Attitudes of zoologists and general public on breeding of different groups of mammals kept in zoo
Vágnerová, Kristýna ; Trnka, Radek (advisor) ; Karadžos, Alexis (referee)
The aim of the thesis is to answer the question how differ the attitudes of zoologists and general public on suitability of various mammals kept in zoos. The theory of cultural stereotypes is theoretical starting point where i assume that evaluation is influenced on the basis of cultural stereotypes among general public (n = 100) versus expert evaluation of graduates of zoology (n = 60). Questionnaire with a scale enumeration concerning the assessment of the suitability of selected groups of mammals for breeding in zoos was used as the main data collection instrument. Results of the survey showed that experts evaluated the suitability of mamals for breeding in zoo more positive than laymens in general. According general public were equines and rodents rated as relatively unsuitable for breeding in zoos in comparison with expert evaluation. Elephant, orangutan, platypus, tiger, bear and cheetah were rated as relatively suitable for breeding in zoos by general public against expert evaluation. The possible interpretation might be that these mammals belong to the most popular and therefore respondents want to experience personal contact with them. Statistical testing found no gender differences in the rating. Key words: zoos, public attitudes, zoologists' attitudes, mammals, cultural stereotypes,...

Behaviour and acoustic communication in Egyptian fruit bat
Vašíčková, Pavla ; Jahelková, Helena (advisor) ; Karadžos, Alexis (referee)
Egyptian fruit bats were observed in Prague Zoo, where stable conditions are provided (year-round food supply, stable temperature and roosts). The colony has bimodal breeding cycle. Births are synchronized and occur on the turn of April and May and in September. The mating occurs throughout the year but there is an increase during lactation and in the period outside parturitions. There is no obvious pattern in cluster dynamics. Bats roost in four clusters (left, middle, upper right and lower right). The presence of clusters throughout the year is stable except upper right cluster. There are changes in the number of clusters and in the number of individuals inside each cluster. Fruit bats occupy approximately the same spots in clusters, however young individuals show the highest variability. An autogrooming is balanced throughout the year, there is no regular pattern in the observation period and even no increase after artificial twilight. From these activities a licking of wing membranes and fur are the most often. The mother cares for her young especially during lactation and weaning, while the care decreases with a development of the young. This is especially true for the licking of the wing membranes. An allogrooming is the most common between male and female during lactation and in the period...
