Download or read book Guide to Standard Floras of the World written by David G. Frodin and published by Cambridge University Press. This book was released on 2001-06-14 with total page 1136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.

Book excerpt: Most people have memories of playing on well-manicured lawns or running across the flat green surface of a local park, but we often don’t think of grasses as something we consume. Indeed, grasses include four species—wheat, rice, maize, and sugar—that provide sixty percent of human calorie intake, and we become more and more dependent on these as the world’s population increases. In this book, Stephen Harris explains the history of our relationship with these vital plants from the end of the last Ice Age to the present day. Combining biology, sociology, and cultural history, Grasses explores how these staple crops bear the mark of human influence more visibly than any other plant and how we, in turn, are motivated to protect green space such as public parks. Harris describes this symbiotic connection against the background of climate change, contending that humans must find a way to balance their need for grass as food, as living space, and potentially even as fuel. Providing an impressive exploration of the profound impact these plants have on our survival and our pleasure, this well-illustrated book is a must have for gardeners, foodies, and environmentalists.

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.
