Table 2 Summary of results for MANOVA analyses for treatment and experiment on different response variables. “All” indicates that all three experiments were included in the analysis; “AZ only” indicates that only the Arizona experiments were included. The covariates in all analyses were pre-treatment values of those variables. Newly Emerged Bee (NEB) dry weight data were only collected in Arizona and CO2 data were only collected in the AZ 2018 study.
