The existence of endangered tree species in Mexico necessitates an understanding of their
vulnerability to the predicted climate changes (warming and drying trends). In this study, the
sensitivity to climate of earlywood (EW) and latewood (LW) widths of the threatened Picea
chihuahuana was determined. The response of EW and LW to climate variables (maximum
temperature, minimum temperature, precipitation, evaporation, and a drought index) was
analyzed by means of correlation analysis using dendrochronology over the period of 1950 …
