Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna

open access: yesBiological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Testing a General Theory for Optimal Flowering Time in Deciduous Perennial Plants as a Function of Growing Season Length

open access: yesEcology Letters, Volume 29, Issue 2, February 2026.
Climate change affects both the start and duration of growing seasons, creating complex effects on optimal flowering timing that go beyond simple responses to earlier springs. Using optimal energy allocation theory, we found a nonlinear relationship between growing season length and optimal flowering time which was supported by two experiments with ...

Beyond the Highlands: Climate Drives Evolutionary Connections Between Ancient Neotropical Mountains and Lowland Biomes

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 2, February 2026.
ABSTRACT Aim The assembly of montane plant communities through time is underlain by historical and abiotic factors. However, the extent of evolutionary connectivity between ancient highland ecosystems and surrounding lowlands remains unclear. Here, we investigate the evolutionary connections between the campos rupestres, a hyperdiverse and fragmented ...

Antioxidant Activity and Potential Cholesterol Modulating Effect of Punica granatum L. Peel Hydroethanolic Extract

open access: yesChemistry &Biodiversity, Volume 23, Issue 1, January 2026.
Punica granatum peel extract is rich in phenolic compounds, exhibits strong antioxidant activity, and modulates the expression of PCSK9 and LDL receptors. Collectively, these findings suggest a potential cardioprotective effect of the extract. ABSTRACT Lipoprotein metabolism is regulated by several key proteins, notably proprotein convertase subtilisin/
