The transposable elements have an important influence to create genetic variability necessary for adaptation of populations and evolution of species. This project concerns the study of the impact of TEs on the evolution of genomes, populations and species. Knowledge of the mechanisms by which genomes and populations regulate the activity of these elements is a fundamental question of population genetics and functional genomics. In two subprojects, we intend to investigate the dynamics of dispersion and activity of TEs in the genomes of related species, as well as in their hybrids, using as a model closely related species (D. melanogaster and D. simulans, D. mojavensis and D. arizonae) and evaluate the effect of this dynamic intrinsic to the elements (sub-class they belong to, the overall proportion in the genome and specific number of inserts) or the species (population size, ancestral state elder or colonizer of sampled populations, and hybridization) and environment (temperature and specific habitats that they occupy).
