Evolutionary History Of Bats

This book explores the rich evolutionary history of bats from multiple perspectives, presenting some of the most remarkable discoveries involving fossil bats.

Advances in morphological and molecular methods continue to uncover new information on the origin and evolution of bats. Presenting some of the most remarkable discoveries and research involving living and fossil bats, this book explores their evolutionary history from a range of perspectives. Phylogenetic studies based on both molecular and morphological data have established a framework of evolutionary relationships that provides a context for understanding many aspects of bat biology and diversification. In addition to detailed studies of the relationships and diversification of bats, the topics covered include the mechanisms and evolution of powered flight, evolution and enhancement of echolocation, feeding ecology, population genetic structure, ontogeny and growth of facial form, functional morphology and evolution of body size. The book also examines the fossil history of bats from their beginnings over 50 million years ago to their diversification into one of the most globally wide-spread orders of mammals living today.

The second largest order of mammals, Chiroptera comprises more than one thousand species of bats. Because of their mobility, bats are often the only native mammals on isolated oceanic islands, where more than half of all bat species live. These island bats represent an evolutionarily distinctive and ecologically significant part of the earth’s biological diversity. Island Bats is the first book to focus solely on the evolution, ecology, and conservation of bats living in the world’s island ecosystems. Among other topics, the contributors to this volume examine how the earth’s history has affected the evolution of island bats, investigate how bat populations are affected by volcanic eruptions and hurricanes, and explore the threat of extinction from human disturbance. Geographically diverse, the volume includes studies of the islands of the Caribbean, the Western Indian Ocean, Micronesia, Indonesia, the Philippines, and New Zealand. With its wealth of information from long-term studies, Island Bats provides timely and valuable information about how this fauna has evolved and how it can be conserved.

Bats are highly charismatic and popular animals that are not only fascinating in their own right, but illustrate most of the topical and important concepts and issues in mammalian biology. This book covers the key aspects of bat biology, including evolution, flight, echolocation, hibernation, reproduction, feeding and roosting ecology, social behaviour, migration, population and community ecology, biogeography, and conservation. This new edition is fully updated and greatly expanded throughout, maintaining the depth and scientific rigour of the first edition. It is written with infectious enthusiasm, and beautifully illustrated with drawings and colour photographs.

Recent advances in the study of bats have changed the way we understand this illusive group of mammals. This volume consist of 25 chapters and 57 authors from around the globe all writing on the most recent finding on the evolution, ecology and conservation of bats. The chapters in this book are not intended to be exhaustive literature reviews, but instead extended manuscripts that bring new and fresh perspectives. Many chapters consist of previously unpublished data and are repetitive of new insights and understanding in bat evolution, ecology and conservation. All chapters were peer-reviewed and revised by the authors. Many of the chapters are multi-authored to provide comprehensive and authoritative coverage of the topics.

The study of animal development has deep historical roots in codifying the field of evolutionary biology. In the 1940s evolutionary theory became engulfed by analyses of microevolutionary genetics and development became focused on mechanisms, forsaking the evolutionary implications of ontogeny. Recently, ontogeny has resurfaced as a significant component of evolutionary change and also of population and community dynamics. Ontogeny, Functional Ecology and Evolution of Bats is a reference work by bat biologists who emphasize the importance of understanding ontogeny in analyses of evolution and ecology. In addition, the developmental underpinnings of specialized morphology, physiology and behaviour are elucidated, and the strong influence of ecology on the ontological niche of juvenile bats is illustrated. This book is an essential reference, not only for bat biologists, but for anyone working in the fields of ecology, developmental biology, evolution, behaviour and systematics.

In Greek mythology, the chimera was a hybrid monster. Similarly, bats look like they have the body of a mouse, the face of a gargoyle or fox, and the wings of a pterosaur, giving rise to this book’s title. Evolution’s Chimera describes the amazing physical and behavioural adaptations of bats, using them to illustrate the processes of natural evolution. Bats comprise a quarter of all mammals in the world and are the only mammals that can fly. They occupy every landmass and almost every habitat on Earth. They make up the second-most diverse group of mammals on the planet, numbering more than 1 270 species. And they are among the oldest mammals. They are therefore ideal for the study of how evolution generates biological diversity. David Jacobs, an expert on bats currently researching animal evolution, gives an accessible account of evolution using bats as a case study, from adaptation, competition and evolutionary arms races to the role of sensory systems in the adaptation of species. He explores why bats hang upside down, why they are so small and the diversity of their diets, from insects to blood. Based on research done over the last 10 years this book provides a review of the latest research into evolution and biology, indicates what research still needs to be done and introduces new hypotheses for testing.

There are more than 1,300 species of bats—or almost a quarter of the world’s mammal species. But before you shrink in fear from these furry “creatures of the night,” consider the bat’s fundamental role in our ecosystem. A single brown bat can eat several thousand insects in a night. Bats also pollinate and disperse the seeds for many of the plants we love, from bananas to mangoes and figs. Bats: A World of Science and Mystery presents these fascinating nocturnal creatures in a new light. Lush, full-color photographs portray bats in flight, feeding, and mating in views that show them in exceptional detail. The photos also take the reader into the roosts of bats, from caves and mines to the tents some bats build out of leaves. A comprehensive guide to what scientists know about the world of bats, the book begins with a look at bats’ origins and evolution. The book goes on to address a host of questions related to flight, diet, habitat, reproduction, and social structure: Why do some bats live alone and others in large colonies? When do bats reproduce and care for their young? How has the ability to fly—unique among mammals—influenced bats’ mating behavior? A chapter on biosonar, or echolocation, takes readers through the system of high-pitched calls bats emit to navigate and catch prey. More than half of the world’s bat species are either in decline or already considered endangered, and the book concludes with suggestions for what we can do to protect these species for future generations to benefit from and enjoy. From the tiny “bumblebee bat”—the world’s smallest mammal—to the Giant Golden-Crowned Flying Fox, whose wingspan exceeds five feet, A Battery of Bats presents a panoramic view of one of the world’s most fascinating yet least-understood species.
