Diatoms and Lake Acidity

John P. Smol is a professor in the Biology Department at Queen's University (Canada), with a cross-appointment at the School of Environmental Studies. He co-directs the Paleoecological Environmental Assessment and Research Lab (PEARL). Professor Smol is co-editor of the Journal of Paleolimnology and holds the Canada Research Chair in Environmental Change.

'This book should be read by anyone interested in current methods, data, and conclusions in this area of investigation. Diatoms and Lake Acidity is recommended reading for anyone wishing to assess current understanding of lake acidification, and especially recommended for those who wish to improve it.' Bioscience, 37 (1987) 'Researchers and advanced students of lake acidification, paleolimnology, and phycology will find this book a valuable addition to their libraries.'
