When Charles Darwin first proposed Sexual Selection Theory, he suggested two mechanisms: competition among males and choice by females. Although their importance is long established and extremely well understood, their mirror images have remained largely underappreciated; males also choose, and females also compete. The combination of male mate choice (MMC) and female competition (FC) may be one of the most overlooked yet important and intriguing phenomena in modern sexual selection theory. This novel text reviews our current understanding of MMC and FC, highlighting the important connections between them. It places both concepts in the context of related fields such as female choice, mating systems, and sexual selection theory more broadly. A truly holistic approach is provided which takes all the relevant elements into consideration, especially the relative roles of MMC and FC, female ornamentation, their evolutionary consequences, and their genetic basis. Considering male mate choice and female competition in this way as effectively two sides of the same coin creates a powerful paradigm for a more complete understanding of sexual selection. Male Choice, Female Competition, and Female Ornaments in Sexual Selection will be suitable for both graduate students and researchers interested in sexual selection from an evolutionary, psychological, and anthropological perspective. It will also appeal to a broader audience of behavioural ecologists and evolutionary psychologists.

Why does brain size vary so widely among vertebrate animal species? What role has natural selection played in shaping the structure and function of the vertebrate brain? This accessible book unravels the myriad adaptive explanations that have built up over decades, providing both a review and a critique of the work that has sought to explain which natural selection pressures have led to changes in brain size. Debate over the causes of variation in brain size, especially within extant humans and during the course of hominid evolution, has persisted for at least a couple of centuries. However, it was not until relatively recently that there has been sufficient data to allow a coherent (and taxonomically widespread) evolutionary perspective to emerge. The comparative approach employed by evolutionary biologists and behavioural ecologists has been particularly enlightening with regard to addressing variation in brain size. However, the extent to which correlational data - currently generated in some profusion - can provide a suitable explanation is not yet clear, and a constructively critical analysis of the relevant data is now timely. Five classes of selection pressure have formed the majority of explanations: ecology, technology, innovation, sex, and sociality. The book starts with a brief description of the difficulties of measuring both brain size and intelligence (cognition), before addressing the evidence for each of these five factors in turn. It argues that although ecology currently provides the most convincing explanation for variation in the size of brain regions, none of the factors yet offers a robust and compelling explanation for variation in whole brain size. The book concludes by looking forwards, suggesting the future steps necessary to reach such an explanation; steps that are challenging but now within reach. Adaptation and the Brain is suitable for graduate level students taking courses in animal behaviour and cognition, behavioural ecology, evolutionary ecology, psychology, and neuroscience as well as academics and professional researchers in these fields. The reader will not require a specific understanding of neuroscience, nor of the function of any particular brain region.

Whether through loss of habitat or cascading community effects, diseases can shape the very nature of the marine environment. Despite their significant impacts, studies of marine diseases have tended to lag behind their terrestrial equivalents, particularly with regards to their ecological effects. However, in recent decades global research focused on marine disease ecology has expanded at an accelerating rate. This is due in part to increases in disease emergence across many taxa, but can also be attributed to a broader realization that the parasites responsible for disease are themselves important members of marine communities. Understanding their ecological relationships with the environment and their hosts is critical to understanding, conserving, and managing natural and exploited populations, communities, and ecosystems. Courses on marine disease ecology are now starting to emerge and this first textbook in the field will be ideally placed to serve them. Marine Disease Ecology is suitable for graduate students and researchers in the fields of marine disease ecology, aquaculture, fisheries, veterinary science, evolution and conservation. It will also be of relevance and use to a broader interdisciplinary audience of government agencies, NGOs, and marine resource managers.

Anthrozoology, the study of human-animal interactions (HAIs), has experienced substantial growth during the past 20 years and it is now timely to synthesise what we know from empirical evidence about our relationships with both domesticated and wild animals. Two principal points of focus have become apparent in much of this research. One is the realisation that the strength of these attachments not only has emotional benefits for people, but confers health benefits as well, such that a whole area has opened up of using companion animals for therapeutic purposes. The other is the recognition that the interactions we have with animals have consequences for their welfare too, and thus impact on their quality of life. Consequently we now study HAIs in all scenarios in which animals come into contact with humans, whether as pets/companions, farm livestock, laboratory animals, animals in zoos, or in the wild. This topical area of study is of growing importance for animals in animal management, animal handling, animal welfare and applied ethology courses, and also for people within psychology, anthropology and human geography at both the undergraduate and postgraduate level. It will therefore be of interest to students, researchers, and animal managers across the whole spectrum of human-animal contact.

