  • 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 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....

  • 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.

  • As rates of deforestation and land degradation, and losses of biodiversity and ecosystem services, continue to rise globally, the international community is faced with the challenge of finding land use interventions that can mitigate or reduce the impact of these environmental issues. Agroforestry, the integration of trees in farming systems, has the potential for providing rural livelihoods and habitats for species outside formally protected lands, connecting nature reserves, and alleviating resourceuse pressure on conservation areas.

  • 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, given at the University of London.

  • More than ten years ago, two of us (AGH and DGR) were lucky enough to edit a previous symposium of the British Ecological Society (BES) – Aquatic Ecology: Scale, Pattern and Process (Giller, Hildrew & Raffaelli, 1994). In the Introduction to that volume, we pointed out that the BES had not devoted a single previous symposium to aquatic ecosystems.

  • Human activities are affecting the global environment in myriad ways, with numerous direct and indirect effects on ecosystems. The climate and atmospheric composition of Earth are changing rapidly. Humans have directly modified half of the ice-free terrestrial surface and use 40% of terrestrial production. Our actions are causing the sixth major extinction event in the history of life on Earth and are radically modifying the interactions among forests, fields, streams, and oceans.

  • This book addresses the significant environmental changes experienced by high latitude and high altitude ecosystems at the beginning of the 21st century. Increased temperatures and precipitation, reduction in sea ice and glacier ice, the increased levels of UV-radiation and the long-range transported contaminants in arctic and alpine regions are stress factors that challenge terrestrial and aquatic ecosystems.

  • This ancient Native American proverb and what it implies resonates today as it has become increasingly obvious that people’s actions and interactions with the environment affect not only living conditions now, but also those of many generations to follow. Humans must address the effect they have on the Earth’s climate and how their choices today will have an impact on future generations.

  • 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....

  • 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.

  • The Current State and Trends assessment presents the findings of the Condition and Trends Working Group of the Millennium Ecosystem Assessment. This volume documents the current condition and recent trends of the world’s ecosystems, the services they provide, and associated human well-being around the year 2000. Its primary goal is to provide decision-makers, ecosystem managers, and other potential users with objective information and analyses of historical trends and dynamics of the interaction between ecosystem change and human well-being.

  • Large herbivores are, and have for a long time been, among the major drivers for forming the shape and function of terrestrial ecosystems. These animals may modify primary production, nutrient cycles, soil properties, fire regimes as well as other biota. Some large herbivore species/populations are at the edge of extinction and great effort is being made to save them. Other species/populations are under discussion for reintroduction. Still other species occur in dense populations and cause conflicts with other land use interests.

  • From the early explorers onwards, visitors to the Arctic and to Antarctica have commented with great interest on the presence of lakes, wetlands, and fl owing waters. These environments encompass a spectacular range of conditions for aquatic life, from dilute surface melt ponds, to deep, highly stratifi ed, hypersaline lakes.

  • This book began its evolution in 1999 when the British Antarctic Survey, where I worked at the time, began a new research programme on the management of marine ecosystems. This programme concentrated upon the krill-based ecosystem at SouthGeorgia which has been the subject of almost continuous study since the Discovery Expeditions in the 1920s. Latterly, international efforts to understand the dynamics of this ecosystem and the wider Southern Ocean have been coordinated by the Commission for the Conservation of AntarcticMarine Living Resources (CCAMLR)....

  • Drawing on the collective expertise of world authorities, Ecological Basis of Agroforestry employs extensive use of tables and figures to demonstrate how ecologically sustainable agroecosystems can meet the challenges of enhancing crop productivity, soil fertility, and environmental sustainability. Divided into four sections, this comprehensive volume begins with a study of tree-crop interaction in tropical and temperate climates.

  • The success of the first volume of The Biology of Sea Turtles revealed a need for broad but comprehensive reviews of recent major advances in sea turtle biology. At that time, book size constraints as well as the fast-paced changes in some fields dictated that this need could be only partially addressed in a single volume. Many important topics were not covered and were left for future volumes. Volume II emphasizes practical aspects of biology that relate to sea turtle management and changes in marine and coastal ecosystems....

  • An Ecosystem Approach provides a modern perspective of insect ecology that integrates two approaches traditionally used to study insect ecology: evolutionary and ecosystem. This integration substantially broadens the scope of insect ecology and contributes to prediction and resolution of the effects of current environmental changes, as these affect and are affected by insects. The third edition includes an updated and expanded synthesis of feedback and interactions between insects and their environment.
