A revised and fully updated edition encourages the reader to view existing classification systems objectively as it reflects upon the rapid advances that have occurred since the first edition's publication.

Mosquitoes are undeniably one of the most studied groups of insects due to their great impact on human health as the agents that transmit the pathogens which cause malaria, filariasis and numerous viral diseases, such as yellow fever and dengue fever. The study of mosquitoes has given rise to a plethora of names for subspecies, species, subgenera, genera and family-level groups, many of which are duplicate names for the same entity. This unique volume is a comprehensive compilation of all scientific names introduced at all levels of classification within the family since the official start of zoological nomenclature. The work is largely a lexicon that is historical and informative as well as nomenclatural and bibliographic. Unlike catalogues, it contains sections devoted separately to the groups of names regulated by the International Code of Zoological Nomenclature, the species, genus and family groups, as well as sections concerned with names derived from personal and geographical names and other sources. In addition to insights into the history of mosquito classification, attention given to the formation, latinization and derivation of names makes the work a crucial contribution to mosquito science. Culicipedia is an important comprehensive reference source for students, entomologists, professional taxonomists and other scientists interested in culicid nomenclature, classification and the etymology of scientific names.

Taxonomy is an ever-changing, controversial and exCitmg field of biology. It has not remained motionless since the days of its founding fathers in the last century, but, just as with other fields of endeavour, it continues to advance in leaps and bounds, both in procedure and in philosophy. These changes are not only of interest to other taxonomists, but have far reaching implications for much of the rest of biology, and they have the potential to reshape a great deal of current biological thought, because taxonomy underpins much of biological methodology. It is not only important that an ethologist. physiologist. biochemist or ecologist can obtain information about the identities of the species which they are investigating; biology is also uniquely dependent on the comparative method and on the need to generalize. Both of these necessitate knowledge of the evolutionary relationships between organisms. and it is the science of taxonomy that can develop testable phylogenetic hypotheses and ultimately provide the best estimates of evolutionary history and relationships.

In Assembling Life, David Deamer addresses questions that are the cutting edge of research on the origin of life. For instance, how did non-living organic compounds assemble into the first forms of primitive cellular life? What was the source of those compounds and the energy that produced the first nucleic acids? Did life begin in the ocean or in fresh water on terrestrial land masses? Could life have begun on Mars? The book provides an overview of conditions on the early Earth four billion years ago and explains why fresh water hot springs are a plausible alternative to salty seawater as a site where life can begin. Deamer describes his studies of organic compounds that were likely to be available in the prebiotic environment and the volcanic conditions that can drive chemical evolution toward the origin of life. The book is not exclusively Earth-centric, but instead considers whether life could begin elsewhere in our solar system. Deamer does not propose how life did begin, because we can never know that with certainty. Instead, his goal is to understand how life can begin on any habitable planet, with Earth so far being the only known example.

This book, in three volumes, presents a detailed revision of the systematics and taxonomy of the platyhelminth class "Trematoda," subclasses "Aspidogastrea" and "Digenea," with keys for the identification of these parasites at the superfamily, family, subfamily and generic levels.The trematodes are parasitic worms infecting all vertebrate groups and include families of significance to human and animal health, with considerable economic impact. Volume 1 covers the subclass "Aspidogastrea" and order "Strigeida," while the second and third volumes will cover the orders "Echinostomida" and "Plagiorchiida."

We are a weird species. Like other species, we have a culture. But by comparison with other species, we are strangely unstable: human cultures self-transform, diverge, and multiply with bewildering speed. They vary, radically and rapidly, from time to time and place to place. And the way we live - our manners, morals, habits, experiences, relationships, technology, values - seems to be changing at an ever accelerating pace. The effects can be dislocating, baffling, sometimes terrifying. Why is this? In A Foot in the River, best-selling historian Felipe Fernandez-Armesto sifts through the evidence and offers some radical answers to these very big questions about the human species and its history - and speculates on what these answers might mean for our future. Combining insights from a huge range of disciplines, including history, biology, anthropology, archaeology, philosophy, sociology, ethology, zoology, primatology, psychology, linguistics, the cognitive sciences, and even business studies, he argues that culture is exempt from evolution. Ultimately, no environmental conditions, no genetic legacy, no predictable patterns, no scientific laws determine our behaviour. We can consequently make and remake our world in the freedom of unconstrained imaginations. A revolutionary book which challenges scientistic assumptions about culture and how and why cultural change happens, A Foot in the River comes to conclusions which readers may well find by turns both daunting and also potentially hugely liberating.

