目的物种间气候包膜的比较表明，生态位保守主义倾向于随着时间的推移而瓦解。在这里，我们使用亚洲的树属Platycarya （Juglandaceae）作为案例研究来测试这种趋势在相对较短的时间尺度在一个单一的谱系。再加上对现有文献的重新分析，应该有助于评估利用气候和物种发生数据之间的相关性来推断进化过程的前景。方法利用物种分布模型（SDMs）和多变量分析方法，比较了现今和过去（末次冰期极大期~21ka）两种现存圆果树（Platycarya strobilacea）和长圆果树（Platycarya longipes）之间以及大陆和台湾圆果树种群之间的气候包络，特别关注自相关问题。我们还回顾了在比较物种之间和物种内部气候包膜的类似研究中提供的解释，包括涉及同一物种的本地种群和引进种群的研究。我们发现了杉树的种内分化，而不是种间分化，尽管预测在更老的类群之间生态位分化应该更强。我们的研究还表明，气候包层的分化并不意味着快速的进化分化。虽然sdm可以用来提出进化假设，以便与其他数据验证，但我们得出的结论是，它不应该被用来直接推断短期进化过程。
Aims Comparisons of climate envelopes among species have shown that niche conservatism tends to break down over time. Here, we use the Asian tree genus Platycarya (Juglandaceae) as a case study to test this tendency at relatively short timescales in a single lineage. This, together with a reanalysis of the extant literature, should help evaluate prospects of using correlations between climate and species occurrence data to infer evolutionary processes. Methods We rely on species distribution models (SDMs) and multivariate analyses to compare current and past (Last Glacial Maximum ~21ka) climatic envelopes between the two extant Platycarya species (Platycarya strobilacea and Platycarya longipes) and between mainland and Taiwan populations of P. strobilacea, paying particular attention to autocorrelation issues. We also review interpretations provided in similar studies comparing climate envelopes between and within species, including in studies involving native and introduced populations of the same species. Important Findings We find intraspecific but not interspecific differentiation in climate envelopes of Platycarya, despite the prediction that niche differentiation should be stronger between older groups. Our review also suggests that differentiation in climate envelopes need not imply rapid evolutionary divergence. Whereas SDMs can be used to raise evolutionary hypotheses to be validated with other data, we conclude that it should not be used to directly infer short-term evolutionary processes.
