21. Lake Dissolved Organic Matter Quantity and Quality : Variability across Temporal and Spatial Scales
Abstract : Surface waters receive large amounts of dissolved organic matter (DOM) via runoff from land. The DOM is rich in organic carbon that serves as an energy source for the aquatic biota. During uptake of this energy, aquatic organisms mineralize organic carbon. READ MORE

22. Causes and consequences of Gonyostomum semen blooms
Abstract : Aquatic ecosystems provide essential ecosystem services, but are also highly vulnerable to global change. Climate change, eutrophication and browning, for example, collectively drive the increase of harmful algal blooms in freshwaters. READ MORE

24. Carbon Dioxide in Inland Waters : Drivers and Mechanisms Across Spatial and Temporal Scales
Abstract : Inland waters are an essential component of the global carbon cycle as they are very active sites for carbon transformation processes. Much of this carbon is transformed into the greenhouse gas carbon dioxide (CO2) and emitted into the atmosphere. READ MORE

25. Diversity and Ecosystem Functioning : Redundancy and Resilience in Freshwater Bacterial Communities
Abstract : Bacteria are immensely diverse and hold key-positions in essentially all biogeochemical cycles. In freshwater ecosystems, bacteria degrade and mineralize organic compounds, linking the pool of dissolved organic matter to higher trophic levels. READ MORE
