13. Distribution extension of Phimophis guerini (Serpentes: Dipsadidae: Xenodontinae) in the Brazilian Amazon
ABSTRACT Phimophis guerini Duméril, Bibron & Duméril, 1854 is a Xenodontinae snake distributed in Argentina, Brazil and Paraguay. In Brazil, the species is broadly distributed, occurring mainly in open areas of the Cerrado, but also in the Amazon, Atlantic forest and Caatinga. We provide a new record for this species from the municipality of Santarém in t

14. Climate Change Influencing the Potential Distribution of a Brazilian Savanna Indicator Species
ABSTRACT The objective of this study was to model the potential effect of future climate change on the distribution of a tree species indicator of Cerrado. For the modeling, we used 488 occurrence points of the species and also bioclimatic variables corresponding to 2050 and 2070, for the more optimistic and pessimistic scenarios. All generated models were c

15. Edaphic Filters and Plant Colonization in a Mine Revegetated with Sewage Sludge
ABSTRACT We evaluated the recruitment of plant species and their relation with edaphic attributes in a mine revegetated with sewage sludge in the Brazilian Federal District. Plant species in the revegetated mine and in remaining portions of Cerrado (savanna) within the mined landscape were sampled and identified. Then, samples of revegetated substrate and so

16. Vegetative propagation of pequi (souari nut) by cutting
RESUMO: O pequizeiro é propagado predominantemente por via seminal apresentando germinação desuniforme e reduzida. A crescente demanda por frutos e mudas para reflorestamento indicam a necessidade de novas estratégias para a propagação desta espécie, minimizando os impactos do extrativismo predatório. Objetivou-se com este estudo auxiliar no desenvo

17. Sugarcane Root Development and Yield under Different Soil Tillage Practices
ABSTRACT New strategies for sugarcane production have been very important since the incorporation of ethanol in the Brazilian energy mix in the early 1970s. Prior to planting sugarcane, the soil is prepared, and this process can affect root development and, consequently, sugarcane production. This study was conducted in an area of sugarcane crop renewal in t

18. Reproductive phenology differs between evergreen and deciduous species in a Northeast Brazilian savanna
ABSTRACT Evergreen (EG) and deciduous (DEC) species exhibit distinct strategies to overcome dry periods and achieve adequate water status for reproduction and growth. Such particularities may result in distinct reproductive strategies between these groups. Thus, we evaluated the phenology of EG and DEC groups, comparing and differentiating their reproductive

19. Hydropedology of a High Tableland with Cerrado, Brazilian Central Plateau: the Frutal Catchment Case Study
ABSTRACT: Currently, the Brazilian savanna (Cerrado) represents the main agricultural area of the country, comprising a great variety of landscapes and soils, geological formations and vegetation patterns, as well as the major watershed. We studied the hydropedology and morphometry of a representative catchment (Frutal river), on a high tableland (Chapada) i

20. Nutrient cycling between soil and leaf litter in the Cerrado (Brazilian savanna) on eutrophic and dystrophic Neosols
ABSTRACT We evaluated nutrient cycling by measuring leaf litter production and decomposition in the Brazilian savanna (cerrado sensu stricto) on eutrophic (calcareous) and dystrophic (arenitic) Neosols over the same spatiotemporal scale. We installed three transects in the Cerrado with plots in each Neosol type. Areas along the transects were randomly chosen

21. Nest architecture development of grass-cutting ants
ABSTRACT Atta bisphaerica is a species of grass-cutting ants commonly found in the Cerrado biome. The Brazilian Cerrado (savanna) biome covers 2 million km representing 23% of the area of the country. It is an ancient biome with rich biodiversity, estimated at 160,000 species of plants, fungi and animals. However, little is known about their nest architectur

22. BRS 368RF: A glyphosate tolerant, midseason upland cotton cultivar for Northeast and North Brazilian cerrado
Abstract Cotton cultivar BRS 368RF was developed by EMBRAPA in a partnership with the Bahia Foundation, aiming to create high-yielding germplasm by adding transgenic traits addressed to Brazilian Savanna (cerrado) of the Northeast and North regions. BRS 368RF is a midseason cultivar and has yield stability and transgenic tolerance to glyphosate.

23. Fungal Community Structure as an Indicator of Soil Agricultural Management Effects in the Cerrado
ABSTRACT Forest-to-agriculture conversion and soil management practices for soybean cropping are frequently performed in the Cerrado (Brazilian tropical savanna). However, the effects of these practices on the soil microbial communities are still unknown. We evaluated and compared the fungal community structure in soil from soybean cropland with soil under n

24. Leaf anatomical traits of non-arboreal savanna species along a gradient of tree encroachment
ABSTRACT In the Brazilian savanna (Cerrado of Brazil), fire suppression has transformed typical savanna formations (TS) into forested savanna (FS) due to the phenomenon of encroachment. Under encroachment, non-arboreal plants begin to receive less light due to greater tree density and canopy closure. Here we aim to evaluate if leaf anatomical traits of non-a
