生命事件(物候)的时间可以受到气候的影响。来自世界各地的研究告诉我们,气候线索和物种的反应可以有很大的不同。如果气候变化对物候的影响在一个单一的生态系统中很强,气候变化可能导致生态破坏,但在一个单一的生态系统中,来自不同类群的详细数据是罕见的。我们整理了45年(1975-2020年)来植物,昆虫,鸟类,哺乳动物和两栖动物在高海拔环境中的首次目击和中位数活动。我们将10812个物候事件与气候数据相关联,以确定气候对物种物候影响的相对重要性。我们证明了在一个单一的生态系统中的类群之间的气候-物候联系的显着变化。当前和之前的气候都预测了物候的变化。生物分类群对一些线索的反应相似,如融雪日期和春季温度;其他线索对物候的影响不同。例如,前夏季降水对大多数植物没有影响,推迟了一些昆虫的首次活动,但两栖动物,一些哺乳动物和鸟类的活动提前。比较物候反应的类群在一个单一的位置,我们发现,重要的线索往往不同类群之间,这表明气候的变化可能会破坏类群之间的时间同步。
The timing of life events (phenology) can be influenced by climate. Studies from around the world tell us that climate cues and species' responses can vary greatly. If variation in climate effects on phenology is strong within a single ecosystem, climate change could lead to ecological disruption, but detailed data from diverse taxa within a single ecosystem are rare. We collated first sighting and median activity within a high-elevation environment for plants, insects, birds, mammals and an amphibian across 45 years (1975–2020). We related 10 812 phenological events to climate data to determine the relative importance of climate effects on species’ phenologies. We demonstrate significant variation in climate-phenology linkage across taxa in a single ecosystem. Both current and prior climate predicted changes in phenology. Taxa responded to some cues similarly, such as snowmelt date and spring temperatures; other cues affected phenology differently. For example, prior summer precipitation had no effect on most plants, delayed first activity of some insects, but advanced activity of the amphibian, some mammals, and birds. Comparing phenological responses of taxa at a single location, we find that important cues often differ among taxa, suggesting that changes to climate may disrupt synchrony of timing among taxa.
