Sexual Segregation in Vertebrates available in PDF, EPUB and Kindle. 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.

Navara. This book was released on 2018-02-01. Choosing Sexes available in PDF, EPUB and Kindle. There is extensive evidence that vertebrates of all classes have the ability to control the sexes of the offspring they produce. Despite dramatic differences in the mechanisms by which different taxa determine the initial sex of offspring, each group has found its own way of adjusting offspring sex ratios in response to social and environmental cues. For example, stress is a well-known modulator of offspring sex in members of all groups studied to date. Food availability, and limitation in particular, is another common cue that stimulates biases in offspring sex ratios in a wide variety of species. Offspring sex can be adjusted at the primary level, which occurs prior to conception, or at the secondary level, during embryonic development. While the mechanistic pathways that ultimately result in sex ratio biases and the developmental time-points sensitive to those mechanisms likely differ among taxa, the key involvement of steroid hormones in the process of sex ratio adjustment appears to be pervasive throughout. This book reviews the systems of sex determination at play in different vertebrate groups, summarizes the evidence that members of all vertebrate taxa can facultatively adjust offspring sex, and discusses when and how these adjustments can take place.

Why does it benefit some male and female animals to live separately? Sexual segregation, wherein the sexes of a species live apart for long periods of time, has far-reaching consequences for the ecology, behavior, and conservation of hooved mammals, which are called ungulates. Award-winning researcher R. Terry Bowyer has spent the past four decades unravelling the causes and consequences of this perplexing phenomenon by studying ungulates and the large carnivores that prey upon them. In Sexual Segregation in Ungulates, Bowyer's critical, thought-provoking approach helps resolve long-standing disagreements concerning sexual segregation and offers future pathways for species and habitat conservation. He highlights important elements of the natural history of wild ungulate species, including bighorn sheep and elk. He then uses this perspective to frame and test hypotheses illuminating the motivations behind sexual segregation. He investigates the role of sexual segregation in mechanisms underpinning ungulate mating systems, sexual dimorphism, paternal behavior, and population dynamics. Bowyer's research spans ecosystems from deserts to the Arctic and involves most species of ungulates inhabiting the North American continent. He also provides a timely review of sexual segregation for species of plants and other animals, including humans. Covering definitions, theory, findings, and practical applications of related study, Bowyer describes the behavioral patterns related to sexual segregation, explains how to detect these patterns, and considers the implications of sexual segregation for new approaches to conservation and management of ungulates and other species of wildlife. This book is essential reading for scientists and all those interested in the conservation and management of species, including wildlife professionals, hunters, outdoor enthusiasts, and naturalists.

Download and read online ebook Ecology, Evolution and Behaviour of Wild Cattle write by Mario Melletti. This book was released on 2014-10-30. Ecology, Evolution and Behaviour of Wild Cattle available in PDF, EPUB and Kindle. Covering all thirteen species of wild cattle, Ecology, Evolution and Behaviour of Wild Cattle brings together the contributions of international leading experts on the biology, evolution, conservation status and management of the tribe Bovini, providing: • A comprehensive review of current knowledge on systematic, anatomy and ecology of all wild cattle species (chapters 1 to 8); • A clear understanding of the conservation status of each species and the gaps in our current knowledge (chapters 9 to 20); • A number of case studies on conservation activities and an investigation of some of the most threatened and poorly understood species (chapters 21 to 27). An invaluable resource for students, researchers, and professionals in behavioural ecology, evolutionary biology and conservation biology, this beautifully illustrated reference work reveals the extraordinary link between wild cattle and humans, the benefits some of these species have brought us, and their key roles in their natural ecosystems.
