The Biology of Island Floras [Hardcover]

Brings together recent research and novel theories to review studies into the evolution, diversity and conservation of island plants worldwide.Bringing together recent research and novel theories, this book reviews progress in island biogeography, evolution and conservation over a wide spectrum of island floras. It covers recent developments in both theory and methodology, particularly the availability of molecular data, and considers the growing threats to island biota.Bringing together recent research and novel theories, this book reviews progress in island biogeography, evolution and conservation over a wide spectrum of island floras.

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.List of contributors; Preface Juli Caujap?-Castells; 1.
