Carbon starvation as a mechanistic explanation for the gradual decline of savanna ground-layer species under tree encroachment
AbstractBackground. Tropical savannas worldwide have been experiencing woody encroachment, i.e. the rapid increase in density and biomass of woody plants i

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

The Cerrado is really amazing! Post-fire flowering is one of the most interesting and beautiful fire response! It is not a response of a specific species or family! Bulbostylis paradoxa never fails and can be seen flowering already 18 hs after fire! @leveg.bsky.social @programabiota.bsky.social
We just did the 153th burn since 2013 in our plots! In each burn we measured different fire parameters like fire intensity, fuel load, fire temperature, etc. Thanks to all students, local people and the fire brigade who helped in all experimental fires! @leveg.bsky.social @programabiota.bsky.social

Last week, the @oxfordecosystems.bsky.social team and I participated in the ATBC2025 meeting in Oaxaca, México. It was great to see so many cool research presentations! During the event, @manumachadoeco.bsky.social and I organised a symposium about Cerrado fire ecology and conservation (see thread):

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!
II Seminário Regional do Manejo Integrado do Fogo: local event, organized by the volunteer fire brigade of Cavalcante, where everyone can talk about their favorite topic: working with fire. Scientist, society, government, traditional peoples and volunteers.
This sedge never stops amazing me: first picture was taken 18 hours after fire; second picture - 36 hours post-fire. Detail: this was an early-dry season fire! Bulbostylis paradoxa fire-super star 🔥🔥🔥🔥
Burning for the 7th time our early-dry season fire plots. We have established the fire experiment in 2013 with 5 treatments related to fire frequency and season. At each fire, we sample fire parameters. Twice a year, we sample vegetation and biomass.
