Discussions on historical and philosophical issues in ecology have been rather limited. This volume presents an enriched and comprehensive review on ecological issues. The topics covered in this e-book include the emergence of the field of life-history strategies in population ecology, the model building tradition in community ecology, the holism/reductionism debate, the ecosystemic and systemic approach as well as a discussion of the emergence, development and dominance of the biodiversity concept. By bringing together diverse ideas, points of view and theoretical traditions, often treated separately, the book allows the development of ecology as a whole discipline to emerge. This introductory book is intended to stimulate discussion among both beginners and professionals in the field of history and/or philosophy of science, as well as ecologists. The topics covered are also central to the concerns of scholars engaged in environmental studies, environmental ethics and policy-making.
