Ecology of Shallow Lakes (Google eBook)
This book presents a theoretical framework for understanding the dynamics of shallow lake communities as it has evolved over the past years from a combination of empirical studies, experimental work and model analysis. Although, as in most theoretical work, mathematical formulations play a role, the models that are used remain simple and most analyses are graphical rather than algebraic. The book will therefore appeal to workers who do not usually dig deep into theoretical ecology such as lake managers, field biologists and experimentalists. Students of theoretical ecology will also gain from the many real-world applications of topics such as predation and competition theory, bifurcation analysis and catastrophe theory.

Page xviii - Strong inference consists of applying the following steps to every problem in science, formally and explicitly and regularly: 1. Devising alternative hypotheses 2. Devising a crucial experiment (or several of them), with alternative possible outcomes, each of which will, as nearly as possible, exclude one or more of the hypotheses 3. Carrying out the experiment so as to get a clean result 4. Recycling the procedure, making subhypotheses or sequential hypotheses to refine the possibilities that remain,...
Page xviii - The difference between the average scientist's informal methods and the methods of the strong-inference users is somewhat like the difference between a gasoline engine that fires occasionally and one that fires in steady sequence. If our motorboat engines were as erratic as our deliberate intellectual efforts, most of us would not get home for 3 The Breaking of the Circle (Columbia University Press, New York, 1960), p.

Page xvii - So soon as this parental affection takes possession of the mind, there is a rapid passage to the adoption of the theory. There is an unconscious selection and magnifying of phenomena that fall into harmony with the theory and support it, and an unconscious neglect of those that fail of coincidence.
