Global assessment of shark strandings

Global assessment of shark strandings

Global assessment of shark strandings Natascha Wosnick, Renata D. Leite, Eloísa P. Giareta, Danny Morick, Michael Musyl ABSTRACT: Marine wildlife stranding is a global phenomenon, and for some taxonomic groups, these events are well monitored and documented. Although sharks are among the most threatened vertebrates, strandings have historically been neglected, with little information on this
