Hierarchical Perspectives on Marine Complexities

The Gulf of Maine supports a vital fishery for North America and is one of the most intensely studied marine ecosystems in the world. An understanding of its ecology has practical applications to management of other marine systems and fisheries. This book is the first application of Hierarchy Theory to the ecological workings of the Gulf of Maine and of marine ecosystems in general. Hierarchy Theory offers a perspective that simplifies the apparent complications and contradictions of ecosystems, which encompass a number of scales of time (from minutes to decades or longer) and of space (from centimeters to kilometers). Spencer Apollonio explores in detail the idea of natural constraints inherent in hierarchical ecosystems and the impact upon such systems when constraints are reduced or removed. He argues that conventional fisheries management, which practices the removal of these constraints, may be doomed to failure. Apollonio focuses in particular on the "groundfish crisis" in the Gulf, the precipitous decline due to overfishing in populations of cod, haddock, pollock, hakes, and various types of flounders, which have together constituted the mainstay of the Maine fishing industry for centuries. Hierarchical Perspectives on Marine Complexities presents a compelling case for a new approach that holds the promise of resource sustainability in the face of enormously complicated natural and cultural forces.
Complex Ecology
Research papers from the end of twentieth-century have been assembled, alongside expert commentary, for the first collected volume on complexity-based ecology.
Toward a Unified Ecology

The first edition of Toward a Unified Ecology was ahead of its time. For the second edition, the authors present a new synthesis of their core ideas on evaluating communities, organisms, populations, biomes, models, and management. The book now places greater emphasis on post-normal critiques, cognizant of ever-present observer values in the system. The problem it addresses is how to work holistically on complex things that cannot be defined, and this book continues to build an approach to the problem of scaling in ecosystems. Provoked by complexity theory, the authors add a whole new chapter on the central role of narrative in science and how models improve them. The book takes data and modeling seriously, with a sophisticated philosophy of science.
