Fig. 2: Interactive effects and source-specfic CO2 production.
From: Zooplankton carcasses stimulate microbial turnover of allochthonous particulate organic matter
a Non-additive interactive effects measured as CO2 production in daphnia and leaves combined treatments compared to the sum of CO2 produced when daphnia and leaves were isolated (for DL1:3 and DL1:5, controls were calculated based on the CO2 production per mg daphnia or leaves in the controls for treatment DL1:1). a CO2 concentrations derived from the different carbon sources calculated with the two-source mixing model for the total amount of respired CO2 and b normalised by the amount of daphnia and/or leaf material in each treatment (n = 4). Daphnia: daphnia only; D:L: daphnia and leaves in a given ratio with a complex microbial community; Leaves: leaves only; b-DL1:1: daphnia and leaves (ratio 1:1) with a bacterial community only.
