| Description | Based on the analysis of two large data sets of species co-occurrence, sampled along the entire pH/calcium gradient, we explored whether species exhibit similar or different ecological behaviour in the two regions (West Carpathians, Bulgaria). A distinctive variation in the realized niche was observed in a large portion of the species examined. Ecotypic adaptation within species is a possible explanation for this pattern as other possible explanations seem to be less justified. The local populations of rich-fen species may have adapted to mineral-poor acid conditions in the high crystalline mountains of Bulgaria during dry periods of pleniglacials. |
