Book Description
Lichens are a unique form of plant life, the product of a symbiotic association between an alga and a fungus. The beauty and importance of lichens have long been overlooked, despite their abundance and diversity in most parts of North America and elsewhere in the world. This stunning book--the first accessible and authoritative guidebook to lichens of the North American continent--fills the gap, presenting superb color photographs, descriptions, distribution maps, and keys for identifying the most common, conspicuous, or ecologically significant species. The book focuses on 805 foliose, fruticose, and crustose lichens (the latter rarely included in popular guidebooks) and presents information on another 700 species in the keys or notes; special attention is given to species endemic to North America. A comprehensive introduction discusses the biology, structure, uses, and ecological significance of lichens and is illustrated with 90 additional color photos and many line drawings. English names are provided for most species, and the book also includes a glossary that explains technical terms. This visually rich and informative book will open the eyes of nature lovers everywhere to the fascinating world of lichens.

Book Description
It is currently impossible to grow lichens under controlled conditions in the laboratory in sufficient quantity for physiological experiments. Lichen growth is slow and conditions which might accelerate the process tend to favour either the algal or fungal partner, resulting in the breakdown of balance symbiosis. Lichen physiologists are therefore forced to use field-grown material with all the problems associated with the unknown influences of unpredictable and unreproducible climatic conditions. Study of major biochemical topics, such as the nature of the carbohydrate and nitrogenous compounds passing between the symbionts, is less influenced by climatic conditions than the intrinsic nature of the symbionts and many advances have been made in these areas. Recently, the challenge of using field-grown plant material, the physiological status of which is intimately linked to environmental conditions, has proved to be a stimulus rather than a hindrance to a number of research groups. The occurrence of lichens in extreme habitats has prompted a number of field and laboratory studies with material from such diverse localities as the cold deserts of Antarctica and the temperate rain forests of the New Zealand bush. A comparative approach, using contrasted species or habitats from a particular geographical region has yielded much information and an appreciation of the variety of physiological adaptations which may exist. The close linkage between morphology and physiology is now being directly demonstrated, as is the relevance of ultrastructural information.

Book Description
Based on the acclaimed reference Lichens of North America, this resource for the classroom, field, and laboratory presents updated and expanded keys for the identification of over 2,000 species of lichens indigenous to the continent, twice the number covered by previous keys. The book includes a glossary illustrated with photographs by Sylvia Duran Sharnoff and Stephen Sharnoff and drawings by Susan Laurie-Bourque, all from the original book. The revised keys are an indispensable identification tool for botanists, students, scientists, and enthusiasts alike.--COVER.

Book Description
This revised and extended edition provides in-depth insights into the benefits and untapped potential of lichen-derived bioactive compounds. The whole spectrum of these compounds’ biological and medical functions, from antibiotic to antiviral and anti-carcinogenic properties, is presented. In addition, a new chapter discusses the anti-neurodegenerative and anti-diabetic activities of lichenic secondary metabolites. Given its scope, the book offers a valuable asset for students and researchers in this field.

Book Description
“A Way to Garden prods us toward that ineffable place where we feel we belong; it’s a guide to living both in and out of the garden.” —The New York Times Book Review For Margaret Roach, gardening is more than a hobby, it’s a calling. Her unique approach, which she calls “horticultural how-to and woo-woo,” is a blend of vital information you need to memorize and intuitive steps you must simply feel and surrender to. In A Way to Garden, Roach imparts decades of garden wisdom on seasonal gardening, ornamental plants, vegetable gardening, design, gardening for wildlife, organic practices, and much more. She also challenges gardeners to think beyond their garden borders and to consider the ways gardening can enrich the world. Brimming with beautiful photographs of Roach’s own garden, A Way to Garden is practical, inspiring, and a must-have for every passionate gardener.

Book Description
Understand the properties and applications of one of the world’s most ubiquitous flora Lichen is a single entity comprising two or more organisms—most typically algae and fungus—in a symbiotic relationship. It is one of the planet’s most abundant categories of flora, with over 25,000 known species across all regions of the globe. Lichens’ status as a rich source of bioactive metabolites and phytochemicals, as well as their potential as bio-indicators, has given them an increasingly prominent role in modern research into medicine, cosmetics, food, and more. Chemistry, Biology and Pharmacology of Lichen provides a comprehensive overview of these bountiful flora and their properties. It provides not only in-depth analysis of lichen physiology and ecology, but also a thorough survey of their modern and growing applications. It provides all the tools readers need to domesticate lichen and bring their properties to bear on some of humanity’s most intractable scientific problems. Chemistry, Biology and Pharmacology of Lichen readers will also find: Applications of lichen in fields ranging from food to cosmetics to nanoscience and beyond Detailed discussion of topics including lichen as habitats for other organisms, lichens as anticancer drugs, antimicrobial properties of lichen, and many more Detailed discussion on key bioactive compounds from lichens Chemistry, Biology and Pharmacology of Lichen is ideal for scientists and researchers in ethnobotany, pharmacology, chemistry, and biology, as well as teachers and students with an interest in biologically important lichens.

Book Description
The purpose of this book is to provide reference material that includes current developments along with a future outlook on the topic. It is divided into two sections; "Morphological Overview and Extraction Prospects" and "Trends and Applications". Part I contains four chapters that provide an overview and systematically discuss the physical morphology, suitability and extraction aspects of lichens and their secondary metabolites. Part II includes eight chapters that give in-depth insights on recent and valuable applications of lichen and their obtained products in several applied sectors, including ethnopharmacology, therapeutics, paper and dye, nutraceuticals, cosmetics, herbal industries, etc.
