Mesophilous grassland butterflies of European interest under climate changes (Lycaena dispar, Lycaena helle, Phengaris nausithous, Phengaris teleius, Euphydryas aurinia)
Vrba, Pavel ; Faltýnek Fric, Zdeněk ; Rindoš, Michal ; Hájková, K. ; Konvička, Martin
Methodological material summarizing variants of the habitat conservation principles for butterflies inhabitting mesophilic and humid grasslands under various scenarios of climate change. The species of interest, protected by the EU Habitats Directive, are Euphydryas aurinia, Phengaris nausithous, Phengaris teleius, Lycaena dispar and Lycaena helle. It includes the predictions of suitable locations for spontaneous or assisted colonization.

Dry grassland butterflies of European interest under climate changes (Colias myrmidone, Parnassius apollo, Phengaris arion)
Faltýnek Fric, Zdeněk ; Konvička, Martin ; Rindoš, Michal ; Sucháčková Bartoňová, Alena ; Spitzer, Lukáš ; Vrba, Pavel
The methodology summarizes the principles of the habitat conservation of several butterflies - Phengaris arion, Parnassius apollo and Colias myrmidone, species specialized to dry grasslands, rock screes and similar habitats, under different scenarios of climate change. Maps of future climatically suitable habitats are included, together with an analysis of the possibilities of assisted colonization.

Endangered butterflies of lowland forests under climate change
Konvička, Martin ; Beneš, Jiří ; Číp, D. ; Sobík, D. ; Spitzer, L. ; Faltýnek Fric, Zdeněk ; Rindoš, Michal ; Vrba, Pavel
The material compiles conservation measures and methods for the care of endangered butterflies of open forests, protected by the EU Habitat Directive in the Czech Republic and under climate changes. These species are Euphydryas maturna, Lopinga achine, Parnassius mnemosyne, Coenonympha hero, and partially also Zerynthia polyxena. It results from predictions of vegetational and climatic changes of forest habitats, and outlooks of forest and water management conditions.

Corpus Analysis of Infinitive Forms in Verb Clusters in Dutch
Felbr, Lukáš ; Rezková, Iva (advisor) ; Konvička, Martin (referee)
This bachelor thesis presents a corpus analysis of verbal complexes containing three indefinite verb forms (i.e. infinitive or past participle). First, the individual verbs and constructions in these verbal complexes are categorised into classes based on their semantic-syntactic properties. This classification makes it possible to point out the boundaries and gaps of current research. Existing descriptions mainly emphasize formal aspects (such as word order). In this thesis, these aspects are left aside. The analytical part aims to describe and analyse non-finite constructions containing a modal verb, a verb tense auxiliary and a full verb. The thesis focuses mainly on the gaps in semantic descriptions of such verbal complexes. The corpus data reveal parallels between the forms of verbal complexes with epistemic and deontic modality, which partially contradict the theory described so far. In this paper, selected evidence from the corpus pointing to these parallels is described in more detail.

Nesting behaviour and alternative reproductive tactics in solitary bees (Hymenoptera: Apoidea)
Rezková, Kateřina ; Straka, Jakub (advisor) ; Konvička, Martin (referee)
Proposed thesis describes nesting behaviour of gregarious solitary bee species Andrena vaga. The knowledge of behaviour in solitary bees can be very important, because solitarity might represent the initial point in the evolution of eusociality and obligate cleptoparasitism. A population of the studied species was observed continuously for two nesting seasons, which enabled me to describe basic demographic characteristics of studied species such as lenght of bee season, longevity, density of population, number of nests per female life, etc. All the observed behavioural patterns were described in ethogram and their exact position in provisioning cycle was determined. This information helped me to compile average daily activity of studied species. I found out major differences in bee behaviour in both years and between nonparasitized and stylopized (parasitized by Stylops) bees. I proved the existence of intraspecific cleptoparasitism in form of usurpations. Because it is crucial to link female to the provisioned cell for the detection of intraspecific cuckoo-like behaviour, I tested two new methods of underground cell marking - protein marking and fluorescent dye marking.

Habitat as a determinant of abundance and distribution of birds in space and time
Reif, Jiří ; Storch, David (advisor) ; Fuchs, Roman (referee) ; Konvička, Martin (referee)
of the thesis The thesis focuses on various aspects of bird-habitat relationships. We found that the positive correlation between local abundance and regional distribution of birds is not a universal pattern. Its strength and direction depends on the similarity of habitat cover at the locality where the species abundances are measured and habitat cover of the wider region where the species distribution is assessed. In the case of the Cameroon Mountains, many locally abundant species had relatively small ranges in subsaharan Africa. They were probably well-adapted to specific conditions of montane environment, and such tight habitat association precluded their occurrence in regions covered by savannah or humid lowland forest. At the same time, isolation and unusual environmental conditions of the montane forest in the Cameroon Mountains reduced possibilities of their colonization by species widespread within Africa. Such species were confined to deforested areas in the Cameroon Mountains. The strongest gradient in bird community structure was between birds of montane forest and birds of non-forest habitats, and this gradient is probably one of the most important bird-habitat gradients worldwide. Endemic species and species confined to afrotropical mountains had the highest association with montane...
