Winter teritoriality im passerines in relation to environmental and climatic conditions
Glückseligová, Pavla ; Musil, Petr (advisor) ; Reif, Jiří (referee)
This thesis is focused on winter territoriality of passerines. It summarizes general knowledge of territories, territorial behaviour and broader knowledge about winter territoriality. Winter social behaviour of individual species, their territoriality, migratory strategy and food preferences were summarized for Western Palearctic bird species. Furthermore, effect of climate change on passerines and their migratory behaviour, timing of breeding and their relationship to food abundance and conspecific competition. In the last chapter, there is discussed effect of climate change on species displaying wintering territoriality. Increasing temperature can affect food availability, competition for sources and consequently reproduction success.

Assessment of the state of Natura 2000 locations protecting Dusky and Scarce Large Blue butterflies. Can other endangered species and habitats profit from the protection of these sites?
Glückseligová, Pavla ; Křenová, Zdeňka (advisor) ; Kindlmann, Pavel (referee)
Land-use change that took place in the second half of the 20th century affected population sizes and viabilities of many species adapted to extensive land use. Dusky and Scarce large blue butterflies are ones of these species. Both number of their populations and population sizes declined all over Europe. During the last decade, many protected areas of the Natura 2000 network have been established to preserve these butterfly species. Protected areas are managed specifically to support viability of the Maculinea populations. This thesis investigates a current status set of the Natura 2000 sites in southwest Bohemia protecting one or both Maculinea butterfly species. Implementation of the specific management was found to be a crucial factor for successful protection of the Dusky and Scarce large blue butterflies. We found that there are significant differences in managements applied in different locations. Almost half of protected areas are managed in inappropriate ways, their butterfly population sizes were very small or already extinct. Other sites are managed well and stable Maculinea populations live there. An assumption that a specific Maculinea management could also support another rare or endangered species has been tested in this thesis too. All available records (i.e. field inventories,...
