Importance of natural biotopes for the utilization of ecosystem services by ground beetles (Carabidae) in a winter rape field
KDOLSKÝ, Tomáš
This diploma thesis deals with the importance of semi-natural biotopes for the carabid beetles (Coleoptera: Carabidae) and benefits of these beetles for the production of the oilseed rape. Evaluation was done by measuring the diversity of communities of carabid beetles by pitfall trapping followed by the evaluation of total abundance, Shannon´s diversity index and the Shannon´s evenness index in the field oilseed rape and in the adjacent semi-natural biotopes. Diversity was measured at two locations (location A, B). Monitored biotopes of the location A were the meadow, the field, the unmanaged field boundary and the forest. At the site B, monitored biotopes were the meadow and the field. Carabid beetles were captured in one-week intervals continuously from May to September 2013. In total 3076 individuals represented by 78 species were captured. The most numerous species in samples were Poecilus cupreus, Pterostichus melanarius, Poecilus versicolor, Pseudoophonus rufipes and Loricera pilicornis, which formed together 72 % of the total numbers. The monitored biotopes of location A did not differ significantly in total abundance (p = 0.13) nor in the Shannon´s eveness (p = 0.43). They differed by the diversity index (p = 0.03), but this accounted for difference between the field boundary and the forest biotopes (p = 0.04). No difference in the three measured parameters were found by the comparison the field sites and next semi-natural sites at locality A (i.e. meadow A/field A1, forest/field A2), nor by comparing the biotopes field and meadow in both the localities (A, B) in one model (p < 0.05). The results suggest the importance of the immigration of carabid from the semi-natural biotopes into the field, which supports the field populations of carabids and the ecosystem service of biological control provided by them.

Analysis of transport noise device on the transport environment.
KDOLSKÝ, Tomáš
This thesis contains the noise analysis of transport vehicles as cars, trucks, cargo sets, busses and motorcycles in relation of the kind of the transport environment, but also on the character of the transport routes. There are very important factors here and namely the kind of passing vehicles, the number of passing vehicles, the speed of the vehicles, weather conditions, road surface and road condition. Following to this analysis there is a summary of the results detected, which is mainly focused on the level of noise emissions in the individual measuring places. Afterwards, there are suggested ways of appropriate noise reduction. The object of this work is the pointing out potential excessive noise suggesting some possibilities of its removal at the measured places.
