Dean Biggins, PhD
Dr. Biggins is a scientist emeritus at the Fort Collins Science Center.
Dr. Biggins has been interested in grassland ecology since 1981. Within that broad topic his research has involved varied themes, including aspects of behavioral ecology, predator-prey relationships, and ecology of wildlife diseases. Most of his investigations have been motivated by their application to conservation and recovery of federally listed species. In that context, Dr. Biggins has worked at field study sites from Montana to Chihuahua, Mexico, as well as in Inner Mongolia and the Tibetan Plateau. Research has involved students at various universities (in CA, CO, ID, NM, MI, MO, TX, WY, France, and China). Taxa of interest have been carnivores (e.g., black-footed ferrets, Siberian polecats, badgers, weasels, coyotes, foxes), rodents, arthropods (fleas, ticks), and bacteria (Yersinia pestis). His present research emphasis is on ecology of plague, including its hosts and vectors, concentrating on maintenance of plague and its chronic effects on wildlife populations and ecosystems during inter-epizootic periods.
