Table 1.
Spearman's rank correlation coefficients (rs) calculated between the site distance from the ice edge and site variables (n = 102). *in the definition of vegetation complexity the grassland and wetland environments were assumed to be the least complex, followed by dwarf-shrub heath and Salix heath. **grain size was defined as the peak size value in the grain size distribution.
