This book is about disease and death. It is an ecologist's view of Darwin's vivid evocation of Nature, red in tooth and claw. An international team of authors examines broad patterns in the population biology of natural enemies, and addresses general questions about the role of natural enemies in the population dynamics and evolution of their prey. For instance, how do large natural enemies like wolves differ from small natural enemies like bacterial diseases in their effects on prey abundance? Is it better to chase after prey, or sit and wait for it to come to you? How should prey behave in order to minimize the risk of being eaten? The answers are all in this fascinating senior undergraduate/postgraduate text.

What explains variance in the policy of Great Powers toward drug traffickers, pirates, and terrorists? Does counterharm policy depend just on the degree of material harm caused to a powerful state by such nonstate actors, or do normative, moral, and emotional factors also play a role? Why did the U.S., for example, harshly punish al Qaeda after 9/11 but avoid taking similar forceful measures against foreign drug traffickers who enable the deaths of thousands of Americans each year by selling highly illegal and harmful narcotics? Oded Löwenheim argues that the answers to these questions lie in the social construction of agents of harm. "Predators and Parasites shows, with impressive scholarship, that world politics is characterized by a cartel-like structure that gives states monopolies of legitimate violence. Sovereignty and a global structure of authority are not mutually exclusive. In a sense, anarchy is in the eye of the beholder." —Robert O. Keohane, Princeton University "An invaluable contribution to the growing body of constructivist literature in international relations and should be read by anyone interested in the use of force in contemporary global politics . . . Goes a long way toward explaining America's War on Terror against al Qaeda and the Taliban and the widespread global support for this policy, as well as the highly negative global reaction to America's own intervention in Iraq and its norm-threatening doctrine of preemption." —Richard W. Mansbach, Iowa State University "Prepare to be boarded! Löwenheim delivers an essential constructivist tutorial on Great Power sovereignty and authority. An intellectual swashbuckler!" —Rodney Bruce Hall, Oxford University "Rejecting preventive war for moral consistency and just conduct, a fascinating discussion of pirates, terrorists, and revenge." —Jon Mercer, University of Washington Oded Löwenheim is Lecturer in the Department of International Relations at the Hebrew University of Jerusalem.

Their natural enemies largely determine the population size and dynamic behavior of many plant-eating insects. Any reduction in enemy number can result in an insect outbreak. Applied biological control is thus one strategy for restoring functional biodiversity in many agroecosystems. Predators and Parasitoids addresses the role of natural enemies i

Pollinators, parasites, purifiers, predators, decomposers – insects arguably play the most important roles in the functioning of the Earth’s ecosystems. This lavishly illustrated and highly authoritative book is structured around southern Africa’s 13 distinct biomes; it reflects the essential role insects play in most ecological processes such as pollination, predation, parasitism, soil modification and nutrient recycling; details how they serve as food for multitudes of other organisms, including bacteria and fungi, as well as specially adapted plants, insect-feeding arthropods, reptiles, birds and mammals; depicts the insects and phenomena described in some 2,000 photographs that accompany the accessible text; highlights the crucial role insects play as ecosystem service providers, giving intimate insight into the beauty and importance of insects in the natural world. Includes a guide to each of the 25 insect orders found in southern Africa, with images showing their diagnostic characters. This key publication detailing the latest research in the field of entomology will appeal to academics and nature enthusiasts alike.

A biologist shows the influence of wild species on our well-being and the world and how nature still clings to us—and always will. We evolved in a wilderness of parasites, mutualists, and pathogens, but we no longer see ourselves as being part of nature and the broader community of life. In the name of progress and clean living, we scrub much of nature off our bodies and try to remove whole kinds of life—parasites, bacteria, mutualists, and predators—to allow ourselves to live free of wild danger. Nature, in this new world, is the landscape outside, a kind of living painting that is pleasant to contemplate but nice to have escaped. The truth, though, according to biologist Rob Dunn, is that while "clean living" has benefited us in some ways, it has also made us sicker in others. We are trapped in bodies that evolved to deal with the dependable presence of hundreds of other species. As Dunn reveals, our modern disconnect from the web of life has resulted in unprecedented effects that immunologists, evolutionary biologists, psychologists, and other scientists are only beginning to understand. Diabetes, autism, allergies, many anxiety disorders, autoimmune diseases, and even tooth, jaw, and vision problems are increasingly plaguing bodies that have been removed from the ecological context in which they existed for millennia. In this eye-opening, thoroughly researched, and well-reasoned book, Dunn considers the crossroads at which we find ourselves. Through the stories of visionaries, Dunn argues that we can create a richer nature, one in which we choose to surround ourselves with species that benefit us, not just those that, despite us, survive.

Interactions between competitors, predators and their prey have traditionally been viewed as the foundation of community structure. Parasites – long ignored in community ecology – are now recognized as playing an important part in influencing species interactions and consequently affecting ecosystem function. Parasitism can interact with other ecological drivers, resulting in both detrimental and beneficial effects on biodiversity and ecosystem health. Species interactions involving parasites are also key to understanding many biological invasions and emerging infectious diseases. This book bridges the gap between community ecology and epidemiology to create a wide-ranging examination of how parasites and pathogens affect all aspects of ecological communities, enabling the new generation of ecologists to include parasites as a key consideration in their studies. This comprehensive guide to a newly emerging field is of relevance to academics, practitioners and graduates in biodiversity, conservation and population management, and animal and human health.
