Organizing Nature explores how the environment is organized in Canada’s resource-dependent economy. The book examines how particular ecosystem components come to be understood as natural resources and how these resources in turn are used to organize life in Canada. In tracing transitions from "ecosystem component" to "resource," this book weaves together the roles that commodification, Indigenous dispossession, and especially a false nature-society binary play in facilitating the conceptual and material construction of resources. Alice Cohen and Andrew Biro present an alternative to this false nature-society binary: one that sees Canadians and their environments in a constant process of making and remaking each other. Through a series of case studies focused on specific resources – fish, forests, carbon, water, land, and life – the book explores six channels through which this remaking occurs: governments, communities, built environments, culture and ideas, economies, and bodies and identities. Ultimately, Organizing Nature encourages readers to think critically about what is at stake when Canadians (re)produce myths about the false separation between Canadian peoples and their environments.
When we hear the word ‘reef’ we most often think of tropical coral reefs and, indeed, those are the most diverse habitats with thousands of different species living on them. But reefs can also be found off the coast of Canada, Brazil and even further north. Off Canada’s coast there are both the Atlantic deep-water coral habitat and the Pacific rocky reef habitat. Reefs is a pictorial celebration of the hugely varied marine life on coral, rock and sand reefs all around the world. From the Great Barrier Reef off Queensland, Australia, to Mabul Island off Borneo, from east African coral reefs stretching from the Red Sea down to Madagascar to the Amazon Reef off Brazil, from the Mesoamerican Reef off Belize to Vancouver Island, the book explores how life on each reef is interdependent. The book also includes examples of how coral bleaching has killed off reefs. Arranged geographically by reef and illustrated with more than 200 colour photographs, each entry is completed with a caption explaining the magnificent natural world on display. From the gender-swapping clownfish to single-cell zooxanthellae, from coral polyps to purple starfish to harlequin shrimp and octopuses, the book is a feast of marine life.
This book presents both state-of-the art knowledge from Recent
coral reefs (1.8 million to a few centuries old) gained since the
eighties, and introduces geologists, oceanographers and
environmentalists to sedimentological and paleoecological studies
of an ecosystem encompassing some of the world's richest
biodiversity. Scleractinian reefs first appeared about 300 million
years ago. Today coral reef systems provide some of the most
sensitive gauges of environmental change, expressing the complex
interplay of chemical, physical, geological and biological factors.
The topics covered will include the evolutionary history of reef
systems and some of the main reef builders since the Cenozoic, the
effects of biological and environmental forces on the zonation of
reef systems and the distribution of reef organisms and on reef
community dynamics through time, changes in the geometry, anatomy
and stratigraphy of reef bodies and systems in relation to changes
in sea level and tectonics, the distribution patterns of
sedimentary (framework or detrital) facies in relation to those of
biological communities, the modes and rates of reef accretion
(progradation, aggradation versus backstepping; coral growth versus
reef growth), the hydrodynamic forces controlling water circulation
through reef structures and their relationship to early diagenetic
processes, the major diagenetic processes affecting reef bodies
through time (replacement and diddolution, dolomitization,
phosphatogenesis), and the record of climate change by both
individual coral colonies and reef systems over the
Quaternary.
There is no question that Africa is endowed with abundant natural resources of different magnitudes. However, more than a decade of high commodity prices and new hydrocarbon discoveries across the continent has led countless international organizations, donor agencies, and non-governmental organizations to devote considerable attention to the potential of natural resource-based development. Natural Resource-Based Development in Africa places a particular emphasis on the actors that help us understand the extent to which resources could be transformed into broader developmental outcomes. Based on a wide variety of primary sources and fieldwork, including in-person interviews and participant observations, this collection contributes to both scholarly and policy discussions around the governance and economic development roles of local entrepreneurs, transnational firms, civil society groups, local communities, and government agencies in Africa's natural resource sectors. Natural Resource-Based Development in Africa explores the impact that these actors have on regional trends such as resource nationalism and local procurement policies as well as grassroots-related issues such as poverty, livelihoods, gender equity, development, and human security.
A beach-goer’s pocket companion for lazy days on the shore, or for the armchair beachcomber recalling the feel of sand between their toes. Noticing and collecting shells is an irresistible and accessible activity for pretty much everyone who goes to the beach, young or old, specialist, or first-timer. Learn more about exploring the seashore and the treasures to be found, from seashells and pebbles to seaweed and sand, and discover the secrets of the tide and conservation, plus how to be a responsible collector and how to record your finds.
