Previous research indicated that rootmats may be important habitats for aquatic invertebrates and may have a distinct invertebrate composition compared to other instream habitat types. The objective of this study was to examine the invertebrate communities inhabiting rootmats of eight common woody riparian species in Cuyahoga Valley National Park, Ohio (CVNP). I collected 47 rootmat samples from pools across 10 CVNP streams. Coarse particulate organic matter, root morphology, and physiochemical variables were measured to characterize the local habitat at each location. Invertebrate community indices, multivariate techniques and univariate techniques were used to investigate the role of rootmats as habitat and determine whether any associations existed between invertebrate communities and eight woody riparian species. Additionally, invertebrate communities of rootmats were compared to adjacent riffles for eight sites. </p><p>A total of 138 taxa were collected from rootmats across all woody species. Most (59%) of the taxa were gathering collectors and this suggests that fine particulate organic matter may be a dominant food source within or near rootmats. Additionally, 15% of the captures were predators, while scrapers, shredders and filtering collectors were present in similar proportions (8-9% each). Paratanytarsus dissimilis was the most abundant organism across the samples at nearly 250 organisms m-2. Other abundant taxa were Chironomidae (midges), Calopteryx maculata (damselfly), Caecidotea communis (isopod), Stenelmis sp. and Dubiraphia bivittata (riffle beetles). Invertebrate diversity, species composition and functional feeding guilds differed among certain tree species. Specifically, rootmats of two willow species (Salix interior and Salix nigra) were consistently similar to each other, and different from rootmats of Carpinus caroliniana, Fraxinus pennsylvanica, and Acer saccharum. Additionally, invertebrate species composition was different in adjacent rootmat and riffle habitats, but the habitats were similar in terms of diversity and abundance.</p> 2009-09-10 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1245417333 http://rave.ohiolink.edu/etdc/view?acc_num=osu1245417333 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
