Variation in leaf shape and size: We think that the results of this research support the hypothesis of an allopatric population divergence of E.
virginica populations, producing variation in fertilization capacity across populations such that our allopatric population comparison captured a contemporary difference.
Simply omitting them would have eliminated 5 of 12 females from the allopatric population, so we used the following approach.
This is true regardless of the order of matings or whether the female is from an allopatric population or a mixed population.
The experimental design consisted of trials in which a gravid female, from either a benthic species or a benthic-like allopatric population, was introduced into the tank of a sexually receptive benthic or limnetic male.

A recent genetic analysis found, that allopatric populations from the two known distribution ranges show the absence of significant phyleographic structure, which indicates the origin of SMPS had a single existing lineage, and a marked haplotypic differentiation among the populations as well that shows a high degree of isolation, mainly in the population of Durango (Oliveras de Ita et al., 2012).
