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.

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 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.

This second part of Volume 48 of the Flora of Pan-Himalaya is devoted to the single genus, Saussurea of the Asteraceae family, which has wide medicinal applications. This is the largest family in the Pan-Himalaya, with 235 species, 149 of which are endemic to the Pan-Himalaya. Saussurea is a notoriously difficult, largely Asiatic, genus with often indistinct species boundaries. Many new species of Saussurea were described in the course of preparing this account. The nomenclatural novelties in this volume include five changes in status, and 17 new synonyms. 27 lectotypes are newly designated. During the research for this volume, the author and his team described 40 new species of Saussurea, and these, along with numerous new designations and classifications, are recorded here for the first time.

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.

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.

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.
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. Cultivation notes are included for those genera known tobe in hobbyist collections. Genera are beautifully illustrated with line drawings and color photographs.

This book is the most up to date work on honeycreepers, covering the life history, relationships, and biology of the birds. The honeycreepers, with their bright colouration, and canary-like songs, are famed for their unique evolutionary history as a geographically isolated group that has undergone a spectacular burst of adaptions to the islands of the Hawaiian archipelago.

Evolution is unlike any other theory in science in the generality of its interest and the excellence of the authors who write about it. This anthology contains extracts from over 60 scientific papers, by authors such as Stephen Jay Gould, Richard Dawkins, Francis Crick and Jacques Monod. It starts with Charles Darwin, but concentrates on modern research, including genomics - evolution's latest gusher of scientic insights. The extracts are organized in sections, enabling the reader to sample a range of views on each topic, such as how new species arise, or the significance of adaptive design in living things. The extracts have been chosen for their readability as well as their scientific importance, making this book an enjoyable way to meet some of the greatest minds of our time, writing on the greatest idea of all time.

The book is the most in-depth account of the fossil skull anatomy and evolutionary significance of the 3.6-3.0 million year old early human species Australopithecus afarensis. Knowledge of this species is pivotal to understanding early human evolution, because 1) the sample of fossil remains of A. afarensis is among the most extensive for any early human species, and the majority of remains are of taxonomically inormative skulls and teeth; 2) the wealth of material makes A. afarensis an indispensible point of reference for the interpretation of other fossil discoveries; 3) the species occupies a time period that is the focus of current research to determine when, where, and why the human lineage first diversified into separate contemporaneous lines of descent. Upon publication of this book, this species will be among the most thoroughly documented extinct ancestors of humankind. The main focus of the book - its organizing principle - is the first complete skull of A. afarensis (specimen number A.L. 444-2) at the Hadar site, Ethiopia, the home of the remarkably complete 3.18 million year old skeleton known as "Lucy," found at Hadar by third author D. Johanson in 1974. Lucy and other fossils from Hadar, together with those from the site of Laetoli in Tanzania, were controversially attributed to the then brand new species A. afarensis by Johanson, T. White and Y. Coppens in 1978. However, a complete skull, which would have quickly resolved much of the early debate over the species, proved elusive until second author Y. Rak's discovery of the 444 skull in 1992. The book details the comparative anatomy of the new skull (and the cast of its brain, analyzed by R. Holloway and M. Huan) , as well as of other skull and dental finds recovered during the latest, ongoing field work at Hadar, and analyzes the evolutionary significance of A. afarensis in the context of other critically important discoveries of earliest humans made in recent years. In essence, it summarizes the state of knowledge about one of the central subjects of current paleoanthropological investigation.

Cephalopods are fast-moving, voracious predators, and can change colour with breath-taking rapidity. They range from the giant squid, the world's largest marine invertebrate, to species of only 2 cm in length. Inhabitants of most seas of the world, they are found from the surface to great depths. Most cephalopods have short lives yet their efficiency in capturing and consuming prey ensures rapid growth. These animals possess highly-developed nervous systems, large brains, elaborate senses, complex behaviour and are capable of learning. Many of these features are described and illustrated with line drawings and photomicrographs.

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.

This volume provides a comprehensive account of the systematic vegatative anatomy of the plant family Iridaceae. The iris family includes several horticulturally important genera, such as Iris Crocus, Gladiolus and Freesia, and many others of potential horticultural value. The book contains much original information, and places it in the context of the taxonomy and relationships of the plants concerned. It also summarizes the relevant literature. Like its predecessors in the Anatomy of the Monocotyledons series, Volume VIII: Iridaceae will be an essential reference work for students and professionals in botany and horticulture.

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.

The tropics with their lush rainforests are extremely rich in plant life but are still comparatively unknown. Botanists at the Royal Botanic Gardens, Kew have a long tradition of exploring and plant collecting in the tropics, accumulating an unsurpassed practical knowledge of the tropical plants they encounter. This second edition of The Kew Tropical Plant Families Identification Handbook brings together this knowledge in a guide to the commonly encountered and ecologically important plants of the tropics. Written by Kew's experts, this handbook is based on Kew's Tropical Plant Identification course, which uses classical morphology, as well as more simple 'spot' characters, to teach plant identification.

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.
