摘要: Five oxbow lakes of the Łyna River, located in an agricultural area, were studied seasonally 2005 and 2008. The EPT index (abundance Ephemeroptera, Plecoptera Trichoptera larvae), as well their proportion to Chironomidae indicated that groups sensitive environmental conditions occurred at low abundance relation different hydrological types lakes. Family Biotic Index, Biological Monitoring Working Part adapted Polish Average Score Per Taxon (ASPT) revealed water quality regardless level connectivity. In turn, indices biodiversity Margalef (d) probability interspecific encounters good or satisfactory quality. pH correlated positively with total aquatic invertebrates, while lower macroinvertebrate was observed turbid waters lentic oxbows a high content dissolved solids. Canonical correspondence analysis showed conn...
