Intra- and interspecific variation in vigilance and foraging of two gerbillid rodents, Rhombomys opimus and Psammomys obesus: the effect of social environment

Intra- and interspecific variation in vigilance and foraging of two gerbillid rodents, Rhombomys opimus and Psammomys obesus: the effect of social environment

We studied time budgets in two closely related and ecologically similar gerbillids to test the effect of group size on vigilance and foraging in adult females. Psammonys obesus is strictly solitary, while Rhombomys opimus is mainly social.
