Isolation does seem to influence body size and species composition in carabids. While the species number were similar throughout the isolation gradient, the groups held slightly different species. This probably because connected areas were found close to arable fields while the matrix of the more isolated areas were more mixed, so spill over species were different (Schneider et al. 2016, Taboada et al. 2011). The grassland carabid species were more common in the intermediate and isolated area group, so too much agricultural activities may have a negative effect on carabids like it has on butterflies (Öckinger et al. 2012). Poecilius cupreus did indicate for the connected isolation group but had a relative low indicator species value (0.59), this will make it hard to use it as an indicator species for un-isolated semi-natural grasslands. This carabid is also an agricultural field specialist which means it is more likely a spill over species.

Isolation does affect what species can be found in grasslands, body size and habitat preference especially. The surrounding area does seem to dictate some of the species found and to preserve semi-natural grasslands the whole landscape should be taken into consideration when restoring and managing grasslands.
