Book excerpt: The principle objective of this book is to describe a range of families of flowering plants in a sequence corresponding to current phylogenetic classification based on the most recent results of molecular systematics. The selection of families is large and comprises families of temperate European flora as well as tropical flora. They are integrated in their respective orders and keys are given to help the reader recognize them. Each family is richly illustrated, the identifying characters being shown as clearly as possible. A glossary complements the overall didactic qualities of this reference.
Download or read book The Flavonoids written by Jeffrey B. Harborne and published by Springer. This book was released on 2013-11-11 with total page 1218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flavonoids, one of the most numerous and widespread groups of natural constituents, are important to man not only because they contribute to plant colour but also because many members (e.g. coumestrol, phloridzin, rotenone) are physiologically active. Nearly two thousand substances have been described and as a group they are universally distributed among vascular plants. Although the anthocyanins have an undisputed function as plant pigments, the raison d'etre for the more widely distributed colourless flavones and flavonols still remains a mystery. It is perhaps the challenge of discovering these yet undisc10sed functions which has caused the considerable resurgence of interest in flavonoids during the last decade. This book attempts to summarize progress that has been made in the study of these constituents since the first comprehensive monograph on the chemistry of the flavonoid compounds was published, under the editorship of T. A. Geissman, in 1962. The present volume is divided into three parts. The first section (Chapters 1-4) deals with advances in chemistry, the main emphasis being on spectral techniques to take into account the re cent successful applications of NMR and mass spectral measurements to structural identifications. Recent developments in isolation techniques and in synthesis are also covered in this section. Advances in chemical knowledge of individual c1asses of flavonoid are mentioned inter aha in later chapters of the book.
Download or read book Systematics and Evolution written by David J. McLaughlin and published by Springer. This book was released on 2015-03-30 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume includes treatments of systematics and related topics for both fungi and fungus-like organisms in four eukaryotic supergroups, as well as specialized chapters on nomenclature, techniques and evolution. These organisms are of great interest to mycologists, plant pathologists and others, including those interested in the animal parasitic Microsporidia. Our knowledge of the systematics and evolution of fungi has made great strides since the first edition of this volume, largely driven by molecular phylogenetic analyses. Consensus among mycologists has led to a stable systematic treatment that has since become widely adopted and is incorporated into this second edition, along with a great deal of new information on evolution and ecology. The systematic chapters cover occurrence, distribution, economic importance, morphology and ultrastructure, development of taxonomic theory, classification, and maintenance and culture. Other chapters deal with nomenclatural changes necessitated by revisions of the International Code of Nomenclature for algae, fungi and plants, including the elimination of separate names for asexual states, as well as methods for preservation of cultures and specimens, character evolution and methods for ultrastructural study, the fungal fossil record, and the impact of whole genomes on fungal studies.
Download or read book Axioms and Principles of Plant Construction written by R. Sattler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the proceedings of a symposium which I organised for the Developmental Section of the Xlllth International Botanical Congress at Sydney, Australia on August 26, 1981. The paper by Professor T. Sachs, which was received too late for inclusion into the symposium at Sydney, was added to these proceedings because of its direct relevancy and importance. The aim of the symposium was to state in an explicit and comprehensive fashion the most basic axioms and principles of plant morphology and morphogenesis. An awareness of these axioms and principles is of paramount importance since they form. the foundations as well as the goal of structural developmental botany. Both teaching and research are predicated on them. The Introduction by the editor briefly examines the meaning of the concepts "axiom", "principle", and "plant construction". The comprehensive paper by Dr. G. Cusset, a unique historical overview, explicates 37 principles of 5 major conceptual systems and many subsystems. The extensive analysis includes a genealogy of ideas and ways of thinking of major authors ranging from philosophers and naturalists of antiquity to recent investigators of plant form and structure. The bibliography of Dr. Cusset I s paper comprises ca. 700 references. The contribution by Professor H. Mohr focusses on modern principles of morphogenesis and provides a penetrating analysis of scientific explanation in developmental biology. The universal principles (laws) described in this paper apply to all living systems, whereas the more specific principles are limited to plants or only higher plants. Professor T.

Available in PDF, EPUB and Kindle. Book excerpt: Kaplan's Principles of Plant Morphology defines the field of plant morphology, providing resources, examples, and theoretical constructs that illuminate the foundations of plant morphology and clearly outline the importance of integrating a fundamental understanding of plant morphology into modern research in plant genetics, development, and physiology. As research on developmental genetics and plant evolution emerges, an understanding of plant morphology is essential to interpret developmental and morphological data. The principles of plant morphology are being brought into studies of crop development, biodiversity, and evolution during climate change, and increasingly such researchers are turning to old texts to uncover information about historic research on plant morphology. Hence, there is great need for a modern reference and textbook that highlights past studies and provides the synthesis of data necessary to drive our future research in plant morphological and developmental evolution. Key Features Numerous illustrations demonstrating the principles of plant morphology Historical context for interpretations of more recent genetic data Firmly rooted in the principles of studying plant form and function Provides evolutionary framework without relying on evolutionary interpretations for plant form Only synthetic treatment of plant morphology on the market Related Titles Les, D.

