Endophytic fungi in roots of native orchids of rupestrian grasslands (campos rupestres) in Serra do Cipó, Brazil

open access: yesIheringia, Série Botânica, 2021
Root endophytic fungi are essential to the life cycle of orchids. Many of them act as growth promoters of the host plant and mycorrhizal endophytes are indispensable to seed germination. This study aimed to evaluate the cultivable endophytic fungal richness of five native orchids of rupestrian grasslands (campos rupestres) in Serra do Cipo, Brazil ...

Ornamental potential of species from the ferruginous Campo rupestre of the Carajás National Forest, Brazilian Amazon [PDF]

open access: yes, 2020
The flora of the ferruginous Campo rupestre that occur over the immense iron deposits of the Carajás National Forest is very unique, with several endemic and rare species. This vegetation is directly affected by mining activity, as a result of vegetation

Post-fire resprout in an endangered and narrow endemic shrub from rupestrian grasslands, Serra do Cipó, southeastern Brazil [PDF]

open access: yes, 2017
Embora existam evidências de que a vegetação dos campos rupestres seja resiliente à passagem do fogo, são incipientes as investigações sobre os efeitos da crescente frequência de incêndios de origem antrópica em plantas raras e endêmicas desse ...

Effects of sex and altitude on nutrient, and carbon and nitrogen stable isotope composition of the endangered shrub Baccharis concinna G.M. Barroso (Asteraceae)

open access: yesActa Botânica Brasílica
Previous ecological studies of dioecious plant species have found that female plants preferentially occur at lower altitudes where there are typically better nutritional conditions, while male plants often occur in less favorable sites.

Effect of depth, seasonality and light on a soil seed bank of rupestrian grassland

open access: yes, 2022
The floristic composition of the rupestrian grasslands comprises a mosaic of species with different adaptations exhibiting high diversity and endemism. However, the plant species from rupestrian grasslands are dependent on site-specific conditions and their reproduction is almost always limited, making natural regeneration after disturbances difficult.

Habitat heterogeneity and diversity of bryophytes in campos rupestres

open access: yesActa Botânica Brasílica
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.

Áreas prioritárias e conectividade funcional multiespécie: dos processos metodológicos às prioridades de conservação [PDF]

open access: yes, 2023
Landscapes with greater connectivity are essential to minimize biodiversity losses. In this work, we present a methodological proposal for the definition of Priority Areas for Conservation (PACs) through multispecies functional connectivity, developed in
