Biospeleology: The Biology of Cavernicolous Animals discusses the fundamental concepts in understanding the biological make up of cave-dwelling animals. The title aims to relate the subterranean world as a habitat for organisms. The first part of the text tackles basic concerns, such as the concept of the subterranean world and cavernicoles, along with the history and research concerns in biospeleology. Next, the selection enumerates the subterranean flora and fauna, along with the geographical distribution and ecology of cavernicoles. The next two parts detail the physiology and behavior of cavernicoles, while the last part tackles the evolution of cavarnicoles. The book will be of great interest to zoologists, biologists, and ecologists who wish to gain a better understanding of the biological properties of subterranean organisms.
Despite their abundance in many parts of North America, salamanders have generally been neglected by all but a few specialists. In this book—first published in 1943—Sherman C. Bishop discusses in a lively but authoritative manner the 126 species and subspecies of salamanders that are known to exist in the United States, Canada, and Baja California. Group by group, Bishop describes salamanders in accounts that give the common and technical names, type of locality, range, habitat, size, anatomical characteristics, color, breeding habits, and relationships—all in a uniform arrangement that makes the handbook especially convenient for studying both living animals and laboratory specimens. His brief introduction surveys the relationships and general habits of salamanders and gives information on collecting and preserving them. In his foreword, Edmund D. Brodie, Jr., a specialist on salamanders, updates the taxonomy of the group.
