Abstract

Abstract: Male takeover is a form of male reproductive competition in non-human primates. In this study, we described two cases of male takeover in François’langurs (Trachypithecus francoisi) in Mayanghe National Nature Reserve, Guizhou, China. In case 1, a new adult male successfully invaded a group, while the resident male wandered in the periphery of the home range. One male infant was killed by the immigrant male after the male takeover. The remaining two infants and one male juvenile were no longer observed, and the remaining two male juveniles stayed with the resident male. Staying with the resident male may be a strategy for male juveniles to avoid male infanticide. All the females stayed in the group with the immigrant male. In case 2, a new adult male successfully immigrated into a group, ousting the resident male after an intense chase. Male takeover resulted in group division. Females without infants and one female juvenile stayed with the immigrant male. Females with infants, subadult and juvenile males dispersed with the resident male. After the takeover event, the invaded male did not attack the female juvenile in the group. The trade-offs between the risk of infanticide, reproductive benefit, and competition risk may determine the behavioral strategies of François’langurs.

Key words: François’langur (Trachypithecus francoisi), Male takeover, Infanticide, Karst habitat
