Is ecology at a crossroad? After three decades of rapid, though somewhat anarchic development, many ecologists now are beginning to ask this question. They have the feeling of no longer belonging to a unified and mature scientific discipline. Many of them claim to be mere empiricists, whereas others are proud to be considered theoreticians. Each side has its own journals and holds its own specialists' meetings, tending to disregard the achievements of the other. The communication gap between the two schools is quickly widening, to the detriment of both. To make things worse, the word "ecology" now has a different meaning for the professional biologists and the general public. Ecology is still considered as a creditable (though rather "soft") scientific discipline by the former, whereas it is perceived as a new, non-conformist political philosophy by the latter. Empirical ecologists are fundamentally naturalists who enjoy the immense complexity of the natural world and devote their lifetimes to the description of the many adaptive characteristics--morpholog ical, biological, or behavioral--of the hundreds of thousands of species sharing the earth with us. They generally are ignorant of, if not allergic to, the use of any mathematical representation of living phenomena. They' feel that ecological theory is rapidly becoming a mathematical game that has lost any contact with the "realities of life.

The environment is considered the surroundings in which an organism operates, including air, water, land, natural resources, flora, fauna, humans and their interrelation. It is this environment which is both so valuable, on the one hand, and so endangered on the other. And it is people which are by and large ruining the environment both for themselves and for all other organisms. This book reviews the latest research in this field which is vital for everyone.

Represents the outcome of a joint meeting of the Landscape Institute and the British Ecological Society at which the whole new relationship between ecology and design in landscape was explored by leading ecologists and landscape architects from a wide range of countries.

The 1980 eruption of Mount St. Helens caused tragic loss of life and property, but also created a unique opportunity to study a huge disturbance of natural systems and their subsequent responses. This book synthesizes 25 years of ecological research into of volcanic activity, and shows what actually happens when a volcano erupts, what the immediate and long-term dangers are, and how life reasserts itself in the environment.
