Correlations of anuran larvae traits with the environmental gradient, based on fourth-corner analysis.

Water body size, PC1 scores of water mass surface area and average depth. Body shape, PC1 scores of mean shapes, obtained by Fourier transformation. Probabilities are shown in bold when P ≤ 0.05.水体大小：对应水体表面积与平均深度的主成分1（PC1）得分。躯体形态：对应通过傅里叶变换（Fourier transformation）得到的平均形态的主成分1得分。当P≤0.05时，概率值以粗体标注。
