EXPERIMENTAL ECOLOGY OF DRYAS OCTOPETALA ECOTYPES: RELATIVE RESPONSE TO COMPETITORS
S ummary A competition experiment was performed to determine the relative competitive abilities of fellfield and snowbed ecotypes of Dryas octopetala L. under conditions of high nutrients, high light, and high water availability. Pots were designed to allow the effects of root competition and shoot...
