Solidago canadensis impacts on native plant and pollinator communities in different-aged old fields

Secondary succession in former arable fields (i.e. old fields) might be altered by the colonization of invasive alien species, with possible community-wide impacts, hindering the ability of old fields to become species-rich communities. However, the effects of invasive species on local communities have rarely been addressed in the light of secondary succession. Therefore, we studied the impact of the highly invasive Solidago canadensis on plant...
