Tree selection
We conducted a paired design to compare arthropod communities associated
to male and female trees of B. cordata . We selected thirteen
pairs of male and female individuals of B. cordata with similar
traits: diameter at breast height (DBH), tree coverage (measured as a
vertical projection of exposed leaf area), and the tree height. Because
the environment in the reserve is highly heterogeneous, we chose pairs
of trees with individuals that were within 10 m of each other, to
control for any neighborhood effect and for any microclimate effect. We
report and statistically compare the characteristics of the trees in
Supplemental Materials II.
