New Tibetan Macaque Research

This week has been a productive one for Tibetan macaque research. Alongside CWU and Anhui University student authors, primate behavior faculty members Dr. Lori Sheeran and Dr. Lixing Sun contributed to two new publications emerging from the Huangshan site at Valley of the Wild Monkeys in China. The first article documents interruption or harassment behavior exhibited by male adult and sub-adult Tibetan macaques during copulation events. This seasonal sexual interference may be a tactic to reduce the mating success of other males in the group, thereby helping to ensure (or increase the likelihood of) ones own reproductive success. Check out the paper in the journal Animals (doi: https://doi.org/10.3390/ani11030663). The second article, published in Frontiers in Ecology and Evolution, assesses the steepness of male and female dominance hierarchies through grooming patterns in two groups of Tibetan macaques. The authors suggest that the steepness of the respective dominance hierarchies plays an important role for middle-ranking females, in particular, to avoid reductions in their rank.
