Book Description
Once widespread throughout Great Britain, the otter suffered a severe decline in numbers and distribution in the 1950s. Otter populations are now recovering very gradually and it is possible to assist this recovery by ensuring the habitats favoured by otters and other wildlife are more widespread along rivers. This handbook provides a brief summary of the natural history and current status of otters, an overview of the past decline of otter populations, a brief description of preferred habitats and more detailed practical suggestions for river management to encourage otters back to old haunts.

Book Description
This book focuses on the European otter, describing its life history, including fresh information and providing details of survey methods and the state of populations throughout the range. Otters have decreased substantially in numbers and range during the present century through a combination of pollution, habitat destruction and direct persecution. The otter, at the top of the food chain, is a vulnerable animal in a vulnerable environment - the river - and can be seen as an indicator of a healthy environment; a good otter population indicates a properly functioning river ecosystem. The research of the authors highlights the fact that successful conservation of this familiar though elusive animal depends upon public education and sympathy as much as upon detailed ecological knowledge. This account will appeal to amateur naturalists, teachers of natural history and biological sciences and students of animal ecology and conservation. It also provides an important reference for professional conservationists and wildlife biologists.

Book Description
These booklets give the general reader facts and information about fur-bearing mammals from a more conservation-oriented perspective than information generally available from other sources. Each is based on the relevant SSC Action Plan, and is well-illustrated with color photographs and a center spread of sketches showing the animals in action.

Book Description
Social behavior and habitat selection of river otters (Lontra canadensis) are highly variable among populations and there is limited information on how space use of this mustelid changes in human-modified environments. Understanding the spatial ecology of river otters is important for efforts focused on habitat management and preventing human-wildlife conflicts. My objectives were to quantify: (1) home ranges and core areas, (2) second- and third-order habitat selection, and (3) relationships between home-range size and intensity of human development for river otters in southern Illinois. VHF transmitters were used to track river otters during 2014-2016. Home-range and core-area sizes then were compared between males (n = 8) and females (n = 10), as was home-range overlap. I also compared the frequency individuals were located

Book Description
Otters are highly charismatic and popular animals of very considerable concern to conservationists worldwide. Written by the pre-eminent authority in the field, this book builds on the reputation of the author's landmark monograph of the European otter, Wild Otters (OUP, 1995). Furthermore, its broader scope to include all species of otter in North America as well as Europe and elsewhere leads to a deeper synthesis that greatly expands the book's overall relevance and potential readership. Aimed at naturalists, scientists and conservationists, its personal style and generously illustrated text will appeal to amateurs and professionals alike. It emphasises recent research and conservation management initiatives for all 13 species of otter worldwide, incorporates recent molecular research on taxonomy and population genetics, and discusses the wider implications of otter studies for ecology and conservation biology. As well as enchanting direct observations of the animals, there is guidance about how and where to watch and study them. From otters in the British and American lakes and rivers, to sea otters in the Pacific Ocean, giant otters in the Amazon and other species in Africa and Asia, this book provides an engaging approach to their fascinating existence, to the science needed to understand it, and to the very real threats to their survival.
