Characteristics of the tree-ring chronologies_ N — Number of sampled trees per plot (in parenthesis: total number of dendrochrono-logical samples); Period — time range of the sampled cores; TRW — mean ring-width value; MC — mean correlation between series at each plot; MS — mean sensitivity; EPS — mean Expressed Population Signal, RBAR — average correlation between all series_
| Plot | N | Period | TRW (mm) | MC | MS | EPS | RBAR |
|---|---|---|---|---|---|---|---|
| EMN | 19(21) | 1964-2010 | 1.56 | 0.518 | 0.470 | 0.74 | 0.16 |
| EMF | 13(17) | 1960-2010 | 1.52 | 0.505 | 0.419 | 0.58 | 0.12 |
Geographical and hydrological settings of the sampled plots_ EMN — El Mateo near; EMF — El Mateo far_ DRB — plot distance from the riverbank_ GWD — groundwater depth_
| Plot | Altitude (m) | DRB (m) | GWD (m) | Latitude (°S) | Longitude (°W) |

Model parameters (explanatory variables), significance (p), slope and adjusted coefficient of determination (R2adj_) for the “optimal model” of each dependent variable_ StrFI — Streamflow; P — Precipitation_ SDJFM referred to the mean streamflow values of September, December, January, February and March months_
