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

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

No persistent behavioural effects of SCUBA diving on reef sharks

No persistent behavioural effects of SCUBA diving on reef sharks

Published on 13. March 2017 No persistent behavioural effects of SCUBA diving on reef sharks Darcy Bradley, Yannis P. Papastamatiou, Jennifer E.

Most existing studies of marine recreation ecology have focused on

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
