Zebra Stripes

From eminent biologists like Alfred Russel Wallace and Charles Darwin to famous authors such as Rudyard Kipling in his Just So Stories, many people have asked, “Why do zebras have stripes?” There are many explanations, but until now hardly any have been seriously addressed or even tested. In Zebra Stripes, Tim Caro takes readers through a decade of painstaking fieldwork examining the significance of black-and-white striping and, after systematically dismissing every hypothesis for these markings with new data, he arrives at a surprising conclusion: zebra markings are nature’s defense against biting fly annoyance. Popular explanations for stripes range from camouflage to confusion of pr...

Antipredator Defenses in Birds and Mammals

Tim Caro explores the many & varied ways in which prey species have evolved defensive characteristics and behaviour to confuse, outperform or outwit their predators, from the camoflaged coat of the giraffe to the extraordinary way in which South American sealions ward off the attacks of killer whales.

Cheetahs of the Serengeti Plains

Cheetahs of the Serengeti Plains is the most comprehensive account of carnivore social behavior to date. Synthesizing more than a decade of research in the wild, this book offers a detailed account of the behavior and ecology of cheetahs. Compared with other large cats, and other mammals, cheetahs have an unusual breeding system; whereas lions live in prides and tigers are solitary, some cheetahs live in groups while others live by themselves. Tim Caro explores group and solitary living among cheetahs and discovers that the causes of social behavior vary dramatically, even within a single species. Why do cheetah cubs stay with their mother for a full year after weaning? Why do adolescents re...

Conservation by Proxy

  • Publisher: Island Press

The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utili...

Behavioral Ecology and Conservation Biology

In just the last few years, behavioral ecologists have begun to address issues in conservation biology. This volume is the first attempt to link these disciplines formally. Here leading researchers explore current topics in conservation biology and discuss how behavioral ecology can contribute to a greater understanding of conservation problems and conservation intervention programs. In each chapter, the authors identify a conservation issue, review the ways it has been addressed, review behavioral ecological data related to it, including their own, evaluate the strengths and weaknesses of the behavioral ecological approach, and put forward specific conservation recommendations. The chapters...

Sensory Ecology, Behaviour, and Evolution

This is the first modern textbook of sensory ecology in two decades, one of the most popular and rapidly growing subjects in biology. The topic deals with how animals capture (and send) information from their environment, and the sensory systems involved. It investigates the type of information that is gathered by animals, how it is used in a range of behaviours, and the evolution of such traits. Sensory ecology deals with both mechanistic questions (e.g. howsensory receptors capture information from the environment, and how the physical attributes of the environment affect information transmission) and functional questions (e.g. the adaptive significance ofthe information used by the animal...

Concealing Coloration in Animals

Color can attract mates, intimidate enemies, and distract predators. But it can also conceal animals from detection. It is an adaptation to the visual features of the environment but also to the perceptual and cognitive capabilities of other organisms. Judy Diamond and Alan Bond reveal factors at work in the evolution of concealing coloration.

  • Publisher: Island Press

Prairie dogs and the grassland habitat in which they play a key ecological role have declined precipitously over the past two centuries. The current number of prairie dogs is believed to be less than 2 percent of the number encountered by Lewis and Clark in the early 1800s, and only a fraction of grassland ecosystem remains. Conservation of the Black-Tailed Prairie Dog offers specific information to help scientists and managers develop rigorous plans for ensuring the long-term survival of the prairie dog and its habitat. With contributions from thirty leading biologists who are actively working to save prairie dogs, the book addresses a range of pivotal issues including: the ecology and soci...
