Book Description
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.

Book Description
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.

Book Description
'Punchily written ... He leaves the reader with a sense of the gross injustice of a world where health outcomes are so unevenly distributed' Times Literary Supplement 'Splendid and necessary' Henry Marsh, author of Do No Harm, New Statesman There are dramatic differences in health between countries and within countries. But this is not a simple matter of rich and poor. A poor man in Glasgow is rich compared to the average Indian, but the Glaswegian's life expectancy is 8 years shorter. The Indian is dying of infectious disease linked to his poverty; the Glaswegian of violent death, suicide, heart disease linked to a rich country's version of disadvantage. In all countries, people at relative social disadvantage suffer health disadvantage, dramatically so. Within countries, the higher the social status of individuals the better is their health. These health inequalities defy usual explanations. Conventional approaches to improving health have emphasised access to technical solutions – improved medical care, sanitation, and control of disease vectors; or behaviours – smoking, drinking – obesity, linked to diabetes, heart disease and cancer. These approaches only go so far. Creating the conditions for people to lead flourishing lives, and thus empowering individuals and communities, is key to reduction of health inequalities. In addition to the scale of material success, your position in the social hierarchy also directly affects your health, the higher you are on the social scale, the longer you will live and the better your health will be. As people change rank, so their health risk changes. What makes these health inequalities unjust is that evidence from round the world shows we know what to do to make them smaller. This new evidence is compelling. It has the potential to change radically the way we think about health, and indeed society.

Book Description
Poorer people live shorter lives and suffer higher levels of ill health than the more affluent in society, and this disparity highlights the sensitivity of human health to socio-economic factors. This booklet examines this social gradient in health and explains how psychological and social influences affect physical health and longevity. It also considers the role of public policy in promoting a social environment that is more conducive to better health. Topics discussed include: stress, early childhood health, social exclusion, work, unemployment and job insecurity, social support networks, the effects of alcohol and other drug addictions, food and nutrition, and healthier transport systems.
