Description Seasonal and site wise variation in size and diversity of bacterial population was observed in Schirmacher Oasis, Antarctica. Prevailing soil temperature limited the distribution and abundance of groups of bacteria like psychrophiles, psychrotrophs and mesophiles. Pulses in the bacterial cycle were also found in the Basis as a function of daily and seasonal variations in air and soil temperature. Requirement of growth temperature of individual bacterium is the best physiological marker to workout the survival strategies of microorganisms. Effect of seasonal variations in temperature was directly manifested in diversity index and generation time of microorganisms. In temperature response study, organisms like @iSerratia@@ were found tolerating very low temperatures (-40 degrees C), indicating the physiological adaptation of bacteria to sub-freezing temperatures, persisting in Schirmacher Oasis, during Antarctic winter
