Abstract: 

Using body length data from 72 populations over the species range we analyzed how male size, female size, and sexual size dimorphism (SSD) is associated with our explanatory variables. We revealed a moderate effect of reproductive mode (larger female size and higher SSD in viviparous vs. oviparous populations) and a strong but complex effect of seasonality: across the lineages, as well as within the Eastern Viviparous lineage, female size and SSD increase with increasing seasonality, whereas the Western Viviparous lineage followed the opposing trends.
