Brief Description (Abstract):

The decrease in total column ozone shall lead to enhanced levels of UV-B doses, capable of limiting the life forms over Antarctica. Organisms which are not accustomed to high level of UV-B radiation will get suppressed and photoautotrophic production will decline. If the primary producers are threatened it will be difficult for the survival of organisms at higher trophic level. Algae, mosses and lichens are the common floral elements of Antarctica and are characterized by adaptations essential for survival on harsh environmental conditions. Three different plants, i.e., Spirogyra sp., Bryum argentinum and Xanthuria elegans, which are naturally growing, around Indian research station ?Maitri?, East Antarctica, were analyzed for the presence of UV-B absorbing compounds. Concentrations of UV-B absorbing compounds and phenolics were higher in B. argentinum and X. elegans as compared to Spirogyra sp.

Status: Completed

Purpose: During the 24th Indian Scientific Expedition to Antarctica studies on the UV-B radiations and induction of UV absorbing pigments were carried out with the aquatic algae, moss and lichens growing around Indian research station Maitri, Schirmacher Oasis, East Antarctica.
