Available in PDF, EPUB and Kindle. Book excerpt: This book explores the biological underpinnings of social systems from invertebrates to mammals, particularly humans. These social systems, the authors argue, represent fusions between the economic and reproductive interests of organisms. Their theory reinstates the importance of economics in social organizations of all types, moving away from the more prominent emphasis on reproductive biology at the core of sociobiology.

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.

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.

Book excerpt: An "Identification Manual" on the Amazonian Entomofauna for beginners and non-specialists has been demanded for many years. Most taxonomic literature on Neotropical Arachnida and Myriapoda is strictly descriptive, keys in translated and accepted textbooks are restricted to the higher taxa and first introductions to Amazonian arthropods refer to specific sampling sites and are mainly devoted to insects. And the other hand, taxonomical knowledge on Amazonian Arthropoda was much improved due to investigations for the last two decades, cooperatively between the National Institute for Amazonian Research and the Tropical Ecology Working Group at the Max-Planck-Institute for Limnology in Ploen/Germany
Download or read book Foundations of Phylogenetic Systematics written by Johann Wolfgang Wägele and published by . This book was released on 2005 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phylogeny inference and the classification of organisms are indispensable for all fields of biology. On the basis of a well corroborated tree of life it is possible to understand the evolution of structure and function, of genomes, of gene families, of cascades of developmental genes, and the origin of genes of medical importance. Ecologists need a stable classification of organisms to identify organisms, to find their correct names and thus further information on relevant species. This book offers an introduction to the theory of Phylogenetic Systematics and is a companion for all biologists who want to analyze morphological or molecular data with classical methods or with modern computer programs. The first part of the book explains the epistemological basis that is independent of the type of method used to construct phylogenetic trees. Unlike other empirical sciences, the estimation of data quality in phylogenetics is still little developed and very often neglected. Here a theoretical basis is presented that enables the systematist to assess critically and objectively the quality of different data sets and to make statements on the plausibility of results. This requires a conception of the notions of information content, probability of homology, probability of cognition, probability of events, the principle of parsimony, the differentiation of phenomenological and modelling methods. Willi Hennig's original method is compared with modern numerical systematics and an updated Hennigian procedure of data analysis is discussed. The difference between phenetic and phylogenetic cladistics is explained. Popular tools for data evaluation implemented in computer programs are explained including their axiomatic assumptions, sources of error and possible applications. For the more common tools the mathematical background is explained in a simple, easy-to-understand way.Johann-Wolfgang Wagele was until recently head of the Department for Animal Systematics (Lehrstuhl fur Spezielle Zoologie) at the University of Bochum and is now director of the Museum Alexander Koenig in Bonn (Germany). His main research interests are the taxonomy, phylogeny and biodiversity of Isopoda, which implies observations of life history, biogeography and ecology in combination with phylogeny inference. Further subjects include arthropod phylogeny and tools for explorative data analyses. The author is president of the Gesellschaft fur Biologische Systematik, a Central European society of systematists, and he is actively promoting biodiversity research.
