Table 3. Indicator value analysis for all combinations of the environmental clusters.

The group-size corrected Indicator Value (IndVal.g) represent the association value of a species with a given cluster. The p-value is based on 999 permutations. Asterisks code for p-values at signifcance levels of 5% (*) and 1% (**).
