Aggression and dominance in tree shrews (Tupaia belangeri)
Tree shrews live solitary and defend their territories against intruding conspecifics of the same sex. Under laboratory conditions, housing of two males in one cage results in a stable dominance hierarchy1. The agonistic encounters between the two males are accompanied by intense reciprocal vocalisation and vary with their behaviour. The present study aimed to analyse the vocal repertoire of tree shrews during dyadic agonistic interactions, and to test whether call structure varied according to the dominance status or motivational state of the caller.
