Welcome to the web page for the Wildlife Demographics lab at the University of Maine.  We are interested in the processes that determine how long animals live, how many offspring they produce, and how frequently they leave or join new populations.  These four demographic processes, survival, recruitment, immigration, and emigration, dictate how the abundance of wildlife changes through time and across space; the dynamics of populations.  Teaching and research within the lab centers on measuring wildlife demographic rates and evaluating population dynamics.  Importantly, we work to learn how factors in the environment, both "natural" and human-caused, influence these processes and cause wildlife populations to either grow or decline.

Please visit our research and teaching pages to learn more about specific lab activities, including research on a variety of wildlife including ruffed grouse, American woodcock, and bats.

The lab is housed in the Department of Wildlife, Fisheries, and Conservation Biology here at the University of Maine.  We are also supported through the Maine Agricultural and Forest Experiment Station, and the College of Natural Sciences, Forestry, and Agriculture

Inquiries about the lab should be sent to Dr. Erik Blomberg
