    Plant species richness in continental southern Siberia: effects of pH and climate in the context of the species pool hypothesis.

  • Original language description

    Aim: Many high-latitude floras contain more calcicole than calcifuge vascular plant species. The species pool hypothesis explains this pattern through an historical abundance of high-pH soils in the Pleistocene and an associated opportunity for the evolutionary accumulation of calcicoles. To obtain insights into the history of calcicole/calcifuge patterns, we studied species richness-pH-climate relationships across a climatic gradient, which included cool and dry landscapes resembling the Pleistocene environments of northern Eurasia. Location: Western Sayan Mountains, southern Siberia. Methods: Vegetation and environmental variables were sampled at steppe, forest and tundra sites varying in climate and soil pH, which ranged from 3.7 to 8.6. Species richness was related to pH and other variables using linear models and regression trees. Results: Species richness is higher in areas with warmer winters and at medium altitudes that are warmer than the mountains and wetter than the lowlands

    Druhová bohatost rostlin na kontinentální jižní Sibiři: vliv pH a klimatu v kontextu species pool hypotézy.

  • Czech description

    pH na kontinentální jižní Sibeři je silně negativně korelováno se srážkami a druhová bohatost je určována protisměrnými účinky těchto dvou proměnných. Druhová bohatost se zvyšuje s pH, pokud půda není příliš suchá. U suchých půd je pH vysoké, ale druhovábohatost se snižuje vlivem stresu suchem. Vztah druhové bohatosti a pH je proto v bezlesé vegetaci unimodální. Na nejsušších půdách nerostou stromy, což má za následek, že u lesů je vztah pH/druhová bohatost pozitivní. Pokud je současná druhová bohatostdůsledkem velikosti species pool, zdá se, že v minulosti byla běžná stanoviště s nižšími srážkami a mírně kyselými až neutrálními půdami.
