Effects of Stratospheric Ozone Depletion and Increased Levels of Ultraviolet Radiation on Subantarctic Forests and Western Patagonian Steppe: A Research Project

摘要

The depiction of stratospheric ozone is a well established fact, supported by remote sensing data, A corresponding increase of solar UV-B radiation reaching the surface of the Earth is being documented. The effects of this increment of UV radiation on living organisms are uncertain. Most of our knowledge of this problem is the result of laboratory experiments and studies on marine phytoplankton of Antarctica. The purpose of this project is to identify and measure indicators of the effect of increased solar LN-B radiation on terrestrial plants. Our goal is to establish these indicators so that we may use them to predict the effects of further increased UV-B radiation on terrestrial ecosystems.
