The paper shows that nutrient enrichment, especially with nitrogen and phosphorus, reduces C4 plant cover in grasslands, disrupting climate-driven C3-C4 balance globally.

The paper predicts and validates the temperature sensitivity of stem respiration, showing thermal acclimation reduces global carbon emissions.

The study examines how drought and nitrogen availability affect leaf nitrogen content and photosynthetic rates in sunflower, finding that nitrogen uptake is impaired under drought and low nitrogen.
