Speciation and dynamics of phosphorus in relation to lake restoration methods
Lake Okaro is a small, warm monomictic lake in the central North Island of New Zealand. It has remained highly eutrophic despite an intensive catchment and in-lake restoration program which commenced in 2003. The program has included the implementation of a constructed wetland, riparian protection, …

Restoring freshwater quality: an integrated environmental, economic and ecosystem services assessment of reducing nutrient loads to Lake Rotorua
… of freshwater urgently requires concerted restoration actions to reverse the decline. Restoration of lakes is impacted by complex relationships of ecosystem responses to management actions, economic constraints, societal pressures and policy contexts. Research in this thesis was aimed at an …

Lacustrine Arcellinida (Testate Lobose Amoebae) as Bioindicators of Arsenic Contamination: A new tool for Environmental Risk Assessment
… of arsenic (As) contamination, especially in lakes. Arcellinida, lacustrine benthic protozoans, have great As-biomonitoring potential that has yet to be exploited by lake restoration initiatives. This research aims to further develop Arcellinida as a robust tool for monitoring As contamination …

Redox cycling of colloidal macro- and micro-nutrients in a monomictic lake
Lakes are more than just water bodies as they play an essential role in the cycling of nutrients and carbon, with impacts at the local and global scale. This study selected Lake Ngapouri, a small monomictic lake in the Waikiti Valley, Taupo Volcanic Zone, New Zealand, which receives a considerable …

Erarbeitung einer P-Bilanz im Rahmen eines Konzeptes zur Sanierung und Restaurierung des Rangsdorfer Sees
Der Rangsdorfer See (A = 2,44 km² , z(max) = 6 m, z(mean) = 1,930 m) im Landkreis Teltow Fläming ist einer von vielen Gewässern in Brandenburg, die derzeit den nach EU-Wasserrahmenrichtlinie geforderten guten Zustand nicht erreichen. Bekanntlich gilt Phosphor für viele Gewässer als der bedeutendste …

The influence of sediment nutrient dynamics on the response of lake ecosystems to restoration and climate change
… of water quality in many freshwater lakes worldwide. Apart from anthropogenic impacts, it is also recognized that climate has a direct influence on lake water temperature, nutrient loads, phytoplankton abundance and chemistry. However, little is known about the potential effects of …
