Book Description
Past progress and future challenges R.J. Wheater Royal Zoological Society of Scotland, Edinburgh, UK. In the past two decades much has been achieved in the sphere of breeding endangered species, and we should be pleased that our co operative efforts have already borne so much fruit. However, on balance and despite the best efforts of conservationists, the position of wildlife in the wild places where they are best conserved has become worse, often dramatically worse. Before returning to the United Kingdom in 1972, I was in Uganda for 16 years, most of which time was spent as Chief Warden of Murchison Falls National Park. Our main problem was that an over-population of large mammals was having a devastating impact on the habitat. Devas tation was being wrought on woodland areas by the arrival of large numbers of elephants into the sanctuary of the Park, following changes in land use in the areas outside the Park. These changes were in response to the requirements of an ever-expanding human population.

Book Description
The case history approach has an impressive record of success in a variety of disciplines. Collections of case histories, casebooks, are now widely used in all sorts of specialties other than in their familiar appli cation to law and medicine. The case method had its formal beginning at Harvard in 1871 when Christopher Lagdell developed it as a means of teaching. It was so successful in teaching law that it was soon adopted in medical education, and the collection of cases provided the raw material for research on various diseases. Subsequently, the case history approach spread to such varied fields as business, psychology, management, and economics, and there are over 100 books in print that use this approach. The idea for a series of Casehooks in Earth Science grew from my experience in organizing and editing a collection of examples of one variety of sedimentary deposits. The prqject began as an effort to bring some order to a large number of descriptions of these deposits that were so varied in presentation and terminology that even specialists found them difficult to compare and analyze. Thus, from the beginning, it was evident that something more than a simple collection of papers was needed. Accordingly, the nearly fifty contributors worked together with George de Vries Klein and me to establish a standard format for presenting the case histories.

Book Description
This book brings together a set of approaches to the study of individual-species ecology based on the analysis of spatial variations of abundance. Distribution ecology assumes that ecological phenomena can be understood when analyzing the extrinsic (environmental) or intrinsic (physiological constraints, population mechanisms) that correlate with this spatial variation. Ecological processes depend on geographical scales, so their analysis requires following environmental heterogeneity. At small scales, the effects of biotic factors of ecosystems are strong, while at large scales, abiotic factors such as climate, govern ecological functioning. Responses of organisms also depend on scales: at small scales, adaptations dominate, i.e. the ability of organisms to respond adaptively using habitat decision rules that maximize their fitness; at large scales, limiting traits dominate, i.e., tolerance ranges to environmental conditions.​

Book Description
With more than 1,400 species, bats are an incredibly diverse and successful group of mammals that can serve as model systems for many unique evolutionary adaptations. Flight has allowed them to master the sky, while echolocation enables them to navigate in the dark. Being small, secretive, nocturnal creatures has made bats a challenge to study, but over the past 50 years, innovative research has made it possible to dispel some of the mystery and myth surrounding them to give us a better understanding of the role these animals play in the ecosystem. The structure of the book is based on several broad themes across the biological sciences, including the evolution of bats, their ecology and behavior, and conservation of biodiversity. Within these themes are more specific topics on important aspects of bat research, such as morphology, molecular biology, echolocation, taxonomy, systematics, threats to bats, social structure, reproduction, movements, and feeding strategies. Given its scope, the book will appeal to the wider scientific community, environmental organizations, and government policymakers who are interested in the interdisciplinary aspects of biology and nature.

'a true gem' —London Naturalist 'I love this book' —Nick Baker The author completes the book with an identification guide to dung itself, so that you can identify the animal that left it behind. Pellets or pats? Scats, spraints, frass, guano, spoor learn your way around different species droppings. There's also a dung-feeder s identification guide that includes the species you re most likely to encounter on an exploration of the dung heap. Journey through the digestive systems of humans, farm and wild animals, and meet some of nature’s ultimate recyclers as they eat, breed in and compete for dung. The fall of bodily waste onto the ground is the start of a race against the clock as a multitude of dung-feeders and scavengers consume this rich food source. From the enigmatic dung-rolling beetles to bat guano and giant elephant droppings, dung creates a miniature ecosystem to be explored by the aspiring dung watcher. The author completes the book with an identification guide to dung itself, so that you can identify the animal that left it behind. Pellets or pats? Scats, spraints, frass, guano, spoor – learn your way around different species’ droppings.
