Book excerpt: Plant Biosystematics is a compendium of papers from a symposium titled "Plant Biosystematics: Forty Years Later" held in Montreal in July 1983. This collection reviews the current field of biosystematics, particularly the evolution of natural biota, and how plant biosystematics can contribute to the welfare of humans. One paper reviews biosystematics, compares new approaches, and discusses the latest trend in comparative, molecular evolution of genes. One author discusses the cytology and biosystematics concerning the discontinuities and genetic independence occurring in the evolutionary process. Another author discusses chromosome pairing in species and hybrids that includes models of chromosome pairing in diploids. The text also describes chromosome banding and biosystematics, as well as the problems of chromosome banding that should be addressed to in future research. With estimates of the number of species being threatened with extinction numbering around 20,000 one paper address the issue of conservation and biosystematics. The author suggests that more biological information should be published to avoid duplication of effort, and possibly drive scientists to have their views more widely felt. Agriculturists, botanists, conservationists, environmentalists, and researchers in the field of botany, conservation, and plant genealogy will find this book valuable.

Available in PDF, EPUB and Kindle. Book excerpt: Evolution is the central theme of all biology. Researcarcch in the many branches of evolutionary study continues to flourish. This book, based on a symposium of the Linnean Society, discusses the diversity in currentevolutionary research. It approaches the subject ambitiously and from several angles, bringing ttogether eminent authors from a variety of disciplines paleontologists traditionally with a macroevolutionary bias, neontologists concentrating on microevolutionary processes, and those studying the very essence ofsses and those studying the very essence of evolution the process of speciation in living organisms. Evolutionary Patterns and Processes will appeal to a broad spectrum of professional biologistsworking in such fields as paleontology, population biology, and evolutionary genetics. Biologists will enjoy chapters by Stephen J. Gould, discovering in the much earlier work of Hugo de Vries parallels with his ideas on punctuational evolution; Guy Bush,considering why there are so many small animals; Peter Sheldon, examining detailed fossil trilobite sequences for evidence of microevolutionary processes and considering models of speciation; as well as others dealing with cytological, ecological, and behavioral processes leading to the evolution of new species.

Download or read book Biosystematics of Triticeae written by Chi Yen and published by Springer Nature. This book was released on 2022-08-13 with total page 725 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book review and rearrange the research data of Triticeae published over hundreds of years, applying a modern scientific approach. Triticeae is an important tribe in the grass family (Peaceae). It includes the major cereal crops, such as wheat, barley and rye, in addition to many valuable forage crops found in different genera, such as Elymus, Agropyron, Pasthyrostachys, and Leymus. The knowledge of appropriate Triticeae taxonomy and biosystematics will serve as genetic breeding of wheat, barley, rye and forage grass. The authors attempted to remain the truth and remove the false for deriving a more natural biosystematics of Triticeae. This book covers taxonomy, cytogenetics, and molecular phylogeny. It summarizes the biosystematics of Triticeae with comprehensive and updated data. This book is divided into five volumes (Volumes 1- 5), and includes 30 genera, 2 subgenera, 464 species, 9 subspecies, and 186 varieties in Triticeae. Volume 5 introduces nine perennial genera in Triticeae: Campeiostachys, Elymus, Pascopyrum, Lophopyrum, Trichopyrum, Hordelymus, Festucopsis, Peridictyon, and Psammopyrum. Elymus (StH), Campeiostachys (StYH), Lophopyrum (E), and Trichopyrum (ESt)are polymorphic genus. They show similar morphological characters, and it is difficult to distinguish them based merely on morphological variation. Pascopyrum (StHNsXm), Hordelymus (XoXr), Festucopsis (L), Peridictyon (Xp), and Psammopyrum (EL) are small genera, mostly monotypic genera. This book can serve as highly qualified, valuable, and convenient handbooks for audiences who are interested in Triticeae. This book also includes many illustrations, in addition to the description, to help the audience understand, morphological features of the concerned taxa, which makes the explanation more precise and obvious. It is a useful tool to understand the relationship among species in Triticeae.

This book was released on 1993 with total page 821 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flora of North America Volume 7 will be the eighth of 19 volumes on dicotyledons to be published in the Flora of North America North of Mexico series. It treats 923 species classified among 125 genera in 11 families; the larger families covered in Volume 7 include Brassicaceae (Mustard family), Cleomaceae (Spiderflower family), and Salicaceae (Willow family). The endemic family Limnanthaceae with eight species classified in two genera (Floerkea and Limnanthes) is also included in the volume. Each genus has representative species illustrated with a line drawing that, in combination with keys and descriptions, will facilitate identifications of these groups of plants. Some of the genera treated in this volume with the most species in the flora area include: Boechera, Cardamine, Draba, Lepidium, Physaria, and Streptanthus (Brassicaceae) with 109, 39, 121, 42, 88, and 35 species, respectively; plus Salix and Populus (Salicaceae) with 113 and 8 species, respectively. Three families are represented in the flora each with a single introduced species: Caricaceae (Papaya family), Moringaceae (Drumstick tree family), and Tropaeolaceae (Nasturtium family).

This book was released on 2009-09-28 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume includes thirteen research articles focused primarily on Canadian Coleoptera. Several taxonomic and biodiversity studies examine groups within the Staphylinidae, Cerambycidae, Gyrinidae, and Haliplidae, describing new species, presenting keys to identification, mapping distributions, and reporting new provincial and national records. Other studies direct their attention to saproxylic beetles as indicators of forest disturbance, and to the beetle fauna of Rhode Island and the larger zoogeographic utility of distributional checklists. An introductory essay discusses a variety of challenges to biodiversity and biosystematics research worldwide. The contents of present volume represent stepping-stones of biodiversity research ? a discipline vital to the future of life on the planet. The book is addressed to coleopterists, taxonomists, ecologists, biogeographers and conservationists.
