(Uploaded by Plazi for the Bat Literature Project) Differences in skull morphology between two cryptic species of bat, Pipistrellus pipistrellus (n = 14) and P. pygmaeus (n = 15), originating from Great Britain, were investigated. Four different data sets were analysed: (1) 23 landmarks and (2) 26 l...

| Summary: | (Uploaded by Plazi for the Bat Literature Project) Differences in skull morphology between two cryptic species of bat, Pipistrellus pipistrellus (n = 14) and P. pygmaeus (n = 15), originating from Great Britain, were investigated. Four different data sets were analysed: (1) 23 landmarks and (2) 26 landmarks on the dorsal and ventral sides of the cranium, respectively, (3) 49 landmarks on the upper jaw, and (4) 34 landmarks on the labial side of the mandible. For almost all data sets, when compared within sex groups, P. pipistrellus were significantly larger than P. pygmaeus; the biggest difference being observed in the mandible size. Interspecific differences in shape, analysed by Principal Component Analysis and Discriminant Function Analysis (DFA) of the Procrustes superimposed landmarks, were also mostly visible in the mandible, and were related to dietary differences between the species. For example, the longer and more upright canines of P. pipistrellus allow them to pierce harder prey, the bigger ... |
