Fig 1.
Experimental microcosms (A), and experimental design (B) with four treatments and control: Control, Low, and High chironomid larvae density, Bti, and 5 x Bti. Each treatment and the control had three replicates.
Fig 2.
Mean ± Standard Deviation emission rates (n = 3) of CH4 (A), CO2 (B), and O2 consumption (C), and net production rates (n = 3) of CH4 (D) and CO2 (E) for each treatment (Control, Low larvae density, High larvae density, Bti, and 5 x Bti). Significant differences (p ≤ 0.05) between treatments are indicated by different letters.

Linear mixed effect model for the effects of treatment on CH4, CO2 emission and net production, and O2 consumption.
Fig 3.
Mean ± Standard Deviation ratios of emission-to-net production rates (n = 3) of CO2 (A) and CH4 (B) for each treatment (Control, Low larvae density, High larvae density, Bti, and 5 x Bti). Significant differences (p ≤ 0.05) between treatments are indicated by different letters.
