Tiger sharks can connect equatorial habitats and fisheries across the Atlantic Ocean basin

Tiger sharks can connect equatorial habitats and fisheries across the Atlantic Ocean basin

Published on 19. September 2017 Tiger sharks can connect equatorial habitats and fisheries across the Atlantic Ocean basin André S. Afonso, Ricardo Garla, Fábio H. V. Hazin ABSTRACT: Increasing our knowledge about the spatial ecology of apex predators and their interactions with diverse habitats and fisheries is necessary for understanding the trophic mechanisms that underlie

Sawfish records along the Eastern Amazon coast

Sawfish records along the Eastern Amazon coast

Published on 05. September 2017 Sawfish (Pristidae) records along the Eastern Amazon coast Leonardo Manir Feitosa, Ana Paula Barbosa Martins, Jorge Luiz Silva Nunes ABSTRACT: Sawfishes are the most endangered cartilaginous fishes of the planet. Their external morphology facilitates entanglement in fishing nets and their K-selected life history hinders the recovery of exploited populations. The

A United States shark fin ban would undermine sustainable shark fisheries

A United States shark fin ban would undermine sustainable shark fisheries

Available online 8 September 2017 A United States shark fin ban would undermine sustainable shark fisheries D.S. Shiffman, R.E. Hueter ABSTRACT: A proposed nationwide ban on the sale of shark fins within the United States would undermine sustainable shark fisheries, would have little effect on global shark mortality, and would perpetuate the misconception that the

DNA analysis of traded shark fins and mobulid gill plates reveals a high proportion of species of conservation concern

Published on 25. August 2017 DNA analysis of traded shark fins and mobulid gill plates reveals a high proportion of species of conservation concern Dirk Steinke, Andrea M. Bernard, Rebekah L. Horn, Paul Hilton, Robert Hanner & Mahmood S. Shivji ABSTRACT: Continuously increasing demand for plant and animal products causes unsustainable depletion of biological resources.

Evidence for systemic age underestimation in shark and ray ageing studies

Evidence for systemic age underestimation in shark and ray ageing studies

Published on 23. August 2017 Evidence for systemic age underestimation in shark and ray ageing studies Alastair Varley Harry ABSTRACT: Numerous studies have now demonstrated that the most common method of ageing sharks and rays, counting growth zones on calcified structures, can underestimate true age. I reviewed bomb carbon dating (n = 15) and fluorochrome chemical marking

Shark bite injuries on three inshore dolphin species in tropical northwestern Australia

Published on 21. August 2017 Shark bite injuries on three inshore dolphin species in tropical northwestern Australia Felix Smith, Simon J. Allen, Lars Bejder, Alexander M. Brown ABSTRACT: Predation risk has a profound influence on the behavior of marine mammals, affecting grouping patterns and habitat use. Dolphins frequently bear evidence of shark bites, which can

A comparative morphological analysis of body and fin shape for eight shark species

Published on 19. August 2017 A comparative morphological analysis of body and fin shape for eight shark species Duncan J Irschick, Amy Fu, George Lauder, Cheryl Wilga, Chi-Yun Kuo, Neil Hammerschlag ABSTRACT: Sharks are diverse and ecologically important predators and are also highly varied in their biology and behaviour. Prior studies have posited basic relationships

Broad-scale movements of commercially important sharks

Published online on 18. August 2017 Acoustic monitoring reveals the broad-scale movements of commercially important sharks Matias Braccini, Kelly Rensing, Tim Langlois, Rory McAuley ABSTRACT: Information on broad-scale movements is required for spatial management and improved conservation of large marine predators.

Contrasting complexity of adjacent habitats influences the strength of cascading predatory effects

Published on 12. August 2017 Contrasting complexity of adjacent habitats influences the strength of cascading predatory effects James E. Byers, Zachary C. Holmes, Jennafer C. Malek ABSTRACT: Although cascading effects of top predators can help structure communities, their influence may vary across habitats that differentially protect prey. Therefore, to understand how and to what degree
