Figure 2: Species of
maple differ widely in
their habitat preference.
Understorey species, such
as mountain maple (Acer
spicatum) (upper photo),
have been shown to have
a high (less negative) leaf
turgor loss point whilst
maples from relatively
dry environments, such
as bigtooth maple (Acer
grandidentatum) (lower
photo), produce much
lower (more negative) leaf
turgor loss values during
summer (-1.6 MPa/-232
psi and -3.8 MPa/-551
psi respectively, in the
Sjöman et al. 2015 study).
