Ecology of endangered damselfly \kur{Coenagrion ornatum} in post-mining streams in relation to their restoration
 TICHÁNEK, Filip
The thesis explores various aspects of ecology of endangered damselfly Coenagrion ornatum, the specialists for lowland headwaters, in post-mining streams of Radovesicka spoil. The first part of thesis is manuscript which has been already submitted in Journal of Insect Conservation. In the first part, we focused on population estimate of the local population using capture-recapture method, and explored its habitat requirements across life stages and spatial scales. In the next part, I assess mobility of the focal species and reveals basic distribution patterns. Finally, the thesis suggest various implications for restoration of post-mining freshwaters and conservation of the studied species.

Genetic variation and reproduction strategy of Gentiana pannonica in different habitats
 EKRTOVÁ, Ester
The reproduction strategy and genetic variability of Gentiana pannonica, an endangered species in the Czech Republic, were studied. The differences of vegetation composition, seedlings recruitment, seed set and genetic variation within and among six various populations G. pannonica in the Šumava Mts. and two populations in the Alps of this species were investigated in a field. The vegetation composition differs between primary and secondary habitat of G. pannonica and seedlings recruitment was recorded only in primary habitat. The reproduction output of the study species is probably influenced by sufficient amount of pollinators. No serious genetic diversity between populations in the Šumava Mts. and the Alps was found. The genetic differences were found only between populations on the primary habitats and populations on the secondary mountain meadows.
