Effects of hydropeaking on the attached eggs of a rheophilic cyprinid species
BARTOŇ, Daniel
Ability of eggs of asp (Leuciscus aspius) to survive an increased water velocity was tested in experimental condition as well as in situ. Hydropeaking occurs on the study site and can cause detachment of most spawned eggs.
Legal regulation of wild animal protection
Křížová, Barbora ; Fabšíková, Tereza (referee)
Legal Regulation of Wild Animal Protection Abstract The dissertation deals with the protection of wild animals and its legal regulation. Wild animals are protected within the biodiversity protection and nature and landscape conservation, which can be divided into territorial and species protection, while the dissertation focuses mainly on the species one. In addition to the explanation of basic terms, the dissertation consists of three main parts, which focus on the international, European Union and Czech legal regulation. The first part on the international law analyzes the Convention on Biological Diversity, the Convention on International Trade in Endangered Species of Wild Fauna and Flora, the Convention on the Conservation of Migratory Species of Wild Animals and the Convention on the Conservation of European Wildlife and Natural Habitats. The next part on the European Union law mentions pertinent conceptual tools and subsequently the relevant directives and regulations. These include, above all, the Birds Directive, the Habitats Directive, the Zoos Directive, the Regulation on the Protection of Species of Wild Fauna and Flora by Regulating Trade Therein, and the Regulation on Invasive Alien Species. The third main part pays attention to the Czech legal regulation. First, representative conceptual...

Possibilities of ex situ protection of rare and endangered plant species
Vítová, Jana ; Münzbergová, Zuzana (advisor) ; Dostálek, Tomáš (referee)
The aim of the bachelor's thesis is to present the possibilities, significance and possible problems of ex-situ protection for the future conservation of biodiversity of plants on Earth. In the introductory part of the thesis, the individual processes and programs of ex situ protection are described, with the help of literature search. At the same time, information on international cooperation in the field of seed banks and botanical gardens is presented, which, through their activities and mutual cooperation, create rescue programs to secure as many samples of plant material for possible future use. The work also mentions international plant databases, which provide the accurate and detailed information about the preserved material of rare and endangered plant species for the public. Further in the thesis, the currently known problems of ex situ protection with their impacts on the collected and stored material are mapped. Keywords Ex situ conservation, threatened plants, Ministry of the Environment, database, seed dormancy, inbreeding, outbreed depression, cultivation, seed bank, botanical gardens, tissue cultures, in vitro, genetic drift, mutation, hybridization, wildlife conservation, endangered species, threatened species
Effects of hydropeaking on the attached eggs of a rheophilic cyprinid species
BARTOŇ, Daniel
Effects of artificial water fluctuations called hydropeaking on the detachment rates of adhesive eggs were studied using a rheophlic fish (asp Leuciscus aspius) as a model species. I attempted to relate egg density to abiotic conditions of the spawning ground and identify optimal conditions for the eggs. Egg densities were also studied during spawning season when hydropeaking occurred. In the experimental setup, egg detachment rates were tested with different speeds, substrate type and exposition time and critical conditions for the eggs were assessed.
Understanding wildlife distribution in the human-dominated landscape of Nepal:implications for conservation
PAUDEL, Prakash Kumar
In this thesis, I have first reviewed biodiversity status and its conservation in Nepal, which indicates the need of linking the gaps between research and conservation of rare and endangered flora and fauna. Using three mountain ungulates as model species (barking deer - Muntiacus muntjak, Himalayan goral - Naemorhedus goral and Himalayan serow - Capricornis thar), I have investigated effects of human disturbances on wildlife distribution in the human-dominated landscapes of western Nepal, spanning from the subtropical Bardia National Park to the mountainous Shey Phoksundo National Park. I have developed habitat suitability maps for these three ungulate species and recommended a conservation priority area for their conservation. A special emphasis was placed on the study of the distribution of Himalayan serow using different factors related to habitat fragmentation, hunting and patch characteristics and connectivity of forest in midhills landscape of Nepal. Finally, wildlife hunting pattern in the region was investigated in order to explore wildlife conservation issues from the social perspective.
