biology department. It should not be lost, however, that through the contributions of Volterra and those who followed his example, ecology was the first sub discipline of biology to become quantitative.

      The writings of Darwin and Wallace clearly influenced the development of ecology; but perhaps even more fundamentally, they also launched the field of evolution. The scientific discipline of ecology has thus been, in some sense, a key node in an ecology of scientific disciplines. From its roots in natural history, it has built partnerships with botany and zoology; with geology and paleontology; with mathematics; and with evolutionary studies, from molecular biology to population genetics and development. It has not ignored physics and engineering along the way, in its need to understand the mechanics of how animals and plants grow and move, or how they capture energy and resist stresswhy, for example, trees are shaped the way they are. Ecologists make their living by recognizing the interconnectedness of different parts, and different disciplines.

      What we must do now, however, is to unify science and the social sciences and humanities further in the service of preserving the earth. That challenge is stretching ecology in new directions. To sustain the planet, we must be able to protect the goods and services ecosystems provide, and that requires knowing what they mean to us. In large part, that is the domain of economics. Bringing ecology and economics together is not new, and most land-grant universities have strong departments of agricultural and resource economics that deal with the economics of agriculture, fisheries, and forests. However, new dimensions in environmental and ecological economics have been developing rapidly, focusing on questions about the value of whole ecosystems, about the optimal design of nature reserves, and about how to manage public goods. Broadly understood, environmental public goods include the air we breathe and the water we drink, the fish we catch and the lakes and oceans that sustain them, as well as the antibiotics that have contributed so much to the advancement of medical care.

      Ecology views biological systems as wholes, not as independent parts, while seeking to elucidate how the wholes emerge from and affect the parts. Increasingly, such a holistic perspective, rechristened at places like the Santa Fe Institute as "the theory of complex adaptive systems," has informed understanding and improved management of economic and financial systems, social systems, complex materials, and even physiology and medicine. Essentially, that means little more than taking an ecological approach to such systems. (6)
