What main factors affect mammalian home range size and dynamics? To what extent do constraints on home range characteristics vary between the sexes? This book aims to address these issues by concentrating the authors' expertise and experience in studies of home ranges in general and focusing on their studies of black bears of the Pisgah Forest, North Carolina, in particular. The authors provide an overview of the black bears and methods for their study before discussing concepts of home range, developing predictive habitat quality models, addressing influences of food production on social organization and exploring the mating behaviour of male bears.

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.

The present biodiversity crisis is rife with opportunities to make important conservation decisions; however, the misuse or misapplication of the methods and techniques of animal ecology can have serious consequences for the survival of species. Still, there have been relatively few critical reviews of methodology in the field. This book provides an analysis of some of the most frequently used research techniques in animal ecology, identifying their limitations and misuses, as well as possible solutions to avoid such pitfalls. In the process, contributors to this volume present new perspectives on the collection, analysis, and interpretation of data. Research Techniques in Animal Ecology is an overarching account of central theoretical and methodological controversies in the field, rather than a handbook on the minutiae of techniques. The editors have forged comprehensive presentations of key topics in animal ecology, such as territory and home range estimates, habitation evaluation, population viability analysis, GIS mapping, and measuring the dynamics of societies. Striking a careful balance, each chapter begins by assessing the shortcomings and misapplications of the techniques in question, followed by a thorough review of the current literature, and concluding with possible solutions and suggested guidelines for more robust investigations.

The cougar is one of the most beautiful, enigmatic, and majestic animals in the Americas. Eliciting reverence for its grace and independent nature, it also triggers fear when it comes into contact with people, pets, and livestock or competes for hunters’ game. Mystery, myth, and misunderstanding surround this remarkable creature. The cougar’s range once extended from northern Canada to the tip of South America, and from the Pacific to the Atlantic, making it the most widespread animal in the western hemisphere. But overhunting and loss of habitat vastly reduced cougar numbers by the early twentieth century across much of its historical range, and today the cougar faces numerous threats as burgeoning human development encroaches on its remaining habitat. When Maurice Hornocker began the first long-term study of cougars in the Idaho wilderness in 1964, little was known about this large cat. Its secretive nature and rarity in the landscape made it difficult to study. But his groundbreaking research yielded major insights and was the prelude to further research on this controversial species. The capstone to Hornocker’s long career studying big cats, Cougar is a powerful and practical resource for scientists, conservationists, and anyone with an interest in large carnivores. He and conservationist Sharon Negri bring together the diverse perspectives of twenty-two distinguished scientists to provide the fullest account of the cougar’s ecology, behavior, and genetics, its role as a top predator, and its conservation needs. This compilation of recent findings, stunning photographs, and firsthand accounts of field research unravels the mysteries of this magnificent animal and emphasizes its importance in healthy ecosystem processes and in our lives.

What causes bear attacks? When should you play dead and when should you fight an attacking bear? What do we know about black and grizzly bears and how can this knowledge be used to avoid bear attacks? And, more generally, what is the bear’s future? Bear Attacks is a thorough and unflinching landmark study of the attacks made on men and women by the great grizzly and the occasionally deadly black bear. This is a book for everyone who hikes, camps, or visits bear country–and for anyone who wants to know more about these sometimes fearsome but always fascinating wild creatures.

Moths of the family Arctiidae, with their brilliant coloration, spectacular courtship rituals, and bizarre defenses, are wonders of the natural world. Unpalatable by virtue of secondary chemicals acquired from their hostplants, these moths advertise their defenses by their coloration and often mimic butterflies, wasps, bees, stinkbugs, and even cockroaches. They have ears with which they hear the echolocation of bats, and some answer with aposematic warnings, while some may jam the bats' sonar.This book, the first written on this fascinating group, documents how tiger moths and woolly bears-the adults and larvae of the Arctiidae-flourish in a world rife with predators, parasites, and competitors. The contributing authors' accounts, each written by a recognized expert in the field, weave together seminal studies on phylogeny and behavior, natural history, chemical communication, mate choice and sexual selection, chemical ecology, parasite-host relationships, self medication, animal orientation, predator-prey interactions, mimicry, adaptive coloration, speciation, biodiversity, and more.

Hidden Markov Models for Time Series: An Introduction Using R, Second Edition illustrates the great flexibility of hidden Markov models (HMMs) as general-purpose models for time series data. The book provides a broad understanding of the models and their uses. After presenting the basic model formulation, the book covers estimation, forecasting, decoding, prediction, model selection, and Bayesian inference for HMMs. Through examples and applications, the authors describe how to extend and generalize the basic model so that it can be applied in a rich variety of situations. The book demonstrates how HMMs can be applied to a wide range of types of time series: continuous-valued, circular, multivariate, binary, bounded and unbounded counts, and categorical observations. It also discusses how to employ the freely available computing environment R to carry out the computations. Features Presents an accessible overview of HMMs Explores a variety of applications in ecology, finance, epidemiology, climatology, and sociology Includes numerous theoretical and programming exercises Provides most of the analysed data sets online New to the second edition A total of five chapters on extensions, including HMMs for longitudinal data, hidden semi-Markov models and models with continuous-valued state process New case studies on animal movement, rainfall occurrence and capture-recapture data
