Bukholderia strains promote Mimosa spp. growth but not Macroptilium atropurpureum

Revista Ciência Agronômica
The aim of this study was to evaluate the relationship and symbiotic efficiency of 14 strains of Burkholderia isolated from rupestrian grasslands, using M. atropurpureum and Mimosa tenuiflora as trap plants, with the species M.

Historical Fragmentation in Atlantic Forest Explains the Diversification of a Clade of Mountaintop Bromeligenous Frogs (Leptodactylidae: Crossodactylodes)

Zoologica Scripta, Volume 54, Issue 6, Page 823-839, November 2025.
ABSTRACT The Atlantic Forest domain is a biodiversity hotspot with remarkable amphibian diversity, including over 700 species, 70% of which are endemic. Most of these endemic species have restricted geographic ranges, often confined to mountainous areas, as exemplified by the leptodactylid genus Crossodactylodes.

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

, 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.

Neighbourhood flower diversity increases reproductive success of Lantana hypoleuca Briq (Verbenaceae)

Plant Biology, Volume 27, Issue 6, Page 1158-1164, October 2025.
A neighbourhood plant richness increases reproductive success. Abstract The attraction of floral visitors depends on intrinsic plant traits and the surrounding floral abundance and diversity. Therefore, it is important to consider the conspecific and heterospecific co‐flowering context to understand plant–pollinator interactions and, consequently ...

Floral Traits and Breeding Systems in Sincoraea (Bromeliaceae), an Endemic Genus of Brazilian Rupestrian Grasslands

Plants
Brazilian campos rupestres are a global center of plant endemism, but they are increasingly threatened by climate change and human activities. In this context, Sincoraea, an endemic genus of the Espinhaço Mountain Range, provides an important model for ...

Changes in Vegetation Cover and Their Effects on the Diversity of Fruit‐Feeding Butterflies

Austral Ecology, Volume 50, Issue 7, July 2025.
We used fruit‐feeding butterfly diversity as a bioindicator of deforestation for implementing pastures in Brazilian tropical dry forests. A total of 1091 individuals belonging to 35 species of the Nymphalidae family were sampled. Changes in land cover and tree density were important factors in explaining butterfly diversity.

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

Acta 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.

Habitat heterogeneity and diversity of bryophytes in campos rupestres

Acta 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.
