Available in PDF, EPUB and Kindle. Book excerpt: In February, 1974, an 'International Workshop on Membrane Transport in Plants' was held at the Nuclear Research Centre, JLiI ich, West Germany. More than two hundred and fifty people, from fourteen countries, took part in this highly successful meeting. A somewhat similar meeting took place in Liverpool, England, two years ago and it became clear there that progress in the field of membrane transport in plants was now so marked that a second, and wider, meeting in Germany was more than fully justified. The members of our pro gramme committee (U. Zimmermann, Chairman, JLilich (FRG); J. Dainty,

Available in PDF, EPUB and Kindle. Book excerpt: As plant physiology increased steadily in the latter half of the 19th century, problems of absorption and transport of water and of mineral nutrients and problems of the passage of metabolites from one cell to another were investigated, especially in Germany. JUSTUS VON LIEBIG, who was born in Darmstadt in 1803, founded agricultural chemistry and developed the techniques of mineral nutrition in agricul ture during the 70 years of his life. The discovery of plasmolysis by NAGEL! (1851), the investigation of permeability problems of artificial membranes by TRAUBE (1867) and the classical work on osmosis by PFEFFER (1877) laid the foundations for our understanding of soluble substances and osmosis in cell growth and cell mechanisms. Since living membranes were responsible for controlling both water movement and the substances in solution, "permeability" became a major topic for investigation and speculation. The problems then discussed under that heading included passive permeation by diffusion, Donnan equilibrium adjustments, active transport processes and antagonism between ions. In that era, when organelle isolation by differential centrifugation was unknown and the electron microscope had not been invented, the number of cell membranes, their thickness and their composition, were matters for conjecture. The nature of cell surface membranes was deduced with remarkable accuracy from the reactions of cells to substances in solution. In 1895, OVERTON, in U. S. A. , published the hypothesis that membranes were probably lipid in nature because of the greater penetration by substances with higher fat solubility.

Download or read book The Physiology of Characean Cells written by Mary J. Beilby and published by Springer Science & Business Media. This book was released on 2013-11-19 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the unique characean experimental system, which provides a simplified model for many aspects of the physiology, transport and electrophysiology of higher plants. The first chapter offers a thorough grounding in the morphology, taxonomy and ecology of Characeae plants. Research on characean detached cells in steady state is summarised in Chapter 2, and Chapter 3 covers characean detached cells subjected to calibrated and mostly abiotic types of stress: touch, wounding, voltage clamp to depolarised and hyperpolarised potential difference levels, osmotic and saline stress. Chapter 4 highlights cytoplasmic streaming, cell-to-cell transport, gravitropism, cell walls and the role of Characeae in phytoremediation. The book is intended for researchers and students using the characean system and will also serve as an invaluable reference resource for electrophysiologists working on higher plants.

This book was released on 2013-10-22 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intestinal Absorption of Metal Ions, Trace Elements, and Radionuclides focuses on the transport of metal ions across biological membranes. The selection first discusses fundamental considerations of ion transport across biological membranes, including passage of ions through the pores of gels or membranes; mobilities of organic and inorganic ions in water; and complexing of alkali metal ions. The text then focuses on ion transport across membranes of high ionic selectivity and transmissivity and their uses in model studies; model systems for transcellular active transport; and detection and implications of active salt transport across biological membranes. The book takes a look at the intestinal absorption of sodium, calcium, and potassium, including sodium and potassium transport in the intestines; use of radioisotopes to assess intestinal flux of calcium in humans; and calcium and structure of cell membranes. The intestinal absorption of zinc, cobalt, and strontium and absorption of copper from the gastrointestinal tract are underscored. The selection is a recommendable source of data for readers interested in the transport of metal ions across biological membranes.

Available in PDF, EPUB and Kindle. Book excerpt: TO THE SECOND EDITION When preparing the manuscript for the original edition of this book we were only partly aware of the pace at which the field of membrane transport was developing and at which new ideas as well as new techniques would be applied to it. The fact is that some of the chapters are now outdated (e. g. , the one on the molecular aspects of transport) and many others require revision in the light of new information that has appeared in the past five years. However, it is also true that we overemphasized in the first edition certain points that now appear less important and underestimated the impact of certain others that have since assumed a position among the most forcefully discussed topics of membrane research. In making amends, it was thus thought useful to include the discussion of these latter problems both in the theoretical and in the comparative sections and, on the other hand, to omit some of the less topical subjects. There was a different reason for rewriting the section on kidney and for dropping the section on mito chondria. The help of an expert nephrologist was enlisted for improving chapter 24, while it was decided that mitochondria represent a special field both conceptually (being only subcellular particles) and methodologically (more indirect estimation techniques being involved than with whole cells or tissues) and that more adequate information can be found in treatises specializing in work with mitochondria.

Available in PDF, EPUB and Kindle. Book excerpt: Winner, Wildlife Publications Award — Outstanding Book Category, The Wildlife Society, 2004 Texas Tech University President's Book Award, 2005 Shallow wetlands that occur primarily in semi-arid to arid environments, playas are keystone ecosystems in the western Great Plains of North America. Providing irreplaceable habitat for native plants and animals, including migratory birds, they are essential for the maintenance of biotic diversity throughout the region. Playas also serve to recharge the aquifer that supplies much of the water for the Plains states. At the same time, however, large-scale habitat changes have endangered playas across the Great Plains, making urgent the need to understand their ecology and implement effective conservation measures. This book provides a state-of-the-art survey of all that is currently known about Great Plains playa ecology and conservation. Loren Smith synthesizes his own extensive research with other published studies to define playas and characterize their origin, development, flora, fauna, structure, function, and diversity. He also thoroughly explores the human relationship with playas from prehistoric times, when they served as campsites for the Clovis peoples, to today's threats to playa ecosystems from agricultural activities and global climate change. A blueprint for government agencies, private conservation groups, and concerned citizens to save these unique prairie ecosystems concludes this landmark study.
