Stable isotope niche metrics for each lizard population and the whole sample.

TA = Total area of convex hull; SEAB = Bayesian standard ellipse area; CR = δ13C range; NR = δ15N range; CR = Mean distance to centroid; MNND = Mean nearest neighbour distance; n = bivariate sample size.Stable isotope niche metrics for each lizard population and the whole sample.TA为凸包总面积(Total area of convex hull)；SEAB为贝叶斯标准椭圆面积(Bayesian standard ellipse area)；CR为碳同位素δ¹³C范围(δ¹³C range)；NR为氮同位素δ¹⁵N范围(δ¹⁵N range)；另有CR为到质心的平均距离(Mean distance to centroid)；MNND为平均最近邻距离(Mean nearest neighbour distance)；n为二元样本量(bivariate sample size)。本数据集涵盖各蜥蜴种群及全部样本的稳定同位素生态位指标。
