The combined effects of temperature (22 and 32°C) and the concentration of Pb (0; 0.05; 0.1 and 0.2 mg L- 1) on the competition between B. havanaensis and B. rubens using population growth was evaluated. At 22°C; increase in Pb concentration had little effect on the population growth of B. havanaensis; while it had adverse effect on B. rubens. At this temperature; the presence of B. rubens had adversely affected the growth of B. havananensis. However; under similar conditions; B. rubens was not influenced by B. havanaensis. Increase in Pb concentration decreased the population growth of B. havanaensis at 32°C regardless whether the population was alone or together with B. rubens. When grown alone; B. havanaensis was numerically more abundant than B. rubens. B. havanaensis grown at 32°C had population growth rates of 0.32 to 0.56 day- 1; depending on Pb level and the presence of competitor. At this temperature; B. rubens had mostly negative growth rates. Further; our study showed that Pb at a concentration as low as 0.05 mg L- 1 had adverse effect on B. rubens at both the temperatures. Though B. rubens is known to occur naturally at wide temperature range; in our study this species appeared to have adapted to low temperature. Copyright © Taylor & Francis Group; LLC;
