Emphasizing forms found in the formerly glacial region of northeastern North America, Colburn offers an overview of the natural history, ecology, and conservation of the small, transient, biologically dynamic pools that appear in low-lying areas particularly in spring, then typically disappear as the seasons progress. A lengthy appendix lists and describes the fauna found in such pools. Of interest to students and stewards of freshwater resources and biological diversity—land owners, naturalists, teachers, researchers, conservationists, resource managers, and policymakers. Colburn is an aquatic ecologist on the staff of Harvard Forest, Petersham, MA. Annotation ©2004 Book News, Inc., Portland, OR
