摘要

水分状况和草食如何沿着环境梯度塑造植物的表型变异？Jameel et al.（2024）采用多因子田间普通园地法研究发现，水分有效性和草食性丰度影响多年生草本植物Boechera stricta叶片和生殖性状的表达。表型可塑性、表型曲线和选择方向之间的一致性证明了可塑性在生态相关性状中的适应性。此外，实验操作强调了哪些选择因素推动了这些特征的进化。

Digest: Clinal variation in plant traits is shaped by plastic and evolutionary responses to water regimes and herbivory.

How do water regime and herbivory shape phenotypic variation in plants along environmental gradients? Using a multifactorial field common garden approach, Jameel et al. (2025) showed that water availability and herbivore abundance influence the expression of foliar and reproductive traits in the perennial forb Boechera stricta. The concordance between phenotypic plasticity, phenotypic clines, and the direction of selection demonstrates the adaptive nature of plasticity in ecologically relevant traits. Furthermore, the experimental manipulations highlight which agents of selection drive the evolution of these traits.
