Sperm Biology

Sperm Biology represents the first analysis of the evolutionary significance of sperm phenotypes and derived sperm traits and the possible selection pressures responsible for sperm-egg coevolution. An understanding of sperm evolution is fast developing and promises to shed light on many topics from basic reproductive biology to the evolutionary process itself as well as the sperm proteome, the sperm genome and the quantitative genetics of sperm. The Editors have identified 15 topics of current interest and biological significance to cover all aspects of this bizarre, fascinating and important subject. It comprises the most comprehensive and up-to-date review of the evolution of sperm and pointers for future research, written by experts in both sperm biology and evolutionary biology. The combination of evolution and sperm is a potent mix, and this is the definitive account. - The first review survey of this emerging field - Written by experts from a broad array of disciplines from the physiological and biomedical to the ecological and evolutionary - Sheds light on the intricacies of reproduction and the coevolution of sperm, egg and reproductive behavior

What is it like to be a swift, flying at over one hundred kilometres an hour? Or a kiwi, plodding flightlessly among the humid undergrowth in the pitch dark of a New Zealand night? And what is going on inside the head of a nightingale as it sings, and how does its brain improvise?Bird Sense addresses questions like these and many more, by describing the senses of birds that enable them to interpret their environment and to interact with each other. Our affinity for birds is often said to be the result of shared senses - vision and hearing - but how exactly do their senses compare with our own? And what about a birds' sense of taste, or smell, or touch or the ability to detect the earth's mag...

Ten Thousand Birds

A beautifully illustrated history of modern ornithology Ten Thousand Birds provides a thoroughly engaging and authoritative history of modern ornithology, tracing how the study of birds has been shaped by a succession of visionary and often-controversial personalities, and by the unique social and scientific contexts in which these extraordinary individuals worked. This beautifully illustrated book opens in the middle of the nineteenth century when ornithology was a museum-based discipline focused almost exclusively on the anatomy, taxonomy, and classification of dead birds. It describes how in the early 1900s pioneering individuals such as Erwin Stresemann, Ernst Mayr, and Julian Huxley rec...

Award-winning writer and ornithologist Tim Birkhead takes us on an epic and dazzling journey through this mutual history with birds. Since the dawn of human history, birds have stirred our imagination, inspiring and challenging our ideas about science, faith, art and philosophy, from the ibises mummified by Ancient Egyptians and Renaissance experiments on the woodpecker to the Victorian obsessions with egg collecting and our present fight to save endangered species. Weaving in stories from his own life as a scientist, this rich and fascinating book is the culmination of a lifetime's research and unforgettably shows how birds shaped us, and how we have shaped them. 'Thought-provoking at every turn, this inspiring, shocking, wonder-filled exploration of our relationship with birds' Isabella Tree, author of Wilding 'A fascinating book about the close and often surprising relationship between birds and people' Stephen Moss

The creation of Dolly the sheep in the 1990s was for many people the start of a new era: the age of genetically modified animals. However, the idea was not new for in the 1920s an amateur scientist, Hans Duncker, decided to genetically engineer a red canary. Though his experiments failed, they paved the way for others to succeed when it was recognised that the canary needed to be both a product of nature and nurture. This highly original narrative, of huge contemporary relevance, reveals how the obsession with turning the wild canary from green to red heralded the exciting but controversial developments in genetic manipulation.

The Most Perfect Thing

'I think that, if required on pain of death to name instantly the most perfect thing in the universe, I should risk my fate on a bird's egg' Thomas Wentworth Higginson, 1862 How are eggs of different shapes made, and why are they the shape they are? When does the shell of an egg harden? Why do some eggs contain two yolks? How are the colours and patterns of an eggshell created, and why do they vary? And which end of an egg is laid first - the blunt end or the pointy end? These are just some of the questions A Bird's Egg answers, as the journey of a bird's egg from creation and fertilisation to its eventual hatching is examined, with current scientific knowledge placed within an historical co...

The Wisdom of Birds

For thousands of years people have been fascinated by birds, and today that fascination is still growing. In 2007 bird-watching is one of the most popular pastimes, not just in Britain, but throughout the world, and the range of interest runs from the specialist to the beginner. In The Wisdom of Birds, Birkhead takes the reader on a journey that not only tells us about the extraordinary lives of birds - from conception and egg, through territory and song, to migration and fully flegded breeder - but also shows how, over centuries, we have overcome superstition and untested 'truths' to know what we know, and how recent some of that knowledge is. It was only in the nineteenth century that the ...

Sperm Competition and Sexual Selection

Sperm Competition and Sexual Selection presents the intricate ways in which sperm compete to fertilize eggs and how this has prompted reinterpretations of breeding behavior. This book provides a theoretical framework for the study of sperm competition, which is a central part of sexual selection. It also discusses the roles of females and the relationships between paternal care in sperm competition. The chapters focusing on taxonomic development are diverse and cover all the major animal groups, both vertebrate and invertebrate, and plants. The final chapter provides an overview discussing the relationship between sperm competition and sexual selection in terms of both function and mechanism and how these translate into species fitness. This book will be of prime interest to behaviorists, ecologists and evolutionary biologists, suggesting new avenues of research and new ways of approaching old problems.

Sperm competition is a central part of sexual selection and will therefore be of interest to all behavioral ecologists since the topics discussed here include many that are applicable to other animal groups. The text is supportedby numerous photographs, diagrams, tables, and outstanding illustrations by David Quinn. Sperm Competition in Birds addressess the following topics: Both functional and causal aspects of the subject The importance of sperm competition in different avian mating systems The relationship between sperm competition and male and female reproductive anatomy and physiology, copulation patterns, and paternity guards The costs and benefits of copulating with multiple partners for both males and females The relationship between multiple mating and paternity, and the far-reaching evolutionary consequences of sperm competition
