ABSTRACT Given the importance of soil conditions for ecosystem functioning, fertilisation experiments are a valuable tool for assessing how systems respond to changes in soil properties. However, the effects of changes in nutrient availability on multitrophic interactions in savannah ecosystems of the Brazilian Cerrado are still scarce. We investigated

Insecticidal activity of a Melinis minutiflora grass extract on Stomoxys calcitrans flies
Several extraction methods were utilized to study the insecticidal activity of a Melinis minutiflora grass extract. Four concentrations (10, 20, 40, 80%) of the product which had the highest yield (i.e., a wax-free hexane extract) were tested to establish its insecticidal activity on S. calcitrans flies (adults and larvae).

Allelopathic hypotheses revisited: the interactions between native and exotic species in the Brazilian savanna [PDF]
We investigated allelopathic interactions between native and exotic species of the Cerrado biome. We studied the effects of the exotic Andropogon gayanus and the native A. bicornis on the initial growth of two native (A. fastigiatus and Lepidaploa aurea)

Insights on the Potential of Natural Regeneration to Restore Cerrado Open Ecosystems
The colonisation potential of native Cerrado species in degraded areas will depend on the remaining underground structures and not on seed rain from nearby conserved remnants. Effective restoration of the Cerrado will not be possible without active restoration, if the bud‐bank are not present in the system.

Burn them all? Use and efficacy of fire as a tool for grassland restoration
Grassland ecosystems have suffered significant degradation and restoring them is fundamental to fight against climate change and biodiversity loss. Fire is an important component in the evolution and management of grasslands worldwide and can potentially be used to restore grasslands. In this paper, we present a systematic literature review to know how

ABSTRACT Questions Inselbergs, isolated rock outcrops, support unique plant communities. Maritime inselbergs (MIs) experience transient isolation due to maritime fluctuations, creating harsh survival conditions. This study is the first to investigate the plant communities' patterns on MIs, comparing them with those on continental inselbergs (CIs).

Fronteira do Gado e a Melinis Minutiflora P. Beauv. (POACEAE):
Este artigo objetiva apresentar uma revisão da bibliografia que informa sobre a introdução de gramíneas exóticas, sobretudo de origem africana, no Cerrado goiano. A pecuária foi a principal atividade econômica de Goiás no século XIX e na primeira metade do século XX. Os campos do Cerrado goiano favoreceram o assentamento de parte da sociedade rancheira
