Therefore DTR was the predominant factor affecting CO2 exchange.
However, CO2 fluxes showed a weakly positive correlation with TDS
(r ¼ 0.20, p ¼ 0.08, n ¼ 80). Additionally, CH4 fluxes significantly
correlated with TDS, air temperature and water table (Table 3),
indicating that they were the predominant factors influencing CH4
fluxes.
