Book Description
To some potential readers of this book the description of Biological System atics as an art may seem outdated and frankly wrong. For most people art is subjective and unconstrained by universal laws. While one picture, play or poem may be internally consistent comparison between different art products is meaningless except by way of the individual artists. On the other hand modern Biological Systematics - particularly phenetics and cladistics - is offered as objective and ultimately governed by universal laws. This implies that classifications of different groups of organisms, being the products of systematics, should be comparable irrespective of authorship. Throughout this book Minelli justifies his title by developing the theme that biological classifications are, in fact, very unequal in their expressions of the pattern and processes of the natural world. Specialists are imbibed with their own groups and tend to establish a consensus of what constitutes a species or a genus, or whether it should be desirable to recognize sub species, cultivars etc. Ornithologists freely recognize subspecies and rarely do bird genera contain more than 10 species. On the other hand some coleopterists and botanists work with genera with over 1500 species. This asymmetry may reflect a biological reality; it may express a working practicality, or simply an historical artefact (older erected genera often contain more species). Rarely are these phenomena questioned.

Book Description
"This spectacular book does full justice to the Compositae (Asteraceae), the largest and most successful flowering plant family with some 1700 genera and 24,000 species. It is an indispensable reference, providing the most up-to-date hypotheses of phylogenetic relationships in the family based on molecular and morphological characters, along with the corresponding subfamilial and tribal classification. The 2009 work not only integrates the extensive molecular phylogenetic analyses conducted in the last 25 years, but also uses these to produce a metatree for about 900 taxa of Compositae. The book contains 44 chapters, contributed by 80 authors, covering the history, economic importance, character variation, and systematic and phylogenetic diversity of the family. The emphasis of this work is phylogenetic; its chapters provide a detailed, current, and thoroughly documented presentation of the major (and not so major) clades in the family, citing some 2632 references. Like the Compositae, the book is massive, diverse, and fascinating. It is beautifully illustrated, with 170 figures, and an additional 108 cladograms (all consistently color-coded, based on the geographic range of the included taxa); within these figures are displayed 443 color photographs, clearly demonstrating the amazing array of floral and vegetative form expressed by members of the clade." --NHBS Environment Bookstore.

Book Description
Sixteen volumes and one supplement have now appeared in the series known as Evolutionary Biology. The editors continue to seek critical re views, original papers, and commentaries on controversial topics. It is our aim to publish papers primarily of greater length and depth than those normally published by society journals and quarterlies. The editors make every attempt to solicit manuscripts on an international scale and to see that every facet of evolutionary biology-classical or modern-is cov ered. Manuscripts should be sent to anyone of the following: Max K. Hecht, Department of Biology, Queens College of the City University of New York, Flushing, New York 11367; Bruce Wallace, Department of Biology, Virginia Polytechnic Institute and State University, Blacksburg, Virginia 24061; Ghillean T.

Book Description
Biology has entered an era in which interdisciplinary cooperation is at an all-time high, practical applications follow basic discoveries more quickly than ever before, and new technologiesâ€"recombinant DNA, scanning tunneling microscopes, and moreâ€"are revolutionizing the way science is conducted. The potential for scientific breakthroughs with significant implications for society has never been greater. Opportunities in Biology reports on the state of the new biology, taking a detailed look at the disciplines of biology; examining the advances made in medicine, agriculture, and other fields; and pointing out promising research opportunities. Authored by an expert panel representing a variety of viewpoints, this volume also offers recommendations on how to meet the infrastructure needsâ€"for funding, effective information systems, and other supportâ€"of future biology research. Exploring what has been accomplished and what is on the horizon, Opportunities in Biology is an indispensable resource for students, teachers, and researchers in all subdisciplines of biology as well as for research administrators and those in funding agencies.

Book Description
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.

Book Description
Interest in land crabs has burgeoned as biologists have increasingly focused on the evolution of terrestriality. Before the publication of this volume in 1988, there had been no single comprehensive source of information to serve biologists interested in the diverse aspects of terrestrial decapod crustacean. Biology of the Land Crabs was the first synthesis of recent and long-established findings on brachyuran and anomuran crustaceans that have evolved varying degrees of adaptation for life on land. Chapters by leading researchers take a coordinated evolutionary and comparative approach to systematics and evolution, ecology, behaviour, reproduction, growth and molting, ion and water balance, respiration and circulation, and energetics and locomotion. Each discusses how terrestrial species have become adapted from ancestral freshwater or marine forms. With its extensive bibliography and comprehensive index, including the natural history of nearly eighty species of brachyuran and anomuran crabs, Biology of the Land Crabs will continue to be an invaluable reference for researchers and advanced students.
