Table 2
Dominant species and indicator species for each diatom community. Dominant species with an abundance over 5% are given. Stars after the abundance are given if the species is a significant indicator species: ***: p < 0.001; **: p < 0.01; *: p < 0.05; +: p < 0.1. Groups A2 and B2 were represented by only one lake therefore indicator species were not possible to calculate for these groups.
