Demographic and genetic consequences of habitat fragmentation


Since 1994 the Group of Animal Population Biology has initiated a series of projects on the ecology and genetics of populations from different taxa (butterflies, amphibians and birds) in their natural habitats. The general aim is to investigate which mechanisms are responsible for the adaptation of populations to selective pressures of a changing, heterogeneous environment. Possible mechanisms are (1) changes in demographic processes and/or (2) evolutionary responses by genetic differentiation. The relative importance of each mechanism is evaluated by coupling demographic and genetic studies of populations.
