Mushrooms and Toadstools (Collins New Naturalist Library, Book 7)
Mushrooms and Toadstools (Collins New Naturalist Library, Book 7)
John Ramsbottom
¥456.66
Britain's neglect of fungi as table delicacies has perhaps been responsible for our surprising ignorance of the natural history of such fascinating plants. This edition is exclusive to newnaturalists.com Puff-balls, more than a foot in diameter; mouls in jam-pots; dry rot; truffles; these are examples of the wide range of the Group, comprising over 100,000 species. Many are of economic importance – for example, the rusts that attack wheat and other crops, and the yeasts which ferment beer – and there are others of great biological interest, such as the mycorrhizal fungi which live in association with the roots of forest trees, orchids and other plants, and help them to absorb food from the soil. Penicillin, of course, has become a household word, and this book's final chapter on the industry is one of the best short accounts of the subject yet writtern. Dr. Ramsbottom was for many years Keeper of Botany at the Natural History Museum, and has devoted his life to the study of fungi in all their aspects. He is equally at home in the field, the laboratory and the library. One of the special features of Mushrooms and Toadstools is the wealth of historical allusion to fungi extracted from old books. Set out in a style reminiscent of Robert Burton, this volume can truly be described as a 20th century Anatomy of Toadstool. Indeed, in fairy rings, science and superstition have gone hand in hand to produce a lively story of alternating surmise and research – and even today a full and final explanation of these mysterious rings has not yet been made. Many of the larger toadstools are brightly coloured and lend themselves admirably to colour photography, as shown by the 80 remarkable illustrations by Mr Paul de Laszlo.
Insect Migration (Collins New Naturalist Library, Book 36)
Insect Migration (Collins New Naturalist Library, Book 36)
C. B. Williams
¥456.66
Highlighting the significance of the widespread distribution of the migratory habit throughout the insect world. This edition is exclusive to newnaturalists.com This is a pioneer book, a real milestone in the progress of biology. Only in recent years have the scientists begun to realise the significance of the widespread distribution of the migratory habit throughout the insect world. Dr. Williams's own personal observations and adventures have played a fundamental part in the wakening of human consciousness to the extent to which insects migrate. His opportunities of studying the problem in remote corners of the world - such as British Guiana, Costa Rica, Egypt, Tanganyika and the Pyrenees - make the book as exciting as a world detective story. For Insect Migration deals with the subject on an international basis, with Britain - the home of the development of the present theories - as the natural peg on which a biological problem belonging to the world can properly be hung. From 1932 to 1955 C. B. Williams was chief entomologist at the Rothamsted Experimental Station. This book is the distillation of a subject which has occupied him for nearly the whole of his life. His theories are marshalled and summarised with modesty, economy and skill. The New Naturalist is honoured to publish what will certainly prove to be, above all things, the stimulus for new search and fresh discoveries.
The Folklore of Birds (Collins New Naturalist Library, Book 39)
The Folklore of Birds (Collins New Naturalist Library, Book 39)
Edward A. Armstrong
¥456.66
Tracing the magico-religious beliefs surrounding birds as far back in time as is possible, to the cultures in which these beliefs arose. This edition is exclusive to newnaturalists.com Edward A Armstrong is already known to readers of the New Naturalist as the author of the remarkable study on the wren. His wide scholarship and talents have fitted him outstandingly for this book, which could only have been written by a man with his deep understanding, not only of ornithology, but of social anthropology, psychology and comparative religion. Mr Amstrong has selected a number of familiar birds - such as the swan, the raven, the owl, the robin and the wren - and has traced magico-religious beliefs concerning them as far back as possible to the cultures in which these beliefs arose. With the scientist’s eye and methods of analysis he has examined the development of myth and ritual with originality and ingenuity. Many odd and interesting facts are cited, and explanations are given, for example of the customs of breaking the wish-bone, and of fables concerning weather-prophet birds and the generation of the Barnacle Goose from shell-fish. This book is the first treatment of a group of folklore beliefs as a series of artefacts are treated by an archaeologist, classifying them in order according to epochs. Archaeological data, as well as oral and literary traditions, have been used to illustrate the origins and significance of the current folklore. The illustrations are of exceptional quality and consist of over 140 carefully chosen photographs and line drawings from worldwide sources.
