A positive response is indicated by ‘+’, a negative response by ‘–’, no response by ‘0’, no data by ‘N/A’.
Note the different unit for aquatic carnivorous plants (ANaq).
Means ± s.e. whenever possible (or s.d. if indicated).
*Values are in µmol O2 m–2 s–1
†The traps are achlorophyllous; a negative sign of the number indicates CO2 release (i.e. RD).
‡Values are in mg C g tissue–1 h–1; values are from a population in Grassy Lake.
