Dr Rochelle Constantine is an Associate Professor in biological sciences and marine science at the University of Auckland. Her most recent multi-disciplinary, collaborative project is focused on The Hauraki Gulf - Tikapa Moana/ Te Moananui-a-Toi - an area described as a 'global hotspot for marine megafauna diversity'. Recent research used a DNA-barcoding to analyse whale poo and the zooplankton community in the Gulf to determine the Bryde's whale diet, the most adaptable baleen whale known and a resident of the Gulf. The whales eat plankton, which are themselves on the move in the wake of warming oceans - behaviour which can provide a heads-up about the much larger changes that will occur in the Gulf if climate change continues.
