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 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.

This book was released on 1997-08-28 with total page 912 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of Antarctic communities can provide a valuable step forward in investigating the control of community development, the utilization of habitats and the interaction among species in both species rich and species poor communities. This book contains chapters characterizing the present approaches to both aquatic and terrestrial communities in the Antarctic. From biodiversity to trophic flows, from ecophysiological strategies to the impacts of environmental change and the effects of human disturbance, this volume provides an up to the minute overview of community studies in an area covering ten percent of the Earth's surface.

Available in PDF, EPUB and Kindle. Book excerpt: Antarctic Ecosystems comprises 55 papers presented at the Fifth Symposium on Antarctic Biology held under the auspices of the Scientific Committee on Antarctic Research (SCAR) in Hobart, Australia, 29 August - 3 September, 1988. Both short- and long-term changes in ecosystems and community structures caused by natural and human factors were discussed to help understand the ecological processes taking place in a changing environment. The variability of ecological factors must be known for the development of realistic monitoring strategies and sound conservation practices.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 10. The existence of insects, mites, and their relatives on the antarctic continent is of great interest to many. These terrestrial arthropods may be said to be the dominant land animals in the absence of land vertebrates and many major groups of invertebrates. They are important in the simple food cycles which involve most segments of the land flora and microorganisms, and they play a part in soil formation. Thus a knowledge of their ecology is essential to the understanding of various biotic balances and processes. That several species live in the area of 85°S latitude in the face of harsh climatic factors is of great concern to the ecologist and the physiologist—therin lie many unanswered questions for future research.

Available in PDF, EPUB and Kindle. Book excerpt: Understand the properties and applications of one of the world’s most ubiquitous flora Lichen is a single entity comprising two or more organisms—most typically algae and fungus—in a symbiotic relationship. It is one of the planet’s most abundant categories of flora, with over 25,000 known species across all regions of the globe. Lichens’ status as a rich source of bioactive metabolites and phytochemicals, as well as their potential as bio-indicators, has given them an increasingly prominent role in modern research into medicine, cosmetics, food, and more. Chemistry, Biology and Pharmacology of Lichen provides a comprehensive overview of these bountiful flora and their properties. It provides not only in-depth analysis of lichen physiology and ecology, but also a thorough survey of their modern and growing applications. It provides all the tools readers need to domesticate lichen and bring their properties to bear on some of humanity’s most intractable scientific problems. Chemistry, Biology and Pharmacology of Lichen readers will also find: Applications of lichen in fields ranging from food to cosmetics to nanoscience and beyond Detailed discussion of topics including lichen as habitats for other organisms, lichens as anticancer drugs, antimicrobial properties of lichen, and many more Detailed discussion on key bioactive compounds from lichens Chemistry, Biology and Pharmacology of Lichen is ideal for scientists and researchers in ethnobotany, pharmacology, chemistry, and biology, as well as teachers and students with an interest in biologically important lichens.
