Super glad to see this work finally out after a seemingly endless review process. This paper improved greatly from these reviews and I’m grateful for reviewers that provide thorough and constructive feedback.

We also find that nitrogen-water use tradeoffs were not modified by soil pH, indicating that previous studies that note effects of soil pH on nitrogen-water use tradeoffs may really be demonstrating implicit soil nutrient effects on these tradeoffs

We show that trees maintained photosynthesis rates across a nitrogen fertilization gradient by trading less efficient nitrogen use for more efficient water use, providing strong support for nitrogen-water use tradeoffs predicted from first principles of photosynthetic least-cost theory

This work was also a contribution to the @lemontree-uofr.bsky.social group. I am super proud of the work and am glad it's finally out for all to read and engage with!

(6/6)

This work helps resolve the longstanding question as to whether nitrogen supply or demand drives plant responses to eCO2, showing that nitrogen demand regulates leaf-level responses to eCO2 and nitrogen supply constrains whole-plant responses

(5/6)

Whole-plant responses to elevated CO2 were enhanced with increasing nitrogen fertilization, supporting the large body of work indicating that nitrogen limitation constrains whole-plant responses to elevated CO2. Inoculation played no role in modifying whole-plant responses to elevated CO2 (4/6)

We found strong evidence suggesting that leaf-level photosynthetic responses to elevated CO2 were not modified by nitrogen fertilization or inoculation treatments. Instead, results indicate strong support for photosynthetic acclimation responses expected from eco-evo optimality theory (3/6)
