图5. 基于表型距离与地理距离(欧式距离)的Mantel检验。
A, 基于999次随机拟合Mantel检验结果, 观测值(0.562 8)显著偏离零假设(无空间结构)下的拟合均值(p = 0.009)。B, 表型距离与地理距离的相关性图, 彩色斑块为基于距离值的二维核密度估计结果, 单核表明符合渐变群模式。
Fig. 5. Mantel test between morpho-distance and geo-distance (Euclidean distance).
A, Mantel test based on the 999 times of permutations. B, Correlation plot between morpho-distance and geo-distance. The single consistent cloud of point based on the 2-dimensional kernel density estimation indicates that the variation pattern of populations is a cline.
