Determinants and Congruence of Species Richness Patterns across Multiple Taxonomic Groups on a Regional Scale

Table 2

Spearman rank correlations for the species richness of the different taxonomic groups in Rhineland-Palatinate (modelled region) and Baden-Württemberg (the adjacent region used for model validation). We used arcsin-transformed data to calculate correlations. ***𝑃<0.001, **𝑃<0.01, *𝑃<0.05, n.s.: not significant.
