Rural settlements as biocentres for carabid beetles v zemedelske krajine

The biodiversity of carabid beetles was studied using pitfall trapping in two small settlements in the agricultural landscape of southern Bohemia (Central Europe) and in the Vltava housing quarter of Ceske Budejovice. The results were compared with surrounding agricultural landscape. The highest number of carabid species in communities was found in the intensively managed agricultural landscape and in Vltava housing quarter. The number of species was lower in villages but the higher activity of stenotopic carabids was typical for these localities. Ordination of species did not found the distinct difference with exception of three species preferring wet biotopes with clay soils. Ordination of samples reflect the clear difference of samples from the surrounding agricultural landscape and samples from the Vltava housing quarter. Rural settlements are suitable for some stenotopic and protected carabids in monotonous agricultural landscape.

Byla pouzita metoda zemnich pasti. Vysledky byly porovnany s daty ziskanymi v okolni zemedeiske krajine. Nejvetsi pocet druhu ve spolecenstvech byl zjisten v intenzivne obhospodafovane zemedeiske krajine obklopujici vesnicka sidla a na panelovem sidlisti. Pocet druhu byl ve vesnicich nizsi, ale charakteristicka byla vyssi aktivita stenotopnich druhu. Ordinace druhu neprokazala zfejme rozdily mezi jednotiivymi studovanymi lokaiitami s vyjimkou tfi druhu preferujicich podmacene biotopy a jilovite pudy. Ordinace vzorku prokazala jasnou odlisnost vzorku z okolni zemedeiske krajiny a sidliste. Vesnicka sidla slouzi jako biocentra pro nektere stenotopni a zakonem chranene druhy v monotonni zemedeiske krajine.
