Figure 5.3 Potentially defensive attributes of plants includin gtotal phenolics (left), condensed tannins (center),
and toughness (right) from TDF (open boxes) and TRF (shaded boxes), comparing the total conglomerate of species of
each forest type (upper panels) and the species separated accordin gto their phenolo gy in TDFs and growth habit in
TRFs (lower panels). Data represent medians, quartiles (25–75% and 5–95%), and extreme values.∗P<0.05,
