Book Description
This book contains 28 chapters with emphasis on the interactive nature of the relationships between the soil, plant, animal and environmental components of grassland systems, both natural and managed. It analyses the present knowledge and the future trends of research for combining the classical view of grasslands, as a resource for secure feeding of an increasing human population, with the more recent perspective of the contribution of grasslands to the mitigation of environmental impacts and biodiversity erosion as consequences of human society activities. The chapters are organized within five sections dealing with the different functions and the main ecosystem services expected from grasslands: (i) domestic herbivore feeding and animal production; (ii) the regulation of biogeochemical cycles and its consequences for the environment; (iii) dynamics of biodiversity hosted by grasslands; (iv) integration of grasslands within sustainable animal production systems; and (v) interactions of grassland areas with other land use systems at the landscape level.

Book Description
The Ecosystem Concept in Natural Resource Management focuses on the ecosystem concept and its application to natural resource management. It presents examples of research concepts on natural resource phenomena and discusses ecosystem implications for natural resource management. It also covers range, forest, watershed, fisheries, and wildlife resource science and management. Organized into four sections encompassing 10 chapters, this volume begins with an overview of the meaning, origin, and importance of ecosystem concepts before proceeding with a discussion of field research projects that address the ecosystem concept and the ways in which the concept has been or can be useful in both research and management in natural resource sciences. More specifically, it explores major developments in the field of ecology in relation to natural resource management, with examples from forest ecology. It also introduces the reader to procedures for studying grassland ecosystems, the watershed-ecosystem concept and studies of nutrient cycles, ecosystem concepts in forestry, ecosystem models in watershed management, and the implementation of the ecosystem concept in training in the natural resource sciences. This book is a valuable resource for scientists, educators, technicians, and training resource managers, as well as students in resource management courses.

Book Description
Marine Ecological Processes is a modern review and synthesis of marine ecology that provides the reader - particularly the graduate student - with a lucid introduction to the intellectual concepts, approaches, and methods of this evolving discipline. Comprehensive in its coverage, this book focuses on the processes controlling marine ecosystems, communities, and populations and demonstrates how general ecological principles - derived from terrestrial and freshwater systems as well - apply to marine ecosystems. Numerous illustrations, examples, and references clearly impart to the reader the current state of research in this field; its achievements as well as unresolved controversies.

Book Description
One aim of the physical sciences has been to give an exact picture of the material world. One achievement of physics in the twentieth century has been to prove that that aim is unattainable . . . . There is no absolute knowledge. And those who claim it, whether they are scientists or dogmatists, open the door to tragedy. All information is imperfect. We have to treat it with humility. Bronowski (1973) The Ascent of Man It seems particularly appropriate to us to begin this book with Jacob Bronowski's passionate message firmly in mind. Those who set out to construct numerical models, especially ones that are mechanistic and essentially deterministic, must work always with this awareness as a backdrop for their efforts. But this is also true for the most meticulous physiologist or observant naturalist. We are all dealing with simplifications and abstractions, all trying to figure out how nature works. Unfortunately, this common pursuit does not always lead to mutual understanding, and we have become increasingly aware over the past six years that many ecologists feel a certain hostility or at least distrust toward numerical modeling. In a number of cases the reasons for such feelings are personal and very understandable-hard gotten data skimmed off by someone with little appreciation for the difficulties involved in obtaining reliable measurements, grandiose claims of predictability, the tendency for some model builders to treat other scientists as number-getters whose research can be directed in response to the needs of the model, etc.

Book Description
The oceans represent a vast, complex and poorly understood ecosystem. Marine Ecological Processes is a modern review and synthesis of marine ecology that provides the reader with a lucid introduction to the intellectual concepts, approaches, and methods of this evolving discipline. Comprehensive in its coverage, this book focuses on the processes controlling marine ecosystems, communities, and populations and demonstrates how general ecological principles--derived from terrestrial and freshwater systems as well--apply to marine ecosystems. Global warming and increased eutrophication and wetland destruction in recent years has made the study of ecological processes even more important for the preservation of marine environments. This thoroughly updated and expanded edition will provide students of marine ecology, marine biology, and oceanography with numerous illustrations, examples, and references which clearly impart to the reader the current state of research in this field: its achievements as well as unresolved controversies.
