Decrease of both zooplankton and zoobenthos species richness and a trend toward decrease of their biomass with the salinity increase was recorded in the hypersaline lakes of Crimea. The most of structural and functional characteristics of macrobenthos is positively correlated with abiotic and biotic characteristics of those lakes. Abundance, biomass, productivity of macrobenthos and ration of non-predating macrozoobenthos decrease with salinity increase, while they increase with the depth and growth of amount of chlorophyll a and primary production. Macrozoobenthos portion in the total zooplankton and macrozoobenthos biomass decreases with both salinity and depth increase. Zooplankton community is less controlled by abiotic factors as compared to macrozoobenthos, while the former's species number significantly decrease with salinity increase. Effect of salinity on zooplankton biomass is slightly significant, unlike that of macrozoobenthos. Comparison of total amount of rations of zooplankton and macrozoobenthos with amount of primary production indicates intense trophic interactions in the lakes under study.
在克里米亚的超咸水湖中，浮游动物和底栖动物的物种丰富度均有所下降，且随着盐度升高，它们的生物量呈下降趋势。大型底栖动物的大多数结构和功能特征与这些湖泊的非生物和生物特征呈正相关。随着盐度升高，大型底栖动物的丰度、生物量、生产力以及非捕食性大型底栖动物的比例会下降，而随着深度增加以及叶绿素a含量和初级生产力的增长，它们会增加。在浮游动物和大型底栖动物的总生物量中，大型底栖动物的比例会随着盐度和深度的增加而下降。与大型底栖动物相比，浮游动物群落受非生物因素的控制较小，而随着盐度升高，前者的物种数量会显著减少。与大型底栖动物不同，盐度对浮游动物生物量的影响不太显著。将浮游动物和大型底栖动物的总摄食量与初级生产量进行比较表明，在所研究的湖泊中存在强烈的营养相互作用。
