The rank-abundance plots show (Figure 1) that three species were dominant (relative abundance >5%) when considering the total capture list (Harpalus distinguendus (176 specimens), Phyllotreta nigripes (41) and Harpalus amplieollis (24)).

Fig. 1: Species abundance curves for rapeseed and adjacent forest strip beetle cenoses (Sadaclia)

Rarefaction curves for rapeseed crop and forest strip beetle communities are shown in Figure 2. Expected number of species has been plotted against number of individuals. This plot provides a measure of species diversity. Stepper curve indicated that forest strip habitat is slightly
