Download or read book Lichens of Antarctica and South Georgia written by D. O. Øvstedal and published by Cambridge University Press. This book was released on 2001-05-17 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Lichens to Biomonitor the Environment written by Vertika Shukla and published by Springer Science & Business Media. This book was released on 2013-08-23 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book embodies the detailed account about unique symbionts i.e. LICHENS in ecosystem monitoring. The first chapter deals with unique characteristics features of lichens which facilitate their survival in extreme climates and makes them an ideal organism for ecosystem monitoring. Biosynthesis of secondary metabolites are known to protect lichens against increasing environmental stresses therefore second chapter provides insight into various chromatographic and modern spectroscopic techniques involved in separation and characterization of lichen substances. The third chapter elaborates the criteria for selection of biomonitoring species and characters of host plant that influences lichen diversity and details about different lichen species utilized for biomonitoring. One can retrieve preliminary information about the air quality based on the lichen community structure and distribution of bioindicator species as lichen communities/indicator species provides valuable information about the natural/anthropogenic induced changes in the microclimate and land-use changes due to human activity. Therefore, for identification of species, a key to genera and species provides concise information to identify the lichen species based on their morphological and anatomical characters and chemicals present. Keys provided in Chapter 4 will help the beginners to identify some common lichen species based on the distribution in different climatic zones of India. The section also provides comprehensive information about the bioindicator communities and bioindicator species from India. Chapter 5 provides the details of factors affecting the ecosystem (natural as well as anthropogenic disturbances) and role of lichens in ecosystem monitoring in India has been discussed in detail. Chapter 6 discusses the need and utility of indicator species especially lichen biomonitoring data in sustainable forest management and conservation. The content about lichens in biomonitoring will be a valuable resource for researchers from different fields and will provide an essential reference for people interested in lichens and its role in ecosystem monitoring. The book will also hopefully popularize lichenological studies in India and will generate more active participation of lichen biomonitoring studies in management and conservation of natural resources in India.

Download or read book Alpine Biodiversity in Europe written by Laszlo Nagy and published by Springer Science & Business Media. This book was released on 2003-06-12 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United Nations Conference on the Environment and Development (UNCED), held in Rio de Janeiro in 1992, spawned a multitude of pro grammes aimed at assessing, managing and conserving the earth's biological diversity. One important issue addressed at the conference was the mountain environment. A specific feature of high mountains is the so-called alpine zone, i. e. the treeless regions at the uppermost reaches. Though covering only a very small proportion of the land surface, the alpine zone contains a rela tively large number of plants, animals, fungi and microbes which are specifi cally adapted to cold environments. This zone contributes fundamentally to the planet's biodiversity and provides many resources for mountain dwelling as well as lowland people. However, rapid and largely man-made changes are affecting mountain ecosystems, such as soil erosion, losses of habitat and genetic diversity, and climate change, all of which have to be addressed. As stated in the European Community Biodiversity Strategy, "the global scale of biodiversity reduction or losses and the interdependence of different species and ecosystems across national borders demands concerted international action". Managing biodiversity in a rational and sustainable way needs basic knowledge on its qualitative and quantitative aspects at local, regional and global scales. This is particularly true for mountains, which are distributed throughout the world and are indeed hot spots of biodiversity in absolute terms as well as relative to the surrounding lowlands.
Download or read book Lichen Bioindication of Biodiversity Air Quality and Climate written by Sarah Jovan and published by . This book was released on 2008 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lichens are highly valued ecological indicators known for their sensitivity to a wide variety of environmental stressors like air quality and climate change. This report summarizes baseline results from the U.S. Department of Agriculture, Forest Service, Forest Inventory and Analysis (FIA) Lichen Community Indicator covering the first full cycle of data collection (1998-2001, 2003) for Washington, Oregon, and California. During this period, FIA conducted 972 surveys of epiphytic macrolichen communities for monitoring both spatial and long-term temporal trends in forest health. Major research findings are presented with emphasis on lichen biodiversity as well as bioindication of air quality and climate. Considerable effort is devoted to mapping geographic patterns and defining lichen indicator species suitable for estimating air quality and climate.
Download or read book Biodiversity and Ecology of Lichens written by André Aptroot and published by . This book was released on 2009 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume on lichen biodiversity and ecology is dedicated to Harrie Sipman. It contains 29 peer-reviewed contributions by 50 authors. The emphasis is on the biodiversity and ecology of lichens in the tropics, but some papers are devoted to related areas. This volume is indispensable for active lichenologists, especially because it contains keys to several lichen genera. Full monographs are presented for the reinstated genus Herpothallon (with 29 species), the new genera Diaphorographis (with 2 species), Sipmaniella (with 1 species) and Synarthothelium (with 2 species), and the genus Placopyrenium (with 14 species and 3 varieties). Keys are furthermore given to all cryptothalline species of Lecidea, the lichenicolous genus Sphaerellothecium and the species of Cryptothecia and Stirtonia in Thailand. The genus Trypetheliopsis is resurrected for Musaespora, and all relevant combinations are made. Most papers describe various new species from all over the world, in the genera Bacidia, Buellia, Caloplaca, Chapsa, Cladonia, Cryptothecia, Diaphorographis, Gassicurtia, Herpothallon, Micarea, Phaeographis, Placocarpus, Placopyrenium, Porina, Pyrenula, Pyxine, Stirtonia, Strigula, Synarthothelium, Thelocarpon, Thelopsis, Xanthoparmelia, and Zwackhiomyces. The newly described Thelopsis is intermediate between that genus and Topelia, leading to the supposition that these genera are one continuum and should be united. Floristic papers are presented on lichens from Montenegro, Korea, Japan, Thailand, Namibia (including the description of an association), South Africa and the Seychelles and bryophytes of the Galapagos, but specimens from a multitude of other countries ranging from Iceland to Australia are cited throughout the papers. The floristic papers contain also new synonymys and combinations, partly in additional genera like Mycomicrothelia. One paper is devoted to lichens and global warming. The volume also contains three phylogenetic studies, viz. on all lichen groups with cyanobacteria, on Schistophoron and on Tylophoron, in which a systematic placement for this enigmatic genus is postulated for the first time. The volume is completed by lists of published papers and species decribed by Harrie Sipman. The volume is richly illustrated and contains many colour photographs, e.g. from all Herpothallon species and from sections through the apothecia of many Lecidea species.

