Refugial ecosystems in central Asia as indicators of biodiversity change during the Pleistocene–Holocene transition

Popis výsledku v původním jazyce

Site-scale species richness (alpha diversity) patterns are well described for many present-day ecosystems, but they are difficult to reconstruct from the fossil record. Pesent-day central Asian ecosystems exhibit climatic features and biota similar to those of the full-glacial periods in Europe. We measured alpha diversity of vascular plants, bryophytes, macrolichens and landsnails, as well as environmental variables, in 100-m2 lots located in forests and open habitats in the Russian Altai Mountains and their northern foothills. Climate was identified as the strongest predictor of alpha diversity across all taxa, with temperature being positively correlated to number of species of vascular plants and land snails and negatively correlated to that of bryophytes and macrolichens. Factors important for only some taxa included precipitation, soil pH, percentage cover of tree layer and proportion of grassland areas in the landscape around plots. These results, combined with the high degree of similarity between the current Altai biota and dry-cold Pleistocene ecosystems of Europe and northern Asia, suggest that vascular plant and land snail alpha diversity was low during cold phases of the Pleistocene with a general increase following the Holocene climatic amelioration. The opposite trend probably existed for terricolous bryophytes and macrolichens.
