In the paper the author attempts to carry out a comparison between the floristic composition and structure of plant communities present in cereal crops of the rural areas of the Siedlce Upland and the floristic composition and structure of the analogue plant communities found in the area of Siedlce, which is the biggest town of this geographic mesoregion. Tables of the following syntaxons were analysed...
The study involved mice of an inbred CFW line from the authors own culture conducted according to the street light method (Lane Petter and Pearson 1971). All the animals, aged about 3 months and weighing 20 g each, were infected per os with 200 T. spiralis larvae per mouse. A total of 76 mice, divided into two groups, were used. Group I constituted the control and consisted of T. spiralis-infected...
The authors studied how genotypic variability within colonies affects their defensive response. Different genetic types of bees were used in the experiments. The influence of the artificially generated within-colony genotypic diversity on the colony defence was investigated. Common stinging assays were performed. Time to the first sting was (TFS) and the number of stings made to the leather target...
