Behavioural patterns exhibited by three populations of house mouse ( Mus musculus lato) in five-tests battery: the effects of subspecies and commensal way of life
Voráčková, Petra ; Frynta, Daniel (advisor) ; Macholán, Miloš (referee)
The term "personality" nowadays occurs more often not only in psychological studies of humans but also in animal studies. Studying of personality help us to define the behavioural characteristics which can vary within the age, sexes, species or enviroments. Behavioral experiments are used to detect these behavioral patterns and they can divide the animals into the different groups. The subject of our research became three populations of house mouse (Mus musculus sensu lato) which we tested in a series of experiments involving free exploration, forced exploration, hole- board test, test of vertical activity and Elevated plus-maze. These experiments should reveal wheter the mice differ in their behaviour through the context of sex, comensalism or subspecies. We found (with in excepcion of one test) that intrapopulation variability differences are very small but interpopulation differences purely increase in the cas of comensalism and effects of subspecies. Keywords: Mus musculus, comensalism, open fieldtest, Elevated plus-maze, Principal Component Analysis (PCA)
Rats of the genus Rattus: their biology and food preferences
Voráčková, Petra ; Frynta, Daniel (advisor) ; Telenský, Petr (referee)
Genus Rattus falls into the most extensive mammalian family Muridae, concretely to subfamily Murinae. The Norway rat (Rattus norvegicus) and black rat (Rattus rattus) are the best known species of genus Rattus. Although the laboratory rat is widely used as model organism, the wild species of genus Rattus cause huge economic losses in agriculture, especially in South East Asia. These commensal rodents are also vectors of zoonotic deseases which can cause human infection. One of the way how to reduce their populations is to study the transmission of food preferences. Well known phenomenon of genus Rattus is the social learning and sharing the experience about food to other individuals. Not only due to this fact is this kind one of the most successful in the animal kingdom.
Diagrams in the high school mathematics
Vernerová, Ivana ; Voráčková, Petra (referee) ; Odvárko, Oldřich (advisor)
This dissertation handles about an appearance of diagrams in high school mathematics and their use for solving of different problems. It features several kinds of diagrams, their dissimilarities and their ways of use. It also shows how together cohere logic and set theory. The work can help like a basis for mathematics teachers in high schools, in mathematics seminars or in hobby groups for mathematics. Enclosed is also a CD which includes an electronic form of this work.
