Download or read book Illustrated Moss Flora of Antarctica written by Ryszard Ochyra and published by Cambridge University Press. This book was released on 2008-11-13 with total page 711 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mosses are a major component of the vegetation in ice-free coastal regions of Antarctica. They play an important role in the colonisation of ice-free terrain, accumulation of organic matter, release of organic exudates, and also provide a food and habitat resource for invertebrates. They serve as model organisms for physiological experiments designed to elucidate problems of plant cold tolerance and survival mechanisms and for monitoring biological responses to climate change. This Flora provides the first comprehensive description, with keys, of all known species and varieties of moss in the Antarctic biome. It has involved microscopic examination of around 10,000 specimens from Antarctica and, for comparison, from other continents. All species are illustrated by detailed line drawings, alongside information about their reproductive status, ecology, and distribution. This is an invaluable resource for bryologists worldwide, as well as to Antarctic botanists and other terrestrial biologists.
Download or read book Mosses Liverworts and Hornworts written by IUCN/SSC Bryophyte Specialist Group and published by World Conservation Union. This book was released on 2000-01-01 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bryophytes are of great importance in their ecosystems and for human well-being. They stabilize soil crust through colonization of bare grounds and rocks; they are essential in nutrient recycling, biomass production, and carbon fixing; they control water through an effective retention mechanism; and they have economic value as peat for fuel, horticulture, oil absorption, and as sources of a wide variety of chemical compounds. Bryophytes have long been used for medicinal purposes and provide a food source for reindeer, geese, ducks, sheep, musk-ox, lemmings, and other rodents. Threats include deforestation, cultivation of forests, reclamation of land, urbanization, roads, dam-building, mining, drainage of wetlands and over-grazing. This plan reviews the situation worldwide and proposes a variety of initiatives. It is aimed at those who work with and care about nature conservation, including governmental and non-governmental organizations as well as politicians and the general interested public.
Download or read book Chemical Constituents of Bryophytes written by Yoshinori Asakawa and published by Springer Science & Business Media. This book was released on 2012-11-13 with total page 811 pages. Available in PDF, EPUB and Kindle. Book excerpt: For some 50 years, Professor Asakawa and his group have focused their research on the chemical constituents of bryophytes and have found that these plants contain large numbers of secondary metabolites, such as terpenoids, acetogenins, and aromatic compounds representative of many new skeletons, which exhibit interesting biological activities. Individual terpenoids, when found as constituents of both a bryophyte and a higher plant, tend to occur in different enantiomeric forms. Professor Asakawa has covered the literature on bryophytes in two earlier volumes of Progress in the Chemistry of Organic Natural Products, namely, Volumes 42 (1982) and 65 (1995). Since the publication of the latter volume, a great deal of new information has appeared on bryophytes. One example is that known sex pheromones of algae have been discovered in two liverworts, indicating that some members of the latter taxonomic group might originate from brown algae. From information provided in this volume, it is suggested that two orders of the Marchantiophyta should be combined.
Download or read book Handbook of Alien Species in Europe written by Delivering Alien Invasive Species and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions by alien (non-native) species are widely recognized as a significant component of human-caused global environmental change and the second most important cause of biodiversity decline. Alien species threaten many European ecosystems and have serious environmental, economic and health impacts. The DAISIE (Delivering Alien Invasive Species Inventories for Europe) project has now brought together all available information on alien species in Europe (terrestrial, aquatic and marine) and from all taxa (fungi, plants, animals). Thus for the first time, an overview and assessment of biological invasions in the Pan-European region is finally possible. The Handbook of Alien Species in Europe summarises the major findings of this groundbreaking research and addresses the invasion trends, pathways, and both economic as well as ecological impact for eight major taxonomic groups. Approximately 11.000 alien species recorded in Europe are listed, and fact sheets for 100 of the most invasive alien species are included, each with a distribution map and colour illustration. The book is complemented by a regularly updated internet database providing free additional information. With its highly interdisciplinary approach, DAISIE and its Handbook will be the basis for future scientific investigations as well as management and control of alien invasive species in Europe.
