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.

Foliicolous lichens are one of the most abundant epiphytes in tropical rainforests and one of the few groups of organisms that characterize these forests. Tropical rainforests are increasingly affected by anthropogenic disturbance resulting in forest destruction and degradation. However, not much is known on the effects of anthropogenic disturbance on the diversity of foliicolous lichens. Understanding such effects is crucial for the development of appropriate measures for the conservation of such organisms. In this study, foliicolous lichens diversity was investigated in three tropical rainforests in East Africa. Godere Forest in Southwest Ethiopia is a transitional rainforest with a mixture of Afromontane and Guineo-Congolian species. The forest is secondary and has been affected by shifting cultivation, semi-forest coffee management and commercial coffee plantation. Budongo Forest in West Uganda is a Guineo-Congolian rainforest consisting of primary and secondary forests. Kakamega Forest in western Kenya is a transitional rainforest with a mixture of Guineo-Congolian and Afromontane species. The forest is a mosaic of near-primary forest, secondary forests of different seral stages, grasslands, plantations, and natural glades.

This is a timely volume in view of the considerable interest currently shown in the preservation of our cultural heritage, and the extensive and growing literature on the subject. Unfortunately, the latter is to be found in a wide variety of published sources, some aimed at a very specific readership and therefore not all that accessible to those who need this resource. The present volume draws together a spectrum of biodeterioration work from across the world to provide an overview of the materials examined and the methodologies employed to elucidate the nature of the problems, as well as an extensive and current bibliographical resource on lichen biodeterioration. Biodeterioration of historical and culturally important stone substrata is a complex problem to be addressed. Easy, risk-free solutions are simply not available to be dealt with by other than a wide range of expertise. Successful resolution of this issue will inevitably require a multidisciplinary effort, where biologists work in close cooperation with ecologists, geologists, geochemists, crystallographers, cultural property conservators, archaeologists, anthropologists, and historians in order to recommend the most effective management scheme. The advantage of this approach is obvious: multidisciplinary management teams with good leadership can ask more appropriate questions while developing much more thoughtful and informed decisions.

Peatlands form important landscape elements in many parts of the world and play significant roles for biodiversity and global carbon balance. This new edition has been fully revised and updated, documenting the latest advances in areas such as microbial processes and relations between biological processes and hydrology. As well as thoroughly referencing the latest research, the authors expose a rich older literature where an immense repository of natural history has accumulated. The Biology of Peatlands starts with an overview of the main peatland types (marsh, swamp, fen, and bog), before examining the entire range of biota present (microbes, invertebrates, plants, and vertebrates), together with their specific adaptations to peatland habitats. Detailed coverage is devoted to the genus Sphagnum, the most important functional plant group in northern peatlands, although tropical and southern hemisphere peatlands are also covered. Throughout the book the interactions between organisms and environmental conditions (especially wetness, availability of oxygen, and pH) are emphasized, with chapters on the physical and chemical characteristics of peat, the role of peat as an archive of past vegetation and climate, and peatland succession and development. Several other key factors and processes are then examined, including hydrology and nutrient cycling. The fascinating peatland landforms in different parts of the world are described, together with theories on how they have developed. Human interactions with peatlands are considered in terms of management, conservation, and restoration. A final chapter, new to this edition, focuses on the role of peatlands as sources or sinks for the greenhouse gases carbon dioxide and methane, and the influences of climate change on peatlands. This timely and accessible text is suitable for students and researchers of peatland ecology, as well as providing an authoritative overview for professional ecologists and conservation biologists.

