The incorporation of [ 3 H](methyl)thymidine into DNA by the planktonic heterotropic bacteria of Little Crooked Lake (Noble Country, IN) was determined at different incubation temperatures. The highest rates of thymidine incorporation generally occurred at temperatures exceeding the in situ temperature of the sample. The optimal temperature for thymidine incorporation ranged from 1.0–3.4 times the in situ temperature. As the summer of 1983 progressed, the optimal temperatures for thymidine incorporation by epilimnetic samples and the in situ temperatures converged. This trend was reversed as fall overturn was approached.
