Range Overlap

Ranging behavior is one important strategy by which nonhuman primates obtain access to resources critical to their biological maintenance and reproductive success. As most primates live in permanent social groups, their members must balance the benefits of group living with the costs of intragroup competition for resources. However, some taxa live in more spatiotemporally flexible social groups, whose members modify patterns of association and range use as a method to mitigate these costs. Here, we describe the range use of one such taxon, the black-and-white ruffed lemur (<i>Varecia variegata</i>), at an undisturbed primary rain forest site in Ranomafana National Park, Madagascar, and characterize sex differences in annual home range area, overlap, and daily distances traveled. Moreover, we characterize seasonal variability in range use and ask whether ranging behaviors can be explained by either climatic or reproductive seasonality. We found that females used significantly larger home ranges than males, though sexes shared equal and moderate levels of home range overlap. Overall, range use did not vary across seasons, although within sexes, male range use varied significantly with climate. Moreover, daily path length was best predicted by day length, female reproductive state, and sex, but was unrelated to climate variables. While the patterns of range use and spatial association presented here share some similarities with “bisexually bonded” community models described for chimpanzees, we argue that ruffed lemurs best conform to a “nuclear neighborhood” community model wherein nuclear (core) groups share the highest levels of home range overlap, and where these groups cluster spatially into adjacent “neighborhoods” within the larger, communally defended territory.

This paper describes the results of field surveys for two Endangered lemurs, Milne-Edward's sifaka Propithecus diadema edwardsi and the black and white ruffed lemur Varecia variegata variegata, in the unprotected Fandriana-Marolambo forest corridor in south-east Madagascar. Published range maps show P. d. edwardsi and V. v. variegata present in the corridor, although few surveys have been conducted in this area. A total of 292.9 km of surveys were conducted at eight sites in the corridor but P. d. edwardsi and V. v. variegata were each located at only one site. Absence of these species at other sites may be the combined result of altitudinal and anthropogenic effects. Conservation plans for P. d. edwardsi and V. v. variegata are complicated because gaps in forest cover prevent dispersal of conspecifics from nearby protected areas. Conservation authorities should be cautious in using range maps based on the presumed distribution of lemur species.
