Trait and microhabitat data for sympatric seep monkeyflowers along a soil moisture gradient in San Luis Obispo, CA

Temporal and spatial variation in soil moisture is known to drive phenotypic differentiation within and among plant populations. Here we investigate trait variation and plasticity along a fine-scaled soil moisture gradient between two sympatric monkeyflowers: Erythranthe guttata and a close relative, Erythranthe serpentinicola D.J. Keil (Phrymaceae). E. serpentinicola is endemic to the central coast of California in ephemerally wet serpentine rock outcrops that are adjacent to perennially wet seeps where Erythranthe guttata typically occurs. Morphological, physiological, phenological and soil moisture data data was collected along an environmental gradient from rock outcrop to seep habitats. We collected seed from rock outcrops and seeps to grow under common conditions, then collected morphological, physiological, and phenological data to determine whether the trait divergence in the field was maintained. , Field research took place in the USA, San Luis Obispo County, CA in the City Open Spaces of San Luis Obispo in two different sites near perennial serpentine seeps with surrounding rock outcrops: Laguna Lake Park (33.9036 °N, 117.9398 °W) and South Hills (35.2635 °N,-120.66300 °W). Another site: Irish Hills (35.2522 °N,-120.7031 °W) was excluded from analyses. GPS coordinates provide general locations of each open space, not any rare or threatened species. Lab research took place at California Polytechnic State University, San Luis Obispo, Biological Sciences Department, 1 Grand Ave., San Luis Obispo, CA 93407. Morphological and phenological data was primarily collected using a Survey123 survey form in the field or the greenhouse. Physiological data, stomatal density and specific leaf area (SLA), were collected in the lab at Cal Poly, SLO, and manually added to the data downloaded from Survey123. Raw data was processed and analyzed with R statistical software (v4.1.2; R Core Team 2021)., Windows Excel to open csv files and R statistical software (v4.1.2; R Core Team 2021) for the R markdown and R script files., # Trait and microhabitat data for sympatric seep monkeyflowers along a soil moisture gradient in San Luis Obispo, CA

众所周知，土壤湿度的时空变异会驱动植物种群内部及种群间的表型分化。本研究针对两种同域分布的沟酸浆展开探究，沿精细尺度的土壤湿度梯度分析其性状变异与可塑性：亮黄沟酸浆（Erythranthe guttata）及其近缘种蛇纹石沟酸浆（Erythranthe serpentinicola D.J. Keil，透骨草科（Phrymaceae））。蛇纹石沟酸浆为加利福尼亚中部海岸特有种，仅生于短暂湿润的蛇纹岩露头生境，该生境毗邻常年湿润的渗水生境，而亮黄沟酸浆通常分布于此渗水生境中。研究人员沿从岩露头到渗水生境的环境梯度，收集了形态学、生理学、物候学数据以及土壤湿度数据。我们从岩露头与渗水生境采集种子，于统一可控条件下进行栽培，随后收集形态学、生理学与物候学数据，以验证野外观察到的性状分化是否能够在同质栽培环境中得以保留。

本研究的野外工作在美国加利福尼亚州圣路易斯奥比斯波县的圣路易斯奥比斯波城市开放空间开展，选取两处毗邻常年湿润蛇纹岩渗水生境且周边带有岩露头的样地：拉古纳湖公园（33.9036°N，117.9398°W）与南山丘（35.2635°N，-120.66300°W）。另有爱尔兰山丘样地（35.2522°N，-120.7031°W）未纳入数据分析。本研究提供的GPS坐标仅为各开放空间的大致位置，并非珍稀或受威胁物种的具体分布点。

实验室工作在加利福尼亚州圣路易斯奥比斯波的加州州立理工大学生物科学系开展，地址为：1 Grand Ave., San Luis Obispo, CA 93407。形态学与物候学数据主要通过Survey123表单在野外或温室中采集。生理学数据包括气孔密度与比叶面积（specific leaf area, SLA），于加州州立理工大学圣路易斯奥比斯波分校的实验室中测定，并手动录入从Survey123下载的数据文件中。原始数据通过R统计软件（v4.1.2；R核心团队，2021）进行处理与分析。可通过Microsoft Excel打开CSV文件，使用R统计软件（v4.1.2；R核心团队，2021）处理R Markdown与R脚本文件。
