The consequence for the dynamics of plant communities and the main threats to macrophyte occurrence and diversity are discussed. Key concepts: Macrophytes contribute to maintaining key functions and related biodiversity in freshwater ecosystems, and to provide the needs of human societies. Most aquatic ...

This includes molecular, biochemical and physiological aspects of macroscopic aquatic plants as well as the classification, structure, function, dynamics and ecological interactions in plant-dominated aquatic communities and ecosystems. It is an outlet for papers dealing with research on the consequences ...
Furthermore, the authors found that these factors are interdependent such that the effects of nutrients are more pronounced when fish are absent, and the effects of fish are more pronounced when nutrient concentrations are high. The present study is the first to demonstrate that the flux of MeHg...

spiralis + LMC on high endogenous nutrient loading in an urban lake was examined via a 120-d field enclosure experiment. In terms of overlying water nutrient concentration control, pore-water NH₄⁺-N and SRP flux reduction as well as sedimentary P inactivation. The combination of V. ...
(restricted to ion exchangers) as well as TMP was analysed separately in order to find type specific emitters. Tested potential source terms were: distance to closest waste water treatment plant (WWTP), marina, recycling station, mixed water and rain water sewers as well as population density, ...
Food production occupies ~40% of earth’s land surface131and understanding the role of agroecosystems in carbon accounting is thus essential. In terms of terrestrial carbon uptake, agroecosystems are often highly productive ecosystems compared to natural ecosystems due to intensified land, nutrient, and...
bottom-up effects of nutrients. These studies suggest that the potential for insect-mediated MeHg flux increases with Hg contamination levels of the environment, but that the realized MeHg flux of individual insect taxa is determined by fish predation and aquatic nutrient concentration....
Dissolved nutrient input from thawing active layer soils during the late season, which is supported by increased major ion concentrations (Supplementary Fig. 10d), may further stimulate increased primary productivity within the stream network37 at a time when water temperatures are at their annual ...
