Recent Advances in Lichenology by Dalip Kumar Upreti,Pradeep K. Divakar,Vertika Shukla,Rajesh Bajpai Pdf

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.

The Lichens by Vernon Ahmadijian Pdf

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.

Diversity of Lichenology by Arne Thell,M. R. D. Seaward,Tassilo Feuerer Pdf

This 100th anniversary volume of Bibliotheca Lichenologica, pays tribute to the diversity in lichenology. Multiple, cosmopolitan aspects of the research on lichens in its breadth are reflected in the large variety of subjects covered in 18 chapters by 37 authors from 13 countries. The chapters document recent developments in taxonomy, phytogenetic analyses, phylogenetic research, fl oristic studies and lichen ecology, and - again - a large number of newly described taxa, keys to the identifi cation of Usnea, and details of current analytical work. A personal review by Ingvar Kärnefelt of past and present contributors to lichenology. His biographical sketches provide a good measure of the multi-faceted nature of lichenology and of the expertise involved in its development, paying tribute to Bibliotheca Lichenologica's anniversary. The volume was carefully edited by three prominent and active members of the lichenological community, Arne Thell, University of Lund, Sweden, Mark R. D. Seaward, University of Bradford, United Kingdom, and Tassilo Feuerer, University of Hamburg, Germany.

Systematics, Biodiversity and Ecology of Lichens by Ingvar Kärnefelt,M. R. D. Seaward,Arne Thell Pdf

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.

The Lichen-Forming Fungi by D. L. Hawksworth Pdf

Lichen assocIations include some of the oldest living organisms and represent a major nutritional method adopted by one in five fungi. Major advances in our knowledge of these biologically fascinating organisms have been made in recent years and they now have a great deal to offer to teaching in colleges and universities. In addition to being examples of biotrophic systems, they merit discussion in courses on fungal phylogeny, fungal nutrition, ecology, ecophysiology, biogeography, evolution, chemo taxonomy, environmental monitoring, and algology. As all aspects of lichenology cannot be treated adequately in a book of this length, we have emphasized topics which we have found to be of particular interest to a advanced undergraduate and postgraduate biologists (or biogeographers) or those contemplating more detailed studies in particular areas. Consequently we have endeavoured to place lichen associations in the broader context of biological and biogeographical teaching. Examples are drawn from many areas of the world, including North America, but it is inevitable that European ones predominate, as lichens there are better known than in other regions. Technical terms are defined when first used, and definitions can therefore be located with the aid of the index. Lichens are not a systematic group and so are not appropriately treated in a groups-orientated programme, but are a major biological phenomenon all too commonly accorded scant attention in university courses.

Environmental Concerns and Sustainable Development by Vertika Shukla,Narendra Kumar Pdf

The current global environmental crisis is primarily the result of non-standardized parameters for environmental regulation, and is impacting e.g. clean air, safe drinking water and the quality of food, particularly in developing nations. Due to their poor/lax execution of EIA protocols, newly developing countries are preferred destinations for establishing pollution-emitting industries, which results in the degradation and depletion of their natural resources. Lack of environmental policy intervention is another major incentive to base “dirty” industries in these nations. In order to ensure sustainable development, the highest-priority issues include the monitoring and eradication of environmental problems stemming from economic development; virtually every form of economic development primarily results in the loss of forests and thus biodiversity, followed by declining air quality and the contamination of natural resources. Sustainable development ensures responsible interactions with the environment, so as to minimize the depletion or degradation of natural resources and preserve environmental quality. It involves integrated approaches to understanding the importance of environmental management systems and policy measures that lead to improved environmental performance. This book addresses the environmental concerns associated with economic development, and with approaches to attaining sustainable economic development, which include monitoring the quality of water resources, soil erosion and degradation of the natural environment.
