Temporal variability in spatial distribution of carabid beetles in agricultural landscapes
Seidl, Miroslav ; Knapp, Michal (advisor) ; Harabiš, Filip (referee)
The aim of this thesis is to work out a brief literary research focused on spatial distribution of carabid beetles (Coleoptera, Carabidae) around arable field-woodland boundaries throughout the season. Substantial part of this thesis consistsof thefield experiment aiming to explore given issue in the model area near Sedlčany. Carabid beetles were collected employing pitfall traps along four transects perpendicular to arable field-woodlot boundaries. Beetles were sampled during five sampling periods, but only four complete (undamaged) temporal samples series were used for final statistical analyses:1) early spring, 2) late spring, 3) summer and 4) late autumn.Three species groups were identified according to their habitat specialization:1) open habitat specialists, 2) habitat generalists and 3) forest specialists; and these groups were analysed seperately.
Total species diversity was highest in area of ecotone between arable field and woodlot.The edge between habitats was preferred by habitat generalist species and open habitat specialist species also spilled over here. Distribution of relative species richness and relative activity density was not stable in time. Spatial distribution of forest species was relatively less variable. Open habitat species aggregated within habitat boundaries instead of field interiors in early spring, probably as a result of overwinteringbehaviour. Generalists were also aggregated in the edge between habitats in autumn period and during early spring occurred relatively more in the centre of woodlot than in other periods. Species composition of carabid beetles assemblages depended partly on season and also on position of transect. There was also a significant interaction between spatial and temporal variability in species composition of carabid assemblages. Woodlot assemblages seem to be less variable in time.
The results of this thesis contribute to extension of knowledges on distribution of carabid beetles in agroecosystems, where many carabids act aspredators of various pests. The biggest changes in spatiotemporal distribution of carabid beetles in agricultural landscape could be linked with preference of adults to overwinter out of arable land.

Pre-Hospital Urgent Care of Injured Motorcyclists at Traffic Accidents
SEIDL, Miroslav
Currently every day a great number of traffic accidents happens in our roads. Some accidents are followed by very serious injuries, which must be treated quickly and right. Recently many motorcyclists have been in this group of the seriously wounded and this number is still increasing. At the scene of the accident paramedics shall give the right and fast first aid mostly to a young person and they often decide on his/her life, eventually on its next quality. Paramedics must it be able to take off a protective helmet in the right way, stabilize patient´s essential vital functions and diagnose eventual shock or polytrauma. However not all the injuries can be diagnosed by paramedics with the available equipment at the scene of the accident. A good result is guaranteed in the increasing tendency of this accident rate first of all with paramedics continuous training at this specific problems. The aim of the bachelor thesis is an analysis of pre-hospital urgent care of injured motorcyclists at traffic accidents and set standard for treatment of these casualties by paramedics. The sample of respondents is represented by staff members of Health Rescue Service of South Bohemian Region and staff members of the Traumatological department of the Nemocnice České Budějovice, a.s. The data collection was performed by the methods of questioning, guided conversation and secondary data analysis. The research was performed in March 2010. Pursuant to the performed research the following hypotheses have been determined and the standard for treatment of an injured motorcyclist by paramedics has been created. Hypothesis 1: Paramedics use immobilizing tools in case of an injured motorcyclist in the right way. Hypothesis 2: Paramedics cannot take off the protective helmet in case of an injured motorcyclist in the right way.
