In late June, some LEVeg members joined the #68thIAVS Symposium in Gijón! We presented some of our new research and ideas and took part in great discussions on vegetation science. Thank you, @iavs5.bsky.social

What happens when you have a prescribed fire at the end of the dry season, fire of high severity with T>700ºC? The Cerrado blooms! 45 days post-fire and a high proportion of the spp flowering and fruiting. Isn’t that amazing? #Cerrado #FireEcology @leveg.bsky.social @programabiota.bsky.social

🔥🌱 From the #AJB Special Issue: “Understanding novel #fire regimes using plant trait‐based approaches" 🌱🔥 Deciphering fire tolerance of #trees at the Amazonia–Cerrado transition by trait-based approach: Implications from species to communities Wesley Jonatar Cruz, et al. doi.org/10.1002/ajb2...
How do trees survive fire at the Amazon-Cerrado transition? This graphical abstract reveals how different strategies, like thicker bark, bud protection, and water use efficiency help species survive (or not) in fire-affected areas. The study findings show that fire not only selects the most resilient trees but also reshapes the entire community structure over time.

Yesterday the BRIVAC, a volunteer fire brigade, did a prescribed fire during the II Seminário Regional do Manejo Integrado do Fogo. In Brazil, local volunteers are essential for the success of fire management, including during wildfires. Bravo BRIVAC!
