Meiobenthos communities of some subarctic lakeslocated in the northeastern region of European Russia. All lakes are separated into deep (with mean depth from 2.0 to 8.0 m) and shallow ones (mean depth is less than 1.5 m). Several lakes were low— or strongly polluted by crude oil. Concentrations of hydrocarbons in lake water were respectively 0.4

Macroinvertebrate communities in relation to submerged vegetation in two ,-dominated lakes Veluwemeer and Lake Wolderwijd. A shift from turbid water with sparse macrophyte cover .towards clear water with a dense cover of submerged vegetation (. spp.) has been observed in the lakes over the past 10 years. Relatively large .meadows (300–500 ha) have recently developed in both lakes. The co

Top-down control in freshwater lakes: the role of nutrient state, submerged macrophytes and water dentrol is more important in shallow lakes than in deep lakes, excepting lakes with a high abundance of submerged macrophytes. The evidence in support is: (1) That at a given epilimnion total phosphorus concentration (TP) the biomass of fish per m. is independent of depth, which means that biomass per
