The field of plant taxonomy has transformed rapidly over the past fifteen years, especially with regard to improvements in cladistic analysis and the use of new molecular data. The second edition of this popular resource reflects these far-reaching and dramatic changes by adding more than 3,000 new references and figures. Synthesizing current research and trends, this book now provides the most up-to-date overview of plant taxonomy in relation to monographic, biodiversity, and evolutionary studies, and continues to be an essential resource for students and scholars.

This volume introduces students to the philosophical and theoretical aspects of plant taxonomy. The text is divided into two parts: Part 1 explains the principles of taxonomy, including the importance of systematics, characters, concepts of categories, and different approaches to biological classification. Part 2 outlines the different types of data used in plant taxonomic studies with suggestions on their efficacy and modes of presentation and evaluation. This section also lists the equipment and financial resources required for gathering each type of data. References throughout the book illuminate the historical development of taxonomic terminology and philosophy while citations offer further study. More than just a reference, "Plant Taxonomy" is also a personal story of what it means to be a practicing taxonomist and to view these activities within a meaningful conceptual framework. Tod F. Stuessy recalls the progression of his own work and thoughts and shares his belief that the most creative taxonomy is done by those who have a strong conceptual grasp of their own research.

How do radically new kinds of organisms evolve? The Origin of Higher Taxa addresses this essential question, specifically whether the emergence of higher taxa such as orders, classes, and phyla are the result of normal Darwinian evolution acting over a sufficiently long period of time, or whether unusual genetic events and particular environmental and ecological circumstances are also involved. Until very recently, the combination of an incomplete fossil record and a limited understanding about how raw mutations lead via modified ontogenic processes to significant phenotypic changes, effectively stymied scientific debate. However, it is now timely to revisit the question in the light of the discovery of considerable new fossil material (and new techniques for studying it), together with significant advances in our understanding of phenotypic development at the molecular level. This novel text incorporates evidence from morphology, palaeobiology, developmental biology, and ecology, to review those parts of the fossil record that illustrate something of the pattern of acquisition of derived characters in lineages leading to actual higher taxa as well as the environmental conditions under which they occurred. The author's original ideas are set within the context of a broad and balanced review of the latest research in the field. The result is a book which provides a concise, authoritative, and accessible overview of this fascinating subject for both students and researchers in evolutionary biology and palaeontology.

Have humans always waged war? Is warring an ancient evolutionary adaptation or a relatively recent behavior-and what does that tell us about human nature? In War, Peace, and Human Nature, editor Douglas P. Fry brings together leading experts in such fields as evolutionary biology, archaeology, anthropology, and primatology to answer fundamental questions about peace, conflict, and human nature in an evolutionary context. The chapters in this book demonstrate that humans clearly have the capacity to make war, but since war is absent in some cultures, it cannot be viewed as a human universal. And counter to frequent presumption the actual archaeological record reveals the recent emergence of war. It does not typify the ancestral type of human society, the nomadic forager band, and contrary to widespread assumptions, there is little support for the idea that war is ancient or an evolved adaptation. Views of human nature as inherently warlike stem not from the facts but from cultural views embedded in Western thinking. Drawing upon evolutionary and ecological models; the archaeological record of the origins of war; nomadic forager societies past and present; the value and limitations of primate analogies; and the evolution of agonism, including restraint; the chapters in this interdisciplinary volume refute many popular generalizations and effectively bring scientific objectivity to the culturally and historically controversial subjects of war, peace, and human nature.

Animal Evolution provides a comprehensive analysis of the evolutionary interrelationships and myriad diversity of the Animal Kingdom. It reviews the classical, morphological information from structure and embryology, as well as the new data gained from studies using immune stainings of nerves and muscles and blastomere markings which makes it possible to follow the fate of single blastomeres all the way to early organogenesis. Until recently, the information from analyses of gene sequences has tended to produce myriads of quite diverging trees. However, the latest generation of molecular methods, using many genes, expressed sequence tags, and even whole genomes, has brought a new stability to the field. For the first time this book brings together the information from these varied fields, and demonstrates that it is indeed now possible to build a phylogenetic tree from a combination of both morphology and gene sequences. This thoroughly revised third edition of Animal Evolution brings the subject fully up to date, especially in light of the latest advances in molecular techniques. The book is generously illustrated throughout with finely detailed line drawings and clear diagrams, many of them new.

