The European Water Framework Directive prescribes that the development of a river assessment system should be based on an ecological typology taking the biological reference conditions of each river type as a starting point. Aside from this assessment, water managers responsible for river restoratio
Temperature is one of the most important factors affecting the life history characteristics and biogeography of aquatic oligochaetes in the family Naididae (both the tubificoid Naididae and the Naididae s.str. species). To understand the effect on oligochaetes of climate change in The Netherlands, t
A central goal in monitoring and assessment programs is to detect change early before costly or irreversible damage occurs. To design robust early-warning monitoring programs requires knowledge of indicator response to stress as well as the uncertainty associated with the indicator(s) selected. Usin
A central feature of the European Water Framework Directive are the reference conditions. The ecological quality status is determined by calculating the distance between the present situation and the reference conditions. To describe reference conditions the natural variation of biota in pristine wa
