Book Description
Like gems flitting through the sky, hummingbirds attract our eye. But they are more than flash: they are critical pollinators in their ecosystems. Similarly in the darkness of night, nectar-feeding bats perform the same important ecological service as their colorful avian counterparts. Vertebrate pollinators like bats and birds are keystone species of the Sonoran Desert. Biologist Theodore H. Fleming uses these species—found in the desert around his home—to address two big questions dealing with the evolution of life on Earth: How did these animals evolve, and how did they coevolve with their food plants? A deeply thoughtful and researched dive into evolutionary history, Birds, Bats, and Blooms offers an engaging trip across evolutionary trajectories as it discusses nectar-feeding birds and bats and their coevolution as pollinators with flowering plants. The primary focus is on New World birds such as hummingbirds and their chiropteran counterparts (nectar-feeding bats in the family Phyllostomidae). It also discusses their Old World ecological counterparts, including sunbirds, honeyeaters, lorikeets, and nectar-feeding bats in the Pteropodidae family. Fleming also addresses the conservation status of these beautiful animals. Through engaging prose, Fleming pulls together the most recent research in evolutionary biology and pairs it with accounts of his personal interactions with bats and birds. His account includes fourteen color photographs taken by the author during his research trips around the world.

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."

Book Description
This book examines the biology of tuco-tucos (Ctenomys) from an evolutionary perspective. Historically, these subterranean rodents have long attracted the attention of scientists due to its remarkable chromosomes variability and rapid diversification. A wealth of knowledge on physiology, ecology, genetics, morphology, paleontology, and taxonomy has been documented in the last 70 years through numerous single publications. In this volume, expert investigators review and frame these essays with the breadth of current understanding. The collection of chapters are presented into the major topics: i) Evolution of Ctenomys, ii) Geographic Patterns, iii) Organismal Biology, and iv) Environmental Relationships. Given its scope, the book will be of interest to both students and researchers and may stimulate further research with this exciting model on a wide range of evolutionary topics.

Book Description
This book brings together the latest information on tropical ungulates in different Latin American countries. These animals are not only important from the point of view of their role in different ecosystems, but also have cultural value for people. The book also discusses topics such as habitat transformation and hunting as these species are an important source of food in many places. Addressing ungulate natural communities in diverse ecosystems and countries, the book provides information on specific aspects of each of the most representative species, and highlights topics to help readers better understand these species and develop effective management and conservation strategies. The information presented also reveals the need for more knowledge and will hopefully provide the incentive for continued studies on this important group of animals. This publication serves as a reference for academic research on ungulate ecology, behavior and dynamics, as well as the basis for conservation strategies.

Book Description
Fully updated and revised, this is the bestselling comprehensive bilingual identification guide to Mexico’s diverse mammalian fauna. A remarkable achievement that took over 30 years to construct, Keys for Identifying Mexican Mammals is the only complete identification guide to Mexico’s mammalian fauna. Fully updated and revised, this bestselling book follows a bilingual arrangement, with identical information presented in Spanish and English on facing pages. The dichotomous presentation is both easy to follow and flawlessly compiled, including updated and expanded material that surpasses any previously available resource. Hundreds of diagnostic images are dispersed throughout the book, many showing minute details that differentiate one species from another, and introductory materials carefully explain the use of diagnostic features. The heart of the book, though, is the keys themselves, which cover every taxa—from artiodactyls and carnivores to primates and rodents—while allowing confident identification at the species level for both field and museum use. The book closes with appendices that cover preparation of specimens, a glossary, and a bibliography. Anyone with an interest in the mammalian fauna of Mexico, or mammals in general, will find this one-of-a-kind book an indispensable reference to Mexico’s rich diversity of wildlife.

Book Description
One hundred and five species of mammals are native to the Trans-Pecos region of Texas. The greatly varied terrain, climate, and vegetation make its mammalian life exceptionally varied, ranging from tiny shrews to great elks, from bats to aquatic beavers and muskrats, from desert-dwelling kangaroo rats to forest-loving chipmunks, and from an assortment of mice and rats to predatory cougars and coyotes. This fully revised and updated edition of The Mammals of Trans-Pecos Texas provides a guide to the identification of these animals and summarizes important facts about their lives. With nearly every species illustrated with accurate, detailed pen-and-ink drawings by artist Chester O. Martin and color plates of some of the most iconic mammals that live in the Trans-Pecos region, it exemplifies how biologists integrate art with science to develop a wider appreciation for nature. The account of each species is arranged to contain a brief description of the animal, the geographic distribution of the species, and a discussion of the natural history of the mammal. This authoritative work brings together an appreciation for and understanding of the diversity of fauna, life histories, and ecologies within a unique and fascinating landscape.

Book Description
Winner of the Wildlife Society Outstanding Edited Book Award for 2013! Winner of the Texas Chapter of The Wildlife Society Outstanding Book Award for 2011! Winner of a CHOICE Outstanding Academic Title Award for 2011! Biology and Management of White-tailed Deer organizes and presents information on the most studied large mammal species in the world. The book covers the evolutionary history of the species, its anatomy, physiology, and nutrition, population dynamics, and ecology across its vast range (from central Canada through northern South America). The book then discusses the history of management of white-tailed deer, beginning with early Native Americans and progressing through management by Europeans and examining population lows in the early 1900s, restocking efforts through the mid 1900s, and recent, overabundant populations that are becoming difficult to manage in many areas. Features: Co-published with the Quality Deer Management Association Compiles valuable information for white-tailed deer enthusiasts, managers, and biologists Written by an authoritative author team from diverse backgrounds Integrates white-tailed deer biology and management into a single volume Provides a thorough treatment of white-tailed deer antler biology Includes downloadable resources with color images The backbone of many state wildlife management agencies' policies and a featured hunting species through much of their range, white-tailed deer are an important species ecologically, socially, and scientifically in most areas of North America. Highly adaptable and now living in close proximity to humans in many areas, white-tailed deer are both the face of nature and the source of conflict with motorists, home-owners, and agricultural producers. Capturing the diverse aspects of white-tailed deer research, Biology and Management of White-tailed Deer is a reflection of the resources invested in the study of the species’ effects on ecosystems, predator-prey dynamics, population regulation, foraging behavior, and browser physiology.
