This book was released on 2018-01-24 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although they are relative latecomers on the evolutionary scene, having emerged only 135?170 million years ago, angiosperms—or flowering plants—are the most diverse and species-rich group of seed-producing land plants, comprising more than 15,000 genera and over 350,000 species. Not only are they a model group for studying the patterns and processes of evolutionary diversification, they also play major roles in our economy, diet, and courtship rituals, producing our fruits, legumes, and grains, not to mention the flowers in our Valentine’s bouquets. They are also crucial ecologically, dominating most terrestrial and some aquatic landscapes. This fully revised edition of Phylogeny and Evolution of the Angiosperms provides an up-to-date, comprehensive overview of the evolution of and relationships among these vital plants. Incorporating molecular phylogenetics with morphological, chemical, developmental, and paleobotanical data, as well as presenting a more detailed account of early angiosperm fossils and important fossil information for each evolutionary branch of the angiosperms, the new edition integrates fossil evidence into a robust phylogenetic framework. Featuring a wealth of new color images, this highly synthetic work further reevaluates long-held evolutionary hypotheses related to flowering plants and will be an essential reference for botanists, plant systematists, and evolutionary biologists alike.

Book excerpt: "The book strikes a balance between classical fundamental information and the recent developments in plant systematics. Special attention has been devoted to the information on botanical nomenclature, identification and phylogeny of angiosperms with numerous relevant examples and detailed explanation of the important nomenclatural problems. An attempt has been made to present a continuity between orthodox and contemporary identification methods by working on a common example. The methods of identification using computers have been further explored to help better online identification. The chapter on cladistic methods has been totally revised, and molecular systematics discussed in considerable detail."--Jacket.

Download or read book The Tree written by Colin Tudge and published by Crown. This book was released on 2007-10-23 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: A blend of history, science, philosophy, and environmentalism, The Tree is an engaging and elegant look at the life of the tree and what modern research tells us about their future. There are redwoods in California that were ancient by the time Columbus first landed, and pines still alive that germinated around the time humans invented writing. There are Douglas firs as tall as skyscrapers, and a banyan tree in Calcutta as big as a football field. From the tallest to the smallest, trees inspire wonder in all of us, and in The Tree, Colin Tudge travels around the world—throughout the United States, the Costa Rican rain forest, Panama and Brazil, India, New Zealand, China, and most of Europe—bringing to life stories and facts about the trees around us: how they grow old, how they eat and reproduce, how they talk to one another (and they do), and why they came to exist in the first place. He considers the pitfalls of being tall; the things that trees produce, from nuts and rubber to wood; and even the complicated debt that we as humans owe them. Tudge takes us to the Amazon in flood, when the water is deep enough to submerge the forest entirely and fish feed on fruit while river dolphins race through the canopy. He explains the “memory” of a tree: how those that have been shaken by wind grow thicker and sturdier, while those attacked by pests grow smaller leaves the following year; and reveals how it is that the same trees found in the United States are also native to China (but not Europe). From tiny saplings to centuries-old redwoods and desert palms, from the backyards of the American heartland to the rain forests of the Amazon and the bamboo forests, Colin Tudge takes the reader on a journey through history and illuminates our ever-present but often ignored companions.

Download or read book Early Flowers and Angiosperm Evolution written by Else Marie Friis and published by Cambridge University Press. This book was released on 2011-08-18 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent discovery of diverse fossil flowers and floral organs in Cretaceous strata has revealed astonishing details about the structural and systematic diversity of early angiosperms. Exploring the rich fossil record that has accumulated over the last three decades, this is a unique study of the evolutionary history of flowering plants from their earliest phases in obscurity to their dominance in modern vegetation. The discussion provides comprehensive biological and geological background information, before moving on to summarise the fossil record in detail. Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of the pattern of angiosperm evolution through time. Synthesising palaeobotanical data with information from living plants, this unique book explores the latest research in the field, highlighting connections with phylogenetic systematics, structure and the biology of extant angiosperms.

Download or read book The Timetree of Life written by S. Blair Hedges and published by OUP Oxford. This book was released on 2009-04-23 with total page 1237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolutionary history of life includes two primary components: phylogeny and timescale. Phylogeny refers to the branching order (relationships) of species or other taxa within a group and is crucial for understanding the inheritance of traits and for erecting classifications. However, a timescale is equally important because it provides a way to compare phylogeny directly with the evolution of other organisms and with planetary history such as geology, climate, extraterrestrialimpacts, and other features.The Timetree of Life is the first reference book to synthesize the wealth of information relating to the temporal component of phylogenetic trees. In the past, biologists have relied exclusively upon the fossil record to infer an evolutionary timescale. However, recent revolutionary advances in molecular biology have made it possible to not only estimate the relationships of many groups of organisms, but also to estimate their times of divergence with molecular clocks. The routineestimation and utilization of these so-called 'time-trees' could add exciting new dimensions to biology including enhanced opportunities to integrate large molecular data sets with fossil and biogeographic evidence (and thereby foster greater communication between molecular and traditional systematists). Theycould help estimate not only ancestral character states but also evolutionary rates in numerous categories of organismal phenotype; establish more reliable associations between causal historical processes and biological outcomes; develop a universally standardized scheme for biological classifications; and generally promote novel avenues of thought in many arenas of comparative evolutionary biology.This authoritative reference work brings together, for the first time, experts on all major groups of organisms to assemble a timetree of life. The result is a comprehensive resource on evolutionary history which will be an indispensable reference for scientists, educators, and students in the life sciences, earth sciences, and molecular biology. For each major group of organism, a representative is illustrated and a timetree of families and higher taxonomic groups is shown. Basic aspects ofthe evolutionary history of the group, the fossil record, and competing hypotheses of relationships are discussed. Details of the divergence times are presented for each node in the timetree, and primary literature references are included. The book is complemented by an online database(www.timetree.net) which allows researchers to both deposit and retrieve data.

