Temporal stability of sex ratio distorter prevalence in natural populations of the isopod Armadillidium vulgare
Temporal stability was also generally reflected in mitochondrial and nuclear variation. Nevertheless, in a population, a Wolbachia strain replacement coincided with changes in mitochondrial composition but no change in nuclear composition, thus constituting a typical example of mitochondrial sweep caused by endosymbiont rise in frequency. Rare incongruence between Wolbachia strains and mitochondrial haplotypes suggested the occurrence of intraspecific horizontal transmission, making it a biologically relevant parameter for Wolbachia evolutionary dynamics in A. vulgare.
