โœฆ Synopsis

Certain chemical constituents (NO,-N, bio-available P, Ca, Na, K, Mn, Cu, Co and organic matt)er) together with pH, Eh and clay content of surface sediments a t various depths of the overlying water in Lake Bhim Tal were examined during 1977-1978. I n addition, NH:,-N and dissolved oxygen a t the mud-water interface (water immediately above the sediments) were measured.

The values of Eh, pH and NOC1-N in the sediments showed a negative relationship with water depth and positive relationship with dissolved oxygen a t the interface. The other variables of the sediment were positively related to water depth and negatively related to dissolved oxygen a t the interface. Organic matter, K, Na and Ca showed positive relationship with the amount of clay while the cations (K, Na, Ca) and trace metals (Cu, Mn, Co) showed a positive relationship with the amount of organie matter in the sediments.

Certain parameters of the zoobenthos community structure, viz., population density, species richness, diversity, dominance and similarity indices in the inshore area (0-1 m stratum) of Lake Naini Tal were examined during 1978-1979. Significznt changes in community structure were found both in space

The phytoplankton community in Lake Khurpatal (Kumaun Himalya), India, was analyzed in relation to physico-chemical variables. Phytoplankton biomass ranged from 2.7 to 20.0 g m-3 in the euphotic zone of the lake. Dinoflagellates monopolized the algal community with a mean annual contribution of 94.5