For centuries orchids have been among the most popular of plant families, with thousands of species and hybrids cultivated worldwide for the diversity, beauty, and intricacy of their flowers.
The Genera Orchidacearum series represents a robust and natural classification of the orchids, something that has eluded plant scientists and orchid enthusiasts for years. The editors, who are all distinguished orchid specialists, incorporate a wealth of new DNA data into a truly phylogenetic classification, identifying the areas and taxa that merit additional work. To this end, they have invited several international specialists to contribute in their particular areas of expertise. Each volume provides comprehensive coverage of one or two orchid subfamilies and the series as a whole will be an indispensable reference tool for scientists, orchid breeders and growers.
Orchidaceae is the largest monocotyledon family and perhaps the largest plant family in terms of number of species, approximately 25,000. However, for a variety of reasons it remains one of the least understood. The fossil record is poor, and active research has been relatively scarce until recent years, in part because of the sheer size and cosmopolitan distribution of the family.
The fifth volume treats 186 genera in tribe Cymbidieae of the largest subfamily, Epidendroideae, including some of the showiest orchids often used in hybridizing. Comprehensive treatments are provided for each genus, which include complete nomenclature, description, distribution (with map), anatomy, palynology, cytogenetics, phytochemistry, phylogenetics, pollination, ecology, and economic uses. Cultivation notes are included for those genera known to be in hobbyist collections. Genera are beautifully illustrated with line drawings and colour photographs.

Animal life, now and over the past half billion years, is incredibly diverse. Describing and understanding the evolution of this diversity of body plans - from vertebrates such as humans and fish to the numerous invertebrate groups including sponges, insects, molluscs, and the many groups of worms - is a major goal of evolutionary biology. In this book, a group of leading researchers adopt a modern, integrated approach to describe how current molecular genetic techniques and disciplines as diverse as palaeontology, embryology, and genomics have been combined, resulting in a dramatic renaissance in the study of animal evolution.
The last decade has seen growing interest in evolutionary biology fuelled by a wealth of data from molecular biology. Modern phylogenies integrating evidence from molecules, embryological data, and morphology of living and fossil taxa provide a wide consensus of the major branching patterns of the tree of life; moreover, the links between phenotype and genotype are increasingly well understood. This has resulted in a reliable tree of relationships that has been widely accepted and has spawned numerous new and exciting questions that require a reassessment of the origins and radiation of animal life. The focus of this volume is at the level of major animal groups, the morphological innovations that define them, and the mechanisms of change to their embryology that have resulted in their evolution. Current research themes and future prospects are highlighted including phylogeny reconstruction, comparative developmental biology, the value of different sources of data and the importance of fossils, homology assessment, character evolution, phylogeny of major groups of animals, and genome evolution. These topics are integrated in the light of a 'new animal phylogeny', to provide fresh insights into the patterns and processes of animal evolution.
Animal Evolution provides a timely and comprehensive statement of progress in the field for academic researchers requiring an authoritative, balanced and up-to-date overview of the topic. It is also intended for both upper level undergraduate and graduate students taking courses in animal evolution, molecular phylogenetics, evo-devo, comparative genomics and associated disciplines.

Animal phylogeny is undergoing a major revolution due to the availability of an exponentially increasing amount of molecular data and the application of novel methods of phylogentic reconstruction, as well as the many spectacular advances in palaeontology and molecular developmental biology. Traditional views of the relationships among major phyla have been shaken and new, often unexpected, relationships are now being considered. At the same tiem, the emerging discipline of evolutionary developmental biology, or 'evo-devo', has offered new insights into the origin and evolvability of major traits of animal architecture and life cycle. All these developments call for a revised interpretation of the pathways along which animal structure and development has evolved since the origin of the Metazoa.
Perspectives in Animal Phylogeny and Evolution takes on this challenge, successfully integrating morphological, fossil and molecular evidence to produce a novel reinterpretation of animal evolution. Central to the book's approach is an 'evo-devo' perspective on animal evolution (with all the fresh insights this has given into the origin of animal organization and life cycles), complementary to the more traditional perspectives of pattern (cladistics, comparative anatomy and embryology), mechanisms (developmental biology) and adaptation (evolutionary biology). The author advocates the need to approach the study of animal evolution with a critical attitude towards many key concepts of comparative morphology and developmental biology. Particular attention in the book is paid to the evolution of life cycles and larval forms.
This accessible text is suitable for graduate students takingadvanced courses in evolutionary developmental biology, invertebrate zoology, molecular phylogenetics and palaeontology, as well as professional researchers in these fields requiring an authoritative and up-to-date overview of this dynamic topic.

