The highest uptake rate was by individuals of each species with large capitula and a high number of ion exchange sites, i.e. lawn species ( S. pulchrum , S. fallax , S. papillosum and S. magellanicum ). On a dry‐mass basis, the most effective species were the hummock species ( S. fuscum and S. rubellum ), even though these species have a low dry mass. Hummock species, which occur in high densities and have high potential N‐uptake rates on a dry‐mass basis, were the most effective species in retaining available nitrogen.Read More
