DNA methylation patterns linked to salinity and geography in the American eel (<i>Anguilla rostrata</i>).

ABSTRACT: The panmictic American eel (Anguilla rostrata) displays a wide range of intraspecific phenotypic variation as well as geographical sex bias and differential recruitment. By definition, panmictic species lack genetic structure, thus local adaptation through genetic variation cannot explain the presence of intraspecific variation. As a result, the contrasting phenotypes observed in the American eel could be attributed to either spatially varying selection, phenotypic plasticity (often mediated through epigenetic changes), or the interaction of both processes. Here we explore, for the first time, the role of DNA methylation in acclimatization in a panmictic species, the American eel, as well as its association with salinity and geography in Northeastern Canada.
