Geochemical focusing and sequestration of manganese during eutrophication of Lake Stechlin (NE Germany)
Eutrophication of Lake Stechlin leads to changes in the sediment by an intensification of internal matter cycles. The reductive dissolution of Mn in shallow areas and the precipitation result in the fixation of Mn as rhodochrosite in the sediment below 56 m depth. Geochemical Mn focusing indicates oxygen-free conditions in deep water and can be used to reconstruct former environmental conditions.

Long-term warming destabilizes aquatic ecosystems through weakening biodiversity-mediated causal networks
Climate change destabilizes aquatic ecosystems through weakening the interactions between species richness and biomass of phytoplankton and the chemical and physical environmental factors. This is the conclusion of a study on long-term data series of 10 aquatic ecosystems using the convergent cross mapping (CCM) method.
