Abstract

A total of ten variables were measured from 175 individuals belonging to 91 carnivore species. A factor analysis of these variables was carried out to study the relation between scapular morphology and some aspects of the biology of the studied species, specifically size, locomotor behavior and habitat. Three factors accounting for 79.71% of total variability were obtained. The first factor (F1) was highly correlated to body mass, but at the same time it seemed related to the preferred habitat: forest and jungle species, as well as those living in watery environments, presented higher values of F1 than species with similar body mass that inhabited open spaces. The second factor (F2) appeared to be in relation with cursoriality, since positive values for cursorial species and negative
values for non-cursorial species were obtained. Finally, the third factor (F3) would be related to locomotor behavior, showing a tendency to increase F3 value from arboreal species to terrestrial ones (with scansorial and aquatic species displaying intermediate values). Unfortunately, this factor seemed to be highly influenced by taxonomic relationships at the family level. Consequently, no generalization could be postulated for Carnivora as a whole.
