Island Life, Or, The Phenomena and Causes of Insular Faunas and Floras


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.

Island Life


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

Excerpt from Island Life: Or, the Phenomena and Causes of Insular Faunas and Floras: Including a Revision and Attempted Solution of the Problem of Geological Climates This edition has been carefully revised throughout, and owing to the great increase to our knowledge Of the Natural History of some of the islands during the last twelve years considerable additions or alterations have been required. The more important of these changes are the following: Chapter VII. The account of the migrations of animals and plants during and since the Glacial Epoch, has been modified to accord with newer information. Chapters VIII and IX. The discussion of the causes of Glacial Epochs and Mild Arctic Climates has been some what modified in view of the late Dr. Croll's remarks, and the argument rendered clearer. Chapter XIII. Several additions to the Fauna of the Galapagos have been noted. Chapter XV. Considerable additions have been made to this chapter embodying the recent discoveries of birds and insects new to the Sandwich Islands, while a much fuller account has been given of its highly peculiar and very interesting flora. Chapter XVI. Important additions and corrections have been made in the lists Of peculiar British animals and plants embodying the most recent information.
