Book Description
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.

Book Description
In this poineering application of island biogeography theory, Harris presents an alternative to current practices of timber harvesting. "Harris pulls together many threads of biological thinking about islands and their effect on plant and animal survival and evolution. He weaves these threads into a model for managing forest lands in a manner that might serve both our short-term economic and social needs as well as what some people feel is our ancient charge to be steward of all parts of creation."—American Forests Winner of the 1986 Wildlife Society Publication Award

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
The recent progress in analytical methods, aided by bringing in a wide range of other disciplines, opens up the study to a broader field, which means that biogeography now goes far beyond a simple description of the distribution of living species on Earth. Originating with Alexander von Humboldt, biogeography is a discipline in which ecologists and evolutionists aim to understand the way that living species are organized in connection with their environments. Today, as we face major challenges such as global warming, massive species extinction and devastating pandemics, biogeography offers hypotheses and explanations that may help to provide solutions. This book presents as wide an overview as possible of the different fields that biogeography interacts with. Sixteen authors from all over the world offer different approaches based on their specific areas of knowledge and experience; thus, we intend to illustrate the vast number of diverse aspects covered by biogeography.

Book Description
Robert H. MacArthur and Edward O. Wilson's The Theory of Island Biogeography, first published by Princeton in 1967, is one of the most influential books on ecology and evolution to appear in the past half century. By developing a general mathematical theory to explain a crucial ecological problem--the regulation of species diversity in island populations--the book transformed the science of biogeography and ecology as a whole. In The Theory of Island Biogeography Revisited, some of today's most prominent biologists assess the continuing impact of MacArthur and Wilson's book four decades after its publication. Following an opening chapter in which Wilson reflects on island biogeography in the 1960s, fifteen chapters evaluate and demonstrate how the field has extended and confirmed--as well as challenged and modified--MacArthur and Wilson's original ideas. Providing a broad picture of the fundamental ways in which the science of island biogeography has been shaped by MacArthur and Wilson's landmark work, The Theory of Island Biogeography Revisited also points the way toward exciting future research.

Book Description
This thorough and meticulous study, the result of nearly a quarter-century of research, examines the island biogeography of plants on continental islands in Barkley Sound, British Columbia. Invaluable both because of its geographical setting and because of the duration of the study, Plants on Islands summarizes the diversity, dynamics, and distribution of the approximately three hundred species of plants on more than two hundred islands. Martin Cody uses his extensive data set to test various aspects of island biogeographic theory. His thoughtful analysis, constrained by taxon and region, elucidates and enhances the understanding of the biogeographic patterns and dynamics. He provides an overview of the basic theory, concepts, and analytical tools of island biogeography. Also discussed are island relaxation to lower equilibrium species numbers post-isolation, plant distributions variously limited by island area, isolation and climatic differences, adaptation to local abiotic and biotic environments within islands, and the evolution of different island phenotypes. The book concludes with a valuable consideration of equilibrium concepts and of the interplay of coexistence and competition. Certain to challenge, Plants on Islands is among the first books to critically analyze the central tenets of the theory of island biogeography.
