The book embodies the detailed account about unique symbionts i.e. LICHENS in ecosystem monitoring. The first chapter deals with unique characteristics features of lichens which facilitate their survival in extreme climates and makes them an ideal organism for ecosystem monitoring. Biosynthesis of secondary metabolites are known to protect lichens against increasing environmental stresses therefore second chapter provides insight into various chromatographic and modern spectroscopic techniques involved in separation and characterization of lichen substances. The third chapter elaborates the criteria for selection of biomonitoring species and characters of host plant that influences lichen diversity and details about different lichen species utilized for biomonitoring. One can retrieve preliminary information about the air quality based on the lichen community structure and distribution of bioindicator species as lichen communities/indicator species provides valuable information about the natural/anthropogenic induced changes in the microclimate and land-use changes due to human activity. Therefore, for identification of species, a key to genera and species provides concise information to identify the lichen species based on their morphological and anatomical characters and chemicals present. Keys provided in Chapter 4 will help the beginners to identify some common lichen species based on the distribution in different climatic zones of India. The section also provides comprehensive information about the bioindicator communities and bioindicator species from India. Chapter 5 provides the details of factors affecting the ecosystem (natural as well as anthropogenic disturbances) and role of lichens in ecosystem monitoring in India has been discussed in detail. Chapter 6 discusses the need and utility of indicator species especially lichen biomonitoring data in sustainable forest management and conservation. The content about lichens in biomonitoring will be a valuable resource for researchers from different fields and will provide an essential reference for people interested in lichens and its role in ecosystem monitoring. The book will also hopefully popularize lichenological studies in India and will generate more active participation of lichen biomonitoring studies in management and conservation of natural resources in India.

A practical field guide to the common lichens found in the northeastern megalopolis, including New York City, Toronto, Boston/New Haven, Philadelphia, Baltimore/Washington, D.C., and as far west as Chicago Lichens are dynamic, symbiotic organisms formed by close cooperation between fungi and algae. There are over 20,000 identified species performing essential ecosystem services worldwide. Extremely sensitive to air pollution, they have returned to cities from which they were absent for decades until the air became cleaner. This guide is the first to introduce urban naturalists to over 60 of the common lichens now found in cities and urban areas throughout northeastern North America--in parks and schoolyards, on streets, and in open spaces. Divided into three sections -- lichen basics, including their biology, chemistry, morphology, and role in human history; species accounts and descriptions; and an illustrated glossary, index, and references for further reading -- the book aims to connect city dwellers and visitors with the natural world around them. The descriptions, exquisite photographs, and line drawings will enable users to enter the hidden world of lichens.

This volume focuses on the interaction of lichens with their substrate, environment and their biogeographic effects. In seventeen chapters thirty-eight authors present recent findings and developments in systematics, biodiversity, floristic studies and ecology, as well as newly described taxa, and keys to the identification of Caloplaca and xanthorioid lichens. Molecular phylogenetic analyses of several groups and genera are presented, resulting in an improved systematics of, for example, Caloplaca, Cladonia, Collema and xanthorioid lichens. The genera Arthonia and Usnea in Greece (with key) are reviewed. The volume is dedicated to Prof. Hans Martin Jahns on the occasion of his 70th birthday, featuring papers on some of his favourite fields of research, among them lichen interactions with their substrate and environment and lichen biogeography. A brief biography of Jahns, highlighting his contributions to lichenology, is included in the chapter on the nine Presidents of the International Association for Lichenology. Jahns played an important role during the past 40 years with his highly influential book, co-authored by Aino Henssen, entitled Lichenes. Eine Einführung in die Flechtenkunde. He is well-known for his extensive work and numerous publications on lichen morphology and ontogeny, particularly the development of fruiting bodies in different genera.

A comprehensive, up-to-date review of lichens as biomonitors of air pollution (bioindication, metal and radionuclide accumulation, biomarkers), and as monitors of environmental change (including global climate change and biodiversity loss) in a wide array of terrestrial habitats. Several methods for using lichens as biomonitors are described in a special section of the book.

The Lichens covers the structure and development, physiology of the intact thallus, environmental response and effects, secondary metabolic products, and symbiont interactions of lichens. This book is divided into five parts encompassing 19 chapters. It also includes appendices consist of a taxonomic scheme, methods for isolating and culturing lichen symbionts and thalli, and methods for isolating and identifying lichen substances. The first part of this book describes the original fungal cell and its development into specialized cells of which the various tissues and thalli are composed. This is followed by discussions on sexual reproduction of ascolichens and basidiolichens and on systematic criteria for the definition of taxa in different hierarchical steps. This book also explains the types of propagules produced by lichens and the submicroscopical investigations of lichens, including phycobiont and mycobionts' substructure and symbiotic relationship. The second part of this book examines the physiological aspects of lichens. It includes discussions on metal cation uptake and translocation in vascular plants and on lichens' role in rock weathering and soil formation. This part also studies photosynthetic rates and nitrogen absorption and metabolism by the intact thallus of lichens. Succeeding chapters discuss physiological and morphological responses of lichens to the most important environmental factors and the relationship of these factors to lichen distribution. Substrate preferences of lichens and their causes and implications with regard to the ecology, distribution, and taxonomy of lichens are also examined. This text also discusses lichen thalli growth, methods of measurement, and factors influencing growth. Finally, the concluding parts deal with the biosynthesis of lichen substances, secondary metabolic products, and symbiotic relations of lichens to fungi and algae. This multi-authored book is an ideal source of information for researchers, teachers, and students who wish to broaden their knowledge in the diversity of lichenology.

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.