Finches (Collins New Naturalist Library, Book 55)
Finches (Collins New Naturalist Library, Book 55)
Ian Newton
¥456.66
This illustrated survey of finch behaviour is a thorough, non-technical account of the habits of these birds throughout the world. Greenfinches nest in plantations, large shrubby gardens and churchyards with lots of evergreens, thickets and tall hedges. After breeding, goldfinches forage on waste land, overgrown rubbish dumps, neglected allotments of food, and rough pastures. Bullfinches, in their breeding season, develop in the floor of their mouths special pouches in which food for the young is retained. These pouches open, one on each side of the tongue and, when full, extend back under the jaws as far as the neck, when they together hold about one cubic centimetre of food. Cocks of the Chaffinch and Brambling species sing in the breeding season to repel other cocks and attract hens. This illustrated survey of finch behaviour is a thorough, non-technical account of the habits of these birds throughout the world. Dr. Newton uses his extensive bird-watching experience and knowledge of the published literature to document the main patterns of feeding, development of feathers, breeding, and migration. As a result, he presents the changing relationship of the birds to their environment. The author is on the staff of the Nature Conservancy at Edinburgh, Scotland. His several scientific papers on finches have appeared in Birds, Journal of Animal Ecology and other scholarly periodicals.
British Tits (Collins New Naturalist Library, Book 62)
British Tits (Collins New Naturalist Library, Book 62)
Christopher Perrins
¥456.66
In addition to dealing with the general biology and behaviour of the birds, Dr Perrins gives full attention to such things as their social lives, their intelligence and adaptiveness, and their puzzling ability to adjust their population sizes to the future availability of food. This edition is exclusive to newnaturalists.com Because of their ubiquity and apparent boldness, the tits are among the most easily observed, and the most popular, of all British birds. The Blue Tit, particularly, is an attractive and confident bird and will arrive at a well-stocked bird table, or at a bag of peanuts outside a window, within a few minutes of its being set out. Curiously, little has been written about tits for the general naturalist. In this book, Christopher Perrins, who succeeded the late David Lack at the Edward Grey Institute of Ornithology in Oxford, sets out to remedy this omission. Dr Perrins has spent many years studying these small birds in great detail and has himself made many important discoveries about their lives and behaviour. The book deals with seven species of tit. These include the six members of the true tits - Coal, Great, Blue, Crested, Marsh and Willow Tits - as well as the more distantly related Long-tailed Tit. In addition to dealing with the general biology and behaviour of the birds, Dr Perrins gives full attention to such things as their social lives, their intelligence and adaptiveness, and their puzzling ability to adjust their population sizes to the future availability of food. Dr Perrin's study demonstrates that there is much unsuspected complexity - some of it still not clearly understood - in the lives of even the most popular of groups of birds; as such it will be of interest to every birdwatcher, amateur and professional alike.
Farming and Wildlife (Collins New Naturalist Library, Book 67)
Farming and Wildlife (Collins New Naturalist Library, Book 67)
Kenneth Mellanby
¥456.66
Farming and Wildlife argues forcefully that wild species are, in fact, beneficial to the land as a whole: without them its productivity will fall and farming will inevitably suffer. This edition is exclusive to newnaturalists.com Farming and wildlife affect each other in many, often subtle, ways. Yet most recent developments in farming have been harmful to wild plants and animals. As the land is made to yield more, so rare species become rarer or extinct, and even common ones are now absent from large areas of the country. This timely and provocative book argues forcefully that wild species are, in fact, beneficial to the land as a whole: without them its productivity will fall and farming will inevitably suffer. The main changes in farming practice and their environmental effects are dealt with systematically. Successive chapters discuss arable cropping, grassland management, animal husbandry, hedgerow removal, land drainage and the use of pesticides. Considered also are the care of the soil and its inhabitants - important and often overlooked forms of wildlife - possible damage to livestock by diseases of wild animals, and the effects of hunting and shooting. Professor Mellanby writes throughout with an understanding of the problems of both farmers and conservationists. This is a most persuasive account of why they should now work together to preserve the countryside's fauna and flora. Professor Kenneth Mellanby is the author of the highly acclaimed New Naturalist volume Pesticides and Pollution. He is the Founder-Director of the Monks Wood Experimental Station, which was the main research station of the Nature Conservancy, Chairman of the Watch Trust, President of the Cambridgeshire branch of the Ramblers Association, and has for many years been closely involved in all aspects of farming and conservation.

