Diversification of the shell shape and size in Baikal Candonidae ostracods inferred from molecular phylogeny.

Directional asymmetry was large and statistically highly significant (p < 0.0001) for both shape (F above 55) and size (F above 92), prompting us to analyze separately the right valve (RV) and the left valve (LV).

Total allometry (calculated as a linear regression of Procrustes coordinates onto log transformed centroid size (CS)) in the RV species-averages dataset was significant (p = 0.0011) and accounted for almost 14% of total variability; while the evolutionary allometry (calculated as a regression of independent contrasts of shape onto independent contrasts of log transformed CS) was around 10% and was barely significant (p = 0.047).
