Antje Ahrends

Head of Genetics and Conservation

My research focuses on biodiversity conservation in the face of global environmental change. I am using field data combined with large-scale environmental datasets, GIS, and modelling approaches to study the distribution of biodiversity and ecosystem services, and to assess the impact of land use change, habitat loss and climate change. This is to (a) enhance the understanding of the drivers of biodiversity patterns, (b) make predictions on the impacts of future global change, and (c) evaluate options for mitigating these impacts. I mainly work in China, South East Asia, Tanzania, and the United Kingdom.
