北极气候变暖导致生态系统中异戊二烯排放量增加。通过实验室和野外测量，研究了温度对北极柳树异戊二烯排放的影响。我们的研究结果表明，每小时的温度响应曲线柳属，北极地区主要的异戊二烯排放灌木，与温带植物一致。与此相反，异戊二烯能力的柳树表现出更大的比预期的平均环境温度的前一天，这是强得多的每日温度响应预测的气体和气溶胶的排放模型（MEGAN）的当前版本。根据这项研究的改进算法，MEGAN预测在北极热浪期间北极柳树的异戊二烯排放量将增加66%。然而，尽管有这些发现，我们仍然无法完全解释高纬度生态系统异戊二烯排放的高温敏感性。
Warming climate in the Arctic is leading to an increase in isoprene emission from ecosystems. We assessed the influence of temperature on isoprene emission from Arctic willows with laboratory and field measurements. Our findings indicate that the hourly temperature response curve ofSalixspp., the dominant isoprene emitting shrub in the Arctic, aligns with that of temperate plants. In contrast, the isoprene capacity of willows exhibited a more substantial than expected response to the mean ambient temperature of the previous day, which is much stronger than the daily temperature response predicted by the current version of the Model of Emissions of Gases and Aerosols from Nature (MEGAN). With a modified algorithm from this study, MEGAN predicts 66% higher isoprene emissions for Arctic willows during an Arctic heatwave. However, despite these findings, we are still unable to fully explain the high temperature sensitivity of isoprene emissions from high latitude ecosystems.
