Book Description
Bears have fascinated people since ancient times. The relationship between bears and humans dates back thousands of years, during which time we have also competed with bears for shelter and food. In modern times, bears have come under pressure through encroachment on their habitats, climate change, and illegal trade in their body parts, including the Asian bile bear market. The IUCN lists six bears as vulnerable or endangered, and even the least concern species, such as the brown bear, are at risk of extirpation in certain countries. The poaching and international trade of these most threatened populations are prohibited, but still ongoing. Covering all bears species worldwide, this beautifully illustrated volume brings together the contributions of 200 international bear experts on the ecology, conservation status, and management of the Ursidae family. It reveals the fascinating long history of interactions between humans and bears and the threats affecting these charismatic species.

Book Description
Offering extensive information on tardigrades, this volume begins with a chapter on the history of tardigrades, from the first description by Goeze in 1773, until 1929, when the most comprehensive monographic approach by E. Marcus was published. Tardigrades’ organ systems, including their integument, body cavity, digestive, muscular, nervous and reproductive systems, as well as their overall external morphology, are summarized in the second chapter. Subsequent chapters present the current state of knowledge on tardigrade phylogeny, biogeography, paleontology, cytology and cytogenetics. In addition, the book provides insights into the ecology of tardigrades in marine, freshwater and terrestrial habitats. The reproduction, development and life cycles are summarized and the extraordinary environmental adaptations of encystment and cyclomorphosis, desiccation tolerance, freezing tolerance and radiation tolerance are discussed in detail. Further chapters provide an overview of key approaches in molecular tardigrade studies and describe techniques for sampling and sample processing. The book closes with a list of tardigrade taxa up to a sub-generic level, including the type species of each genus, the numbers of lower taxa in each taxon, and the main environments in which the taxa were found. Given its depth of coverage, the volume offers an invaluable resource for scientists from various disciplines who plan to research tardigrades, and for all others who are interested in these fascinating animals.

Examined. In Ghost Bears, R. Edward Grumbine looks at the wide-ranging implications of this crisis and explains why our species-centered approach will ultimately fail to protect ecosystems and diversity. Using the fate of the endangered grizzly bear - the "ghost bear"--To explore the causes and effects of species loss and habitat destruction, Grumbine presents a clear assessment of the biodiversity crisis and introduces the new science of conservation biology.

Book Description
This volume reports on the encounters between hikers and wildlife on the Appalachian Trail. Based on narratives provided by trail hikers, it explores the ways in which humans relate to the animals with whom they temporarily share a home. With attention to the themes of pilgrimage, the changing perception of the animals encountered and reactions to them, risk, auditory experience, and a sense of wildness, the author considers the meaning constituted by nonhuman animals in the context of the walkers’ narrative journeys. A phenomenologically informed study of the ways in which people perceive wild animals when in an unmediated wilderness setting, how they navigate interactions with them, and how they experience living among them, Blogging Wildlife will appeal to scholars across the social sciences with interests in anthrozoology and human–animal relations.
