Lychnophora pinaster in endangered campos rupestres: phenolic compounds and population ecogeography
Anais da Academia Brasileira de Ciências, 2023 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 ...

Influência das propriedades do solo sobre a abundância das espécies vegetais em campos ferruginosos no sudeste do Brasil [PDF]
, 2008 Ferruginous "campos rupestres" are a particular type of vegetation growing on iron-rich primary soils. We investigated the influence of soil properties on plant species abundance at two sites of ferruginous "campos rupestres" and one site of quartzitic ...

Histórico de incêndios em campos rupestres disjuntos
Biodiversidade Brasileira, 2022 Incêndios recorrentes representam o pior cenário de fogo para os ecossistemas naturais, pois resultam das alterações nos regimes de fogo sustentáveis dos ambientes. Informações sobre regimes atuais quase não estão disponíveis para os campos rupestres, ainda mais aqueles não protegidos legalmente, o que poderia direcionar melhores estratégias de gestão ...

Habitat heterogeneity and diversity of bryophytes in campos rupestres [PDF]
Acta Botanica Brasilica, 2017 ABSTRACT 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. Bryophytes respond rapidly and efficiently to variation in microclimate.

Environmental severity promotes phylogenetic clustering in campo rupestre vegetation [PDF]
Acta Botanica Brasilica, 2015 The stress-dominance hypothesis postulates that the importance of competition in plant communities declines with increasing environmental stress while the importance of environmental filters increases. To test this hypothesis for campo rupestre vegetation, we analyzed phylogenetic diversity and community structure of angiosperm communities at two study
