- Abstract
In matrilineal species, females and their offspring are organised within a group along lines of female kinship, i.e. matrilines or natal breeding groups. In some gregarious artiodactyles, daughters remain associated with their mothers into adulthood. To test this on a solitary living artiodactyle, the bushbuck ( Tragelaphus scriptus), home-range overlap, social vicinity and differentiated social relations between related and non-related females were used as indicators for the existence of matrilineal structures. Results of numerical classification and matrix correlation of social and spatial vicinity were matched with known kin relations indicating the existence of natal breeding groups among females. An extended home-range overlap between kin suggested restricted movements of females and therefore a female residence or philopatry. Differentiated and consistent female relationships signified matrilineal structures and suggested a competitive regime between female clans. We therefore conclude that complex kinship structures also exist in non-gregarious ungulate species.
