Effects of Low Doses of Herbicides on Different Endpoints in the Life Cycle of Non-target Terrestrial Plants.

abstract：:It is generally assumed that as long as the majority of species experiences no direct adverse effects attributable to a single substance (i.e., potentially affected fraction [PAF] <5%), no significant structural or functional effects at the community level are expected to occur. Whether this assumption holds for mixed...
