Relative contribution to the shark fin trade of Indo‐Pacific and Eastern Pacific pelagic thresher sharks
Relative contribution to the shark fin trade of Indo‐Pacific and Eastern Pacific pelagic thresher sharks D. Cardeñosa, A. T. Fields, S. K. H. Shea, K. A. Feldheim, D. D. Chapman ABSTRACT: Fins from highly mobile shark species entering large shark fin trade hubs can originate from various geographical locations and stocks. Tracing fins from internationally
Forensic species identification of elasmobranchs landed in Costa Rican artisanal fisheries
Forensic species identification of elasmobranchs landed in Costa Rican artisanal fisheries Jason R.O’Bryhim, E.C.M. Parsons, Stacey L. Lance ABSTRACT: Elasmobranchs represent one of the most imperiled taxa, yet few nations have developed catch limits and no international or bilateral catch limits exist. One barrier to establishing catch limits is a lack of accurate species-specific extraction
Standardized data to support conservation prioritization for sharks and batoids
Standardized data to support conservation prioritization for sharks and batoids (Elasmobranchii) Rikke Oegelund Nielsen, Rita da Silva, Jacqueline Juergens, Johanna Staerk, Line Lindholm Sørensen, John Jackson, Simeon Quirinus Smeele, Dalia A. Conde ABSTRACT: We collated and synthesized information on 1,226 Elasmobranch species (i.e., sharks, rays, and skates) globally from a wide range of sources. We
Comparative morphology of shark pectoral fins
Comparative morphology of shark pectoral fins Sarah L. Hoffmann, Thaddaeus J. Buser, Marianne E. Porter ABSTRACT: Sharks vary greatly in morphology, physiology, and ecology. Differences in whole body shape, swimming style, and physiological parameters have previously been linked to varied habitat uses. Pectoral fin morphology has been used to taxonomically classify species and hypotheses on
The immunoglobulins of cartilaginous fishes
The immunoglobulins of cartilaginous fishes Hanover Matz, Danish Munir, James Logue, Helen Dooley ABSTRACT: Cartilaginous fishes, comprising the chimeras, sharks, skates, and rays, split from the common ancestor with other jawed vertebrates approx. 450 million years ago. Being the oldest extant taxonomic group to possess an immunoglobulin (Ig)-based adaptive immune system, examination of this group
