Data used in: Santi et al. (2020) Phenotypic differentiation in a heterogeneous environment: morphological and life-history responses to ecological gradients in a livebearing fish. Journal of Zoology 310(1): 10-23.

This file contains three separate datasets. The first data sheet provides centroid size and all relative warps derived from geometric morphometric analysis of all fish used in the study. The second data sheet provides all life-history traits quantified for male and female <i>P. januarius</i>, while the third data sheet provides the Embryo Dry Weight and Embryonic Stage of Development data used to calculate the Matrotrophy Index for our manuscript.

本文件包含三个独立数据集。第一张数据表提供了本研究中所用全部鱼类经几何形态测量分析得到的质心大小与所有相对扭曲值。第二张数据表包含了针对雄性和雌性<i>P. januarius</i>量化得到的全部生活史性状；第三张数据表则提供了胚胎干重与胚胎发育阶段数据，用于计算本研究论文的母体营养指数。
