Download or read book Asteraceae written by Kåre Bremer and published by Timber Press (OR). This book was released on 1994 with total page 772 pages. Available in PDF, EPUB and Kindle. Book excerpt: The result is the most comprehensive elucidation of the evolutionary relationships of the Asteraceae and of the groups within it, and an exhaustive classification of the family. All available information on the phylogeny of the family has here been assembled in one volume; included are more than 50 cladograms and phylogenetic trees, many of them from new and hitherto unpublished cladistic analyses. In addition to introductory chapters on cladistics, classification, morphology, and evolution, the book also includes chapters on each of the sub-families and tribes, with illustrations of morphological details, as well as descriptions of all genera. Several of these chapters were provided by Arne A. Anderberg, Per Ola Karis, Bertil Nordenstam, Johannes Lundberg, and Olof Ryding, from the Swedish Museum of Natural History in Stockholm and from the Department of Systematic Botany at Uppsala University, Sweden.

Download or read book Apomixis in Plants written by Lenn Jerling and published by Routledge. This book was released on 2017-11-22 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Apomixis in Plants presents a comprehensive review of different aspects of asexual seed formation in plants. This is important in plant research since apomixis could greatly facilitate breeding in important crops. It is also interesting theoretically because it carries problems related to genetic variation and evolution to its extreme. The book features a broad selection of topics, including a historical review of ideas and landmarks in the field; comparisons with other types of asexual reproduction in higher plants and with related phenomena in animals and related plants; a presentation of cytology and embryology of apomicts and the diversified terminology in the field; views on the genetic background of apomixis and environmental effects on its expression; and the interrelation between apomixis and other traits. Additional topics covered include classical and modern theories of sexual versus asexual reproduction; geographical and taxonomical trends in apomicts; ecological implications of apomixis, and a review of future possibilities for using apomixis in plant breeding. Apomixis in Plants is an important reference volume for researchers and students in all areas of botany, ecology, and plant breeding.

Download or read book Late Cainozoic Floras of Iceland written by Thomas Denk and published by Springer Science & Business Media. This book was released on 2011-03-28 with total page 863 pages. Available in PDF, EPUB and Kindle. Book excerpt: Being the only place in the northern North Atlantic yielding late Cainozoic terrestrial sediments rich in plant fossils, Iceland provides a unique archive for vegetation and climate development in this region. This book includes the complete plant fossil record from Iceland spanning the past 15 million years. Eleven sedimentary rock formations containing over 320 plant taxa are described. For each flora, palaeoecology and floristic affinities within the Northern Hemisphere are established. The exceptional fossil record allows a deeper understanding of the role of the “North Atlantic Land Bridge” for intercontinental plant migration and of the Gulf Stream-North Atlantic Current system for regional climatic evolution. ’Iceland sits as a “fossil trap” on one of the most interesting biogeographic exchange routes on the planet - the North Atlantic. The fossil floras of Iceland document both local vegetational response to global climate change, and more importantly, help to document the nature of biotic migration across the North Atlantic in the last 15 million years. In this state-of-the-art volume, the authors place sequential floras in their paleogeographic, paleoclimatic and geologic context, and extract a detailed history of biotic response to the dynamics of physical change.’ Bruce H. Tiffney, University of California, Santa Barbara ’This beautifully-illustrated monograph of the macro- and microfloras from the late Cenozoic of Iceland is a worthy successor to Oswald Heer’s “Flora fossilis arctica”. Its broad scope makes it a must for all scientists interested in climatic change and palaeobiogeography in the North Atlantic region. It will remain a classic for years to come.’ David K. Ferguson, University of Vienna
