Figure 1. Effect of experimental treatments ong1 estimates for all tested species. Panel a
represents species grown in the closed canopy (n = 982) and panel
b represents species from the open canopy (n = 1604). Species on
each panel are organized with increasing drought tolerance from left to
right in accordance with Niinemets and Valladares (2006). Whiskers
extend to the largest or lowest value but no further than 1.5 times the
interquartile range above and below the hinges of the box plot with the
median. Any observations outside this range are denoted as individual
points. The horizontal line inside the box denotes the median of the
values.
