了解物种的种群趋势和分布范围动态对于全球物种保护至关重要。自人类世以来,随着人类活动强度的持续升级,全球物种遭受了栖息地的急剧丧失和分布范围的缩小。由于大部分原栖息地因人类活动出现各种方式的退化,动物会迁移到新的栖息地以获得更大的生存机会。这种动态的种群分布范围对于物种的生存至关重要,与种群灭绝的概率直接相关。因此,了解种群分布动态变化的机制并识别驱动因素对于预测和指导种群的保护至关重要。

大气CO2浓度升高不仅加剧了全球气候变化,还改变了动植物的生长发育过程。其中,对C3植物最重要的影响是增加了光合作用,并降低气孔导度。而植物气孔导度的降低导致植物蒸腾作用降低,水分利用率增加,对蚜虫这类取食植物韧皮部汁液的刺吸式口器昆虫来说,寄主植物保持相对高的水势和膨压对蚜虫被动取食、获取植物汁液非常重要。在调节水分利用效率和叶片气孔的张开程度过程中,植物脱落酸(ABA)信号途径发挥至关重要的作...
