Abstract

Intra- and interspecific encounters were staged in the laboratory using adult brown anoles Anolis sagrei, and green anoles Anolis carolinensis, two species believed to be in competition in southern Florida. Agonistic behaviour of resident males toward heterospecifics was much less intense than that of resident males toward conspecifics. This suggests that behavioural interference between males is unlikely to be an important component of competition between these species. In staged encounters between males and females, courtship behaviour was usually observed only in conspecific encounters, and copulation was observed exclusively in conspecific encounters. This suggests that copulation between these species is uncommon under natural conditions.
