title: Structural differences of the microbial community in two sites of the Terra Nova Bay (Ross Sea, Antarctica): a statistical analysis.
abstract: The microbial community structure was investigated in a one month survey at two sampling stations located in the Terra Nova Bay (Antarctica). The microbial assemblage was studied by direct counts with epifluorescent microscopy (picoplankton and picophytoplankton), fractionated adenosine-triphosphate, lipopolysaccarides and bacterial growth on cultural medium. The results underwent the Spearman rank correlation and the principal component analysis together with other environmental parameters (temperature, salinity, nutrient salts and chlorophyll a) with the aim of revealing differences in the microbial community structure between the in-shore and off-shore sites.
