Cave exploration has uncovered archaeological finds which have enhanced our understanding of human evolution, and fossil remains, such as woolly mammoths, which reveal something of the Pleistocene animal world. But perhaps most fascinating of all is the living natural history of caves.There are few unexplored places on earth, but caves still offer countless opportunities for discovery. From new passages to whole new cave systems, significant finds are still being made – recent exploration in South Wales revealed Britain's largest passageways.Caves are formed over many thousands of years, as subterranean waters seep slowly through the crevices of the buckled and twisted laters of limestone rocks. These cracks develop into fantastically shaped passages which stretch for miles, huge caverns housing vast, still lakes and deep potholes through which icy waterfalls tumble. Within them form arrays of stalactites and stalagmites, delicately twirling helictites, slender pillars of calcite and crystal pools. And it is these wonders that have encourages the adventurers who have explored and charted this underground world – descending on ropes into gaping pits, crawling and digging their way along tunnels and diving through freezing torrents to do so.Cave exploration has uncovered archaeological finds which have enhanced our understanding of human evolution, and fossil remains, such as woolly mammoths, which reveal something of the Pleistocene animal world. But perhaps most fascinating of all is the living natural history of caves.The study of cave biology is still in its infancy. Speculation and controversy abound, cavernicolous communities remain under-recorded and new species await discovery in most subterranean habitats. But in this book, Philip Chapman has drawn together his expert knowledge of caves and cave life to present an outstanding and cohesive account of what is now known in this extraordinary world, which for so many has remained unknown for so long.

An enchanting biography of the most resonant – and most necessary – chemical element on Earth.Carbon. It is the building block of every cell that makes up every living thing. It is the essential component of the food we eat, the fuel we burn, the wood we use and the air we breathe. It is worth billions as a luxury and half a trillion as a necessity, but there are still mysteries to be solved about the element that can be both diamond and coal. Where does it come from, what does it do, and why, above all, does life need it?In Symphony in C, leading carbon scientist Robert M. Hazen takes us on a vibrant journey through the origin and evolution of life’s most widespread element. The story unfolds in four movements – Earth, Air, Fire and Water – and transports us through nearly 14 billion years of cosmic history, explaining how carbon is formed in the hearts of stars and why all life forms – earthbound or alien – use it as the basis of their biology. Symphony in C is a sweeping chronicle of carbon from its birth amidst the stars to its unknowable life cycle deep within the Earth’s core and its role in the evolution of all life in the universe.

The gull is a familiar sight by the seaside, and one of the most recognisable bird species, but most people know surprisingly little about the lives and habits of these seafaring birds. John C. Coulson remedies this with a comprehensive overview of the gull.There are more than 50 known species of gulls, and many of these are well-adapted to living in urban areas and in close proximity to humans. But there are also less familiar species to discover, which keep their distance from beachgoers. This long-overdue addition to the New Naturalist library explains the thorny issues of gull taxonomy and classification, then introduces readers to what it means to be a gull, physically and genetically. Chapters are divided by larger gull groups, and within these, distribution, lifecyles and behaviours are examined, as well as acclimation to the human world. Colour photography throughout offers ample opportunity to get a sense of the variation within the gull group, and makes this book a pleasure to look through.

Gardens make a significant contribution to the amount of urban green space and are the main contributors to urban biodiversity. Birds are one of the most visible components of this urban biodiversity, and many of us enjoy attracting wild birds into our gardens.This timely addition to the New Naturalist Library examines the ways in which birds use gardens, revealing the many new discoveries that are being made and explaining why individual species of bird use gardens in the ways that they do. Why, for example, do Blackcaps now winter in UK gardens – favouring those in the southwest and those that are urban in nature – and why do Siskins increase their use of garden feeders on damp winter days? With a growing human population, the process of urbanisation is set to continue and it is important to recognise the impacts that urbanisation will have on bird populations and the community of species making a living within the built environment.Although many people do not regard themselves as birdwatchers, most of those who seek to attract wild birds into their gardens do so because they enjoy watching them. Some have taken their interest further by becoming involved in citizen science projects that have helped to develop our understanding of how and why birds use our gardens and the resources that they provide. This research demonstrates the role that gardens play in the ecology of many wild bird populations and reveals insights that continue to fascinate a growing audience, increasingly interested in the wildlife that lives alongside them.

A complete natural history of the Hebrides – an area of great natural beauty, which draws back thousands of visitors year after year to its wonderful scenery and abundant wildlife.The Hebrides is an area of great natural beauty, which draws back thousands of visitors year after year to its wonderful scenery and abundant wildlife. Yet, until now, there has been no up-to-date, complete natural history for its many followers to refer to. This title fills the gap.In a style at once both readable and informative the Drs. J. M. and I. L. Boyd cover every aspect of the islands. Starting with a clear explanation of the geology, climate and hydrography, they move on to a fascinating description of the many varies habitats, from the sea and inland waters through to woodlands and moor and hill. Part II deals with the characteristics of individual islands and their species, while in part III the islands are discussed in the context of their relation to people – starting with the old naturalists, and ending on a topical note with the current interest in conservation.