Paleozoology and Paleoenvironments outlines the reconstruction of ancient climates, floras, and habitats on the basis of animal fossil remains recovered from archaeological and paleontological sites. In addition to outlining the ecological fundamentals and analytical assumptions attending such analyzes, J. Tyler Faith and R. Lee Lyman describe and critically evaluate many of the varied analytical techniques that have been applied to paleozoological remains for the purpose of paleoenvironmental reconstruction. These techniques range from analyses based on the presence or abundance of species in a fossil assemblage to those based on taxon-free ecological characterizations. All techniques are illustrated using faunal data from archaeological or paleontological contexts. Aimed at students and professionals, this volume will serve as fundamental resource for courses in zooarchaeology, paleontology, and paleoecology.

This book relates the mechanical and structural properties of bone to its function in man and other vertebrates.

Pelagic tunicates are fascinating for their beauty, remarkable in most cases for their curious and even bizarre life cycles, and often notable for extraordinarily rapid growth. Furthermore, in recent years their major importance in the economy of the sea has been recognized. Although the now outdated encyclopaedic texts of the 1930s dealt with pelagic tunicates, the results of much subsequent physiological and ecological work have only appeared in scattered articles. This book is unique in giving a modern account of the biology of pelagic tunicates, with much new and unpublished information. Different chapters treat such topics as the ecological impact of salp blooms, locomotion by jet propulsion, the affinities of different groups, and the abundance and distribution of each group. Updated classification and identification keys to every pelagic tunicate now known are included. The Biology of Pelagic Tunicates will be useful to all plankton workers, and may perhaps stimulate ecologists, physiologists, and geneticists to begin work on a somewhat neglected group of animals that offer some unusual advantages for different kinds of study.

New discoveries of ancient vertebrates, filling in gaps in the fossilrecord, are quickly eroding the traditionally recognized differences between theprincipal groups of vertebrates -- for example, between dinosaurs and birds -- andradically changing our understanding of the evolutionary history of the major groupof animals to which our species belongs. This book describes this changingscientific landscape and contributes to the revolution in our knowledge of thedevelopmental mechanisms that underlie evolutionary transformation.

Walk near woods or water on any spring or summer night and you will hear a bewildering (and sometimes deafening) chorus of frog, toad, and insect calls. How are these calls produced? What messages are encoded within the sounds, and how do their intended recipients receive and decode these signals? How does acoustic communication affect and reflect behavioral and evolutionary factors such as sexual selection and predator avoidance?
H. Carl Gerhardt and Franz Huber address these questions among many others, drawing on research from bioacoustics, behavior, neurobiology, and evolutionary biology to present the first integrated approach to the study of acoustic communication in insects and anurans. They highlight both the common solutions that these very different groups have evolved to shared challenges, such as small size, ectothermy (cold-bloodedness), and noisy environments, as well as the divergences that reflect the many differences in evolutionary history between the groups. Throughout the book Gerhardt and Huber also provide helpful suggestions for future research.

Illustrated Key to Skulls of Genera of North American Land Mammals is a manual that contains illustrations of North American land mammals such as marsupials, shrews, bats, moles among many others. This manual is a well-illustrated key, useful for identifying mammals through cranial characteristics. It also contains line-drawings, and many photographs to aid in identifying related genera. The distribution, diversity, and characteristics of each order and family of land mammals found in North American and to the north of Mexico are briefly discussed. J. Knox Jones, Jr., has been a practicing mammalogist for more than 40 years. Currently he is a Paul Whitfield Horn Professor of Biological Sciences at Texas Tech and a Curator in the Museum there. Jones has authored or edited 14 books among is more than 350 publications, and has studied mammals on five continents. He is a past president of the American Society of Mammalogists and has been awarded the C. Hart Merriam Award, the H. H. T. Jackson Award, and Honorary Membership by that society. In 1992, he was selected as Texas Distinguished Scientist of the Year by the Texas Academy of Science, and was awarded the Donald W. Tinkle Research Excellence Award by the Southwestern Association of Naturalists. Richard W. Manning is a member of the faculty of Southwest Texas State University in San Marcos. He has authored more than 40 publications, most of which deal with mammals. Manning has had considerable instructional experience in laboratories in mammalogy, and has been cited for his excellence in teaching. He is also an avid field biologist, and thus has studied mammals in their natural habitats as well. Manning took most of the photographs used in this laboratory manual and made many of the line drawings.

