Download or read book Spores of the Pteridophyta written by Alice F. Tryon and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 659 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 Ice Age Southern Andes written by C.J. Heusser and published by Elsevier. This book was released on 2003-11-12 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Southern Andes, stretching from the subtropics to the subantarctic, are ideally located for palaeoenvironmental research. Over the broad and continuous latitudinal extent of the cordillera (-24˚), vegetation is adjusted to climatic gradients and atmospheric circulation patterns.Opposed to the prevailing Southern Westerlies, the Southern Andes are positioned to receive the brunt of the winds, while biota are set to record the shifting of incoming storm systems over time. Sequential, latitudinally-placed, sedimentary deposits containing microfossils and macroremains, as archives of past vegetation and climate, make possible the detection of equatorward and poleward displacement of plant communities and, as a consequence, changes in climatic controls. No terrestrial setting in the Southern Hemisphere is so unique for palaeoenvironmental reconstruction during and since the last ice age. Twenty radiocarbon-dated fossil pollen and spore records chosen to place emphasis on the last ice age include high-resolution, submillennial data sets that also cover the Holocene, thus providing contrast between present interglacial and past glacial ages. From a refined data base, the records constitute the foundation for interpreting factors responsible for vegetation change over >50,000 14C years, glacial-interglacial migration and refugial patterns for a diversity of taxa, and the extent of intrahemispheric and polar hemispheric synchroneity versus asynchroneity.

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 Palynology and Vegetation History written by Valentí Rull and published by Frontiers Media SA. This book was released on 2019-01-11 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Research Topic commemorates the centenary of the first quantitative pollen diagram by Lennart von Post, the founder of paleoecological palynology. The main aim is to provide a thorough view of the use of palynology in aspects such as the reconstruction of Quaternary vegetation and environmental changes, the role of natural and anthropogenic drivers in the development of the Quaternary vegetation, the shaping of present-day ecological and biogeographical patterns, the potential application of this knowledge in biodiversity conservation and landscape restoration and the development of new methods of pollen analysis and data management. The Research Topic is subdivided into four main conceptual parts, namely (1) modern analog studies; (2) land cover estimates from pollen data; (3) vegetation dynamics reconstructions from Europe, North and South America, Africa and Oceania; and (4) large-scale reviews and meta-analyses. Hopefully, this Research Topic will serve to appraise the state of the art of modern palynology and highlight the usefulness of this discipline in long-term ecological research.

Download or read book Plant Taxonomy written by Tod F. Stuessy and published by Columbia University Press. This book was released on 2009-01-01 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of plant taxonomy has transformed rapidly over the past fifteen years, especially with regard to improvements in cladistic analysis and the use of new molecular data. The second edition of this popular resource reflects these far-reaching and dramatic developments with more than 3,000 new references and many new figures. Synthesizing current research and trends, Plant Taxonomy now provides the most up-to-date overview in relation to monographic, biodiversity, and evolutionary studies, and continues to be an essential resource for students and scholars. This text is divided into two parts: Part 1 explains the principles of taxonomy, including the importance of systematics, characters, concepts of categories, and different approaches to biological classification. Part 2 outlines the different types of data used in plant taxonomic studies with suggestions on their efficacy and modes of presentation and evaluation. This section also lists the equipment and financial resources required for gathering each type of data. References throughout the book illuminate the historical development of taxonomic terminology and philosophy while citations offer further study. Plant Taxonomy is also a personal story of what it means to be a practicing taxonomist and to view these activities within a meaningful conceptual framework. Tod F. Stuessy recalls the progression of his own work and shares his belief that the most creative taxonomy is done by those who have a strong conceptual grasp of their own research.

Download or read book Southern Hemisphere Paleo and Neoclimates written by Peter Smolka and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate models show that climate change is not a uniform process. Areas of increased temperature are situated near areas of decreased temperature, areas with increased precipitation adjoin areas of drought. This is one of the reasons why climate change is so difficult to detect. Any parameter must be considered and tested locally or regionally and not on an average globally. This book gives an overview of current research methods and results in the different fields of climate research including modelling. In addition, it contains a hemisphere-wide stratigraphic data base with about 80000 species. All paleoclimatic data as well as a state-of-the-art atmospheric circulation model in a PC version are included. So both research and graduate teaching are supported with high-end software running on affordable computers, also in those countries that have no access to Cray super computers. Thus, this book will be of interest to all researchers and scientists in the field of climatology.
