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
In this book, Gustavo G. Politis and Luis A. Borrero explore the archaeology and ethnography of the indigenous people who inhabited Argentina's Pampas and the Patagonia region from the end of the Pleistocene until the 20th century. Offering a history of the nomadic foragers living in the harsh habitats of the South America's Southern Cone, they provide detailed account of human adaptations to a range of environmental and social conditions. The authors show how the region's earliest inhabitants interacted with now-extinct animals as they explored and settled the vast open prairies and steppes of the region until they occupied most of its available habitats. They also trace technological advances, including the development of pottery, the use of bows and arrows, and horticulture. Making new research and data available for the first time, Politis and Borrero's volume demonstrates how geographical variation in the Southern Cone generated diverse adaptation strategies.

Book Description
Large Carnivores and the Conservation of Biodiversity brings together more than thirty leading scientists and conservation practitioners to consider a key question in environmental conservation: Is the conservation of large carnivores in ecosystems that evolved with their presence equivalent to the conservation of biological diversity within those systems? Building their discussions from empirical, long-term data sets, contributors including James A. Estes, David S. Maehr, Tim McClanahan, Andrès J. Novaro, John Terborgh, and Rosie Woodroffe explore a variety of issues surrounding the link between predation and biodiversity: What is the evidence for or against the link? Is it stronger in marine systems? What are the implications for conservation strategies? Large Carnivores and the Conservation of Biodiversity is the first detailed, broad-scale examination of the empirical evidence regarding the role of large carnivores in biodiversity conservation in both marine and terrestrial ecosystems. It contributes to a much more precise and global understanding of when, where, and whether protecting and restoring top predators will directly contribute to the conservation of biodiversity. Everyone concerned with ecology, biodiversity, or large carnivores will find this volume a unique and thought-provoking analysis and synthesis.

Book Description
From the largest terrestrial carnivore, the Polar Bear, to the tiny Least Weasel that can squeeze through a wedding ring, the true carnivores include some of the world's most charismatic, admired, feared and spectacular creatures. This fully updated second edition of Luke Hunter's comprehensive guide profiles all of the world's terrestrial carnivore species. Thoroughly updated throughout and covering recently described species, a detailed account describes each species' key identification characteristics, distribution and habitat, behaviour, feeding ecology, social patterns, life history statistics, conservation and the latest on classification. This edition also includes accurate distribution maps for each species. Colour plates by top wildlife artist Priscilla Barrett depict each species, with subspecies, colour variations and behavioural vignettes for many. There are also detailed line drawings of more than 230 skulls and 110 footprints.

Book Description
The information and activities in this resource book enhance children's knowledge and awareness about the components of a grassland environment, including physical and biological characteristics. Students will discover where grasslands are located on our planet. They will find out what features grasslands have in common, what types of organisms live there, and how they are adapted to survive. As they explore grassland organism adaptations, students will discover similarities and differences between living things in grasslands and those in other ecosystems. Activities that emphasize the ecology of plants and animals, food chains and food webs, and survival will enable students to relate the structure of living things to their roles in the ecosystem. Four transparencies (print books) or PowerPoint slides (eBooks) are included to engage students in discussion and reinforce the concepts presented in the book.

Book Description
Small Carnivores: Evolution, Ecology, Behaviour, and Conservation This book focuses on the 232 species of the mammalian Order Carnivora with an average body mass 21.5 kg. Small carnivores inhabit virtually all of the Earth's ecosystems, adopting terrestrial, semi-fossorial, (semi-)arboreal or (semi-)aquatic lifestyles. They occupy multiple trophic levels and therefore play important roles in the regulation of ecosystems, such as natural pest control, seed dispersal and nutrient cycling. In areas where humans have extirpated large carnivores, small carnivores may become the dominant predators, which may increase their abundance ("mesopredator release") to the point that they can sometimes destabilize communities, drive local extirpations and reduce overall biodiversity. On the other hand, one third of the world's small carnivores are threatened or near threatened with extinction. This results from regionally burgeoning human populations' industrial and agricultural activities, causing habitat reduction, destruction, fragmentation and pollution. Overexploitation, persecution and the impacts of introduced predators, competitors, and pathogens have also negatively affected many small carnivore species. Although small carnivores have been intensively studied over the past decades, bibliometric studies showed that they have not received the same attention given to large carnivores. Furthermore, there is huge disparity in how research efforts on small carnivores have been distributed, with some species intensively studied and others superficially or not at all. This book aims at filling a gap in the scientific literature by elucidating the important roles of, and documenting the latest knowledge on, the world's small carnivores. p"This is a book that has been needed for decades. It is the first compendium of recent research on a group of mammals which has received almost no attention before the early 1970s. This book covers a wide range of subdisciplines and techniques and should be considered a solid baseline for further research on this little-known group of highly interesting mammals. As our knowledge regarding how ecosystems function increases, then the valuable role of small carnivores and the necessity for their conservation should be regarded as of paramount importance. The topics covered in this book should therefore be of great interest not only to academics and wildlife researchers, but also to the interested layman."
