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.

Concentration on renewable resources, sustainability and replacement of oil based products are driving forces to reassess the potential of natural resources including natural colorants. The growing consumer interest in purchasing “green” products, which exhibit an improved environmental profile, can be seen as the break-through force needed to reintroduce natural colorants into the modern markets. Written by scientists with specialised knowledge in the field, Handbook of Natural Colorants provides a unique source of information, summarising the present knowledge of natural colorants in depth. Supporting researchers in this emerging field of sustainable chemistry, it provides easy access to the theory and practice of natural colorants from different viewpoints, including agricultural, economic and legislative aspects. Topics covered include: History of coloration technology Present position of natural colorants Regional plant source availability Specific application techniques Chemical properties that professional dyers and chemists have to consider Agricultural sourcing of dyes with an emphasis on renewable resources Discussions on energy and material balance issues arising from the sourcing of materials Production aspects of colorants, leading on to the key applications Environmental and economic aspects Also included are the pros and cons of natural dyestuffs, presenting some promising results and evaluating the potential use of vegetable dyes as alternatives to chemical-based ones with a focus on green chemistry

Ein neuer Blick auf alte Freunde Erstaunliche Dinge geschehen im Wald: Bäume, die miteinander kommunizieren. Bäume, die ihren Nachwuchs, aber auch alte und kranke Nachbarn liebevoll umsorgen und pflegen. Bäume, die Empfindungen haben, Gefühle, ein Gedächtnis. Unglaublich? Aber wahr! – Der Förster Peter Wohlleben erzählt faszinierende Geschichten über die ungeahnten und höchst erstaunlichen Fähigkeiten der Bäume. Dazu zieht er die neuesten wissenschaftlichen Erkenntnisse ebenso heran wie seine eigenen unmittelbaren Erfahrungen mit dem Wald und schafft so eine aufregend neue Begegnung für die Leser: Wir schließen Bekanntschaft mit einem Lebewesen, das uns vertraut schien, uns aber hier erstmals in seiner ganzen Lebendigkeit vor Augen tritt. Und wir betreten eine völlig neue Welt ...
