Résumé
This is the first study to document the natural history of Lemur catta, ring-tailed lemurs, outside of gallery forest environments : in xerophytic Didiereaceae-Euphorbia, bush habitat that represents over 90% of this species’ potential range. Moreover, this study is the first to document ring-tailed lemurs, or any primate species for that matter, as cactus dwellers. Data were collected for 15 consecutive months on two different troops in the Cap Sainte-Marie : CSM) area, which is Madagascar’s southernmost region. All-day follows, nutritional analyses, and health assessments were the methods used to test hypotheses on the following themes : a) behavioral flexibility, b) ecology, health, and nutrition, c) the shared use of space with humans, and d) the utilization of nonnative species. Significant findings include : extremely large home ranges, highly social and spatially cohesive : juvenile centered) groups, coexistence with Antandroy villagers, and diverse diets comprised of native species despite the population’s adaptation to Opuntia monacantha and Opuntia stricta. Based on these findings, I suggest that L. catta have historically been present in the CSM region, but that this population likely persists here today only because of the presence of Opuntia
