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 cloning of the SRY gene and the attainment of XX mice transgenic for the Sry gene opened a new era in research on sex determination. This book surveys current knowledge of sex chromosomes and sex determination in all vertebrate classes, relying on the restriction of genetic recombination in sex chromosomes as the unifying concept of this subject. The book's interdisciplinary approach integrates contributions from the fields of cytogenetics, molecular biology, developmental biology, and evolutionary genetics. A detailed treatment of the meiotic behavior of sex chromosomes is featured, and the entire text is supplemented by numerous schemes, drawings, and electron micrographs. The book will be valuable to general cytogeneticists, vertebrate zoologists, and veterinarian and medical practitioners interested in the foundations of sex determination and the current knowledge of sex chromosomes. It will also interest students in advanced undergraduate and graduate courses in these areas.

For all that science knows about the living world, notes David P. Barash, there are even more things that we don't know, genuine evolutionary mysteries that perplex the best minds in biology. Paradoxically, many of these mysteries are very close to home, involving some of the most personal aspects of being human. Homo Mysterious examines a number of these evolutionary mysteries, exploring things that we don't yet know about ourselves, laying out the best current hypotheses, and pointing toward insights that scientists are just beginning to glimpse. Why do women experience orgasm? Why do men have a shorter lifespan than women? Why does homosexuality exist? Why does religion exist in virtually every culture? Why do we have a fondness for the arts? Why do we have such large brains? And why does consciousness exist? Readers are plunged into an ocean of unknowns--the blank spots on the human evolutionary map, the terra incognita of our own species--and are introduced to the major hypotheses that currently occupy scientists who are attempting to unravel each puzzle (including some solutions proposed here for the first time). Throughout the book, readers are invited to share the thrill of science at its cutting edge, a place where we know what we don't know, and, moreover, where we know enough to come up with some compelling and seductive explanations. Homo Mysterious is a guide to creative thought and future explorations, based on the best, most current thinking by evolutionary scientists. It captures the allure of the "not-yet-known" for those interested in stretching their scientific imaginations.

This book is for those who enjoy that precarious and ever-changing zone where the sea meets the land and want to understand the birds that frequent this special habitat in Florida and the islands to the south. Author David Nellis reveals the birds found along the beaches, among the mangroves, even up the rocky Caribbean cliffs. From the many birds that may be encountered along the coast, Dr. Nellis has selected 72 of the most common ones, including a few that, though less abundant, capture our interest. Each bird has its own ecological niche--manifested by its nesting, feeding, roosting, and migration habits--and territorial competition between species is a constant. This book shows the great variety of specialization behaviors developed by these birds to adapt to this unique environment. Over 250 photographs, mostly by the author, show many features of these birds and their habits never before so fully illustrated.

Mitochondrial diseases are often hard to diagnose. From the time they were first researched without animal models, patients of mitochondrial diseases were of equal interest to both clinical and basic scientists. With the new research done, this book includes updates on the normal structure, function, and molecular biology of the mitochondrial respiratory chain, information on traditional diagnostical methodologies, and an overview of the diagnostic promise of new technologies. The hypermetabolism of Luft disease, although only seen twice, is also studied. There are critical reviews of symptoms and signs associated with syndromes, as well as updates on the genetic defects of either the mitochondrial or the nuclear genome responsible for many disorders.

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.
