Evaluation of the antifungal potential of Brazilian Cerrado medicinal plants [PDF]

Mycoses, 2009
SummaryTherapeutic limitations, development of fungal drug resistance, drug‐related toxicity, drug interactions and insufficient bioavailability of the currently available antifungal drugs have made the development of drugs necessary that would be able to treat the emerging fungal infections. The Cerrado is the second greater biome of Brazil and it was

CO2 Fluxes and Soil Responses to Straw and Herbicide in Peanut

Land Degradation &Development, EarlyView.
ABSTRACT Peanut cultivation plays an important agronomic role in Brazil, especially in rotation with sugarcane, promoting biological nitrogen fixation and improving soil quality. This study aimed to test the hypothesis that the combined use of sugarcane mulch, peanut cultivation, and herbicide application would affect soil CO₂ fluxes, soil chemical ...

Urochloa decumbens Has Higher Mycorrhizal Colonization in Degraded than in Pristine Areas in the Brazilian Cerrado

Floresta e Ambiente, 2019
Brazil has extensive degraded areas, where vegetation fails to establish due to harsh soil conditions. However, some invasive species such as Urochloa decumbens are successful pioneers in such areas, but the reasons deserve investigation.

Spatiotemporal Fire Patterns and Post‐fire Forest Change in Peru (2000–2021)

Land Degradation &Development, EarlyView.
ABSTRACT Fire is increasingly more frequent and severe in many tropical regions, leading to significant forest loss, diminished biodiversity, and reduced Nature's contributions to people (NCPs). In this study, we analyzed the spatiotemporal patterns of fire in Peru and its regions, focusing on: (1) burned area, (2) size, and (3) number of fires, using ...

Seasonal variation of the major secondary metabolites present in the extract of Eremanthus mattogrossensis Less (Asteraceae: Vernonieae) leaves

Química Nova, 2012
The species Eremanthus mattogrossensis, known as "veludo do cerrado" (cerrado velvet), is native to the Brazilian Cerrado. Because the amount of metabolites present in plants may be influenced by biological and environmental factors, here we conducted an

Physiological ecology of cerrado plants: new insights and new approaches [PDF]

Brazilian Journal of Plant Physiology, 2008
ABSTRACT ; This special issue of the Brazilian Journal of Plant Physiology provides new insights into how cerrado plants cope with various demands imposed by the environment. They also explore the mechanisms of physiological adaptations at different scales and draw attention to the importance of phenotypic plasticity in plant adaptation to the cerrado ...

Application of Principal Component Analysis and Probabilistic Neural Networks in Ferralsols Recovery Evaluation Through Planting of Mabea Fistulifera and Eucalyptus Urograndis

Land Degradation &Development, EarlyView.
ABSTRACT This study presents an innovative assessment model for analyzing the evolution of degraded soils subjected to different reclamation strategies. The proposal combines statistical and artificial intelligence tools to jointly integrate multiple physical and chemical soil properties, allowing for a more synthetic view of the processes.

Taxonomy and diversity of Marcgraviaceae, north of the São Francisco river, northeast Brazil

Nordic Journal of Botany, EarlyView.
This study provides a comprehensive assessment of Marcgraviaceae species diversity north of the São Francisco river in northeastern Brazil, analyzing species richness and distribution patterns across 384 000 km² of phytogeographic domains. Through field collections, herbarium studies (both physical and digital), and detailed morphological analyses, we ...

First report of Acutaspis oliveirai (Lepage & Giannotti, 1942) (Hemiptera: Diaspididae) in Central Brazil: occurrence on Myrsine guianensis (Aubl.) Kuntze (Primulaceae) in the Brazilian Cerrado

Entomological Communications
 Recent research shows that the Cerrado has a great diversity of scale insects (Insecta: Hemiptera: Coccomorpha) in association with native plants. This work aimed to report the occurrence of Acutaspis oliveirai (Lepage & Giannotti, 1942) (Hemiptera ...

The relative roles of in situ diversification and lineage dispersal underlying diversity patterns at the assemblage level

Oikos, EarlyView.
Speciation, extinction, and dispersal are the historical processes influencing the spatial distribution of lineages and strongly influence diversity patterns. Here, we apply a recently developed methodological approach to quantify the relative legacies in situ diversification history (i.e.