Biologists have made significant advances in our understanding of the Earth's shallow subtidal marine ecosystems, but the findings on these disparate regions have never before been documented and gathered in a single volume. Now, in Food Webs and the Dynamics of Marine Reefs, Tim R. McClanahan and George M. Branch fill this lacuna with a comparative and comprehensive collection of nine essays written by experts on specific aquatic regions. Each essay focuses on the food webs of a respective ecosystem and the factors affecting these communities, from the intense and direct pressure of human influence on fisheries to the multi-vector contributors to climate change. The book covers nine shallow water marine ecosystems from selected areas throughout the world: four coral reef systems, three hard bottom systems, and two kelp systems. In summarizing their organization, human influence on them, and recent developments in these ecosystems, the authors contribute to our understanding of their ecological organization and management. Food Webs and the Dynamics of Marine Reefs will be a useful tool for all benthic marine investigators, providing an expert, comparative view of these aquatic regions.
Coral reefs are the most spectacular and diverse ecosystems in the marine environment. Over the last decades, however, dramatic declines of coral reef communities have been observed. Corals are endangered due to natural and anthropogenic detrimental factors, such as global warming and environmental pollution. Based on an international meeting on "Coral Health and Disease" in Eilat, Israel in April 2003, the book starts with case studies of reefs, e.g. the Red Sea, Caribbean, Japan, Indian Ocean and the Great Barrier Reef. The second part on microbial ecology and physiology describes the symbiotic relations of corals and microbes, and the microbial role in nutrition or bleaching resistance of corals. Particular coral diseases such as aspergillosis, white pox, black and white band diseases are treated in the third part. Finally, various hypotheses of the mechanisms of coral bleaching, including a projection of the future of coral reefs, are discussed.
Coral Reefs of the USA provides a complete overview of the present status of knowledge regarding all coral reef areas within the USA and its territories. It is written by the most experienced authorities in their fields and geographic areas. Stretching from the Caribbean to the western Pacific, the coral reefs of the USA span extensive geographic and biotic diversity, occur in a wide variety of geomorphological settings, and provide a representative cross-section of Holocene reef-building. This book will therefore be of broad general interest. For the first time, complete scholarly reviews are given for the geology, geomorphology and the biology of reefs encompassing a vast area stretching from the Mariana Islands in the west, Samoa in the south, Hawaii in the north and the Virgin Islands in the east. This book is not a status report, but will provide up-to-date information about stressors and the biotic responses of the reefs, as well as the geological explanations why these reefs exist in the first place. It will be an invaluable baseline-reference for all those who are engaged in research or management of these coral reefs or to those who simply enjoy being well-informed about one of the most iconic ecosystems of the USA.
This book provides a unique perspective on the destruction - both natural and human-caused - of coral reef ecosystems. Reconstructing the ecological history of coral reefs, the authors evaluate whether recent dramatic changes are novel events or part of a long-term trend or cycle. The text combines principles of geophysics, paleontology, and marine sciences with real-time observation, examining the interacting causes of change: hurricane damage, predators, disease, rising sea-level, nutrient loading, global warming and ocean acidification. Predictions about the future of coral reefs inspire strategies for restoration and management of ecosystems. Useful for students and professionals in ecology and marine biology, including environmental managers.
Canada and the United States share the world's longest international border. For those living in the immediate vicinity of the Canadian side of the border, the events of 9/11 were a turning point in their relationship with their communities, their American neighbours and government officials. Borderline Canadianness offers a unique ethnographic approach to Canadian border life. The accounts of local residents, taken from interviews and press reports in Ontario's Niagara region, demonstrate how borders and everyday nationalism are articulated in complex ways across region, class, race, and gender. Jane Helleiner's examination begins with a focus on the "de-bordering" initiated by NAFTA and concludes with the "re-bordering" as a result of the 9/11 attacks. Her accounts of border life reveals disconnects between elite border projects and the concerns of ordinary citizens as well as differing views on national belonging. Helleiner has produced a work that illuminates the complexities and inequalities of borders and nationalism in a globalized world.
This book explores the ethnobiology of corals by examining the various ways in which humans, past and present, have exploited and taken care of coral and coralline habitats. This book will bring the educated general audience closer to corals by exploring the various circumstances of human-coral coexistence by providing scientifically sound and jargon-free perspectives and experiences from across the globe. Corals are a vital part of the marine environment since they promote and sustain marine and global biodiversity while providing numerous other environmental and cultural services. Countless valuable coral conservation efforts are published in academic and general audience venues on a daily basis. However relevant, few of these reports show a direct, deeper understanding of the intimate relationship between people and corals throughout the world's societies. Ethnobiology of Corals and Coral Reefs establishes an intimate bond between the audience and the wonder of corals and their importance to humankind.
Colonial Geography charts changes in conceptions of the relationship between people and landscapes in mainland Tanzania during the German colonial period. In German minds, colonial development would depend on the relationship between East Africans and the landscape. Colonial Geography argues that the most important element in German imperialism was not its violence but its attempts to apply racial thinking to the mastery and control of space. Utilizing approaches drawn from critical geography, the book argues that the development of a representational space of empire had serious consequences for German colonialism and the population of East Africa. Colonial Geography shows how spatial thinking shaped ideas about race and empire in the period of New Imperialism.