Salt is an essential requirement of life. Already from ancient times (e. g. , see the books of the Bible) its importance in human life has been known. For example, salt symbolizes destruction (as in Sodom and Gomorra), but on the other hand it has been an ingredient of every sacrifice during the Holy Temple periods. Microbial life in concentrated salt solutions has fascinated scientists since its discovery. Recently there have been several international meetings and books devoted entirely to halophiles. This book includes the proceedings of the “Halophiles 2004” conference held in Ljubljana, Slovenia, in September 2004 (www. u- lj. si/~bfbhaloph/index. html). This meeting was attended by 120 participants from 25 countries. The editors have selected presentations given at the meeting for this volume, and have also invited a number of contributions from experts who had not been present in Ljubljana. This book complements “Halophilic Microorganisms”, edited by A. Ventosa and published by Springer-Verlag (2004), “Halophilic Microorganism and their Environments” by A. Oren (2002), published by Kluwer Academic Publishers as volume 5 of “Cellular Origins, Life in Extreme Habitats and Astrobiology” (COLE), and “Microbiology and Biogeochemistry of Hypersaline Environments” edited by A. Oren, and published by CRC Press, Boca Raton (1999). Salt-loving (halophilic) microorganisms grow in salt solutions above seawater salinity (~3. 5% salt) up to saturation ranges (i. e. , around 35% salt). High concentrations of salt occur in natural environments (e. g.

Bill Bryson describes himself as a reluctant traveller, but even when he stays safely at home he can't contain his curiosity about the world around him. A Short History of Nearly Everything is his quest to understand everything that has happened from the Big Bang to the rise of civilization - how we got from there, being nothing at all, to here, being us. Bill Bryson's challenge is to take subjects that normally bore the pants off most of us, like geology, chemistry and particle physics, and see if there isn't some way to render them comprehensible to people who have never thought they could be interested in science. The ultimate eye-opening journey through time and space, A Short History of Nearly Everything is the biggest-selling popular science book of the 21st century, and reveals the world in a way most of us have never seen it before.

Antarctica's severe climate and restricted area of ice-free habitats limit the biodiversity and biota of its terrestrial ecosystems. Throughout much of this wilderness, lichens are the predominant visible life form, yet relatively few descriptive accounts of Antarctic lichens have been published. Research on these enigmatic organisms is increasing rapidly and there is a growing need for a comprehensive guide to the identification of Antarctic lichen-forming fungi. This volume provides the first modern detailed compilation of their taxonomy, ecology, distribution and relevant published literature. As such, it represents a major contribution to global lichen taxonomy and biogeography. The systematic accounts provide sufficient descriptive information to allow specialists to identify taxa to species level, and are structured so that even non-specialists can use them to identify specimens to at least the generic level.

Fungi are ubiquitous in the world and responsible for driving the evolution and governing the sustainability of ecosystems now and in the past. Fossil Fungi is the first encyclopedic book devoted exclusively to fossil fungi and their activities through geologic time. The book begins with the historical context of research on fossil fungi (paleomycology), followed by how fungi are formed and studied as fossils, and their age. The next six chapters focus on the major lineages of fungi, arranging them in phylogenetic order and placing the fossils within a systematic framework. For each fossil the age and provenance are provided. Each chapter provides a detailed introduction to the living members of the group and a discussion of the fossils that are believed to belong in this group. The extensive bibliography (~ 2700 entries) includes papers on both extant and fossil fungi. Additional chapters include lichens, fungal spores, and the interactions of fungi with plants, animals, and the geosphere. The final chapter includes a discussion of fossil bacteria and other organisms that are fungal-like in appearance, and known from the fossil record. The book includes more than 475 illustrations, almost all in color, of fossil fungi, line drawings, and portraits of people, as well as a glossary of more than 700 mycological and paleontological terms that will be useful to both biologists and geoscientists. First book devoted to the whole spectrum of the fossil record of fungi, ranging from Proterozoic fossils to the role of fungi in rock weathering Detailed discussion of how fossil fungi are preserved and studied Extensive bibliography with more than 2000 entries Where possible, fungal fossils are placed in a modern systematic context Each chapter within the systematic treatment of fungal lineages introduced with an easy-to-understand presentation of the main characters that define extant members Extensive glossary of more than 700 entries that define both biological, geological, and mycological terminology
