💡 Why it matters:
Long-term data are irreplaceable for understanding ecosystem resilience, variability, and responses to climate change. Sustained support for long-term ecological research is vital to guide adaptive management and policy decisions.

📈 What we found:
Even after two decades of measurements, predictions of ecosystem behavior remained highly variable and nonlinear. Short-term datasets often miss emergent and unexpected dynamics that only become evident with long-term observation.

🔍 What we did:
We analyzed more than 20 years of aboveground net primary production (ANPP) and precipitation data across three dryland ecosystems, spanning a grassland-to-shrubland transition in central New Mexico. We quantified how model predictive capacity evolves as more data accumulate.

🌎 Support for Long-Term Ecological Studies Matters Now More Than Ever

I am excited to share our new paper: “Long-term ecological studies must continue: insights from a dryland transition zone” co-authored with Huong LE, Ph.D. and Scott Collins.

🌱 What we found:

- Soil respiration temperature thresholds vary across vegetation types and climates.

- Soil moisture strongly interacts with temperature responses.

- A single “universal” temperature response is not enough for accurate carbon-cycle models.

☀️New research in Environmental Research Letters

We show how climate limits the CO₂ fertilization effect on forest productivity. Warming may ease this in boreal zones, but tropical forests face a tougher tradeoff.
