Ohrožené druhy rostlin v národních parcích ČR: srovnání z pohledu chráněných fenoménů a managementových přístupů
Rejzková, Tereza ; Härtel, Handrij (advisor) ; Reif, Jiří (referee)
Bachelor thesis aims to contribute to currently on-going conservation debate on the role of the national parks (not only in the Czech Republic): to what extent should the national parks protect natural processes and to what extent the species / habitat diversity (e.g. Härtel 2009a, 2009b). The conservation background is represented by the management categories of the International Union for Conservation of Nature (IUCN) (Dudley 2008). General conservation dilemma between the concept of wilderness and protection of diversity by active management is currently stressed mainly by entomologists. This work aims to contribute to this topic based on data on endangered plant species (Grulich 2012) (including protected ones) in four national parks in the Czech Republic. Endangered species represent together with protection of the processes and diversity of inanimate nature (geodiversity) one of the conservation subjects of the national parks. The number of endangered species in the national parks as well as the species composition of this group illustrates the significant biogeographical differences between the Czech national parks as well as very different natural phenomena protected by the parks. Comparison of threatened species in the Czech national parks and habitat requirements of these species will,...
The Red List of lampreys and fishes in the Czech Republic - Version 2005
Lusk, Stanislav ; Hanel, L. ; Lusková, Věra ; Lojkásek, B. ; Hartvich, P.
The new Red List was compiled on the basis of data obtained in the course of five past years. Besides the overall evaluation for the Czech Republic, the data were separately evaluated for the North Sea, Baltic Sea, and Black Sea basins. The status and degree of danger imminent to the populations of the particular species were evaluated also separately for each of the 16 water regions. Compared to the 2000 evaluation, classification was changed for following species: Salmo salar (previously EW, now CE), Acipenser ruthenus (NE / CE), Sabanejewia balcanica (EX / CE), Zingel streber (EX / CE), Chondrostoma nasus (EN / VU), Lota lota (VU / NT), Rhodeus amarus (NT / EN), Leucaspius delineatus (NT / EN), Alburnoides bipunctatus (VU / EN), and Carassius carassius (VU / EN). The degree of jeopardy for Alburnoides bipunctatus, Vimba vimba, Rhodeus amarus, Carassius carassius, Misgurnus fossilis is basically different in different water regions, varying between Extinct and Near Threatened.
