Figure 4.

The temporal competition dynamics expressed as change in the ratio in target species height/(target plant + competitor height). TS, target species. At zero time the first seedlings emerged; height was first measured 22 days later. Triangle: I. glandulifera (target) with I. parviflora (competitor), circle: I. glandulifera with I. noli-tangere, square: I. parviflora with I. noli-tangere. The dashed line represents equal height of both competitors.
