Schall and Heinrichs question our interpretation that the climatic debt in understory plant communities is locally modulated by canopy buffering. However, our results clearly show that the discrepancy between microclimate warming rates and thermophilization rates is highest in forests where canopy cover was reduced, which suggests that the need for communities to respond to warming is highest in those forests.
沙尔和海因里希斯对我们的解释提出了质疑,认为林下植物群落的气候债务是由树冠缓冲作用在当地进行调节的。然而,我们的研究结果清楚地表明,在树冠覆盖减少的森林中,微气候变暖率与嗜热化率之间的差异最大,这表明群落对变暖的响应需求在这些森林中最高。
