  • This report is in response to a request from the Exxon Valdez Oil Spill Trustee Council to review the Gulf of Alaska Ecosystem Monitoring and Research Program (GEM). To ensure that the GEM program is based on a science plan that is robust, far-reaching, and scientifically sound, the Trustee Council asked the National Academies to serve as an independent advisor. The Academies appointed a special committee and charged it to review the scope and content of the program as it evolved.

  • The planet is a marvelous place: a place with blue skies, wild storms, deep lakes, and rich and diverse ecosystems. The tides ebb and flow, baby animals are born in the spring, and tropical rain forests harbor an astonishing array of life. The Earth sustains living things and provides humans with the resources to maintain a bountiful way of life: water, soil, and nutrients to grow food, and the mineral and energy resources to build and fuel modern society, among many other things.

  • Why did I decide to write this book? As an undergraduate student I could not make up my mind whether I wanted to be a zoologist or a botanist, so I decided to adopt ecology, in its broadest sense, as my area of interest. This led me to think about interactions among organisms and to try to look at ecosystems from a holistic, rather than from an autecological, point of view. As someone with little formal training in mycology, my interest in fungi started during my doctoral research, especially when attending university-wide lectures by C. T. Ingold,...

  • The idea to apply an assessment of ecosystem health to environmental management emerged in the late 1980s. The parallels with the assessment of human health are very obvious. We go to the doctor to get a diagnosis (to determine what is wrong) and hopefully initiate a cure to bring us back to normal. The doctor will take various measurements and make examinations (pulse, blood pressure, sugar in the urine etc.) before making a diagnosis and suggesting a cure.

  • Soil is a biogeochemically dynamic natural resource that supports all critical components that comprise terrestrial ecosystems. It has been called Earth’s living skin. On its June 11, 2004, cover, Science declared soils to be “the final frontier.” The growing awareness that soil provides a variety of ecosystem services beyond food production has attracted interest in soil from nonsoil scientists.

  • Challenges to sustaining the productivity of oceanic and coastal fisheries have become more critical and complex as these fisheries reach the upper limits to ocean harvests. In addition, it is now clear that we are managing interactive and dynamic food webs rather than sets of independent single-species populations.

  • The last few years have witnessed tremendous changes in the syllabi of environmentally related courses at Advanced Level and in tertiary education. Moreover, there have been major alterations in the way degree and diploma courses are organised in colleges and universities. Syllabus changes reflect the increasing interest in environmental issues, their significance in a political context and their increasing relevance in everyday life.

  • The idea to edit this book started with an e-mail from Suzanne Mekking of Springer Science and Business Media who wanted to make an appointment to talk about current needs for new books in the field of aquatic sciences. During that meeting, she attempted to persuade me into writing a book about my field of research – ecological interactions among coral reefs, mangroves, and seagrass beds by reef fishes. At first, I was not interested due to the large amount of work this would encompass, and my already overloaded work schedule....

  • The late Neogene (the period between − 14 and − 2.4 Ma) is one of the most interesting phases in understand the present conWguration of terrestrial ecosystems. It was during this time that the change took place from the middle Miocene dominant subtropical forests that stretched across southern Europe and western Asia to a more open but still wooded biotope that now prevails in warm–temperate areas. This change in vegetation, which strongly aVected the composition of mammalian faunas, seems to be linked to the rapid spread of grasses around 8–10 Ma ago....

  • This book is about the distribution and abundance of different types of organism, and about the physical, chemical but especially the biological features and interactions that determine these distributions and abundances. Unlike some other sciences, the subject matter of ecology is apparent to everybody: most people have observed and pondered nature, and in this sense most people are ecologists of sorts. But ecology is not an easy science.

  • Forest ecosystems cover large parts of the terrestrial land surface and are major components of the terrestrial carbon (C) cycle. Most important, forest ecosystems accumulate organic compounds with long C residence times in vegetation, detritus and, in particular, the soil by the process of C sequestration. Trees, the major components of forests, absorb large amounts of atmospheric carbon dioxide (CO2) by photosynthesis, and forests return an almost equal amount to the atmosphere by auto- and heterotrophic respiration.

  • This project has its origins in a conference on ecosystem services that Gretchen Daily of the Stanford Biology Department, Geoff Heal of the Columbia Business School, and Peter Raven, Director of the Missouri Botanical Gardens, organized at the Gardens in 1998. Having become intrigued by the concept of ecosystem services, which at the time was still relatively new even within ecological economics, the three of us eagerly attended and immediately noticed that, besides J. B., only one other lawyer was present in the audience of more than a hundred.
