Diversity and abundance of macroinvertebrates may decrease with human-induced morphological alteration of shoreline and bottom structure. In this study, the spatial variation of macroinvertebrate community structure was explored among different shore types and in relation to habitat characteristics in Hummonselk\u00e4 sub-basin of the clear-water Lake Puruvesi. This study focused on the associations of taxonomic composition and diversity of macroinvertebrates with environmental parameters. The data included over 16 000 individuals of benthic macroinvertebrates, which were sampled from 21 sites with 2\u20133 replicates. The density and diversity of invertebrates were higher at stony and vegetated shores than at structurally simpler sandy shores. The density of individuals and the diversity of benthic invertebrates significantly increased with the increasing percentage coverage of stones and vegetation. Species richness increased with increasing proportion of fine sediments, and density, species richness and diversity of macroinvertebrates correlated positively with periphyton abundance. Based on these and previous results the protection of structural diversity of lake shores has a major importance in maintaining the diversity and functionally healthy lake ecosystems.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2019-11-07T06:29:49Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-11-07T06:29:49Z (GMT).
