Scientists are now one step closer to unveiling the mystery of Amazon forest fires. A recent study led by Carla Staver, a Yale ecology and evolutionary biology associate professor, found that variation in bark thickness correlates with sensitivity of trees to fire in Amazonian forests. Specifically, Staver discovered that thinner bark — which is more often present in wetter forests — leads to higher tree mortality from fire. The finding allows researchers a look into the extent of forest degradation from fire in the Amazon. “Fires, which occur more often during droughts in tropical forests, can kill trees,” Staver said. “This paper helps us to understand which trees are most likely to die in fires.”
