| Abstract: | Meiobenthos communities of 19 relatively small tundra lakes (area 0.2--320 ha) were studied during summer seasons of 1986--1988 and 1993.The lakes are located 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 0.42--0.92 mg l- 1 and 7.4--6.3 mg l-1. Species composition, number and biomassof meiobenthos were investigated. Relationships between those parameters and environmental and trophic factors were analyzed. Meiobenthosbiomass ranged from 0.003 to 0.911 g m-2 in central zonesof deep lakes and from 0.38 to 17.61 g m-2 in littoral zones. The biomass of littoral Cladocera, Harpacticoida and Nematoda was higher in deep unpolluted mesotrophic lakes. The biomass of Bivalvia positively correlated with primary production of phytoplankton. Oilpollution 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 low-polluted localities of the lake bottom. Highest biomass of meiobenthic Bivalvia occurred in low polluted lakes. Cyciopoida is the most resistant component of meiobenthos communities. Their abundance was highest at most polluted localities. [ABSTRACT FROM AUTHOR] |
