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.

Scattered throughout the Great Plains are many isolated areas of varying size and ecology, quite distinct from the surrounding grasslands. Such spaces can be uplands like the Black Hills, low hills like the Nebraska Sand Hills, or linear areas such as shallow river valleys and deeply incised canyons. While the notion of “islands” is not a new one among ecologists, its application in Plains archaeology is.

The contributors to this volume seek to illustrate the different ways that the spatial, structural, and temporal nature of islands conditioned the behavior and adaptation of past Plains peoples. This as a first step toward a more detailed analysis of habitat variation and its effects on Plains cultural dynamics and evolution. Although the emphasis is on ecology, several chapters also address social and ideological islands in the form of sacred sites and special hunting grounds.

From a small island in the Baltic Sea to the large tropical islands of Borneo and Madagascar, Messages from Islands is a global tour of these natural, water-bound laboratories. In this career-spanning work, Ilkka Hanski draws upon the many islands on which he performed fieldwork to convey key themes in ecology. By exploring the islands’ biodiversity as an introduction to general issues, Hanski helps us to learn how species and communities interact in fragmented landscapes, how evolution generates biodiversity, and how this biodiversity is maintained over time.

Beginning each chapter on a particular island, Hanski dives into reflections on his own field studies before going on to pursue a variety of ecological questions, including: What is the biodiversity crisis? What are extinction thresholds and extinction debts? What can the biodiversity hypothesis tell us about rapidly increasing allergies, asthma, and other chronic inflammatory disorders? The world’s largest island, Greenland, for instance, is the starting point for a journey into the benefits that humankind acquires from biodiversity, including the staggering biodiversity of microbes in the ecosystems that are closest to us—the ecosystems in our guts, in our respiratory tracts, and under our skin. Conceptually oriented but grounded in an adventurous personal narrative, Messages from Islands is a landmark work that lifts the natural mysteries of islands from the sea, bringing to light the thrilling complexities and connections of ecosystems worldwide.

The desert islands in the Sea of Cortez are little known except to a few intrepid tourists, sailors, and fishermen. Though at first glance these stark islands may appear barren, they are a refuge for an astounding variety of plants and animals. While many of the species are typical of the greater Sonoran Desert region, some are endemic or unique to one or two islands. For example, Isla Santa Catalina is home to the world’s only rattlesnake that has lost its ability to grow a rattle. Other islands host nesting birds, such as Isla Rasa, a tiny, flat flow of basalt lava that attracts nearly half a million elegant and royal terns and Heermann’s gulls each spring.

The Desert Islands of Mexico’s Sea of Cortez is one of the few books devoted to the biogeography of this remarkable part of the world. The book explores the geologic origin of the gulf and its islands, presents some of the basics of island biogeography, details insular life—including residents of the intertidal zone —and provides a brief outlook for preserving this area. More than a simple guidebook, Aitchison’s writing will take both actual and armchair travelers through a gripping tale of natural history.

Like the rest of our fragile planet, the Sea of Cortez and its islands are threatened by humans. Overfishing has eliminated or greatly diminished many fish stocks, and dams on rivers that once flowed into the gulf prevent certain nutrients from reaching the sea. The tenuousness of this area makes the book’s extraordinary photographs and the firsthand descriptions by a well-known teacher, writer, and photographer all the more compelling.

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
