Tracking Data for Blue-winged Teal (Anas discors)

Available here are tracking data of Blue-winged Teal, a duck species that breeds throughout much of North America but winters in Central and South America, thus providing a migratory link between the continents of North and South America. These data were collected to better understand the timing and patterns of migratory movements of Blue-winged Teals as part of a project on the dispersal of...

Status of American Eel populations in the Mohawk River Basin

Background: The waters of the Mohawk River basin are inhabited by one of the richest fish communities on the East Coast. The American Eel, Anguilla rostrata, is a unique member of this community, exhibiting a catadramous (maturing in fresh water and spawning in salt water) life history. Like many migratory fish, the American Eel has suffered a general decline across the East Coast largely...

Seabird Vulnerability Assessment for Renewable Energy Projects

The WERC seabird studies team has developed a new framework for quantifying seabird species vulnerability to wind infrastructure in the California Current region of the Pacific Outer Continental Shelf. This tool supports marine resource-use planning by identifying sites where seabirds are most vulnerable and predicts how different species may be affected by wind-energy infrastructure.

Post-fledging movement and habitat selection by mallards in the fall and their effect on spring recruitment

Considerable scientific research has been conducted in North America on nearly all aspects of the annual cycle of mallards, primarily focused on the breeding season. However, the period between when juveniles are capable of flight to their first southward migration remains a vastly understudied time for all waterfowl species. Beginning in 2018, a graduate student from South Dakota State...