Reef Life is the story of how Callum Roberts, Britain's pre-eminent marine conservation scientist, fell in love with coral reefs and embarked on a thirty-year career. He began as a young university student who had never been abroad, spending a summer helping to map the unknown reefs of Saudi Arabia. And from that moment, when Callum first cleared his mask, he's never looked back, moving on to survey Sharm El Sheikh, and from there diving and researching all over the world, including Australia's imperilled Great Barrier Reef and the more resilient reefs of the Caribbean. His stories are astonishing, lyrical and laced with a wonderful wry humour - and they allow us privileged access to, and understanding of, the science of our oceans and reefs. Reading this book will also commit readers to support Callum's goal to get marine reserve status for ten percent of the world's ocean.
Tropical coral reefs are important ecosystems. They are economically important to coastal communities living in predominantly developing countries, and also provide shoreline protection, catalyse land formation enabling human habitation, act as a carbon sink and are a repository for genetic and species diversity rivalling rainforests. In the face of mounting man-made pressure from pollution, climate change and over-exploitation, these ecosystems increasingly need action to be taken to ensure their conservation and long term sustainable development. International Environmental Law and the Conservation of Coral Reefs breaks new ground by providing the first in-depth account of the ways in which multilateral environmental treaty regimes are seeking to encourage and improve the conservation of tropical coral reef ecosystems. In so doing, the work aims to raise the profile of such activities in order to reinforce their status on the environmental agenda. The book also has wider implications for international environmental law, arguing that sectorial legal action, provided it remains co-ordinated through a global forum that recognises and reflects the inter-connections between all elements of the natural environment, is the most effective way for international law to enhance the conservation of certain habitats. This book will be invaluable to environmental lawyers, legal researchers, marine conservationists and other stakeholders in coral reefs.

What lies beneath the surface of the ocean has mystified humankind for millennia. We have explored more of the surface of the Moon than we have of the deep sea. From vampire squid to giant spider crabs, and from hydrothermal vents to bioluminescence, its watery depths are both fascinating and terrifying. Deep Water explores, through spectacular images and expert text, how this unique habitat came into being, what lives there and why, how it has evolved and what the future will bring for this dark and mysterious environment.
Very Short Introductions: Brilliant, Sharp, Inspiring Coral reefs are among the most beautiful, and most diverse, of ecosystems. Early seafarers were wary of them, naturalists were confused by them, yet many coastal people benefited greatly from these mysterious rocky structures that grew up to the surface of the sea. They have been rich in their supply of food, and they provided a breakwater from storms and high waves to countless coastal communities that developed from their protection. Their scale is enormous and their value high. Found in countless locations around the world, from the Indo-Pacific coral reef province to the Caribbean and Australia, they support both marine and human life. But today coral reefs are in trouble, with many dying or suffering from over-exploitation, pollution, and the warming and acidification of the oceans. Understanding reefs, their conservation and management, is vital, and so is conveying this to authority if we are to preserve these remarkable ecosystems. In this Very Short Introduction Charles Sheppard describes the complex structure and interdependencies of a reef, how reefs have evolved, the diversity of marine life that they support, and their importance to the human population who live beside them. This new edition describes the latest research on the complex symbioses of coral animals with microorganisms. It also highlights the scale of the challenge facing our reefs today, following recent ocean heatwaves - part of wider climate disruption - that killed half the world's reefs, and considers what can be done to preserve these essential and vibrant ecosystems. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
One of the most dire consequences of global climate change for coral reefs is the increased frequency and severity of mass coral bleaching events. This volume provides information on the causes and consequences of coral bleaching for coral reef ecosystems, from the level of individual colonies to ecosystems and at different spatial scales, as well as a detailed analysis of how it can be detected and quantified. Future scenarios based on modelling efforts and the potential mechanisms of acclimatisation and adaptation are reviewed. The much more severe coral bleaching events experienced on Caribbean coral reefs (compared with those of the Indo-Pacific) are discussed, as are the differences in bleaching susceptibility and recovery that have been observed on smaller geographic scales.
Beyond the Megacity connects and reconnects the global debate on the contemporary urban condition to the Latin American tradition of seeing, considering, and theorizing urbanization from the margins. It develops the approach of "peripheral urbanization" as a way to integrate the theoretical agendas belonging to global suburbanisms, neo-Marxist accounts of planetary urbanization, and postcolonial urban studies, and to move urban theory closer to the complexity and diversity of urbanization in the Global South. From an interdisciplinary perspective, Beyond the Megacity investigates the natures, causes, implications, and politics of current urbanization processes in Latin America. The book draws on case studies from various countries across the region, covering theoretical and disciplinary approaches from the fields of geography, anthropology, sociology, urban studies, agrarian studies, and urban and regional planning, and is written by academics, journalists, practitioners, and scholar-activists. Beyond the Megacity unites these unique perspectives by shifting attention to the places, processes, practices, and bodies of knowledge that have often been neglected in the past.
