Spatial organization and spatial distribution of activities within home ranges in a Springbok (Antidorcas marsupialis) captive population.
We studied over 1 year the spatial organization and the spatial distribution of activities in a captive springbok (Antidorcas marsupialis) population living in an 18-ha enclosure located in southern France. Throughout the study period, the two adult males occupied fairly exclusive home ranges, in the overlapping part of which the three subadult males were restricted. The spatial and temporal distribution of aggressive, marking, and avoidance behavior of males showed that the two adults were territorial, except during summer. They accounted for 71% of all marking behaviors recorded, for 77% of the aggressive behavior, and for 91% of the sexual interactions, whereas subadult males accounted for 94% of the avoidance behavior observed. The adult females used the whole enclosure, moving through the males' home ranges. They fed everywhere, but they all had the same preferred resting area, located in the center of the territory of one of the two adult males. They gave birth, accounted for maternal behavior and were engaged in sexual interactions in sectors differing from one individual to the other, but mainly outside the sector where all males' home ranges overlapped. Our results are compared to those reported in natural conditions and lead us to discuss both the functional interpretations of marking behavior, and the signification of a home range for an ungulate.
