Seasonal bacterial profiles of Vellozia with distinct drought adaptations in the megadiverse campos rupestres. [PDF]
Microbial communities can vary as a function of seasonal precipitation and the phenotypic characteristics of the prevailing plant species in an ecosystem. The Brazilian campos rupestres (CRs) host a unique flora adapted to harsh conditions, including severe droughts and nutrient-poor soils.

Plotting a future for Amazonian canga vegetation in a campo rupestre context. [PDF]
In order to establish effective conservation strategy, drivers of local and regional patterns of biodiversity need to be understood. The composition of local biodiversity is dependent on a number of factors including evolution and redistribution of lineages through dispersal and environmental heterogeneity.

Circumscribing campo rupestre – megadiverse Brazilian rocky montane savanas [PDF]
Currently campo rupestre (CR) is a name accepted and used internationally by botanists, zoologists, and other naturalists, usually applied to a very specific ecosystem, despite the lack of a consensual published circumscription. We present a tentative geographic circumscription of the term, combining data on climate, geology, geomorphology, soil, flora,

Sauvagesia (Ochnaceae) in the campos rupestres of the Espinhaço Range, Brazil
Abstract The campos rupestres (rupestrian grasslands) of the Brazilian Espinhaço Range are renowned for harboring extraordinary plant diversity and endemism, yet many groups representative of this habitat remain taxonomically understudied. Sauvagesia, a predominantly neotropical genus of Sauvagesieae (Ochnaceae), is a classic example. In this study, we

Lychnophora pinaster in endangered campos rupestres: phenolic compounds and population ecogeography
Lychnophora pinaster, known as arnica-mineira, is endemic to campos rupestres, at risk of extinction. The present study aimed to characterize the ecogeography and phenolic constituents of 11 L. pinaster populations collected in the mesoregions North, Jequitinhonha, Metropolitan of Belo Horizonte and Campos das Vertentes in the state of Minas Gerais ...
