DNA Barcoding Identifies Endangered Sharks in Pet Food Sold in Singapore

DNA Barcoding Identifies Endangered Sharks in Pet Food Sold in Singapore Ian French, Benjamin J. Wainwright ABSTRACT: Shark populations have declined by more than 70% over the past 50 years. These declines have largely been attributed to increases in fishing efforts. Despite increased public awareness surrounding the conservation of sharks, three-quarters of all oceanic shark

Combined phylogeny and new classification of catsharks

Combined phylogeny and new classification of catsharks

Combined phylogeny and new classification of catsharks (Chondrichthyes: Elasmobranchii: Carcharhiniformes) Karla D A Soares, Kleber Mathubara ABSTRACT: This is the first study to combine morphological and molecular characters to infer the phylogenetic relationships among catsharks. All currently valid genera classified in the family Scyliorhinidae s.l. and representatives of other carcharhinoid families plus one lamnoid and
