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

Biosilicification in monocots: Comparative analysis highlights contrasting patterns of deposition. [PDF]
Am J BotAbstract Premise New insights into biomineral uptake and sequestration are important for understanding how plants grow. Some plants accumulate silica accretions in precise locations in particular cells. Among monocots, controlled biosilicification occurs in several different forms and is restricted to commelinids and orchids. Methods We utilized energy‐
