A bit late, but really happy to see my first PhD paper out!
We studied trait-elevation relationships in multiple traits spanning growth, size (both above and belowground) and leaf economics to understand whether these align at within- and among-species scales.

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...

At the same time, we made thousands of synonymous mutations in endogenous yeast genes and measured their growth. We used careful statistics and controls. Only 3%, 204 of 6874, had a fitness effect! This goes against a controversial recent result that most synonymous mutations had fitness effects.
