in the water columns of two ultra-oligotrophic, freshwater
Antarctic lakes (Crooked Lake and Lake Druzhby) during an annual
cycle. In both lakes bacterial production, measured by the
incorporation of [H-3] thymidine, continued in winter and showed
a cycle over the year. The range of production was between 0 and
479 ng C L-1 h(-1) in Crooked Lake and 0-354 ng L-1 h(-1) in
Lake Druzhby. 2. Abundance and mean cell volume both varied,
producing marked changes in biomass during the year, with
highest biomass occurring in the winter and early spring.
Biomass showed similar seasonal trends in both lakes. 3. For
most of the year inorganic forms of nitrogen and pho
