A comprehensive framework for seasonal controls of leaf abscission and productivity in evergreen broadleaved tropical and subtropical forests

Summary: Relationships among productivity, leaf phenology, and seasonal variation in moisture and light availability are poorly understood for evergreen broadleaved tropical/subtropical forests, which contribute 25% of terrestrial productivity. On the one hand, as moisture availability declines, tre...

On the one hand, as moisture availability declines, trees shed leaves to reduce transpiration and the risk of hydraulic failure. On the other hand, increases in light availability promote the replacement of senescent leaves to increase productivity. Here, we provide a comprehensive framework that relates the seasonality of climate, leaf abscission, and leaf productivity across the evergreen broadleaved tropical/subtropical forest biome. The seasonal correlation between rainfall and light availability varies from strongly negative to strongly positive across the tropics and maps onto the seasonal correlation between litterfall mass and productivity for 68 forests. Where rainfall and light covary positively, litterfall and productivity also covary positively and are always greater in the wetter sunnier season. Where rainfall and light covary negatively, litterfall and productivity are always greater in the drier and sunnier season if moisture supplies remain adequate; otherwise productivity is smaller in the drier sunnier season. This framework will improve the representation of tropical/subtropical forests in Earth system models and suggests how phenology and productivity will change as climate change alters the seasonality of cloud cover and rainfall across tropical/subtropical forests. Public summary: • Three climate-phenology regimes are identified across tropical and subtropical forest biomes • Where light and water limit plant in dry season, litterfall and productivity peak in sunny wet season • Where light or water alternately limits plant, productivity peaks in wet season with low litterfall • Where water does not limit plant, litterfall and productivity peak in sunny dry seasonXueqin YangJianping WuXiuzhi ChenPhilippe CiaisFabienne MaignanWenping YuanShilong PiaoSong YangFanxi GongYongxian SuYuhang DaiLiyang LiuHaicheng ZhangDamien BonalHui LiuGuixing ChenHaibo LuShengbiao WuLei FanPierre GentineS.
