Book Description
Although they are highly intelligent, ruthless predators, carnivores are increasingly rare. From the dwarf mongoose to the polar bear, carnivores are at once respected and misunderstood, invoking both fear and curiosity in the humans with whom they share their world. Ronald M. Nowak celebrates these fascinating mammals in Walker's Carnivores of the World. This comprehensive guide, featuring 225 illustrations, covers the world's eight terrestrial families of carnivores. Each generic account comprises scientific and common names, number and distribution of species, physical attributes, measurements, hunting and social activity, reproduction, habitat, population dynamics, longevity, and status of threatened species. A thought-provoking overview by David W. Macdonald and Roland W. Kays is packed with results of the latest field and laboratory research on topics ranging from evolutionary history to the adaptive value of fur patterns. Emphasizing the interplay of social life, morphology, and predatory behavior, it provides an up-to-date panorama of the world's carnivores.

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
Bat biologist Barbara A. Schmidt-French and writer Carol A. Butler offer a compendium of insightful facts about bats in this accessible and expertly written question-and-answer volume. Numbering more than one thousand species in our world today, bats in the wild are generally unthreatening. Like most other mammals, bats are curious, affectionate, and even playful with one another. Highly beneficial animals, bats are critical to global ecological, economic, and public health. Do Bats Drink Blood? illuminates the role bats play in the ecosystem, their complex social behavior, and how they glide through the night sky using their acute hearingùecholocation skills that have helped in the development of navigational aids for the blind. Personal in voice with the perspective of a skilled bat researcher, this book explores wideranging topics as well as common questions people have about bats, providing a trove of fascinating facts. Featuring rare color and black-and-white photographs, including some by renowned biologist, photographer, and author Merlin Tuttle, Do Bats Drink Blood? provides a comprehensive resource for general readers, students, teachers, zoo and museum enthusiasts, farmers and orchardists, or anyone who may encounter or be fascinated by these extraordinary animals.

Book Description
This book focuses on central themes related to the conservation of bats. It details their response to land-use change and management practices, intensified urbanization and roost disturbance and loss. Increasing interactions between humans and bats as a result of hunting, disease relationships, occupation of human dwellings, and conflict over fruit crops are explored in depth. Finally, contributors highlight the roles that taxonomy, conservation networks and conservation psychology have to play in conserving this imperilled but vital taxon. With over 1300 species, bats are the second largest order of mammals, yet as the Anthropocene dawns, bat populations around the world are in decline. Greater understanding of the anthropogenic drivers of this decline and exploration of possible mitigation measures are urgently needed if we are to retain global bat diversity in the coming decades. This book brings together teams of international experts to provide a global review of current understanding and recommend directions for future research and mitigation.

Book Description
The world’s nearly 7,000 species of crabs are immediately recognizable by their claws, sideways movement, stalked eyes, and thick outer shells. These common crustaceans are found internationally, thriving in various habitats from the edge of the sea to the depths of the ocean, in fresh water or on land. Despite having the same basic body type as decapod crustaceans—true crabs have heavy exoskeletons and ten limbs with front pincer claws—crabs come in an enormous variety of shapes and sizes, from the near microscopic to the giant Japanese spider crab. In Walking Sideways, Judith S. Weis provides an engaging and informative tour of the remarkable world of crabs, highlighting their unique biology and natural history. She introduces us to recently discovered crabs such as the Yeti crab found in deep sea vents, explains what scientists are learning about blue and hermit crabs commonly found at the shore, and gives us insight into the lifecycles of the king and Dungeness crabs typically seen only on dinner plates. Among the topics Weis covers are the evolution and classification of crabs, their habitats, unique adaptations to water and land, reproduction and development, behavior, ecology, and threats, including up-to-date research. Crabs are of special interest to biologists for their communication behaviors, sexual dimorphism, and use of chemical stimuli and touch receptors, and Weis explains the importance of new scientific discoveries. In addition to the traditional ten-legged crabs, the book also treats those that appear eight-legged, including hermit crabs, king crabs, and sand crabs. Sidebars address topics of special interest, such as the relationship of lobsters to crabs and medical uses of compounds derived from horseshoe crabs (which aren’t really crabs). While Weis emphasizes conservation and the threats that crabs face, she also addresses the use of crabs as food (detailing how crabs are caught and cooked) and their commercial value from fisheries and aquaculture. She highlights other interactions between crabs and people, including keeping hermit crabs as pets or studying marine species in the laboratory and field. Reminding us of characters such as The Little Mermaid’s Sebastian and Sherman Lagoon’s Hawthorne, she also surveys the role of crabs in literature (for both children and adults), film, and television, as well in mythology and astrology. With illustrations that offer delightful visual evidence of crab diversity and their unique behaviors, Walking Sideways will appeal to anyone who has encountered these fascinating animals on the beach, at an aquarium, or in the kitchen.
