Description: Ecological niches within squamate reptiles are delineated by diet, microhabitat use, and activity period. In the current study field data were gathered to characterize the ecology of Rhacodactylus auriculatus with regard to these three axes. Rhacodactylus auriculatus regularly consume a wide taxonomic and ecological variety of arthropods, lizard prey including geckos and skinks, and various plant materials including flowers, flower parts, and sap. Based upon the variety of dietary constituents and the regularity with which they are utilized, R. auriculatus may have the most atypical of all gekkonid diets. Rhacodactylus auriculatus partition microhabitat with conspecifics based on perch height, presumably to avoid aggressive interactions. Specimens were most active from one to four hours after sunset, temporally separating them from sympatric diurnal skinks. As supported by dietary comparison with 30 gekkonid lizards, diet is more important in segregating R. auriculatus from sympatric gekkotans than is typically the case among lizards.* *This dissertation is a compound document (contains both a paper copy and a CD as part of the dissertation).
