Mapping density, diversity and species-richness of the Amazon tree flora.
Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree species-richness at 0.1-degree resolution, and investigated drivers for diversity and richness. Using only location, stratified by forest type, as predictor, our spatial model, to the best of our knowledge, provides the most... -

Checklist of Orchidaceae from Caquetá, Colombia.
A checklist of Orchidaceae from Caquetá, Colombia is presented here. We recorded 98 genera and 418 species, exceeding a previous inventory by 276 species. The checklist is conservative in the number of genera and species by including only taxa that were fully and reliably identified and that are either linked... -

Unraveling Amazon tree community assembly using Maximum Information Entropy: a quantitative analysis of tropical forest ecology.
In a time of rapid global change, the question of what determines patterns in species abundance distribution remains a priority for understanding the complex dynamics of ecosystems. The constrained maximization of information entropy provides a framework for the understanding of such complex systems dynamics by a quantitative analysis of important... -

Hydro-Edaphic Gradient and Phylogenetic History Explain the Landscape Distribution of a Highly Diverse Clade of Lianas in the Brazilian Amazon.
Plant distribution patterns may indicate habitat specialization either by closely related species with conserved traits or by phylogenetically distant species with converging traits. Lianas represent a large proportion of the overall tropical species diversity and abundance. Despite their importance, little is known about the relationship between habitat specialization and the... -

Eriocaulaceae in the Brazilian Amazon and the use of Species Distribution Modelling in its conservation.
Abstract Following a survey in herbaria in Brazil and abroad, complemented by a survey of the literature and searches of biodiversity data, 66 taxa of Eriocaulaceae have been identified in the Brazilian Amazon, as defined by the states of Acre, Amapá, Amazonas, Pará, Rondônia and Roraima. Six genera of Eriocaulaceae...Potential geographic distribution modeling, Geographical distribution, Species conservation, Eriocaulaceae, Brazil, and Amazon

Flora das cangas da Serra dos Carajás, Pará, Brasil: história, área de estudos e metodologia.
Resumo No final da década de 1960, pesquisadores do Museu Paraense Emílio Goeldi (MPEG) iniciaram as coletas botânicas na Serra dos Carajás, resultando em um expressivo acervo e interessantes descobertas sobre a flora local, marcada por endemismos e pressão por atividades mineradoras. Em 2014, foi estabelecido o projeto "Flora das...Ironstone savannas, Campos rupestres, Brazil, Pará (Brazil), Amazon, Taxonomy, Floristics, and Serra dos Carajás (Brazil)

Edaphic Endemism in the Amazon: Vascular Plants of the canga of Carajás, Brazil.
Amazonia is one of the most diverse biomes worldwide, and, as well as luxuriant forest, it includes mountain areas which, despite their small surface area, display fascinating endemism. In these regions, the specificity of edaphic factors is mirrored by a highly specialised, isolated flora adapted to survive adverse conditions. The...Iron-ore formations, Amazon Rainforest, Campo rupestre, Brazil, Carajás (Brazil), Conservation priorities, Amazon, Rarity, and Brazilian flora

Three new species of Myrcia sect. Myrcia (Myrtaceae) from South America.
Three new species of Myrcia are described, illustrated and discussed. Myrcia rionegrensis from the Brazilian Amazon is related to M. clusiifolia from which it differs in having leaves with acute apex and ribbed fruits (vs. rounded apex and smooth fruits in M. clusiifolia); Myrcia microcalyx is similar to Myrcia scytophylla...Lima Dos Santos, Leidiana ; Vasconcelos, Thaís N.C. ; Ferreira de Sales, Margareth ; Lucas, Eve
