mean individual biomass - Opis:
- The study included 15 isolated islands, grouped in five size classes. Trapped individuals were identified to species and measured and weighted. The number of carabid species was higher in the ecotone zones as compared with the island interior. Reduction in total number of carabid species was observed with increasing size of an island. The share of forest related carabid species was positively correlated with the size of an island; similar was the pattern concerning the large zoophages, the European and brachypterous species. The larger an island, the higher value of the mean individual biomass index (SBO) and the index of Progressive Features Sum (SCP). With the growing size of the islands, the carabid communities are placed still further to the uppermost right hand corner in the SCP/SBO diagram (fig. 2). Response of carabid communities to different size forest islands has shown that the smallest islands which favor the establishment of stable forest communities are 0.63 ha. Hence, it is to consider in the practice of forest management to create islands not smaller than that area (this may be established at the level of about 1 ha, for the practical purposes).