Even before the publication of Darwin's Origin of Species, the perception of evolutionary change has been a tree-like pattern of diversification - with divergent branches spreading further and further from the trunk. In the only illustration of Darwin's treatise, branches large and small never reconnect. However, it is now evident that this view does not adequately encompass the richness of evolutionary pattern and process. Instead, the evolution of species from microbes to mammals builds like a web that crosses and re-crosses through genetic exchange, even as it grows outward from a point of origin. Some of the avenues for genetic exchange, for example introgression through sexual recombination versus lateral gene transfer mediated by transposable elements, are based on definably different molecular mechanisms. However, even such widely different genetic processes may result in similar effects on adaptations (either new or transferred), genome evolution, population genetics, and the evolutionary/ecological trajectory of organisms. For example, the evolution of novel adaptations (resulting from lateral gene transfer) leading to the flea-borne, deadly, causative agent of plague from a rarely-fatal, orally-transmitted, bacterial species is quite similar to the adaptations accrued from natural hybridization between annual sunflower species resulting in the formation of several new species. Thus, more and more data indicate that evolution has resulted in lineages consisting of mosaics of genes derived from different ancestors. It is therefore becoming increasingly clear that the tree is an inadequate metaphor of evolutionary change. In this book, Arnold promotes the 'web-of-life' metaphoras a more appropriate representation of evolutionary change in all lifeforms.

Systematics has developed rapidly during the past two decades. A multitude of new methods and contributions from a diversity of biological fields including molecular genetics and developmental biology have provided a wealth of phylogenetic hypotheses, some confirming traditional views others contradicting them. Despite such inconsistencies, it is now possible to recognize robust regions of a 'tree of life' and also to identify problematic areas which have yet to be resolved. This is the first book to apply the current state of phylogeny to an evolutionary interpretation of animal organ systems and body architecture, providing alternative theories in those cases of continuing controversy.
Organs do not appear suddenly during evolution; instead they are composed of far simpler structures. In some cases it is even possible to trace particular molecules or physiological pathways as far back as pre-animal history. What emerges is a fascinating picture, showing how animals have combined ancestral and new elements in novel ways to form constantly changing responses to environmental requirements.
The Evolution of Organ Systems starts with a general overview of current animal phylogeny, followed by review of general body organization including symmetry, anteroposterior axis, dorsoventral axis, germ layers, segmentation, and skeletons. Subsequent chapters then provide a detailed description of the individual organ systems themselves - integument, musculature, nervous system, sensory organs, body cavities, excretory system, circulatory system, respiratory system, intestinal system, gonads and gametes. Generously illustrated throughout, this accessible text is suitable for both upper levelundergraduate and graduate students taking courses in animal evolution, organogenesis, animal anatomy, zoology and systematics. It will also be a valuable reference tool for those professional researchers in these fields requiring an authoritative, balanced and up-to-date overview of the topic.

Ancestral sequence reconstruction is a technique of growing importance in molecular evolutionary biology and comparative genomics. As a powerful tool for testing evolutionary and ecological hypotheses, as well as uncovering the link between sequence and molecular phenotype, there are potential applications in a range of fields. Ancestral Sequence Reconstruction starts with a historical overview of the field, before discussing the potential applications in drug discovery and the pharmaceutical industry. This is followed by a section on computational methodology, which provides a detailed discussion of the available methods for reconstructing ancestral sequences (including their advantages, disadvantages, and potential pitfalls). Purely computational applications of the technique are then covered, including whole proteome reconstruction. Further chapters provide a detailed discussion on taking computationally reconstructed sequences and synthesizing them in the laboratory. The book concludes with a description of the scientific questions where experimental ancestral sequence reconstruction has been utilized to provide insights and inform future research. This research level text provides a first synthesis of the theories, methodologies and applications associated with ancestral sequence recognition, while simultaneously addressing many of the hot topics in the field. It will be of interest and use to both graduate students and researchers in the fields of molecular biology, molecular evolution, and evolutionary bioinformatics.

Bobcat: Master of Survival tells the story of the most adaptable and resilient wild feline in the world. While half the wild cat species worldwide are in danger, the bobcat is thriving, even expanding its range in North America. Why are bobcats flourishing when so many other wild felines are advancing towards extinction? The book explains how scientists apply the latest in wildlife research technology to probe this diminutive predator's habits and behavior. The reader is invited inside the bobcat's world to see how they hunt, kill prey, raise their young, coexist with humans, and deftly navigate the endless obstacles to survival.
The bobcat is both the most studied and the most exploited wild feline in the world. Millions have been killed for the fur trade. They were the focus of major controversy in the 1970s that transformed international conservation of wild felines. The book discusses how economics and politics play a far greater role in bobcat management and conservation than does science. Bobcat is the most comprehensive and up-to-date book on the natural history and management of bobcats to appear in 40 years.

