O.L. LANGE, P.S. NOBEL, C.B. OSMOND, and H. ZIEGLER Growth, development and reproductive success of individual plants depend on the interaction, within tolerance limits, of the factors in the physical, chemical and biological environment. The first two volumes of this series addressed fea tures of the physical environment (Vol. 12A) and the special responses of land plants as they relate to water use and carbon dioxide assimilation (Vol. 12B). In this volume we consider specific aspects of the chemical and biological envi ronment, and whereas the previous volumes were primarily concerned with the atmospheric interactions, our emphasis here shifts very much to the soil. This complex medium for plant growth was briefly reviewed in Chapter 17, Volume 12A. Since it is difficult to determine the precise physical and chemical interactions in the soil, it is even more difficult to determine the important biological interactions among organisms. Nevertheless there is growing aware ness of the significance of these interactions and their effects on physiological processes in the individual plant.
In the spring of 1969 a small meeting was convened at the CSIRO Riverina Laboratory, Deniliquin, New South Wales, to discuss the biology of the genus Atriplex, a group of plants considered by those who attended to be of profound importance both in relation to range management in the region and as a tool in physiological research. The brief report of this meeting (Jones, 1970) now serves as a marker for the subsequent remarkable increase in research on this genus, and served then to interest the editors of the Ecological Studies Series in the present volume. This was an exciting time in plant physiology, particularly in the areas of ion absorption and photosynthesis, and unknowingly several laboratories were engaged in parallel studies of these processes using the genus Atriplex. It was also a time at which it seemed that numerical methods in plant ecology could be used to delineate significant processes in arid shrubland ecosystems. Nevertheless, to presume to illustrate and integrate plant physiology and ecology using examples from a single genus was to presume much. The deficiencies which became increasingly apparent during the preparation of the present book were responsible for much new research described in these pages.
Physiological Processes Limiting Plant Productivity presents the proceedings of the Thirtieth University of Nottingham Easter School in Agricultural Science held at Sutton Bonington in England on April 2-5, 1979. Contributors focus on physiological processes limiting plant growth and development in the context of agricultural productivity. Emphasis is placed on the fundamental mechanisms that underlie crop production and their control. This text is comprised of 20 chapters; the first of which discusses the genetics of crop physiology in relation to agricultural production. The range of problems that plant physiologists must address is considered, followed by an assessment of what is happening in crop physiology. A number of chapters are devoted to the utilization of light by crop plants, plant nutrition, water relations, and the effects of an adaptation to unfavorable conditions including those imposed by air pollution. The reader is also introduced to the influence of photoperiodism on crop production; gas exchange in water-stressed plants; and the use of water, solar energy, and fossil fuels in crop production. This book will be of interest to agriculturists, plant breeders, and researchers working in relevant aspects of plant biochemistry, physiology, and genetics.
O. L. LANGE, P. S. NOBEL, C. B. OSMOND, and H. ZIEGLER In the last volume of the series 'Physiological Plant Ecology' we have asked contributors to address the bases of ecosystem processes in terms of key plant physiological properties. It has often been suggested that it is not profitable to attempt analysis of complex living systems in terms of the properties of component individuals or populations, i. e. , the whole is more than the sum of its parts. Nevertheless, assessments of ecological research over the last century show that other approaches are seldom more helpful. Although it is possible to describe complex systems of living organisms in holistic terms, the most useful descriptions are found in terms of the birth, growth and death of individ uals. This allows analysis of performance of the parts of the whole considering their synergistic and antagonistic interrelationships and is the basis for a synthe sis which elucidates the specific properties of a system. Thus it seems that the description of ecosystem processes is inevitably anchored in physiological under standing. If enquiry into complex living systems is to remain a scientific exercise, it must retain tangible links with physiology. Of course, as was emphasized in Vol. 12A, not all of our physiological understanding is required to explore ecosystem processes. For pragmatic purposes, the whole may be adequantely represented as a good deal less than the sum of its parts.
The present book has been especially designed and written as per the BBA Course (Paper No. 302: Business Policy & Strategy) of Guru Gobind Singh Indraprastha University, Delhi.
Gives chapter outline to indicate the topics covered in each chapter. Provides diagrams and tables to illustrate the text. Includes examples from Indian organisations. Incorporates chapter-end summary for quick recapitulation. Gives test questions culled from MBA, M.Com and BBA examinations Includes case studies at the end of every chapter. This textbook is designed for the students of MBA and M.Com. Besides, it will also be useful to the students of MHROD, MIB and MBE. Students of postgraduate diploma in global business operations, chartered accountancy and BBA will also find this book useful.
A practical guide to the protection and management of ecosystems against invasions by non-indigenous plant species. The authors seek to offer an accessible account of the subject and how to protect natural habitats. The majority of countries suffer from invasive plants and there are case studies from North America, Europe, Australia, South and South East Asia and the Pacific and Atlantic islands. There is also a list of invasive species, with their countries of origin and regions of introduction.
In this book, first published in 1983, three independent scientists examine the results of research and development into the environmental aspects of hazardous wastes management. Within a legislative framework, the limits of our scientific knowledge are carefully defined and the ways in which this knowledge is extrapolated and applied are examined. Significant areas of uncertainty are identified and the authors have not been afraid to draw attention to the fallibility of certain interpretations. Landfill science, leachate characteristics, pollutant attenuation and toxicity measurement are reviewed. Alternative technologies such as chemical treatment and incineration are compared. Risk assessment, cost implications and public acceptance are examined. It provides an objective assessment of the scientific and practical issues involved and constitutes a valuable source book for all concerned with hazardous wastes management, planning and regulatory control, pollution prevention and environmental protection.
Shaping Science and Industry touches on Australia's intellectual, political and economic life. It provides an account of the rapid growth of CSIR (to become CSIRO) during World War II. The contributions of many outstanding personalities are described such as Sir George Julius, Sir Charles Martin, Hedley Marston, DF Martyn, AEV Richardson, Sir David Rivett, Ian Clunies Ross and FWG White.This book recounts the major effort to introduce and adapt new technologies as part of the war effort. Informative and non-technical accounts are given of some breakthroughs in agricultural research such as the eradication of prickly pear.
Marcus Van Buren's ghostly family has been a thorn in his backside since the day he was born. Now he's paying someone to get rid of them. Inexperienced ghostbuster Daisy Malone should be ecstatic the ultra-wealthy tabloid darling, Marcus Van Buren, is paying her big bucks to conduct a sham of an investigation. The windfall will bail her family out of financial ruin. According to Marcus, all she has to do is tell the truth and sign a document swearing the old family home, Laguna Vista, is 100% ghost-free. Unfortunately, Daisy knows otherwise.
