An educational program aimed at value of postindustrial sites from the view of conservation biology
PŘIBYL, Karel
The aim of this bachelor thesis is to design and test an educational program that focuses on the importance of natural communities in post-industrial habitats. Post-industrial habitats due to a disturbance of the original landscape represent a specific environment with the potential for occurrence of often valuable and endangered communities. In the theoretical part there are summarized findings on mining disturbed zones with the occurrence of valuable species in terms of nature conservation. The practical part contains a draft of the educational program for sixth and seventh-grade pupils of the second level of primary schools. The thesis includes teaching materials and instructions for lecturers needed to implement the educational program. By completing the program, the participants gained fundamental information about the importance of post-industrial habitats in today's landscape as an area with often valuable nature.

Diversity of traits of aculeatan hymonopterans in habitats with finely-grained substrate
Wofková, Gabriela ; Tropek, Robert (advisor) ; Šlancarová, Jana (referee)
Natural habitats of aculeate hymenopterans are rapidly decreasing and strictly specialized species are thus going to be endangered or extinct. However, in the last decades the conservation potential of postindustrial sites has been found. There were many endangered and nationally extinct species recorded along with the drift sand specialists. However, one unclear thing remains - on postindustrial sites there were still no recordings of species that have similar biological traits to the species that are colonizing these sites. The main target of my thesis was to find traits which make it possible for the insects to colonize postindustrial sites. A matrix of 79 traits was made to describe aculeate hymenopterans biotope preferences, phenology, morphology, biogeographical area, nest, food and life history strategies. With these traits I describe 351 species systematically collected on twenty-one localities with finely - grained substrate found in Polabi and South Bohemia. These traits were tested with weighted mean abundances on type of substrate (artificial vs. sandy) with GEE analysis and the type of locality (dumping ground of coal combustion, ore and sand sludge vs. sandpits vs. natural sand) with PCoA analysis. A phylogenetic correction was incorporated in both analyzes. My results show that on...

Effect of succession and reclamation on wasps and bees (Hymenoptera: Aculea) on combustion by-products deposits
Eštok, Pavel ; Hendrychová, Markéta (advisor) ; Růžička, Jan (referee)
This diploma thesis summarises the available information about the importance and significance of post-industrial areas from the environmental point of view and information about natural conditions of the Central Bohemian Uplands (České středohoří) in the region of the town Louny. The thesis concerns especially the characteristic areas of the combustion by-products deposit of Třískolupy I and Třískolupy II which are connected with the Počerady brown coal power plant.
The practical aim of the thesis is to evaluate the effect of the different ash-material management on the presence of the aculea Hymenoptera (Hymenoptera: Aculeata), regarding especially its diversity and the presence of the rare species.
In the thesis, reclaimed areas have been compared with the areas in which spontaneous succession is proceeding. For the data collection, hymenoptera have been trapped in coloured plates filled with the salty solution of water and detergent, so-called Moerickeho pan traps.
From particular sampling sites 638 hymenoptera individuals have been collected through the monitored period of time and classified into 98 species and 13 families. Based on the collected samples it was possible to compare the differences between the succession and the reclamation sites. On the areas developing spontaneously more species and individuals were observed. In total, 26 rare species from Red List were recorded.

Ecology and conservation of invertebrates at anthropogenic sites
TROPEK, Robert
This thesis deals with communities of arthropods (and partly also vascular plants) colonising diverse anthropogenic sites. It reveals a conservation potential of these sites and focus on ecological requirements of both whole communities and individual species generalising these findings for usage in restoration of these sites.