The purpose of this book, now in its third edition, is to introduce the morphology of vertebrates in a context that emphasizes a comparison of structire and of the function of structural units. The comparative method involves the analysis of the history of structure in both developmental and evolutionary frameworks. The nature of adaptation is the key to this analysis. Adaptation of a species to its environment, as revealed by its structure, function, and reproductive success, is the product of mutation and natural selection-the process of evolution. The evolution of structure and function, then, is the theme of this book which presents, system by system, the evolution of structure and function of vertebrates. Each chapter presents the major evolutionary trends of an organ system, with instructions for laboratory exploration of these trends included so the student can integrate concept with example.

Functional approach to morphology--treatment is unique as to organization, thoroughness, and extent of biomechanical analysis.

How did flying birds evolve from running dinosaurs, terrestrial trotting tetrapods evolve from swimming fish, and whales return to swim in the sea? These are some of the great transformations in the 500-million-year history of vertebrate life. And with the aid of new techniques and approaches across a range of fields-work spanning multiple levels of biological organization from DNA sequences to organs and the physiology and ecology of whole organisms-we are now beginning to unravel the confounding evolutionary mysteries contained in the structure, genes, and fossil record of every living species. This book gathers a diverse team of renowned scientists to capture the excitement of these new discoveries in a collection that is both accessible to students and an important contribution to the future of its field. Marshaling a range of disciplines-from paleobiology to phylogenetics, developmental biology, ecology, and evolutionary biology-the contributors attack particular transformations in the head and neck, trunk, appendages such as fins and limbs, and the whole body, as well as offer synthetic perspectives. Illustrated throughout, Great Transformations in Vertebrate Evolution not only reveals the true origins of whales with legs, fish with elbows, wrists, and necks, and feathered dinosaurs, but also the relevance to our lives today of these extraordinary narratives of change.

Many marine biologists have concentrated on the species approach to the study of marine vertebrates. Although it has long been recognized that species interact, it has been far easier to study that interaction from the viewpoint of only one of the participants. Recently biologists have tried to study interactions from the viewpoint of all participants. Because of the high visibility of birds, it is easy to observe their interactions with other vertebrates such as fish, porpoises, and whales, but it is difficult to obtain quantitative data on their interactions. Seabirds and Other Marine Vertebrates, the only comprehensive examination of its kind, fills a particular niche: that of pulling together in one place the exciting current work in marine species interactions between seabirds and other marine vertebrates.The majority of essays in this work are structured to include a balance between literature review, original data, and synthesis. They concern obvious aspects of predation, competition, and commensalism. These topics relate directly to food acquisition and survival in a marine environment, and provide paradigms for the future study of marine birds and other organisms.Since man's encroachment in coastal and pelagic environments is increasing and poses a threat to marine birds, a volume elucidating various aspects of their interactions has multiple uses. As well as being of value to ornithologist, this work should be useful to other vertebrate biologists, behaviorists, ecologists and managers involved with coastal planning. It is a forerunner of things to come in marine biology.

The real Hans Spemann, German embryologist (1869-1941), developed a concept of embryonic induction through his experiments on early amphibian embryos which demonstrated neural induction by the primary organizer and evocation of the lens by the optic vesicle. For his discovery of the "organizer" he was awarded the Nobel Peace in Physiology and Medicine in 1935, while he was Professor of Zoology at Freiburg, Germany. In the twenties and early thirties Spemann's laboratory was a mecca for students and investigators entering the new field of experimental embryology.
