Abstract

In various biotopic groups of invertebrates of small rivers, the species richness and nematode abundance vary. Periphyton is poorer than meiobenthos. Along with common species, a number of worms are found only in biofouling or only in meiobenthos. A significant increase in species richness, diversity of ecological groups, and abundance of worms in meiobenthos and periphyton of small rivers is observed in zones contaminated with organic substances of anthropogenic and zoogenic origin. The biocenotic and functional role of nematodes in these groups depends to a higher extent on the level of food availability than on a number of other environmental factors that limit their development.

雷宾斯克水库支流Meioententos和线虫的线虫

摘要

在小河流无脊椎动物的各种生物群落中，物种丰富度和线虫丰度各不相同。骨phy比麦角尾藻差。与常见物种一起，仅在生物污染或仅在生物底栖动物中发现了许多蠕虫。在被人为和动物源性有机物质污染的地区，小河的中底栖动物和附生植物中物种丰富度，生态群多样性和蠕虫数量显着增加。在这些人群中，线虫的生物活性和功能作用在很大程度上取决于食物的供应水平，而不是许多其他限制其发展的环境因素。
