Species Distribution Modeling Reveals Future Climate Refugia and Important Areas for Rocky Plants in Brazil's Iron Quadrangle. [PDF]

Ecol Evol
Climate change is projected to sharply reduce suitable habitats for eight endemic rupestrian plant species in Brazil's Iron Quadrangle. Ensemble niche models reveal species‐specific vulnerabilities and highlight climatic refugia and corridors that may support persistence.

Modifications in fire frequency impact belowground plant components in old-growth grasslands, posing risks to their resilience. [PDF]

Am J Bot
Abstract Premise In edaphic old‐growth grasslands, the low nutrient content of the soil restricts plant species establishment. Additionally, fire remains an important factor in shaping vegetation structure and belowground biomass investment in old‐growth grasslands, such as the campos rupestres.

Modeling Climate Change Impacts on a Socioeconomically Vital Plant: The Case of <i>Comanthera elegans</i> (Goldenfoot Flower). [PDF]

Ecol Evol
Comanthera elegans, an ecologically important species in rocky grasslands, is projected to face significant habitat loss under future climate change scenarios. Modeling with the Maxent algorithm showed that its suitable habitats, defined by high rainfall seasonality and moderate temperatures, are at risk, especially under high greenhouse gas emissions.

Lithobiomes Heterogeneity and Geographic Distance Shape the Landscape Genomics Within Brazilian Mountain Systems. [PDF]

Ecol Evol
Genomic analyses of Paepalanthus calvus across Brazilian montane ecosystems reveal strong population structure shaped by geographic distance and lithological heterogeneity. Fine‐scale edaphoclimatic factors are the main predictors of genetic divergence among distinct lithobiomes, underscoring the role of substrate‐driven ecological isolation and local ...

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna. [PDF]

Biol Rev Camb Philos Soc
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 ...
