Definition code forsampling location Calendar year Season (winter, spring, summer and autumn, defined as begining on the winter solstice, spring equinox, summer solstice and autumnal equinox respectively) in which the site was sampled. The seasonal rate of M. pyrifera biomass production in units of wet mass (kg m-2 day-1). This variable is calculated by integrating the instantaneous rate of production during each period and dividing by the number of days (as described in Section I.B Equation 2). Production for all days in each season is averaged. The seasonal rate of M. pyrifera biomass production in units of dry mass (kg m-2 day-1). This variable is calculated by integrating the instantaneous rate of production during each period and dividing by the number of days (as described in Section I.B Equation 2). Production for all days in each season is averaged. The seasonal rate of M. pyrifera biomass production in units of carbon mass (kg m-2 day-1). This variable is calculated by integrating the instantaneous rate of production during each period and dividing by the number of days (as described in Section I.B Equation 2). Production for all days in each season is averaged. The seasonal rate of M. pyrifera biomass production in units of nitrogen mass (kg m-2 day-1). This variable is calculated by integrating the instantaneous rate of production during each period and dividing by the number of days (as described in Section I.B Equation 2). Production for all days in each season is averaged. The seasonal growth rate of M. pyrifera wet mass (day-1). This variable is calculated as the growth rate necessary to explain the observed change in biomass during each period, given the initial biomass and the independently measured loss rates (see Section I.B Equation 1). Growth rates for all days in each season are averaged. The seasonal growth rate of M. pyrifera dry mass (day-1). This variable is calculated as the growth rate necessary to explain the observed change in biomass during each period, given the initial biomass and the independently measured loss rates (see Section I.B Equation 1). Growth rates for all days in each season are averaged. The seasonal growth rate of M. pyrifera carbon mass (day-1). This variable is calculated as the growth rate necessary to explain the observed change in biomass during each period, given the initial biomass and the independently measured loss rates (see Section I.B Equation 1). Growth rates for all days in each season are averaged. The seasonal growth rate of M. pyrifera nitrogen mass (day-1). This variable is calculated as the growth rate necessary to explain the observed change in biomass during each period, given the initial biomass and the independently measured loss rates (see Section I.B Equation 1). Growth rates for all days in each season are averaged. The standard error in our estimate of NPP in units of wet mass (kg m-2 d-1). This error is produced using Monte Carlo methods, as described in Section I.B Quantifying Uncertainty. It incorporates errors in estimates of biomass, plant loss rates and frond loss rates. The standard error in our estimate of NPP in units of dry mass (kg m-2 d-1). This error is produced using Monte Carlo methods, as described in Section I.B Quantifying Uncertainty. It incorporates errors in our estimates of biomass, plant loss rates and frond loss rates. The standard error in our estimate of NPP in units of carbon mass (kg m-2 d-1). This error is produced using Monte Carlo methods, as described in Section I.B Quantifying Uncertainty. It incorporates errors in our estimates of biomass, plant loss rates and frond loss rates. The standard error in our estimate of NPP in units of nitrogen mass (kg m-2 d-1). This error is produced using Monte Carlo methods, as described in Section I.B Quantifying Uncertainty. It incorporates errors in our estimates of biomass, plant loss rates and frond loss rates. The standard error in our estimate of the growth rate of wet mass (day-1). These data are produced using Monte Carlo methods, as described in Section I.B Quantifying Uncertainty. The error in our estimate of growth incorporates errors in our calculations of biomass, plant loss rates and frond loss rates. The standard error in our estimate of the growth rate of dry mass (day-1). These data are produced using Monte Carlo methods, as described in Section I.B Quantifying Uncertainty. The error in our estimate of growth incorporates errors in our calculations of biomass, plant loss rates and frond loss rates. The standard error in our estimate of the growth rate of carbon mass (day-1). These data are produced using Monte Carlo methods, as described in Section I.B Quantifying Uncertainty.
