| The plant and animal health care strategy in organic farming strengthensagro-biodiversity, protects the environment as well as animal and human health. In addition to fully exploiting preventive options, the use of external inputs such as plant protection products, fertilisers or veterinarymedicinal productsis allowed to prevent inacceptable losses in productivity or animal suffering. However, external inputs need to comply with organic standardsas well as European legislationand aretherefore carefully evaluated before any decision on acceptance is taken.Organic farming systems should aim at reducing dependency on off-farm fertilisers to the lowest feasable level to ensure closed nutrient cycles and avoid nutrient leakage and contamination.

| New species arise through the evolution of reproductive barriers between formerly interbreeding lineages. Yet, comprehensive assessments of potential reproductive barriers, which are needed to make inferences on processes driving speciation, are only available for a limited number of systems. In this study, we estimated individual and cumulative strengths of seven prezygotic and six postzygotic reproductive barriers between the recently diverged taxa Silene dioica (L.) Clairv. and S. latifolia Poiret using both published and new data. A combination of multiple partial reproductive barriers resulted in near‐complete reproductive isolation between S. dioica and S. latifolia, consistent with earlier estimates of gene flow between the taxa. Extrinsic barriers... |
