With the continuous increase in human population and its constant demands on the aquatic environment, there has been a compounding of the interrelationships between algae and man. These relatively simple green plants not too long ago were often considered as merely biological curiosities. Within the past twenty-five years, with advances in technology and the increased eutrophication of lakes and streams, the interplay between algae and man has become more complex and more im portant. Problems of taste, odor, toxicity, or obnoxious growth caused by algae are unfortunately quite familiar to the water supplier and to the public health worker. Algae have met their role in the space age as a poss...
As editor of the two-part Volume V on photosynthesis in RUHLAND'S Encyclopedia, the forerunner of this series published in 1960, I have been approached by the editors of the present volume to provide a short preface. The justification for following this suggestion lies in the great changes which have been taking place in biology in the two decades between these publications, changes which are reflected in the new editorial plan. Twenty years ago it appeared convenient and formally easy to consider photo synthesis as a clearly separated field of research, which could be dealt with under two major headings: one presenting primarily photochemical and biochemical prin ciples, the other physiolog...
Photophysiology, Volume I: General Principles: Action of Light on Plants focuses on the fundamental mechanisms by which non-ionizing radiations affect the living cell at the molecular level when such analysis is possible. The selection first offers information on the development of photochemistry, including photosynthesis, photoaxis, vision, phototropism, diurnal rhythms and visible light, and medical uses of ultraviolet light. The text then takes a look at the principles of photochemistry and photochemical methods and electron spin resonance and its application to photophysiology. The publication examines the photochemical action of light on macromolecules, absorption spectra, spectrophotometry, and action spectra, and photochemical reactions of photosynthesis. Discussions focus on photosynthetic phosphorylation, measurement and interpretation of action spectra, instrumentation for absorption spectra, and inactivation of viruses by visible and ultraviolet light. The selection is a valuable source of information for readers interested in photophysiology.
"the book is a valuable source of information and reference and may also inspire young researchers on how to advance their own field of plant science. This discovery book, which is recommended to a wide readership from advanced students to the established scientists, should be present in all central libraries and all libraries of plant biology institutions".Journal of Plant Physiology, 2000
