Influence of visibility in water column on predation pressure in predatory aquatic insects
 PODHRADSKÁ, Eliška
The influence of abiotic factors on predation behaviour in predatory aquatic animals is reviewed. The most important factors are turbidity, light intensity and complexity of the environment. These abiotic factors are often combined with biotic factors. The second important part of thesis is the description of functional responses and influence of changes of visibility on individual components of predation behaviour. The review is complemented by laboratory experiments on two selected species of aquatic insects.

Challenges of Bengal tiger (Panthera tigris tigris) conservation in the tropics: lessons learned from the Chitwan National Park of Nepal
 BHATTARAI, Bishnu Prasad
This research deals with the challenges of the conservation of tiger (Panthera tigris tigris) in the Chitwan National Park of Nepal and aims to be a model for tiger conservation in the tropical areas of other tiger range countries. Despite the high level of public concern and major investments during the last few decades for conservation, wild tigers continue to be under grave threat, and their preservation now requires, more than ever before, using reliable ecological knowledge for their conservation interventions. In this dissertation, I investigated various factors that affect on tiger conservation in this park: population status of prey, dietary patterns of tiger and its impact on sympatric carnivores (e.g., leopard) and increasing human-wildlife conflicts, effects of habitat structures and human disturbances on prey and predator species abundance and distribution.
