Preferences of pupils for different zoological objects in biology lessons
Sailerová, Barbora ; Mourek, Jan (advisor) ; Janštová, Vanda (referee)
The main object of this thesis was to find out whether grammar school students prefer zoological objects in biology lessons presented a) on photo in their natural habitat or b) the real specimen presented in liquid in glass cylinders and burettes. I have chosen these research questions: 1. In which form do pupils prefer zoological objects, the real specimen presented in liquid in glass cylinders or burettes or in their natural habitat on a photograph? 2. How do these preferences differ during the course of their high school study? 3. How do these preferences differ according to gender? 4. Are these preferences influenced by a specific animal? 5. Are these preferences influenced by other factors, e.g. by the appearance and personal experiences with live nature or frequency of using these objects in biology lessons. The research was implemented by using a questionnaire and a preferential test and was given to first and third year students from five Prague high schools. The conclusion of my research study shows that students prefer neither animals on photographs nor the real specimen presented as a liquid preparation. My research did not show that the preferences of the tested students were influenced by any of the tested factors, e.g. type of living, popularity of biology or students' grade in...

Morphological adaptations for nectarivory in birds
Sailerová, Barbora ; Hořák, David (advisor) ; Janeček, Štěpán (referee)
Scientists have been interested in adaptation of nectar-feeding birds for a long time. I tried to summarize information about these adaptation. About hummingbirds's, sunbird's and honeyeater's bill and tongue, about body size and how flower influences nectar intake. Nectar-feeding birds has extended and curved bill, which is an adaptation to flowers visiting by these birds. The tongue is a tool for nectar intake, its inner structure allows nectar intake. Tongue is tubular and hummingbird's and sunbird's tongue is proximal bifurcate, honeyeater's tongue has brush tip. Nectar-feeding birds are generally of small body size and larger species have to intake more insects because of higher energetic requirements. Some flowers don't allow to perch and nectar-feeding birds have to intake nectar in flight. Therefore especially hummingbirds and some sunbirds evolved a hovering. If its possible, these birds perch when they collect nectar.
