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

Stress, post-release mortality, and recovery of discarded deep-sea sharks

Published on 06. Nomber 2017 Stress, post-release mortality, and recovery of commonly discarded deep-sea sharks caught on longlines Brendan Talwar, Edward J. Brooks, John W. Mandelman, R. Dean Grubbs ABSTRACT: Bycatch interactions with deep-sea elasmobranchs are increasingly common and can lead to dramatic declines in abundance over short time scales. Sharks hooked in the deep

Sawfish captures in the Queensland Shark Control Program, 1962 to 2016

Published online on 17. October 2017 Sawfish captures in the Queensland Shark Control Program, 1962 to 2016 Barbara E. Wueringer ABSTRACT: Within the Great Barrier Reef World Heritage Area in Queensland, Australia, lack of information on the distribution of sawfishes presents difficulty for informed management of their habitats and populations. This study aims to provide

Studying morphology allows the detection of bias in routine fisheries sampling

Published online on 16. October 2017 Shark length–length relationships: Studying morphology allows the detection of bias in routine fisheries sampling Agustín M. De Wysiecki, J. Matías Braccini ABSTRACT: Reliable information on length–length relationships is required for standardising and comparing size measures and for improving the use of available data and biological information collected as a

Reef accessibility impairs the protection of sharks

Published online on 17. October 2017 Reef accessibility impairs the protection of sharks Jean-Baptiste Juhel, Laurent Vigliola, David Mouillot, Michel Kulbicki, Tom B. Letessier, Jessica J. Meeuwig, Laurent Wantiez ABSTRACT: Reef sharks are declining world-wide under ever-increasing fishing pressure, with potential consequences on ecosystem functioning. Marine protected areas (MPAs) are currently one of the management