This fourth volume treats the first 210 genera of the largest subfamily, Epidendroideae, including some of the showiest orchids often used in hybridizing. Comprehensive treatments are provided for each genus, which include complete nomenclature, description, distribution (with map), anatomy, palynology, cytogenetics, phytochemistry, phylogenetics, pollination, ecology, and economic uses.

Over-two thirds of the U.S. population is allergic to poison oak, poison ivy, or a related plant. These and many other common plants in our homes, fields, and gardens are irritants that cause misery to many. But surprisingly, there has never been a general guide to help raise awareness of them--and to help avoid them. This new book reviews the history, occurrence, classification, toxicity, and health aspects of all the major allergenic and irritant species.

Genera Orchidacearum is the first monograph of the world's orchid genera that reflects their long evolutionary history and reveals relationships based on genealogical descent and the most up-to-date DNA data.

The first complete treatment of the sedges of North America in more than half a century, this volume tackles the notoriously difficult to identify Cyperaceae with illustrations of all species in the group, emphasizing its great ecological importance. With extensive information on the more than 460 species of Carex, this third volume out of five covering the monocots of North America also includes 96 species of Cyperus, 68 species of Rhynchospora, 66 species of Eleocharis, and the monotypic, North American endemic Cymophyllus. The treatments--written and reviewed by experts--all contain identification keys, summaries of habitats and geographic ranges, distribution maps, pertinent synonymies, descriptions, chromosome numbers, and phenological information. Over 100 illustrations and 945 individual species distribution maps provide ecologists, applied biologists, and other readers with an authoritative account of the Cyperaceae.

The second of five volumes covering the monocots in North America north of Mexico, this volume features some of the most spectacular and showy native and naturalized species including orchids, lilies, irises, trilliums, hymenocallises, alliums, hostas, tulips, erythroniums, agaves, and yuccas. Plants representing eleven families following Cronquist's classification are in this work. The genus containing onions, garlic, and chives--Allium--is represented in the flora by almost 100 native and naturalized species. The Chicago native, Thismia americana, is one of five species in three genera of the mostly tropical Burmanniaceae, included in the volume, and four families (Aloaceae, Stmonaceae, Smilacaceae, and Dioscoreaceae) are each represented by single genera. With 112 illustrations and 1,138 individual species distribution maps, this thorough volume has identification keys, summaries of habitats and geographic ranges, distribution maps, pertinent synonymies, descriptions, chromosome numbers, phenological information, and other significant biological observations for each species.

This volume describes and illustrates the microscopic anatomy of the "aroids", the large, economically important plant family Araceae, and also the basal monocot family Acoraceae.

Latin is one of two acceptable languages for describing new plants, and taxonomists must be able to translate earlier texts in Latin. Providing a simple explanation of Latin grammar along with an in-depth vocabulary, this is an indispensable guide for systematic botanists worldwide. All relevant parts of speech are discussed, with accompanying examples as well as worked exercises for translating diagnoses and descriptions to and from Latin. Guidelines for forming specific epithets are also included. The authors cross-reference their grammar to Stearn's Botanical Latin and to articles in the International Code of Nomenclature for Algae, Fungi and Plants. The comprehensive vocabulary is enhanced with terms from recent glossaries for non-flowering plants - lichens, mosses, algae, fungi and ferns - making this an ideal resource for anyone looking to hone their understanding of Latin grammar and to translate botanical texts from the past 300 years.

The Insects has been the standard textbook in the field since the first edition published over forty years ago. Building on the strengths of Chapman's original text, this long-awaited 5th edition has been revised and expanded by a team of eminent insect physiologists, bringing it fully up-to-date for the molecular era. The chapters retain the successful structure of the earlier editions, focusing on particular functional systems rather than taxonomic groups and making it easy for students to delve into topics without extensive knowledge of taxonomy. The focus is on form and function, bringing together basic anatomy and physiology and examining how these relate to behaviour. This, combined with nearly 600 clear illustrations, provides a comprehensive understanding of how insects work. Now also featuring a richly illustrated prologue by George McGavin, this is an essential text for students, researchers and applied entomologists alike.

There is long-standing disagreement among systematists about how to divide biodiversity into species. Over twenty different species concepts are used to group organisms, according to criteria as diverse as morphological or molecular similarity, interbreeding and genealogical relationships. This, combined with the implications of evolutionary biology, raises the worry that either there is no single kind of species, or that species are not real. This book surveys the history of thinking about species from Aristotle to modern systematics in order to understand the origin of the problem, and advocates a solution based on the idea of the division of conceptual labor, whereby species concepts function in different ways - theoretically and operationally. It also considers related topics such as individuality and the metaphysics of evolution, and how scientific terms get their meaning. This important addition to the current debate will be essential for philosophers and historians of science, and for biologists.

