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?

Subterranean Rodents presents achievements from recent years of research on these rodents, divided into five sections: ecophysiology; sensory ecology; life histories, behavioural ecology and demography; environmental and economical impact; molecular ecology and evolution. It is a must for all researchers working in this field and will be of interest to zoologists, physiologists, morphologists, ecologists, and evolutionary biologists.

Subterranean life exists within an extraordinary environment and has evolved among different groups of mammals all over the globe. With relatively constant temperature, few opportunities to meet organisms other than the immediate family, and a completely different sensory environment, the evolution of such life is fascinating. Locomotion, communication, food-finding, navigation, circadian rhythms, and indeed the whole of the animals' physiology may be specialized to cope with life underground. And from burrowing to blindness, magnetic communication to the weird bee-like eusociality of blind mole rats, specialization has been extreme and has led to speciation in a whole range of new contexts. That the subterranean way of life occurs in different species of mammals across the globe has provided scientists with one of nature's best studied global evolutionary demonstrations of adaptive radiation and speciation. The revolution in molecular biology that has occurred over the last ten years has massively expanded these horizons, allowing scientists to explore, map, and clone the genes underlying the basis of adaptation and speciation and translate their fascinating structural and functional evolution into genes and genomic language. This book draws together the burgeoning literature about all aspects of the biology of subterranean mammals. Beginning with their evolutionary history and the processes that led to the subterranean way of life, the author reviews ecology, behavior, and physiology within the context of the highly stressful subterranean context, considers the specialization that has evolved in response, and then compares the eleven families of extant subterranean mammals. The incredible circumstances surrounding subterranean mammals present a unique, global, 'natural experiment' in evolution that has implications throughout biology. As such, this broad survey will stand as an invaluable reference to evolutionary biologists, ecologists, and molecular biologists for years to come.

This volume, first published in 2000, explores the range of social systems in this fascinating group to understand how complex social systems evolved.

This volume brings together more than a decade of information collected in the field and lab on the naked mole-rat (Heterocephalus glaber), a northeast African mammal unique for its physical characteristics and eusociality. Nearly blind and virtually hairless, naked mole-rats inhabit large subterranean colonies in which only one female and her one to three mates conceive offspring, while the young from previous litters maintain and defend the group as do workers in colonies of the social insects. In this first major treatise on naked mole-rats an international group of researchers covers such topics as the evolution of eusociality, phylogeny and systematics of the rodent family Bathyergidae, population and behavioral ecology and genetics of naked mole-rats in the field, vocal and nonvocal behaviors, social organization and divisions of labor within colonies, and climatic, social, and physiological factors affecting growth, reproduction, and reproductive suppression.

Lacey, C. E. Liddell, E. McDaid, K. Nelson, K. M. Noonan, J. O'Riain, J. W. Pepper, H. K. Reeve, and D. A. Schlitter. Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This volume focuses on the huge advances in the last 25 years on the use of this animal model for biomedical research (cancer, heart disease and neurodegeneration), fundamental neuroscience and basic subterranean biology. In 2013, Science magazine named the naked mole-rat as the Vertebrate of the Year. This was partly due to research carried out documenting its extreme longevity, negligible senescence, and prolonged maintenance of cancer free, good health well into old age as well as seminal work on mechanisms involved in these processes, pain and hypoxia resistance. In addition to this research focus on longevity and chronic diseases such as cancer and cardiovascular disease, the naked mole-rat has also made a substantial contribution to the fields of ecophysiology, neuroscience and behavior. With international contributions, this book provides a valuable text for zoological students, behavioral scientists and biomedical researchers.

Humans have "gone underground" for survival for thousands of years, from underground cities in Turkey to Cold War-era bunkers. But our burrowing roots go back to the very beginnings of animal life on Earth. Many animal lineages alive now—including our own—only survived a cataclysmic meteorite strike 65 million years ago because they went underground.On a grander scale, the chemistry of the planet itself had already been transformed many millions of years earlier by the first animal burrows which altered whole ecosystems. Every day we walk on an earth filled with an underground wilderness teeming with life. Most of this life stays hidden, yet these animals and their subterranean homes are ubiquitous, ranging from the deep sea to mountains, from the equator to the poles. Burrows are a refuge from predators, a safe home for raising young, or a tool to ambush prey. Burrows also protect animals against all types of natural disasters. Filled with spectacularly diverse fauna, acclaimed paleontologist and ichnologist Anthony Martin reveals this fascinating, hidden world that will continue to influence and transform life on this planet.

The first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.

Mason had decided that the rats had to go… they had other plans… (note: very short story!)

When eleven-year-old Gregor falls through a grate in the laundry room of his apartment building, he hurtles into the dark Underland, where spiders, rats and giant cockroaches coexist uneasily with humans. This world is on the brink of war, and Gregor's arrival is no accident. Gregor has a vital role to play in the Underland's uncertain future.
