An erroneous range for the LDA overlap analyses in multivariate E-space was stated in the methods section (subsection: Comparison of climatic niches). Instead of a range of 0 (no overlap) to 1 (total overlap), the parameter ranges only from 0 (no overlap) to 0.5 (total overlap). Due to random group predictions when two groups cover identical E-space, the maximum discriminance value cannot exceed 0.5. Thus, an overlap of 0.32 (±0.057) (results section, subsection: Comparison of climate niches) rather indicates a “modest” than a “low” overlap. However, general conclusions as stated in the discussion section are not altered as the climate at invasive locations still nests within the substantially larger occupied E-space of the native population.
