I recently came back from Evolution2018 in Montpellier, one of the largest gatherings of evolutionary biologists in the world to date (almost 3000 delegates from over 60 countries). There I presented some upcoming work using multi-species RAD-seq datasets to test competing diversification processes in tropical biodiversity hotspots. Although the last decades of DNA-based research have vastly improved our knowledge of biodiversity patterns in poorly known tropical regions we lacked the high resolution genomic data needed to uncover the processes which are responsible for these patterns.
With high-throughput genomic data, our work tested if areas of forest which have remained stable over long periods of time (millions of years) are responsible for the diversification of amphibian populations within several co-distributed species, or if these diversification events can be attributed to alternative processes (e.g. mountain barriers, river barriers, ecological gradients or human influence).
This paper has just been accepted in Molecular Ecology, I will post an update when it is properly published as a PDF. In the meantime a snippet of this work is shown below in the attached poster, and you can find the accepted manuscript (not yet typeset) here.
