Serra das Araras??

The NEOFire team has now finished another experimental fire campaign at Serra das Araras! This is the 8th consecutive year we burn savanna plots to investigate the effects of altered fire regimes on the Cerrado

Is there a potential to strengthen ecological processes as a way to restore fire regimes?

Can tropical rainforest trees keep their cool? Now out in @globalchangebio.bsky.social we explored whether intraspecific variation in leaf energy balance was a result of adaptation to local climate.

Local Adaptation Drives Leaf Thermoregulation in Tropical Rainforest Trees

We tested whether tropical rainforest trees adjust their leaf traits and resulting leaf temperatures across their distributions within the Australian Wet Tropics. Using field measurements from across...

What drives photosynthesis temperature sensitivity? New #GCB paper from #MichaletzLab grad #JosefGaren uses #FAsTeR to show it's 1‑day weather, not traits, origin climate, or phylogeny!

Simone Reis & colleagues show why Amazon transitional forest is vulnerable to drought.
Typical savannas dominated by shrubs and small trees resist it, but adjacent ecosystems with bigger trees ("Cerradao") suffer large productivity losses, especially below-ground.

Sensitivity of tropical woodland savannas to El Niño droughts

Abstract. The 2015–2016 El Niño event led to one of the hottest and most intense droughts for many tropical forests, profoundly impacting forest productivity. However, we know little about how this ev...

Overall, the symposium brought together a good range of experts and topics. We agreed on the importance of integrating research efforts across disciplines, scales and social contexts. Our aim is that this and other conversations can help achieve a better conservation and understanding of the Cerrado

10) Finally, @manumachadoeco.bsky.social closed the symposium by talking about developing a new Cerrado degradation framework. Because degradation is typically addressed as loss of biomass in forest ecosystems, her aim is to redefine and quantify degradation within the open landscapes of the Cerrado

Francisco Navarro-Rosales @navarrosales.bsky.social · Jul 7

9) More broadly, Vera Arruda from @ipam-amazonia.bsky.social presented her work analysing fire regime changes in the Cerrado biome from 1985 to 2022 (using Landsat satellite imagery from the @mapbiomas.bsky.social Fire Collection 2). She focused on recurrence, land-use distribution and area of fires

Francisco Navarro-Rosales @navarrosales.bsky.social · Jul 7

8) Paulo Bernardino then talked about the use of multispectral and thermal drone imagery to map Cerrado wetlands, focusing on identifying the optimal spatial resolution for accurate classification at Chapada dos Veadeiros. He highlighted the potential of upscaling wetland mapping with satellite data

Francisco Navarro-Rosales @navarrosales.bsky.social · Jul 7

7) @tashlutz.bsky.social then talked about her work developing a novel method to estimate fuel loads across the Cerrado using a multi-scale data fusion approach. She is quantifying structure and accumulation of surface, herbaceous and woody fuels, providing insights into fire impacts and probability

Francisco Navarro-Rosales @navarrosales.bsky.social · Jul 7

6) After lunch, @alefidelis.bsky.social re-opened the session by talking about the history of fire management in Brazil. She described the fire experiment at Serra do Trombador and its many cool results, highlighting the importance of long-term collaboration and integration with non-academic actors

Francisco Navarro-Rosales @navarrosales.bsky.social · Jul 7

5) Prof Vânia Pivello from USP closed our morning session. She spoke about the use of fire as a management tool to stimulate the flowering of Eriocaulaceae by traditional harvesters at Sempre-Vivas National Park, where late-season fires result in slow recovery of plant cover, composition and height

Francisco Navarro-Rosales @navarrosales.bsky.social · Jul 7

4) Prof Reuber Brandão from the UnB presented his team’s research on the role of termite mounds as wildlife fire refuges in the Cerrado. Because temperature and humidity in termite mounds remain constant during fire, they can hold up to 71 individuals from 14 species of reptiles and amphibians!

Francisco Navarro-Rosales @navarrosales.bsky.social · Jul 7

3) I then presented the results of my second PhD chapter investigating how the fire regimes at Serra das Araras influence woody productivity of Cerrado trees; and how productivity responses are explained by bark protection and photosynthetic functional traits at high fire intensity @biology.ox.ac.uk

1 1 1

Francisco Navarro-Rosales @navarrosales.bsky.social · Jul 7

2) Wesley Cruz then presented the research he has led within the CERFogo Team, looking at ecological strategies of trees in response to experimental burning (focusing on resprouting dynamics across regimes and traits influence on tree fire tolerance, recently published at doi.org/10.1002/ajb2...)

Francisco Navarro-Rosales @navarrosales.bsky.social · Jul 7

1) The symposium was opened by @ioliverasmenor.bsky.social who introduced the conservation challenges of altered fire regimes in the Cerrado and presented an overview of the CERFogo project at Serra das Araras (aiming to monitor the long-term use of fire as a strategy for biodiversity conservation)

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):

Francisco Navarro-Rosales @navarrosales.bsky.social · Jul 7

In this paper led by Wesley Cruz we used the burning experiment at Serra das Araras to study the fire tolerance of Cerrado trees. We examined the relationship between fire tolerance and morphological/ecophysiological traits @ioliverasmenor.bsky.social @umramap.bsky.social @manumachadoeco.bsky.social

Botanical Society of America @botsocamerica.bsky.social · Jul 3

🔥🌱 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.
