Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change

Global Change Biology, Volume 32, Issue 4, April 2026.
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Phytochemical and Biological Evaluation of Leaves, Stems, and Roots of Schinus weinmanniifolia Mart. Ex Engl.

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
Ethanolic extracts from leaves, stems, and roots of Schinus weinmanniifolia Mart. ex Engl. were evaluated for phytochemical composition and biological activities. The extracts exhibited antioxidant, photoprotective, and antimicrobial activity, without hemolytic effects or cytotoxicity at active concentrations. Syringic acid, epicatechin, and rutin were

Seasonal and Within‐Day Variation on Hummingbirds Visits and Dominance Hierarchy in a Brazilian Cerrado Area

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT Plant‐hummingbird interaction networks can be influenced by environmental conditions and resources, which vary seasonally and daily. We aimed to understand how variations in these parameters across these two temporal windows influence patterns of plant‐hummingbird interactions and hummingbirds dominance hierarchies in a Brazilian Cerrado ...

Multiscale Environmental Drivers of Aquatic Insect Assemblages in Cerrado Streams

Austral Ecology, Volume 51, Issue 3, March 2026.
Multi‐scale drivers of aquatic insect communities in Cerrado streams. The gradient (from left to right) indicates increasing spatial scale, showing that abundance is influenced by local factors (conductivity, temperature), taxonomic richness responds to agricultural land use at an intermediate scale, and community composition is structured by regional ...

Fine‐Scale Genomic Divergence in the Amazonian Pirarucu (Arapaima gigas) Highlights the Need for Local Management Strategies

Freshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Freshwater habitats face significant human disturbances globally, impacting food security and ecosystems. Protected areas can mitigate biodiversity loss, but limited data on population connectivity hinders conservation management. This study examines pirarucu (Arapaima gigas), a heavily exploited and threatened Amazonian fish, using genomic ...
