Butterfly species differing in mobility show different structures of dispersal‐related syndromes in the same fragmented landscape

摘要: Mobility varies strongly between and within species, reflecting different dispersal strategies. Within such differences can imply suites of traits associated in syndromes. Different syndrome structures have been found species among populations differing the selective pressures they are exposed to. Similarly, we expect mobility to show response similar as landscape fragmentation. Using butterflies originating from same fragmented landscape, investigated four common (Pyronia tithonus, Pararge aegeria Maniola jurtina, Pieris rapae) known differ their mobility. We expected individuals less mobile display a resident strategy because high cost this more larger range movement Moreover, syndromes only be detected whenever strategies, observable where polymorphism is maintained. thus stronger correlations mobility-related species. three tests controlled conditions designed measure components mobility, showed that were indeed correlated most The absence correlation may explained by low variation being counter-selected.
