Angiosperm disjunction "Campos rupestres - restingas": a re-evaluation Disjunção de Angiospermas Campos Rupestres - Restingas: uma reavaliação [PDF]

Acta Botânica Brasílica, 2007
A disjunct distribution pattern between the extrazonal formations of the campos rupestres (rocky grasslands) in the Espinhaço mountain range and the restingas (coastal strand vegetation) in Brazil has been proposed repeatedly for several flowering-plant ...

Habitat heterogeneity and diversity of bryophytes in campos rupestres [PDF]

Acta Botânica Brasílica, 2017
Campos rupestres (rupestrian grasslands) are characterized by the presence of rock outcrops associated with an herbaceous-shrub physiognomy typically growing on quartzitic soils; they occur a wide variety of habitats.

Microbiomes of Velloziaceae from phosphorus-impoverished soils of the campos rupestres, a biodiversity hotspot. [PDF]

Sci Data, 2019
AbstractThe rocky, seasonally-dry and nutrient-impoverished soils of the Brazilian campos rupestres impose severe growth-limiting conditions on plants. Species of a dominant plant family, Velloziaceae, are highly specialized to low-nutrient conditions and seasonal water availability of this environment, where phosphorus (P) is the key limiting nutrient.

Plant Biodiversity Drivers in Brazilian Campos Rupestres: Insights from Phylogenetic Structure. [PDF]

Front Plant Sci, 2017
Old, climate-buffered infertile landscapes (Ocbils) have attracted increasing levels of interest in recent years because of their exceptionally diverse plant communities. Brazil's campos rupestres (rupestrian grasslands) are home to almost 15% of Brazil's native flora in less than 0.8% of Brazil's territory: an ideal study system for exploring ...

Ecophysiology of Campos Rupestres Plants

, 2016
Campos rupestres are rocky seasonally-dry environments that occur over mountaintops in central Brazil. Plant growth is limited and prone to fire during the dry winter, and soils are severely nutrient-impoverished. Plants in these habitats exhibit a wide range of strategies to cope with these limitations.
