Climbing Behaviour in Three African Rodent Species

Abstract

The climbing ability and propensity of Thallomys paedidcus, Praomys natalensis and Saccostomus campestrls were studied in the laboratory. Thallomys was morphologically and psychologically best adapted to arboreal life, although Praomys had the highest climbing frequency, largely attributable to a greater exploratory tendency. All three species made use of the tail in a prehensile manner, and it was also used as a balancing organ by Thallomys and Praomys. These two species, but more noticeably Thallomys, made use of semi-opposable digits on the hind-feet whilst climbing. Only Thallomys scent-marked branches.
