On the Quest of Studying Elasmobranchs within Complex Intertidal Ecosystems.

Over the last decade, scientific research and conservation work focused on sharks and rays has increased vastly due to the dramatic population and increased media attention for these species groups.

Measuring Hammerhead Sharks with Lasers

Although we published this paper already two (almost three, geez!) year ago, I think it is a paper worth sharing here as well. Together with Craig O’Connell (O’Seas Conservation Foundation) and a whole expedition team we set out to try a novel technique to non-invasively identify and measure great hammerhead sharks (Sphyrna mokarran). The technique…

Conservation Science in the Desert

Expedition to the beautiful Mauritania In West-Africa lies a large country that probably not many Europeans ever heard about, the Islamic Republic of Mauritania. I had the privilege to travel to the biggest national park of Mauritania, as you might expect from me by now, for a shark related study (yes, sand sharks..). The Country…
