摘要: We assessed behaviors involved with depositing and receiving scent in three captive heterosexual pairs of red-bellied tamarins (Saguinus labiatus). The frequencies deposition investigatory differed between the sexes. Females marked exclusively by anogenital gland. Males deposited 95.8% marks via gland 4.2% sternal at a significantly higher rate than that males (0.9 ± 0.1 versus 0.3 per 20 min, respectively). investigated their opposite-sex partners whereas females no male scent. Mean SEM latency for to investigate female was 208.7 65.0 sec. Around 9% all were overmarked within 8 min there nonsignificant trend overmark vice versa. discuss sex differences olfactory communication terms sexual selection theory.
