This book is a general text covering both basic and applied aspects of freshwater ecology and serves as an introduction to the study of lakes and streams. Issues of spatial and temporal scale, anthropogenic impacts, and application of current ecological concepts are covered along with ideas that are presented in more traditional limnological texts. Chapters on biodiversity, toxic chemicals, extreme and unusual habitats, and fisheries increase the breadth of material covered. The book includes an extensive glossary, questions for thought, worked examples of equations, and real-life problems.
