Sexual Segregation In Ungulates

eBook Download

BOOK EXCERPT:

"This book is about the differing spatial distribution of males and females in species of hooved mammals. This behavior, wherein males and females live separately for long periods of time, has been observed in many species, but the causes of it remain uncertain"--

Sexual Segregation In Vertebrates

eBook Download

BOOK EXCERPT:

Males and females often differ in developmental patterns, adult morphology, ecology and behaviour, and in many mammals males are often larger. Size dimorphism results in divergent nutritional and energetic requirements or reproductive strategies by the sexes, which in turn sometimes causes them to select different forage, use different habitats, and express differing social affinities. Such divergent life-styles often lead males and females to live large parts of their lives separately. Sexual segregation is widespread in animals. Males and females may share the same habitat, but at different times, for example, or they might use different habitats entirely. Why did sexual segregation evolve and what factors contribute to it? Sexual Segregation in Vertebrates explores these questions by looking at a wide range of vertebrates and is aimed as a synthesis of our current understanding and a guide for future research.

The Social Gene

eBook Download

BOOK EXCERPT:

The hypothesis of animal interactions, known as kin selection or the selfish gene, proposes that only blood relatives are capable of forming herds and engaging in unselfish acts with each other. While this may satisfy the expectations of many evolutionists, the animals themselves frequently do not adhere to this restriction. There are several examples of animals in the wild assisting unrelated individuals at a cost to themselves and many also form colonies that contain unrelated individuals. In this monograph the author proposes a modification to the theory that renders the restriction of kin selection altogether unnecessary. Instead, he argues that the genes of animals that control social interactions, do not give instructions at all, but nudge the animals through combinations of rewards and penalties towards their best long-term interests in accord with the principles of Darwinian evolution. This exposition has been built on the many excellent published observations and experiments of researchers in the field and in the laboratory. It accounts for all general types of sociality of animals and humans including passive sociality, social exchange, sexual segregation, dispersal, adoption, mutual support, cooperation, altruism and human homosexuality.

Biology And Management Of White Tailed Deer

eBook Download

BOOK EXCERPT:

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.

Animal Homosexuality

eBook Download

BOOK EXCERPT:

Homosexuality is an evolutionary paradox in search for a resolution, not a medical condition in search for a cure. Homosexual behavior is common among social animals, and mainly expressed within the context of a bisexual sexual orientation. Exclusive homosexuality is less common, but not unique to humans. Poiani and Dixson invite the reader to embark on a journey through the evolutionary, biological, psychological and sociological aspects of homosexuality, seeking an understanding of both the proximate and evolutionary causes of homosexual behavior and orientation in humans, other mammals and birds. The authors also provide a synthesis of what we know about homosexuality into a biosocial model that links recent advances in reproductive skew theory and various selection mechanisms to produce a comprehensive framework that will be useful for anyone teaching or planning future research in this field.

Mountain Goats

eBook Download

BOOK EXCERPT:

Mountain goats have been among the least studied of North American ungulates, leaving wildlife managers with little information on which to base harvest strategies or conservation plans. This book offers the first comprehensive assessment of the ecology and behavior of mountain goats, setting forth the results of a remarkable 16-year longitudinal study of more than 300 marked individuals in a population in Alberta, Canada. The authors’ thorough, long-term study allowed them to draw important conclusions about mountain goat ecology—including individual reproductive strategies, population dynamics, and sensitivity to human disturbance—and to use those conclusions in offering guidance for developing effective conservation strategies. Chapters examine: -habitat use, vegetation quality, and seasonal movements -sexual segregation and social organization -individual variability in yearly and lifetime reproductive success of females -age- and sex-specific survival and dispersal -reproductive strategies and population dynamics -management and conservation of mountain goats The book also draws on the rich literature on long-term monitoring of marked ungulates to explore similarities and differences between mountain goats and other species, particularly bighorn sheep and ibex. By monitoring a marked population over a long period of time, researchers were able to document changes in sex-age structure and identify factors driving population dynamics. Because it explores the links between individual life-history strategy and population dynamics in a natural setting, Mountain Goats will be an invaluable resource for wildlife managers, researchers in ecology and animal behavior, conservationists, population biologists, and anyone concerned with the ecology and management of natural populations, especially in alpine environments.
