EVALUATION OF THE RELATIONSHIP BETWEEN STREAM MICROHABITATS AND TAXA TRAITS IN PIEDMONT STREAMS IN NORTH CAROLINA

Stream habitat quality and benthic macroinvertebrate diversity are negatively impacted by urbanization. To better understand urbanization impacts, we quantified which components of habitat diversity were most important for controlling benthic macroinvertebrate taxa and trait richness and diversity by quantifying the relationship between these metrics and microhabitats at the reach level in 10 streams with high habitat quality. We collected benthic macroinvertebrates from 7 microhabitats (riffles, root wads, leaf packs, woody debris, undercut banks, backwater, and sandy areas) to correlate taxa and their traits with each microhabitat. Riffles were the most diverse microhabitat in terms of taxa (44) and diversity (2.7). Leaf packs, root wads, and woody debris also supported abundant taxa (29, 21 and 19 respectively) and good diversity (2.7, 2.6 and 2.3). Sand and undercut banks were less productive habitats with fewer taxa (8 and 10) and lower diversity (1.5 and 2.1). Indicator species analysis indicated that some taxa and traits were specific to specific microhabitats while others were common among the microhabitats. By correlating the taxa and traits with specific microhabitats, we can better evaluate the impact of urbanization on benthic macroinvertebrate communities and improve restoration design.
