Description :

In its third edition, this classic textbook is thoroughly updated with a series of carefully designed and tested field and laboratory exercises representing the full scope of limnology. Limn logical Analyses covers the physical, chemical, and biological characteristics of standing and running waters, and provides students with a solid foundation in this complex multidisciplinary field of ecology. The book illustrates accepted standard methods as well as modern metabolic and experimental approaches and their research applications, step-by-step exercises cover, at several levels of complexity, topics such as:
- major physical components of lakes and streams;
- important mineral and organic nutrients;
- cycling of organic matter;
- bacterial and fungal metabolism;
- benthic fauna;
- primary productivity of phytoplankton;
- protestant and zooplankton feeding and growth;
- quantitative methods in biotic analyses;
- diurnal changes;
- experimental manipulation of model ecosystems;
- effects of sewage outfall and other human activities;
- whole ecosystem and community analyses..
Each exercise is preceded by an introductory section and concludes with questions for the student and a selection of suggested readings. Instructors and students of limnology will value Limn logical Analyses for its highly structured, concise presentation and its research oriented approach that invites active participation. The methodology presented here will also be useful to aquatic resource managers, pollution and water-quality researchers, and all biologists studying the response of aquatic organisms to environmental changes.
