Available in PDF, EPUB and Kindle. Book excerpt: It has long been the custom among those making pollen surveys to expose microscope slides coated with a suitable adhesive and examine them for the pollen grains caught. The counts of the various species are tabulated each day and at the end of the season drawn into a graph or pollen spectrum, as it is called , which gives a clear picture of the relative amounts of the different kinds of pollen which are floating in the air from day to day throughout the growing season If done in the north temperate zone such a spectrum will show the pollen of the early flowering trees, at first a trickle, as the junipers, alders and hazels flower, then a deluge as the birches, oaks and pines and many other trees cast their pollen to the air. This is generally followed by a long stream of grass pollen, fluctuating from week to week as the various species come into flower, reach their zenith, then die out giving way to succeeding species And toward the end of the summer pollens of the late flowering weeds make their appearance, nowadays in most places completely dominated by that of the ragweed. If the record is repeated the following year the spectrum will be nearly the same The succession can be counted on to repeat itself with subtle change from year to year for many years to come, unless some cataclysm changes the surrounding vegetation which contributes to the pollen spectrum, for it is always a faithful representation of the surrounding vegetation.

The book consists of contributions from internationally-known scientists from India, Australia, Malaysia, Norway, Mexico, USA, Germany, and Brazil, and shows applications around the world and in a wide variety of settings.
Download or read book Pollen Terminology written by Michael Hesse and published by Springer Science & Business Media. This book was released on 2009-01-14 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Palynology is important in basic as well as in manifold applied sciences, as e.g. biology, medicine, forensics, earth history, climatology and food production. This volume is the first fully illustrated handbook of palynological principles and glossary terms, exclusively using LM and EM micrographs of superior quality. A comprehensive General Chapter on pollen morphology, anatomy, pollen development etc. based on the present knowledge in palynology introduces the reader in the world of pollen. The glossary part comprises more than 300 widely used terms illustrated with over 1.000 high quality light and/or electron microscopic pictures to show the character range of a term. Terms are grouped by feature, e.g. ornamentation, where each term is illustrated on a separate page, definition and original citation included and where necessary, provided with a comprehensive explanatory comment. The term's use in LM, SEM or TEM and its assignment to anatomical, morphological and/or functional pollen features is indicated by icons and colour coding, respectively. This handbook is not only a valuable source for students and researchers but also for all persons interested in pollen and its aesthetic beauty.
Download or read book Paleoethnobotany written by Deborah M. Pearsall and published by Academic Press. This book was released on 2013-10-22 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the approaches and techniques of paleoethnobotany--the study of the interrelationships between human populations and the plant world through the archaeological record. Its purpose is twofold. First, it assembles in one volume the three major methods of paleoethnobotany, the analysis of macroremains, pollen analysis, and phytolith analysis, for the student or professional interested in the field. Second, it presents on paleoethnobotanist's view of the discipline: its past, present, and future, its strengths and weaknesses, and its role in modern archaeology.ï A comprehensive reference work for archaeologists and paleobotanists interested in reconstructing interrelationships between humans and plants from the archaeological recordï The first general of work theory and methods to emerge from this subdiscipline which has developed during the past twenty yearsï Makes the approaches and techniques of this field more accessible to the general anthropological and botanical audiencesï Offers archaeologists a handbook of field sampling and flotation techniques as well as an introduction to methods of analysis and interpretation in paleoethnobotany

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 Vegetation history written by B. Huntley and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 808 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of vegetation history is one of the prime objectives for vegetation scientists. In order to understand the recent composition of local floras and plant communities a second knowledge of species com position during recent millenia is essential. With the present concern over climate changes, due to human activities, an understanding of past vegeta tion distribution becomes even more important, since the correlation between climate and vegetation can often be used to predict possible impacts to crops and forests. I was very fortunate to receive the help of Drs. Webb and Huntley to compile this volume on vegetation history. They have collated an impres sive set of papers which together give an account of the vegetation history of most of the continents during the late-Tertiary and Quaternery periods. There are, however, gaps in the coverage achieved, most notably Africa, and Asia apart from Japan. The information in this book will nonetheless certainly be used widely by vegetation scientists for the regions covered in the book and much of it has relevance to the areas not explicitly described. The authors of the individual chapters have done their best to cover recent topics of interest as well as established facts. It is intended that a separate volume will be produced in the near future covering the vegetation history of Africa and Asia. I thank the editors of It fits well into the this volume for their commendable achievement.
