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

Ecology and Evolution
Lithological heterogeneity, climatic gradients, and geographic distance may shape the genetic structure of montane plant species, but their combined effects remain underexplored in Neotropical ecosystems.

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.

Fine-tuning the buzz: comparing visitation frequency and pollination effectiveness in plant-pollinator networks. [PDF]

New Phytol
Summary Ecological network approaches have advanced our understanding of how species interactions influence community and evolutionary dynamics. However, a key limitation is that most network analyses rely solely on visitation data, often overlooking functional aspects of interactions.

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 ...
