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.

Photobiology: The Science of Life and Light, Second edition, is fully updated and offers eight new chapters for a comprehensive look at photobiology. The chapters cover all areas of photobiology, photochemistry, and relationship between light and biology, each with up-to-date references. The chapter authors (of which seven are new) have very different backgrounds, and have produced a truly cross-disciplinary treatise. The book starts with the physics and chemistry of light, and how to handle light in the laboratory and measure it in the field, the properties of daylight, and new uses of light in research. It deals with the evolution of photosynthesis and with the mechanisms of its primary steps. Four chapters deal with how organisms use light for their orientation in space and time: The biological clock and its resetting by light, the light-dependent magnetic compass, and photoperiodism in animals and plants. There are also several medically oriented chapters and two chapters specifically aimed at the photobiology educator.

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.

Photobiology - the science of light and life - begins with basic principles and the physics of light and continues with general photobiological research methods, such as generation of light, measurement of light, and action spectroscopy. In an interdisciplinary way, it then treats how organisms tune their pigments and structures to the wavelength components of light, and how light is registered by organisms. Then follow various examples of photobiological phenomena: the design of the compound eye in relation to the properties of light, phototoxicity, photobiology of the human skin and of vitamin D, photomorphogenesis, photoperiodism, the setting of the biological clock by light, and bioluminescence. A final chapter is devoted to teaching experiments and demonstrations in photobiology.This book encompasses topics from a diverse array of traditional disciplines: physics, biochemistry, medicine, zoology, botany, microbiology, etc., and makes different aspects of photobiology accessible to experts in all these areas as well as to the novice.
