Abstract
The paper reports the impact of a sharp artificial enrichment of the a vailable phosphorus in a small, acidic and oligotrophic corrie lake an d its effects upon the phytoplankton supported. Annual average chlorop hyll increased tenfold within two years, from similar to 1.2 to 12.6 m u g chi a l(-1), but the species represented by large populations are the same as previously. Chrysophyte species, however, make up a smalle r fraction of the total crop.