The protein molecule is the basic building block of every living entity. Its deficiency leads to restricted growth and development of individuals. Globally, such malnutrition is on the rise due to various reasons such as rapid population growth, stagnation of productivity, and ever-rising costs. Millions of people, especially in developing and under-developed countries, suffer from protein malnutrition and the only possible solution is to encourage farmers to grow high-protein food legume crops in their fields for domestic consumption. This, however, could be possible if farmers are provided with new cultivars with high yield, and resistance to major insects, diseases, and key abiotic stresses. The major food legume crops are chickpea, cowpea, common bean, groundnut, lentil, pigeonpea, and soybean. Predominantly, the legume crops are grown under a subsistence level and, therefore, in comparison to cereals and horticultural crops their productivity is low and highly variable. The crop breeders around the globe are engaged in breeding suitable cultivars for harsh and changing environments but success has been limited and not up to needs. With the recent development of new technologies in plant sciences, efforts are being made to help under-privileged farmers through breeding new cultivars which will produce more protein per unit of land area. In this book, the contributors analyze the constraints, review new technologies, and propose a future course of crop breeding programs in seven cold and warm season legume crops.

In this second edition, all of the chapters have been updated and extensively revised to include recent advances in techniques and methods of analysis, and a separate chapter on the polymerase chain has been added. Each chapter emphasizes the conceptual background needed to understand the subject, and then provides a guide to collecting or analyzing data. Included are chapters on sampling design, collection and storage of tissues (a guide to major tissue collections has been added), each of the major molecule techniques, interspecific and phylogenetic analysis, and a review of applications. The technique chapters cover principles, assumptions, applications, limitations, and basic protocols for isozyme electrophoresis, molecular cytogenetics, DNA hybridization, the polymerase chain reaction (PCR), DNA fragments (including microsatellites and RAPDs), restriction sites analysis, cloning and nucleic acid sequencing. The chapters on analysis have been expanded to include the many new developments in techniques for analyzing molecular data, including an expanded discussion of maximum likelihood methods, methods for assessing the results, comparative methods, and models of molecular evolution.

Phylogenetic reconstruction--the method by which biologists examine the relationship between living and extinct organisms in an effort to identify evolutionary pathways--has seen radical changes in the last ten years. But as rapid advances in mathematical, molecular, developmental, and cladistic techniques have greatly improved reconstruction efforts, they have also sparked controversy, especially with regard to the assumptions and data underlying the cladistic method. This book brings together contributions from a wide range of practitioners in order to find common ground. By examining numerous models from a variety of fields, the book serves as a guide to the latest methods of classification and phylogeny reconstruction and provides insights into the relative merits that each approach has to offer. In particular, developmental studies emerge as a significant factor in cladogram construction. Splendidly written and wide-ranging in scope, Models in Phylogeny Reconstruction will be welcomed by students and researchers in systematic and evolutionary biology.

A systematic treatise on the Chrysididae, a globally distributed family of wasps, also known as gold wasps (for their bright metallic colours) or cuckoo wasps (for their parasitic habits). Some 3,000 valid species have been named and are arranged in 84 genera and 4 sub-families. This book is the first re-evaluation of their taxonomy since 1889 and its four main goals are: to provide a worldwide overview of the family, with re-classification of the generic and higher taxa; to summarize previously published information; to indicate problems in need of further study; to give detailed synonymic species lists for each genus, where synonymy refers to scientific names used in different nomenclature systems to designate the same species. Discussions for each tribe and sub-family include ancestral characteristics, phylogenetically important characters and a corresponding cladogram, keys to genera, and relationships amongst taxa. Generic discussions include generic synonymy and diagnostic features, relationships to other genera, and detailed species lists. The book should be of interest to entomologists, taxonomists and systematists, especially in academic departments, natural history museum

Tropical lichens are not only of interest in themselves but are of importance in the study of the ecosystems of which they are a part. Information on tropical lichens has not hitherto been readily available in book form, and the object of this volume is to synthesize what is known at present and to indicate areas where further research is needed. The material presented here is derived from a meeting held by the Systematics Association at which contributions were presented on the systematic, ecological, and biogeographical aspects of tropical lichens, together with the problems of their conservation. The resulting volume should thus be of value to a wide variety of scientists.
