Species-specific traits plus stabilizing processes best explain coexistence in biodiverse fire-prone plant communities.

Coexistence in fire-prone Mediterranean-type shrublands has been explored in the past using both neutral and niche-based models. However, distinct differences between plant functional types (PFTs), such as fire-killed vs resprouting responses to fire, and the relative similarity of species within a...
