Britain's Butterflies is a comprehensive and beautifully designed photographic field guide to the butterflies of Britain and Ireland. Containing hundreds of stunning colour photographs, this revised and updated edition provides the latest information on every species ever recorded. It covers in detail the identification of all 59 butterfly species that breed regularly, as well as four former breeders, 10 rare migrants and one species of unknown status. The easy-to-use format will enable butterfly-watchers—beginners or experts—to identify any species they encounter. Stunning colour plates show typical views of each butterfly species, including the various forms and aberrations Detailed species profiles cover adult identification; behaviour; habitat requirements; population and conservation; egg, caterpillar and chrysalis; and status and distribution, including up-to-date maps Photographs of egg, caterpillar and chrysalis for every breeding species Sections on biology, where to look for and how to identify butterflies and other essential information

"Produced in association with ORCA"--Back cover.

One of the first engineering books to cover wavelet analysis, this classic text describes and illustrates basic theory, with a detailed explanation of the workings of discrete wavelet transforms. Computer algorithms are explained and supported by examples and a set of problems, and an appendix lists ten computer programs for calculating and displaying wavelet transforms.Starting with an introduction to probability distributions and averages, the text examines joint probability distributions, ensemble averages, and correlation; Fourier analysis; spectral density and excitation response relations for linear systems; transmission of random vibration; statistics of narrow band processes; and accuracy of measurements. Discussions of digital spectral analysis cover discrete Fourier transforms as well as windows and smoothing. Additional topics include the fast Fourier transform; pseudo-random processes; multidimensional spectral analysis; response of continuous linear systems to stationary random excitation; and discrete wavelet analysis.Numerous diagrams and graphs clarify the text, and complicated mathematics are simplified whenever possible. This volume is suitable for upper-level undergraduates and graduate students in engineering and the applied sciences; it is also an important resource for professionals.

A photographic guide to habitats, this lavishly illustrated book provides a comprehensive overview of the natural history and conservation landscape of Britain and Ireland. In essence a field guide, the book leads the reader through all the main habitat types, with information on their characteristics, extent, geographical variation, key species, cultural importance, origins and conservation. It aims to help visitors to the countryside recognize the habitats around them, understand how they have evolved and what makes them special, and imagine how they might change in the future.

From the Swallowtail to the Small Blue, the largest to the smallest, from the swooping fritillaries to the sedentary hairstreaks, the variety and color of Britain's butterflies will astonish you. To see all except the common garden butterflies, you need to know when and where to look. This book tells you. With a little preparation and planning, all of the British butterflies can be enjoyed flying in the wild. If you go to the hotspots at the right time, follow the directions given, and are willing to be patient, you should be able to discover even the rarest species. In your search, you will also explore some of the best of the British countryside. Descriptions and photographs of 66 good places to find butterflies Selection by site or species Full color throughout, with stunning images of the 66 localities, and of all the British butterfly species Illustrations on all pages Historical information about dates of discovery of species and name changes over the years At least 1 hotspot for every rare species Gazetteer with an extended list of butterfly reserves Bibliography and a full list of relevant Web sites
