In response to the overwhelming concern for possible acute and
long-term effects of ozone depletion on terrestrial and aquatic
life, this volume presents a comprehensive collection of review
articles from an internationally acknowledged group of experts.
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.
It is intended primarily for graduate students and for researchers
who wish to look outside their speciality, but can also act as a
source of information for undergraduate students.
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.

Emphasis is on human health, with chapters on skin cancer, DNA, and
vitamin D. Written for photobiologists, dermatologists, and
biophysicists, this is the most thorough treatment of the subject
available.
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 new edition of this authoritative text provides an
interdisciplinary treatise of all aspects of the interactions
between light and the living world. It starts with a description of
the physics of light, and how to deal with it in experiments and
observations. The phenomena described in the rest of the book
covers all organisms: how light is used by organisms for obtaining
energy for life processes, for gathering information about the
environment, and for communicating with others of the same or other
species. The book also describes "bad" effects of light in causing
disease or contributing to formation of environmental toxins. New
techniques used by scientists to investigate life processes using
light are also explored in the volume. Written by experts in the
field, Photobiology: The Science of Life and Light, 3e is a
valuable and accessible resource for both advanced undergraduates
and established researchers.
