  • Urban Ecology is the study of ecosystems that include humans living in cities and urbanizing landscapes. It is an emerging, interdisciplinary field that aims to understand how human and ecological processes can coexist in human-dominated systems and help societies with their efforts to become more sustainable. It has deep roots in many disciplines including sociology, geography, urban planning, landscape architecture, engineering, economics, anthropology, climatology, public health, and ecology.

  • Ecology studies interactions among organisms and between organisms and their environment in nature and is also concerned with the effects that organisms have on the inanimate environment. It is concerned with not only what kind of air a species must have but also what effect that species has on the air. This book is not an elementary ecology textbook. A textbook would be longer and more didactic.

  • The 8th International Congress of Ecology was held in Seoul, South Korea in August 2002, and was hosted by the Ecological Society of Korea. The Congress theme was 'Ecological Issues in a Changing World', and this volume includes selected contributions to illustrate some of the important topics which were discussed during the Congress. Problems of scale have exercised the minds of ecologists for many years, and will continue to do so into the future. This volume deals with this subject and with mathematical approaches to improve our understanding of complex ecological systems.

  • The scope of this book is to demonstrate that we do have an ecosystem theory that can be used to describe ecosystem structure and function. It was previously shown in the book, Integration of Ecosystem Theories: A Pattern (3rd edition, 2002), that the various contributions to systems ecology are consistent and together form a pattern of ecological processes. My book with Yuri Svirezhev, Toward a Thermodynamic Theory of Ecosystems (2004), presented the thermodynamics of this pattern in a mathematical language....

  • In this introductory chapter, we indicate the aims and structure of this book. We also indicate some of the ways in which the book is not synoptic in its coverage, but rather offers an interlinked account of some major developments in our understanding of the dynamics of ecological systems, from populations to communities, along with practical applications to important problems.

  • This volume has two first authors because it is a result of very intensive teamwork between the two authors. We have had three brainstorm meetings, each of approximately one week’s duration. There have been numerous pingpong games (questions–answers–new proposals etc.) on the Internet. All the chapters have major contributions from both of us. We hope that the volume therefore demonstrates a synergistic effect, reflecting the positive teamwork that is behind the volume.

  • Microbes produce an extraordinary array of microbial defense systems. These include broad-spectrum classical antibiotics, metabolic byproducts, such as the lactic acids produced by lactobacilli, lytic agents such as lysozymes, numerous types of protein exotoxins, and bacteriocins, which are loosely defined as biologically active protein moieties with a bacteriocidal mode of action.

  • Creating institutions to meet the challenge of sustainability is arguably the most important task confronting society; it is also dauntingly complex. Ecological, economic, and social elements all play a role, but despite ongoing efforts, researchers have yet to succeed in integrating the various disciplines in a way that gives adequate representation to the insights of each.Panarchy, a term devised to describe evolving hierarchical systems with multiple interrelated elements, offers an important new framework for understanding and resolving this dilemma.

  • What is the nature of Nature? Is it harmonious and graceful? Is it divine and providential? Is it cruel and wild? These days, answers to the question 'What is the nature of Nature?' often reverberate with claims of natural unity: every living thing in nature, and this includes humanity, is united. The unity of nature idea appears in many different forms; in the speeches of environmentally conscious politicians, in the academic writings of scientists, in the sermons of theological leaders, and in the slogans of social activists.

  • Through the efforts of a wide array of public and private organizations around the globe, a strong and growing movement is beginning the process of transforming the systems that create the built environment from ones that pay no attention to resources and the environment to a new variety in which these considerations are the pre-eminent criteria for “good” construction. Although dating back only to the early 1990s, there is already ample evidence that the “green building” movement is affecting the design, construction, operation, and disposal of the built environment....

  • From the beginnings of modern science, lakes have fulfilled a focus of attention. Doubtless, this has something to do with the lure that water bodies hold for most of us, as well as for long having been a source of food as well as water. Authors, from Aristotle to Izaak Walton, committed much common knowledge of the freshwater fauna to the formal written record, so it is still a little surprising to realise that the formal study of lakes—limnology (from the Greek word, limnos, a lake)—is scarcely more than a century in age (Forel 1895).
