Bioconservation And Systematics

This book is about phylogenetic diversity as an approach to reduce biodiversity losses in this period of mass extinction. Chapters in the first section deal with questions such as the way we value phylogenetic diversity among other criteria for biodiversity conservation; the choice of measures; the loss of phylogenetic diversity with extinction; the importance of organisms that are deeply branched in the tree of life, and the role of relict species. The second section is composed by contributions exploring methodological aspects, such as how to deal with abundance, sampling effort, or conflicting trees in analysis of phylogenetic diversity. The last section is devoted to applications, showing how phylogenetic diversity can be integrated in systematic conservation planning, in EDGE and HEDGE evaluations. This wide coverage makes the book a reference for academics, policy makers and stakeholders dealing with biodiversity conservation.

Conservation of the Earth's diversity is one of the most important and daunting challenges faced by biologists and politicians alike. The challenge has been taken up and declarations of intent issued, but there remains the basic problem of defining what we are trying to conserve, and why. This collection of essays reflects the wide range of views that are held about what constitutes biodiversity; from its perception in terms of species numbers, categorization of landforms, or different ecological levels, to the view that biodiversity is a dynamic and socio-political necessity for our own survival. The problems of matching species numbers, species variety, and the systematic hierarchy to geographic areas which we may wish to save are also addressed. Given that we need to set priorities for conservation, it is suggested that the preservation of the systematic hierarchy - as the most complete representation of the evolutionary legacy - should be the goal of conservation, and ways are outlined by which this may be accomplished.

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.

Most students who take a course in biological systematics do so to learn how to construct a data matrix and generate and evaluate a tree of phylogenetic relationships. Biological Systematics: Principles and Applications, by Randall T. Schuh, provides a welcome tool for these students and their instructors: it is a comprehensive and completely new textbook, the first of its kind since 1981. Systematics, the study of the reconstruction of the history of life, forms the underlying basis for organizing the knowledge of biology; cladistics is the diagrammatic method of charting phylogenetic relationships over time among evolving life forms. Cladistics analysis, the key tool used in this book, is also of great use outside pure systematic studies, and interests many students of population biology, ecology, epidemiology, and natural resources.Suitable for both graduate and advanced undergraduate students, Biological Systematics: Principles and Applications covers the core material for courses in biological systematics, with equal emphasis on both botany and zoology. It includes sections on the history and resources of the field; biological nomenclature; the theory of homology, character analysis, and computer algorithms; and the application of the results of systematic studies in the areas of biological classification, biogeography, adaptation and co-evolution, and biodiversity and conservation.

"This book presents an engaging and accessible examination of the role of systematic biology in species exploration and biodiversity conservation. Our planet and systematic biology are at a crossroads Millions of species face an imminent threat of extinction and with knowledge of only a fraction of earth's species, we are unprepared to respond. Species, Science and Society explains what is at stake if we continue to ignore the traditional mission of systematics. Rejecting claims that it is too late to document earth's species, that molecular evidence is sufficient, and that comparative morphology and the grand traditions of systematics are outdated, this book makes a compelling argument for a taxonomic renaissance. The book challenges readers to rethink assumptions about systematics. Shattering myths and misconceptions and clarifying the role of systematics in confronting mass extinction, it hopes to inspire a new generation of systematists. Readers are given a deeply personal view of the mission, motivations and rewards of systematic biology. Written in narrative style with passion, wit and optimism, it is the first book to question the growing dominance of molecular data, defend descriptive taxonomy and propose a mission to discover, describe and classify all species. Our evolutionary heritage, the fate of society and the future of the planet depend on what we do next. This book will be of great interest to academics, researchers and professionals working in systematics, taxonomy and biodiversity conservation, as well as students with a basic background in biology"--
