Effects of environment and genotype on dispersal differ across departure, transfer and settlement in a butterfly metapopulation.

Host plant abundance had the largest effect on departure, followed by grazing intensity and per cent of host growing in low vegetation (although the latter two were marginally non-significant; electronic supplementary material, table S1)—effects that are consistent in direction and magnitude with those predicting patch occupancy and abundance for the species in metapopulation models [ 53 ].