For many years orchids have been among the most popular of ornamental plants, with thousands of species and hybrids cultivated worldwide for the diversity, beauty, and intricacy of their flowers. This book is the eagerly-awaited result of over 30 years of research into orchid anatomy by one of the world's leading authorities and is the first comprehensive publication on orchid anatomy since 1930. It describes the structure and relationships among the cells and tissues of leaves, stems, and roots, and is organized systematically in line with the taxonomy expressed in the OUP Genera Orchidacearum Series. The book is fully illustrated with over 100 photomicrographs and numerous original line drawings. This latest addition to the Anatomy of the Monocotyledons Series is an essential reference text for orchid scientists and research students and will also be of interest and use to a broader audience of orchid enthusiasts.

A unique collection of concise but detailed information on 10,000 animals, plants, fungi and algae of the British Isles. Every species with an English common name is included. The compendium is in two parts. The first, smaller part, looks at various terms that people interested in natural history may come across. The second provides information on individual species or species groups, with entries on those with English (common) names, as well as selected families, orders, classes, etc. In the case of marine organisms, entries are given for intertidal and subtidal invertebrate species, and generally speaking for fish species that might be observed inshore. Indication is often given on distribution as well as whether a species is common, scarce or something in between. For some species a note is made of population size and trends. Comments are made where appropriate on etymology, both of the English name and the binomial. No other natural history dictionary or cognate publication relating to the British Isles is as comprehensive in taxonomic cover.

The field of molecular evolution has experienced explosive growth in recent years due to the rapid accumulation of genetic sequence data, continuous improvements to computer hardware and software, and the development of sophisticated analytical methods. The increasing availability of large genomic data sets requires powerful statistical methods to analyze and interpret them, generating both computational and conceptual challenges for the field.
Computational Molecular Evolution provides an up-to-date and comprehensive coverage of modern statistical and computational methods used in molecular evolutionary analysis, such as maximum likelihood and Bayesian statistics. Yang describes the models, methods and algorithms that are most useful for analysing the ever-increasing supply of molecular sequence data, with a view to furthering our understanding of the evolution of genes and genomes. The book emphasizes essential concepts rather than mathematical proofs. It includes detailed derivations and implementation details, as well as numerous illustrations, worked examples, and exercises. It will be of relevance and use to students and professional researchers (both empiricists and theoreticians) in the fields of molecular phylogenetics, evolutionary biology, population genetics, mathematics, statistics and computer science. Biologists who have used phylogenetic software programs to analyze their own data will find the book particularly rewarding, although it should appeal to anyone seeking an authoritative overview of this exciting area of computational biology.

This book presents current knowledge of the early vertebrates--mainly fish, but including some terrestrial creatures--which lived about 250 to 470 million years ago. The work focuses on anatomical and phylogenetic questions, but includes information on fossil discovery and preparation, as well as the analysis of the characteristics from which their relationships may be reconstructed. The author addresses both new and old problems in the evolution of certain anatomical details and deals briefly with the animals' way of life, extinction, and former distribution. The book is the first in its field to use a cladistic approach. For each major vertebrate group, the reader will find a diagram of relationships, or cladogram, with a selection of characters at each node, and a succinct phylogenetic classification.

Inspired by the pace of change in the taxonomy of the aerobic endospore-forming bacteria, the "Bacillus 2000" symposium on which this book is based was held in Bruges, Belgium, in August 2000, and was supported by the Federation of European Microbiological Societies, the Belgian Society for Microbiology, and several commercial sponsors. Bringing taxonomists interested in Bacillus and its relatives together with people who work with these organisms in medicine, agriculture, and industry, allowed those attending to appreciate the overlaps and interactions of their areas of expertise, in the absence of any comprehensive treatment of the current systematics of the group.

The meeting was a great success, and has resulted in the production of these proceedings, Applications and Systematics of Bacillus and Relatives, providing an up-to-date and comprehensive treatise on the classification, identification and applications of the aerobic endospore-forming bacteria; it is an essential reference for all microbiologists interested in these organisms.
Valuable reference work for all those interested in the systematics of Bacillus and its relatives.
Produced in response to the successful Bacillus 2000 meeting in Bruges and was supported by the Federation of European Microbiological Societies, the Belgian Society for Microbiology, and several commercial sponsors.
Of use to those working in fields as diverse as medicine, agriculture, food and industry.
Comprehensive and up-to-date analysis of the systematics of these organisms.
Includes the application of sophisticated chemotaxonomic and genetic characterization methods.

