Many mammals like to dig in the dirt, but few call it home. Those that do, such as mole-rats, zokors, and tuco-tucos, have developed novel adaptations to their subterranean life, including bones and muscles modified for efficient digging and ways to "see" underground without using their eyes. These unusual traits, adopted independently by unrelated groups around the world, also make subterranean rodents fascinating subjects for biologists. Life Underground provides the first comprehensive review of the biology of subterranean rodents. Arranged by topic rather than by taxon to facilitate cross-species comparisons, chapters cover such subjects as morphology, physiology, social behavior, genetic variation, and evolutionary diversification. Two main questions run throughout the book. First, to what extent has subterranean life shaped the biology of these animals, leading to similar adaptations among otherwise dissimilar species? Second, how have the distinct evolutionary histories of these groups led to different solutions to the challenges posed by life underground?

There are over one billion organisms in a pinch of soil, yet we know much more about deep space than about the universe below. In Tales from the Underground, Cornell ecologist David Wolfe takes us on a tour through current scientific knowledge of the subterranean world. We follow the progress of discovery from Charles Darwin's experiments with earthworms, to Lewis and Clark's first encounter with prairie dogs, to the use of new genetic tools that are revealing an astonishingly rich ecosystem beneath our feet. Wolfe plunges us deep into the earth's rocky crust, where life may have begun-a world devoid of oxygen and light but safe from asteroid bombardment. Primitive microbes found there are turning our notion of the evolutionary tree of life on its head: amazingly, they represent perhaps a full third of earth's genetic diversity. As Wolfe explains, creatures of the soil can work for us, by providing important pharmaceuticals and recycling the essential elements of life, or against us, by spreading disease and contributing to global climate change. The future of our species may well depend on how we manage our living soil resources. Tales from the Underground will forever alter our appreciation of the natural world around-and beneath-us.

Describes what it was like for slaves escaping to freedom, how slaves received help from people on the way, and how they found out about the trails to the North.

This is the first comprehensive survey of troglodytes and other cave dwellers throughout the world from Neanderthal Man to the present day. Mr. Kempe, of the British Museum of Natural History, examines why people have chosen to live in caves or natural shelters, the nature of life and the distinctive characteristics of the dwellings, and skillfully weaves these strands into a fascinating history of man's underground life.

A woman's lover from her youth resurfaces in her adult life, and she is drawn into the turmoil surrounding disturbing accusations about his Nazi past. From pre WWI Dresden, Germany to contemporary urban Toronto, the dual point of view narrative crosses continents and moves through time as it explores the ambiguity of human emotion, how our natures can embody both the ideals and delights of love alongside the most base and dispassionate sensibilities.
