Testing the interspecific body size principle in ungulates: the smaller they come, the harder they groom

Article Abstract:

A new study tests the body size principle of the programmed grooming model, which predicts that smaller-sized animals will groom to rid themselves of ticks more frequently than larger animals. The study of 25 species of bovids in a tick-free environment supports the theory.

Self grooming in impala mothers and lambs: testing the body size and tick challenge principles

Article Abstract:

The grooming rates of impala mothers and their lambs were analyzed to test the body size and tick challenge principles in animal grooming behavior. The grooming behaviors were observed in three different ages and study sites that varied in tick density. Results showed that the grooming rate of lambs was higher than their mothers, but gradually leveled off when the lambs were seven to eight months old. Moreover, results indicated that an intrinsic timing mechanism is responsible for the body-size and tick challenge grooming rates.
