Abstract

A field study was carried out during 3 years in Idaho, USA, to investigate the combined influence of simulated herbivory (defoliation through clipping of 40 or 80% of above-ground biomass) and plant competition on flowering and seed production of Euphorbia esula in rangelands. Defoliation had greater detrimental influence than plant competition on E. esula reproduction. Reduction in flowers and seed production increased (non-significantly) with the level of defoliation.
