Abstract

There is a need to study male–male relationships since models on the evolution of social relationships among primates have mainly focused on females. In this study aspects of the social relationships among lion-tailed macaque males in differently structured social units have been studied. The units include three hete-rosexual groups with (i) one adult, one subadult, and eight juvenile males; (ii) two adult males, one of which was castrated and (iii) two adult males and a subadult male compared under two different conditions, viz. in a small indoor and a much larger outdoor enclosure. The studies used focal animal sampling and covered minimally three months each. In the first study, over 40% agonistic interactions occurred between adult and subadult males. The interactions with juvenile males were largely of affiliative nature. The castrated male received lower aggression than the normal subadult male. The males showed more aggressive behaviour in the outdoor than in the indoor enclosure. In the latter condition, however, the males showed more disturbed behaviour. Observations from field studies, earlier attempts at establishing captive all-male groups, and the present study point to a high degree of social intolerance among adult lion-tailed macaque males. Therefore, the establishment of all-male groups in the zoos does not appear to be possible. However, due to the fact that the males, especially the related males, show largely affiliative behaviours, it is possible to maintain all-male groups, preferably of individuals from the same groups, up to subadulthood.
