Specification of phylogenetic interrelations between skate-rays and sharks
There are several hypotheses concerning phylogenetic interrelations of the ray-skate other also called batoid elasmobranches with other orders of elasmobranchs. Most of these studies are based on morphological studies; however, none of them include the skate itself. Without skate the concept of inte...

| Summary: | There are several hypotheses concerning phylogenetic interrelations of the ray-skate other also called batoid elasmobranches with other orders of elasmobranchs. Most of these studies are based on morphological studies; however, none of them include the skate itself. Without skate the concept of interrelations of the Batoids will be incomplete. This work deals with a molecular study of ribosomal ITS1-2 regions by the maximum parsimony (MP) and neighbor joining (NJ) methods of analysis, including skate. It is important for understanding the phylogenetic interrelations of the Batoids. The complex of all combined ITS1-2 data with use of the both analyses disagrees with the definition of phylogenesis of the recent Elasmobranchs, which has been put forward by Compagno [1]. On the contrary, results of the ITS1 MP analysis confirm the definition of superorders Squalea and Galeomorphii, which was proposed by Compagno [1].[PUBLICATION ABSTRACT] |
