Do rooted macrophytes increase sediment phosphorus release? date and site could not be delineated..Release rates in this study were affected by a number of factors (plants, site and date). The picture emerging so far is that when rooted macrophytes have a significant effect on phosphorus release they increase it. However the large variability between replic

Meiobenthos communities of some subarctic lakes of Bivalvia positively correlated with primary production of phytoplankton..Oil pollution caused structural changes of communities. Benthic Cladocera and Chironomidae are more vulnerable to the effect of oil pollution. They were only abundant at unpolluted and law-polluted localities of the lake bo

Top-down control in freshwater lakes: the role of nutrient state, submerged macrophytes and water deities of cladocerans to escape predation by vertical migration are less. (4) That the zooplanktomphytoplankton mass ratio per m. is lower and presumably then also the grazing pressure on phytoplankton. (5) That nutrient constraints appear to be weaker, as evidenced by the fact that at a given annual
