My research focuses on the consequences of dispersal limitation of big-fruited palms in Madagascar due to the extinction of the megafauna. Madagascar harbors exceptional biodiversity, but this tropical biodiversity hotspot also faces an increasing threat from human activities and climate change. Plants with very large, ‘megafaunal’ fruits are common across the flora of Madagascar, especially within the palm (Arecaceae) family. However, Pleistocene extinctions of large-bodied ‘megafaunal’ fruit-eating and seed-dispersing animals (such as giant lemurs or elephant birds) may have hindered the dispersal of taxa with these ‘anachronistic’, megafaunal fruits. In this project, we aim to investigate the micro-evolutionary consequences of dispersal limitation of anachronistic palms on Madagascar, using a comparative framework. For this, fieldwork will be carried out and next-generation genomic techniques (e.g. RAD-Seq) will be applied to infer (historical) connectivity, demographic history, and phylogeographical patterns of anachronistic and small-fruited Malagasy palms. The results will allow us to evaluate whether anachronistic, megafaunal-fruited palms on Madagascar are facing extinction or may be adapting to dispersal by smaller-bodied frugivores still present today.
