A couple weeks ago, we had the pleasure of welcoming Dr. Adam Barnett to the lab for more than a week. Adam has been doing some really interesting work on sevengill and tiger sharks, and hopefully we can get some projects going together soon! He also has been working on a great website with lots of information. Check it out at http://www.oceansiq.com!
I'll turn it over to him for a brief update of what he's been up to!
Among other projects, I have been working on sevengill sharks Notorynchus cepedianus in the temperate waters of south-east Australia and South Africa, and tiger sharks Galeocerdo cuvier in north-east Australia (soceansiq.com), effectively studying two important apex predators in the two differing systems. The sevengill shark work in Tasmania Australia has been quite comprehensive, using a range of methods to show their habitat use patterns and the important role they play in coastal ecosystems. The study in South Africa has only recently begun and our focus site is False Bay, where we will also be identifying habitat use, the importance of the aggregation site in False Bay and the sevengill sharks’ role in the ecosystem. We will also examine if this role varies when they share the coastal system with white sharks
To date, our tiger shark work has focused on the movement patterns of this species at Raine Island, the largest green turtle nesting site in the world.
