Biology of three-toed woodpecker
Navrátil, Martin ; Fuchs, Roman (advisor) ; Reif, Jiří (referee)
In my thesis I have tried to find out how does forest management influence presence of the Three-toed woodpecker Picoides tridactylus.This species is considered a "flagship species" of an untouched primeval type of forest and therefore it requires our attention and protection. The thesis contains results of North-American studies focused on the species very similar to Picoides tridactylus. The main chapters are those aimed to provide information about how is the Picoides tridactylus affected by forest fragmentation, stand health condition and finally the impact of food supply on the occurence and behaviour of the species.

Recommended adaptation and mitigation measures in risk areas of natural occurrence fires in the light of the changing climate
Trnka, Miroslav ; Čermák, Petr ; Kudláčková, Lucie ; Balek, Jan ; Semerádová, Daniela ; Brovkina, Olga ; Zemek, František ; Štěpánek, Petr ; Zahradníček, Pavel ; Bláhová, Monika ; Cienciala, Emil ; Beranová, J. ; Zatloukal, V. ; Albert, J. ; Tumajer, J. ; Možný, M. ; Hájková, L. ; Chuchma, F.
The methodology formulates graded adaptation and mitigation measures to mitigate fire risk and spread fire in the countryside (forest and agricultural land). To this end, a variant assessment procedure is presented fire risk according to the user's data capabilities. The algorithmization of fire risk in forests is based on forest typology to assess habitats, and adds forest vegetation characteristics. On agricultural Soil agronomic factors include crop type, cover cover, habitat and water characteristics regime. For both territorial categories, the expected impacts of climate change on fire risk are given habitat in the medium term (by 2050). Methodology in conclusion on a case study demonstrates the possibilities of using the model tool FlamMap for the analysis of fire characteristics.

Influence of fire disturbance on the heathland vegetation in the Protected Landscape Area Brdy.
Pánková, Karolína ; Adámek, Martin (advisor) ; Fabšičová, Martina (referee)
of the thesis Heathlands are an unique semi-natural element of European landscape, which historically evolved under continuous man land-use pressure. In conditions of our country, this biotope is relatively rare in occurrence and small in area. In the former military training zone Brdy, Protected landscape area nowadays, there are heathlands of great extent developed due to deforestration and history of fires and mechanical disturbances of the soil surface and vegetation, which used to accompany military trainings. After the termination of military use of the locality, there is a risk of gradual degradation of the biotope caused by tree encroachment, litter accumulation which inhibits generative regeneration of the heath, and degeneration of the heath itself. This thesis aism to entangle influence of the fire on the heathland vegetation in the area with special attention given to vitality and structure of heath stands. The fieldwork was focused on the dynamics and species composition of the vegetation, including bryophytes and lichens, separately on the long-term scale (up to 80 years) and the short-term scale (permanent plots in the recently burnt vegetation). Experimental part of the thesis tested germination of the seeds from Brdy area under the conditions of fire and with presence of different...

Soil macrofauna (Diplopoda, Chilopoda, Oniscidea) in a pine forest disturbed by wildfire
Tajovský, Karel
The effect of wildfire on the soil invertebrate assemblages was studied after a large-scale fire in 1992 in the secondary pine forests in the Záhorie Lowland, Western Slovakia. Two plots differently affected by fire and one control plot with non-burned pine plantation were investigated during 1993-1995 for soil macrofauna. Soil sampling and pitfall trapping were used and parameters of millipede, centipede and terrestrial isopod assemblages were analyzed in detail. Among the soil macrofauna no survivors were found after the fire. Animal groups possessing a higher ability of migration (e.g. ants, larvae and adults of Diptera and Coleoptera) represented the first colonizers of the completely burned out pine plots. Centipedes, the representatives of predators, migrated and recolonized the open burned out plots more rapidly than saprophagous millipedes and terrestrial isopods, even they formed specific and relatively stable populations in non-disturbed surrounding plantations. Successional development of less disturbed plot was characterized by presence of some millipede and isopod species already during the first year after the fire event. These species (esp. the millipedes Cylindroiulus boleti and Proteroiulus fuscus) represent subcorticolous inhabitants, which explain their higher ability to survive the fire. The slow restoration processes after the wildfire should be attributed more to the destruction and elimination of litter layers and the above ground vegetation cover, rather than to the immediate eradication of soil animal assemblages, since most of them were completely absent after the fire event.
