Phylogenetic analyses indicate that viviparity (live‐bearing reproduction) has originated
independently in more than 150 vertebrate lineages, including a minimum of 115 clades of …

The reproductive diversity of extant cartilaginous fishes (class Chondrichthyes) is
extraordinarily broad, reflecting more than 400 million years of evolutionary history. Among …

Elasmobranchs (sharks, rays and skates) are among the most threatened marine
vertebrates, yet their global functional diversity remains largely unknown. Here, we use a …

An annotated checklist of the chondrichthyan fishes (sharks, batoids and chimaeras) of the
world is presented. As of 7 November 2015, the number of species totals 1188, comprising …

In an effort to provide a framework for the accurate identification of elasmobranchs, driven in
large part by the needs of parasitological studies, a comprehensive survey of DNA …

The higher-level taxonomy of the stingrays (Dasyatidae) has never been comprehensively
reviewed. Recent phylogenetic studies, supported by morphological data, have provided …

DNA sequence data from mitochondrial genomes and c. 1000 nuclear exons were analysed
for a complete taxon sampling of manta and devilrays (Mobulidae) to estimate a current …

Here, we report trading of endangered shark species in a world hotspot for elasmobranch
conservation in Brazil. Data on shark fisheries are scarce in Brazil, although the northern …

An annotated checklist of chondrichthyan fishes (sharks, batoids, and chimaeras) occurring
in South African waters is presented. The checklist is the result of decades of research and …

Endothermy, ie the endogenous production of metabolic heat, has evolved multiple times
among vertebrates, and several strategies of heat production have been studied extensively …
