AbstractWe investigated the effects of geographic distance and environmental heterogeneity on Asteraceae communities in the rupestrian grasslands of the Espinhaço Range, southeastern Brazil. Asteraceae species composition and relative abundance were sampled in 21–1 ha plots distributed across park conservation units, comprising an environmental ...

Abstract Plant interactions with flower visitors are essential to understand the reproductive biology, evolution and distribution of flowering plants. Morphological convergences of flower traits have allowed flowers to maximize their attraction to pollinator agents leading to the concept of pollination syndromes.

In the course of preparing a monograph of Microlicieae (Melastomataceae) for Serra do Cipó, two new species of Microlicia were discovered that are described and illustrated here. The two proposed species, Microlicia nortecipoana and Microlicia obovatifolia, are probably endemic to this mountain range.

Abstract The arbuscular mycorrhizal fungi (AMF) are important organisms with enormous potential for use in ecological restoration due to their positive association to seedlings. We evaluated the effects of soil degradation on a species-rich AMF community that could hinder the restoration of rupestrian grassland sites whose soil had been removed. Soil

Termites are key organisms in tropical soil processes, accounting for a marked role in pedobioturbation and nutrient cycling. We report on the mound-building termite effects across a representative soil/vegetation gradient in Ironstone Rupestrian Grassland (canga) in Carajas, Brazilian Amazonia.

In spite of the increasing number of studies on the Rupestrian Grassland, the knowledge generated is insufficient to promote further conservation due to the rapid pace of impacts caused by human disturbances. These disturbances include biological invasions, afforestation, mining, road construction, tourism, fire, plant extraction, cattle ranching, and ...
