Abstract Intraspecific functional trait variability
plays an important role in the response of plants to
environmental changes. However, it is still unclear
how the variability differs across three nested spatial
scales (individual, plot, and site) and which determi-
nants (climatic, soil, and ontogenetic variables) shape
the trait variability. Along a latitudinal gradient in
Korean pine broadleaved forest of northeast China, we
quantified the extent of intraspecific variability of four
functional traits in two dominant trees Pinus koraien-
sis and Fraxinus mandshurica at eight sites, including
specific leaf area, leaf dry matter content (morpho-
logical traits) and leaf nitrogen content, leaf phospho-
rus content (physiological traits). Results showed a
large trait variation within and between species
(coefficient variation: 6.07–23.3%). The leaf physio-
logical traits of F. mandshurica and morphological
traits of P. koraiensis were more responsive at site
scale, while the morphological traits of F. mand-
shurica and physiological traits of P. koraiensis were
more responsive at individual scale. In addition,
abiotic and biotic factors explaining functional trait
variation differ markedly between the two tree species,
with physiological trait of F. mandshurica being more
associated with climate and soil, while traits variabil-
ity in P. koraiensis was not affected by climate, soil,
and ontogeny, except for leaf phosphorus content.
Overall, we can predict that the physiological traits of
broadleaved species tend to be more sensitive to
environmental changes, while pines are more sensitive
to competition. It is critical to determine which spatial
scale and trait type should be taken into account in
predictive models of vegetation dynamics.
