Provides a guided tour of predator-prey relationships through the very different but often overlapping worlds of mammals, birds, fish, reptiles, plants, insects, and microorganisms, as well as the fossilized record of the dinosaurs. We learn, in every instance, not only the intricacies of interdependence in the vast chain of being but also the astonishing adaptability that is inherent in nature, whether the drama be played out on the African plains, in the depths of the ocean, or in the familiar confines of our own backyard. The author is Curator of Vertebrate Paleontology at the Royal Ontario Museum in Toronto and professor of zoology at the University of Toronto. Illustrated.

Are our lives meaningless? Is death bad? Would immortality be better? Alternatively, should we hasten our deaths by acts of suicide? Many people are tempted to offer comforting optimistic answers to these big questions. The Human Predicament offers a less sanguine assessment, and defends a substantial, but not unmitigated, pessimism.

Providing both a theoretical background and practical examples of natural resource conflict, this volume explores the pressures on natural resources leading to scarcity and conflict. It is shown that the causes and driving forces behind natural resource conflicts are diverse, complex and often interlinked, including global economic growth, exploding consumption, poor governance, poverty, unequal access to resources and power. The different interpretations of nature-culture and the role of humans in the ecosystem are often at the centre of the conflict. Natural resource conflicts range from armed conflicts to conflicts of interest between stakeholders in the North as well as in the South. The varying driving forces behind such disputes at different levels and scales are critically analysed, and approaches to facilitate and enforce mediation, transformation and collaboration at these levels and scales are presented and discussed. In order to transform existing resource conflicts, as well as to decrease the risk of future conflicts, approaches that enhance and enforce collaboration for sustainable development at global, regional, national and local levels are reviewed, and sustainable pathways suggested. A range of global examples is presented including water resources, fisheries, forests, human–wildlife conflicts, urban environments and the consequences of climate change. It will be a valuable text for advanced students of natural resource management, environment and development studies and peace and conflict management. The book will also be of interest to practitioners in the field of natural resource management.

Chapter 1 Temperature Regulation in Animals There are, broadly speaking, two kinds of animals with regard to body temperature: exothermic (cold-blooded) and endothermic (warm-blooded) animals. The exothermic animals, such as reptiles, do not supply body heat by metabolic conversion of food to heat. Reptiles allow their surroundings to determine their body temperature. They lie out in the sun to warm their body. If they are too hot, they seek the shade or even burrow into the ground. At night they hide from the cold in burrows or squeeze into cracks between rocks or hide in leaf cover. Reptiles avoid the extremes of temperature. When reptiles become cool, their movements slow down, and chemical processes in their bodies, such as digestion, are inhibited. Predators, such as hawks and eagles, find it easier to prey on lizards and snakes in cooler weather. The distribution of reptiles is somewhat limited by their exothermic character. They do not thrive in cold climates1. What are the advantages and disadvantages in being exothermic? When the lizard is in a cool environment and cannot find a warmer spot, its body simply cools to the temperature of the surroundings. It is not necessary for the exothermic lizard to generate heat to increase its body temperature. This means that the lizard uses less energy and does not have to eat as much. As the lizard cools its digestion, breathing rate and heart rate slow, saving energy. A disadvantage occurs when the cool lizard is attacked by a predator. If warm, he could run fast and have a much better chance of 1 St. Patrick did not chase the snakes out of Ireland. Ireland was already completely free of snakes. St. Patrick was instrumental in converting pagans to Christianity. Since the snake was a symbol used in pagan rituals, St. Patrick was influential in ridding Ireland of the ritual use of symbolic snakes. 10 Verne A. Simon evading capture. A warm lizard being chased by a predator can move quite fast for a short distance, but like other exotherms, lacks endurance and soon tires. When the exotherm is running fast, its effort is anaerobic, that is, is not using oxygen, and lactic acid is building up in its body. It soon tires and is unable to exert itself. It must recover by taking in oxygen to rid the body of lactic acid. Another disadvantage of exothermic life is that cold climates are not available as habitat. If there is a sudden climate change, an exothermic animal wouldn't be able to mount the sustained effort needed to migrate to a better environment. The exothermic creature might simply perish. About 180 million years ago, mammals appeared. Mammals are endothermic (warm-blooded) and are able to maintain a nearly constant body temperature regardless of the temperature of their surroundings within wide limits. Their bodies will not tolerate too high or too low a temperature. If the surroundings are too hot or cold, causing the body temperature to exceed allowed limits, the animal will die. Mammals have furry coats to help them tolerate low temperatures. Sea-dwelling mammals-whales, seals, and walrus-have thick layers of blubber for insulation. Birds are endothermic and have feathers to protect them from the cold. Many types of birds and mammals survive in cold climates. Emperor penguins even live in the Antarctic, in the coldest climate on earth. Under normal circumstances, mammals and birds manage to keep this very nearly constant body temperature regardless of the temperature of their surroundings. Mammals are characterized by having body hair and suckling their young. This latter behavior gives the class its name; mammals must have mammary glands. A second advantage is that endothermic animals are not limited to activity only in daylight hours. In many locat

Orcas (or killer whales) are one of the planet's supreme predators. Alongside humans, they have the most complex brains to be found in nature. But while one of these two species has killed 200 million members of its own kind in the twentieth century alone, the other has killed none. This is where Jeffrey Masson's fascinating new book begins: there is something different about humans. Masson has shown us that animals can teach us much about our own emotions - about love (dogs), contentment (cats) and grief (elephants). But they have much to teach us about the negative emotions such as anger and aggression as well, and in unexpected ways. In Beasts he demonstrates that the violence we perceive in the 'wild' is mostly a matter of projection. We link the basest human behaviour to animals, to 'beasts', and claim the high ground for our species. We are least 'human', we think, when we succumb to our primitive, animal instincts. In fact, nothing could be further from the truth. Animal predators kill to survive, but there is nothing in the annals of animal aggression remotely equivalent to the violence mankind has inflicted upon itself. Humans, and humans in our modern industrialised world in particular, are the most violent species in existence. We lack what all other animals have: a check on aggression that serves the species rather than destroys it. And it is here that animals have something vitally important to teach us about ourselves.

Big cats such as lions, tigers, leopards, and jaguars fascinate us like few other creatures. They are enduring symbols of natural majesty and power. Yet despite the magnetic appeal of the big cats, their origins and evolutionary history remain poorly understood—and human activity threatens to put an end to the big cats’ glory. On the Prowl is a fully illustrated and approachable guide to the evolution of the big cats and what it portends for their conservation today. Mark Hallett and John M. Harris trace the origins of these iconic carnivores, venturing down the evolutionary pathways that produced the diversity of big cat species that have walked the earth. They place the evolution and paleobiology of these species in the context of ancient ecosystems and climates, explaining what made big cats such efficient predators and analyzing their competition with other animals. Hallett and Harris pay close attention to human impact, from the evidence of cave paintings and analysis of ancient extinctions up to present-day crises. Their engaging and carefully documented account is brought to life through Hallett’s detailed, vivid illustrations, based on the most recent research by leading paleontologists. Offering a fresh look at the rise of these majestic animals, On the Prowl also makes a powerful case for renewed efforts to protect big cats and their habitats before it is too late.
