3.3 Wikipedia and biology Further investigation of topics in Czech Wikipedia was carried out in the field of biology and environmental education. Five topics used within the study (Callis,2009) were used in the first phase. They are the entries Pollination, Biological Dispersal, Herbivore, Frugivore and Seed Predation. Only two of these were found in the Czech version of Wikipedia and in both cases the entries were only very brief, consisting of fewer than 400 words. Subsequently the sample of the investigated entries was appended by topics selected from the requirements for state exams in biology at the Faculty of Education, Charles University in Prague. This study has shown that only about one half of these topics can be found in the Czech version of Wikipedia. The topics are usually treated very briefly and serve more like dictionaries and milestones (see the figure 3, the entry Pollination).
