Hydroclimate and vegetation variability of high Andean ecosystems.

Local temperature presented positive trends over time (R 2 = 0.15 and R 2 = 0.2, p<0.04), as vapor pressure (CRU regional data; R 2 = 0.1, p=0.07), AMO and TSA (global variables; R 2 = 0.5 and R 2 = 0.1, p<0.04), while local precipitation presented a negative trend over time (R 2 = 0.11, p=0.04). 3.5 SAVI, lakes and snow-ice cover relationships The cross correlation between SAVI and lake areas showed a positive association between the complete series in the current and subsequent quarters ( Figure S7 ), with SAVI seasonal fluctuations more pronounced than in lakes, as observed in Figures 2B, D .

We found a positive trend of SAVI over time, probably associated with increasing temperatures.
