(A–C). Changes in ecosystem CO2 fluxes (mean ± s.e.) with respect to the month, year and grazing intensity during the growing and grazing period in 2010, 2011, 2012, 2013 and 2014. The bars represent the means of three replicate plots (±s.e.). Different letters indicate significant differences among the CO2 fluxes in different months, years and grazing intensities.
