Abstract
Experimental tests were conducted to determine whether females and males of the tree-dwelling lizard Liolaemus tenuis (Tropiduridae) show intraspecifi c chemical recognition during breeding and postreproductive seasons. Animal s were individually maintained in plastic enclosures for one week. Thereaft er, the number of tongue-flicks that a lizard performed in the enclosure of a male, a female, its own home enclosure, and a control (unused) enclosure were recorded. In both seasons, males and females made fewer tongue-flicks in their home enclosures than in any other one, indicating a recognition o f a familiar place, probably a chemical self-recognition. Conspecific chemi cal recognition was season dependent. During the post-reproductive season, lizards tongue-flicked at similar rates in conspecific and control enclosur es, while during the breeding season enclosures of females elicited more to ngue-flicks by both sexes, and the overall tongue-flick rates were higher t han in the postreproductive season. Results are discussed within the contex t of the social system of the species.
