Monitoring Effect of Fire on Ant Assemblages in Brazilian Rupestrian Grasslands: Contrasting Effects on Ground and Arboreal Fauna [PDF]

Insects, 2017
Fire is one of the most relevant ecological disturbances in nature. Little is known about the effects of fire on biodiversity in ecosystems like rupestrian grasslands, which share characteristics with savanna and forest biomes.

Few Ant Species Play a Central Role Linking Different Plant Resources in a Network in Rupestrian Grasslands. [PDF]

PLoS ONE, 2016
Ant-plant associations are an outstanding model to study the entangled ecological interactions that structure communities. However, most studies of plant-animal networks focus on only one type of resource that mediates these interactions (e.g, nectar or ...

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Growing Periandra mediterranea on post-mining substrate: native Fabaceae with potential for revegetation of degraded rupestrian grasslands in Brazil

Acta Botanica Brasilica, 2018
Recovery of degraded areas of rupestrian grasslands is hampered mainly by the limited knowledge regarding substrate management and the biology of native species suitable for revegetation of these areas.
