Abstract
The upper dentition of Crocidura exhibits polymorphic characters that were revealed for the first time in this study via high-resolution X-ray computed microtomography. Our analyses of 11 Crocidura species and selected Diplomesodon, Suncus and Sylvisorex species from different geographical regions and size groups revealed the most complex character states of upper dentition in the Ethiopian endemic species Crocidura yaldeni. A three-dimensionally based geometric morphometric analysis revealed the dependence of variation in skull muzzle shape on alterations in general upper dentition, such as a reduction in the number of antemolars. Principal components analysis revealed highly significant shape alterations and morphological trajectories in C. yaldeni (and more moderate ones in Suncus murinus) toward the Sorex-like morphotype in the outgroup, and less significant shape alterations in Crocidura obscurior, Crocidura phanluongi and Crocidura sapaensis with double-rooted third antemolar. Cladistic analysis based on a new data matrix for 20 species and 46 characters allowed us to determine the directions of the morphological trajectories: the apomorphic state of the most complex antemolars of C. yaldeni is associated with deviating skull muzzle shape changes, which we determined to be attributable to neomorphosis, and the less significant alterations in the shape of other Crocidura with complex antemolars are attributable to regional adaptation.Read the article »
