Code to support 'Climate change caused contrasting acclimation of leaf longevity in global pantropical moist forests'

Leaf longevity (LL) is a fundamentalplanttrait that largely explains theecosystem functional dynamicsinglobal pantropical moist forests.However, the sign, magnitude, and mechanisms of the spatiotemporal variations in LLwith ongoing climateare stilllacking. Usingboth ground measurements andstate-of-the-art remote sensing techniques, we analyzed the continental-scale variability of annual mean LL over 2001-2023. We found contrasting changes in LLthatinAmazonand tropical Asiawith average LL>~1.8 yrs, LLdecreased due to rising temperature and intensified atmospheric dryness.In contrast,opposite trends were observed in Congo andsubtropical Asiawhere hasLL < ~1.8 yrs.Thesecontrasting changescaused a convergence in leaf longevityofpantropical moist foreststhat has not been reported. Furthermore, we show that such changes have important ecological implications for forestsurvivalwith optimizedplant traits, photosynthesis, and species evenness, whichwere expected to better resist climate variability.Our study provides emerging evidence forlarge-scalepantropicalLLacclimation under climate change.
