcher at the USGS Eastern Ecological Research Center (formerly Patuxent Wildlife Research Center). Her research themes include wildlife population ecology and demographics, population viability analysis, and wildlife-habitat associations, with an emphasis on the use of quantitative methods and hierarchical modeling to analyze demographic data. Most of her research has focused on migratory shorebirds, songbirds, and waterfowl, but she has also worked with other species of conservation concern including pollinators and herptofauna. Her work also involves using structured decision making to assist state and federal managers with decision making in the face of uncertainty. Dr. Tucker teaches a graduate-level class on Decision-support Modeling and has led workshops on Bayesian population analysis methods.

Sustaining Horseshoe Crabs and Supporting Migratory Shorebirds in the Delaware Bay
USGS is developing predictive models to inform sustainable harvest of horseshoe crabs ( Limulus polyphemus) in Delaware Bay to help managers make decisions to support needs of people and shorebirds including rufa red knot ( Calidris canutus rufa).
Informing Management of Waterfowl Harvest in a Changing Climate
The ability to effectively manage wildlife in North America is founded in an understanding of how human actions and the environment influence wildlife populations. Current management practices are informed by population monitoring data from the past to determine key ecological relationships and make predictions about future population status. In most cases, including the regulation of...

Dunlin shorebird in northern Alaska
Arctic-breeding shorebirds have experienced widespread population declines in recent decades. These declines are occurring even though Arctic nesting grounds are relatively undisturbed by human infrastructure and fragmentation, although future infrastructure expansion poses a threat to breeding birds.
