Résumé |
The olfactory behavior of a captive population of crowned lemurs (Lemur coronatus)was studied during their annual breeding season in order to investigate its possible role in the fine-tuning of mating synchrony after photoperiodic initiation of reproductive activity. The frequencies of five stereotyped olfactory behavior patterns were recorded in four male-female groups during 315 1-hr observation sessions between October and March. The mean total scent-marking frequency of all males was positively correlated with their mean testicular size. Male anogenital-, head-, and allomarking frequencies decreased during the breeding season, whereas hand-marking frequencies remained constant. Male head-marking increased significantly in the 5 days preceding female vaginal estrus. |
