Download or read book Catalogue of Selected Angiosperm Pollen Grains from Palaeogene and Neogene Sediments of India written by Surya Kant Mani Tripathi and published by Springer Nature. This book was released on 2020-03-06 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the taxonomic details of selected fossil angiosperm pollen genera and species along with their affinity and occurrences in space and time. It provides information about the historical background of palynology from Palaeogene and Neogene sediments in India, general pollen morphology along with the terms commonly used in describing fossil angiosperm pollen and an overview of the Indian Tertiary sediments. A complete list of genera described in this book is given. It also includes a key for identification of Indian angiosperm genera as well as a description of selected fossil angiosperm pollen from India along with their Indian records, illustrations, locality, age and horizon from where these have been reported. In all 130 genera and 402 species have been dealt with. The names of genera and species are arranged alphabetically. The Discussion part includes a summarized account of palynofloras, their biostratigraphic application in various regions of India and their palaeogeographical and palaeoclimatic implications.
Download or read book Foundations of Ecology written by Leslie A. Real and published by University of Chicago Press. This book was released on 2012-12-20 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assembled here for the first time in one volume are forty classic papers that have laid the foundations of modern ecology. Whether by posing new problems, demonstrating important effects, or stimulating new research, these papers have made substantial contributions to an understanding of ecological processes, and they continue to influence the field today. The papers span nearly nine decades of ecological research, from 1887 on, and are organized in six sections: foundational papers, theoretical advances, synthetic statements, methodological developments, field studies, and ecological experiments. Selections range from Connell's elegant account of experiments with barnacles to Watt's encyclopedic natural history, from a visionary exposition by Grinnell of the concept of niche to a seminal essay by Hutchinson on diversity. Six original essays by contemporary ecologists and a historian of ecology place the selections in context and discuss their continued relevance to current research. This combination of classic papers and fresh commentaries makes Foundations of Ecology both a convenient reference to papers often cited today and an essential guide to the intellectual and conceptual roots of the field. Published with the Ecological Society of America.
Download or read book Diversity and Classification of Flowering Plants written by Armen Leonovich Takhtadzhi͡an and published by Columbia University Press. This book was released on 1997 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).
Download or read book The Northwest European Pollen Flora written by W. Punt and published by Elsevier. This book was released on 2003-05-20 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume should be seen as an extension to both the existing publications for pollen identification and traditional floras based on gross morphology. In the NEPF a pollen type provides the basis for a hierarchical construction around which the diversity of palynomorphs can be organised and interpreted. It is not a physical specimen in a herbarium, as is the type of a species name, but rather a published account comprising detailed descriptions and comprehensive illustration. In Volume VIII of "The Northwest European Pollen Flora" the following families are studied: Osmundaceae, Azollaceae, Salviniaceae, Droseraceae, Aizoaceae, Aristolochiaceae, Rhamnaceae, Vitaceae, Betulaceae (incl. Corylaceae), Myricaceae, Onagracea and Lythraceae.

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.
