A just a quick last note: the paper was the culmination of many (7ish?) years of work by the lab group and our NutNet collaborators. A big thanks to @alissarcheaib.bsky.social who did the heavy lifting to finally take this thing across the finish line and discover many new insights in the process!

These results can provide a basis for improving how terrestrial carbon-nitrogen interactions are simulated in land surface models

the response to light availability is muted, but warrants further investigation, as we have seen evidence for this in other manipulation experiments (e.g., academic.oup.com/jxb/article/...)

And this plays out in the dataset! That is, we see that the responsiveness of leaf nitrogen to soil nitrogen increases with aridity and decreases with temperature of the sites

From theory (nph.onlinelibrary.wiley.com/doi/10.1111/...) we think that leaf nitrogen demand increases with light and aridity and decreases with temperature

The paper uses leaf chemistry data from the #NutrientNetwork to explore how leaf nitrogen responds to soil nitrogen across environments
