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.

EMERGENCE, INITIAL GROWTH, AND SEEDLING QUALITY OF Eremanthus incanus: SUBSIDIES FOR GENETIC BREEDING AND CONSERVATION [PDF]
Revista Árvore, 2023 So far, the commercial production of Eremanthus incanus seedlings has been performed with seeds without any genetic control. Thus, we propose two experiments to examine seed-trees' effect on their descendants via the seminal in the nursery phase and ...

Sauvagesia (Ochnaceae) in the campos rupestres of the Espinhaço Range, Brazil
Rodriguésia, 2023 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

Zooming in on quartzitic outcrops: micro-habitat influences on flora and vegetation
Rodriguésia, 2021 Rock outcrop vegetation is recognized worldwide by its singular and biodiverse flora. Campo Rupestre forms hyperdiverse mosaics in rocky environments across a wide latitudinal and altitudinal gradient, with high species turnover at macro- and micro ...

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 ...

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 ...
