As the planet warms and forests burn, can we replant them with new trees that will thrive in the decades ahead? Learn more: scim.ag/3TPgT5p
Bar chart showing forest area burned in high-severity burns from 1984 to 2021. Each bar has a black dot with error bars, representing the estimated planting need and middle 50% of estimates. Since 2000, the average annual area burned in high-severity fires has increased fivefold, relative to 1984 to 1999.

🌍 Why it matters: With more droughts on the horizon due to climate change, forest management needs to be species- & site-specific. Want the full details? Read the article here: 🔗 doi.org/10.1016/j.fe... 🔚 5/5

💡 The takeaway: Competition reduction isn't a one-size-fits-all solution. Beech sees a trade-off: 🌿 more growth, but at very low competition, more drought stress. For oak? Thinning didn't make much difference. 🌰 🧵4/5

Koenraad Van Meerbeek @kvanmeerbeek.bsky.social · 03/03/2025
🔬 How was it studied? 72 point dendrometers tracked daily water deficit (drought stress proxy) & growth along a competition gradient. 🌳📊 This gave a detailed look at how trees respond to competition & climate conditions. 🧵3/5

Koenraad Van Meerbeek @kvanmeerbeek.bsky.social · 03/03/2025
🌱 Key findings: • Less competition boosted beech growth! 📈 • But... it sometimes made beech more drought-stressed. • Oak? Unbothered—competition had no clear effect. • Climate factors (rain ☔ & vapor pressure deficit 💨) influenced both species. 🧵2/5

Take-home message: ML-based EWS offer a scalable, data-driven way to predict and mitigate abrupt shifts in dryland ecosystems—essential in the face of climate change and increasing pressure on these vital regions (6/6)

Koenraad Van Meerbeek @kvanmeerbeek.bsky.social · 03/01/2025
The study focused on the Sudano–Sahelian drylands, a region highly vulnerable to climate change. Predictions for 2025 highlight a southern belt with high probabilities of abrupt ecosystem shifts, linked to long-term rainfall trends🌍🌱 (5/6)

Koenraad Van Meerbeek @kvanmeerbeek.bsky.social · 03/01/2025
Machine learning (ML) to the rescue! We used ML to analyze complex patterns in satellite data. By integrating resilience metrics (e.g., autocorrelation) with vegetation, rainfall, and other environmental factors, we achieved 75.1% accuracy and 76.6% precision (4/6)
130
Koenraad Van Meerbeek @kvanmeerbeek.bsky.social · 03/01/2025
Current methods for EWS rely on metrics like temporal autocorrelation to detect loss of resilience. However, applying these to large-scale satellite data is tricky due to noise & short time series. So, what’s the solution? 🤔 (3/6)
120
Koenraad Van Meerbeek @kvanmeerbeek.bsky.social · 03/01/2025
The problem: Drylands face degradation that threatens their ability to act as carbon sinks & provide resources. Abrupt shifts in ecosystem functioning—like desertification—can occur when thresholds are crossed. Early warning systems (EWS) are urgently needed (2/6)

Koenraad Van Meerbeek @kvanmeerbeek.bsky.social · 03/01/2025

💡 Why does this matter? By incorporating extremes, our approach makes SDMs more robust for conservation and ecological applications. This method is broadly applicable, transferable across species, and relies on widely available data (6/6)
010
Koenraad Van Meerbeek @kvanmeerbeek.bsky.social · 16/12/2024
📊 Key results: While overall model performance improved modestly, the biggest gains were at range edges. These are critical areas for conservation planning, where accurate predictions are vital to managing species under climate change (5/6)

Koenraad Van Meerbeek @kvanmeerbeek.bsky.social · 16/12/2024
4/ 🌳 What did we do? We tested this approach on 28 European tree species. By incorporating GEV-derived parameters on climatic extremes, our model: ✅ Improved performance at range edges (AUCedge) ✅ Narrowed niche predictions ✅ Outperformed state-of-the-art methods (4/6)

Koenraad Van Meerbeek @kvanmeerbeek.bsky.social · 16/12/2024
🛠️ Our solution? We integrate the Generalized Extreme Value (GEV) distribution into SDMs to better account for rare climatic extremes. The GEV distribution is a powerful tool from extreme value theory, widely used in analyzing climatic data (3/6)
100
Koenraad Van Meerbeek @kvanmeerbeek.bsky.social · 16/12/2024
Current SDMs often overlook the role of extreme events, especially at the edges of species' ranges—where conditions are already less favorable. These gaps can lead to inaccurate predictions, especially under climate change (2/6)
