Kangaroo Rats (Dipodomys) are small
long-lived graniverous
nocturnal burrow-dwelling rodents of North American arid zones, subject
to substantial risk
of predation and of food being expropriated by other
seed-eating animals. Some issues of interest include their foraging
and food caching decisions; how they modulate their exposure to
predation
risk; why they exhibit unusually slight sex differences in behaviour
and life history; and the sources and functional significance of
behavioural differences between individuals.
Most of this research on Kangaroo Rats is done at the
Philip L. Boyd
Deep Canyon Desert Research Center in southern California.
