The Water Framework Directive (WFD) is a pioneering piece of legislation that aims to protect and enhance aquatic ecosystems promote sustainable water use across Europe. There growing concern the objective good status, or higher, in all EU waters by 2027 long way from being achieved many countries. Through questionnaire analysis almost 100 experts, we provide recommendations WFD monitoring assessment systems, improve programmes measures further integrate with other sectoral policies. Our...
Unlike in land plants, photosynthesis many aquatic plants relies on bicarbonate addition to carbon dioxide (CO2) compensate for the low diffusivity and potential depletion of CO2 water. Concentrations vary greatly with catchment geology. In this study, we investigate whether there is a link between these concentrations frequency freshwater possessing use trait. We show, globally, that plant species trait increases concentration. Regionally, however, reduced at sites where concentration...
Summary The spatial organisation of biotic communities derives from factors operating at a wide range and temporal scales. Despite strong scientific evidence prevalent control community composition in freshwater ecosystems, local environmental are often considered as the main drivers change. Furthermore, taxonomic approaches most frequently used, few studies have compared relative importance regional trait versus stream ecosystems. Using spatially dense data set covering all sizes lowland...
1. The objective of the present study was to examine how physical stream environment in regulated and unregulated lowland streams affects diversity distribution macrophyte communities. We analysed abundance, composition macrophytes, together with parameters, seven unshaded Danish reaches. 2. Total coverage similar streams, but species richness Shannon were higher streams. Overall, we found fifty‐two different reaches sixty‐two spatial macrophytes on bottom more heterogeneous 3. positive...
Phosphorus loss from bank erosion was studied in the catchment of River Odense, a lowland Danish river basin, with aim testing hypothesis whether stream banks act as major diffuse phosphorus (P) sources at scale. Furthermore, study aimed analyzing impact different factors influencing and P such order, anthropogenic disturbances, width uncultivated buffer strips, vegetation strips. A random stratified procedure geographical information system (GIS) used to select two replicate reaches...
Summary Restoration of river hydromorphology often has limited detected effects on biota. One frequently discussed reason is that the restored length insufficient to allow populations develop and give room for geomorphological processes occur. We investigated ten pairs sections which one was a large project involving long, intensively section represented smaller restoration effort. The effect quantified by comparing each an upstream non‐restored section. sampled following response variables:...
