Seasonal nitrogen dynamics in reed beds (, (Cav.) Trin. ex. Steudel) in relation to productivityt (% DM) of several shoot parts during the height of the growth period..A higher nitrogen percentage of the shoots is correlated with a higher shoot loss and subsequent substitution by branching and tillering during and continuing toward the end of the growth period. A delayed switch from the vegeta

Macrophyte-related shifts in the nitrogen and phosphorus contents of the different trophic levels in years. In this paper we pay special attention to the shifts in relative distribution of nitrogen and phosphorus in the different trophic levels and to the changes in growth limitation of the autotrophs..Despite of the high external nutrient loads to the lake (. 2.4 g P m. y. and 9.6 g N m. y.), the

Functioning of land-water ecotones in relation to nutrient cycling the chemical composition of the open water and the aquatic littoral zone, the composition of phytoplankton, metaphyton and epiphyton. On the basis of these data, the Gooimeer littoral zone is characterized as an eutrophic land-water ecotone dominated by a few species of primary producers. Some data

Some considerations on the functioning of tropical riparian ecotoneshrough the typical and dominant vegetation of the African tropical ecotone wetland, the ‘papyrus’ which is very productive and has considerable adsorbing root surfaces as it spreads out over the water and at the river and lake edges. Because of the twelve-hour light day and high temperatures, the pr
