Mann-Whitney U test for the total carabid catch rate (number of individuals/trap*day), rarefaction standardized species richness, and the proportion of individuals of different ecological, trophic and dispersal groups of carabids. Disturbed (D) and control (C) stands were compared during 2003-2008; test statistics (U), statistical significance (asterisks), and mean and SD values for D and C are shown. Significance levels: *** – p < 0.001; ** – p < 0.01; * – p < 0.05; n.s. – p > 0.05.
