This book was released on 1983 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The genus Zelotes is redefined to include those gnaphosids with a preening comb on metatarsi III and IV and an intercalary sclerite situated prolaterally between the tegulum and terminal apophysis on the male palp. The 58 known American species, found from Alaska and northern Canada to southern Mexico and Jamaica, are placed in three species groups with 13 subgroups. Cladograms, keys, diagnoses, descriptions, illustrations, scanning electron micrographs, locality records, and distribution maps are provided. The American species Z. fratris is removed from the synonymy of the European Z. subterraneus (C.L. Koch), but three other European species (Z. kodaensis Miller and Buchar, Z. pallidus (O.P.-Cambridge), and Z. nilicola (O.P.-Cambridge)) are newly recorded from America. Apparently introduced populations of the southwestern species Z. reformans Chamberlin are newly recorded from Peru and Hawaii. Eleven specific names are newly synonymized: Z. pallidenotatus Mello-Leitão with Eilica modesta Keyserling; Z. chicano Gertsch and Riechert with Z. lasalanus Chamberlin; Z. inheritus Kaston with Z. pullus (Bryant); Z. pullatus fox with Z. tuobus Chamberlin; Z. calvanisticus Chamberlin and Z. protestans Chamberlin, both with Z. monachus Chamberlin; Z. omissus Chamberlin with Z. perditus Chamberlin; Z. montereus Chamberlin with Z. discens Chamberlin; Z. nannus Chamberlin and Gertsch with Z. nannodes Chamberlin; Z. kodaensis Miller and Buchar with Z. puritanus Chamberlin; and Z. circumspectus (Simon) with Z. pallidus (O.P.-Cambridge). The males of Z. gynethus Chamberlin, Z. discens Chamberlin, Z. mayanus Chamberlin and Ivie, Z. monodens Chamberlin, and Z. reformans Chamberlin, and the females of Z. pullus (Bryant), Z. pseustes Chamberlin, Z. anglo Gertsch and Riechert, Z. petrophilus Chamberlin, and Z. nilicola (O.P.-Cambridge) are described for the first time. Thirty new species are described"--P. 99.

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 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.
