The responses of littoral invertebrates to eutrophication-linked changes in plant communities

摘要: The decay of submerged macrophytes in lakes high trophic level drastically limits the extent habitat available to littoral invertebrates. loss can be partially compensated by growth filamentous algae. Our results show that macroinvertebrates typically associated with as well planktonic crustaceans and rotifers occurred within algal mats at densities. Aggregations algae are usually short-term, frequent appearances disappearances. rate colonization invertebrates is rapid. In locations a degree water exchange, animals colonize both living decomposing similar rate, but sheltered habitats, colonized smaller number animals. Comparison was made between occurrence invertebrate macrofauna on Chara spp., Potamogeton perfoliatus, P. lucens Myriophyllum spicatum several lakes. Although these differ visibly morphology phenology, composition during summer more closely state lake than plant species.
