Specific response of primates to snake predators
Regásková, Kristýna ; Landová, Eva (advisor) ; Lhota, Stanislav (referee)
The specific response to snake predators in primates is due to long coevolution with snakes. This long coevolution has led to a specific and complex response in primates when confronted with snakes. The cues by which primates recognize snakes versus other types of stimuli may be based on olfactory or visual information. Reactions such as a priori fear or avoidance may be followed by various antipredatory responses such as specific vocalizations, avoidance behaviour, early escape or, conversely, active defence and mobbing. The response to venomous snakes and constrictors can vary in many ways based on the different threat they pose. Key words: Predation, mobbing, snake, primates, vocalization, anxiety

Efect of Group Size on Allogrooming in Ruffed Lemur
Tymr, František ; Lhota, Stanislav (advisor) ; Konečná, Martina (referee)
The thesis deals with Corporate Social Responsibility with an emphasis on corporate foundations. The first, theoretical part of the thesis defines Corporate Social Responsibility, discusses its history and also describes the implementation of the concept in the Czech Republic. The second part of the thesis deals with the legal definition of foundations and the history of foundations in general. A relatively new category of foundations are corporate foundations, which are analysed with the help of comparative analysis. Finally, the last part of the thesis presents case studies of five specific foundations.

People versus cormorants
Ulrychová, Michala ; Haluzík, Radovan (advisor) ; Lhota, Stanislav (referee)
Great Cormorant belongs to those animal species, whose feeding habits are in conflict with economic interests of humans. As predator feeding entirely on fish, Great Cormorants in Europe had been nearly hunted to extinction in the past and therefore classified as endangered species in 20th century. Because of conservation efforts and other positive factors involved, its numbers increased unprecedented and its distribution expanded across all Europe. From the early eighties ideal conditions for breeding were found also in Trebonsko Protected Land Area (PLA) in Southern Bohemia. Trebonsko is not only PLA but has been also known as center of Czech pond culture for many centuries. Appearance of Great Cormorant stirred up conflict between conservationist and fishermen, who suffered a financial loss. Purpose of this work was to approach background of this conflict and to present attitudes and opinions of all concerned parties. The study starded with media search and a set of questionnaires was completed by different groups as professional fishermen, conservationist, game fishermen, local citizens and tourists visiting the PLA. These questionnaires were qualitatively analyzed afterwards. Results revealed that the problem is not simply the controversy between fisherman and conservationists if the Great Cormorant...
