🌐🌴 Current global hunting threat maps treat species as equally at risk everywhere in their range. We attempted to address this by combining where hunters actually go with which species are most likely to be targeted and least able to cope, for 6k+ trop. birds and 4k+ mammals: doi.org/10.32942/X24...

In a recent paper @pnas.org, we found that the world’s oceans sort into six recurring “food-web types” shaped by temperature, productivity, and depth—functionally alike even when the species aren’t.

Some argue protected areas in fire-prone landscapes can undermine forest carbon (fuel build-up → higher fire risk). This paper shows Spanish protected areas consistently outperform comparable unprotected lands, strongest in National Parks. iopscience.iop.org/article/10.1...

New paper out in @methodsinecoevol.bsky.social! 📷We present TropiCam-AI: a machine learning model that identifies 84 taxa of Neotropical arboreal mammals and birds from camera-trap images and videos. 🐒🦜 📃Paper → doi.org/10.1111/2041-210x.70213 🌐Project → github.com/andrewzamp/TropiCam-AI
An arboreal camera-trap image form the Brazilian Amazon rainforest. An animal is detected by TropiCam-AI, which analyzes its features and tries to determine what species it is.TropiCam-AI analyzes the prompted image, and classifies it at the species level as a black spider monkey. Users can decide to let the model predict at the taxonomic level that achieves the highes confidence and accuracy, or force predictions at the desired taxonomic level.

Finally it is here! 🥳 We simulated 280 virtual species under current and future scenarios testing multiple background levels. Background optimization can improve model performance for current scenarios, but not so much for future ones. Also 5% of the study area sampled as bg seems to be the best.

We show that marine communities around the world exhibit trophic convergence in similar environments — a global pattern echoing what we also found on land. This challenges classic biogeographic models and opens new doors for predicting biodiversity responses to change. www.pnas.org/doi/10.1073/...

Despite its promise, spatial conservation prioritisation (SCP) remains underused. In @natrevbiodiv.bsky.social, I argue that SCP must evolve beyond the scientific methodology to embrace the social and political contexts in which conservation decisions are made. www.maraujolab.eu/2025/03/31/c...
