Abstract	:	Lake Matano, Indonesia, is an ancient lake that provides an opportunity to examine the factors governing planktonic community structure. I determined that the phytoplankton community exhibits very low biomass relative to other lakes with similar assemblages and physicochemical characteristics. Phosphate additions made to algal cultures in lake water produced significant growth, suggesting that phosphorus availability limits production. To test for metal toxicity, phytoplankton were grown in water treated by flocculation. The enhanced growth in these cultures is consistent with the removal of a toxic constituent during flocculation. Ecological characterization of the secondary production revealed a depauperate community populated by the endemic calanoid Eodiaptomus wolterecki, and Tropocyclops species, in each year sampled (2000, 2002, 2004). Poor reproductive potential was suggested by the low proportion of egg-bearing individuals (less than 0.1%) in each year.
