Cave organisms are the ‘monsters’ of the underground world and studying them invariably raises interesting questions about the ways evolution has equipped them to survive in permanent darkness and low-energy environments. Undertaking ecological studies in caves and other subterranean habitats is not only challenging because they are difficult to access, but also because the domain is so different from what we know from the surface, with no plants at the base of food chains and with a nearly constant microclimate year-round. The research presented here answers key questions such as how a constant environment can produce the enormous biodiversity seen below ground, what adaptations and peculiarities allow subterranean organisms to thrive, and how they are affected by the constraints of their environment. This book is divided into six main parts, which address: the habitats of cave animals; their complex diversity; the environmental factors that support that diversity; individual case studies of cave ecosystems; and of the conservation challenges they face; all of which culminate in proposals for future research directions. Given its breadth of coverage, it offers an essential reference guide for graduate students and established researchers alike.
"This booklet is part of a national and international program whose goal is to promote resposible use of wild lands by recreationists;" it "describes techniques you can use to reduce the evidence of your visit and minimize disturbance to the local ecology." Covers five basic principles of cave conservation and minimum-impact caving techniques, in order to protect cave features, artifacts, and inhabitants, and to prevent the need for rescuing spelunkers.
A comprehensive guide to navigating rock and mineral formations safely.
This book reveals the science and beauty of Mammoth Cave, the world's longest cave, which has played an important role in the natural sciences. It offers a comprehensive and interdisciplinary treatment of the cave, combining insights from leading experts in fields ranging from archeology and cultural history to life science and geosciences. The first animals specialized for cave life in North America, including beetles, spiders, crayfish, and fish, were discovered in Mammoth Cave in the 1840s. It has also been used and explored by humans, including Native Americans, who mined its sulfate minerals and later African-American slaves, who made a map of the cave. More recent stories include 'wars' between commercial cave owners, epic exploration trips by modern cave explorers, and of course tourism. The first section of the book is an extensive description including maps and photos of the cave, its basic structural pattern, and how it relates to the surface landscape. The second section covers the human history of utilization and exploration of the cave, including mining, tourism, and medical experiments. Cave science is the topic of the third section, including geology, hydrology, mineralogy, climatology, paleontology, ecology, biodiversity, and microbiology. The fourth section looks to the future, with an overview of environmental issues facing Mammoth Cave managers. The book is intended for anyone interested in caves in general and Mammoth Cave in particular, experts in one discipline seeking information about other areas, and researchers and students interested in the many avenues of pursuit possible in Mammoth Cave.
This textbook presents a comprehensive overview of the environmental impacts of various types of outdoor recreation, and how these can be best managed. As a field of study, recreational ecology is both multidisciplinary and interdisciplinary, and the authors seek to develop a deeper understanding of both the role and function of the factors that influence visitor numbers and their impact. An accessible and comprehensive textbook, it features numerous types of outdoor recreational activities including hill walking, rock climbing, mountain marathons, skiing, scuba diving and more. Drawn from several global case studies, the authors estimate the current and future numbers involved in outdoor recreation, and how best these numbers can be managed. Effective visitor impact management actions arise from collaboration between recreation ecologists, social scientists, experienced recreation managers, recreation stakeholders and the recreationalists themselves: as such, this book will be multi-disciplinary in scope. This practical and engaging textbook will be invaluable to students and scholars of outdoor recreation and adventure tourism as well as practitioners and managers working in the field.
Cave and karst landforms are distributed widely around the world. They have many values and are an integral component of the world's biodiversity. Some are habitats for a wide range of endemic species of flora and fauna, while others house rare and endangered species. Still others are the sources of rare minerals and some are important for resources such as groundwater, while some are venerated as sites of religious, spiritual and cultural importance. Many such landforms encompass one or many of these values. As special places, cave and karst landforms require special management. This small booklet has been prepared as a brief guide for planners, managers and users of cave and karst estates and provides general information and practical guidelines for the management of cave and karst ecosystems.