The Natural History of Wales (Collins New Naturalist Library, Book 66)
The Natural History of Wales (Collins New Naturalist Library, Book 66)
William. M. Condry
¥456.66
This book is an attempt to survey the natural history of the whole of Wales. It therefore covers such areas as Snowdonia and the Brecon Beacons as well as the spectacularly beautiful Pembrokeshire coast and the less well-known but no less interesting areas of mid-Wales. Wales is a country of great geographical and biological diversity, a largely mountainous land whose eastern scarps overlook the richer plains of Mercia. William Condry is an acute observer of the potentialities of terrain, and particularly in respect of wildlife habitats. The author of the distinguished volume on Snowdonia in the New Naturalist series, he is the ideal person to write about one of the best-known and best-loved parts of Great Britain. This book is an attempt to survey the natural history of the whole of Wales. It therefore covers such areas as Snowdonia and the Brecon Beacons as well as the spectacularly beautiful Pembrokeshire coast and the less well-known but no less interesting areas of mid-Wales. Describing each kind of terrain in turn, William Condry has explored and surveyed the face of this unique land as few others have done. Beginning with corries, crags and summits, he goes on to consider moorlands, mires and conifers. There then follow rivers, lakes and marshes; the native woodlands; limestone flora; farmlands, villages and estates; the industrial scene; and finally perhaps the most striking terrain of all, the coast. This encompasses polders, peatlands, beaches, dunes and estuaries as well as cliffs, headlands and island. Within each of these areas William Condry brings a wealth of experience to bear on the more obvious aspects of wildlife - flowering plants and ferns, mammals, birds, fish, reptiles and amphibians. Important rarities such as the Snowdon lily or the red kite are, of course, included, but always with the intention of establishing a proper respect for their conservation. Affectionate and thoroughly informative, full of insights into local history and always a delight to read, this is a magnificent introduction to Wales and its countryside.
Ferns (Collins New Naturalist Library, Book 74)
Ferns (Collins New Naturalist Library, Book 74)
Christopher N. Page
¥456.66
Ferns gives the reader an introduction to the reasons for the variety of ferns in the British Isles, as well as the history of their development within this landscape and their use by man. This edition is exclusive to newnaturalists.com Ferns, horsetails and clubmosses, or to use their technical term the Pteridophyta, are a fascinating area of the British flora that ranged from the prehistoric-looking horsetails to the delicate beauty of the Aspleniaceae family (otherwise known as the spleenworts and familiar inhabitants of many a conservatory). Ferns are ubiquitous on this damp island, but often overlooked, overshadowed by the interest in the technicolour of our flowering plants. This book gives the reader an introduction to the reasons for the variety of ferns in the British Isles, as well as the history of their development within this landscape and their use by man. Taking each major habitat, Dr Page details which species of ferns are most likely to be encountered and why. Using numerous examples, he also shows how some species have become highly adapted to their environment using a whole range of strategies varying from the ordinary to the bizarre. Ferns follows in the distinguished New Naturalist series tradition of investigative natural history, drawing from the latest field studies and research, and is the most authoritative, up-to-date and in-depth survey of this part of the British flora available.
British Freshwater Fish (Collins New Naturalist Library, Book 75)
British Freshwater Fish (Collins New Naturalist Library, Book 75)
P. S. Maitland,R. N. Campbell
¥456.66
An in-depth look at the fish that inhabit the fresh waters of Britain and Ireland. These include famous members of the salmon family, such as the Atlantic Salmon and the Brown Trout, and the obscure whitefish, species of which are confined to just a few lakes. This edition is exclusive to newnaturalists.com Fish have been a highly sought after part of the British fauna since Dame Juliana Berners wrote the first fishing book in 1486, but have long been overlooked by naturalists as a part of the British countryside. In this new volume in the New Naturalist series, Dr Peter Maitland and Niall Campbell, who have both spent a lifetime studying and catching fish, take an in-depth look at the fish that inhabit the fresh waters of Britain and Ireland. These include famous members of the salmon family, such as the Atlantic Salmon and the Brown Trout, and the obscure whitefish, species of which are confined to just a few lakes. The information that the authors uncover gives a comprehensive overview of the life cycle of fish, whether mundane spawning or the complex migrations of the Eel and Sea Trout, as well as details on diet, behaviour and ecology. The book also contains the most up to date identification key to both the families and individual species of fish, allowing every species of freshwater fish to be conclusively identified. As well as detailed de*ions of each family, there are also seven chapters on more general subject. These include chapters on fish conservation and the future of the fish fauna in our country: a sign of the change in status of fish from the pursued to the studied.

