Reach-Scale Effects of a Stream Logjam on Benthic Macroinvertebrate Community Composition
MetadataShow full item record
Logjams are accumulations of fallen wood that span the width of a stream or river. They offer refuge from high-velocity waters and provide stable surfaces for colonization. In addition, they concentrate food resources and create numerous microhabitats. This study was conducted summer 2010 at Cabin Creek in Superior National Forest and examined the richness and proportion of feeding groups and genera in the benthic invertebrate community as a function of distance from a spanning logjam.
