Loss of biodiversity on tropical and subtropical oceanic islands is one of the most pressing conservation issues. These oceanic islands are well known for their unique fauna and ? ora, which evolved over long periods in isolation from external perturbation. However, the maj- ity of these islands in the Paci? c were eventually settled by Polynesians and then by Europeans; by about 200 years ago, only a few island groups remained untouched. The Bonin Islands are one of these groups. The Bonin Island group is one of the most remote in the world. The islands are located 1,000 km south of Japan off the eastern fringe of Eurasia. They were ? rst discovered by the Japanese in 1670, settled by Westerners from Hawaii in 1830, and ? nally recognized as a Japanese territory in 1862 on condition that previous settlers would be protected and allowed to remain with full rights. Because of this complicated history, the Bonins have two names.

Oceanic islands offer biologists unparalleled opportunities to study evolutionary processes and ecological phenomena. However, human activity threatens to alter or destroy many of these fragile ecosystems, with recent estimates suggesting that nearly half of the world's insular endemics are threatened with extinction. Bringing together researchers from around the world, this book illustrates how modern research methods and new concepts have challenged accepted theories and changed our understanding of island flora. Particular attention is given to the impact of molecular studies and the insights that they provide into topics such as colonisation, radiation, diversification and hybridisation. Examples are drawn from around the world, including the Hawaiian archipelago, Galapagos Islands, Madagascar and the Macronesian region. Conservation issues are also highlighted, with coverage of alien species and the role of ex situ conservation providing valuable information that will aid the formulation of management strategies and genetic rescue programmes.

Oceanic islands represent a set of systems in which biological diversity varies as a consequence of remoteness or size, not environment; they are also generally simpler than continental ecosystems. Islands therefore provide an opportunity to determine the direct effects of biological diversity on ecosystem function. The volume addresses the components of biological diversity on islands and their patterns of variation; the modern threats to the maintenance of biological diversity on islands; the consequences of island biology and its modification by humanity regarding aspects of ecosystem function; the global implications of islands for conservation; and how islands can help one to understand the processes inducing changes throughout the world.

Biological Invasions and Global Insect Decline offers the most updated knowledge on how invasive alien species affect insect diversity worldwide. The book provides ongoing research and the most relevant information, covering the main aspects of the impact of biological invasions as well as future insights on mitigation and consequences. It discusses how the introduction of all kinds of organisms, from bacteria and plants to vertebrates, affect current declines in insect diversity. The latter portion of the book delves into existent and future monitoring and management programs, including citizen science and regenerative ecology as socio-ecological solutions to combat these threats. Written and edited by international experts on invasion ecology and insect conservation, this book explores the role of global change and the introduction of invasive species in altering the structure of habitats and how this induces a global insect decline. This will be a valuable resource for entomologists, invasion biologists and other researchers in biodiversity conservation, as well as practitioners and stakeholders concerned about problematic invasive alien species and insect population decline. Offers a concise vision of one of the main causes of insect extinctions in the Anthropocene Discusses community ecology, insect conservation, species interactions, restoration ecology Led by a team of editors whose expertise includes invasive alien species, invasion ecology, insect species diversity, and species conservation

Insects are the most interesting and diverse group of organisms on earth, many of which are useful as pollinators of crops and wild plants while others are useful as natural enemies keeping pestiferous insects in check. It is important to conserve these insects for our survival and for this the diversity of insect species inhabiting the different ecosystems of our country must be known. The cornerstone to studies of any kind of organismal diversity is their taxonomic identity. Even after over two and half centuries of studies, so little is known of the insect wealth of our country. It has contributions from taxonomists who have been studying Indian insects for long, this book offers up to date information on many important groups of Indian insects seeking to fill the lacuna of a long felt need for a comprehensive work on the taxonomy of Indian insects. Salient features: Provides an up-to-date taxonomy of major insect groups of India Presents identification keys with illustrations of several important groups of Indian insects Gives a new insight into why insects are so abundant Addresses fundamental questions in mechanoreception and cross kingdom interactions using insects as model systems Indian Insects: Diversity and Science is a festschrift to Professor C. A. Viraktamath, an insect taxonomist par excellence. It has been designed to cater to the needs of academicians, researchers and students who wish to identify insects collected from local environments and will be an invaluable aid for those working in the areas of systematics, ecology, behaviour, diversity and the conservation of insects.

This volume contains the papers presented at a conference on "The rehabilitation of severely damaged land and freshwater eco systems in temperate zones", held at Reykjavik, Iceland, from 4th to 11th July, 1976. The meeting was held under the auspices of the Ecosciences Panel of the N.A.T.O. Science Committee, and the organising expenses and greater part of the expenses of the speakers and chairmen were provided by N.A.T.O. The scientific programme was planned by M. W. Holdgate and M. J. Woodman, in consultation with numerous colleagues, and especially with the Administrative Director of the Conference in Iceland, Dr. Sturla Fridriksson. Iceland proved a particularly suitable location for such a Conference. Geologically, it is one of the youngest countries 1n the world, owing its origin to the up-welling of volcanic rock along the spreading zone of the mid-Atlantic ridge within the past 20 million years. Its structure, northern oceanic situation, recent glaciation and continuing volcanic activity make it distinct as a habitat and have given it a flora and fauna of especial interest. It is also a land of great natural beauty with its ice caps, waterfalls, volcanic landforms, geothermal features and dramatic coasts. In addition, its ecosystems have proved except ionally vulnerable to man's impact and it presents the kind of problem with which the Conference was concerned in an acute form.
