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

Complete mitochondrial genome sequence of Myrmecophaga tridactyla from Brazilian Savanna. [PDF]
Mitochondrial DNA B Resour, 2018 Myrmecophaga tridactyla, popularly known as giant anteater, is a member of Xenarthra magnorder which is under the threat of extinction. Herein, we describe the complete mitochondrial genome of M. tridactyla. The circular DNA molecule is 16,546 bp long, contains 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and a non-coding Control Region of ...

Spatial distribution of wood volume in Brazilian savannas [PDF]
Anais da Academia Brasileira de Ciências, 2019 Here we model and describe the wood volume of Cerrado Sensu Stricto, a highly heterogeneous vegetation type in the Savanna biome, in the state of Minas Gerais, Brazil, integrating forest inventory data with spatial-environmental variables, multivariate regression, and regression kriging.

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 ...

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.

Phylogenetic overdispersion of plant species in southern Brazilian savannas [PDF]
Brazilian Journal of Biology, 2009 Ecological communities are the result of not only present ecological processes, such as competition among species and environmental filtering, but also past and continuing evolutionary processes. Based on these assumptions, we may infer mechanisms of contemporary coexistence from the phylogenetic relationships of the species in a community.

Can our current knowledge and practice allow ecological restoration in the Cerrado?
Anais da Academia Brasileira de Ciências, 2022 Ecological knowledge plays a significant role in ensuring efficient ecological restoration. We conducted a systematic review to assess if sufficient ecological knowledge has been accumulated to aid restoration practices for the Cerrado, a Brazilian biome
