摘要
The prediction of vegetation responses to 氣候 requires a knowledge of how 氣候-sensitive plant traits mediate not only the responses of individual plants, but also shifts in the 物種 and functional compositions of whole communities. The emission of isoprene gas - a trait shared by one-third of tree 物種 - is known to protect leaf biochemistry under climatic stress. Here, we test the hypothesis that isoprene emission shapes tree 物種 compositions in tropical 森林s by enhancing the tolerance of emitting trees to heat and drought. Using 森林 inventory data, we estimated the proportional abundance of isoprene-emitting trees (pIE) at 103 lowland tropical sites. We also quantified the temporal composition shifts in three tropical 森林s - two natural and one artificial - subjected to either anomalous warming or
