DOWNLOAD EBOOKPrimary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies.Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of "primary" sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions.In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.

DOWNLOAD EBOOKWhen it comes to bacterial disease, we are living in a state of false security. Antibiotics have indeed brought unprecedented health benefits, protection from and cure of bacterial diseases during the past 50 years. But there are ominous signs that the fortress and the defenses built on antibiotics are crumbling. They are crum bling because we wittingly or unwittingly created selective con ditions for the emergence of superior pathogens that can no longer be controlled by antibiotics. There are numerous warnings. After a long period of eclipse tuberculosis has now emerged as a serious threat unchecked by antibiotic treatment. Recent years have seen reports of cholera epidemics, of anthrax infections, of serious problems with Salmonella and even with E. coli, just to name a few. Mankind is in a race with microbial invaders. The challenge is to anticipate and respond to developments that affect the precarious balance between man and microbe. This will re quire new knowledge and it will take time for an effective appli cation of that knowledge.

DOWNLOAD EBOOKAn animal-by-animal guide that reveals the meaning behind each encounter we have with animals • Provides sophisticated psychological insight into encounters with more than 150 animals, birds, reptiles, insects, and aquatic life • Explores how animals reflect our inner world, drawing our attention to inner turmoil, relationship issues, spiritual growth, and the deepest needs of the soul • Explains how the meaning of each encounter depends on whether the animal was hunting, fleeing, hiding, or acting indifferent when sighted We each feel connections to animals in our own way. Some of us have pets. Others admire animals in the wild. Because the outer world often reflects our internal states and animals are highly sensitive to our energies, each encounter with an animal signals something about our inner world and innermost concerns. The spontaneous, surprising contacts are the telling ones: a sparrow landing next to you, a fox darting across the road, or a bee alighting on your hand. However, even regular encounters with our pets can draw attention to our inner world and what needs to be thought over and grappled with, from psychic turmoil and relationship issues to spiritual growth and the deepest needs of the soul. Providing sophisticated psychological insight into encounters with more than 150 animals, birds, reptiles, insects, and aquatic life, Regula Meyer explores the messages each animal provides for us on a personal level when we encounter them. She explains how the meaning of each encounter depends on whether the animal was hunting, fleeing, hiding, or acting indifferent when sighted. For example, a fleeing animal is prompting you to pursue a subject consciously, while a hiding animal tells you to patiently observe something and draw insights from it. The author shows how animal encounters in the wild cause us to contemplate the present moment and inspire the flow of our perceptions, leading us to meditate on important concerns we may be ignoring or unaware of. Pets and other animals we see every day act as intensifiers of the energy for which they stand. With this animal-by-animal guide, you can discover the deep meaning behind your encounters with animals and the messages they bring as oracles of our souls.
