Phenology is the study of recurrent biological events in the life cycle of organisms. For plants, reproductive events such as flowering and fruiting are critical stages in their life cycles, which also greatly affect other ...

Mountains are interesting systems for studying patterns of diversity distribution and the role of environmental filters and competition on community assembly. According to the phylogenetic niche conservatism theory, the ...

Aim: Climate tends to explain phenological variations in tropical ecosystems. However, water availability and nutrient content in soil strongly affect plant communities, especially those on old, climatically buffered, ...

The vegetation of ironstone rupestrian grasslands (canga) is of significant conservation concern due to the rapid encroachment of mining activity and urbanization on the remnants of this ecosystem. Ecological studies that ...

Rupestrian grasslands are biodiverse, evolutionary old vegetation complexes that harbor more than 5000 species of vascular plants and one of the highest levels of plant endemism in the world. Growing on nutrient–impoverished ...

Campo rupestre is a megadiverse vegetation mosaic dominating one of the world's geologically oldest tropical mountains. The campo rupestre hosts nearly 15% of Brazil's flora, with 40% of endemism in an area smaller than ...

The campo rupestre is a unique mountaintop ecosystem in eastern South America, recognised for its endemism and as ecological refugia for plant and animal taxa. Multiple clades of frogs are represented in the Brazilian campo ...

Mining causes profound impacts on biodiversity. In Brazil, mining pressure is intense, especially in highly biodiverse regions such as the Espinhaço range. We analyzed the direct and indirect effects of mining on the ...
