Male mating patterns in wild multimale mountain gorilla groups
Article Abstract:
A significant number of mountain gorilla social units are multimale groups, although the species are classified as having a one-male mating system. A new study aims to examine male mating behavior and mating harassment from other males in relation to female reproductive states and male rank in two multimale gorilla groups in Rwanda. Results suggest that subordinate males can obtain mating opportunities in multimale groups, with dominant males being unwilling or unable to prevent mating.

Factor affecting mirror behaviour in western lowland gorillas, Gorilla gorilla
Article Abstract:
It is widely understood that it is difficult to demonstrate mirror self-recognition in gorillas. However, the failure of gorillas to show mirror self-recognition may be because direct eye contact is seen as a threat gesture in the species. A new study seeks to evaluate previous accounts of the apparent failure of gorillas to recognize themselves in mirrors. Details of the study are presented.

Do gorilla females join males to avoid infanticide? A quantitative model
Article Abstract:
A new study investigates the benefits for female gorillas of permanently associating with males. A recent hypothesis, that of protection from infanticidal nonfather males, is explored.
