New fully funded PhD or MPhil position in my lab at the University of Adelaide! Please share widely! Thanks

Please pass along - postdoc position! with our working group on #FunctionalTraits and rarity. This is part of the FREE (Functional Rarity in Ecology and Evolution) working group led by Cyrille Violle in Montpellier France 🧪🌐🌾 emploi.cnrs.fr/Offres/CDD/U...

🚨 📣 Happy to share this new paper on World Seagrass Day 🌱🌊🌱🌊

Community trajectory analyses sheds light on regional and local dynamics of 2️⃣ seagrass species along the 🇫🇷 coast

Nice ! Can I be added too ? Thanks !

Change in the cluster composition of the Beware Reef. This site shiffted into an urchin barren in 2013 as show by the disaperence of large canopy algae (dark blue line).

🌍 Understanding habitat states & transitions is key for conservation!

🏝️ Helps track ecosystem shifts from climate change

🛑 Detects early warning signs of degradation (e.g., kelp loss → urchin barrens).

Description of the identified clusters along with photoquadrats examples. Arrows indicate transitions between clusters.

🌍 With our data-driven standardized way to classify & monitor marine habitats, what did we find?

🏝️ 17 distinct habitat states, including kelp forests, coral reefs & transitional zones

📉 Our pipeline captures fine-scale ecological changes over time

Map of the number of RLS transect sampled per ecoregion.

This study wouldn’t be possible without citizen scientists! 🌍🌊

👩‍🔬 Reef Life Survey divers collected 6554 transects worldwide
📸 Standardized photoquadrat sampling ensured consistency
📊 It enabled us to track habitat transitions over time

Using SHAP to Interpreting this cluster as a Foliose brown algae cluster.

Machine learning models like UMAP & HDBSCAN are powerful, but they’re often hard to interpret.

So, we used SHAP to:
📌 Identify which features drive cluster formation
📌 Uncover non-linear interactions in benthic ecosystems
📌 Improve ecological interpretability of results

UMAP ordination of the benthic cover data. Each point is coloured accordingly to its cluster. Black points represent unclustered data.

We used better methods: UMAP (for dimension reduction) & HDBSCAN (for clustering).

✅ Captures complex ecological structures
✅ Finds clusters of varying shapes & sizes
✅ Filters noise instead of forcing data into clusters

Clustering is widely used in ecology to define community types, habitat states & biodiversity patterns. But common methods used in ecology have major drawbacks. (See this excellent video of @JohnDataHealy

🚀 New paper alert! We used a UMAP-HDBSCAN pipeline to classify & track benthic habitat states at a global scale using citizen science data from Reef Life Survey ! 🌍🏝️
