The spatial distribution pattern and associated social interactions of Oplurus cuvieri cuvieri were studied in a deciduous dry forest of Ampijoroa, Madagascar. Home range sizes were significantly larger in males than in females. In both sexes, snout-vent length was not correlated with home range sizes. Home range of males overlapped both inter- and intrasexually. Female home ranges rarely overlapped intrasexually. Consexual aggressive interactions indicated the presence of territoriality. Distribution pattern and observed intersexual interactions suggested a polygynous mating system. Site fidelity was observed for both home range and shelter tree levels. Tail breakage was moderately frequent, implying high predation pressure and the importance of safety refuge. No sexual differences were observed in thermal environment, perch height, or perch diameter, whereas sexual dimorphism in body size and dorsal color pattern was found. More than 80% of the lizards of both sexes performed “resting”.
