How do evolutionary processes shape animals into different lineages forming the biodiversity that we find today? Questions like these drive my enthusiasm to do research projects as presented here. The bat species M. waterhousii which apparently occurs as distinct morphotypes, appears to be a promising candidate to understand and study the forces driving the evolution of this Genus. My multidisciplinary approach aims to identify and assess the influence of morphology, echolocation behaviour, social interactions and molecular genetics as evolutionary forces acting in concert shaping the...