This text can be read at many levels. Not least it is an extraordinary inventory - an illustrated summary of all the Earthly creatures that have ever lived. Whatever living thing you come across, from E-coli to an oak tree or an elephant, this book will show you what kind of creature it is, and how it relates to all others. Yet there are far too many creatures to present merely as a catalogue. The list of species already described is vast enough - nearly two million - but there could in reality be as many as 30 million different animals, plants, fungi and protists - and perhaps another 400 million different bacteria and archaea. In the 4000 million years or so since life first began on Earth, there could have been several thousand billion different species. The only way to keep track of so many is to classify - placing similar creatures into categories, which nest within larger categories, and so on. As the centuries have passed, so it has become clear that the different groups are far more diverse than had ever been appreciated. Thus Linneus in the 18th century placed all living things in just two kingdoms, Animals and Plants.

Scaling relationships are a persistent theme in biology. Examples include branching patterns of blood vessels, structural and functional correlates of body size, distribution of body size and abundance among species, and variations in populations within an area or over time. This book, based on a conference at the Santa Fe Institute, brings together many of the most prominent workers in the area to assess our current understanding of scaling relationships at the physiological, biomechanical, and ecological levels.

Now that scientists can sequences genes with relative ease, the relationships among living organisms are becoming better known. Those relationships are summarized as phylogenetic trees. This book reveals how those trees can be used to give insights into diverse fields of biological enquiry including ecology, epidemiology, development, conservation, and the evolutionary process itself.

In his historical perspective on the changes in scientific thought over the last 100 years, Carl N. Degler explores the study of social evolution and the ongoing search for human nature. In Search of Human Nature provides a detailed perspective on the reasons behind the shifting emphasis in social thought from biology, to culture, and again to biology. Degler examines why these changes took place, the evidence and people fostering these changes and why students of human nature decided to accept this momentous change in thought. He suggests varying ideologies as the underlying force behind this shift in the study of social science. From Darwin's theory that human social behaviour has drastically evolved from animals, to the belief that human experience serves as the basic differentiating factor in humans, Degler provides a thorough and captivating examination of the roots of human behaviour.

An accessible and richly illustrated introduction to the natural history of dogs-from evolution, anatomy, cognition, and behavior to the relationship between dogs and humans As one of the oldest domesticated species, selectively bred over millennia to possess specific behaviors and physical characteristics, the dog enjoys a unique relationship with humans. More than any other animal, dogs are attuned to human behavior and emotions, and accordingly play a range of roles in society, from police and military work to sensory and emotional support. Selective breeding has led to the development of more than three hundred breeds that, despite vast differences, still belong to a single species, Canis familiaris. The Dog is an accessible, richly illustrated, and comprehensive introduction to the fascinating natural history and scientific understanding of this beloved species. Adam Miklosi, a leading authority on dogs, provides an appealing overview of dogs' evolution and ecology; anatomy and biology; behavior and society; sensing, thinking, and personality; and connections to humans. Illustrated with some 250 color photographs, The Dog begins with an introductory overview followed by an exploration of the dog's prehistoric origins, including current research about where and when canine domestication first began. The book proceeds to examine dogs' biology and behavior, paying particular attention to the physiological and psychological aspects of the ways dogs see, hear, and smell, and how they communicate with other dogs and with humans. The book also describes how dogs learn about their physical and social environments and the ways they form attachments to humans. The book ends with a section showcasing a select number of dog breeds to illustrate their amazing physical variety. Beautifully designed and filled with surprising facts and insights, this book will delight anyone who loves dogs and wants to understand them better.

Western philosophy and religion, James Rachels argues, have been shaken by the implications of Darwin's work, most notably the controversial idea that humans are simply a more complex kind of animal. Here, Rachels assesses a number of studies that suggest how closely humans are linked to other primates in behavior, and then goes on to show how this idea undercuts the work of many prominent philosophers.

Created from Animals offers a provocative look at how Darwinian evolution undermines many tenets of traditional philosophy and religion. Rachels begins by examining Darwin's own life and work, presenting an astonishingly vivid and compressed biography. We see Darwin's studies of the psychological links in evolution (such as emotions in dogs, and the "mental powers" of worms), and how he addressed the moral implications of his work, especially in his concern for the welfare of animals. Rachels goes on to present a lively and accessible survey of the controversies that followed in Darwin's wake, ranging from Herbert Spencer's Social Darwinism to Edward O. Wilson's sociobiology, and discusses how the work of such influential intellects as Descartes, Hume, Kant, T.H. Huxley, Henri Bergson, B.F. Skinner, and Stephen Jay Gould has contributed to--or been overthrown by--evolutionary science.

With this sweeping survey of the arguments, the philosophers, and the deep implications surrounding Darwinism, Rachels lays the foundations for a new view of morality. Virbrantly written and provocatively argued, Created from Animals offers a new perspective on issues ranging from suicide to euthanasia to animal rights.