Interrelationships Between Corals and Fisheries is derived from a workshop held by the Gulf of Mexico Fishery Management Council in Tampa, Florida in May 2013, where world authorities came together to discuss the current problems in managing tropical fisheries and offered suggestions for future directions for both researchers and environmental resource managers. This book addresses current and emerging threats as well as challenges and opportunities for managing corals and associated fisheries. It provides an information baseline toward a better understanding of how corals and the consequences of coral condition influence fish populations, especially as they relate to management of those populations. The book contains content from presentations modified as a result of interactions and discussions with colleagues and peer reviews by global experts in corals and fisheries. Many chapters include additional materials not presented in the workshop. There are also papers that were not presented at the workshop but contribute to the central theme of the book. Topics covered include: Global decline in coral reefs and impacts on fishery yields Distribution and diversity in the Gulf of Mexico Implementation of Coral Habitat Areas of Particular Concern (CHAPCs) Deepwater coral/sponge habitats Coral populations on offshore platforms Mangrove connectivity for sustaining coral reef fisheries Restoring deepwater coral ecosystems and fisheries after the Deepwater Horizon oil spill Predictive mapping of coral reef fish Covering a range of subject matter, most of the chapters offer suggestions for future research on the interrelationships between corals and fisheries. In addition, the final chapter presents a summary on these interrelationships and discusses managing them for the future.
For those who depend on the bounty of the sea for their livelihoods, climate change and its consequences (warming water, coral bleaching, rising sea levels) could spell disaster. The region comprising the eastern coastline of Africa and the islands of the western Indian Ocean-home to many of the Earth's most impoverished people-is particularly vulnerable to significant climate impacts. Focusing on coral reef fisheries in these areas, which collectively support millions of people, this book provides a tool box of options for confronting the consequences of climate change through building local-scale adaptive capacity and improving the condition of natural resources. This requires strengthening a society's flexibility, assets, learning, and social organizations, as well as restricting or limiting its resource use. These two broad concepts-building social capacity and limiting certain types of resource use-interact in complicated ways, requiring coordinated actions. The authors argue that adaptation solutions are context dependent, determined in part by local resource conditions, human adaptive capacity, and exposure to climate change impacts, but also by a people's history, culture, and aspirations. Providing an up-to-date and original synthesis of environmental stress, natural resources, and the socioeconomics of climate change, Adapting to a Changing Environment develops a framework to provide governments, scientists, managers, and donors with critical information about local context, encouraging the implementation of nuanced actions that reflect local conditions.
Coral reefs are an important tourism resource for many coastal and island destinations and generate a range of benefits to their local communities, including as a food source, income from tourism, employment and recreational opportunities. However, coral reefs are under increasing threat from climate change and related impacts such as coral bleaching and ocean acidification. Other anthropogenic stresses include over-fishing, anchor damage, coastal development, agricultural run-off, sedimentation and coral mining. This book adopts a multidisciplinary approach to review these issues as they relate to the sustainable management of coral reef tourism destinations. It incorporates coral reef science, management, conservation and tourism perspectives and takes a global perspective of coral reef tourism issues covering many of the world's most significant coral reef destinations. These include the Great Barrier Reef and Ningaloo Reef in Australia, the Red Sea, Pacific Islands, South East Asia, the Maldives, the Caribbean islands, Florida Keys and Brazil. Specific issues addressed include climate change, pollution threats, fishing, island tourism, scuba diving, marine wildlife, governance, sustainability, conservation and community resilience. The book also issues a call for more thoughtful development of coral reef experiences where the ecological needs of coral reefs are placed ahead of the economic desires of the tourism industry.
This book provides a rich and illuminating account of the peripheries of urban, regional, and transnational development in South Korea. Engaging with the ideas of "core location," a term coined by Baik Young-seo, and "Asia as method," a concept with a century-old intellectual lineage in East Asia, each chapter in the volume discusses the ways in which a place can be studied in an increasingly globalized world. Examining cases set in the Jeju English Education City, anti-poverty and community activist sites, rural areas home to large numbers of migrant women, and Korea's Chinatowns, greenbelts, and textile factories, the collection develops a relational understanding of a place as a constellation of local and global forces and processes that interact and contradict in particular ways. Each chapter also explores multiple modes of urban marginality and discusses how understanding them shapes the methods of academic praxis for social justice causes and decolonialized scholarship. This book is the outcome of several years of interdisciplinary collaborations and dialogues among scholars based in geography, architecture, anthropology, and urban politics. |
