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.

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.

The recent discovery of diverse fossil flowers and floral organs in Cretaceous strata has revealed astonishing details about the structural and systematic diversity of early angiosperms. Exploring the rich fossil record that has accumulated over the last three decades, this is a unique study of the evolutionary history of flowering plants from their earliest phases in obscurity to their dominance in modern vegetation. The discussion provides comprehensive biological and geological background information, before moving on to summarise the fossil record in detail. Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of the pattern of angiosperm evolution through time. Synthesising palaeobotanical data with information from living plants, this unique book explores the latest research in the field, highlighting connections with phylogenetic systematics, structure and the biology of extant angiosperms.

The desert islands of the Gulf of California are among the world's best-preserved archipelagos. The diverse and unique flora, from the cardón forests of Cholludo to the agave-dominated slopes of San Esteban remain much as they were centuries ago, when the Comcaac (Seri people) were the only human presence in the region. Almost 400 plant species exist here, with each island manifesting a unique composition of vegetation and flora. For thousands of years, climatic and biological forces have sculpted a set of unparalleled desert worlds. Plant Life of a Desert Archipelago is the first in-depth coverage of the plants on islands in the Gulf of California found in between the coasts of Baja California and Sonora. The work is the culmination of decades of study by botanist Richard Felger and recent investigations by Benjamin Wilder, in collaboration with Sr. Humberto Romero-Morales, one of the most knowledgeable Seris concerning the region's flora. Their collective effort weaves together careful and accurate botanical science with the rich cultural and stunning physical setting of this island realm. The researchers surveyed, collected, and studied thousands of plants—seen here in meticulous illustrations and stunning color photographs—providing the most precise species accounts of the islands ever made. To access remote parts of the islands the authors worked directly with the Comcaac, an indigenous community who have lived off marine and terrestrial life in this coastal desert region for centuries. Invaluable information regarding indigenous names and distributions are an intrinsic part of this work. The flora descriptions are extraordinarily detailed and painstakingly crafted for field biologists. Conservationists, students, and others who are interested in learning about the natural wealth of the Gulf of California, desert regions, or islands in general are sure to be captivated by this rich and fascinating volume.

The three islands comprising the Cayman Islands support 415 native taxa in a land area over 100 square miles, 29 of which are uniquely Caymanian. This field guide satisfies the needs of the professional botanist, while providing the non-expert and eco-tourist with an introduction to the unique endemic flora of the Cayman Islands.
