The genetic consequences of abundance pattern and dispersal behaviour were studied using various butterfly species. Melanargia galathea (a widespread butterfly) versus Melitea aurelia (a specialist species, restricted to calcareous grasslands) were analysed to get information about the genetic consequences of these different distribution patterns. The dispersal behaviours of the two lycaenid butterflies Cupido minimus (a sedentary species) versus Aricia agesits (showing high turnover-rates of extinction and colonisation of habitats) were used to study the genetic effects of opposite dispersal behaviours. Measuring movements is an important objective in conservation biology to understand the connectivity of habitats in a landscape. Mark-release-recapture (MRR) studies were performed with different butterfly species to study intra- and inter-population movements, population sizes and individual life-times. The movement data were compared with genetic data. (markers: MRR, allozymes, funded by the German Research Fund DFG).
