Eriophorum angustifolium (Cyperaceae) is a pioneer clonal sedge colonizing bare peat surface of harvested peatlands in central Europe. It forms circular patches of densely aggregated ramets, followed by central die-back and ring formation as circles develop. This study experimentally tested the importance of inter-ramet competition, interference with litter, soil nutrient depletion, and architectural constraints for radial clonal spread and ring formation process. We suggest that processes of nutrient foraging and utilization are responsible for development of circular patches of E. angustifolium in the harsh environment of cut-away peatland.

Studovali jsme růst u klonální rostliny Eriophorum angustifolium ve specifických podmínkách odteženého rašeliniště Soumarský most na Šumavě. Pomocí několika pokusů jsme zjistili, že růst je pravděpodobně řízen dostupností živin N a P.
