Wild Otters answers the need for an up-to-date, scientifically-oriented introduction to the Lutra lutra species. Based in part on the author's extensive field observations, the book provides a superb basis for active conservation management of a species faced with an increasingly hostile environment. Topics include social organization and behavior, food and foraging strategies, ecological information on their main prey fish, problems of energetics and thermo-insulation, population structure, mortality and reproduction, and the impact of humans. Packed with illustrations and photographs, Wild Otters is perfect for students and researchers in ecology, conservation, zoology, and animal behavior.

Carnivores include some of the most impressive, dangerous and mysterious animals in the world. Hans Kruuk has spent his life studying them against magnificent backdrops, from the Serengeti savannahs and Kalahari deserts to the Scottish Highlands, from the Galapagos Islands to the Far East. In each location he has used meticulous observation of animal behaviour to understand the ecology and natural history of wild carnivore populations, and ultimately to promote their conservation. This book describes the methods, challenges and rewards of the science of behavioural ecology. However, it essentially concerns the personal, rather than the scientific, side of that work, and above all the field experiences involved. With photographs and line drawings, it brings to life African safaris, the hyena in his bath, flights with vultures, dives with otters, attacks by a badger in Scotland and by feral dogs in Galapagos, gull-eating hedgehogs in Britain and the role of animals in African witchcraft. The author communicates his lifelong fascination with wildlife through these unique experiences and the insights they afforded him. Professor Kruuk is a leading authority on animal behaviour and the author of classic studies of hyaenas, otters and badgers, as well as a biography of his Oxford mentor Niko Tinbergen.

Hans Kruuk, a life-long naturalist, tells the fascinating story of carnivores and humans' intricate relationships with them. The book is illustrated with specially commissioned drawings, and deals not only with the wild beauty of carnivores and their conservation, but also with the topics of furs and medicine, man-eaters and sheep-killers. Kruuk explains in simple terms the role of carnivores in nature, how they impact human life, art and literature, and how we instinctively respond to them and why.

A charismatic naturalist, bird-watcher, teacher, artist, photographer, film-maker, and winner of the Nobel Prize, Niko Tinbergen was a prominent and influential scientist. Jointly with Konrad Lorenz, he laid the foundation for a new science, the biological study of animal behaviour. 'Ethology', and his talent for devising behaviour-testing experiments, provided an outlet for Niko's enthusiasm for gulls and sticklebacks, snow-buntings and foxes, wasps and falcons, and even children. This first full-length biography of Niko Tinbergen, lavishly illustrated with many of Niko's own drawings, describes his background in Holland, a naturalists' paradise, and the beginnings of his investigations into the behaviour of birds, fish, and insects. Hans Kruuk also explores is Niko's relationship with his colleague and co-Nobelist Konrad Lorenz. These were two men full of contrasts: Niko a charming, self-effacing field man and experimenter; Konrad a flamboyant and egocentric German, always full of new ideas. Niko's Nature goes on to follow Niko's progress in Oxford after the Second World War, where he became the world authority on the behaviour of animals in the wild: his inspiring book The Study of Instinct remains an all-time classic. As a scientist Niko will always be known for the four fundamentally different ways in which he asked the question 'why does an animal do this?' These questions, about physiology, development, evolution, and function, became known as 'Tinbergen's four whys'. But Niko's successes came at a price - severe and devastating depressions that were to plague him throughout his career. In this fascinating and engaging story, Niko's long-time friend and student Hans Kruuk argues that his impact as a scientist and naturalist was in large part due to his skills as a communicator, photographer, and film-maker. Niko's Nature is an intimate and insightful portrait of an extraordinary figure.

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 emphasizes 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.
