Pelvic And Sacral Size Dimorphism And Allometry In Two Predatory Carnivores With Different Life Histories And Locomotory Adaptations, Alexander Csanady, Peter Krisovsky, Ladislav Hloska

Turkish Journal of Zoology

Sexual size dimorphism (SSD) of the wolf and the lynx was evaluated for 15 pelvic and sacral variables in 48 specimens from the Western Carpathians. Our data confirmed small male-biased SSD in the pelvic and sacral bones for both species. We suggest that this can be explained by the need for a compromise between requirements for locomotion and giving birth. We also confirmed that significant differences exist between the species in the size of the pelvic and sacral bones. We discuss our findings in light of the species? different life histories.
