Book Synopsis The Historical Ecology Handbook by : Dave Egan
Download or read book The Historical Ecology Handbook written by Dave Egan and published by Island Press. This book was released on 2005-08-12 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fundamental aspect of the work of ecosystem restoration is to rediscover the past and bring it into the present-to determine what needs to be restored, why it was lost, and how best to make it live again. This handbook makes essential connections between past and future ecosystems, bringing together leading experts to offer a much-needed introduction to the field of historical ecology and its practical application by on-the-ground restorationists. - from publisher description.
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.

Book Synopsis Neogene and Quaternary Quantitative Palynostratigraphy and Paleoclimatology from Sections in Yukon and Adjacent Northwest Territories and Alaska by : J. M. White

White and published by . This book was released on 1999 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study provides a framework biostratigraphy for pollen and spores in the Neogene and Quaternary of Yukon and adjacent Northwest Territories & Alaska. This biozonation is useful for correlating continental rocks with rocks on the northern continental margin, including the petroliferous Beaufort-Mackenzie Basin. This framework biozonation achieves an absolute chronology based on the study of many continental sections where ages are determined by independent and absolute measures. The study assembles the biozonation from seven sections and one borehole, and the palynological spectra from 163 samples from these sections were grouped & averaged to produce 21 composite spectra that depict the long-term pattern of vegetation change ranging from Early Miocene to late Quaternary. Pollen and spores are grouped and summed by environmental tolerances and physiognomy of the modern families & genera of plants to which they are related. Using these groups, pollen and spore ratios are drawn to track environmental parameters (temperature, forest canopy cover, and paludification) of the study sites. Biostratigraphic and paleoecological patterns are explained in terms of known changes in the global climate and the climatic effects of regional tectonics. Six assemblage zones and five subzones are proposed to describe the palynological succession.