Download or read book Systematics Biodiversity and Ecology of Lichens written by Ingvar Kärnefelt and published by . This book was released on 2012 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Bryophyte Ecology and Climate Change written by Zoltán Tuba and published by Cambridge University Press. This book was released on 2011-01-06 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bryophytes, especially mosses, represent a largely untapped resource for monitoring and indicating effects of climate change on the living environment. They are tied very closely to the external environment and have been likened to 'canaries in the coal mine'. Bryophyte Ecology and Climate Change is the first book to bring together a diverse array of research in bryophyte ecology, including physiology, desiccation tolerance, photosynthesis, temperature and UV responses, under the umbrella of climate change. It covers a great variety of ecosystems in which bryophytes are important, including aquatic, desert, tropical, boreal, alpine, Antarctic, and Sphagnum-dominated wetlands, and considers the effects of climate change on the distribution of common and rare species as well as the computer modeling of future changes. This book should be of particular value to individuals, libraries, and research institutions interested in global climate change.

Download or read book Recent Advances in Lichenology written by Dalip Kumar Upreti and published by Springer. This book was released on 2015-02-09 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Biology of Alpine Habitats written by Laszlo Nagy and published by Oxford University Press. This book was released on 2009-03-19 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is unique in providing a global overview of alpine (high mountain) habitats that occur above the natural (cold-limited) tree line, describing the factors that have shaped them over both ecological and evolutionary timescales. The broad geographic coverage helps synthesise common features whilst revealing differences in the world's major alpine systems from the Arctic to the Tropics. The words "barren" and "wasteland" have often been applied to describe landscapes beyond the treeline. However, a closer look reveals a large diversity of habitats, assemblages and individual taxa, largely connected to topographic diversity within individual alpine regions. The book considers habitat-forming factors (landforms, energy and climate, hydrology, soils, and vegetation) individually, as well as their composite impacts on habitat characteristics. Evolution and population processes are examined in the context of the responsiveness / resilience of alpine habitats to global change. Finally, a critical assessment of the potential impacts of climate change, atmospheric pollutants and land use is made and related to the management and conservation options available for these unique habitats.

Download or read book Ecological Regions of North America written by and published by . This book was released on 1997 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.
