Description Dimorphism estimates and information about analyzed populations. Status indicates whether reasonable dimorphism estimates could be obtained ("OK") or why they could not be found. ∆BIC is the difference in support between the best one- (BIC1) and two-group (BIC2) models, with positive values indicating greater support for the two-group model. CovStruct refers to the assumptions of the best supported model about how variance/covariance patterns are similar across sexes (see Table 1); CovStruct Selection indicates whether the CovStruct assumption was the best supported among all those implemented in Mclust ("best model") or if only a subset of models were considered ("imposed", with "imposed E_I" indicating that only models EEI, EVI, and EII were allowed). Combining data left and right valves requires specifying a method for this offset (LR offset method); see text for details. Dimorphism, female area and female L/H data were all natural-log transformed.

Description Methods used to determine the offset between left and right valve data, illustrated with the population HAP_NANI-1. (A) Original data, before any offset is applied. As is typical for many cytheroids, right valves are smaller and more elongate than left valves. Note also that the sex ratios appear to differ between the sexes: most right valves are from the larger, male cluster, whereas the majority of left valves are females. This shifts the mean of right valves towards that of males, and the mean of left valves towards that of females. When valve means are used to determine left-right offsets (B), right valves are now systematically smaller and less elongate because the skewed sex ratios have resulted in an overcorrection for right valves away from male-like values. In contrast, fitting the mixture model while allowing left-right offsets to be freely optimized (C) provides a much better overlay of left and right valve data.
