Title: | Braincase-body size relations in European newts (Triturus spp., Salamandridae, Caudata): Does size matter? | Authors: | Vukov, Tanja Ivanović, Ana Tomašević Kolarov, Nataša Džukić, Georg Kalezić, Miloš |
Issue Date: | Jun-2007 | Project: | “Patterns of amphibian and reptile diversity on the Balkan Peninsula”, grant 143052 | Journal: | Annales Zoologici Fennici | Abstract: | A significant positive correlation between braincase size (used as a proxy for brain size) and body size was found in six European newt species, with considerable variation among the species. The observed variation in braincase size, however, could not be solely explained by variation in body size. In spite of female-biased sexual dimorphism in body size, which was especially pronounced in Triturus alpestris, the sexes did not differ in braincase size. We also found that T. dobrogicus had a much smaller braincase than would be expected considering its body size. This in addition to its different morphology and ecology sets it apart from related species of the crested newt group. |
