The Geology and Hydrogeology of Carbonate Islands presents a survey of more than 30 selected islands such as Bermuda, the Bahamas, the Florida Keys, coastal Yucatan, Barbados, the Caymans, Isla de Mona, islands of Polynesia, the Cooks, Guam, Niue, Nauru, Rottnest Island, the Houtman Abrolhos, islands of the Great Barrier Reef and many atolls including Enewetak, Tarawa, Diego Garcia, Mururoa, and the Cocos Islands. The book provides a wealth of observational data and a survey of interpretations on the issues within the intersection of carbonate geology (depositional architecture, diagenetic processes and dolomitization, Cenozoic sea-level history, karstification and blue holes) and island hydrology (distribution of fresh and brackish groundwater, dual-aquifer conceptualizations, modeling of island lenses, water budgets and water resources, effects of climatic variations, island karst, endo-upwelling).

This book is the story of the natural history of Chagos Archipelago, and of the efforts of many to get it recognized as an important and protected wildlife reserve. Exploring its immense natural riches and biodiversity, both on islands and in the marine environment, this book addresses competing claims to its resources, its politics, and the desire of some commercial and political parties to exploit the area. It is about the fight to conserve a wonderland of biodiversity and obtain its protection from exploitation, especially of its reefs and other marine life. This book shows the importance of the Chagos Archipelago and why so much research was done there. Rather than being a typical research book, this work presents research in a narrative form and describes the now substantial Government, UN, and legal interest in the archipelago since the UK was told to ‘decolonise’ it. It is also the story of our planet in miniature: the archipelago encapsulates much of the world’s conservation tribulations in a way we can much more easily understand. This narrative will explore the difficulties faced by the Chagos Archipelago, including displaced people, old and derelict industries (coconut in this case), the military, politics, rich and untouched ecosystems that some want to exploit, ruined habitats on land, climate change, and territorial claims. It will examine how all of these factors have affected the natural history, biodiversity, and conservation of the archipelago. With beautiful photography of the Chagos Archipelago coral reefs and islands, as well as graphs indicating their findings, this book offers professionals, researchers, academics, and students in conservation and biodiversity an insight into one of the world’s most diverse ecosystems. It is also accessible for non‐academic readers with an interest in climate change, biodiversity, and the importance of conservation.

Islands are intrinsic parts of the Indian Ocean Region’s physical geography and human landscape. Historically, many have played substantial roles in the regional cultural and economic networks, as well as in the regional political developments. Today, at least three issues bring these islands back to the forefront of the regional and global affairs, namely geopolitics and strategic matters, environmental conditions and challenges, as well as ocean affairs. However, there has not been yet a lot of research and publications on this phenomenon of islands’ growing significance in the specific context of the Indian Ocean Region. This book provides a rare attempt to cover various issues related to geopolitics, international relations, history, security, anthropology and ocean/environment of Indian Ocean islands and their societies. More specifically, it provides case studies on Sri Lanka (foreign policy), Cocos and Christmas Islands (geo-strategy), Chagos Archipelago (history), Mauritius (‘Indo-Mauritians’), Mauritius and Seychelles (maritime security), European Union and the Indian Ocean Islands (international relations), and Sundarban islands (environment and society). The chapters were originally published in a special issue of the Journal of the Indian Ocean Region.

Canton Atoll has a single passage between the ocean and lagoon and has conspicuous environmental gradients from that passage to the back lagoon. These gradients include the physiography of the lagoon floor, water quality, and the diversity and abundance of corals, fishes, and mollusks. The gradients can apparently be attributed either directly or indirectly to circulation and water motion within the lagoon. Those oceanographic characteristics can, in turn, be attributed to the geological history of the atoll, including some human modification of the pass configuration. In addition to the studies of the atoll lagoon characteristics of the groundwater system are noted. Evidence from isolated standing water bodies on the atoll demonstrates that these features show considerable variability, which may be attributed to a combination of the immediately previous history of these bodies as well as to the physiography of the atoll.

Coral reefs are among Earth's most diverse, productive, and beautiful ecosystems, but until recently, their ecology and the means to manage them have been poorly understood and documented. In response to the inadequate information base for coral reefs, this book reviews the ecological and conservation status of coral reefs of the Western Indian Ocean, bringing together presentations of the region's leading scientists and managers working on coral reefs. Coral Reefs of the Indian Ocean: Their Ecology and Conservation starts with a general overview of the biogeography of the region and a historical account of attempts to conserve this ecosystem. It goes on to describe the state of the reefs in each of the countries with coral reefs, and it concludes with a series of management case studies. The book also summarizes most of the existing ecological information on reefs in this region and efforts at management, making it useful for students, teachers, and investigators interested in tropical or marine ecology, conservation biology and management, and environmental sciences.

This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.
