Landscape structure and biodiversity - a proposal of landscape structure to reach higher biodiversity and sustainability in cadaster of Pěčín (Landscape Protected Area Orlické hory)
 LEDEČOVÁ, Jana
In the present planning work there was studied the influence of anthropogenic load of the species of epigenic beetles in the cultural landscape. The landscape fragmentation has the primarily very significant impact on the ability of the survival of populations of beatle species. Using ground traps filled with ethylene glycol was realised capture of epigenic samples. The samples were classified according to the degree of tolerance to the antropogenic load into three groups. The first group forms eurytop samples with neutral habitat demands, which occurs in habitats very influenced by human being . The second group (RII) consists of more adaptable samples capable populate habitats medium influenced by man. The last one consists of samples with closest ecologic quantivalence - the relicts of I.cohort (R I). They have often character of relicts and in our monitored localities were not find on the whole. The traps were installed in four types of locations - cultural forest, wildlife corridor, field and along the stream. All the sites were located in the land register of the willage Pěčín in the part which is situated in the protected landscape area of Eagle mountains. The highest activity of samples and specimens was recorded in the field where predominated europyt sorts. In the other stations were higher occurence of more adaptable species. The land composition has the influence above all on the generic constitution of communities. In the landscape with a higher fragmentation and more land use predominate eurotop samples with less demands for habitat. Construed study confirmed this presumptions.
