Paleoecological Environmental Assessment and Research Laboratory, Department of Biology, Queen's University, Kingston, Ontario, K7L 3N6 E-mail: smolj@biology.queensu.ca; Tel: (613) 533-6160; Fax: (613) 533-6617 URL: www.queensu.ca/biology/people/faculty/smol.html The research in John Smol’s laboratory focuses on the study of the complex interactions between lake biota and the environment. Paleolimnological techniques are used to reconstruct lake histories because they require an understanding of living algal and invertebrate communities. A variety of other studies dealing with present-day lake systems are also underway including: environmental degradation and recovery, lake acidification and eutrophication, effects of climate change and contaminant transport. Lake sediments are also being used to track past fluctuations in fish and aquatic seabird populations.
