These savanna plants can survive fire. How do they do it?
Researchers at São Paulo State University (UNESP) have investigated some of the mechanisms used by plants in the Cerrado, a savanna-like ecosystem in Brazil, to defend themselves and regenerate quickly after a fire.

Researchers at São Paulo State University (UNESP) have investigated some of the mechanisms used by plants in the Cerrado, a savanna-like ecosystem in Brazil, to defend themselves and regenerate quickly after a fire.
The history of the savanna-like vegetation of the Cerrado is significantly influenced by fire. The plants residing there have developed a variety of ways to withstand flames, which their diverse lineages have improved and optimized via a lengthy evolutionary process.
“We’ve known since we began studying the biome that the Cerrado’s plants have thick bark to protect their internal tissues. They also have a wide array of below-ground organs that enable them to resprout because they’re protected by being under the surface,” said first author, Marco Antonio Chiminazzo, a PhD candidate at UNESP in Rio Claro.
