Using location data from 1998 to 2017, we investigated within- and between-group competition in 12 groups of wild mountain gorillas (Gorilla beringei beringei). As within-group feeding competition is expected to increase with group size, an increase in group size is predicted to lead to an increase in the size of annual home ranges and core areas, but to a decrease in fidelity (reuse of an area). Due to asymmetries in competitive abilities, larger groups are expected to have higher exclusivity (degree of non-shared space) of annual home ranges and core areas than smaller groups. %K Gorilla beringei beringei, Mountain gorillas , Intraspecific competition , Home range size , Home range fidelity , Home range exclusivity , Competitive advantage , Intergroup aggression , Mate defense %J BMC Ecology %V 20 %] 40 %@ 1472-6785
