Data from: New genome assemblies for Poeciliidae: A foundation for adaptation studies

Multiple lineages in the family Poeciliidae have independently adapted to
hydrogen-sulfide-rich springs. The independent colonizations of such
springs mean that there are naturally replicated lineages that provide a
powerful model for studying adaptation and convergent evolution. However,
there are limited genomic resources for many genera and species across
Poeciliidae. Here, we present six high-quality, chromosome-level,
annotated genome assemblies for Poecilia and Gambusia populations, five of
which are the first for the species or ecotype, and the remaining assembly
improved the current reference genome contiguity by more than 100-fold. We
compare repeat content and model historical changes in effective
population size using these new assemblies.
