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.

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.
