Download or read book Spores of the Pteridophyta written by Alice F. Tryon and published by Springer. This book was released on 1991 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book constitutes a unique, encyclopedic reference work that systematizes and categorizes for the first time in such comprehensive fashion all known fern spores. The dominant feature of the work are the over 350 plates of electron micrographs showing the morphological characteristics of typical representatives of each spore type. The purpose of the book is to provide a complete survey of the available data on the fine structure and composition, development, and evolu- tionary significance of different types of spore walls, which have proven resistant to fossilization throughout geological ages. The classification system developed by the authors as the result of many years of research will be a point of reference, if not "the" systematic basis, for all future publication on the subject. The book will be of great interest to all botanists and evolutionary biologists working with spores and/or ferns, but it will also be of major importance to paleobotanists, palynologists, stratigraphers, and exploration geologists, since the focus of this treatise is on spores as highly adapted and longlived reproductive forms.

Download or read book Fossil Fungi written by Thomas N Taylor and published by Academic Press. This book was released on 2014-08-14 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fungi are ubiquitous in the world and responsible for driving the evolution and governing the sustainability of ecosystems now and in the past. Fossil Fungi is the first encyclopedic book devoted exclusively to fossil fungi and their activities through geologic time. The book begins with the historical context of research on fossil fungi (paleomycology), followed by how fungi are formed and studied as fossils, and their age. The next six chapters focus on the major lineages of fungi, arranging them in phylogenetic order and placing the fossils within a systematic framework. For each fossil the age and provenance are provided. Each chapter provides a detailed introduction to the living members of the group and a discussion of the fossils that are believed to belong in this group. The extensive bibliography (~ 2700 entries) includes papers on both extant and fossil fungi. Additional chapters include lichens, fungal spores, and the interactions of fungi with plants, animals, and the geosphere. The final chapter includes a discussion of fossil bacteria and other organisms that are fungal-like in appearance, and known from the fossil record. The book includes more than 475 illustrations, almost all in color, of fossil fungi, line drawings, and portraits of people, as well as a glossary of more than 700 mycological and paleontological terms that will be useful to both biologists and geoscientists. - First book devoted to the whole spectrum of the fossil record of fungi, ranging from Proterozoic fossils to the role of fungi in rock weathering - Detailed discussion of how fossil fungi are preserved and studied - Extensive bibliography with more than 2000 entries - Where possible, fungal fossils are placed in a modern systematic context - Each chapter within the systematic treatment of fungal lineages introduced with an easy-to-understand presentation of the main characters that define extant members - Extensive glossary of more than 700 entries that define both biological, geological, and mycological terminology

Download or read book Size Limits of Very Small Microorganisms written by National Research Council and published by National Academies Press. This book was released on 1999-10-13 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: How small can a free-living organism be? On the surface, this question is straightforward-in principle, the smallest cells can be identified and measured. But understanding what factors determine this lower limit, and addressing the host of other questions that follow on from this knowledge, require a fundamental understanding of the chemistry and ecology of cellular life. The recent report of evidence for life in a martian meteorite and the prospect of searching for biological signatures in intelligently chosen samples from Mars and elsewhere bring a new immediacy to such questions. How do we recognize the morphological or chemical remnants of life in rocks deposited 4 billion years ago on another planet? Are the empirical limits on cell size identified by observation on Earth applicable to life wherever it may occur, or is minimum size a function of the particular chemistry of an individual planetary surface? These questions formed the focus of a workshop on the size limits of very small organisms, organized by the Steering .Group for the Workshop on Size Limits of Very Small Microorganisms and held on October 22 and 23, 1998. Eighteen invited panelists, representing fields ranging from cell biology and molecular genetics to paleontology and mineralogy, joined with an almost equal number of other participants in a wide-ranging exploration of minimum cell size and the challenge of interpreting micro- and nano-scale features of sedimentary rocks found on Earth or elsewhere in the solar system. This document contains the proceedings of that workshop. It includes position papers presented by the individual panelists, arranged by panel, along with a summary, for each of the four sessions, of extensive roundtable discussions that involved the panelists as well as other workshop participants.

Download or read book Sporopollenin written by J. Brooks and published by Elsevier. This book was released on 2013-09-03 with total page 731 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sporopollenin presents the proceedings of a Symposium held at the Geology Department, Imperial College, London, on September 23-25, 1970. The book discusses the functional roles of spore and pollen grain walls, the sporopollenin concept, as well as spore wall patterning. The text also describes the role played by sporopollenin in the development of pollen in Pinus banksiana; the morphological and fluorescence microscopical investigation on sporopollenin formation at Pinus sylyestris and Gasteria verrucosa; and primuline-induced fluorescence of the first exine elements and ubisch bodies in Ipomoea and Lilium. The ultrastructural and chemical studies of pollen wall development in the Epacridaceae; the implications on the nature of sporopollenin based upon pollen development; and the production of sporopollenin by the Tapetom are also considered. The book further tackles the resistance and stratification of the exine; the preservation of sporopollenin membranes under natural conditions; and a paleobiological definition of sporopollenin. The text also encompasses the aspects of sporin on the aromatization of sporin and the hydrogen density of the sporin of carboniferous lycopsids; the chemistry of sporopollenin; and some chemical and geochemical studies on sporopollenin. The petrology and geochemistry of sporinite; the application of diagenesis of sporopollenin and other comparable organic substances to hydrocarbon research; and the thermal degradation of sporopollenin and the genesis of hydrocarbons are also looked into. Botanists and microbiologists will find the book invaluable.

Download or read book Morphology, Development, and Systematic Relevance of Pollen and Spores written by Michael Hesse and published by Springer. This book was released on 2012-02-24 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Palynology, the science of fossil and recent spores/pollen grains, is of high importance, both in many pure and applied fields of the natural sciences (e.g. in botany, geology, climatology, archeology and medicine). It is not only an auxiliary science, but can certainly stand for itself. The "classical" palynology subjects, pollen morphology and systematics, are at present influenced by many modern approaches, e.g. from cell biology, analytical electron microscopy, morphometry, up to com- puter-aided-design of threedimensional reconstruction. In recent years fascinating informations have come to light, and new insights have given rise to changing scientific concepts. During the XIV International Botanical Congress, held in Berlin in 1987, a symposium was devoted to important topics of (actuo)palynology. Nine of its innovative, major contributions are presented in this volume. They cover the comparative morphology and the systematic/evolutionary significance of pollen/spores in critical taxa, aspects of pollen development (cytoskeleton), the substructure of sporopollenin, homologies between wall strata of ferns, gymnosperms and angiosperms, and important (but so far underrated) physical aspects of harmomegathy and pollen transport (fluid versus solid mechanics).