Download or read book Plant and Human Health Volume 1 written by Munir Ozturk and published by Springer. This book was released on 2018-10-02 with total page 805 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early anthropological evidence for plant use as medicine is 60,000 years old as reported from the Neanderthal grave in Iraq. The importance of plants as medicine is further supported by archeological evidence from Asia and the Middle East. Today, around 1.4 billion people in South Asia alone have no access to modern health care, and rely instead on traditional medicine to alleviate various symptoms. On a global basis, approximately 50 to 80 thousand plant species are used either natively or as pharmaceutical derivatives for life-threatening conditions that include diabetes, hypertension and cancers. As the demand for plant-based medicine rises, there is an unmet need to investigate the quality, safety and efficacy of these herbals by the “scientific methods”. Current research on drug discovery from medicinal plants involves a multifaceted approach combining botanical, phytochemical, analytical, and molecular techniques. For instance, high throughput robotic screens have been developed by industry; it is now possible to carry out 50,000 tests per day in the search for compounds, which act on a key enzyme or a subset of receptors. This and other bioassays thus offer hope that one may eventually identify compounds for treating a variety of diseases or conditions. However, drug development from natural products is not without its problems. Frequent challenges encountered include the procurement of raw materials, the selection and implementation of appropriate high-throughput bioassays, and the scaling-up of preparative procedures. Research scientists should therefore arm themselves with the right tools and knowledge in order to harness the vast potentials of plant-based therapeutics. The main objective of Plant and Human Health is to serve as a comprehensive guide for this endeavor. Volume 1 highlights how humans from specific areas or cultures use indigenous plants. Despite technological developments, herbal drugs still occupy a preferential place in a majority of the population in the third world and have slowly taken roots as alternative medicine in the West. The integration of modern science with traditional uses of herbal drugs is important for our understanding of this ethnobotanical relationship. Volume 2 deals with the phytochemical and molecular characterization of herbal medicine. Specifically, it focuess on the secondary metabolic compounds, which afford protection against diseases. Lastly, Volume 3 discusses the physiological mechanisms by which the active ingredients of medicinal plants serve to improve human health. Together this three-volume collection intends to bridge the gap for herbalists, traditional and modern medical practitioners, and students and researchers in botany and horticulture.

Available in PDF, EPUB and Kindle. Book excerpt: How has California’s landscape changed? What did now-familiar places look like during prior centuries? What can the past teach us about designing future landscapes? The Napa Valley Historical Ecology Atlas explores these questions by taking readers on a dazzling visual tour of Napa Valley from the early 1800s onward—a forgotten land of brilliant wildflower fields, lush wetlands, and grand oak savannas. Robin Grossinger weaves together rarely-seen historical maps, travelers’s accounts, photographs, and paintings to reconstruct early Napa Valley and document its physical transformation over the past two centuries. The Atlas provides a fascinating new perspective on this iconic landscape, showing the natural heritage that has enabled the agricultural success of the region today. The innovative research of Grossinger and his historical ecology team allows us to visualize the past in unprecedented detail, improving our understanding of the living landscapes we inhabit and suggesting strategies to increase their health and resilience in the future.

Book excerpt: A long-awaited addition to the botany titles in the highly-regarded Collins New Naturalist series. This edition is exclusive to newnaturalists.com Mosses and liverworts - known as bryophytes - are a group of about 24,000 fairly low-growing plants which have no roots to speak of. Nor do they have flowers, but breed instead by spores. Both are commonly found in damp places, like ditches and beside streams. This authoritative guide explains their ecological importance, how they can act as environmental indicators and their general biology. With full-colour illustrations throughout, it covers: * distribution patterns and dispersal mechanisms * their relation with climate * historical uses for mosses * habitats and emmunities This is a branch of botany which has always relied heavily on amateur involvement, and the authors explain what amateurs can do today to increase our knowledge about these essential plants.
