Nitrogen and phosphorus dynamics and retention in ecotones of Lake Titicaca, Bolivia / Peru human activities. The principal objective of this research is to describe and explain the variability in the Andean Altiplano of (a) water, nutrient and sediment fluxes from land and (b) composition, nutrient limitation and other important features of nearshore lake communities, and compare the eff

Microbial decomposition of freshwater macrophytes in the littoral zone of lakesosers and their activity were obtained..Experiments were conducted in the littoral of two lakes with different levels of macrophyte development..Weight loss during 40-60 days of decomposition for fast-decomposing plants was 60-95% and after 365-day of incubation, . L. lost nearly 100% of its initial

Effect of filtering activity of , (Pall.) on the nutrient budget of the littoral of Lake Mikołajskie cycling in periods when its population density was medium or high. The amounts of N and P accumulated in mussel populations at medium density may be similar to those in emergent and submerged macrophytes. However, mussels remove nutrients from cycling matter for a much longer time than do macrophyt

The role of small mammals and birds in transport of matter through the shore zone of lakesimate amounts of food, organic matter and elements ingested and egested during the breeding season by waterfowl. Small mammal densities were estimated, and their movements studied between different patches of a mosaic landscape, including the lake’s shore region. Studies on passerine birds were aime

Transport and retention of matter in riparian ecotonese lotic and edaphic characters overlap at the time of observation. The study site — ‘Oberer Seebach’, near the Biological Station Lunz — and the methods employed are described. Only a surprisingly small fraction (less than 10%) of total imports is transported across the surface ecotones. The driving

Retention of nitrogen and phosphorus in a Danish lowland river system: implications for the export f sediment. The results were used for calculation of the total retention in the river system during two summers (June to August). In addition, the mobilization of nutrients from the stream bottom in autumn 1987 was compared with the export from the watershed..During the study period (June 1987 to Sep
