Organisms studied

Methods:	Nutrient concentrations in mosses (Hygrohypnum spp. and Schistidium agassizii) were monitored in P fertilized riffles in the Kuparuk River in 1995. Two samples per site were collected by combining 4-5 small clumps of each taxa from a 5 m^2 area in each riffle, rinsing thoroughly, and drying to a constant weight at 65 C. Samples were ground in a Wiley Mill to pass a #30 mesh and digested at 425 C with peroxide, potassium sulfate, copper sulfate, and hydrochloric acid. Digested samples were diluted with deionized water and analyzed for total phosphorus and nitrogen with an autoanalyzer. National Institute of Standards and Technology peach leaves were digested and analyzed to ensure the efficiency of digest and analytical procedures. Reference Citations: Bowden, W.B., J.C.
