Calcium intolerance of fen mosses: physiological evidence, effects of nutrient availability and successional drivers

Popis výsledku v původním jazyce

Our results suggest that calcium toxicity in calcifugous bryophytes is caused by insufficient control over the balance of intracellular Ca2+ uptake/efflux. Cell-wall cation-exchange sites of living mosses remain unsaturated with Ca2+ even in calcareous solutions, contradicting the proposed inhibitory effect of Ca2+-oversaturation on cell-wall expansion and monovalent cation uptake. Growth and biomass accumulation of brown mosses was highest in alkaline fen waters, but they could also survive and germinate in poor-fen waters. Calcium-tolerant sphagna survived along the entire poor?rich gradient, but their growth was inhibited by calcium bicarbonate. The three most obviously expanding sphagna produced protonemata even under calcareous conditions. Flowingbut not stagnant alkaline fen waters were toxic for calcifugous sphagna, the strongest competitors in poor-fen waters.
