Data from: Seed production and 22 years of climatic changes in an everwet Neotropical forest

Examining the cues and drivers influencing seed production is crucial to
better understand forest resilience to climate change. We explored the
effects of five climatic variables on seed production over 22 years in an
everwet Amazonian forest, by analysing the direct effects of these
variables but also how they indirectly influence seed output through their
effects on flower production. We observed a decline in seed production
over the study period, which was primarily explained by direct climate
effects, notably rising nighttime temperatures and decreasing average
water vapor pressure deficit. Conversely, higher daytime temperatures were
positively related to seed output. Rainfall effects on seed production
were more nuanced, showing either positive or negative relationships
depending on the seasonal timing of rains. This study contributes to a
deeper understanding of how changing climatic conditions may impact tree
reproductive output and thereby influence future dynamics and composition
of tropical forests.
