Supplementary Online Material Table S2 Species inventory of the spider fauna in Dadia National Park and results from Redundancy analysis (RDA) after 1000 Monte-Carlo iterations. The canopy column shows the negative or positive relationship between each species (1-136) and the canopy cover factor; 61% of the total variance of species composition was explained by this factor. Species with an asterisk (seven in total) have been proposed as new species for science (Komnenov et al. 2016).

Species inventory of Orthoptera fauna in Dadia National Park and results from Redundancy analysis (RDA) after 1000 Monte-Carlo iterations. The column with herb height, cover of rocks and canopy cover shows the negative or positive relationship between each species (1-39) and each factor; 46.5% of the total variance of species composition was explained by the three factors.
