ASSESSMENT OF TEXTURE FEATURES FOR BRAZILIAN SAVANNA CLASSIFICATION: A CASE STUDY IN BRASÍLIA NATIONAL PARK [PDF]
Revista Brasileira de Cartografia, 2017 Distinguishing Brazilian savanna physiognomies is an essential task to better evaluate carbon storage and potential emissions of greenhouse gases. In this study, we propose to evaluate the potential of texture features to improve the discrimination among

Spatial distribution of soil δ13C in the central Brazilian savanna
Journal of Environmental Management, 2021 Stable carbon isotope ratios (δ13C) of soil record information regarding C3 and C4 plants at the landscape scale that can be used to document vegetation distribution patterns. The Central Brazilian savanna (locally called the Cerrado) has a substantial potential to develop studies of patterns of dynamics and distribution of soil δ13C, due to its ...

Seasonal variation of ground spiders in a Brazilian Savanna [PDF]
Zoologia (Curitiba), 2010 The Brazilian Savanna Ecoregion (Cerrado) is one of the richest biomes in the world, with a characteristic highly seasonal climate a dry season between May and September and a rainy season from October through April. Ground-dwelling spiders from three Cerrado phytophysiognomies, "campo cerrado", "cerrado" and "cerrad o", were sampled using pitfall ...

Ecological phytochemistry of Cerrado (Brazilian savanna) plants [PDF]
Phytochemistry Reviews, 2013 The Cerrado (the Brazilian savanna) is one of the vegetation formations of great biodiversity in Brazil and it has experienced strong deforestation and fragmentation. The Cerrado must contain at least 12,000 higher plant species.We discuss the ecological relevance of phytochemical studies carried out on plants from the Cerrado, including examples of ...

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.
