Craniological differentiation amongst Southeast Asian small cats
Abstract Nine small felid species, including the introduced domestic cat, inhabit Southeast Asia. We analysed their skull morphology, using 36 selected morphometric measurements of up to 465 specimens. Of the species examined, the fishing cat and the Asian golden cat were the largest, whilst the mai...

| description | Abstract Nine small felid species, including the introduced domestic cat, inhabit Southeast Asia. We analysed their skull morphology, using 36 selected morphometric measurements of up to 465 specimens. Of the species examined, the fishing cat and the Asian golden cat were the largest, whilst the mainland and Sunda leopard cats were the smallest. However, there was substantial overlap in size amongst these species. Principal Component Analysis and Quadratic Discriminant Analysis revealed that the skulls of fishing cats and flat-headed cats were clearly distinguishable from those of the other species. Additionally, the skulls of male Asian golden cats, female jungle cats, female Sunda leopard cats, and male marbled cats were well differentiated. In contrast, those of female Asian golden cats, male jungle cats, male domestic cats, and female marbled cats showed considerable morphological overlap with other morphospecies. When analysing only sympatric assemblages (i.e., on the continental mainland, Borneo, Sumatra, and Java), each morphospecies was generally well differentiated from the others although conspecific males and females were not clearly differentiated. Notable exceptions were female Asian golden cats and male jungle cats, female mainland leopard cats and female domestic cats, and female marbled cats and male domestic cats on the mainland, and female marbled cats and male domestic cats on Borneo and Sumatra. More detailed research is necessary to understand the impacts of introduced domestic cats on indigenous small wild felids in Southeast Asia through niche overlap and competition. |
