Cross-correlation graph: A) monthly mean temperature vs. litterfall and B) monthly total precipitation vs. litterfall.
Fig 4.
Anomalies: A) monthly total precipitation (mm month-1), B) monthly mean temperature (°C), C) monthly maximum temperature (°C), D) monthly minimum temperature (°C), and E) total litterfall (g.d.w. m-2 day-1). Red lines delimit the period of coincidence between climatic variables and litterfall. Shadow gray is the confidence interval of 95%.
Table 2.
Litterfall anomalies related to monthly climatic anomalies and/or daily (cyclonic events), considering a maximum lag of 2 months (previous) and showing the direction of each anomaly (MxT = maximum temperature, MnT = minimum temperature, MeT = mean temperature, P = total precipitation, Ce = cyclonic event).
