Book Description
As an intricate association between a fungus and one or more green algae or cyanobacteria, lichens are one of the most successful examples of symbiosis. These fascinating organisms survive extreme desiccation and temperatures. They are adapted to a great variety of habitats, from coastal fog zones of deserts to intertidal zones, from plant leaves in tropical rain forests to the glacial moraines of the Himalayas, and they are dominant components of communities in circumpolar ecosystems. Possibly, because of their tendency to grow in nutrient-poor habitats, lichens are extremely efficient accumulators of atmospherically deposited pollutants, and are therefore widely used to monitor environmental pollution. The wide range of secondary products only found in lichens show pharmaceutically interesting fungicidal, antibacterial and antiviral properties. Lichens are extremely difficult to culture, grow very slowly, and their secondary metabolites very often complicate the analyses of other compounds. As a result, they require special techniques. This manual provides well-tested protocols, including tissue culture protocols and methods for studying lichen ultrastructure, (eco)physiology, primary and secondary compounds, and nucleic acids. Protocols for using lichens to monitor environmental pollution and to document lichen biodiversity are also provided. Special terms used in lichenology are explained in a glossary.

These fascinating organisms survive extreme desiccation and temperatures. They are adapted to a great variety of habitats, from deserts to intertidal zones, from tropical rain forests to the peaks of the Himalayas and to circumpolar ecosystems. Lichens are extremely efficient accumulators of atmospherically deposited pollutants, and are therefore widely used to monitor environmental pollution. Their wide range of secondary products show pharmaceutically interesting fungicidal, antibacterial and antiviral properties. Lichens are extremely difficult to culture. This manual provides well-tested tissue culture protocols, protocols for studying lichen ultrastructure, (eco)physiology, primary and secondary compounds, and for using lichens as bioindicators.

Book Description
Lichens are one of several forest health indicators sampled every year for a subset of plots on the permanent grid established by the Forest Inventory and Analysis (FIA) Program of the U.S. Department of Agriculture Forest Service. This report reviews analysis procedures for standard FIA lichen indicator data. Analyses of lichen data contribute to state, regional, and national reports that evaluate spatial pattern and temporal trends in forest biodiversity, air quality, and climate. Data collection and management follow standard national protocols. A lichen species richness index (the number of species per FIA plot) is available for all areas soon after data collection. Air quality and climate indexes (for defined regional gradients and based on lichen species composition at plots) are developed from an FIA lichen gradient model. Critical steps in standard data analysis include screening plots to exclude biased data, selection of appropriate populations, then analysis, presentation, and interpretation of data.

Book Description
This book discusses in detail molecular, mycobiont culture, biomonitoring and bioprospection of lichens, providing insights into advances in different fields of lichenology by applying modern techniques and approaches and examining how their application has enhanced or changed classical approaches. It offers a valuable resource, especially for beginners, students and researchers from different academic backgrounds interested in the study of lichens. In recent years, the introduction of modern analytical techniques and approaches has significantly improved our understanding of the environment, including lichens. Lichens are unique organisms which possess untapped potential as effective and reliable bioindicators, sources of therapeutic phytochemicals, and as excellent extremophiles. The unique and peculiar characteristics of lichens underline the need for a multidimensional approach to explore their potential in various fields of environment science, botany and chemistry. Modern techniques, especially molecular techniques, have greatly enriched the field of lichen taxonomy and its position in the plant kingdom, revealing little-known species and exploring their evolutionary history, while multivariate analysis and GIS approaches have established lichens as an ideal and reliable tool for monitoring air pollution. Advanced culture techniques have expanded the pharmacological applications of lichens, which was formerly restricted due to their small biomass. The advent of sophisticated analytical instrumentation has now facilitated the isolation and characterization of lichens’ bioactive constituents, even in lower concentrations, as well as the estimation of their stress responses at different levels of pollution. As lichen diversity is adversely affected by increasing air pollution, there is a pressing need to develop effective management practices to conserve, restore and document lichen diversity.

Book Description
Ginny Chandoha hasn't just written a book about Lichen Sclerosis, it's also a book about what we in the naturopathic profession call "nature cure." If you remove the obstacles that prevent your body from working correctly, it will tend to fix itself. The mass of harmful substances that we put in and on our bodies is staggering. As Ginny points out, if you feed yourself well and quit dousing yourself in toxins, you will be well on your way to feeling better. And if you do have Lichen Sclerosis, read the entire book, because Ginny also provides details on how she cured herself using herbs and other therapies. In fact, I'm confident that her protocol will help people with many diseases, including other autoimmune issues. This could literally be a textbook in the naturopathic medical curriculum. Its content is vast, deep, and well-researched. Although I've been involved in natural medicine for twenty years, I still benefit from periodic reminders about how to live well. This book is a strong reminder. I improved my diet and cleaning products immediately upon reading it. I thoroughly enjoyed this book, and read it again from cover-to-cover. It's one of those books every health care practitioner should read, and one that everyone would benefit from reading, and re-reading periodically.

Book Description
First published in 1988: This easy-to-read handbook provides a comprehensive review of the current knowledge on lichens. The structure of lichens and their dual nature is explained, as well as the physiology of interaction of the symbionts. The way lichens reproduce and their ecology is included, with methods for cultivating them and their isolated symbionts. Extremely useful as a text of lichenology, this handbook will benefit students of lichenology and allied fields, those interested in symbiotic associations and ecology, and teachers of biology, botany, and ecology courses.

Book Description
The available literature on freshwater fungi is limited. Over the subsequent years a considerable volume of scientific papers have appeared scattered throughout numerous journals. There is therefore no recent synthesis of the subject and this is the objective of the proposed book. Freshwater habitats are rich in fungi with some 3,000 described species, most of papers focussing on their identification, substrata they grow on and world distribution. However, these fungi play an important role in the freshwater ecosystem, and are primarily involved in the breakdown of leaf litter contributing food for detritus feeders. Our book will bring together a wide range of acclaimed mycologists to review recent developments on the biology and ecology of freshwater fungi, particularly their molecular phylogeny, biodiversity, causative diseases of freshwater amphibians, fishes and invertebrate animals, decomposition of leaf litter, stream pollution and their potential role in bioremediation.

Book Description
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.
