The background of the workshop was the proposed EU legislation to regulate nutrition and health claims for foods in Europe. This regulation will require the development of a science-based nutrient profiling system in order to determine which foods or categories of foods will be permitted to make nutrition or health claims. Nutrient profiling can also be used to categorize foods, based on an ass...

While non-point nutrient loads are important determinants of biological productivity in Southeastern Piedmont impoundments, productivity can be attenuated by concomitant sediment loads that reduce the biological availability of these nutrients. A biogeochemical model is proposed that explicitly accounts for the effects of sedimentenutrient interactions on multiple components of phytoplankton me...

Intensive fertilization of young spruce forest plantations (i.e. ‘nutrient optimization’) has the potential to meet increasing demands for carbon sequestration and biomass production from boreal forests. However, its effects on biodiversity, other than homogenization ground-layer plant communities, are widely unknown. We sampled ground beetles (Coleoptera: Carabidae) in southern Sweden, within ...
