The Importance of Trophic-Level Interactions to the Abundance and Species Composition of Algae in Laheir biotic communities. Evidence is given to show that in addition to the thesis being correct intuitively, it can be supported by field experiments and by observations even on such well-known lakes as L. Washington, L. Norrviken, L. Trummen, and L. Mendota. Emphasis is on the roles of herbivorous

Vegetation Changes in the Nutrient-Rich Shallow Lake Hjälstaviken, 1931, Öhrn, 1940). The area of lake Hjälstaviken is about 1.4 km.. The reed belts around the lake occupy 1.1 km. and only 30 ha. of the total lake area is open water. Maximum depth is 1.5 m and mean depth is 0.5 m..Life in the lake has changed during the last decades. Aquatic plants were to be fou

A Chemical Model to Describe Nutrient Dynamics in Lakesal equilibrium reactions. Since non-equilibrium processes (or slow reactions) are important too, a model is used where both processes are included. A description of the model equations is given, and results of two calculations are discussed. These two calculations show the importance of total system
