Book Description
In the year 2020 the world stopped and we were forced to do a quarantine that became a nightmare. We are already in 2022 and we are still counting the losses. Much of the neglect of the Brazilian government's management with education and science is already beginning to be forgotten. During the year 2020, I was reading and writing an analysis diary of the work “A vida de Galileo” by German author Bertolt Brecht for my second doctoral thesis in the area of literary theory at UNICAMP. The pandemic crisis invaded my reading analyzes of the work that are recorded in the diary I wrote in 1 year when we were wondering if we would have vaccines against COVID-19. The written diary served as the basis for the autoethnographic analysis of the thesis in literary theory of criticism of science and the life of scientists. The decision to publish the diary as a book has the same objective of making the noise of the flight of bats as in the short story “The companions: a blurry story” by the writer Caio Fernando Abreu. Abreu's tale is about a group of fellow political activists who gather in a house and remain completely silent. The only sounds that reach us readers are that of an analytical narrator present who tries to speak for each of those characters who cannot tell their stories; the other sound that all the characters can hear is that produced by the wings of bats that fly outside the house all the time, breaking the silence and disturbing that group of people. This leads us to think that the idea of publishing the diary is to encourage our bats to be very noisy and not to silence the memories. Here we present a bilingual version of the diary (Portuguese/English). Portuguese version: https://doi.org/10.5281/zenodo.6653200

Book Description
Explore the Everyday Lives of Bats! Bats have been misunderstood for generations, yet they are essential to a healthy ecosystem. From insect control to pollination services, we need bats more than most people know. Bat Basics separates fact from fiction in a fascinating, fun guide to the world’s only flying mammals. Author Karen Krebbs has been studying bats for more than 30 years. She lectures, teaches, and even trains government workers on the subject—and now she’s sharing her expertise with you. Learn the Bat Basics, such as how they use echolocation, why they hibernate, and what they eat. Discover bat myths that you probably thought were true. Find out how to bat-proof a house. Then turn to the field guide section, and identify a variety of common and important-to-know species. Projects, activities, and tips for helping the bat population round out this comprehensive guide. Get Bat Basics, and read all about why bats should be celebrated—not feared.

Book Description
It has been great fun to write this book, even though it has taken longer than planned, and occasionally been exasperating. The most difficult problem was deciding what to exclude among so many interesting things, because the available material usually exceeded the space. Because a book like this covers so many aspects, each component must be limited. This book is intended for graduate and undergraduate students as well as professional scientists who want to work with animal flight or to gain some insight into flight mechanics, aerodynamics, energetics, physiology, morpho logy, ecology and evolution. My aim has not been to give the whole mathe matical explanation of flight, but to provide an outline and summary of the main theories for the understanding of how aerofoils respond to an airflow. I also hope to give the reader some insight into how flight morphology and the various wing shapes have evolved and are adapted to different ecological niches and habitats.

Book Description
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.

Book Description
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.

Book Description
In recent years researchers have discovered that bats play key roles in many ecosystems as insect predators, seed dispersers, and pollinators. Bats also display astonishing ecological and evolutionary diversity and serve as important models for studies of a wide variety of topics, including food webs, biogeography, and emerging diseases. In Bat Ecology, world-renowned bat scholars present an up-to-date, comprehensive, and authoritative review of this ongoing research. The first part of the book covers the life history and behavioral ecology of bats, from migration to sperm competition and natural selection. The next section focuses on functional ecology, including ecomorphology, feeding, and physiology. In the third section, contributors explore macroecological issues such as the evolution of ecological diversity, range size, and infectious diseases (including rabies) in bats. A final chapter discusses conservation challenges facing these fascinating flying mammals. Bat Ecology is the most comprehensive state-of-the-field collection for scientists and researchers.

Book Description
Well adapted to numerous habitats, bats comprise almost one quarter of all species of mammals. This book is a comprehensive introduction to their biology. Suitable as a textbook for undergraduates and written by one of the world's leading researchers, the book offers an accessible summary of the extensive body of research on bats. The book takes a broad physiological perspective and devotes separate chapters to specific physiological systems as well as to bat ecology and phylogeny. It features a thorough discussion of echolocation, which continues to be the subject of intense research, and describes many European and neotropical bats, as well as North American species. "Biology of Bats" is an important resource both for students and researchers.
