1. The role of freshwater phytoplankton in the global carbon cycle
Sammanfattning : Water flowing through the landscape transports chemical substances including carbon. Along the way from upland soils to the ocean, carbon is transformed from organic carbon into inorganic carbon and vice versa. One such carbon transformation process is the uptake of carbon dioxide (CO2) from the water phase by phytoplankton. LÄS MER
2. The significance of sediment resuspension in lakes
Sammanfattning : .... LÄS MER
3. Carbon Dioxide in Inland Waters : Drivers and Mechanisms Across Spatial and Temporal Scales
Sammanfattning : 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. LÄS MER
4. Causes and consequences of Gonyostomum semen blooms
Sammanfattning : 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. LÄS MER
5. Predictions Within and Across Aquatic Systems using Statistical Methods and Models
Sammanfattning : Aquatic ecosystems are an essential source for life and, in many regions, are exploited to a degree which deteriorates their ecological status. Today, more than 50 % of the European lakes suffer from an ecological status which is unsatisfactory. LÄS MER
