A DNA Sequence–Based Approach To the Identification of Shark and Ray Species and Its Implications for Global Elasmobranch Diversity and Parasitology
TLDR
A comprehensive survey of DNA sequences derived from the mitochondrial NADH2 gene was conducted for elasmobranchs collected from around the world, suggesting 79 potentially new taxa that are genetically distinct from their closest relatives in other regions. Expand
Elasmobranch Phylogeny: A Mitochondrial Estimate Based on 595 Species
Interest in elasmobranch biodiversity and taxonomy has grown in recent years, catalyzed primarily by four influences: (1) the large number of new species that have been described over the past 30Expand
Orders out of chaos--molecular phylogenetics reveals the complexity of shark and stingray tapeworm relationships.
TLDR
The present analyses contribute significantly to an understanding of the evolutionary radiation of the entire Cestoda and indicate that elasmobranch tapeworms comprise the backbone of cestode phylogeny. Expand
On the phylogenetic relationships among tetraphyllidean, lecanicephalidean and diphyllidean tapeworm genera
TLDR
The tetraphyllideans, lecanicephalideans and proteocephalideans are more closely related to each other than they are to the diphyllideans or the trypanorhynchs, and some aspects of the classification of the lecanICEphalidean and tet graphyllidean taxa require revision. Expand
Proposal for a new tapeworm order, Rhinebothriidea.
TLDR
Histological sections and scanning electron microscopy of selected members of the study group suggest that the presence of bothridial stalks may serve as an effective morphological feature to characterise the new order Rhinebothriidea, restricted to elasmobranchs. Expand
Evolution of the major lineages of tapeworms (Platyhelminthes: Cestoidea) inferred from 18S ribosomal DNA and elongation factor-1alpha.
TLDR
A general pattern of evolution was observed and the Tetraphyllidea, as currently defined, was found to be paraphyletic without the inclusion of the orders Proteocephalidea and, possibly, Lecanicephalidea. Expand
FOUR NEW SPECIES OF ACANTHOBOTHRIUM (CESTODA: TETRAPHYLLIDEA) FROM THE WHIPTAIL STINGRAY DASYATIS BREVIS IN THE GULF OF CALIFORNIA, MEXICO
TLDR
Examination of the spiral intestines of 29 whiptail stingrays from 6 sites in the Gulf of California, México in 1993 and 1996 resulted in the discovery of 4 new species of Acanthobothrium, the first record of either of these genera of onchobothriid tapeworms from the gulf of California. Expand
A Digest of Elasmobranch Tapeworms
TLDR
The tapeworms of elasmobranchs and their hosts are now among the most well documented host-parasite systems in existence, but this system has not yet reached its potential as a resource for investigations of basic ecological and evolutionary principles. Expand
