The Eurasian beaver was near extinction at the start of the twentieth century, hunted across Europe for its fur, meat and castoreum. But now the beaver is on the brink of a comeback, with wild beaver populations, licensed and unlicensed, emerging all over Britain.As a keystone species, the beaver plays a vital role in the creation of sustainable wetland habitats through its damming activities, providing living opportunities for a broad spectrum of wildlife. Yet as proposals for reintroducing beavers are underway, re-establishing the beaver in Britain is still a controversial issue.This book presents a case for our future coexistence with beavers by providing factual information on this species that has now passed from national memory, covering the biology, behaviour and ecology of the Eurasian beaver in a British context, from their early history in archaeology and folklore to their contemporary field signs in the wild. This book familiarises readers once again, after almost 400 years of its absence, with the Eurasian beaver, providing essential information on its requirements in our human dominated landscape.This book is for those with a specific interest in beavers and their reintroduction, and for anyone with a general curiosity in natural history, ecology or animal behaviour. It can be used as a field guide to identify beaver field signs and observe beavers in the wild by wildlife surveyors or general land users, or as an introductory guide for anyone with an interest in beavers and how to recognise them.The authors have been actively involved in the study of beaver ecology, behaviour and reintroduction for many years. They have a first-hand knowledge of beavers in captivity and in the wild in both Britain and a range of other European countries.

Knowledge of bat echolocation and social calls, and identification using ultrasonic 'bat detectors' and sound analysis software, has grown significantly in the last decade. In this practical guide Jon Russ and contributors (Kate Barlow, Philip Briggs & Sandie Sowler) present the latest information in a clear and concise manner.The book covers topics including the properties of sound, how bats use sound, bat detectors and recording devices, analysis software, and call analysis. For each species found in the British Isles, information is given on distribution, emergence times, flight and foraging behaviour, habitat, echolocation calls including parameters for common measurements, and social calls. Calls are described in the context of the different technologies employed to record them (heterodyne, frequency division and time expansion). Various sonograms for each species are displayed in BatSound and AnaLookW. A species echolocation guide is included.

This book will allow ecologists to get started with the application of remote sensing and to understand its potential and limitations.

Bats are fascinating mammals about which we still have much to learn. As well as using ultrasonic echolocation calls for orientation and while foraging, they also have a complex array of vocalisations for communication. These are known as social calls and are an essential component of their colonial lifestyle.This book brings together the current state of knowledge of social calls relating to the bat species occurring within Britain and Ireland, with some additional examples from species represented elsewhere in Europe. It includes access to a downloadable library of calls to be used in conjunction with the book.Downloadable call librarySocial calls are complex and intriguing to listen to; they are after all produced with listeners in mind (other bats). To enjoy and fully appreciate social calls the reader must also have the opportunity to become a listener: each of the presented sonograms in the book is cross-referenced to downloadable 'time expanded' .wav sound files which are contained within a much wider library of calls for you to explore.Included in Social Calls of the Bats of Britain and IrelandThe authors start with an overview of the species of bats in Britain and Ireland (Chapter 1), and then introduce us to communication within the social world of bats (Chapter 2). Referencing the latest research, the authors explore how these calls can be classified according to their structure, and in many cases the context in which the calls are thought to be emitted (Chapter 3). Chapter 4 addresses aspects of survey methodology to be considered by those studying social calls. This leads on to the analysis of calls (Chapter 5), detailing the specific methods used and parameters commonly measured by researchers.The final, and main chapter (Chapter 6) introduces the 23 species covered in the book giving each a detailed profile including: habitat preferences, typical roosting locations, roost emergence times, mating strategies and maternity behaviour. Each species profile includes what is known about the social calls for that species and this text is supported by colour sonograms (created using Pettersson BatSound V4.1) of most of the calls discussed. Each sonogram is linked to a .wav sound file (Time Expansion x10) within the downloadable library. The sound files allow the reader to hear, as well as see, the calls produced using any bat sound analysis software that supports the .wav format.The authors conclude with a bibliography and an extensive list of references directly cross-referenced throughout the book.

Game fishes, particularly those of the salmon family, are critical indicators of the health of those ecosystems upon which we now know we are dependent. As the authors of this important environmental book argue, "e;Our game fishes [then] serve as more than merely an indicator of healthy waters. Instead, they can be regarded as iconic of the ecosystems in which they occur."e; Moreover, "e;the quality requirements of different types of fish population have formed the backbone of a great deal of water management in the UK, Europe and the USA over several decades."e;With sections on how and why Britain's game fishes are under pressure from changes in land use, agriculture, housing needs, etc. - and their concomitant pollution effects - this book assesses how our knowledge of these game fishes reflect the changing values we place on our surrounding wildlife.

New species of animal and plant are being discovered all the time. When this happens, the new species has to be given a scientific, Latin name in addition to any common, vernacular name. In either case the species may be named after a person, often the discoverer but sometimes an individual they wished to honour or perhaps were staying with at the time the discovery was made. Species names related to a person are 'eponyms'. Many scientific names are allusive, esoteric and even humorous, so an eponym dictionary is a valuable resource for anyone, amateur or professional, who wants to decipher the meaning and glimpse the history of a species name.Sometimes a name refers not to a person but to a fictional character or mythological figure. The Forest Stubfoot Toad Atelopus farci is named after the FARC, a Colombian guerrilla army who found refuge in the toad's habitat and thereby, it is claimed, protected it. Hoipollo's Bubble-nest Frog Pseudophilautus hoipolloi was named after the Greek for 'the many', but someone assumed the reference was to a Dr Hoipollo. Meanwhile, the man who has everything will never refuse an eponym: Sting's Treefrog Dendropsophus stingi is named after the rock musician, in honour of his 'commitment and efforts to save the rainforest'.Following the success of their Eponym Dictionary of Reptiles, the authors have joined forces to give amphibians a similar treatment. They have tracked down 1,609 honoured individuals and composed for each a brief, pithy biography. In some cases these are a reminder of the courage of scientists whose dedicated research in remote locations exposed them to disease and even violent death. The eponym ensures that their memory will survive, aided by reference works such as this highly readable dictionary. Altogether 2,668 amphibians are listed.

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 Galpagos, 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.
