Abstract

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.
