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 The Lichens written by Vernon Ahmadijian and published by Elsevier. This book was released on 2012-12-02 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: "Lichens" by Annie Lorrain Smith Annie Lorrain Smith's textbook "Lichens" has been largely considered by biologists to be a foundational educational text on this particular area of mycology. As a leading scientist in the field at the time of writing this 1921 text, it served as the gold standard for students studying lichens for decades. Though her work has been updated due to the advances science has made in the century since its first publication, Smith's work is still highly regarded as an important part of the history of biology.

This book was released on 2012-12-06 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in Antarctica in the past two decades has fundamentally changed our perceptions of the southern continent. This volume describes typical terrestrial environments of the maritime and continental Antarctic. Life and chemical processes are restricted to small ranges of ambient temperature, availability of water and nutrients. This is reflected not only in life processes, but also in those of weathering and pedogenesis. The volume focuses on interactions between plants, animals and soils. It includes aspects of climate change, soil development and biology, as well as above- and below-ground results of interdisciplinary research projects combining data from botany, zoology, microbiology, pedology, and soil ecology.

Download or read book Lichen Physiology and Cell Biology written by D. H. Brown and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is currently impossible to grow lichens under controlled conditions in the laboratory in sufficient quantity for physiological experiments. Lichen growth is slow and conditions which might accelerate the process tend to favour either the algal or fungal partner, resulting in the breakdown of balance symbiosis. Lichen physiologists are therefore forced to use field-grown material with all the problems associated with the unknown influences of unpredictable and unreproducible climatic conditions. Study of major biochemical topics, such as the nature of the carbohydrate and nitrogenous compounds passing between the symbionts, is less influenced by climatic conditions than the intrinsic nature of the symbionts and many advances have been made in these areas. Recently, the challenge of using field-grown plant material, the physiological status of which is intimately linked to environmental conditions, has proved to be a stimulus rather than a hindrance to a number of research groups. The occurrence of lichens in extreme habitats has prompted a number of field and laboratory studies with material from such diverse localities as the cold deserts of Antarctica and the temperate rain forests of the New Zealand bush. A comparative approach, using contrasted species or habitats from a particular geographical region has yielded much information and an appreciation of the variety of physiological adaptations which may exist. The close linkage between morphology and physiology is now being directly demonstrated, as is the relevance of ultrastructural information.

Download or read book Arctic and Alpine Environments written by Jack D. Ives and published by Routledge. This book was released on 2019-10-08 with total page 1134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1974, Arctic and Alpine Environments examines, the relatively simple ecosystems of arctic and alpine lands that still occupy extensive areas little disturbed by modern technology. The book argues that there is a necessity for carefully controlled development of the resources of these regions and suggests that there is a risk of irreversible disturbance without full understanding of these regions. This book provides a detailed documentation of cold-stressed arctic and alpine terrestrial environments and systematically deals with the present and past physical environment – climate, hydrology and glaciology; biota – treeline, vegetation, vertebrate zoology, and historical biogeography; abiotic processes – geomorphological and pedological and the role of man – bioclimatology, archaeology and technological impact, including radioecology. The book will appeal to academics and students of environmental and biological science, as well as providing a significant source for conservationists’, government agencies and industrial organizations.

Download or read book Antarctic Environments and Resources written by J.D. Hansom and published by Routledge. This book was released on 2014-06-03 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antarctica is no longer a 'pole apart'. From a scientific perspective, the Antarctic ice sheet, ocean and climate systems are intimately linked with the global climate and are now seen to be of international significance for understanding climate change. From an economic perspective, the Antarctic is perceived to have great potential as a source of marine resources although the extent of speculated mineral and hydrocarbon resources is unknown. From a conservation perspective, the continent of Antarctica represents the ideal image of unspoiled wilderness. Antarctic Environments and Resources is an accessible and timely new geography of the Antarctic which examines the differing and sometimes conflicting interests in the great southern continent, the Southern Ocean and the subantarctic islands against a background of the physical and natural systems of the region and their interactions. It charts the development of human involvement in the area, focusing on the exploitation of resources from early sealing to modern fisheries, tourism and science, and it assesses the consequent impacts on the natural environment. The text also reviews the emerging framework for future environmental management developed under the Antarctic Treaty System. This is an ideal text for undergraduates studying glacial geomorphology, environmental management, polar regions and the Antarctic.
