Download or read book The Dawn Angiosperms written by Xin Wang and published by Springer. This book was released on 2017-08-02 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the controversial and conflicting hypotheses on the origin of angiosperms, which was generally assumed to be restricted to the Cretaceous and later ages. Since publishing the first edition of “The Dawn of Angiosperms” in 2010, several important advances have been made in this field of science, namely 1) the discovery of new fossil angiosperms from the Jurassic; 2) European researchers discovering angiosperm-like pollen from the Triassic; and most importantly 3) the discovery of a perfect flower from the Jurassic. All of these findings are at odds with the currently widely accepted evolutionary theories, and thus call upon us to critically reassess botanical theory. Accordingly, the new edition of this book not only includes more new fossil taxa, but also documents them in greater detail and corrects many commonly held misconceptions. In so doing, it makes related studies and teaching on the early history of angiosperms more realistic, concrete, and tangible, providing concrete fossil evidence as the basis for future research, and helping to distinguish the most accurate botanical hypotheses.

Second Semester students of Botany as per Common Minimum Syllabus prescribed for all Uttarakhand State Universities and Colleges under the recommended National Education Policy 2020. This textbook comprehensively covers the theoretical and practical aspect of the paper Pteridophytes, Gymnosperms and Angiosperms. The theory part of the text introduces the students to develop an understanding of morphology, anatomy and reproduction of Pteridophytes, Gymnosperms and Angiosperms. It also discusses the origin of angiosperms along with their phylogeny and classification in details. Furthermore, taxonomy of plant families has been discussed in systematic manner. Practical part provides a strong conceptual understanding of the subject, it also helps in developing scientific outlook of the student.
Download or read book Mesozoic Biological Events and Ecosystems in East Asia written by S-C. Chang and published by Geological Society of London. This book was released on 2022-08-11 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mesozoic Biological Events and Ecosystems in East Asia covers a wide range of topics, encompassing palaeoenvironments, palaeoecosystems and important vertebrate, invertebrate and plant fossils, some found in amber with excellent preservation of delicate morphological features. Fifty-three authors from a number of different disciplines – geochronology, palaeontology, stratigraphy, sedimentology, tectonics and geochemistry – contribute to the 18 articles in the volume. Well-preserved fossils and rocks continue to be found from marine and terrestrial sediments across East Asia. Over some years, the palaeontological and geological evidence discovered from this region has significantly improved our understanding of Mesozoic environments. In discussing feathered dinosaurs, primitive birds, early mammals, diverse insects, amber inclusions, the oldest-known flowers and research utilizing new, advanced methods, this volume explores Earth’s history in even greater detail. What other exciting discoveries are waiting to be unveiled in the future?
Download or read book Botany Taxonomy Of Angiosperms Biosystem written by Dr. Vatsala Tomar and published by AG PUBLISHING HOUSE (AGPH Books). This book was released on 2023-01-30 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for all levels of botanists and students taking a local flora course. For the reason that the botany is a larger subject, the book's scope is limited to angiosperms and plant bio-systems. It is intended to provide sufficient information to enable an understanding of plant taxonomy, comprehension of various contemporary classification systems, comprehension of fundamental principles of plant nomenclature, and appreciation of the mechanics of plant identification, including the preparation and preservation of herbarium specimens. Taxonomy is a difficult topic. It is, nevertheless, founded on knowledge and comprehension of plant morphology and anatomy, cytology, genetics, paleontology, and plant geography. This book is meant to let non-taxonomists utilize a handbook or flora that accounts for the plants in any place. A reader, on the other hand, would find this book highly useful in learning topics such as taxonomic hierarchy and Linnaeus classification. The process of plant nomenclature, herbarium preparation and maintenance are also included. This not only focus on biological processes but, also the standardizing authority such as ICBN, are explored in detail, and the book is presented in such a way that understanding the ideas in the material requires little effort.
Download or read book Evolution of Reproductive Organs in Land Plants written by Xin Wang and published by Frontiers Media SA. This book was released on 2018-04-06 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The great diversity of land plants (especially angiosperms) is mainly reflected in the diversity of various reproductive organs of plants. However, despite long time intensive investigations, there are still uncertainties and sometimes misunderstandings over the nature and evolution of reproductive organs in land plants. With the new advances made in various fields of botany (especially at molecular level), there is increasing light shed on some aspects of flowers (reproductive organs of angiosperms). In this ebook, we collect 15 papers reporting new understanding on plant reproductive organs. These works range from morphology and anatomy to molecular regulatory networks underlying traditional observations. We understand this single book cannot reach our goal, but we do hope that this book can contribute to or initiate some efforts leading to the final solution of some problems concerning the homology and evolution of reproductive organs in plants.
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.
Download or read book Flowers in Amber written by George Poinar and published by Springer Nature. This book was released on 2022-08-12 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: While much attention has been given to animal life in amber, the remains of a variety of plants, including angiosperm flowers, also exist in fossilized resin. Presented here is a pictorial synopsis of 94 flowers that occur in four major amber deposits around the world. These deposits are from Burma (Myanmar), the Baltic area, the Dominican Republic and Mexico, and range in age from the mid-Cretaceous to the mid-Tertiary. The basic features of these flowers are presented and their relationship with existing plant lineages discussed. This work will be of interest to amber enthusiasts, plant taxonomists, plant morphologists, plant ecologists, plant evolutionists and plant paleontologists.
