Natural and human induced trophic changes in European lowland lakes

The European legislation (WFD) and the IPCC 2008 are both acknowledging the relevance of current and future problems with regard to water quality and quantity. Globally, many lakes are suffering from increased nutrient input (mainly phosphorus) leading to eutrophication. Eutrophication is diminishing ecosystems by causing toxic algal blooms, anoxic events, fish kills, and biodiversity degradation. Assessing the total phosphorus concentrations (TP) through the history of lakes is a key towards understanding the nature of eutrophication processes. In this dissertation the TP dynamics in eight Du... Mehr ...
