The spatial distribution of communities was examined in estuarine mud flat sediments by the biochemical analysis of the lipids and lipid components extracted from the sediments. Total phospholipid was used as a measure of total biomass, and fatty acids were used as indicators of community composition. Comparisons were made among 2- by 2-m (location) and(More)
It has been suggested in the ecological literature that species may be excluded (or "deleted") from an environment because they do not differ sufficiently from other species in the environment. We develop tests of various deletion hypotheses based on the assumption of a random distribution of species sizes. The results provide information on the behavior of(More)
Earlier, a sensitive turbidimetric method was reported (H.A. McKenzie and F.H. White, Jr. Biochem. Int. 14, 347-356, 1987), with which evidence was found for weak lysozyme-like activity in alpha-lactalbumin (alpha-LA) against Micrococcus luteus. Alternative methods have been developed for the further study of trace cell-lytic activity, and the results are(More)
Character displacement is an important concept in ecology which has been surrounded by controversy due largely to a lack of clearly stated hypotheses and statistical tests. Existing tests implicity assume random species sizes estimated without error--a random-effects model. We introduce the log-uniform distribution for species sizes and show that it has(More)
