Available in PDF, EPUB and Kindle. Book excerpt: This systematic treatment of the ferns and allied plants provides a modern classification of the Pteridophyta based on an assess ment of the wealth of new data published during the last few decades as well as on our own research. The accounts of the gen era include systematics, ecology, geography, spores and cytology and often other aspects of their biology. The scope of the work has involved all genera and the Old World species of those gen era represented in America. For a few American genera, that are especially complex in the Old World, it has been necessary to limit their treatment to the American representatives and this is specifically indicated in those cases. The eight American genera that do not occur in the tropics are treated in less detail. They are Camptosorus, Gymnocarpium, Matteuccia and Onoclea of North America, Arthropteris and Thyrsopteris of the Juan Fernandez Islands, Pleurosorus of southern South America, and the amphi tropical Cryptogramma. The complete generic nomenclature is included, except in a few specified cases where taxonomic complexities of the Old World elements have not been resolved. The synonyms and ac cepted names of subgeneric and sectional taxa are included only when pertinent to the generic nomenclature or to an infrageneric classification. Only the name of a publishing author is cited. There is no bibliographic purpose served by including the name of a person who was the source of, but did not validly publish, a name or epithet.
Download or read book Plants of Oceanic Islands written by Tod F. Stuessy and published by Cambridge University Press. This book was released on 2017-10-26 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bringing together results from over 30 years of research on the Juan Fernández Archipelago off the coast of Chile, this book offers comprehensive coverage of the plants of these special islands. Despite its remote setting in the southeastern Pacific Ocean, the Juan Fernández Archipelago is in many ways an ideal place to ask and attempt to answer basic questions regarding the evolution of vascular plants in an oceanic island environment. By building upon a firm taxonomic base for the flora, a new level of understanding regarding evolution, biogeography, and conservation of the plants is presented. This book is an extensive investigation of the origin and evolution of the flora of an oceanic archipelago, and it serves as a valuable resource for researchers and scholars of island biology as well as for conservation biologists worldwide.
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.

Download or read book Spores of the Pteridophyta written by Alice F. Tryon and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 659 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book constitutes a unique, encyclopedic reference work that systematizes and categorizes for the first time in such comprehensive fashion all known fern spores. The dominant feature of the work are the over 350 plates of electron micrographs showing the morphological characteristics of typical representatives of each spore type. The purpose of the book is to provide a complete survey of the available data on the fine structure and composition, development, and evolu- tionary significance of different types of spore walls, which have proven resistant to fossilization throughout geological ages. The classification system developed by the authors as the result of many years of research will be a point of reference, if not "the" systematic basis, for all future publication on the subject. The book will be of great interest to all botanists and evolutionary biologists working with spores and/or ferns, but it will also be of major importance to paleobotanists, palynologists, stratigraphers, and exploration geologists, since the focus of this treatise is on spores as highly adapted and longlived reproductive forms.
Download or read book Environmental History of Oceanic Islands written by Tod F. Stuessy and published by Springer Nature. This book was released on 2020-07-01 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Juan Fernández Archipelago is located in the Pacific Ocean west of Chile at 33° S latitude. Robinson Crusoe Island is 667 km from the continent and approximately four million years old; Alejandro Selkirk Island is an additional 181 km west and only one million years old. The natural impacts of subsidence and erosion have shaped the landscapes of these islands, resulting in progressive changes to their subtropical vegetation. The older island has undergone more substantial changes, due to both natural causes and human impacts. After the discovery of Robinson Crusoe Island in 1574, people began cutting down forests for lumber to construct boats and homes, for firewood, and to make room for pastures. Domesticated plants and animals were introduced, some of which have since become feral or invasive, causing damage to the local vegetation. The wealth of historical records on these activities provides a detailed chronicle of how human beings use their environment for survival in a new ecosystem. This book offers an excellent case study on the impacts that people can have on the resources of an oceanic island.
