I’m currently employed as a field technician for the Zurich-Aldabra Research Platform (ZARP) researching giant tortoises on the isolated Aldabra atoll. My salary and costs were provided by a grant awarded to ZARP by the Forschungskredit of the University of Zurich. ZARP aim to understand more about the ecology of the tortoises, how they influence the atoll and how the atoll influences them, alongside investigating the effects of climate change. A sub-population of tortoises on Picard Island has been marked and sampled over the past 12 months which is essential to study genetic relatedness, individual behaviour and population dynamics. We have also attached GPS tags to 31 tortoises to study their movement behaviour around the atoll. I aim to write my MSc thesis on trying to understand what triggers tortoise movements and how they use the different vegetation types.
