Karyn Rode, Ph.D.
As a Research Wildlife Biologist, I conduct studies focused on the ecology, physiology, and behavior of large mammals to understand their response to environmental change, identify what environmental or ecological factors (e.g., prey availability, winter temperature, ice availability, etc.) most influence whether a population increases, decreases, or is stable, and to maintain positive wildlife-hu
I work with international and bilateral groups, such as the Polar Bear Range States and US-Russia Polar Bear Commission, DOI partners, including U.S. Fish and Wildlife Service, the Bureau of Land Management, and the U.S. National Park Service, Alaska Native co-management groups, and local and state governments to identify and address research needs for polar bears and walruses. My research focuses primarily on identifying biological and ecological indicators for monitoring large mammal populations and ecosystem change and determining mechanisms of population regulation in response to environmental change. I also study wildlife interactions with humans in areas of industry, via tourism and recreation, and in local communities to help minimize or avoid negative effects on wildlife and ensure human safety. Much of my work is centered on nutritional and physiological ecology and its effects on wildlife body condition, reproduction, and survival. Often, I work to develop new methods needed to address information needs. Although all research questions pertain to wild populations, I also regularly conduct studies with animals in zoos and other captive settings where more detailed study of animal physiology and development of new research techniques are possible.
