Available in PDF, EPUB and Kindle. Book excerpt: This open access book offers a fully illustrated compendium of glossary terms and basic principles in the field of palynology, making it an indispensable tool for all palynologists. It is a revised and extended edition of “Pollen Terminology. An illustrated handbook,” published in 2009. This second edition, titled “Illustrated Pollen Terminology” shares additional insights into new and stunning aspects of palynology. In this context, the general chapters have been critically revised, expanded and restructured. The chapter “Misinterpretations in Palynology” has been extended with new research data and additional ambiguous terms, e.g., polyads vs. massulae; the chapter “Methods in Palynology” has been extensively enhanced with illustrated protocols showing the majority of the methods and techniques used when studying recent and fossil pollen with LM, SEM and TEM. Moreover, additional information about the description and publication of pollen data is provided in the chapter “How to Describe and Illustrate Pollen Grains.” Various other parts of the general chapters have now been updated and/or extended with more comprehensive textual passages and new illustrations. The chapter “Illustrated Pollen Terms” now features new and more appropriate examples of each term, including additional LM micrographs. Where necessary, the entries for selected pollen terms have been refined by rewording or adding definitions, illustrations, and new micrographs. Lastly, new terms are included, such as “suprasculpture” and the prefix “nano-“ for ornamentation features. The chapter “Illustrated Pollen Terms” is the main part of this book and comprises more than 300 widely used terms illustrated with over 1,000 high-quality images. It provides a detailed survey of the manifold ornamentation and structures of pollen, and offers essential insights into their stunning beauty.

Download or read book Seed Biology written by T.T. Kozlowski and published by Elsevier. This book was released on 2012-12-02 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seed Biology, Volume I: Importance, Development, and Germination is a part of a three-volume treatise, which aims to bring together a large body of important information on seed biology. Organized into six chapters, this book begins with a discussion on the importance and characteristics of seeds. Separate chapters follow that discuss the development of gymnosperm and angiosperm seeds, as well as the anatomical mechanisms of seed dispersal. Other chapters focus on the morphogenetic events involved in the germination and the scientific basis for the concept of physiological predetermination or seedling vigor, including the potential application of this concept in agriculture, forestry, and management of natural resources. This work will be useful to various groups of research biologists and teachers, including plant anatomists, pathologists, and physiologists as well as agronomists, biochemists, ecologists, entomologists, foresters, and horticulturists.

Available in PDF, EPUB and Kindle. Book excerpt: "What caused the extinction of so many animals at or near the end of the Pleistocene? Was it overkill by human hunters, the result of a major climatic change or was it just a part of some massive evolutionary turnover? Questions such as these have plagued scientists for over one hundred years and are still being heatedly debated today. Quaternary Extinctions presents the latest and most comprehensive examination of these questions." —Geological Magazine "May be regarded as a kind of standard encyclopedia for Pleistocene vertebrate paleontology for years to come." —American Scientist "Should be read by paleobiologists, biologists, wildlife managers, ecologists, archeologists, and anyone concerned about the ongoing extinction of plants and animals." —Science "Uncommonly readable and varied for watchers of paleontology and the rise of humankind." —Scientific American "Represents a quantum leap in our knowledge of Pleistocene and Holocene palaeobiology. . . . Many volumes on our bookshelves are destined to gather dust rather than attention. But not this one." —Nature "Two strong impressions prevail when first looking into this epic compendium. One is the judicious balance of views that range over the whole continuum between monocausal, cultural, or environmental explanations. The second is that both the data base and theoretical sophistication of the protagonists in the debate have improved by a quantum leap since 1967." —American Anthropologist

Available in PDF, EPUB and Kindle. Book excerpt: This encyclopedia offers access to the diversity of ferns and seed plants, the most important groups of green land plants. Available information of general and systematic relevance is synthesized at the level of families. Evidence from virtually all disciplines important to modern taxonomy makes the work a most valuable source of reference not only for taxonomists, but for all who are interested in the various aspects of plant diversity. A revised classification includes a complete inventory of genera along with their diagnostic features, keys for identification, and references to the literature. The first volume deals with pteridophytes and gymnosperms.
