Mountain gorilla groups are friendly to familiar neighbours – provided they stay out of “core” parts of their territory – new research shows.
Gorillas live in tight-knit groups, foraging, resting and sleeping together around a “core home range” and a wider “peripheral” range.
These groups sometimes split permanently, separating gorillas that may have lived together for years and may be closely related.
The new study – by the Dian Fossey Gorilla Fund (Fossey Fund) and the University of Exeter – shows groups that were previously united are more than four times as likely to be friendly to each other when they meet, even if they had split over a decade earlier. MORE
