Environmental variables grouped in different dry season climate zones. (A) elevation; (B) distance from the coast; (C) mean daily dry season atmospheric water potential (Ψatm); (D) percent of time cloud cover is present at sample plots at midmorning during the summer dry season; (E) average daily maximum temperature during June–August over a 30-year interval; (F) average total annual rainfall over a 30-year interval interpolated for each plot. Capital letters represent significant differences between zones based on Tukey’s HSD post hoc tests. Box plot represents median, 25th–75th percentile (box outline), 5th–95th percentile (whiskers), and maximum and minimum values beyond the 5th –95th percentiles (circles).
