Pages : 340
Book Description
For more than 300 years, the wolf was North America's most reviled beast, pursued to the brink of extinction throughout the United States. Then, within the last half-century, public opinion changed and the wolf became the symbol of the wilderness, tolerated and even desired over much of its former range. insert. 2 maps.

Mammalian Dispersal Patterns
Author: B. Diane Chepko-SadePublisher: University of Chicago Press
ISBN: 0226102688
Category : Nature
Languages : en
Pages : 361
Book Description
Mammalian Dispersal Patterns examines the ways that social structure affects population genetics and, in turn, rates of evolution, in mammalian groups. It brings together fieldwork in animal behavior and wildlife biology with theoretical work in demography and population genetics. The focus here is dispersal—whether, how, and when individuals leave the areas where they are born. Theoretical work in population genetics indicates that such social factors as skewed sex ratios, restrictive mating patterns, and delayed age of first reproduction will lower the reproductive variability of a population by reducing the number of genotypes passed from one generation to the next. Field studies have shown that many mammalian species do exhibit many such social characteristics. Among horses, elephant seals, and a number of primates, the majority of females are inseminated by only a fraction of the males. In pacts of wolves and mongooses, usually only the highest-ranking male and female breed in a given season. Although socially restricted mating tends to lower genetic variability in isolated populations, it actually tends to increase genetic variability in subdivided populations with low rates of migration between subunits. Among some species there is little dispersal and thus little gene flow between subpopulations; other species travel far afield before mating. The contributors to this volume examine actual data from populations of mammals, the way patterns of dispersal correlate with the genetic structure of individuals and populations, and mathematical models of population structure. This interdisciplinary approach has an important bearing on work in conservation of both wildlife and zoo populations, for it shows that the home range and the population size needed to maintain genetic variability can differ greatly from one species to the next. The volume also offers a fruitful model for future research.
Mammalian Predator Damage of Livestock
Author: The Behavioural Biology of Dogs
Author: Per JensenPublisher: CABI
ISBN: 1845931874
Category : Medical
Languages : en
Pages : 276
Book Description
Written by experts in different areas, this book presents an up-to-date account of the behavioral biology of dogs. Split in three parts, the book addresses the specific aspects of behavioral biology. The first part deals with the evolution and development of the dog, whereas the next part deals with basic aspects of dog behavior. The final part emphasizes on the behavioral problems, their prevention and cure.
