Regular ecological investigations usually on a fortnightly basis have been carried out at the Saidenbach Reservoir (SE Germany) and its tributaries since 1975. The data show a sudden decrease in the phosphorus import of over 60% in 1990, resulting in

Summary 1. Long-term data on the meteorology, hydrology, physicochemistry and plankton of a reservoir and its tributaries in SE Germany run from 1976 until now. This dimictic reservoir changed from mesotrophic to eutrophic in the 1970s, remained eutr

The function of hemoglobin (Hb), which is a key protein of many species, was analyzed in Daphnia from the field. Temperature and oxygen content; abundance and composition of phytoplankton; and abundance, body, and clutch sizes of the Daphnia assembla

In two reservoirs of different trophic state, the abundance of autotrophic picoplankton was continuously assessed for 7 and 11 years, respectively. Simultaneously, other important environmental and biotic factors (nutrients, temperature, phyto- and z

Phenology and seasonal succession in aquatic ecosystems are strongly dependent on physical factors. In order to promote investigations into this coupling, methods of characterising annual time series of phytoplankton were derived and applied to a 31-

After the dramatic reduction of the P import into the Saidenbach drinking water reservoir since 1990, an improvement of the trophic state from eutrophic to mesotrophic or even oligotrophic regarding P-concentrations was observed, and corresponding de
