| contents | Contrasting age-dependent leaf acclimation strategies drive vegetation greening across deciduous broadleaf forests in mid- to high latitudes. Wang, Fangyi Xue, Meimei Zhou, Liming Doughty, Christopher E Ciais, Philippe Reich, Peter B Shang, Jiali Chen, Jing Ming Liu, Jane Green, Julia K Hao, Dalei Tao, Shengli Su, Yanjun Liu, Lingli Xia, Jianyang Wang, Han Yu, Kailiang Zhu, Zaichun Zhu, Peng Li, Xing Liu, Hui Zeng, Yelu Yan, Kai Liu, Liyang Lafortezza, Raffaele Su, Yongxian Meng, Yanqiong Pan, Yixuan Yang, Xueqin Fu, Yongshuo H He, Nianpeng Yuan, Wenping Chen, Xiuzhi Plant Leaves Forests Acclimatization Trees Seasons Climate Change Photosynthesis North America Europe Increasing leaf area and extending vegetation growing seasons are two primary drivers of global greening, which has emerged as one of the most significant responses to climate change. However, it remains unclear how these two leaf acclimation strategies would vary across forests at a large spatial scale. Here, using multiple satellite-based datasets and field measurements, we analysed the temporal changes (Δ) in maximal leaf area index (LAI) and length of the growing season (LOS) from 2002 to 2021 across deciduous broadleaf forests (DBFs) in the middle to high latitudes. Contrary to the widely held assumption of coordination, our results revealed a negative correlation between ΔLAI and ΔLOS. Notably, the trade-offs between ΔLAI and ΔLOS were strongly explained by stand age. Younger DBFs, with lower baseline LAI, predominantly located in eastern Asia, displayed an increase in LAI with small changes in LOS. This acquisitive strategy facilitated younger DBFs to grow more photosynthetically efficient leaves with low leaf mass per area, enhancing their light use efficiency. Conversely, older DBFs with a higher baseline LAI, primarily located in North America and Europe, extended their LOS by increasing leaf mass per area. This conservative strategy facilitated older DBFs to produce thicker, but less photosynthetically efficient leaves, resulting in decreased light use efficiency. Our findings offer new insights into the contrasting changes in leaf area and growing season length and highlight their divergent impacts on ecosystem functioning. |
