This ground-breaking volume covers 42 species of terrestrial mammal – from the red deer to the pygmy shrew, from the pine marten to the hedgehog. The subject is introduced for the first time as a single overarching field of study, including guidance on survey methods, analysis of sound recordings and appropriate software. The book covers species in Britain, Ireland, the Isle of Man and the Channel Islands. Containing over 300 figures in total, each species is considered in detail, with specific spectrogram examples. Furthermore, the book allows the reader access to a downloadable sound library containing more than 250 recordings. The authors have extensive experience and expertise in bioacoustics, including in the sound identification of mammals. They are also heavily involved in creating tools that use machine-learning algorithms to recognise mammal species from their calls. A real ear-opener, this will be the essential handbook for many years to come, serving ecological consultants, academics, conservationists, hobbyists and serious mammal recorders alike.

Based on more than 1.8 million records, this Atlas provides the most up-to-date information on the current distributions of both terrestrial and marine mammals in the United Kingdom, the Channel Islands and the Isle of Man. Many changes over time, such as the rapid invasion of the grey squirrel, the recovery of the pine marten and the decline of the water vole, are readily apparent from the detailed maps. Fully illustrated with photographs, detailed information is provided for 84 species, including descriptions of their ecology and identification, together with graphs showing the seasonal distribution of records. Data are also presented for feral species, vagrants, and cetaceans that have only ever been found as strandings. The Atlas will be an invaluable source of information to mammal enthusiasts, professional ecologists, and policy makers.
Bat detector surveys are carried out by ecological consultants, researchers, conservationists and hobbyists. Understanding and categorising non-bat sounds in surveys offers the potential of knock-on benefits for informing development projects (e.g. other important records discovered within a site), as well as the possibility of associated conservation benefits. In recent years the number of people carrying out these surveys and recording calls with bat detectors has grown considerably. These surveys often generate vast amounts of audio recordings, resulting in the heavy workload associated with completing the sound analysis and reporting process. Those carrying out analysis can be distracted, intrigued or delayed owing to the occurrence of recordings that are unfamiliar and not identifiable to them. These recordings can relate to ‘difficult to ID’ bat species, but also, often, sounds not related to bats. This can be especially true when noise triggers such as insects, small mammals or birds look like bat-related noise. Therefore, only knowing what bats sound like is not enough. It is extremely useful to know what other sources of noise look and sound like within the same soundscape. This resource will help bat workers, in whatever environment they are in, to be more confident in recognising, categorising and dismissing other sounds. The book includes a substantial downloadable sound library (.wav format) that readers can listen to by ear or process through sound analysis software. Is That a Bat? also caters for sounds that are also heard by ear alone, in the field, during the hours of darkness. These scenarios often have bat surveyors intrigued or confused as to what they are listening to. Occasionally, knowing what these sounds are could be important, or at the very least, of interest. The first chapter caters for the subject overall, including suggestions from the author as to why the subject matter is of value. It also discusses bat-related calls (including social calls) with a view to offering comparisons against the other sources of sound discussed in separate chapters. Continuing through the book, there are chapters covering the following: small mammals; amphibians; insects; birds; electrical/mechanical noise; and other noise/nuisances. Within each chapter there are sub-sections about bat detector recorded sound, sound by ear, as well as advice on techniques and methods to reduce or increase the likelihood of recording other sounds. The book concludes with associated appendices, including a ‘Problem Solving Key’ to help those encountering an unfamiliar sound to narrow it down to the likely source. With technology advancing at pace, the technical ability of the analyst is of huge importance. With a wider perspective and more knowledge, those responsible for interpreting field encounters can be more confident when making decisions about sources of sound. Apart from that, ‘knowing stuff’ makes the job far more interesting and gives the bat worker a greater appreciation of the natural world within which they are working.
A comprehensive and invaluable resource, Methods for Ecological Research on Terrestrial Small Mammals is a must-have for any ecologist working on small mammals.
The best field guide to North American mammals The best-selling field guide that "sets new standards" (New Scientist) and "makes all other field guides for mammals of the United States. . . and Canada obsolete" (Journal of Mammalogy) is now even better. Covering 20 species recognized since 2002 and including 13 new color plates, this fully revised edition of Mammals of North America illustrates all 462 known mammal species in the United States and Canada—each in beautiful color and accurate detail. With a more up-to-date species list than any other guide, improved facing-page descriptions, easier-to-read distribution maps, updated common and scientific names, and track and scat illustrations, this slim, light, and easy-to-use volume is the must-have source for identifying North American mammals. Roland Kays and Don Wilson have scoured the technical literature to pull out the key differences between similar species, and illustrated these whenever possible, making the guide useful to amateur naturalists and professional zoologists alike. Casual animal watchers will appreciate the overview of mammal diversity and the tips on identifying animals they can spy in their binoculars, while scientists will appreciate the exacting detail needed to distinguish similar species, including illustrations of shrew teeth, bat toes, and whale dorsal fins. The best-illustrated and easiest-to-use field guide to North American mammals Beautiful and accurate color illustrations of all 462 mammals found in the United States and Canada—including 20 species recognized since 2002 112 color plates—including 13 new ones Key identification information—fully revised—on facing pages The most current taxonomy/species list Fully revised, easy-to-read range maps Illustrations of tracks, scat, and whale and dolphin dive sequences
This is the only comprehensive guide to mammals in Central America and Southeast Mexico. Unlike most field guides, it covers smaller mammals in depth and also provides an extensive bibliography. In addition to detailed species accounts and range maps for all species, the book has 52 full-color plates. The 49 animal plates cover almost all the species in the region. 4 color maps are new to the second edition, detailing parks, elevations and biomes in the region.
A classic work and the first to comprehensively study this interesting life form, which has an important role in decomposing plant material. Myxomycetes (slime moulds) were once considered a special group of fungi. However they are now grouped within Amoebozoa as unicellular protists that adopt a multicellular aggregate form in certain conditions. Introductory chapters cover life-history, structure, ecology, distribution, how to find and collect material, bark culture techniques, microscopic examination, and herbarium storage of ‘slime-moulds’. The detailed accounts cover identification, keys, descriptions and illustrations. They also include notes on differences from other similar species. This is a reprint of the enlarged 2020 edition with a 20-page supplement including new species, together with 54 colour photos. It is a guide to the British and Irish species, including keys, descriptions, and illustrations showing the diagnostic features along with introductory chapters on life history, structure, ecology and distribution, collecting, techniques, and preservation.
