Lack of population differentiation patterns of previously identified putatively adaptive transposable element insertions at microgeographic scales

[Background] Transposable elements (TEs) play an important role in genome function and evolution.

Sumario:[Background] Transposable elements (TEs) play an important role in genome function and evolution. It has been shown that TEs are a considerable source of adaptive changes in the genome of Drosophila melanogaster. Specifically, footprints of selection at the DNA level, the presence of population differentiation patterns across environmental gradients, and detailed mechanistic and fitness analyses of a few candidate adaptive TEs pointed to the role of TEs in environmental adaptation. However, whether the population differentiation patterns observed at large geographic scales can be replicated at a microgeographic scale has never been assessed before.
