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 Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of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.

Available in PDF, EPUB and Kindle. Book excerpt: Angiosperms are the most diversi ed plant group in the world, being represented by ca 300,000 species in about 400 families. Like all of Life, including ourselves, they have had their own history and gone through many evolutionary stages before they arrived at their current forms. The origin of Angiospermae ( owering plants) has been the subject of much dispute because this is a key event in the history of life, and has a far-reaching in uence on our understanding of relationships among seed plants as a whole as well as within the angiosperms. Until recently most of palae- otanists recognized angiosperms only from the Cretaceous and younger strata. This contradicts the results of molecular analyses. I have been working on Mesozoic fossil plants for the past two decades, during which time I have studied a number of fossil plants. Some of these fossil plants have been published as Jurassic angiosperms, and, unsurprisingly, many questions and doubts have been raised about them. These questions need to be addressed se- ously and journal papers do not provide suf cient space to compare and relate these early angiosperms. In this book these pioneer angiosperms are documented in detail, sometimes with new specimens not studied before. Also, I propose a de nition of angiosperms that could be adopted in palaeobotany. My aim is to improve clarity and objectivity of judgment about what constitutes a fossil angiosperm.

Download or read book Palaeobiology of Angiosperm Origins written by Norman F. Hughes and published by Cambridge University Press. This book was released on 1976-01-29 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolutionary origin and early history of the angiosperms (or flowering plants), which are the dominant land plants today, has remained an unsolved problem since the time of Darwin. It has been referred to since those days as an 'abominable mystery', because neither direct ancestor nor an agreed date could be determined. Mr Hughes argues that previous approaches, mostly through botanical theory, have been inadequate and misleading. He suggests that the date is about 110 million years ago (in the Cretaceous period) and there is a good chance of ancestors being found if the correct approach is adopted to the study of other fossil plants of that period. Moreover, the study of plant microfossils in the past twenty years has made feasible a fuller geological study of other fossils. When this book was first published in 1976, several reviewers saw it as a timely book on a controversial subject.

Download or read book The Origins of Angiosperms and their Biological Consequences written by Else Marie Friis and published by Cambridge University Press. This book was released on 1989-05-18 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was originally published in 1989. The dramatic radiation of the angiosperms towards the end of the Early Cretaceous initiated major changes in terrestrial ecosystems throughout the world. Dramatic changes in the flora and fauna were exemplified by the development of angiosperm-dominated plant communities and the rapid diversification of mammals, birds and insects. Written specifically for use by advanced undergraduate and graduate students, the book presents an overview of works on the origins of angiosperms and the ecological effects upon terrestrial life of their rapid radiation. It will be of particular value to students of palaeobiology and ecology, as well as to those studying evolutionary biology and systematics.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Marking the change in focus of tree genomics from single species to comparative approaches, this book covers biological, genomic, and evolutionary aspects of angiosperm trees that provide information and perspectives to support researchers broadening the focus of their research. The diversity of angiosperm trees in morphology, anatomy, physiology and biochemistry has been described and cataloged by various scientific disciplines, but the molecular, genetic, and evolutionary mechanisms underlying this diversity have only recently been explored. Excitingly, advances in genomic and sequencing technologies are ushering a new era of research broadly termed comparative genomics, which simultaneously exploits and describes the evolutionary origins and genetic regulation of traits of interest. Within tree genomics, this research is already underway, as the number of complete genome sequences available for angiosperm trees is increasing at an impressive pace and the number of species for which RNAseq data are available is rapidly expanding. Because they are extensively covered by other literature and are rapidly changing, technical and computational approaches—such as the latest sequencing technologies—are not a main focus of this book. Instead, this comprehensive volume provides a valuable, broader view of tree genomics whose relevance will outlive the particulars of current-day technical approaches. The first section of the book discusses background on the evolution and diversification of angiosperm trees, as well as offers description of the salient features and diversity of the unique physiology and wood anatomy of angiosperm trees. The second section explores the two most advanced model angiosperm tree species (poplars and eucalypts) as well as species that are soon to emerge as new models. The third section describes the structural features and evolutionary histories of angiosperm tree genomes, followed by a fourth section focusing on the genomics of traits of biological, ecological, and economic interest. In summary, this book is a timely and well-referenced foundational resource for the forest tree community looking to embrace comparative approaches for the study of angiosperm trees.
Download or read book Concepts of Biology written by Samantha Fowler and published by . This book was released on 2018-01-07 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.
