Fig. 2From: Evolution of asexual Daphnia pulex in Japan: variations and covariations of the digestive, morphological and life history traitsRelationship between genetic distance and phenotypic distance in different trait types between Daphnia pulex clones. Among these, a, d, g, and j showed the relations at the food concentrations of 2.0 mg C L− 1, b, e, h, and k showed the relations at the food concentrations of 0.2 mg C L− 1, and c, f, i, and l showed the relations in the combined data. The correlation coefficient (r) and probability of significance (p) in the Mantel test are shown in each panelBack to article page
