Описание: 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. Without burrowing, the planet would be very different today. 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 under-ground 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: fires, droughts, storms, meteorites, global warmings--and coolings. In a book 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.

Описание: Provides an accessible introduction to cave and subterranean biology and covers a range of biological processes including ecosystem function, evolution and adaptation, community ecology, biogeography, and conservation.
Описание: The focus of this book is on the more than 2000 caves of the Greenbrier Valley of West Virginia of which the 14 with lengths greater than 10 km have an aggregate length of 639 km. The major caves form the core part of sub-basins which drain to big springs and ultimately to the Greenbrier River. Individual chapters of this book describe each of the major caves and its associated drainage basin. The caves are formed in the Mississippian Greenbrier Limestone in a setting of undulating gentle folds. Fractures, lineaments and confining layers within the limestone are the main controlling factors. The caves underlie an extensive sinkhole plain which may relate to a major erosion surface. The caves are habitat for both aquatic and terrestrial organisms which are cataloged and described as are the paleontological remains found in some of the caves. The sinkhole plain of the Greenbrier karst and the underlying complex of cave systems are the end result of at least a ten million year history of landscape evolution which can be traced through the evolving sequence of cave passages and which is described in this book.
