## Abstract The factors influencing the diversity, species composition and abundance of phytoplankton in 21 lakes in the Canadian arctic and subarctic were determined between 1975 and 1978. The maximum number of species (60–75). and highest diversity indices (1. 6–1. 9). were recorded from the most
The factors influencing the density, diversity and species composicion of benthic invertebrate communities in 20 lakes in the Canadian arctic and subarctic were determined during 1975, 1976 a n d 1977. Despite small differences in nutrient and phytoplankton levels among the lakes, there was a strong
