Impactos potenciais das alterações no Código Florestal sobre a vegetação de campos rupestres e campos de altitude
article+bn04310042010. Abstract: The Brazilian campos rupestres and campos de altitude are characterized by mosaics of vegetation types and are better represented above 900 m in the Espinhaço Range and above 1500-2000 m in the Serra do Mar and Serra da Mantiqueira. They bear high species richness at local and regional scales and numerous relicts and endemisms. These montane refuges, which are o...
متن کاملPlant Biodiversity Drivers in Brazilian Campos Rupestres: Insights from Phylogenetic Structure
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 variation in floristic diversity and phylogenetic s...
متن کاملVascular plant community composition from the campos rupestres of the Itacolomi State Park, Brazil
Camposrupestres are rare and endangered ecosystems that accommodate a species-rich flora with a high degree of endemism. Here, we make available a dataset from phytosociological surveys carried out in the Itacolomi State Park, Minas Gerais, southeastern Brazil. All species in a total of 30 plots of 10 x 10 m from two study sites were sampled. Their cardinality, a combination of cover and abunda...
متن کاملDifferential Metabolic and Biological Profiles of Lychnophora ericoides Mart. (Asteraceae) from Different Localities in the Brazilian “campos rupestres”
Este artigo descreve a caracterização por CLAE-DAD-EM/EM e CLAE-DEC dos perfis de metabólitos secundários de extratos das folhas de Lychnophora ericoides Mart. de diferentes procedências e suas propriedades citotóxicas e antioxidantes. Extratos foliares de populações representando sete diferentes localidades foram avaliados quanto à atividade antioxidante pelo sistema DPPH e à atividade citotóx...
متن کاملMorphology and anatomy of leaf mine in Richterago riparia Roque (Asteraceae) in the campos rupestres of Serra do Cipó, Brazil.
The leaf mine in Richterago riparia is caused by a lepidopteran larva (lepidopteronome). The leaves of R. riparia show campdodrome venation; the epidermis is unistratified, with stomata and glandular trichomes in adaxial and abaxial surfaces. The mesophyll is bilateral and the vascular system is collateral. During the formation of the mine, the larva consumes the chlorenchyma of the mesophyll a...
