Global shifts in species richness have shaped carpet shark evolution
Global shifts in species richness have shaped carpet shark evolution Bret M Boyd, Jason C Seitz ABSTRACT: Background: The evolutionary processes that shape patterns of species richness in marine ecosystems are complex and may differ between organismal groups. There has been considerable interest in understanding the evolutionary processes that led to marine species richness being

Potential of electric fields to reduce bycatch of highly threatened sawfishes Kátya Abrantes, Adam Barnett, Maarten Soetaert, Peter M. Kyne, Adrianne Laird, Lyle Squire, Jamie Seymour, Barbara E. Wueringer, Jessica Sleeman, Charlie Huveneers ABSTRACT: Sawfishes are among the most threatened families of marine fishes and are susceptible to incidental capture in net fisheries. Since bycatch
Leveraging shark-fin consumer preferences to deliver sustainable fisheries
Leveraging shark-fin consumer preferences to deliver sustainable fisheries Xuehong Zhou, Hollie Booth, Mingzhe Li, Zhifan Song, Douglas C. MacMillan, Wei Zhang, Qiang Wang, Diogo Veríssimo ABSTRACT: At least one third of sharks and their cartilaginous relatives (Class Chondrichthyes) meet the IUCN Red List Criteria for being threatened with extinction. Overfishing is the primary threat, with
Investigating Attitudes Toward Sharks in Australia
