Rachel Cook

Senior Research Scientist - Large Ungulate Ecology
Location: Independent – La Grande, OR

Background

Dr. Cook is a large ungulate ecologist whose primary research interests are linking plant communities and ungulate foraging responses to individual and population performance. These linkages provide the mechanism by which to link habitat conditions, and habitat change, to the performance of ungulate populations. Ungulate species of past and current research primarily include Rocky Mountain and Roosevelt elk, Shiras moose, mule deer and, in Canada, woodland caribou. Dr. Cook worked to develop strategies that integrate findings from captive-animal research of physiology, nutrition, and bioenergetics with wild-animal field research in ways that capitalize on the strengths of both. Captive studies involved the largest herd of tame elk in the world in the 1990s and 2000s and, more recently, tame caribou that were used in British Columbia and Ontario. These studies were combined with wild-animal studies across most of the western states (elk) and in British Columbia, the Northwest Territories, and Ontario (caribou). To date, Dr. Cook has collected body condition, lactation and pregnancy data on >5500 wild ungulates and recorded >3 million bites (of vegetation) from tame elk, mule deer, and caribou.
