All members of the aquatic food web rely either directly on indirectly on the autotrophic phytoplankton. The distribution and dynamics of phytoplankton groups reflects a number of things: rate of eutrophication, biogeochemical ...

Organic matter (OM) has an important role in lakes as a pH buffer in low alkalinity waters and acting as an energy source for heterotrophic microorganisms. Increasing OM concentrations in lakes have been reported as a ...

Until recently, time consuming and costly manual measurements have been predominating in lake research and monitoring. Usually, this kind of measurements do not provide sufficient temporal and spatial resolution if any. ...

Macrophytes play an important role in lake ecosystems, which provisionally can be divided into an active role consisting of modifying in-lake processes and creating habitat for other groups of biota, and a passive role ...

Phytoplankton is the most important primary producer in the aquatic ecosystems and account for half of all photosynthetic activity on earth, thus creating the base for most aquatic food chains. It also plays key role in ...

About 90% of the organic matter in most aquatic systems is dissolved organic matter (DOM) and the rest forms the pool of particulate organic matter. DOM plays a significant role in the carbon and energy cycle of water ...

Pikeperch, Sander lucioperca (L.), is a pelagic predator, which plays a key role in many inland water bodies of the temperate zone by structuring populations at lower trophic levels (Frankiewicz et al., 1997; Dörner et ...

An understanding of the factors that drive the water quality of large lakes is critical to the protection of such waterbodies. In the present study, the contributions made by riverine nutrient loading, sediment resuspension ...

Despite the considerable percentage of inland waters in the temperate zone land cover, their role in the global carbon balance is not clear and the existing data suggest large type specific differences. Respiratory CO2 ...

In general, it was thought that all primary production is channelled through a classical grazing food web from phytoplankton to zooplankton and finally to fish. However, last decades of studies have shown that this simple ...
