Progress And Problems In Lichenology At The Turn Of The Millenium

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.

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.

Metals and Metalloids in Soil-Plant-Water Systems: Phytophysiology and Remediation Techniques examines the impact of metal/metalloid contamination on the plant lifecycle, along with microbes present in soil. Highlighting uptake and translocation, the book also examines antioxidant, photosynthesis and growth characteristics of plants grown in metal contaminated soil. Beginning with an introduction to different sources of soil and water pollution, chapters assess the environmental cytotoxicity pollution impact on plants, as well as how the generation of reactive oxygen and nitrogen species in plant tissues is affected. The book also discusses various soil remediation methodologies, including the potential applications of metal oxidizing microbes and nanomaterials. This is an essential resource for researchers and students interested in plant physiology, soil science, environmental science and agriculture. Provides a comprehensive overview of metal and metalloids speciation, fractionation, bioavailability and transfer to plants Analyzes properties of plants grown with excess metals/metalloids in soils Highlights applications of biochar and other biostimulants for sustainable metal/metalloid remediation

Tropical mycology is attracting increasing interest, as the key role of fungi in tropical ecosystems and as pathogens becomes appreciated. This book describes the ecology, biology, economic dimensions and systematics of tropical Micromycetes and is the second of two complementary volumes (Volume 1 covers Macromycetes) developed from papers given at the British Mycological Society's symposium held in Liverpool in April 2000.

The integration of science with art is a complex process of analysis and the knowledge and understanding of the need to save and protect works of art as well as preserve and restore cultural heritage. This is generally provoked by the living necessity, profoundly human, to leave our inheritance to new generations, as intact as is possible, the testimonies of the past.The issues approached interfere with artistic criticism, for example, biological and physico-chemical analyses, and intelligent mathematical modeling systems such as Marker-less Augmented Reality, 3D Reconstruction, intelligent combinations of digital image analysis functions to recognize and estimate the possible evolution of color and shape to help experts make the best decisions about authenticating and preserving-restoring art objects.Advanced technical devices such as digital databases and other tools and materials can allow for the eradication of offenses such as false art and falsification.
