Download or read book Species Concepts and Phylogenetic Theory written by Quentin D. Wheeler and published by Columbia University Press. This book was released on 2000-06-22 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: No question in theoretical biology has been more perennially controversial or perplexing than "What is a species?" Recent advances in phylogenetic theory have called into question traditional views of species and spawned many concepts that are currently competing for general acceptance. Once the subject of esoteric intellectual exercises, the "species problem" has emerged as a critically important aspect of global environmental concerns. Completion of an inventory of biodiversity, success in conservation, predictive knowledge about life on earth, management of material resources, formulation of scientifically credible public policy and law, and more depend upon our adoption of the "right" species concept. Quentin D. Wheeler and Rudolf Meier present a debate among top systematic biology theorists to consider the strengths and weaknesses of five competing concepts. Debaters include (1) Ernst Mayr (Biological Species Concept), (2) Rudolf Meier and Rainer Willmann (Hennigian species concept), (3) Brent Mishler and Edward Theriot (one version of the Phylogenetic Species Concept), (4) Quentin Wheeler and Norman Platnick (a competing version of the Phylogenetic Species Concept), and (5) E. O. Wiley and Richard Mayden (the Evolutionary Species Concept). Each author or pair of authors contributes three essays to the debate: first, a position paper with an opening argument for their respective concept of species; second, a counterpoint view of the weakness of competing concepts; and, finally, a rebuttal of the attacks made by other authors. This unique and lively debate format makes the comparative advantages and disadvantages of competing species concepts clear and accessible in a single book for the first time, bringing to light numerous controversies in phylogenetic theory, taxonomy, and philosophy of science that are important to a wide audience. Species Concepts and Phylogenetic Theory will meet a need among scientists, conservationists, policy-makers, and students of biology for an explicit, critical evaluation of a large and complex literature on species. An important reference for professionals, the book will prove especially useful in classrooms and discussion groups where students may find a concise, lucid entrée to one of the most complex questions facing science and society.

Download or read book The Mexican Transition Zone written by Juan J. Morrone and published by Springer Nature. This book was released on 2020-07-02 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an evolutionary biogeographic analysis of the Mexican Transition Zone, which is situated in the overlap of the Nearctic and Neotropical regions. It includes a comprehensive review of previous track, cladistic and molecular biogeographic analyses and is illustrated with full color maps and vegetation photographs of the respective areas covered. Given its scope, the book will be of interest to students and researchers whose work involves systematic and biogeographic analyses of plant and animal taxa of the Mexican Transition Zone or other transition zones of the world, and to ecologists working in biodiversity conservation, who will be able to appreciate the evolutionary relevance of the Mexican Transition Zone for establishing conservation areas..

Download or read book The Future of Phylogenetic Systematics written by David Williams and published by Cambridge University Press. This book was released on 2016-07-21 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: Willi Hennig (1913–76), founder of phylogenetic systematics, revolutionised our understanding of the relationships among species and their natural classification. An expert on Diptera and fossil insects, Hennig's ideas were applicable to all organisms. He wrote about the science of taxonomy or systematics, refining and promoting discussion of the precise meaning of the term 'relationship', the nature of systematic evidence, and how those matters impinge on a precise understanding of monophyly, paraphyly, and polyphyly. Hennig's contributions are relevant today and are a platform for the future. This book focuses on the intellectual aspects of Hennig's work and gives dimension to the future of the subject in relation to Hennig's foundational contributions to the field of phylogenetic systematics. Suitable for graduate students and academic researchers, this book will also appeal to philosophers and historians interested in the legacy of Willi Hennig.
Download or read book Riceland Spiders of South and Southeast Asia written by A. T. Barrion and published by Int. Rice Res. Inst.. This book was released on 1995 with total page 738 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work, which represents a major contribution to the literature for those interested in spiders or more generally in biological control and crop protection. Spiders are among the most omnipresent and numerous predators in both agricultural and natural ecosystems, and without them insect pest populations would go out of control. Their potential as biological control agents can only be appreciated though a greater understanding of their abundance and species composition in different ecological systems. There is a great need for literature providing guidance on spider identification. This volume provides a comprehensive illustrated guide to the spider fauna of rice in South and Southeast Asia. It is designed to be used by both specialists and novices.The majority of the species covered were collected from a diversity of habitats in the Philippines. The bulk of the book consists of keys to the identification of families, genera, and species of Philippine spiders, illustrated by more than 1,000 line drawings, and 92 color photographs. A total of 341 species belonging to 134 genera within 26 families are recognized. Of these, 257 species and 8 genera are new to science. Also provided are distribution maps for individual species and a classification scheme for Philippine riceland spiders.
