Exploring the mycobiota of bromeliads phytotelmata in Brazilian Campos Rupestres. [PDF]
Braz J Microbiol, 2023 The phytotelmata is a water-filled tank on a terrestrial plant, and it plays an important role in bromeliad growth and ecosystem functioning. Even though previous studies have contributed to elucidate the composition of the prokaryotic component of this aquatic ecosystem, its mycobiota (fungal community) is still poorly known. In the present work, ITS2

Biogeomorphological evolution of rocky hillslopes driven by roots in campos rupestres, Brazil
Geomorphology, 2021 Abstract The campos rupestres (rocky grassland) comprise an old-growth seasonally dry herbaceous ecosystem on mountaintops in central and eastern Brazil and in disjoint areas with sparse shrubs with high plant diversity and endemism. This ecosystem consists of sharp-edged quartzite landforms and rocky hillslopes with boulders, blocks, and sparse soil

Ants in Burned and Unburned Areas in Campos Rupestres Ecosystem
Sociobiology, 2016 Ground-dwelling ants have shown consistent resilience to fire in savanna environments. We carried out a study to investigate how ant community structure responds to fire in a harsh and fragile Cerrado ecosystem, the campos rupestres. We studied the change in the ant communities on a local scale subjected to fire in two rocky outcrop habitats at two ...

Floristic mosaics of the threatened Brazilian campo rupestre
Nature Conservation Research, 2022 The increase in rates of habitat loss requires an understanding of how biodiversity is distributed. Campo rupestre is an old, climatically buffered, and infertile landscape located in Brazil. Considered a biodiversity hotspot, the campo rupestre is mainly threatened by mining activity that requires a large operating area.

EXTENDING THE LIMITS OF CAMPOS RUPESTRES IN BRAZIL
Caminhos de Geografia, 2021 Campos rupestres are typical ecosystems of rock outcrops with high biodiversity and endemism, located in Brazilian territory, with vegetation analogous in Africa and Australia. The campos rupestres cover deeply dystrophic soils on highlands inserted in Amazon rainforest, Atlantic rainforest and Cerrado biomes. Despite recognition of campos rupestres as
