Bryophytes were a pivotal step in land plant evolution, and their significance in the regulation of ecosystems and the conservation of biodiversity is becoming increasingly acknowledged. This introductory textbook assumes no prior knowledge of bryophyte biology, making it ideal for advanced undergraduate and graduate students, as well as amateur botanists. The authors expertly summarise the diversity of bryophytes and outline recent advances in our understanding of their evolutionary history, their ecological roles and preferences, their distribution patterns and conservation needs. The text is highly illustrated throughout, with boxed summaries of topics of current relevance in bryophyte biology, and a glossary of technical terms.
The mosses (Bryophatea, Musci) are a diverse and widely distributed group of land plants. Mosses are attractive experimental plants because they exhibit the traditional attributes of good model systems (Le. ease of growth & maintenance, fast generation time, and amenable genetics) with the added advantage of a haploid gametophyte that allowed developmental mutants to be recovered with relative ease. In addition, mosses with the ability to tolerate extreme environmental conditions offer realistic models for the analysis of environmental stress-tolerance; particularly when compared to tracheophytes such as Arabidopsis thaliana in which these important plant phenotypes are either not clearly expressed or entirely lacking. And, in one of the most exciting developments in Plant Biology, efficient homologous recombination occurs in the moss Physcomitrella patens. The ability to perform efficient homologous recombination (Le. gene knock-outs) in P. patens is at present unique amongst all plants and represents an extremely powerful technique for the functional analysis of many plant genes. Over the past 5 years, a world-wide community of moss researchers has evolved. A highly successful "Moss" conference has been held annually (l998-Mumbai, India; 1999-Carbondale, IL, USA; 2000-Villars, Switzerland; 200l-0kazaki, Japan; 2002-Ambleside, UK; 2003-St. Louis, MO, USA) with "Moss 2004" planned to be held in Frieburg Germany. These conferences have been instrumental in the creation & development of strong collaborative ties, and the free exchange of both ideas and materials.
Considers the evolution and adaptions of arctic and antarctic floras and the role of these plants in the vegetation and in the functioning of tundra ecosystems.
This reference provides information about recent trends in bryology in parts of India, tropical rainforests and arctic regions. Bryophytes are the earliest land plants and quite fascinating in their overall diversity. All through its history, bryological study has contributed considerably to the field of plant sciences, for instance, the discovery of sex chromosomes in plants. The study of bryophytes is fundamental to our understanding of land plant evolution, and the latest progress in molecular phylogenetics and genomics have given researchers a clear depiction of land colonization of plants and subsequent terrestrial progression. Ecologically, the importance of bryophytes for the participation in biogeochemical cycles, in particular carbon cycle is now appreciated. Further, there has been an escalating interest in the conservation biology of bryophytes. The contributors have put forward holistic information regarding current research scenario of bryology in a range of environments to readers learning about research in applied bryology. The compilation of reviews presents reported findings related to various aspects of the subject, such as, conservation, diversity, tissue culture, bio-monitoring, computational bryology, molecular bryology, and species. Botanists and bryologists will receive updated information that will be valuable for their research work. The reader-friendly text is also suitable for beginners in applied plant science. Recent Advances in Botanical Science provides updated research and reviews on topics related to plant biology, genetics, taxonomy and ecology. The series is a useful resource for readers interested in applied plant science.
Bryophytes, which are important constituents of ecosystems globally and often dominate carbon and water dynamics at high latitudes and elevations, were also among the pioneers of terrestrial photosynthesis. Consequently, in addition to their present day ecological value, modern representatives of these groups contain the legacy of adaptations that led to the greening of Earth. This volume brings together experts on bryophyte photosynthesis whose research spans the genome and cell through whole plant and ecosystem function and combines that with historical perspectives on the role of algal, bryophyte and vascular plant ancestors on terrestrialization of the Earth. The eighteen well-illustrated chapters reveal unique physiological approaches to achieving carbon balance and dealing with environmental limitations and stresses that present an alternative, yet successful strategy for land plants.
The Study Of Bryophytes Is No Longer Confined To Their Morphology, Anatomy, Life-History, And Phylogenetic Considerations. In Recent Years There Has Been An Increasing Emphasis On Investigations Concerning The Ultrastructure, Reproductive Biology, Ecology, Morphogenesis, Physiology, Biochemistry And Related Aspects Of Bryophytes. These Themes Have Also Rightfully Found Their Place In The Syllabi At All Levels In Most Universities All Over The Globe. However, The Writing Of Texts In This Area Has Lagged Behind. Since The Literature Is Scattered And At Times Not Easy To Reach, There Is An Urgent Need For A Book Which Deals With The Modern Topics Of Bryology. This Volume Is Intended To Fill This Gap. The Authors Have Tried To Make The Compilation Of The Literature As Up-To-Date As Possible, And The References Cited In The Text Have Been Listed At The End Of Each Chapter For Those Interested In More Details. Most Of The Illustrations Have Been Taken From Recent Research Publications And These Have Not Previously Been Included In Any Book As Far As We Aware. Summary Charts And Tables Are Provided At All Appropriate Places.
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.
Bryophytes, a group of plants present in all terrestrial biomes of the Earth, play a significant role in ecosystems and have potential use in many life domains. They can be used in the cosmetic, pharmaceutical, and healthcare domains and can help to improve air quality, create bio-repellents and bio-pesticides, and help cure both human and animal diseases. This book discusses novel aspects of fundamental and applicative bryophyte biology.
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.
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.
