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.

Phytoplankton beta diversity along cascade reservoirs of the Tocantins River is shaped by reservoir age, spatial arrangement, and environmental conditions. Younger, distant reservoirs show higher diversity, while intermediate ones tend toward homogenization. Environmental and spatial drivers differentially influence taxonomic and functional composition.
