An experiment with sharks and beach safety policy options

An experiment with sharks and beach safety policy options

Published on 07. December 2017 Reducing fear to influence policy preferences: An experiment with sharks and beach safety policy options Christopher L. Pepin-Neff, Thomas Wynter ABSTRACT: This article reports on new research that finds certain messages reduce fear of sharks, key to promoting conservation-minded responses to shark bites. Here it is argued that the sophistication

Flaccid skin protects hagfishes from shark bites

Flaccid skin protects hagfishes from shark bites

Published on 13. December 2017 Flaccid skin protects hagfishes from shark bites Sarah Boggett, Jean-Luc Stiles, Adam P. Summers, Douglas S. Fudge ABSTRACT: Hagfishes defend themselves from fish predators by releasing large volumes of gill-clogging slime when they are attacked. Slime release is not anticipatory, but is only released after an attack has been initiated,

Fisheries-independent surveys identify critical habitats for young scalloped hammerhead sharks

Fisheries-independent surveys identify critical habitats for young scalloped hammerhead sharks

Published online on 08. December 2017 Fisheries-independent surveys identify critical habitats for young scalloped hammerhead sharks (Sphyrna lewini) in the Rewa Delta, Fiji Amandine D. Marie, Cara Miller, Celso Cawich, Susanna Piovano, Ciro Rico ABSTRACT: Sharp declines in numerous shark populations around the world have generated considerable interest in better understanding and characterising their biology,

Spatial separation without territoriality in shark communities

Spatial separation without territoriality in shark communities

Published on 16. November 2017 Spatial separation without territoriality in shark communities Yannis P. Papastamatiou, Thomas W. Bodey, Alan M. Friedlander, Christopher G. Lowe, Darcy Bradley, Kevin Weng, Victoria Priestley, Jennifer E. Caselle ABSTRACT: Spatial separation within predator communities can arise via territoriality but also from competitive interactions between and within species. However, linking competitive

Global evaluation of shark sanctuaries

Global evaluation of shark sanctuaries

Published online on 10. November 2017 Global evaluation of shark sanctuaries Christine A.Ward-Paige, BorisWorm ABSTRACT: Due to well-documented declines in many shark populations there is increasing pressure to implement new management and rebuilding strategies at the national and international scale. Since 2009, fifteen coastal countries in the Atlantic, Indian and Pacific Oceans have opted to

Physical trade-offs shape the evolution of buoyancy control in sharks

Physical trade-offs shape the evolution of buoyancy control in sharks

Published on 08. November 2017 Physical trade-offs shape the evolution of buoyancy control in sharks Adrian C. Gleiss, Jean Potvin, Jeremy A. Goldbogen ABSTRACT: Buoyancy control is a fundamental aspect of aquatic life that has major implications for locomotor performance and ecological niche. Unlike terrestrial animals, the densities of aquatic animals are similar to the