Enduring Importance of Leo Strauss
Enduring Importance of Leo Strauss
Lampert, Laurence
¥453.22
The Enduring Importance of Leo Strauss takes on the crucial task of separating what is truly important in the work of Leo Strauss from the ephemeral politics associated with his school. Laurence Lampert focuses on exotericism: the use of artful rhetoric to simultaneously communicate a socially responsible message to the public at large and a more radical message of philosophic truth to a smaller, more intellectually inclined audience. Largely forgotten after the Enlightenment, exotericism, he shows, deeply informed Strauss both as a reader and as a philosophic writer-indeed, Lampert argues, Strauss learned from the finest practitioners of exoteric writing how to become one himself.Examining some of Strauss's most important books and essays through this exoteric lens, Lampert reevaluates not only Strauss but the philosophers-from Plato to Halevi to Nietzsche-with whom Strauss most deeply engaged. Ultimately Lampert shows that Strauss's famous distinction between ancient and modern thinkers is primarily rhetorical, one of the great examples of Strauss's exoteric craft. Celebrating Strauss's achievements while recognizing one main shortcoming-unlike Nietzsche, he failed to appreciate the ramifications of modern natural science for philosophy and its public presentation-Lampert illuminates Strauss as having even greater philosophic importance than we have thought before.?
Operas of Giuseppe Verdi
Operas of Giuseppe Verdi
Basevi, Abramo
¥453.22
Abramo Basevi published his study of Verdi's operas in Florence in 1859, in the middle of the composer's career. The first thorough, systematic examination of Verdi's operas, it covered the twenty works produced between 1842 and 1857-from Nabucco and Macbeth to Il trovatore, La traviata, and Aroldo. But while Basevi's work is still widely cited and discussed-and nowhere more so than in the English-speaking world-no translation of the entire volume has previously been available. The Operas of Giuseppe Verdi fills this gap, at the same time providing an invaluable critical apparatus and commentary on Basevi's work. ?As a contemporary of Verdi and a trained musician, erudite scholar, and critic conversant with current and past operatic repertories, Basevi presented pointed discussion of the operas and their historical context, offering today's readers a unique window into many aspects of operatic culture, and culture in general, in Verdi's Italy. He wrote with precision on formal aspects, use of melody and orchestration, and other compositional features, which made his study an acknowledged model for the growing field of music criticism. Carefully annotated and with an engaging introduction and detailed glossary by editor Stefano Castelvecchi, this translation illuminates Basevi's musical and historical references as well as aspects of his language that remain difficult to grasp even for Italian readers.?Making Basevi's important contribution to our understanding of Verdi and his operas available to a broad audience for the first time, The Operas of Giuseppe Verdi will delight scholars and opera enthusiasts alike.
Radium and the Secret of Life
Radium and the Secret of Life
Campos, Luis A.
¥453.22
Before the hydrogen bomb indelibly associated radioactivity with death, many chemists, physicians, botanists, and geneticists believed that radium might hold the secret to life. Physicists and chemists early on described the wondrous new element in lifelike terms such as "e;decay"e; and "e;half-life,"e; and made frequent references to the "e;natural selection"e; and "e;evolution"e; of the elements. Meanwhile, biologists of the period used radium in experiments aimed at elucidating some of the most basic phenomena of life, including metabolism and mutation.From the creation of half-living microbes in the test tube to charting the earliest histories of genetic engineering, Radium and the Secret of Life highlights previously unknown interconnections between the history of the early radioactive sciences and the sciences of heredity. Equating the transmutation of radium with the biological transmutation of living species, biologists saw in metabolism and mutation properties that reminded them of the new element. These initially provocative metaphoric links between radium and life proved remarkably productive and ultimately led to key biological insights into the origin of life, the nature of heredity, and the structure of the gene. Radium and the Secret of Life recovers a forgotten history of the connections between radioactivity and the life sciences that existed long before the dawn of molecular biology.
