Résumé
Behavioural characters are still insufficiently used for inferring phylogenetic relationships in systematics. This study is aimed at analysing the possible interest of behavioural studies for resolving relationships in Cervids, a topic hotly debated for decades. Recent molecular studies seemed to be reaching a consensus, but these results are in contradiction with morphology-based phylogenies. A preliminary study of the behavioural repertoire in females of 9 Cervid species showed some congruence with other approaches, but with insufficient clade support, hence we performed a complementary study of male vocal behaviour in 11 species. We used 18 characters, including types of calls (barks and roars) and their acoustic characteristics (composition, fundamental frequencies and formants). The resulting topology and phylogenetic consistency of behavioural characters were compared with those of molecular phylogenies, and a simultaneous parsimony analysis of behavioural and other data was performed. Our results show that vocalizations constitute relevant phylogenetic characters for this taxonomic group and allow for inferring plausible evolutionary scenarios in association with other behavioural characters.
