abstract = "Reducing uncertainties in the response of tropical forests to
global change requires understanding how intra- and interannual
climatic variability selects for different species, community
functional composition and ecosystem functioning, so that the
response to climatic events of differing frequency and severity
can be predicted. Here we present an extensive dataset of
hydraulic traits of dominant species in two tropical Amazon
forests with contrasting precipitation regimes - low seasonality
forest (LSF) and high seasonality forest (HSF) - and relate them
to community and ecosystem response to the El Nino-Southern
Oscillation (ENSO) of 2015. Hydraulic traits indicated higher
drought tolerance in the HSF than in the LSF. Despite more intense
drought and lower plant water potentials in HSF during the
2015-ENSO, greater xylem embolism resistance maintained similar
hydraulic safety margin as in LSF. This likely explains how
ecosystem-scale whole-forest canopy conductance at HSF maintained
a similar response to atmospheric drought as at LSF, despite their
water transport systems operating at different water potentials.
Our results indicate that contrasting precipitation regimes (at
seasonal and interannual time scales) select for assemblies of
hydraulic traits and taxa at the community level, which may have a
significant role in modulating forest drought response at
ecosystem scales.",
