Among the topics covered by such exercises are: major physical components of lakes and streams; important mineral nutrients; cycling of organic matter; benthic fauna; primary productivity of phytoplankton; quantitative methods in biota analysis; 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 reading. Teachers and students of limnology will value Limnological Analyses for its highly structured, concise presentation. Its research-oriented approach encourages active participation.
