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.

This story is absolutely wild. Did you know that avocados change sex over the course of a day? And that it's controlled by a single ancient balanced polymorphism? This is flat our crazy

Before flowers evolved with attractive colors and scents, what did plants use to attract insect pollinators? Heat may be one ancient strategy.

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/...
), we find the opposite: animals exchange genes more, and for longer, than plants