Download or read book Flowering Plants written by K. Kubitzki and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original suggestion to organize a symposium about the classi fication and evolution of the Flowering Plants was made at, the International Botanical Congress at Leningrad in 1975, and the idea was so well accepted by several colleagues that plans for such a symposium quickly took shape. An organizing committee consisting of Professor H. MERXMULLER, Miinchen, Professor V. H. HEYWOOD, Reading, and Professor K. KUBITZKI, Hamburg, was set up. The conference took place on 7-12 September 197tl in the Institut fiir Allgemeine Botanik of the University of Hamburg under the auspices of the International Association for Plant Taxonomy and was at tended by 80 participants from 14 countries. There have been several meetings in recent years which have dealt with the origin and evolution of the Flowering Plants so that it might be questioned whether yet another symposium dealing with more or less the same subject were really "justified. As the reader will see from the contents of the book, this symposium differed from similar ones held recently in two respects: 1. Emphasis was given to methodological aspects of the classification of higher taxa, and 2. much classificatory and evolutionary evidence relating to the higher taxa of Flowering Plants was presented.

Download or read book Aquatic Dicotyledons of North America written by Donald H. Les and published by CRC Press. This book was released on 2017-09-01 with total page 3174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic Dicotyledons of North America: Ecology, Life History, and Systematics brings together a wealth of information on the natural history, ecology, and systematics of North American aquatic plants. Most books on aquatic plants have a taxonomic focus and are intended primarily for identification. Instead, this book provides a comprehensive overview of the biology of major aquatic species by compiling information from numerous sources that lie scattered among the primary literature, herbarium databases, and other reference materials. Included dicotyledon species are those having an obligate (OBL) wetland status, a designation used in the USACE National Wetland Plant List. Recent phylogenetic analyses are incorporated and rationale is provided for interpreting this information with respect to species relationships. This diverse assemblage of information will be useful to a wide range of interests including academic researchers, wildlife managers, students, and virtually anyone interested in the natural history of aquatic and wetland plants. Although focusing specifically on North America, the cosmopolitan distribution of many aquatic plants should make this an attractive text to people working virtually anywhere outside of the region as well. This book is an essential resource for assisting with wetland delineation.

Download or read book Plant Systematics written by G Singh and published by CRC Press. This book was released on 2016-04-19 with total page 796 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of the present edition has been to further consolidate the information on the principles of plant systematic, include detailed discussion on all major systems of classification, and significantly, also include discussion on the selected families of vascular plants, without sacrificing the discussion on basic principles. The families included for discussion are largely those which have wide representation, as also those that are less known but significant in evaluating the phylogeny of angiosperms. The discussion of the families also has a considerable focus on their phylogenetic relationships, as evidenced by recent cladistic studies, with liberal citation of molecular data. Several additional families have been included for detailed discussion in the present volume.

Download or read book Diversity and Classification of Flowering Plants written by Armen Leonovich Takhtadzhi͡an and published by Columbia University Press. This book was released on 1997 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).

Download or read book The Flowering Plants Handbook written by James W. Byng and published by Plant Gateway Ltd.. This book was released on 2014-10-16 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: This plant book aims to help identify flowering plants to genus and family level anywhere in the world. In 2014 there were very few available works which were both comprehensive and up-to-date for all the flowering plants families and genera of the world. The Flowering Plants Handbook is an easy to use identification guide to the worlds flowering plants designed for both specialists and non-specialists and from beginner to expert. The book contains descriptions of all currently recognised flowering plant families, morphological notes for 6656 genera (all current genera for 398/413 families) and over 3000 images and illustrations. Flowering plants can be identified using the book to family and much of the world's generic diversity in four 'easy' steps. Some plants will be identified correctly quickly, whilst others may require some retracing of steps and take a little more time. The advantage of this book is that it helps the user learn about the classification system and plant diversity during the identification process. This work was compiled and developed using the living, library and herbarium collections at the University of Aberdeen, Royal Botanic Gardens, Edinburgh and Royal Botanic Gardens, Kew.
