"Marmot Biology Sociality, Individual Fitness and Population Dynamics"--

In this book, based on over twenty years of study around the world, the author summarizes and synthesizes virtually everything that is known of the social behaviour and ecology of marmots. The organizing principle of the author's approach is evolution by natural selection - and thus, the degree to which the social behaviour of free-living animals can be interpreted as representing adaptations to particular environmental conditions. This book is essentially a single, widespread genus (genus Marmota comprising fourteen species found in North America and Eurasia. As such, it represents a productive union of theoretical insights from Darwinism and modern sociobiology, accompanied by a wealth of empirical data. Marmots are notable in that they constitute a relatively homogeneous group, made up of numerous species which greatly resemble each other. However, they occupy widely varying habitats - from temperate, lowland elevations to (more often) alpine meadows - and theory would predict behavioural adaptations to match their habitats.

An Open Letters Review Best Book of the Year A leading expert in animal behavior takes us into the wild to better understand and manage our fears. Fear, honed by millions of years of natural selection, kept our ancestors alive. Whether by slithering away, curling up in a ball, or standing still in the presence of a predator, humans and other animals have evolved complex behaviors in order to survive the hazards the world presents. But, despite our evolutionary endurance, we still have much to learn about how to manage our response to danger. For more than thirty years, Daniel Blumstein has been studying animals’ fear responses. His observations lead to a firm conclusion: fear preserves security, but at great cost. A foraging flock of birds expends valuable energy by quickly taking flight when a raptor appears. And though the birds might successfully escape, they leave their food source behind. Giant clams protect their valuable tissue by retracting their mantles and closing their shells when a shadow passes overhead, but then they are unable to photosynthesize, losing the capacity to grow. Among humans, fear is often an understandable and justifiable response to sources of threat, but it can exact a high toll on health and productivity. Delving into the evolutionary origins and ecological contexts of fear across species, The Nature of Fear considers what we can learn from our fellow animals—from successes and failures. By observing how animals leverage alarm to their advantage, we can develop new strategies for facing risks without panic.

Focusing on the physiological and behavioral factors that enable a species to live in a harsh seasonal environment, this book places the social biology of marmots in an environmental context. It draws on the results of a forty-year empirical study of the population biology of the yellow-bellied marmot near the Rocky Mountain Biological Laboratory in the Upper East River Valley in Colorado, USA. The text examines life-history features such as body-size, habitat use, environmental physiology, social dynamics, and kinship. Considerable new data analyses are integrated with material published over a fifty-year period, including extensive natural history observations, providing an essential foundation for integrating social and population processes. Finally, the results of research into the yellow-bellied marmot are related to major ecological and evolutionary theories, especially inclusive fitness and population regulation, making this a valuable resource for students and researchers in animal behavior, behavioral ecology, evolutionary biology, ecology and conservation.
