“Deep, cold Lake Superior is the model for Life in a Lake, an attractive and readable reference on aquatic ecosystems. The volume covers the biotic and abiotic factors in each layer of the lake, and the delicate balance that exists in this ecosystem. The treatment is detailed and complete enough for secondary research, with a reading level that would be comfortable for middle school and motivated elementary students. Maps and insets about specific organisms support the text. Human impacts, from the arrival of the first navigators in the 1600s to today’s efforts to save the lake from logging, exotic species, and pollution, are explained."
