Review title: Insights on underground ecology
Product review: David W. Wolfe's Tales From The Underground (0-7382-0128-6, ...) is a natural history of subterranean life, examining life beneath the earth's crust and exploring underground worlds and habitats ranging from those where bacteria flourish to that which houses insects and animals. Discussions of habitable zones blend with insights on underground ecology.
