Shark Cognition and a Human Mediated Driver of a Spate of Shark Attacks

Published in October 2014 Shark Cognition and a Human Mediated Driver of a Spate of Shark Attacks Marie Levine, Ralph S. Collier, Erich Ritter, Moustafa Fouda, Vincent Canabal ABSTRACT: Five unprovoked shark attacks are reported from Sharm-El-Sheikh, Egypt, between 30 November and 5 December 2010. Three of the five attacks are attributed to an oceanic

The role of refugia in reducing predation risk for Cape fur seals by white sharks

Published on 16. October 2014 The role of refugia in reducing predation risk for Cape fur seals by white sharks Michelle Wcisel, M. Justin O’Riain, Alta de Vos, Wilfred Chivell ABSTRACT: Refugia play an important role in shaping predator/prey interactions; however, few studies have investigated predator–prey relationships between large marine vertebrates, mainly due to the

Genetic Diversity and Population Structure of the Pelagic Thresher Shark in the Pacific Ocean

Published on 22. October 2014 Genetic Diversity and Population Structure of the Pelagic Thresher Shark (Alopias pelagicus) in the Pacific Ocean: Evidence for Two Evolutionarily Significant Units Diego Cardeñosa, John Hyde, Susana Caballero ABSTRACT: There has been an increasing concern about shark overexploitation in the last decade, especially for open ocean shark species, where there

When Did Carcharocles megalodon Become Extinct? A New Analysis of the Fossil Record

When Did Carcharocles megalodon Become Extinct? A New Analysis of the Fossil Record

Published on 22. October 2014 When Did Carcharocles megalodon Become Extinct ? A New Analysis of the Fossil Record Catalina Pimiento, Christopher F. Clements ABSTRACT: Carcharocles megalodon (“Megalodon”) is the largest shark that ever lived. Based on its distribution, dental morphology, and associated fauna, it has been suggested that this species was a cosmopolitan apex
