Biotechnology has a considerable importance in Turkish biology curriculum. This study was designed to explore or indicate Turkish high school and university students' knowledge and attitudes toward biotechnology. A total number of 352 high school and 276 university students were invited to the study. The Biotechnology Knowledge Questionnaire (BKQ) with 16 items and Biotechnology Attitude Questionnaire (BAQ) with 37 items were used as data collection instruments. The statistically significant correlation was observed between the level of biotechnology knowledge and the subdimensions of attitudes toward biotechnology. We found no statistically significant difference between high school and university students' knowledge of biotechnology. In contrast, university students showed more positive attitudes toward biotechnology than did high school students. However, the effect of gender was equivocal; therefore, it did not support a ''gender paradox'' hypothesis. Our results suggest that although students' appreciation of (agricultural) biotechnology is relatively positive, the understanding of biotechnology processes is superficial and attitudes toward shopping genetically modified products are therefore negative. The possible impact of current science and biology curriculum, and also biotechnology news given in media on Turkish students' views of biotechnology is discussed.

Th ere is an increasing amount of research focusing on the origin of the human fear of animals. However, other dimensions of human views of frightening animals have been largely neglected. Th is study investigated attitudes toward snakes. Th e Snake Attitude Questionnaire (SAQ), which consisted of 58 Likert-type items (Cronbach's α = 0.91), was administered in a sample of students from two countries (Turkey and Slovakia). Students showed negative attitudes toward snakes, especially within the Negativistic and Naturalistic dimensions. Turkish students showed more positive Scientistic and Naturalistic attitudes than Slovakian students, and females showed more negative attitudes toward snakes than males. Although biology majors had more positive attitudes, compared with nonbiology majors, knowledge of snakes and beliefs about untrue myths were similar between these two subgroups. Our research indicates that fear of snakes negatively infl uences other attitudinal dimensions (especially naturalistic and scientifi c attitudes) although no students had been injured by a snake. Keeping various pets at home was associated with less fear of snakes. Nature protection actions should combine direct contact with these controversial animals with interventions against belief in untrue myths about snakes.

Amphibians play an important role in the functioning of ecosystems and some of them inhabit human gardens where they can successfully reproduce. The decline of amphibian diversity worldwide suggests that people may play a crucial role in their survival. We conducted a cross-cultural study on high school students' tolerance of frogs in Chile, Slovakia, South Africa and Turkey (n = 655 high school students). We found that about 6 % of students reported active killing of frogs and 30 % reported moving frogs away from their home gardens. Pathogen disgust negatively correlated with frog tolerance suggesting that people who are more sensitive to pathogen conoting cues are less tolerant toward frogs. Tolerance of frogs in parents or other family members appears to significantly influence student tolerance of frogs. Females tended to show higher tolerance of frogs than males. This study highlights the importance of the emotion of disgust in human willingness to protect frogs from a cross-cultural perspective.
