Substratum-production relationships in net-spinning caddisflies (Trichoptera) in disturbed and undisturbed hardwood catchments. Gurtz, M. E. Journal of North American Benthological Society, 1986. Paper abstract bibtex The effect of substratum on production of two species of net-spinning Trichoptera was examined in two second-order Southern Appalachian streams: Hugh White Creek, a reference stream draining an undisturbed hardwood catchment, and Big Hurricane Branch, which drains a catchment that was clear cut during the first six months of the study. Surber samples were collected monthly for 21 months in four common substrata in each stream: moss-covered rock face, cobble riffle, pebble riffle, and sandy reach. Both species showed distinct substratum preferences. Abundances and production were significantly higher in rock face \textgreater cobble riffle \textgreater pebble riffle \textgreater sandy reach in both streams. Differences in production between streams may be related more to geomorphic differences between streams than to effects of logging on these two species.
