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
A beautifully illustrated guide to the complete mammalian biodiversity of the Philippines’ largest island. Revealing the astounding mammalian diversity found on the largest Philippine island, The Mammals of Luzon Island is a unique book that functions both as a field guide and study of tropical fauna. The book features 120 fully illustrated species profiles and shows how the mammals fit into larger questions related to evolution, ecology, and biogeography. Luzon’s stunning variety of mammals includes giant fruit-eating bats; other bats so small that they can roost inside bamboo stems; giant plant-eating rodents that look like, but are not, squirrels; shrews that weigh less than half an ounce; the rapidly disappearing Philippine warty pig; and the long-tailed macaque, Luzon’s only nonhuman primate. While celebrating Luzon’s remarkably rich mammal fauna, the authors also suggest conservation strategies for the many species that are under threat from a variety of pressures. Based on a century of accumulated data and fifteen years of intensive study, The Mammals of Luzon Island delivers a message that will appeal equally to scientists, conservationists, and ecologically minded travelers.

Book Description
"For many years Alfred Russel Wallace traveled the globe, observing fauna and flora and wondering whether the environment in which they lived affected their development. Island Life, a classic of scientific literature, is the result of those studies. In it, he examines a variety of biospheres to determine whether species are immutable (as was long thought), regardless of changing conditions in their surroundings, or are in fact capable of adapting in order to survive. Island Life is divided into two parts: The Dispersal of Organisms: Its Phenomena, Laws, and Causes and Insular Faunas and Floras. In Part 1, Wallace discusses the distribution across the planet of plants and animals, then examines how changes of climate have affected their dispersal. Part 2 contains case studies of the organisms on islands as varied as the Galapagos, Great Britain, and Madagascar. English naturalist ALFRED RUSSEL WALLACE (18231913) developed a theory of natural selection independent of his contemporary Charles Darwin. His works include Contributions to the Theory of Natural Selection (1870), The Geographical Distribution of Animals (1876), and Darwinism (1889)."

Book Description
Marking the centennial of Alfred Russel Wallace's death, James Costa presents an elegant edition of the "Species Notebook" of 1855-1859, which Wallace kept during his Malay Archipelago expedition. Presented in facsimile with text transcription and annotations, this never-before-published document provides a window into the travels, trials, and genius of the co-discoverer of natural selection. In one section, headed "Note for Organic Law of Change"--a critique of geologist Charles Lyell's anti-evolutionary arguments--Wallace sketches a book he would never write, owing to the unexpected events of 1858. In that year he sent a manuscript announcing his discovery of natural selection to Charles Darwin. Lyell and the botanist Joseph Hooker proposed a joint reading at the Linnean Society of his scientific paper with Darwin's earlier private writings on the subject. Darwin would go on to publish On the Origin of Species in 1859, to much acclaim; pre-empted, Wallace's first book on evolution waited two decades, but by then he had abandoned his original concept. On the Organic Law of Change realizes in spirit Wallace's unfinished project, and asserts his stature as not only a founder of biogeography and the preeminent tropical biologist of his day but as Darwin's equal.
