abstract = "Competition among trees is an important driver of community
structure and dynamics in tropical forests. Neighboring trees may
impact an individual tree{\^a}s growth rate and probability of
mortality, but large-scale geographic and environmental variation
in these competitive effects has yet to be evaluated across the
tropical forest biome. We quantified effects of competition on
tree-level basal area growth and mortality for trees {\^a}¥10-cm
diameter across 151 ~1-ha plots in mature tropical forests in
Amazonia and tropical Africa by developing nonlinear models that
accounted for wood density, tree size, and neighborhood crowding.
Using these models, we assessed how water availability (i.e.,
climatic water deficit) and soil fertility influenced the
predicted plot-level strength of competition (i.e., the extent to
which growth is reduced, or mortality is increased, by competition
across all individual trees). On both continents, tree basal area
growth decreased with wood density and increased with tree size.
Growth decreased with neighborhood crowding, which suggests that
competition is important. Tree mortality decreased with wood
density and generally increased with tree size, but was apparently
unaffected by neighborhood crowding. Across plots, variation in
the plot-level strength of competition was most strongly related
to plot basal area (i.e., the sum of the basal area of all trees
in a plot), with greater reductions in growth occurring in forests
with high basal area, but in Amazonia, the strength of competition
also varied with plot-level wood density. In Amazonia, the
strength of competition increased with water availability because
of the greater basal area of wetter forests, but was only weakly
related to soil fertility. In Africa, competition was weakly
related to soil fertility and invariant across the shorter water
availability gradient. Overall, our results suggest that
competition influences the structure and dynamics of tropical
forests primarily through effects on individual tree growth rather
than mortality and that the strength of competition largely
depends on environment-mediated variation in basal area. © 2020
