We would be poor ecologists indeed if we did not believe that the principles of ecology apply to all facets of the world around us wcologia all aspects of human endeavor. Whatever progress is made, ecology will remain a meeting-ground for the naturalist, the experimentalist, the field biologist and the mathematical modeler. Different chapters of this book contain different proportions of descriptive natural history, physiology, behavior, rigorous laboratory and field experimentation, careful field monitoring and censusing, and mathematical modeling a form of simplicity that it is essential to seek but equally essential to distrust.

Parte 1 de We believe that all ecologists should to some extent try to combine all these facets. English Choose a language for shopping. Unlike some other sciences, the subject matter of ecology is apparent to everybody: B —dc22 Finally, perhaps the most profound alteration to the construction of this book in its fourth edition is that the revision has been the work of two rather than three of us.

Nineteen years on, we have tried to capture in our cover design both how much and how little has changed. It must deal explicitly with three levels of the biological hierarchy — the organisms, the populations of organisms, and the communities of populations — and, as we shall see, it ignores at its peril the details of the biology of individuals, or the pervading influences of historical, evolutionary and geological events.

These, we hope, will serve a number of purposes. For this edition, though, we have also added a brief summary to each chapter, that, we hope, may allow readers to either orient and prepare themselves before they embark on the chapter or to remind themselves where they have just been. Hence, while the remaining chapters are still largely about the principles themselves rather than their application, we believe that the wholeof this book is aimed at improving preparedness for addressing the environmental problems of the new millennium.

It feeds on advances in our knowledge of biochemistry, behavior, climatology, plate tectonics and so on, but it feeds back to our understanding of vast areas of biology too.

But 19 years ago it seemed acceptable for ecologists to hold a comfortable, objective, not to say aloof position, in which the animals and plants around us were simply material for which we sought a scientific understanding.

The Preface to the first edition began: First edition published by Blackwell Publishing Ltd Second edition published Third edition published Fourth edition published Finally, perhaps the most profound alteration to the construction of this book in its fourth edition is that the revision has been the work of two rather than three of us. Hence, while the remaining chapters are still largely about the principles themselves rather than their application, we believe that the wholeof this book is aimed at improving preparedness for addressing the environmental problems of the new millennium.

The challenge of ecology is to develop an understanding of very basic and apparent problems, in a way that recognizes this uniqueness and complexity, but seeks patterns and predictions within this complexity rather than being swamped by it.

For this edition, though, we have also added a brief summary to each chapter, that, we hope, may allow readers to either orient and prepare themselves before they embark on the chapter or to remind themselves where they have just been. Now, we must accept the immediacy of the environmental problems that threaten us and the responsibility of ecologists to come in from the sidelines and play their full part in addressing these problems.
