R.D.W. after N. furcata subsp. megacarpa and not N. flexilis (L.) Ag. as previously reported. Internodal cell length was found to increase with depth, pigment content changed with depth, biomass distribution had decreased since an earlier study, primary productivity was low and was associated with the depth of maximum biomass and pigment content, and the furcations of the branchlets increased in shallower water.vii, 68 leavesapplication/pdfenIn CopyrightLD5655.V855 1988.J478CharophytaMountain Lake (Va)Thesis
