Download or read book Darwin s Finches written by David Lack and published by Cambridge University Press. This book was released on 1983-01-28 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: David Lack's classic work on the finches of the Galapagos Islands (Darwin's Finches) was first published in 1947; few books have had such a great impact on evolutionary biology, indeed it is still one of the most succinct and fascinating treatises ever written about the origin of new species. The 1947 version is reproduced with facsimile pages of the original text, tables and line illustrations. The major feature of this reprint is the additional material supplied by Dr Peter Boag and Dr Laurene Ratcliffe who have both completed studies on the Galapagos. The readership will comprise students of evolution and ecology and those interested in the history of evolutionary thought. Amateur ornithologists and tourists visiting the Galapagos Islands will find this account fascinating.

Book excerpt: "The book strikes a balance between classical fundamental information and the recent developments in plant systematics. Special attention has been devoted to the information on botanical nomenclature, identification and phylogeny of angiosperms with numerous relevant examples and detailed explanation of the important nomenclatural problems. An attempt has been made to present a continuity between orthodox and contemporary identification methods by working on a common example. The methods of identification using computers have been further explored to help better online identification. The chapter on cladistic methods has been totally revised, and molecular systematics discussed in considerable detail."--Jacket.

Available in PDF, EPUB and Kindle. Book excerpt: Dictionary of South American Trees provides a single-source reference for botanists, biologists, ecologists, and climatologists on the many native trees in South America. The index lets readers find a tree in four languages, by its common name, or abbreviation, followed by taxonomy that includes common uses for each part of the tree. Using this information, scientists and students can identify and classify plants, their growth structure and environment, the uses of their products, and alternative options with similar characteristics. - Complete coverage of all native South American trees—the only single-source reference for botanists, biologists, ecologists and climatologists working in this diverse and changing region - Includes taxonomy at genera, species, sub-species, and varietal levels, providing information from the most basic level up and allowing readers to identify their subjects using numerous criteria - Indicates Latin, English, French, and Spanish names as well as common names and abbreviations, facilitating accurate and efficient identification - Provides growth information, climatology, ecology and uses for the tree to provide insight into each tree as well as for comparative purposes when seeking similar tree-based resources
