The state of the environment of the Loosdrecht lakesdescribed as a series of phases. One of those phases, the status around 1940, has been used as an ecological reference system..By means of a graphical presentation technique, the so-called ‘AMOEBE-approach’, the state of the environment of the Loosdrecht lakes has been visualized. Thirty-two ecologi

Phosphorus in the sediment of the Loosdrecht lakes and its implications for lake restoration perspec 0.8 mg m. d. agrees well with the average phosphorus retention in the lake. This indicates that sediment burial and diagenesis are unimportant mechanisms for withdrawing phosphorus from the nutrient cycle..Between 1982 and 1991 the total phosphorus content of the upper 2 cm of the sediment decrease

The dynamics and role of limnetic zooplankton in Loosdrecht lakes (The Netherlands). Among about 20 genera and 40 species of rotifers the important ones are: . and .. The rotifers usually peak in mid-summer following the crustacean peak in spring. The mean annual densities of crustaceans decreased during 1988–1991. Whereas seston (<150 .m) mean mass in the lake increased since 198
