Abstract:
The chemical composition and biotic structure were studied in ecotonal zones
of six trophically differentiated lakes in the region of Polesie Lubelskie
(Eastern Poland). High
qualitative and quantitative differentiation of zoocenoses (zooplankton and
zoobenthos) usually occurred in each ecotonal zone of every lake studied. The highest diversity
occurred among microinvertebrates (zoopsammon and zooplankton). |
