Oxyfluorfen bioavailability in Brazilian Savanna soils
Pesquisa Agropecuária Tropical, 2022 Oxyfluorfen is a pre-emergent herbicide applied via soil; however, the soil attributes have not been considered to predict the herbicide doses. This study aimed to evaluate the bioavailability of the oxyfluorfen herbicide in Brazilian Savanna soils with ...

Ant pollination of Paepalanthus lundii (Eriocaulaceae) in Brazilian savanna. [PDF]
Ann Bot, 2019 Abstract Background and Aims Ant–plant associations are widely diverse and distributed throughout the world, leading to complex ecological networks. Regarding ant–plant mutualism, ant pollination is a very rare interaction and few studies have shown the role of ants as pollinators. Therefore, we aimed

Unmasking the architecture of ant-diaspore networks in the Brazilian Savanna. [PDF]
PLoS One, 2018 Ant-diaspore interactions are directly related to fruit consumption, seed predation and dispersal, being determinant for the plant fitness. However, although abundant and diversified, these ecological interactions have been neglected in network studies.

Ammonia oxidisers in a non-nitrifying Brazilian savanna soil [PDF]
FEMS Microbiology Ecology, 2017 Low nitrification rates in Brazilian savanna (Cerrado) soils have puzzled researchers for decades. Potential mechanisms include biological inhibitors, low pH, low microbial abundance and low soil moisture content, which hinders microbial activity, including ammonia oxidation.

Landsat phenological metrics and their relation to aboveground carbon in the Brazilian Savanna. [PDF]
Carbon Balance Manag, 2018 Background The quantification and spatially explicit mapping of carbon stocks in terrestrial ecosystems is important to better understand the global carbon cycle and to monitor and report change processes, especially in the context of international policy mechanisms such as REDD+ or the implementation of Nationally Determined Contributions (NDCs) and ...

Seasonal effects in a lake sediment archaeal community of the Brazilian Savanna. [PDF]
Archaea, 2014 The Cerrado is a biome that corresponds to 24% of Brazil’s territory. Only recently microbial communities of this biome have been investigated. Here we describe for the first time the diversity of archaeal communities from freshwater lake sediments of the Cerrado in the dry season and in the transition period between the dry and rainy seasons, when the
