New edition of an introductory text in liminology. Wetzel, who has published extensively on the subject, argues that apart from the structure of water and a few physical properties, aquatic ecosystem structure, energy flow, and productivity are regulated by biogeochemical cycling. Also, he presents data supporting conceptual relationships among biota and the environment, and maintains that regulatory generality prevails across the individual species and diversity of processes, especially concerning regulation of metabolic rates among different communities. The 26 chapters combine lacustrine, reservoir, and running water limnolgy. Illustrated with b&w diagrams and charts.

This newest edition is marked not only by substantial reworking, updating, and addition but also by the maturation of the author's understanding of freshwater ecosystems, and understanding that has been amassed from years of study and analysis of his own and others' research. ...the author's ability to put the tremendous array of subjects into context is nothing short of remarkable. ...this book is a timely and masterful revision, and it should be on the shelf and in the classroom of every practicing freshwater algal ecologist and limnologist.
