Data from: Accelerated redevelopment of vocal skills is preceded by lasting reorganization of the song motor circuitry

Complex motor skills take considerable time and practice to learn. Without continued practice the level of skill performance quickly degrades, posing a problem for the timely utilization of skilled motor behaviors. Here we quantified the recurring development of vocal motor skills and the accompanying changes in synaptic connectivity in the brain of a songbird, while manipulating skill performance by consecutively administrating and withdrawing testosterone. We demonstrate that a songbird with prior singing experience can significantly...

The effect of environmental heterogeneity on the fitness of antibiotic resistance mutations in Escherichia coli

Alex Wong, Leah Clarke, Adrian Pelin & Michael Phan
Antimicrobial resistance (AMR) is widespread, with resistant pathogens found not only in the clinic but throughout the natural and built environments. It is unclear, however, to what extent AMR should be expected to persist in the environment: Laboratory experiments have suggested that resistance is typically costly, and hence should be selected against. However, such studies may not generalize to broader environmental settings. As such, we estimated the fitness of six AMR mutants of Escherichia coli...
