Poole Harbour is protected and recognised, nationally and internationally, for its ecological importance. However, it has also been classified as polluted and eutrophic. These twin designations – protected yet polluted – exemplify the condition of many estuaries, making Poole Harbour an ideal subject for elucidating the circumstances behind this apparent paradox. The outcome of a conference entitled ‘Spotlight on Poole Harbour: Environment & Economics’ organised by the Poole Harbour Study Group, this book comprises four main parts. Part I, ‘Background’, provides a broad introduction to the harbour in terms of its pre-historical and historical significance for human communities and gives a conceptual overview of its modern character and uses. Part II, ‘Ecology’, contains chapters ranging from plankton to marine mammals. The subsequent parts focus on industries dependent on the biological and chemical ‘ecological services’ of the estuary: Part III, ‘Fisheries’, covers recreational and commercial fishing and aquaculture, examining economic value and key shellfish species. Part IV, ‘Water Quality’, addresses those industries that require the harbour to remediate various effluents, as well as some of the environmental consequences and noteworthy efforts to reduce such impacts. Part V, ‘Conclusion’, by the editors examines certain general shortcomings of environmental legislation and regulation manifest in the case of Poole Harbour. A central concern throughout is the question of sustainable development in coastal and marine contexts, making this wide-ranging study relevant well beyond the bounds of its primary geographical focus.

Poole Harbour's unique combination of physical characteristics provide for a rich and productive ecological community recognised for its internationally significant bird populations and as a haven for the naturalisation of exotic species. But the Harbour is also exceptional in the extent to which it represents in microcosm the world-wide tensions between environment and development. The contrasts are sometimes startling: the narrow Harbour entrance separates an unspoilt natural environment of considerable importance from an urban landscape where property competes with Manhattan and Hong Kong Island in the world-wide table of real estate values. The Harbour serves as a port, fishing ground, a receiver of effluent and increasingly as a playground for the affluent. It also lies above Europe's largest on-shore oil-field. The Ecology of Poole Harbour brings together for the first time expert contributions in such a way as to provide a picture of the ecology of the Harbour system as a whole. It covers all the major habitats from reed beds and salt marshes to the extensive mudflats and unseen sub-tidal regions, while also examining in some detail a wide range of ecological phenomena and issues. * First expert overview of ecology of Poole Harbour as a whole

Sacred Ecology examines bodies of knowledge held by indigenous and other rural peoples around the world, and asks how we can learn from this knowledge and ways of knowing. Berkes explores the importance of local and indigenous knowledge as a complement to scientific ecology, and its cultural and political significance for indigenous groups themselves. With updates of relevant links for further learning and over 180 new references, the fourth edition gives increased voice to indigenous authors, and reflects the remarkable increase in published local observations of climate change.

Today there is a bewildering diversity of views on ecology and the natural environment. With more than two hundred distinct and valuable perspectives on the natural world—and with scientists, economists, ethicists, activists, philosophers, and others often taking completely different stances on the issues—how can we come to agreement to solve our toughest environmental problems? In response to this pressing need, Integral Ecology unites valuable insights from multiple perspectives into a comprehensive theoretical framework—one that can be put to use right now. The framework is based on Integral Theory, as well as Ken Wilber’s AQAL model, and is the result of over a decade of research exploring the myriad perspectives on ecology available to us today and their respective methodologies. Dozens of real-life applications and examples of this framework currently in use are examined, including three in-depth case studies: work with marine fisheries in Hawai’i, strategies of eco-activists to protect Canada’s Great Bear Rainforest, and a study of community development in El Salvador. In addition, eighteen personal practices of transformation are provided for you to increase your own integral ecological awareness. Integral Ecology provides the most sophisticated application and extension of Integral Theory available today, and as such it serves as a template for any truly integral effort.

Urbanization has reached unprecedented levels in the estuarine and coastal zone, particularly in the Asia Pacific region where mega-cities and mega-harbours are still growing. This book demonstrates the different solutions and pitfalls, successes and failures in a large number of ports and harbours in the Asia Pacific Region, and shows how science can provide ecologically sustainable solutions that apply wherever the growth of mega-harbours occurs.

Trace metals play key roles in life - all are toxic above a threshold bioavailability, yet many are essential to metabolism at lower doses. It is important to appreciate the natural history of an organism in order to understand the interaction between its biology and trace metals. The countryside and indeed the natural history of the British Isles are littered with the effects of metals, mostly via historical mining and subsequent industrial development. This fascinating story encompasses history, economics, geography, geology, chemistry, biochemistry, physiology, ecology, ecotoxicology and above all natural history. Examples abound of interactions between organisms and metals in the terrestrial, freshwater, estuarine, coastal and oceanic environments in and around the British Isles. Many of these interactions have nothing to do with metal pollution. All organisms are affected from bacteria, plants and invertebrates to charismatic species such as seals, dolphins, whales and seabirds. All have a tale to tell.

Hong Kong is strategically located between the temperate Japonic and the great tropical Indo-West-Pacific zoogeographic provinces. Influenced by the currents of the South China Sea and the huge outflow of fresh water from the Pearl River, Hong Kong's marine flora and fauna are extremely diverse. Temperate species may appear, if only briefly, during the cooler winter months. Conversely, air and water temperatures remain high enough for a strong tropical component: Hong Kong is comparatively rich in mangrove stands and reef corals are well developed subtidally. There is a strong north-west to south-east salinity gradient further enhancing diversity. Geologically, the Hong Kong shore is a 'drowned' coastline, deeply incised and with former mountain peaks represented by numerous off-shore islands. This book reviews the factors creating and maintaining Hong Kong's living shore, and describes the wide range of plants and animals found within the intertidal boundaries of the shore. A full range from exposure to shelter is to be found, from communities of the sheer rock faces, beaten by the storm waves of the South China Sea, to the denizens of mudflats in high shelter at the heads of harbours and inlets. For the first time the occupants of these various shores are illustrated and described, both as individual species and as components of a rich mosaic of life. The factors of pollution and development that are destroying the diversity of the rich complex of shores are described.
