Fire modulates the structural drivers and functioning of individual‐based plant‐pollinator networks

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Ecological drivers that shape (positively or negatively) the plant‐pollinator network and determine plant fitness, both before and after a fire. Abstract Fire is a natural phenomenon that shapes ecosystems, but climate change and human activities have increased its frequency and magnitude, disrupting essential ecosystem services like pollination ...

A pedo‐isotopic approach to study sandy soils of the Brazilian Cerrado in Piauí State

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Sandy soils dominate Brazil's Cerrado biome in Piauí State, yet their organic carbon (OC) stabilization mechanisms and landscape‐driven pedogenesis remain poorly understood. To clarify this topic, the present study proposes a pedo‐isotopic approach to characterize six representative Brazilian Cerrado soils derived from sedimentary rocks in ...

Linking leaf traits and litter flammability using a novel framework, tested with Brazilian Cerrado trees

open access: yesFunctional Ecology, Volume 39, Issue 5, Page 1247-1261, May 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In tree‐dominated ecosystems, the behaviour of surface fires is largely controlled by the structure of fine fuels. Because leaves make up most of the fine fuels, the traits of those leaves—their size, shape and leaf area for a given mass—help determine the impacts of ...

Fire Effects on Bird Communities From Seasonally Flooded Forests Along Amazonian Black Water Rivers of the Negro River Basin

open access: yesDiversity and Distributions, Volume 31, Issue 5, May 2025.
ABSTRACT Aim Fire significantly contributes to Amazonian degradation, with igapó forests (seasonally flooded by blackwater rivers) being especially vulnerable. Igapó forests support species adapted to seasonal flooding, making fire a critical threat to these specialised organisms.
