Book excerpt: Inadvertent alterations of the earth's atmosphere by man's activities are now of regional and even global proportion. Increasing concern has been focused in the last decade on consequences of acid rain, carbon dioxide enrichment of the atmosphere and reduction of ozone in the upper atmosphere. The latter two problems are of truly global scale. This book focuses on the atmospheric ozone reduction problem and the potential consequences for plant life. unlike carbon dioxide enrichment, reduction of the total atmospheric ozone column has not yet taken place to a noticeable degree -- it is a problem of the future. The processes leading to ozone reduction involve time periods on the scale of decades. However, by the same token, if society finds ozone reduction to be unacceptable it will take even longer for the process to be reversed. Thus, anticipation of the consequences of ozone reduction is of obvious importance. Speculation of the possibility of ozone reduction first appeared in the early 1970's and was focused on the consequences of the injection of large quantities of nitrogen oxides into the upper atmosphere by supersonic aircraft flying at high altitudes. Other sources of nitrogen oxides originating from the earth's surface were also considered. With further refinement, the concerns of nitrogen oxide pollution of the upper atmosphere were diminished since the quantities likely to be involved were insufficient to cause a serious threat to the ozone layer.

This book was released on 2013-03-09 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: From microbial to plant ecosystems, this book examines how changes in UV radiation, caused by anthropogenic ozone depletion, as well as changes in radiation levels throughout the evolution of life on Earth, can alter species composition and interspecies competitiveness. It focuses on the evolutionary aspects of the effects of UV as well as the various synergistic interactions of UV radiation with other environmental factors. Because our knowledge of UV effects on whole ecosystems is still at a relatively early stage, an important part of each chapter is an overview of future research directions and indications of where new date and knowledge is needed.

Available in PDF, EPUB and Kindle. Book excerpt: The research in this book covers papers on a great number of research projects on the responses of plants and crops of natural terrestrial ecosystems, of agro-ecosystems, and of aquatic ecosystems, to enhanced solar UV-B as a result of stratospheric ozone depletion. Some introductory chapters deal with general aspects of how plants respond to UV-B radiation. Photosynthetically Active Radiation (PAR) is a primary energy resource for terrestrial plants, necessary for plant growth. Inevitably terrestrial plants absorb UV-B when exposed to solar radiation. The spectral balance between PAR and UV-B is discussed in several chapters. The responses of plants and ecosystems from the Antarctic and Arctic to enhanced solar UV-B radiation as a consequence of the hole in the ozone layer are considered in some detail. In addition the papers in the book discuss the problem of how responses of plants to UV-B radiation interact with other environmental factors. The book is of great importance for those who are involved in global change topics: biologists, ecologists, earth scientists, agronomists, environmental scientists, and those who develop environmental policy.
Download or read book Stratospheric Ozone Depletion UV B Radiation in the Biosphere written by Robert Hilton Biggs and published by Springer. This book was released on 1994 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Do changes in stratospheric ozone relate to changes in UV-B irradiance and do both relate to life on Earth? This volume presents the latest data available in the basic scientific disciplines associated with these questions. The key topics are the interactive factors between the various research elements and the measurements needed to both validate ozone depletion and monitor UV flux changes in the biosphere.

Download or read book Effect of Stratospheric Ozone Depletion on the Solar Ultraviolet Radiation Incident on the Surface of the Earth written by Pythagoras Cutchis and published by . This book was released on 1973 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent theoretical work indicates that the oxides of nitrogen that would be injected into the stratosphere by a fleet of supersonic transport aircraft could result in a significant depletion of natural stratospheric ozone. Since the stratospheric ozone layer shields the biosphere from harmful ultraviolet (UV) radiation, there is concern about the biological effects of the increase in UV radiation that would attend a reduction in the present amount of natural ozone. The paper estimates the factor by which UV radiation would be increased as a function of percentage ozone depletion and wavelength. To illustrate a potentially significant biological effect of increased UV radiation, the attendant increase in erythemal (sunburn-producing) UV radiation dosage is calculated for several conditions of ozone depletion, radiation wavelength, and solar zenith angle.
