Predation and scavenging are pervasive ecological interactions in both terrestrial and aquatic environments. The ecology, evolution and conservation of predators and scavengers have received wide scientific attention and public awareness. However, the close connection that exists between predation and scavenging has not been emphasized until very recently. The recognition that carnivorous animals may obtain meat by either hunting prey or scavenging their carcasses has profound implications from individual behavior to population, community and ecosystem levels. However, many relevant questions still remain unexplored. This book deals with some of these questions, with the final aim to definitively dismiss the traditional view that predation and scavenging are disconnected ecological processes. This compendium of science may help to inspire ecologists, evolutionary biologists, paleontologists, anthropologists, epidemiologists, forensic scientists, anatomists, and, of course, conservation biologists in their stimulating and promising endeavor of achieving a more comprehensive understanding of carnivory in a rapidly changing world.
An intimate portrait of a mysterious and misunderstood animal. “Tjernshaugen writes in an easy-to-read style that is full of insight and understanding. I felt like I was sitting beside him as he described fox behavior.” —Rick McIntyre, Yellowstone wolf researcher and author of The Rise of Wolf 8 If you look into the fox's amber eyes, you'll notice vertical pupils. With such feline eyes in a slender canine body, the fox is a relative of the dog and the wolf, but it hunts alone, like a cat. The fox lives close to people, both in the city and in the country, but it’s wild, shy, and secretive. Taking long walks in the early morning, equipped with wildlife cameras—and sometimes with his...
The book offers a comparative look at the social strategies of five carnivorous social predators (four terrestrial and one marine) that make them successful hunting units. The focus is on mammalian predators hunting (largely) mammalian prey. Each chapter (with separate authors) devoted to a particular species, explores the versatile hunting techniques and social dynamics of these top predators as they attempt to survive, defend, and reproduce in challenging habitats. Each chapter also delves into how the social fabric and ecology of each species influence their ability to deal with natural and man-made threats and shifting baselines.
How perceptive are dogs to the good (or bad) behaviour of humans? How do they differ from breed to breed? Are some left handed and some right-handed? How can you tell if your pet is lonely? And just how similar is your dog to a wolf? In WHAT YOUR DOG IS THINKING the researcher, biologist and author Bo Söderström weaves together fascinating facts we're only just learning about man's best friends, with highly practical tips to help us better understand and care for the animals in our life. Research on dog behaviour and the complicated psychology which influences their responses and needs has formally exploded in the 21st century, with fascinating new knowledge gained every day. Bo Söderström has an iron grip on all the cutting edge research to match the most determined dog's hold on his favourite toy, and here he presents the most interesting results in an easy-to-understand way. Learn about the interaction between man and beast, understand your dog's mysterious signals, immerse yourself in those earliest moments, and gain the ability to stare into your animal's eyes and think 'I get you'.
Wolves on a wilderness island illuminate lessons on the environment, extinction, and life. For more than a quarter century, celebrated biologist John Vucetich has studied the wolves, and the moose that sustain them, of the boreal forest of Isle Royale National Park, an island in the northwest corner of Lake Superior. During this time, he has witnessed both the near extinction of the local wolf population, driven largely by climate change, and the intensely debated relocation of other wolves to the island in an effort to stabilize and maintain Isle Royale's ecosystem health. In Restoring the Balance, Vucetich combines environmental philosophy with field notes chronicling his day-to-day experi...
Contributors include recognized scientists and other wolf experts who introduce new and sometimes controversial findings. The World of Wolves included colour photographs of wild wolves by Peter A. Dettling, David C. Olson, and Robert J. Weselmann, and drawings by wildlife artist Susan Shimeld. --Book Jacket.
This volume offers a rich archaeological portrait of the human-canine connection. Contributors investigate the ways people have viewed and valued dogs in different cultures around the world and across the ages. Case studies from North and South America, the Arctic, Australia, and Eurasia present evidence for dogs in roles including pets, guards, hunters, and herders. In these chapters, faunal analysis from the Ancient Near East suggests that dogs contributed to public health by scavenging garbage, and remains from a Roman temple indicate that dogs were offered as sacrifices in purification rites. Essays also chronicle the complex partnership between Aboriginal peoples and the dingo and descr...
