Описание: This book concentrates on the marine mammalian group of Odontocetes, the toothed whales, dolphins, and porpoises. In 23 chapters, a total of 40 authors describe general patterns of ethological concepts of odontocetes in their natural environments, with a strong bent towards behavioral ecology. Examples are given of particularly well-studied species and species groups for which enough data exist, especially from the past 15 years. The aim is to give a modern flavor of present knowledge of ethology and behavior of generally large-brained behaviorally flexible mammals that have evolved quite separately from social mammals on land. As well, the plight of populations and species due to humans is described in multiple chapters, with the goal that an understanding of behavior can help to solve or alleviate at least some human-made problems.

Описание: This book brings a unique perspective to animal movement studies because all studies come from African tropical environments where the great diversity, either biological and structurally (trees, shrubs, vines, epiphytes), present the animals with several options to fulfil their basic needs. These conditions have forced the evolution of unique movement patterns and ecological strategies. The book follows on our previous book “Movement Ecology of Neotropical Forest Mammals” but focuses on tropical African forests. Movement is an essential process in the life of all organisms. Animals move because they are looking for primary needs such as food, water, cover, mating and to avoid predators. Understanding the causes and consequences of animal movement is not an easy task for behavioural ecologists. Many animals are shy, move in secretive ways and are very sensible to human presence, therefore, studying the movements of mammals in tropical environments presents logistical and methodological challenges. However, researchers have recently started to be solved these challenges and exciting new information is emerging. In this book we are compiling a set of extraordinary studies where researchers have used new technology and the strongest methodological approaches to understand movement patterns in wild African forest mammals. This second book should inspire early career researchers to investigate wild mammal?s movements in some of the most amazing forest in the world: African tropical forests.

Описание:
Pocket Guide to the Mammals of Costa Rica is the first guide to provide comprehensive coverage of every currently known mammal species found in Costa Rica. From the Central American Silky Anteater to the West Indian Manatee, Fiona A. Reid and Gianfranco G?mez Zamora introduce readers to over 200 species inhabiting the country and its waters. This pocket guide features: • 60 plates with full-color illustrations and over 100 photographs • An illustrated introduction covering the history of mammalogy in Costa Rica, how to find mammals, and more • Up-to-date species accounts, range maps, and natural history vignettes Lavishly illustrated and highly portable, the Pocket Guide to the Mammals of Costa Rica is indispensable for biologists, eco-tourists, and naturalists eager to learn more about the mammalian fauna of this small but biologically rich country.
Описание: In 2003, a cadre of researchers set out to determine what combination of supplemental or natural nutrition and white-tailed deer population density would produce the largest antlers on bucks without harming vegetation. They would come to call this combination “the sweet spot.” Over the course of their 15-year experiment, conducted through the Caesar Kleberg Wildlife Research Institute at Texas A&M University–Kingsville, Timothy E. Fulbright, Charles A. DeYoung, David G. Hewitt, Don A. Draeger, and 25 graduate students tracked the effects of deer density and enhanced versus natural nutrition on vegetation conditions. Through wet years and dry, in a semiarid environment with frequent droughts, they observed deer nutrition and food habits and analyzed population dynamics. Containing the results of this landmark, longitudinal study, in keeping with the Kleberg Institute’s mission, this volume provides science-based information for enhancing the conservation and management of Texas wildlife.
Advanced White-Tailed Deer Management: The Nutrition–Population Density Sweet Spot presents this critical research for the first time as a reference for hunters, landowners, wildlife managers, and all those who work closely with white-tailed deer populations. It explains the findings of the Comanche-Faith Project and the implications of these findings for white-tailed deer ecology and management throughout the range of the species with the goal of improving management.

Описание: Sloth Bear: The Barefoot Bear of Sri Lanka synthesises the author's body of research and experiences while working on the subspecies of sloth bear in Sri Lanka. Accompanied by beautiful photographs, the book provides readers with access to scientific information of urgent conservation concern delivered in a non-technical style.Meet one of the most enigmatic animals of the lowland forests: the sloth bear. This book provides a wealth of resources and imagery on the biology, ecology, and behaviour of sloth bears; sloth bear habitat and the rising threats to it from human population growth; and the difficult relationship between humans and sloth bears.Written in an engaging and accessible style, this book is an essential and inspiring read for both professional ecologists and non-specialist readers interested in the challenges of large carnivore conservation and workable solutions for human-bear coexistence.Part of the proceeds from the sale of this book will go to the Bear Conservation Fund of the International Association for Bear Research and Management. The fund supports bear research activities and conservation projects to understand and sustain bear populations across the world.

Описание:
This monumental text-reference places in clear persepctive the importance of nutritional assessments to the ecology and biology of ruminants and other nonruminant herbivorous mammals. Now extensively revised and significantly expanded, it reflects the changes and growth in ruminant nutrition and related ecology since 1982.
Among the subjects Peter J. Van Soest covers are nutritional constraints, mineral nutrition, rumen fermentation, microbial ecology, utilization of fibrous carbohydrates, application of ruminant precepts to fermentive digestion in nonruminants, as well as taxonomy, evolution, nonruminant competitors, gastrointestinal anatomies, feeding behavior, and problems fo animal size. He also discusses methods of evaluation, nutritive value, physical struture and chemical composition of feeds, forages, and broses, the effects of lignification, and ecology of plant self-protection, in addition to metabolism of energy, protein, lipids, control of feed intake, mathematical models of animal function, digestive flow, and net energy.
Van Soest has introduced a number of changes in this edition, including new illustrations and tables. He places nutritional studies in historical context to show not only the effectiveness of nutritional approaches but also why nutrition is of fundamental importance to issues of world conservation. He has extended precepts of ruminant nutritional ecology to such distant adaptations as the giant panda and streamlined conceptual issues in a clearer logical progression, with emphasis on mechanistic causal interrelationships.
Peter J. Van Soest is Professor of Animal Nutrition in the Department of Animal Science and the Division of Nutritional Sciences at the New York State College of Agriculture and Life Sciences, Cornell University.

Описание: Large terrestrial mammalian herbivores play critical roles in ecosystems by acting as regulators of energy and nutrient cycles, modulators of plant community composition and grassland-woodland transitions, agents of seed dispersal, and as prey for large carnivores. Though large herbivores represent a prominent component of mammalian assemblages throughout South and Southeast Asia, little is known about their roles in ecosystems in the region. This volume presents, for the first time, a collection of studies on the ecology of the rich and diverse large herbivore assemblages of South and Southeast Asia. Prepared by experts on herbivores of the region, it covers a comprehensive range of topics, including their evolutionary history, behavioural, nutritional, and population ecology, patterns of diversity across environmental gradients, roles as seed dispersers and regulators of plant growth, community compositions, and their conservation in the face of hunting and global change.
