Book Description
In most accounts of geographical phenomena, islands in the middle of the oceans are marginalised and implicitly viewed as of little imortance. This is a convenient rather than a rational view and one which is comprehensively disposed of in this book which examines the great diversity of island environments worldwide and the controls on their development.

Book Description
Bringing together results from over 30 years of research on the Juan Fernández Archipelago off the coast of Chile, this book offers comprehensive coverage of the plants of these special islands. Despite its remote setting in the southeastern Pacific Ocean, the Juan Fernández Archipelago is in many ways an ideal place to ask and attempt to answer basic questions regarding the evolution of vascular plants in an oceanic island environment. By building upon a firm taxonomic base for the flora, a new level of understanding regarding evolution, biogeography, and conservation of the plants is presented. This book is an extensive investigation of the origin and evolution of the flora of an oceanic archipelago, and it serves as a valuable resource for researchers and scholars of island biology as well as for conservation biologists worldwide.

Book Description
The Juan Fernández Archipelago is located in the Pacific Ocean west of Chile at 33° S latitude. Robinson Crusoe Island is 667 km from the continent and approximately four million years old; Alejandro Selkirk Island is an additional 181 km west and only one million years old. The natural impacts of subsidence and erosion have shaped the landscapes of these islands, resulting in progressive changes to their subtropical vegetation. The older island has undergone more substantial changes, due to both natural causes and human impacts. After the discovery of Robinson Crusoe Island in 1574, people began cutting down forests for lumber to construct boats and homes, for firewood, and to make room for pastures. Domesticated plants and animals were introduced, some of which have since become feral or invasive, causing damage to the local vegetation. The wealth of historical records on these activities provides a detailed chronicle of how human beings use their environment for survival in a new ecosystem. This book offers an excellent case study on the impacts that people can have on the resources of an oceanic island.

Book Description
Consuming Ocean Island tells the story of the land and people of Banaba, a small Pacific island, which, from 1900 to 1980, was heavily mined for phosphate, an essential ingredient in fertilizer. As mining stripped away the island's surface, the land was rendered uninhabitable, and the indigenous Banabans were relocated to Rabi Island in Fiji. Katerina Martina Teaiwa tells the story of this human and ecological calamity by weaving together memories, records, and images from displaced islanders, colonial administrators, and employees of the mining company. Her compelling narrative reminds us of what is at stake whenever the interests of industrial agriculture and indigenous minorities come into conflict. The Banaban experience offers insight into the plight of other island peoples facing forced migration as a result of human impact on the environment.

Book Description
This open access book presents a comprehensive synthesis of the biodiversity of the oceanic islands of the Gulf of Guinea, a biodiversity hotspot off the west coast of Central Africa. Written by experts, the book compiles data from a plethora of sources – archives, museums, bibliography, official reports and previously unpublished data – to provide readers with the most updated information about the biological richness of these islands and the conservation issues they face. The Gulf of Guinea Oceanic Islands (Príncipe, São Tomé and Annobón and surrounding islets) present extraordinary levels of endemism across different animal, fungi and plant groups. This very high endemism likely results from the long geological history of the islands and their proximity to the diversity-rich continent. Many researchers, students and conservationists from across the globe are interested in documenting biodiversity on the islands, understanding the evolutionary origins of this diversity, and mitigating the impacts of global change on this unique archipelago. This book aims to be a primer for a broad audience seeking baseline biodiversity information and to serve as a roadmap for future research efforts aiming to fill knowledge gaps in understanding and conserving the unparalleled biodiversity of the Gulf of Guinea islands.

Book Description
Ocean island volcanoes constitute some of the most prominent and rapidly-formed features on Earth, and yet they cannot be explained by conventional plate tectonics. Although typically associated with intraplate settings (hotspots), these volcanoes also occur in different geodynamic settings (near mid-ocean ridges). The nature of ocean island magmatism is still the subject of intense debate within the geological community. Traditionally it has been linked to the presence of mantle plumes at depth (e.g. Hawaii), although the interaction with plate tectonics is also recognized to play a significant role (e.g. Azores, Galápagos). Magma compositions may range from basaltic to more differentiated, which consequently is accompanied by striking changes in the eruption style from effusive-dominated to highly explosive volcanism. Understanding how these magmas evolve and how volcanic processes act at ocean island volcanoes are key issues of modern volcanology. Moreover, the growth of ocean island volcanoes from their rise on the seafloor as seamounts, to island emergence and subsequent formation of shield volcanoes (and in some cases large caldera volcanoes) is governed by multiple interrelated changes. It is well known that competing processes model ocean island volcanoes during alternating and/or coeval periods of construction and destruction. The geological evolution of these volcanoes results from the balance among volcanism, intrusions, tectonics, subsidence/uplift, mass wasting, sedimentation, and subaerial and wave erosion. A better knowledge of the interplay between these processes is crucial to obtain a more comprehensive understanding of the evolution of such volcanoes, and to the eventual formulation of a unified model for ocean island evolution. Ocean islands are especially vulnerable to volcanic eruptions and other geological hazards on account of their typical small size, rough topography and isolation, which make risk management and evacuation difficult. Volcanic eruptions, in particular, may have a significant impact on local populations, infrastructures, economy and even on the global climate. It is therefore fundamental to monitor these volcanoes with complementary geophysical, geodetic and geochemical techniques in order to forecast future eruptions and their impacts. However, the assessment of volcanic hazards on ocean islands is challenging due to the large variety of phenomena involved (e.g. lava flows, tephra fallout, pyroclastic density currents, lahars, gas emissions). Different approaches are used to assess volcanic hazards, either based on empirical methods or sophisticated numerical models, focusing on a single phenomenon or the combination of different hazards. This Frontiers Research Topic aims to promote discussion within the scientific community, representing an important step forward in our knowledge of ocean island volcanoes in order to serve as a reference for future research.

Book Description
This major new field guide covers Madagascar and the Indian Ocean islands, including the Seychelles, Coromos and Mascarenes (Mauritius, Réunion and Rodrigues). The Malagasy region contains one of the most extraordinary concentrations of biodiversity in the world. Its recognition as a zoogeographic region in its own right has recently been confirmed and, all taxa combined, the region was found to hold the second most distinct assemblage of vertebrates in the world after the Australian region, despite being the smallest of them all. This Helm Field Guide covers the whole of the Malagasy region, which comprises the unique island of Madagascar and the various islands and archipelagos of the Indian Ocean including the Seychelles, Comoros and Mascarenes (Mauritius, Réunion and Rodrigues). Every resident and migrant species is covered in full detail with a colour distibution map for each. Vagrants are also treated in detail, but without maps. All species are illustrated on a beautiful series of 124 colour plates, with artwork from John Gale and Brian Small. Conveniently, the plates have been arranged so that all the key species of the various archipelagos are placed together in sections. This is a major work of reference on the birds of the region and will remain the standard text for many years to come.