Download or read book Phyllotaxis Models written by Jean-Paul Walch and published by John Wiley & Sons. This book was released on 2023-07-13 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The equations of phyllotaxis were discovered by Douady and Couder: these describe the inhibition "force" generated by an incipient primordium, preventing the initiation of other primordia in its vicinity: the method that was lacking was to take into account the distance of primordia to the meristem apex over the course of its development. With these parameters, our model integrates both biochemical "forces" (inhibition due to auxin) and mechanical forces (contact pressure). This powerful tool allows us to revisit many important notions of plant biology. For example, we model auxin concentrations at the plant apex, as well as the development of vegetative and reproductive meristems. We also explain why the whorls of monocots are trimerous and those of plants with quincuncial perianths are pentamerous. We design a geometric method for reconstructing inflorescences from their building blocks, i.e. floral meristems. We also show that phyllotaxic spirals are only the application of a general property of symmetry, the advantages of which have been exploited by natural selection.
Download or read book Evolutionary Theory and Processes Modern Horizons written by Eviatar Nevo and published by Springer Science & Business Media. This book was released on 2004-01-31 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolution is the most profound of human ideas integrating all natural phenomena: cosmic, biological, and cultural into a continuous universal change. This volume deals with evolutionary observations, experiments, and theories contributing to a deeper understanding of the evolutionary process, th honoring the 75 birthday of Eviatar (Eibi) Nevo. I first met Eibi in 1966 when he was a Fellow in the Museum of Comparative Zoology at Harvard University and working mostly on cricket frog vocalization and speciation in the United States. His unique discovery of pipid fossil frogs in the Israeli Early Cretaceous, central Negev, is possibly the largest world collection of ancient fossil frogs. Our acquaintance developed into mutual friendship and admiration. Since then our long-lasting friendship has included a visit to Israel, enabling me to follow Eibi's major scientific achievements, in particular, his founding of the Institute of Evolution in the University of Haifa and now the pending establishment of the International Graduate School of Evolution. The research program of Eibi Nevo, in collaboration with numerous colleagues and students in Israel and across the world, encompasses diverse perspectives of evolutionary biology and biodiversity of genes, populations, species, and ecosystems integrating modem and classical evolutionary approaches, molecular and organismal. They deal with model organisms in all forms from bacteria through plants, fungi, animals, and humans conducted over local, regional, and global scales.

Download or read book Evolution of Living Organisms written by Pierre-P. Grassé and published by Academic Press. This book was released on 2013-09-03 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolution of Living Organisms: Evidence for a New Theory of Transformation discusses traditional interpretations of evolution with a new assumption. The book presents a rational and general account of real evolutionary phenomena based on paleontology and molecular biological data. The text reviews biological evolution from the simple to the complex or progressive and regressive evolution. The author explains the appearance of types of organization from Captorhinomorphs to Pelycosaurs to the Theriodonts— from which the mammals arose. He also explains that in the evolution to mammals, the transformation of the Theriodonts concerned only the skeleton, muscles, dentition, and not the brain. He cites the case of the Perissodactyls as an example. The author also asserts that paleontology and molecular biology can explain the mechanism of evolution without even detailing the causes of orientations of lineages, of the finalities of structures, of living functions, and of cycles. But this approach will involve metaphysics. This book can be appreciated by anthropologists, researcher and scientists involved in zoology, paleontology, genetics and biochemistry.

Download or read book The Lichens written by Vernon Ahmadijian and published by Elsevier. This book was released on 2012-12-02 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lichens covers the structure and development, physiology of the intact thallus, environmental response and effects, secondary metabolic products, and symbiont interactions of lichens. This book is divided into five parts encompassing 19 chapters. It also includes appendices consist of a taxonomic scheme, methods for isolating and culturing lichen symbionts and thalli, and methods for isolating and identifying lichen substances. The first part of this book describes the original fungal cell and its development into specialized cells of which the various tissues and thalli are composed. This is followed by discussions on sexual reproduction of ascolichens and basidiolichens and on systematic criteria for the definition of taxa in different hierarchical steps. This book also explains the types of propagules produced by lichens and the submicroscopical investigations of lichens, including phycobiont and mycobionts' substructure and symbiotic relationship. The second part of this book examines the physiological aspects of lichens. It includes discussions on metal cation uptake and translocation in vascular plants and on lichens' role in rock weathering and soil formation. This part also studies photosynthetic rates and nitrogen absorption and metabolism by the intact thallus of lichens. Succeeding chapters discuss physiological and morphological responses of lichens to the most important environmental factors and the relationship of these factors to lichen distribution. Substrate preferences of lichens and their causes and implications with regard to the ecology, distribution, and taxonomy of lichens are also examined. This text also discusses lichen thalli growth, methods of measurement, and factors influencing growth. Finally, the concluding parts deal with the biosynthesis of lichen substances, secondary metabolic products, and symbiotic relations of lichens to fungi and algae. This multi-authored book is an ideal source of information for researchers, teachers, and students who wish to broaden their knowledge in the diversity of lichenology.
