Abstract
The “Difference of Evenness” (DE) index, based on the ratio of r- and K-strategists in benthic communities was proposed for a quick assessment of the ecological consequences of the introduction of the red king crab Paralithodes camtschaticus (Tilesius, 1815) from Kamchatka in the Barents Sea. It was found that the red king crab, which selectively eats medium-sized invertebrates, changes the size–age composition of the soft-bottom benthos towards the predominance of juveniles of long-lived species, which is equivalent to the abundance of small opportunistic species. The DE index values obtained for the coastal area of the Barents Sea at a settlement density of the king crab of 20 ind./1000 m2 or more indicated ecological stress to benthic communities of soft soils, that is, a change in the size composition and the degree of species dominance in terms of biomass.
