Microsatellite Analyses of Blacktip Reef Sharks in a Fragmented Environment
Published on 09. April 2013 Microsatellite Analyses of Blacktip Reef Sharks (Carcharhinus melanopterus) in a Fragmented Environment Show Structured Clusters Vignaud T, Clua E, Mourier J, Maynard J, Planes S ABSTRACT: The population dynamics of shark species are generally poorly described because highly mobile marine life is challenging to investigate. Here we investigate the genetic

Published on 04. April 2013 The first confirmed cases of full albinism in rajid species Ball, R. E., Jones, C. S., Lynghammar, A., Noble, L. R. and Griffiths, A. M. ABSTRACT: Three albino skate specimens (Rajidae) were captured from the North Sea and English Channel between 2008 and 2011. Using DNA barcoding (COI gene) and
New eco study looks at Great white shark behavior
In a new study published in PLOS ONE titled, "White sharks (Carcharodon carcharias) scavenging on whales and its potential role in further shaping the ecology of an apex predator," Captain Chris Fallows from Apex Expeditions collaborated with University of Miami (UM) scientists Dr. Neil Hammerschlag and Austin Gallagher, to explore the behaviors of Great white sharks scavenging on dead...
White Sharks Scavenging on Whales and Its Role in Further Shaping the Ecology of an Apex Predator
Published on 09. April 2013 White Sharks (Carcharodon carcharias) Scavenging on Whales and Its Potential Role in Further Shaping the Ecology of an Apex Predator Fallows C, Gallagher AJ, Hammerschlag N ABSTRACT: Scavenging, a result of a temporary pulse of resources, occurs in virtually all ecosystems containing carnivores, and is an important energy transfer pathway