Human Population Biology is a careful integration of the social and biological sciences, drawing on anthropology, biology, human ecology and medicine to provide a comprehensive understanding of how our species adapts to natural and man-made environments. The book's chapters fall into five parts. In Part I, techniques to adapt and apply large-scale demographic methods to smaller populations, particularly important for studying non-Western populations, are presented. In Part II, the relationship of medical genetics to human adaptability and patterns of disease epidemiology in small, non-Western populations are discussed. In Part III work capacity, climatic stress and nutrition are covered. In Part IV methods for growth assessment and prediction are presented and ageing is addressed. The final section, Part V, presents integrated case studies of human adaptation to high altitude, and patterns of modernization and stress resulting from cultural change.

While there have been controversial attempts to link conclusions from sociobiological studies of animal populations to humans, few behavioral scientists or anthropologists have made serious progress. In this work, Austin Hughes presents a unique and well-defined theoretical approach to human social behavior that is rooted in evolutionary biology and sociobiology, and which is additionally viewed as a direct continuation of the structural-functional tradition in anthropological research. Using mathematical and statistical techniques, Hughes applies the principles of kin selection theory--which states that natural selection can favor social acts that increase the fitness of both individuals and their relatives--to anthropological data. Among the topics covered are the subdivision of kin groups, selection of leaders in traditional societies, patronage systems, and the correspondence between social and biological kinship. The author concludes that patterns of concentration of relatedness are more important than average relatedness for predicting social behavior. He also shows that social interactions can often be predicted on the basis of common genetic interest in dependent offspring. The result is a major contribution to the field of behavioral biology.

How does death help us understand the living? Death is more than the last event of life; it is interwoven into our growth, development, protection against disease, and more. It influences the direction of entire species via the cycle of a lifespan, and it involves asking many fascinating questions. How do we differentiate between life and death, though? How do we know when a person, animal, or cell is really dead? How much grey area is there in the science? Why do we age? Can we do anything about it? Scientifically, there's much we can learn about a living thing from its cells. In all living things, cells seem to carry "death" gene programs. Some living organisms have created systems to use these to their own advantage. Humans, for example, use the death of specific cells to hone our immune system and to give us fingernails and hair. Perhaps the most dramatic use occurs during the metamorphosis of insects and frogs. Even single-celled organisms use "quorum sensing" to eliminate some cells to ensure the overall survival of their colony in harsh environments. Thus, there is more to death than just dying. This latest book from science writer Gary C. Howard ties together the many ways that death helps us understand life. He synthesizes the involvement and relation of cells, tissues, organisms, and populations, explaining what happens at the end of life. Between discussions about popular topics such as the ethics of extending life and cell regeneration, Howard also answers fascinating questions about life and death. The resulting book examines how the end of life is determined and what we can learn from this process.

Although the species is one of the fundamental units of biological classification, there is remarkably little consensus among biologists about what defines a species, even within distinct sub-disciplines. The literature of paleobiology, in particular, is littered with qualifiers and cautions about applying the term to the fossil record or equating such species with those recognized among living organisms. In Species and Speciation in the Fossil Record, experts in the field examine how they conceive of species of fossil animals and consider the implications these different approaches have for thinking about species in the context of macroevolution. After outlining views of the Modern Synthesis of evolutionary disciplines and detailing the development within paleobiology of quantitative methods for documenting and analyzing variation within fossil assemblages, contributors explore the challenges of recognizing and defining species from fossil specimens and offer potential solutions. Addressing both the tempo and mode of speciation over time, they show how with careful interpretation and a clear species concept, fossil species may be sufficiently robust for meaningful paleobiological analyses. Indeed, they demonstrate that the species concept, if more refined, could unearth a wealth of information about the interplay between species origins and extinctions, between local and global climate change, and greatly deepen our understanding of the evolution of life.

Positive psychologists focus on ways that we can advance the lives of individuals and communities by studying the factors that increase positive outcomes such as life satisfaction and happiness. Evolutionary psychologists use the principles of evolution, based on Darwin's understanding of life, to help shed light on any and all kinds of psychological phenomena. This book brings together both fields to explore positive evolutionary psychology: the use of evolutionary psychology principles to help people and communities experience more positive and fulfilling lives. Across eleven chapters, this book describes the basic ideas of both evolutionary and positive psychology, elaborates on the integration of these two fields as a way to help advance the human condition, discusses several domains of human functioning from the perspective of positive evolutionary psychology, and finally, looks with an eye toward the future of work in this emerging and dynamic field. Over the past few decades, evolutionary psychologists have begun to crack the code on such phenomena as happiness, gratitude, resilience, community, and love. This book describes these facets of the human experience in terms of their evolutionary origins and proposes how we might guide people to optimally experience such positive phenomena in their everyday lives.

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 taking advanced 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.
