尽管许多物种随着气候变化而改变其物候，但物种在这些反应的方向和大小(即物候敏感性)上存在显著差异。越来越多的研究发现非本土物种的早期物候或对气候高度敏感，这可能在变暖的气候中有利于非本土物种而不是本土物种。然而，相对较少的研究明确比较了原生和非原生物种之间或原生和引进范围内非原生种群之间的物候对气候的反应，限制了我们量化物候在入侵成功中的作用的能力。在这里，我们回顾了支持和反对在原生和非原生物种以及原生和引进的非原生物种种群中物候和气候敏感性差异的经验证据。与通常的假设相反，本地和非本地植物物种在平均物候或物候敏感性上并不总是不同。然而，非本地植物物种对气候的敏感度往往与本地植物相同或更高，但很少不那么敏感。引进的非本地植物种群通常表现出比相同物种的本地种群更早的繁殖，但有混合证据表明，引进植物种群和本地植物种群之间的物候敏感性存在差异。我们发现很少有研究比较本地和外来动物的物候学。未来的工作应该表征原生与非原生动植物物种、原生与引进非原生物种种群以及不同入侵阶段的物候对气候的敏感性，并应仔细考虑气候变化下物候差异如何可能促进入侵成功或对原生物种不利。
Although many species shift their phenology with climate change, species vary significantly in the direction and magnitude of these responses (i.e., phenological sensitivity). Studies increasingly detect early phenology or high phenological sensitivity to climate in non-native species, which may favor non-native species over natives in warming climates. Yet relatively few studies explicitly compare phenological responses to climate between native vs. non-native species or between non-native populations in the native vs. introduced range, limiting our ability to quantify the role of phenology in invasion success. Here, we review the empirical evidence for and against differences in phenology and phenological sensitivity to climate in both native vs. non-native species and native and introduced populations of non-native species. Contrary to common assumptions, native and non-native plant species did not consistently differ in mean phenology or phenological sensitivity. However, non-native plant species were often either just as or more sensitive, but rarely less sensitive, to climate as natives. Introduced populations of non-native plant species often show earlier reproduction than native populations of the same species, but there was mixed evidence for differences in phenological sensitivity between introduced and native plant populations. We found very few studies comparing native vs. invasive animal phenology. Future work should characterize phenological sensitivity to climate in native vs. non-native plant and animal species, in native vs. introduced populations of non-native species, and across different stages of invasion, and should carefully consider how differences in phenology might promote invasion success or disadvantage native species under climate change.
