Elasmobranch fisheries in the Arabian Seas Region

First published on 22. May 2017 Elasmobranch fisheries in the Arabian Seas Region: Characteristics, trade and management Rima W Jabado, Julia L Y Spaet ABSTRACT: The Arabian Seas Region plays an important role in the global landings and trade of sharks and rays.

A global overview of shark sanctuary regulations and their impact on shark fisheries

Published online on 11. May 2017 A global overview of shark sanctuary regulations and their impact on shark fisheries Christine A. Ward-Paige ABSTRACT: Due to rapid declines of shark populations across many species and regions of the world, the need for large-scale conservation measures has become widely recognized. Some coastal states have opted to implement

Skeletal Indicators of Shark Feeding on Human Remains

Published on 02. May 2017 Skeletal Indicators of Shark Feeding on Human Remains: Evidence from Florida Forensic Anthropology Cases Michala K. Stock M.A., Allysha P. Winburn M.A., George H. Burgess M. ABSTRACT: This research examines a series of six Florida forensic anthropology cases that exhibit taphonomic evidence of marine deposition and shark-feeding activities. In each

Mercury, arsenic, cadmium and lead in two commercial shark species in Trinidad and Tobago

Mercury, arsenic, cadmium and lead in two commercial shark species in Trinidad and Tobago

Published online on 21. April 2017 Mercury, arsenic, cadmium and lead in two commercial shark species (Sphyrna lewini and Caraharinus porosus) in Trinidad and Tobago Azad Mohammed, Terry Mohammed ABSTRACT: Sharks are long-lived apex predators which can accumulate toxic metals such as mercury and arsenic. Samples of Sphyrna lewini and Carcharinus porosus were collected from

X-ray computed tomography library of shark anatomy and lower jaw surface models

X-ray computed tomography library of shark anatomy and lower jaw surface models

Published online on 11. April 2017 X-ray computed tomography library of shark anatomy and lower jaw surface models Pepijn Kamminga, Paul W. De Bruin, Jacob Geleijns, Martin D. Brazeau ABSTRACT: The cranial diversity of sharks reflects disparate biomechanical adaptations to feeding. In order to be able to investigate and better understand the ecomorphology of extant

Clinical features of 27 shark attack cases on La Réunion Island

Clinical features of 27 shark attack cases on La Réunion Island

    Clinical features of 27 shark attack cases on La Réunion Island Ballas, Richard MD; Saetta, Ghislain; Peuchot, Charline; Elkienbaum, Philippe MD; Poinsot, Emmanuelle MD ABSTRACT: BACKGROUND: Between January 2000 and September 2016, there have been 27 documented shark attacks on La Réunion Island. The insular nature of La Réunion has allowed us to

White, G. J. Johnson, R. B. McAuley, M. R. Heupel ABSTRACT: Conservation and management of migratory species can be complex and challenging. International agreements such as the Convention on

Diet and condition of mesopredators on coral reefs in relation to shark abundance

Diet and condition of mesopredators on coral reefs in relation to shark abundance

Published on 19. April 2017 Diet and condition of mesopredators on coral reefs in relation to shark abundance Shanta C. Barley, Mark G. Meekan, Jessica J. Meeuwig ABSTRACT: Reef sharks may influence the foraging behaviour of mesopredatory teleosts on coral reefs via both risk effects and competitive exclusion. We used a “natural experiment” to test

Genetic structure and signatures of selection in grey reef sharks

Genetic structure and signatures of selection in grey reef sharks

Published on 19. April 2017 Genetic structure and signatures of selection in grey reef sharks (Carcharhinus amblyrhynchos) P Momigliano, R Harcourt, W D Robbins, V Jaiteh, G N Mahardika, A Sembiring, A Stow ABSTRACT: With overfishing reducing the abundance of marine predators in multiple marine ecosystems, knowledge of genetic structure and local adaptation may provide

A Brief Look at Human Impacts on Sharks

A Brief Look at Human Impacts on Sharks

Published on 05. April 2017 A Brief Look at Human Impacts on Sharks Strickland J. ABSTRACT: This brief review examines the many human activities that threaten sharks, their impacts, and the implications for the ecosystems that rely upon these apex predators. As keystone species, sharks play a crucial role in maintaining healthy ecosystems by asserting

Molecular basis of ancestral vertebrate electroreception

Molecular basis of ancestral vertebrate electroreception

Published online on 06. March 2017 Molecular basis of ancestral vertebrate electroreception Nicholas W. Bellono, Duncan B. Leitch, David Julius ABSTRACT: Elasmobranch fishes, including sharks, rays, and skates, use specialized electrosensory organs called ampullae of Lorenzini to detect extremely small changes in environmental electric fields. Electrosensory cells within these ampullae can discriminate and respond to
