Providing a broad historical perspective, this book explores the interactions between humans, microorganisms, and plants in a closed habitat, and the life support systems necessary to maintain habitability over long periods of time. Topics include the cultivation of bacteria, microalgae and higher plants; the use of biotechnology to support life outside the Earth's biosphere; methods for recycling air, water and food for human consumption; interactions between humans and other organisms in CMESs; and methods for intensifying the level of photosynthesis. In addition to space the authors investigate problems associated with living conditions in dangerous or difficult environmental areas on Earth such as the Arctic and Antarctica, deserts and mountains.

The book presents a consistent and complete ecosystem theory based on thermodynamic concepts. The first chapters are devoted to an interpretation of the first and second law of thermodynamics in ecosystem context. Then Prigogine's use of far from equilibrium thermodynamic is used on ecosystems to explain their reactions to perturbations. The introduction of the concept exergy makes it possible to give a more profound and comprehensive explanation of the ecosystem's reactions and growth-patterns. A tentative fourth law of thermodynamic is formulated and applied to facilitate these explanations. The trophic chain, the global energy and radiation balance and pattern and the reactions of ecological networks are all explained by the use of exergy. Finally, it is discussed how the presented theory can be applied more widely to explain ecological observations and rules, to assess ecosystem health and to develop ecological models.

"This book is a revised second edition of the first edition. Second ed. includes foreword, introduction, and afterword materials provided by authors. The story itself is that of a two year experiment in the 1990s, the first fully closed system experiment in the world. The authors share the story of "living inside": from their fully self-sufficient diet, daily maintenance of the experiment, and the ways they kept themselves nourished, and entertained for their two years away from the world on the outside. The added edition will also include some highlights, lightly detailing a few of the findings of their experiment"--

Explores the geography, ecology, and antiquity of 'open ecosystems' which include grasslands, savannas, and shrublands.

What do outer space capsules, submarines, and office buildings have in common? Each is conceived as a closed system: a self-sustaining physical environment demarcated from its surroundings by a boundary that does not allow for the transfer of matter or energy. Contemporary discussions about global warming, recycling, and sustainability have emerged as direct conceptual constructs related to the study and analysis of closed systems. From the space program to countercultural architectural groups experimenting with autonomous living, this publication documents a disciplinary transformation and the rise of a new environmental consensus in the form of a synthetic naturalism. It presents an archive of 39 historical living prototypes from 1928 to the present that put forth an unexplored genealogy of closed resource regeneration systems. Prototypes are presented through unique discursive narratives with historical images, and each includes new analysis in the form of a feedback drawing that problematizes the language of environmental representation by illustrating loss, derailment, and the production of new substances and atmospheres.

Ecological Microcosms is a seminal work which reviews the expanding field of enclosed ecosystem research, and relates the results and models of microcosm studies to general concepts in ecology. Microcosms are miniaturized pieces of our biosphere, ranging from streams and lakes to terraria, agroecosystems, and waste systems. The study of these simplified ecosystems is providing provocative insights into ecological principles as well as issues of environmental management and global stability. The authors have used the well-known thermodynamic approach of H.T. Odum and numerous computer simulations. The book also includes an evaluation of alternative mesocosm approaches for the support of humans in space, as well as appendices to aid in the teaching of environmental concepts using student-created microcosms. Ecological Microcosms will be of interest to ecologists, environmental engineers, policy makers and environmental managers, space scientists, and educators. Robert J. Beyers is a Professor of Biology at the University of South Alabama. Howard T. Odum is Graduate Research Professor of Environmental Engineering Sciences at the University of Florida, and was awarded, with Eugene Odum, the 1987 Crafoord Prize in the Biosciences.

Examines how ecosystems can collapse as a result of human activity, and the ecological processes underlying their subsequent recovery.

"May be the best book on ecology ever written." -- Michael Crichton, The New York Times. Radical 1971 argument about the root causes of climate change remains a must-read for environmentalists.

It's a story that has never been told … until now. Imagine being sealed into a closed environment for two years — cut off from the outside world with only seven other people — enduring never-ending hunger, severely low levels of oxygen, and extremely difficult relationships. Crew members struggled to survive in Biosphere 2, where they swore nothing would go in or out — no food or water, not even air — all in the name of science. For the first time, biospherian Jane Poynter — who lived and loved in the Biosphere — is ready to share what really happened in there. She takes readers on a riveting, fast-paced trip through shattered lives, scientific discovery, cults, love, fears of insanity, and inspiring human endurance. The eight biospherians who closed themselves into the Biosphere emerged 730 days later… much wiser, thinner, and having done what many had said was impossible.

This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.
