چکیده انگلیسی

Interspecific diversity exists in cranial suture closure patterns among mammalian species. Suture closure patterns partly reflect phylogenesis, but it has also been claimed that it is influenced by biomechanical factors. Here we provide the first report on the cranial suture closure pattern in water deer. Among cervids, the water deer is an exceptional species, as it is the only one without antlers. Instead, the male water deer possess prominent canines, which are utilized during male-male combats. This unique morphological setting allowed us to examine whether the presence of prominent canines affects cranial suture closure. We found that the only sexual difference in cranial suture closure pattern is the closure of the interfrontal suture in males, which is found in some other cervid species as well. Except for the interfrontal suture closure, timing and sequence of cranial suture closure were comparable between both sexes, suggesting that the presence of prominent canines in males has no influence on cranial suture closure pattern. Our results indicate that interfrontal suture closure in males is a phylogenetic pattern, i.e. an apomorphy for Capreolini, Hydropotini and Alceini.
