The micropopulations differed greatly in the proportion of traps with animal prey (mean 26%), trap proportion to total biomass (1.4-42%, mean trap biomass, and maximum trap size. CO2 compensation points ranged from 0.7 to 6.1 μM (mean 2.6 μM). A weak HCO3- use (compensation point 0.51 mM) was found in plants growing in alkaline water. Trap biomass proportion did not correlate significantly with prey capture and CO2 compensation points with ambient [CO2]. A very rapid apical growth (2.5-4.2 new nodes day-1) occurred in sand-pits. CO2 compensation points resembled those known in other aquatic non-carnivorous plants. They did not reflect carnivory.
