Book Description
As concerns about humankind’s relationship with the environment move inexorably up the agenda, this volume tells the story of the history of the concept of ecology itself and adds much to the historical and philosophical debate over this multifaceted discipline. The text provides readers with an overview of the theoretical, institutional and historical formation of ecological knowledge. The varied local conditions of early ecology are considered in detail, while epistemological problems that lie on the borders of ecology, such as disunity and complexity, are discussed. The book traces the various phases of the history of the concept of ecology itself, from its 19th century origins and antecedents, through the emergence of the environmental movement in the later 20th century, to the future, and how ecology might be located in the environmental science framework of the 21st century. The study of ‘ecological’ phenomena has never been confined solely to the work of researchers who consider themselves ecologists. It is rather a field of knowledge in which a plurality of practices, concepts and theories are developed. Thus, there exist numerous disciplinary subdivisions and research programmes within the field, the boundaries of which remain blurred. As a consequence, the deliberation to adequately identify the ecological field of knowledge, its epistemic and institutional setting, is still going on. This will be of central importance not only in locating ecology in the frame of 21st century environmental sciences but also for a better understanding of how nature and culture are intertwined in debates about pressing problems, such as climate change, the protection of species diversity, or the management of renewable resources.

Book Description
The emergence of landscape ecology during the 1980s represents an impor tant maturation of ecological theory. Once enamored with the conceptual beauty of well-balanced, homogeneous ecosystems, ecologists now assert that much of the essence of ecological systems lies in their lumpiness. Patches with differing properties and behaviors lie strewn across the land scape, products of the complex interactions of climate, disturbance, and biotic processes. It is the collective behavior of this patchwork of eco systems that drives pattern and process of the landscape. is not an end point This realization of the importance of patch dynamics in itself, however. Rather, it is a passage to a new conceptual framework, the internal workings of which remain obscure. The next tier of questions includes: What are the fundamental pieces that compose a landscape? How are these pieces bounded? To what extent do these boundaries influence communication and interaction among patches of the landscape? Will con sideration of the interactions among landscape elements help us to under stand the workings of landscapes? At the core of these questions lies the notion of the ecotone, a term with a lineage that even predates ecosystem. Late in the nineteenth century, F. E. Clements realized that the transition zones between plant communi ties had properties distinct from either of the adjacent communities. Not until the emergence of patch dynamics theory, however, has central signif icance of the ecotone concept become apparent.
