Deciphering fire tolerance of trees at the Amazonia-Cerrado transition by trait-based approach: Implications from species to communities.

ABSTRACT:

Premise

Understanding how fire impacts trees is essential for predicting the effects of novel fire regimes on plant diversity in the transition between the world's two most diverse biomes, the Cerrado and the Amazonia. Here we addressed knowledge gaps regarding physiological damage and mortality in transitional species within fire-prone ecosystems.

Methods

In a manipulative fire experiment, we burned a transitional woodland savanna for six consecutive years after it had been fire-excluded for 33 years. We classified the most abundant tree species according to their fire tolerance and examined the relationship between fire tolerance and key morphological and ecophysiological functional traits. These traits were related to leaf economics spectrum, bark investment, wood density
