The effects of UVB radiation on temperate southern hemisphere forests

The temperate forests of the southern hemisphere are the most likely forests to be affected by increased levels of ultraviolet-B (UVB) radiation resulting from reduced ozone. The review describes these forests and then discusses the morphological changes, physiological effects, and protection mechanisms, particularly UV absorbing compounds that result from present day and increasing UVB radiation. Possible avenues for future research are explored. - Solar UVB has a variable but generally modest effect on the morphology and growth of forest trees, but may modify forest community composition
