Book Description
The ubiquitous fungi are little known and vastly underappreciated. Yet, without them we wouldn’t have bread, alcohol, cheese, tofu, or the unique flavors of mushrooms, morels, and truffles. We can’t survive without fungi. The Kingdom Fungi provides a comprehensive look at the biology, structure, and morphological diversity of these necessary organisms. It sheds light on their ecologically important roles in nature, their fascinating relationships with people, plants, and animals, and their practical applications in the manufacture of food, beverages, and pharmaceuticals. The book includes information about “true” fungi, fungus-like creatures (slime molds and water molds), and a group of “composite” organisms (lichens) that are more than just fungi. Particular attention is given to examples of fungi that might be found in the home and encountered in nature. The Kingdom Fungi is a useful introductory text for naturalists, mycologists, and anyone who wants to become more familiar with, and more appreciative of, the fascinating world of fungi.

Book Description
Terricolous lichens, a habitat specialist group of lichens play a vital role in maintenance and ecological stability of soil crusts with reference to their physical stability, hydrology and growth of soil microflora. Terricolous Lichens in India, Volume 2: Morphotaxonomic Studies is the first lichenological study of this functional group. Based upon extensive field collections and the investigation of approximately 4,500 specimens preserved in various national and international herbariums, Terricolous Lichens in India: Volume 2: Morphotaxonomic Studies focuses on the morphotaxonomy of terricolous lichens in India. Divided into two chapters, the first chapter describes the basics of soil lichen curation from Indian habitats, presents the various morpho-anatomical and chemical techniques for taxonomic identification, and introduces the morpho-anatomical features of terricolous lichens. The second chapter focuses on the taxonomy of 312 terricolous lichen species and includes detailed identification keys and taxonomic descriptions. Written by experts in the field and complemented with over 50 color photoplates and maps, Terricolous Lichens in India: Volume 2: Morphotaxonomic Studies is a valuable resource for researchers and students interested in the field of lichenology.

Book Description
DIVPerhaps the world’s most distinctive tree, ginkgo has remained stubbornly unchanged for more than two hundred million years. A living link to the age of dinosaurs, it survived the great ice ages as a relic in China, but it earned its reprieve when people first found it useful about a thousand years ago. Today ginkgo is beloved for the elegance of its leaves, prized for its edible nuts, and revered for its longevity. This engaging book tells the full and fascinating story of a tree that people saved from extinction—a story that offers hope for other botanical biographies that are still being written./divDIV /divDIVInspired by the historic ginkgo that has thrived in London’s Kew Gardens since the 1760s, renowned botanist Peter Crane explores the evolutionary history of the species from its mysterious origin through its proliferation, drastic decline, and ultimate resurgence. Crane also highlights the cultural and social significance of the ginkgo: its medicinal and nutritional uses, its power as a source of artistic and religious inspiration, and its importance as one of the world’s most popular street trees. Readers of this extraordinarily interesting book will be drawn to the nearest ginkgo, where they can experience firsthand the timeless beauty of the oldest tree on Earth./div

Book Description
The Oldest Living Things in the World is an epic journey through time and space. Over the past decade, artist Rachel Sussman has researched, worked with biologists, and traveled the world to photograph continuously living organisms that are 2,000 years old and older. Spanning from Antarctica to Greenland, the Mojave Desert to the Australian Outback, the result is a stunning and unique visual collection of ancient organisms unlike anything that has been created in the arts or sciences before, insightfully and accessibly narrated by Sussman along the way. Her work is both timeless and timely, and spans disciplines, continents, and millennia. It is underscored by an innate environmentalism and driven by Sussman’s relentless curiosity. She begins at “year zero,” and looks back from there, photographing the past in the present. These ancient individuals live on every continent and range from Greenlandic lichens that grow only one centimeter a century, to unique desert shrubs in Africa and South America, a predatory fungus in Oregon, Caribbean brain coral, to an 80,000-year-old colony of aspen in Utah. Sussman journeyed to Antarctica to photograph 5,500-year-old moss; Australia for stromatolites, primeval organisms tied to the oxygenation of the planet and the beginnings of life on Earth; and to Tasmania to capture a 43,600-year-old self-propagating shrub that’s the last individual of its kind. Her portraits reveal the living history of our planet—and what we stand to lose in the future. These ancient survivors have weathered millennia in some of the world’s most extreme environments, yet climate change and human encroachment have put many of them in danger. Two of her subjects have already met with untimely deaths by human hands. Alongside the photographs, Sussman relays fascinating – and sometimes harrowing – tales of her global adventures tracking down her subjects and shares insights from the scientists who research them. The oldest living things in the world are a record and celebration of the past, a call to action in the present, and a barometer of our future.

Book Description
Grasslands are an important element of European nature. About half of Europe's endemic species depend on grasslands, whether in mountains, lowlands, river plains or coastal areas. Many grasslands originate in traditional agricultural landscapes. Modern intensification, however, brings many of these ecosystems under threat. 'Grasslands in Europe' is a tribute to these important ecosystems. It was written by an international team of grassland experts, who describe twenty-four case studies from countries in all of Europe - ranging from the grasslands of Gotland and #land (Sweden) to the Spanish Dehesa, and from the hay meadows of the British Pennine Dales to the steppes of Turkish Anatolia. Together, these case studies provide a fascinating glimpse into the various European grasslands, their value for nature, culture and agriculture, and the threats they are facing today. The accessible text as well as the rich illustrations will appeal to a wide audience. Grasslands in Europe contains a large number of stunning full-colour photographs of grassland landscapes, species and cultural history. It also contains many maps and infographics. Thematic chapters provide essential background information on topics such as grassland fauna, the history of agriculture, grassland communities, and the connection between grasslands and climate. The book also analyses the opportunities and risks of EU policy to conserve these grasslands. It offers a farmer-centred outlook to manage and to maintain the European grasslands of high nature value.
