The present study demonstrates, in mammals, that a population subjected to a high consumption of isoflavones can show a variety of alterations in its individuals, including changes in epigenetic and morphometric characters and in sexual maturation.
Despite overlapping ranges in morphometric characters of pedipalp chela shape, the putative subspecies were easily distinguished by cuticle coloration and condition of the pedipalp chela digital carina, and were also found to differ significantly in burrow architecture and depth.
Notably, morphotypes within the same genetic clade were usually the most divergent in morphometric characters.
The median value for point estimates of heritability for morphometric characters, length, and weight was 0.52 in this study, a value higher than the median value of 0.29 observed from a meta-analysis of heritability for all morphological characters (including morphometric characters, length, weight) across salmonid species [41].
ANOSIM (analysis of similarity test) was used to test the null hypothesis that primary shape of each developed colony, as represented by its morphometric characters, was similar to other colonies' shape in the same experimental group.
Changes in behaviour, size and other morphometric characters are potentially linked to the sexually antagonistic selection response.
Morphometric characters such as weight and size were also measured in all pups.
The morphometric characters were divided into three categories linear, areal and relief aspects of the basin.
Eight morphometric characters of the wing were measured for 76 females (Buga n = 36, Tumaco n = 40) that were compared using univariate and multivariate analyzes.
Morphometric characters showed no obvious departures from normality.
