Decoupling of Taxonomic and Functional Recovery in a Multi‐Decadal Mixed Araucaria Forest Chronosequence

open access: yesAustral Ecology, Volume 51, Issue 8, August 2026.
ABSTRACT Understanding how different biodiversity dimensions recover following disturbance is critical for interpreting forest successional trajectories. We examined this question in a protected remnant of Araucaria Mixed Forest (AMF) in subtropical southern Brazil, a frost‐prone montane system with multiple anthropogenic disturbance legacies.

Regional-Scale Assessment of Burn Scar Mapping in Southwestern Amazonia Using Burned Area Products and CBERS/WFI Data Cubes

open access: yesFire
Fires are one of the main sources of disturbance in fire-sensitive ecosystems such as the Amazon. Any attempt to characterize their impacts and establish actions aimed at combating these events presupposes the correct identification of the affected areas.

Escalating Fire‐Driven Forest Loss in Protected Tropical Forests

open access: yesGlobal Change Biology, Volume 32, Issue 8, August 2026.
More than 4 million hectares of protected tropical forest have been lost to stand‐replacing fire since 2001, with annual losses increasing through time in both the Americas and Africa. Protection most commonly reduced the proportion of stand‐replacing fire, but could not decouple temporal fire trends inside PAs from those outside.

Carbon Stocks in Sugarcane Biomass and Their Implications on Land Use Change CO2 Balance in Brazil

open access: yesGCB Bioenergy, Volume 18, Issue 8, August 2026.
This paper develops a regionalized carbon stock factor for sugarcane biomass in Brazil, showing that sugarcane cultivation can lead to net carbon removal in most municipalities. The findings improve greenhouse gas inventories and support bioenergy policies by providing more accurate, spatially resolved estimates for land use change emissions.

Spatial Scale Modulates the Effect of Habitat Amount on Diversity Patterns of Arachnid Assemblages Across Different Brazilian Ecosystems

open access: yesJournal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim We evaluated how native vegetation cover influences the diversity of arachnid assemblages across multiple spatial scales in major Brazilian ecosystems. Location Brazil (Amazon and Atlantic rainforests, Cerrado savanna and Caatinga dry forest). Taxon Arachnida (Opiliones, Pseudoscorpiones and Scorpiones). Methods We sampled arachnids at 120
