Butterfly dispersal in inhospitable matrix: rare, risky, but long-distance
Original language description
Metapopulation models typically assume that suitable habitats occupied by local populations and unsuitable matrix separating them form a blackand- white landscape mosaic, in which dispersal is primarily determined by the spatial configuration of habitatpatches. In reality, however, the matrix composition is also likely to influence dispersal. Using intensive mark-recapture surveys we investigated inter-patch movements in Maculinea (Phengaris) nausithous and M. teleius occurring sympatrically in six metapopulations. Three of these metapopulations had the matrix dominated by forest, an inhospitable environment for grassland butterflies, whereas in the remaining three the matrix was mostly composed of open environments. Dispersal parameters derived withthe Virtual Migration model revealed significant differences between both groups of metapopulations. Both species had a lower propensity to emigrate from their natal habitat patches, and they suffered substantially higher dispersal mortal
