The connected areas had a more even size distribution than intermediate and isolated areas. S˘eric Jelaska et al. 2009 found that medium sized carabids have the hardest time dispersing out of the different size groups, they travel slower on the ground than the larger species and aren’t as good fliers as the small species. So, the medium sized species may have a hard time dispersing from the isolated habitats and therefore show up in higher densities than species that are more mobile. Even so the medium size was most abundant of all the sizes and the other size categories had much lower abundance, even in the connect areas so it might simply be more common.

Isolation didn’t show to have influenced species wing length. Northern Europe have generally a higher proportion of long winged species than southern Europe (Homburg et al. 2012). But the isolated areas did have fewer long winged species than the connected areas even if it wasn’t significant. The CA show that forest species were more common in the isolated and intermediate group. Short winged species are associated with undisturbed habitats such as mountains and forests (Venn 2016), which might be the reason why there are slightly more short-winged species in the isolated areas, since at least two of them were heavily surrounded by forest.
