Variation in response to water availability across Phlox species
收藏资源简介:
Plants adapt to environmental variation both by evolving divergent trait means and by plastically adjusting trait expression in response to local conditions. While these dual strategies are essential for persistence in diverse environments, how they interact and vary across closely related species is understudied. For plants, water availability is a particularly important selective force that shapes species distributions, selects for growth habit and life history strategy, and can dictate individualsâ plastic expressions of trait values and reproductive success. Here, we use ecological niche modeling, field soil collections, and a controlled drought experiment to test how biogeography and evolutionary history influence responses to limited water availability in three closely related Texas annual Phlox species and their F1 hybrids. We infer that the species occupy distinct niches that diverge along a primary axis of water availably and soil moisture. Each species has a distinct..., , # Reference Information ## Provenance for this README * File name: README.md * Authors: Christina Steinecke, Julius A.

植物通过两种途径适应环境变化:一是演化出分化的性状均值,二是通过表型可塑性(phenotypic plasticity)调整性状表达以响应局地环境条件。尽管这两种策略对于在多样环境中存续至关重要,但目前对它们如何相互作用,以及在近缘物种间的差异模式仍研究不足。 对植物而言,水分可利用性是尤为关键的选择压力:它不仅塑造物种分布格局,筛选出适配的生长型(growth habit)与生活史策略(life history strategy),还能决定个体的性状表型可塑性表达与繁殖成功率(reproductive success)。 本研究借助生态位模型(ecological niche modeling)、野外土壤采样与受控干旱实验,探究生物地理学(biogeography)与演化历史(evolutionary history)如何影响三种近缘德克萨斯州一年生福禄考(*Phlox*)物种及其F1杂种(F1 hybrid)对水分受限条件的响应。我们推断,这些物种占据了沿水分可利用性与土壤湿度这一主轴分化的独特生态位。每个物种均具有独特的…… # 参考信息 ## 本README文件来源 * 文件名:README.md * 作者:克里斯蒂娜·施泰内克(Christina Steinecke)、朱利叶斯·A·塔宾(Julius A.
