Regulation of the abundance and growth of ciliates in a newly-flooded reservoir

摘要

The specific growth rates of ciliates were measured in diffusion chambers after the first flooding of a reservoir. The abundance of nanoplankton and the high concentrations of dissolved organic matter could explain why the growth rate, whose average value was 0.07 +/- 0.06 h(-1), was higher than that recorded in other lakes of similar trophic status. The abundance of ciliates was strongly controlled by Daphnia longispina and Asplanchna priodonta. [References: 28]
