Book Description
Wallace's Island Life is one of the foundation works of zoogeography. It focused on the detailed problems of animal dispersal and speciation. Like Darwin, Wallace classified islands as either oceanic (no previous connection to a land mass) or continental (previously connected to a land mass). He considered the means by which each class of island might become colonized, the types of animals most likely to perform the necessary migrations, and the conditions-such as major climactic or geologic change-under which the migrations might have been made. Wallace was the first to use the new knowledge of Pleistocene ice ages to explain certain phenomena of animal distribution, and in Island Life he speculated about the possible causes of glaciation. He was one of the few 19th-century scientists to realize that astronomical causes alone would not suffice, but had to be combined with a corresponding elevation in the northern land mass -- Abe books website.

Book Description
Climate change has shaped life in the past and will continue to do so in the future. Understanding the interactions between climate and biodiversity is a complex challenge to science. With contributions from 60 key researchers, this book examines the ongoing impact of climate change on the ecology and diversity of life on earth. It discusses the latest research within the fields of ecology and systematics, highlighting the increasing integration of their approaches and methods. Topics covered include the influence of climate change on evolutionary and ecological processes such as adaptation, migration, speciation and extinction, and the role of these processes in determining the diversity and biogeographic distribution of species and their populations. This book ultimately illustrates the necessity for global conservation actions to mitigate the effects of climate change in a world that is already undergoing a biodiversity crisis of unprecedented scale.

Book Description
Originally published in 1974, Arctic and Alpine Environments examines, the relatively simple ecosystems of arctic and alpine lands that still occupy extensive areas little disturbed by modern technology. The book argues that there is a necessity for carefully controlled development of the resources of these regions and suggests that there is a risk of irreversible disturbance without full understanding of these regions. This book provides a detailed documentation of cold-stressed arctic and alpine terrestrial environments and systematically deals with the present and past physical environment – climate, hydrology and glaciology; biota – treeline, vegetation, vertebrate zoology, and historical biogeography; abiotic processes – geomorphological and pedological and the role of man – bioclimatology, archaeology and technological impact, including radioecology. The book will appeal to academics and students of environmental and biological science, as well as providing a significant source for conservationists’, government agencies and industrial organizations.

Book Description
Cryptic species are organisms which look identical, but which represent distinct evolutionary lineages. They are an emerging trend in organismal biology across all groups, from flatworms, insects, amphibians, primates, to vascular plants. This book critically evaluates the phenomenon of cryptic species and demonstrates how they can play a valuable role in improving our understanding of evolution, in particular of morphological stasis. It also explores how the recognition of cryptic species is intrinsically linked to the so-called 'species problem', the lack of a unifying species concept in biology, and suggests alternative approaches. Bringing together a range of perspectives from practicing taxonomists, the book presents case studies of cryptic species across a range of animal and plant groups. It will be an invaluable text for all biologists interested in species and their delimitation, definition, and purpose, including undergraduate and graduate students and researchers.

Book Description
Alfred Russel Wallace is best known as the codiscoverer, with Charles Darwin, of natural selection, but he was also history’s foremost tropical naturalist and the father of biogeography, the modern study of the geographical basis of biological diversity. Island Life has long been considered one of his most important works. In it he extends studies on the influence of the glacial epochs on organismal distribution patterns and the characteristics of island biogeography, a topic as vibrant and actively studied today as it was in 1880. The book includes history’s first theory of continental glaciation based on a combination of geographical and astronomical causes, a discussion of island classification, and a survey of worldwide island faunas and floras. The year 2013 will mark the centennial of Wallace’s death and will see a host of symposia and reflections on Wallace’s contributions to evolution and natural history. This reissue of the first edition of Island Life, with a foreword by David Quammen and an extensive commentary by Lawrence R. Heaney, who has spent over three decades studying island biogeography in Southeast Asia, makes this essential and foundational reference available and accessible once again.

Book Description
Many islands currently rely on heavy fuel oil as their primary energy source. As the issue of pollution and climate change became a reality, many countries, including island nations, began looking to reduce their carbon emissions by launching programs and policies designed to ease their transition from oil to alternative energy technologies that are more environmentally friendly. Transitioning Island Nations Into Sustainable Energy Hubs: Emerging Research and Opportunities provides the latest research exploring the theoretical and practical aspects of establishing renewable energy source systems on islands. Featuring coverage on a broad range of topics such as the vision of future energy networks and its role in creating the idea of energy hubs, this book is ideally designed for academicians, environmental professionals, researchers, policy makers, environmental engineers, and individuals seeking current research on renewable energy development.
