Description	Recently it was shown that individuals of the butterfly species Maniola jurtina do not seek resources by means of random flight. If true, this may be problematic for existing metapopulation models, including those based on the evolution of dispersal rates in metapopulations. The study tested to what extent the non-random dispersal patterns described in the literature can explain M. jurtina fluxes in its natural habitat. A model based on literature assumptions of M. jurtina movements is presented in the work reported here. The model provides a good fit to the data and gives better predictions than the model based only on patch sizes and distances between patches. Thus, if data are available about the actual landscape under consideration, the model should be preferred to simpler approaches; however, in general theoretical considerations the simple approach based on patch size and the degree of its isolation will retain its value.

(en) V současnosti bylo ukázáno, že individua motýla Maniola jurtina nevyhledávají zdroje prostřednictvím náhodných letů. Pokud by to byla pravda, mohlo by to problematizovat existující nepopulační modely včetně těch, které jsou založeny na evoluci schopnosti šíření v metapopulaci. (cs)
