Birdsong is the natural soundtrack to our lives and can evoke a powerful sense of time, place and season. Often profoundly beautiful, it is also the most effective way to discover many birds, and birds' songs and calls reveal much about their lives and behaviour. However, identifying which bird is making which sound can seem challenging. With this groundbreaking and easy-to-use guide, Adrian Thomas helps you learn and identify bird sounds step by step and at your own pace. Whether you are an experienced birdwatcher or just enjoy hearing the birds in your garden, this new guide will open your ears like never before to the amazing songs and calls around you. Includes a sound guide to more than 100 songs and calls of 65 garden, woodland and farmland birds. A reference section describes in detail the sounds of a further 185 birds of Britain and north-west Europe. Beautiful colour photographs, annotated sonograms and 'test yourself' sections are also included.

Rock physics encompasses practically all aspects of solid and fluid state physics. This book provides a unified presentation of the underlying physical principles of rock physics, covering elements of mineral physics, petrology and rock mechanics. After a short introduction on rocks and minerals, the subsequent chapters cover rock density, porosity, stress and strain relationships, permeability, poroelasticity, acoustics, conductivity, polarizability, magnetism, thermal properties and natural radioactivity.

This book discusses analytic and asymptotic methods relevant to radiative transfer in dilute media, such as stellar and planetary atmospheres. Several methods, providing exact expressions for the radiation field in a semi-infinite atmosphere, are described in detail and applied to unpolarized and polarized continuous spectra and spectral lines. Among these methods, the Wiener–Hopf method, introduced in 1931 for a stellar atmospheric problem, is used today in fields such as solid mechanics, diffraction theory, or mathematical finance.

Название: RSPB Spotlight Hedgehogs
Автор: James Lowen

Год: 2018
Формат: EPUB
Размер: 115 Мб
Язык: английский / English

Much loved ... but about to be lost? The Hedgehog regularly tops polls of the UK's favourite animal, yet numbers in our countryside have halved this century. Generations of children have been captivated by Beatrix Potter's The Tale of Mrs Tiggy-Winkle, though our complex and contradictory relationship with the Hedgehog is also characterised by persecution and death. This unmistakable, spiny mammal is a 'gardener's best friend', but one that we rarely see alive and in our midst. In Spotlight: Hedgehogs, James Lowen reveals what a Hedgehog is and how it lives, unveiling the secrets of its lifestyle, such as foraging and hibernating, rolling into a ball and building a nest. He also investigates the relationship between Hedgehogs and people – from film and fun to conservation and crisps – and offers practical advice on how to find, watch and help these charming animals in the wild.

They were bestowed with magical properties in folklore, they were sought after as ingredients of witches' broth, and they are comic characters that have invaded popular culture, from Kermit the Frog to Toad of Toad Hall. Frogs and toads are charismatic members of Britain's wildlife. But what do you really know about them? Scratch beneath the surface, and you will discover some of nature's weirdest creatures, amphibians whose ecology we are only now coming to understand. Spotlight Frogs and Toads is a compelling account of Britain's four native amphibian species: the Common Frog, the Pool Frog, the Common Toad and the rare and secretive Natterjack Toad. New research suggests that, in the next ten years, three out of four UK species are likely to be listed as threatened. Revealing a host of secrets, including how they migrate, what they eat, and how they got to the UK in the first place, Jules Howard inspires us all to look down, rather than up, in spring.

В книге приводятся общие сведения о пустынях земного шара: закономерности их образования и географического распространения, особенности природы, классификация. Дается также физико-географическая характеристика различных пустынь мира по континентам и отдельным регионам. Большое внимание уделено хозяйственному освоению пустынь и проблеме "пустыня и человек" - современному антропогенному воздействию на пустыни, процессам опустынивания и охране их природы
