latitude, herbivore attack, plant defenses, and climatic data

Ruellia nudiflora population-level values for defenses, herbivore attack, and parasitoid attack. Variables are ordered and labeled in the following way: "population" = plant population name; "latitude" = decimal degrees latitude for each population ; "pctemperature" = z-score values from first principal component of PCA analysis of temperature-related variables (from WorldClim); "pcprecipitation" = z-score values from first principal component of PCA analysis of precipitation-related variables (from WorldClim); "seedphenolics" = concentration of phenolic compounds in seeds; "leafphenolics" = concentration of phenolic compounds in leaves; "fruitattack" = mean proportion of attacked fruits by seed herbivore; "parasitoidattack" = mean proportion of seed herbivores parasitized; "leafdamage" = mean leaf damage score; "trichomedensity" = mean leaf trichome density.本数据集包含裸花芦莉草（Ruellia nudiflora）的种群水平防御性状、植食性昆虫为害以及寄生性天敌寄生为害相关数据。各变量按如下方式定义与排序： - 种群名称（population）：对应植物种群的名称； - 纬度（latitude）：各采样种群的十进制纬度数值； - 温度主成分得分（pctemperature）：源自世界气候数据集（WorldClim）中温度相关变量的主成分分析（Principal Component Analysis，PCA）第一主成分的Z分数值； - 降水主成分得分（pcprecipitation）：源自世界气候数据集（WorldClim）中降水相关变量的主成分分析（PCA）第一主成分的Z分数值； - 种子酚类物质含量（seedphenolics）：种子中酚类化合物的浓度； - 叶片酚类物质含量（leafphenolics）：叶片中酚类化合物的浓度； - 果实被害率（fruitattack）：被种子植食性昆虫侵害的果实平均占比； - 寄生率（parasitoidattack）：被寄生的种子植食性昆虫的平均占比； - 叶片受害程度（leafdamage）：叶片受害程度的平均评分； - 叶片毛状体密度（trichomedensity）：叶片毛状体的平均密度。
