| The high tree diversity and vast extent of Amazonian forests challenge our understanding of how tree species abundance and composition varies across this region. Information about these parameters, usually obtained from tree inventories plots, is essential for revealing patterns of tree diversity. Numerous tree inventories plots have been established in Amazonia, yet, tree species composition and diversity of white-sand and terra-firme forests of the upper Rio Negro still remain poorly understood. Here, we present data from eight new one-hectare tree inventories plots established in the upper Rio Negro; four of which were located in white-sand forests and four in terra-firme forests. Overall, we registered 4703 trees > 10 cm of diameter at breast... |

| The taxonomy of the genus Campylorhamphus Bertoni, 1901 is still uncertain, with many inconsistent evolutionary patterns implied by current taxonomy. A re-analysis of the type-series of Campylorhamphus procurvoides successor Todd, 1948 revealed that the holotype is indistinguishable from Campylorhamphus trochilirostris notabilis Zimmer, 1934, while the paratypes belonged either to the latter taxon or to a second already named taxon (Campylorhamphus trochilirostris snethlageae Zimmer, 1934), and a third and yet undescribed taxon allied to Campylorhamphus procurvoides. Here, we present statistical analyses of morphological data supporting the synonymization of C. p. successor into C. t. notabilis, the name with priority. Our findings resolve the... |
