Understanding the population dynamics, predator/prey relationships and habitat ecology of terrestrial mammals, such as caribou and muskoxen, is critical for the management of these species and their habitats in Alaska.

Caribou in the Arctic
Research conducted by the USGS Alaska Science Center on terrestrial mammals is focused on informing Department of Interior management decisions across Alaska. Our work provides timely and highly relevant scientific information for management issues such as the response of caribou to a warming climate and human development, future possible changes in distribution and abundance, and the effects of changing habitats used for forage.
Population dynamics
Why do caribou populations fluctuate? Why do their migration patterns change year after year? How healthy is the herd? Working in collaboration with multiple partners in Alaska, the USGS is addressing these common questions for caribou populations in Alaska.

Response of caribou to industrial infrastructure
Are Arctic caribou habituated to energy development on the North Slope? Do caribou use habitats near and within the oilfields in northern Alaska? Read more here:
Forage and weather
Will caribou be impacted by changes in weather, insects and plant forages? Are their habitats changing?
