Studies of animal behavior often assume that all members of a species exhibit the same behavior. Geographic Variation in Behavior shows that, on the contrary, there is substantional variation within species across a wide range of taxa. Including work from pioneers in the field, this volume provides a balanced overview of research on behavioral characteristics that vary geographically. The authors explore the mechanisms by which behavioral differences evolve and examine related methodological issues. Taken together, the work collected here demonstrates that genetically based geographic variation may be far more widespread than previously suspected. The book also shows how variation in behavior can illuminate both behavioral evolution and general evolutionary patterns. Unique among books on behavior in its emphasis on geographic variation, this volume is a valuable new resource for students and researchers in animal behavior and evolutionary biology.

Sparrows are as complicated as they are common. This is an essential guide to identifying 76 kinds, along with a fascinating history of human interactions with them. What, exactly, is a sparrow? All birders (and many non-birders) have essentially the same mental image of a pelican, a duck, or a flamingo, and a guide dedicated to waxwings or kingfishers would need nothing more than a sketch and a single sentence to satisfactorily identify its subject. Sparrows are harder to pin down. This book covers one family (Passerellidae), which includes towhees and juncos, and 76 members of the sparrow clan. Birds have a human history, too, beginning with their significance to native cultures and continuing through their discovery by science, their taxonomic fortunes and misfortunes, and their prospects for survival in a world with ever less space for wild creatures. This book includes not just facts and measurements, but stories--of how birds got their names and how they were discovered--of their entanglement with human history.

A Guide to the Identification and Natural History of the Sparrows of the United States and Canada provides comprehensive information on all the features that make possible identification of all 62 species of sparrows that occur in North America. The text gives detailed descriptions of the summer, winter, and juvenile plumages of each species, as well as comparisons with similar species. The species accounts are illustrated with range maps and superb line drawings showing behavioral postures and, where useful, fine features of tail feather patterns. The 27 color plates splendidly illustrate the various plumages of each species with the emphasis on the distinctive appearance of birds of different sex, age, and geographic regions. This beautiful and authoritative book is a must for the library of all keen birders living in and visiting North America. Species accounts include discussions of species': * Identification * Measurements * Voice * Habitat * Ecology * Nesting biology * Distribution * Taxonomy * Geographic variations * Historical and present status

Phenotypic Switching: Implications in Biology and Medicine provides a comprehensive examination of phenotypic switching across biological systems, including underlying mechanisms, evolutionary significance, and its role in biomedical science. Contributions from international leaders discuss conceptual and theoretical aspects of phenotypic plasticity, its influence over biological development, differentiation, biodiversity, and potential applications in cancer therapy, regenerative medicine and stem cell therapy, among other treatments. Chapters discuss fundamental mechanisms of phenotypic switching, including transition states, cell fate decisions, epigenetic factors, stochasticity, protein-based inheritance, specific areas of human development and disease relevance, phenotypic plasticity in melanoma, prostate cancer, breast cancer, non-genetic heterogeneity in cancer, hepatitis C, and more. This book is essential for active researchers, basic and translational scientists, clinicians, postgraduates and students in genetics, human genomics, pathology, bioinformatics, developmental biology, evolutionary biology and adaptive opportunities in yeast. - Thoroughly addresses the conceptual, experimental and translational aspects that underlie phenotypic plasticity - Emphasizes quantitative approaches, nonlinear dynamics, mechanistic insights and key methodologies to advance phenotypic plasticity studies - Features a diverse range of chapter contributions from international leaders in the field

Avian Genetics: A Population and Ecological Approach is a collection of papers that deals with the study of birds in relation to the synthetic theory of evolution. This book studies the ecology, demography, behavior, and geographical distribution of birds; the text also discusses quantitative, chromosomal, biochemical, and population genetics. Part I reviews the various genetic interactions, including an analysis of DNA sequence variation. The different and newer techniques are compared such as the works of Sibley, Quinn, and White. Part II describes the molding genetic variation and covers topics such as inbreeding; gene flow and the genetic structure of populations; non-random mating; and the process of selection in natural populations of birds. Part III covers actual genetic case histories, including quantitative ecological genetics of great tits; genetic evolution of house sparrows; and presentation of evidence for sexual selection by female choice in the Arctic Skua. This book also presents future research in subjects such as the neutrality-selection controversy or genetics and conservation. This text can be beneficial for ecologists, ornithologists, animal conservationists, and population biologists studying birds.

The Extended Specimen highlights the research potential for ornithological specimens, and is meant to encourage ornithologists poised to initiate a renaissance in collections-based ornithological research. Contributors illustrate how collections and specimens are used in novel ways by adopting emerging new technologies and analytical techniques. Case studies use museum specimens and emerging and non-traditional types of specimens, which are developing new methods for making biological collections more accessible and "usable" for ornithological researchers. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series documents the power of ornithological collections to address key research questions of global importance.

Advances in the Study of Behavior was initiated over 40 years ago to serve the increasing number of scientists engaged in the study of animal behavior. That number is still expanding. This volume makes another important "contribution to the development of the field" by presenting theoretical ideas and research to those studying animal behavior and to their colleagues in neighboring fields. This volume reflects many of the current themes in animal behavior including the evolution of social behavior, sexual selection and communication. It also reflects controversial topics on which the authors provide interesting, new insights. Advances in the Study of Behavior is now available online at ScienceDirect — full-text online from volume 30 onwards.

It is not often that a century of scholarly activity breaks conveniently into halves, but ornithology of the first half of the 20th century is clearly different from that of the second half. The break actually can be marked in 1949, with the appearance of Meyer and Schuz's Ornithologie ais Biologische Wissenschaft. Prior to this, ornithologists had tended to speak mostly to other ornithologists, experiments (the testing of hy potheses) were uncommon, and a concern for birds as birds was the dominant thread in our thinking. Subsequent to 1949, ornithologists have tended to become ever more professional in their pursuits and to incorporate protocols of experimental biology into their work; more importantly perhaps, they have begun to show a concern for birds as agencies for the study of biology. Many of the most satisfying of recent ornithological studies have come from reductionist research ap proaches, and have been accomplished by specialists in such areas as biochemistry, ethology, genetics, and ecology. A great many studies routinely rely on statistical hypothesis testing, allowing us to come to conclusions unmarred by wishful thinking. Some of us are ready to tell the world that we are a "hard" science, and perhaps that time is not so very far off for most of us. Volume 2 examines several solid examples of late 20th-century ornithology.

Based on the approach laid out in the 1950s by Nobel laureate Nikolaas Tinbergen, this book looks at animal communication from the four perspectives of mechanisms, ontogeny, function, and phylogeny.
