The contents are based upon lectures given at a Seminar organised as the scientific component of the 17th General Meeting of SCOR, held at the Station Biologique de Roscoff, France, on 22-24 October 1984. The original lectures have been substantially extended and revised in order to give a fuller treatment of the subject. The contributions identify important processes influencing (I) Behaviour of chemical species, (II) Nutrient cycling and mechanisms of organic transformations and (III) Uptake of trace elements by living systems. The connection between terrestrial and oceanic systems is a functional one and the consequences of this linkage on the very large variety of coastal systems are profound. It is widely recognized that many of the major processes which influence the biological properties and chemical forms of elements, and their biogeochemical cycles in the ocean occur at the land-sea boundary, especially in estuaries, coastal lagoons, the coastline and the shelf. Over 80% of living systems and their fisheries take place in near shore waters and the consequential production of organic matter produced triggers off the high level of activity. Over the last fifteen years, there has been considerable stimulus to provide framework to evaluate the interactions and effects of human activities. The rich assemblage of tables and figures and of literature citations contained in the chapters provides an excellent basis for in-depth investigations.
Oceanographers, limnologists, aquatic chemists, marine biologists, and environmental specialists will find this book highly valuable reading for advanced research and training purposes.
Using functional ecology as the basis for applying the ecosystem concept in contemporary environmental science and ecology, this second edition of this highly successful volume has been updated to reflect the latest research. It incorporates a strengthened theme in the use of functional ecology in explaining how ecosystems work and how the ecosystem concept may be used in science and applied science, and coverage of the interactions between humans and ecosystems has been substantially bolstered with the addition of chapters on human impacts and large scale impacts on ecosystems, and global environmental change and the consequences for ecosystems.
Presented in a student-friendly format, this book features boxed definitions, examples, case studies, summary points, discussion questions and annotated further reading lists. It provides a concise and accessible synthesis of both ecosystem theory and its applications, and will be a valuable resource for students of environmental studies, ecology and geography.
This book covers major concepts of ecosystem science, biogeochemistry, and energetics. It addresses, contrasts, and compares both terrestrial and aquatic ecosystems. It combines general lessons, concepts, frameworks, and challenges in highly accessible synthesis chapters. It presents firsthand case studies, written by leaders in the field, offering personal insights into how adopting an ecosystem approach led to innovations, new understanding, management changes, and policy solutions.
This book is ideal for advanced undergraduate and graduate students who have had a general biology course, but not further training in ecosystems as well as researchers and professionals in ecology and environmental sciences.Addresses, contrasts, and compares both terrestrial and aquatic ecosystemsCombines general lessons, concepts, frameworks, and challenges in highly accessible synthesis chaptersPresents firsthand case studies, written by leaders in the field, offering personal insights into how adopting an ecosystem approach led to innovations, new understanding, management changes, and policy solutions
Beginning with an overview of how human civilization has altered the face of the Earth, particularly by the destruction of forests, the book details the startling consequences of these actions. Rice provides compelling reasons for government officials, economic leaders, and the public to support efforts to save threatened and endangered plants. Global campaigns to solve environmental problems with plants, such as the development of green roofs and the Green Belt Movement—a women's organization in Kenya that empowers communities worldwide to protect the environment—show readers that efforts to save wild plants can be successful and beneficial to the economic well-being of nations.
Through current scientific evidence, readers see that plants are vital to the ecological health of our planet and understand what can be done to lead to a better—and greener—future
Benefits of plants:Help modulate greenhouse gases Produce almost all oxygen in the air Create cool shade that reduces energy costs Prevent floods, droughts, and soil erosion Produce all of the food in the world Create and preserve soil Create natural habitats Heal the landscape after natural and human disasters
