The influence of the type and age of post-mining areas restoration on biodiversity of small terrestrial mammals.
MIKLAS, Bořek
The aim of the study was to compare different types and ages of restoration from the small mammal biodiversity perspective. In 2004, three linear and two quadratic trappings of small terrestrial mammals were performed at the Velká podkrušnohorská spoil heap. Linear trappings were repeated in 2009 and quadratic were repeated in 2010. In 2004, 174 small mammals in the linear trappings and 199 small mammals in the quadratic trappings were captured. We found, that the wetland localities were the richest in small mammal diversity, the forestry restored areas were second ones, and the agriculturally restored areas were the poorest ones. During the repeated trappings, 45 small mammals in linear trappings and 64 small mammals in quadratic trappings were captured. A decrease of both abundance and biodiversity was recorded in the both types of trappings. The highest biodiversity was on wetland and forestry restored areas. The lowest biodiversity was on agriculturally restored areas. The highest abundance was on forestry sites during the linear trappings. The wetland areas were second ones and the lowest abundance was on agriculturally restored areas. Value of abundance in quadratic trappings was almost the same in wetland and forest habitats, whilst the abundance of agricultural areas was significantly lower. The results show the importance of wetland habitats, which are very important part of restoration and have a positive impact on the overall biodiversity in the landscape.

Influence different management on primary production and biodiversity epigeic and hemiedafic beetles in observed drainage area in Šumava.
KISSOVÁ, Lucie
Communities of epigeic beetles were studied on two water catchments with the different management in the submontaneous area of Bohemian Forest (South Bohemia, Czechia). The Mlýnský stream catchment was characteristic by high representation of unforested habitats (pastures and mowed meadows), Horský stream by higher proportion of forested habitats and non equal management (plots without management). The biomass characteristics (above ground and dry) were measured on studied plots. The method of pitfall trapping was used for beetle sampling. Beetle species were divided into two groups after its preferences to shaded: species occurring in unshaded habitats and species occurring in shaded habitats. The degree of human impact was studied by finding of frequency of species of different ecological groups. The above ground biomass was about 2 time higher in Mlýnský stream than in the Horský stream. The dry biomass was practically the same. 57 species was found in the Mlýnský stream and 33 in the Horský stream. The activity of beetles was about five times higher in Mlýnský stream than in the Horský stream. Ubiquitous species prevail in Mlýnský stream and adaptive species in the Horský stream. Stenotopic species were found in the Mlýnský stream only. These results indicate less human impact in Horský stream than in the Mlýnský stream. Beetles prefering unsheded habitats slightly prevail in Mlýnský stream in comparison with Horský stream. Beetle species characteristical for shaded habitats occur in Horský stream in comparison with Mlýnský stream. The geographical exposition affected the beetle structure mainly in the less forested plot of Mlýnský stream. The structure of communites situated to the south differs from communities situated to the north in Mlýnský stream. The effect of exposition is not documented in Horský stream with the greater proportion of forested size.

The influence of the type of post-mining areas restoration on biodiversity {--} the model group of small mammals.
MIKLAS, Bořek
One way to assess restoration success is to examine the biodiversity in the newly created areas. We chose small mammals as biodiversity indicators because of their good reproductive capacity and invasive ability. The aim of the study was to compare different types of restoration from the small mammal biodiversity perspective. Small mammals were captured five times during the 2004 season at spoil heap localities with various types of restoration: agricultural, forest and wetland, using standard methods of capturing with snap traps in lines and quadrates.

The belts along the roads as a biotope for organisms.
KRHUTOVÁ, Stanislava
The aim of the work was to describe the biodiversity of model groups of organisms (vascular plants, epigeic beetles and small mammals) in six transect crossing the two year old high way situated close to the town Písek (South Bohemia). The different methods were used for studied groups (phytocenological mapping, pitfall traps and mousetraps). The results documented the possibility of all studied organisms for the quick recolonization of new biotopes beside of the high way.
