Arguably biosonar is one of the 'eye-opening' discoveries about animal behavior and the auditory systems of echolocators are front and center in this story. Echolocation by bats has proven to be a virtual gold mine for colleagues studying neurobiology, while providing many rich examples of its impact on other areas of bats' lives. In this volume we briefly review the history of the topic (reminding readers of the 1995 Hearing by Bats). We use a chapter on new findings in the phylogeny of bats to put the information that follows in an evolutionary context. This includes an examination of the possible roles of Prestin and FoxP2 genes and various anatomical features affecting bat vocalizations. We introduce recent work on the role of noseleafs, ears, and other facial components on the focusing of sound and collection of echoes.
Bats have long been the focus of fascination, and sometimes fear: they move faultlessly through the darkness and spend the day hanging upside down in gloomy caverns and cracks – most at home where humans are least comfortable. Bats also represent a hugely important, numerous and varied group, accounting for 20% of all mammal species worldwide. Covering their biodiversity, ecology and natural history, A Miscellany of Bats offers a hoard of insights into the lives of these creatures. For over a quarter of a century Brock Fenton and the late Jens Rydell collaborated on projects involving bats. Here they bring together a collection of stories and anecdotes about bat research, brought to life by stunning photographs of these animals in action. Key topics include flight and echolocation, diet and roosting habits, and the complex social lives of bats. Jens and Brock also address issues of conservation and the interactions between bats and people, ranging from matters of disease to bats’ role as symbols, and our fixation with vampire bats. They explore how echolocation and flight shape batkind, from their appearance to where they go and why. Overall, this book is an entertaining and personal vision of bats’ central place in the universe. More than 150 species are covered.
The Anthropocene is the "age of human influence", an epoch well known for its urban impact. More than half of all people already live in cities, and this proportion is expected to rise to almost 70 percent by 2050. Like other species in urban areas, bats must contend with the pressures of profound and irreversible land cover change and overcome certain unique challenges, such as the high density of roads, lights, glass, and free-ranging domestic animals. Research on urban bats in recent decades indicates that when it comes to urban life, some bats are synanthropes. In other words, although most species of bats are negatively impacted by urbanisation, many appear to not only succeed, but also thrive in cities and towns. This observation has inspired interesting questions about bats in relation to urbanisation. Which traits and behaviours equip bats for urban success? What features of urban areas increase the likelihood that bats will successfully persist there or even colonize new areas? And how does the success of urban bats affect co-habiting humans? Our book explores the interactions between bats and urban environments through case studies and reviews. Understanding how different species interact with urban environments can reveal potential opportunities to mitigate urban threats to bats and threats posed by bats to other urban organisms, including humans. With this book, we thus aspire to provide a knowledge base to help guide current and future efforts to conserve bats.

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.
Bats are dangerous to man. Right? Wrong. Here is the truth about chiroptera, the only mammals that fly, in a short, well-illustrated account based on solid research but intended for a general reader. Bats, of which there are about 850 species in the world, are maligned as carriers of rabies (largely untrue) and admired for their biosonar. Heir diversity is reflected in their diets: some eat fruit, some nectar and pollen, other fish, birds, frogs, or other bats. Although most eat insects, it is the three species of blood-feeding vampires which receive most public attention and around which much myth and superstition (and misconception) have evolved. In addition to their diet and habit, Fenton discusses their remarkable sonar sight, their reproduction, migration, patterns of behavior ? from hunting to mating ? parasites, enemies, and life span. (The current record is held by an Ontario Little Brown Bat which in 1980 had survived more than 30 years.) Man's attitude toward bats, his destruction of their habitats, and his use of pesticides have contributed to a sharp decline in the bat population in many parts of the world. Many biologists are becoming increasingly concerned about the survival of some species, but maintaining their numbers requires a change in people's attitudes. Just Bats will help. It will also tell the reader how to evict bats from his attic ? provided he knows how they got in.
"This book is timely, and it provides a well-researched, compact entry to this literature." Animal Behaviour Communication in the Chiroptera reviews the available information about communication in chiroptera including brilliant suggestions on the relationship of bat communication to the general subject of communication."
