MAPRU PhD student, Jonathan Botha, publishes work on Cape Gannets in Algoa Bay in Marine Ecology Process Series. 

Using a combination stomach content data and stable isotope analysis, Dicken et al. (2017) provide information on size-based and sex-specific variations in diet, trophic position and foraging habitat of tiger sharks (Galeocerdo cuvier) along the KwaZulu-Natal coast.

Marine Apex Predator Research Unit member, Danielle van den Heever, was recently interviewed by local news papers about her efforts to conserve the 'ghost' birds in the tropics.

She is researching the foraging ecology of the wedge-tailed shearwater, or locally known as "ghost' birds, that breed on islands within the Indian Ocean. Her effort will ultimately help improve the conservation efforts of these birds.

A new paper by MAPRU members, Tegan Carpenter-Kling, Jonathan Handley, Ryan Reisinger, David Green and Pierre Pistorius was recently published in Marine Biology. The research formed part of Tegan's MSc thesis and it is the first to describe the foraging behaviour and gentoo penguins at Marion Island using small GPS data loggers and depth sensor. It also describes a novel foraging strategy for seabirds.

Jonathan Handley and Pierre Pistorius's paper in Polar Biology describes the first record of a penguin trying to steal food from another penguin underwater.

Dr Ryan Reisinger of NMMU's Marine Apex Predator Unit will be presenting a pulic talk entitled "Cold killers, and other finned and flying beasts of the far south" at Bayworld / Port Elizabeth Museum on 29 March 2016.
