Actinocephalus verae (Eriocaulaceae), a new species from the Brazilian Campos Rupestres
Brittonia, 2010We describe and illustrate the new species Actinocephalus verae (Eriocaulaceae: Paepalanthoideae). This species is endemic to the rocky outcrops of the Espinhaco range in Minas Gerais, Brazil. We make comparisons with Actinocephalus ithyphyllus and Actinocephalus ochrocephalus, the morphologically most similar species.

Ecophysiology of Campos Rupestres Plants
2016Campos 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.

Penumbral rock communities in campo rupestre sites in Brazil
Journal of Vegetation Science, 1993Abstract. A syntaxonomic study of penumbral (open‐shade) communities in small rock caves in five campo rupestre sites in Minas Gerais, Brazil, was carried out according to the Braun‐Blanquet method. On the basis of 41 releves, the following new syntaxa were described: the associations Doryopterido ornithopodis‐Eriocauletum cipoensis, Coccocypselo ...

Biogeomorphological evolution of rocky hillslopes driven by roots in campos rupestres, Brazil
Geomorphology, 2021Abstract 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

Utricularia biceps (Lentibulariaceae), a new species belonging to U. sect. Foliosa, is here described and illustrated. This new species is endemic to the campos rupestres of eastern Brazil, an extremely biodiverse and endangered vegetation. Notes on phenology, ecology, habitat, and conservation are provided, along with a discussion on the features that

Photosynthetic strategies and Phosphorus use efficiency of Asteraceae species in Campo Rupestre
2022The threatened brazilian ferruginous campo rupestre, also known as canga is a fire prone and nutrient impoverished landscape, with high diversity of functional traits. The plant species found in this environment are generally characterized as of slow growth, higher leaf mass per area (LMA) and leaf dry mass content (LDMC), limited more by phosphorus (P)
