dc.description.abstract The natural history and spatial ecology of the tree agama, Acanthocercus atricollis atricollis, was studied in the field and using preserved museum material. Acanthocercus a. atricollis conformed to the classic lizard life history model of a species exhibiting co- evolved traits, including tank-like morphology, high clutch volume and an ambush foraging strategy. Diet consisted of a broad spectrum of arthropods, but no evidence of intersexual trophic partitioning was found. Acanthocercus a. atricollis are sexually dimorphic in head size; males had longer and wider heads than females when body size was held constant. Dimorphism in morphology is presumably due to sexual selection. All age and sex classes occupied similar arboreal habitats, exhibiting a strong preference for large trees with high foliage cover and holes, which may have either reduced their conspicuousness or vulnerability to predators in some fashion. Higher quality males did not have higher levels of female-male overlap. Female distribution appeared to be more influenced by prey abundance than male quality, suggesting that variation in home range quality may affect male mating success in A. a. atricollis. The study provides a strong foundation for future studies on sexual selection in tree agamas. en
