β¦ Synopsis
A model for several algal species which compete both for light and for nutrients, and which are also subject to settling and diffusion, is considered. The settling speeds and diffusion coefficients are assumed to be small, in a sense to be made precise later, and a singular perturbation argument is used. In certain cases vertical segregation of the algal species is observed, and the mechanism for this is interpreted biologically.

We explore the effects of asymmetric competition for light on the outcome of interspecific competition in simple models of resource competition. The models assume that species only differ in their allocation of resource to roots and photosynthetic tissues. Previous studies, which assume symmetric co
Four indoor model ecosystems with natural plankton communities have been run. Two of the systems are exposed to artificial photosynthetic active radiation (PAR, 20 W mm2 for 16 h per day) and UV-B radiation ( = 0.64 W me2 for 6 h per day), while the other two are exposed to PAR only. Photosynthesis,
