Available in PDF, EPUB and Kindle. Book excerpt: This endeavour is aimed to be comprehensive and innovative. It covers the entire course of reading in Bryology. After a brief Introduction, there is an account of array of diversity and development of Bryophytes. In three chapters on Liverworts, Hornworts and Mosses, one can find an illustrated and concise account of all representative types. It is followed by comparative morphology. In two chapters on Gametophyte and Sporophyte are unravelled the elements of unity in diversity. Due emphasis has been given to experimental studies. In five chapters are traced the events of life cycle; Spore germination, Protonema differentiation and Gametophyte initiation, Sexuality and Sporophyte development, Regeneration, and Alternation of generations. Experimental studies – a backbone of this book – are not only interesting in a class room but informative to decipher different aspects of differentiation. Finally, there is food for thought in chapters on Cytogenetics and Evolution, and Origin and Fossil History. At the end is an extensive bibliography of old and new Literature, for further reading.

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 Ecology of Forest Floor Bryophytes in Pseudotsuga Menziesii Tsuga Heterophylla Stands of Western Oregon written by Thomas Roy Rambo and published by . This book was released on 1997 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Species richness and abundance of forest floor bryophytes, including epiphytes from incorporated litterfall, were assessed at two sites in western Oregon. Bryophyte diversity, abundance, and community composition were compared between sites, and between young forest stands ([approximately] 55 yrs.) and old-growth stands (400+ yrs.) within each site. Relationships of stand structural features to diversity and community composition were assessed by stratifying sampling between "diversity" plots placed in areas of greater structural diversity, such as hardwood openings and remnant old-growth trees, and "matrix" plots situated within the remaining more homogeneous conifer-dominated forest matrix. Bryophyte relationships to substrate and stand age were quantified using the method of Dufrene and Legendre, which combines a species' relative abundance and relative frequency to calculate that species' importance in relation to environmental variables. The resulting "indicator value" describes a species' reliability for indicating the given environmental parameter. Ninety-three bryophyte species were found. Thirty-nine were indicative of either humus, a decay class of coarse woody debris, or stand age. A suite of bryophytes indicated old-growth forest. These were mainly either epiphytes associated with older conifers or liverworts associated with coarse woody debris. Hardwood-associated epiphytes mainly indicated young stands. Richness, particularly for liverworts, was significantly higher in old-growth than young stands, and the two ages differed significantly in community composition Substrate (ground versus coarse woody debris) and overstory (conifers versus hardwoods) were most strongly correlated with variation in bryophyte community composition. Composition changed along the continuum of coarse woody debris decomposition from recently fallen trees with intact bark to forest floor humus. Relatively open hardwood-dominated diversity plots differed in composition from matrix plots. Bryophyte abundance was lower in denser stands and plots, and positively correlated with canopy gaps, percentage of hardwoods, and incident solar radiation. The generality of inferences derived from results is limited by the number of stands studied. Landscape level factors such as topography and prevailing slope and aspect may influence results between sites and ages. However, results suggest that 1) availability of light may limit bryophyte productivity in these stands, 2) bryophyte richness increases with stand continuity, 3) older conifers, hardwoods, and coarse woody debris foster habitat complexity and diversity of bryophytes, and 4) diversity of forest floor bryophytes will be enhanced when a full range of coarse woody debris decay classes is present. Implementation of strategies to protect these biological legacies when thinning managed stands is consistent with an ecosystem approach to forest management.

Book excerpt: This book will enrich the readers theoretical knowledge about the fundamental aspects of bryology. There is a great significance of bryophytes in land plant evolution, water retention, prevention of soil erosion, nutrient cycling, nitrogen fixation and pollution monitoring. Considering this, the authors found it necessary to provide a basic guideline to the students to study the bryoflora. The present manual for bryophytes will provide practical guidelines for collection and recording of bryophytes, methodologies for studying it's morphology, morphometry and internal structure, modern approach to bryophytes systematics and characterization of genera, taxonomic importance of spore ornamentation as revealed by the Scanning Electron Microscopy, significance of bryophyte conservation and basic methods of in vitro study.

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 Bryophyte Ecology written by A. Smith and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been an increasing interest in bryophyte ecology over the past 100 or so years, initially of a phytosociological nature but, additionally, in recent years, of an experimental nature as well. Early studies of bryophyte communities have led to detailed investigations into the relationships between the plants and their environment. Ecological papers, the large number of which is evidenced by the length of the bibliographies in the subsequent chapters, have appeared in numerous journals. Yet, apart from review chapters, by H. Gams and P. W. Richards in Manual of Bryology, edited b:; H. Verdoorn in 1932 and chapters in E. V. Watson's Structure and Life of Bryophytes, Prem Puri's Bryophytes - A Broad Perspective and D. H. S. Richardson's The Biology of Mosses, published in 1972,1973 and 1981 respectively, no general accounts of bryophyte ecology have been published. Although the Bryophyta is a relatively small division of plants, with between 14000 and 21000 species the interest that they have aroused is out of all proportion to the size either of the plants or of the division. It is evident, however, that despite their relative insigni ficance they play an important ecological role, especially in extreme environments and, in the case of bryophytes in tropical cloud forests and of Sphagnum, may even be a dominant factor in the ecology of the area concerned.

Available in PDF, EPUB and Kindle. Book excerpt: This richly illustrated text/reference, originally printed in 1985, provides a comprehensive introduction to the structure, evolution and interrelationships of the bryophytes. Leading bryologist W. B. Schofield gives a broad, international view of bryology that goes beyond a basic understanding of structure to present the bryophytes as a vital group of living plants. After a solid foundation in the morphology of mosses, liverworts and hornworts separate chapters, organized to allow easy comparison of the evolutionary lines, offer definitive information on the biology of the organisms. Topics covered in detail include cytology, genetics, chemistry, ecology, physiology, geography and the history of the discipline. Emphasizing the biologic significance of the bryophytes, the author uses an abundance of elegant original illustrations to show the structure, diversity and the natural beauty of the bryophytes. There is also an extensive glossary of bryologic terminology. W. B. Schofield is Professor Emeritus at the University of British Columbia in Vancouver. He is a former president of the American Bryological and Lichenological Society.
