International Biogeography Society biennial, Tucson, AZ

Last month I travelled to the US to attend the International Biogeography Society meeting in Tucson, Arizona where I gave a talk on my work investigating the biodiversity of the coastal forests of Eastern Africa using amphibians. The coastal forests are highly threatened and lacking rigorous assessment across them, especially involving genetic data. I used a method which identifies places that are special because they hold unique biodiversity and indicate refugia where biodiversity has persisted over time, while it has disappeared in surrounding areas (see the method here). I combined species distribution data with genetics to map geographic concentrations of evolutionary history and used environmental and historical climate data going back to the Last Glacial Maximum (~20,000 years ago) to see if the distribution of evolutionary history correlates with areas that have remained climatically stable over time. Results suggest that they do, and reinforces the idea that these parts of the coastal forest in East Africa are an important refuge for amphibians (and potentially other groups!) during times of severe climate change.

I find these kinds of methods really great because they enable us to pinpoint important areas to prioritise areas for conservation based on evolutionary history. This is particularly important given predicted future climate change and the impacts of deforestation in the tropics.
