We calculated all three diversity attributes using Hill numbers: q = 0 (richness), q = 1 (richness weighted by relative abundance), and q = 2 (richness weighted by dominance). 5,000 woody plant individuals in 50 plots of 0.1 ha located in five terra firme forest sites spread over a latitudinal gradient of 1200 km covering ca. 1,250 species, and obtained functional trait records for ca. In this study we aimed: 1) to investigate the relationships between all three diversity attributes, i.e., taxonomic diversity (TD), functional diversity (FD), and phylogenetic diversity (PD) 2) to quantify the latitudinal variation in these diversity attributes in western Amazonian terra firme forests and 3) to understand how climatic and edaphic drivers contribute to explaining diversity patterns. 7Departamento de Manejo Forestal, Universidad Nacional Agraria La Molina, Lima, PeruĮlucidating how environmental factors drive plant species distributions and how they affect latitudinal diversity gradients, remain essential questions in ecology and biogeography.6Departamento de Ciencias Agrarias, Universidad Científica del Sur, Villa el Salvador, Peru.5School of Geography and Environment, University of Oxford, Oxfordshire, United Kingdom.4Sección Quíımica, Pontificia Universidad Católica del Perú, Lima, Peru.3Centro de Investigación en Biodiversidad y Cambio Global (CIBC-UAM), Universidad Autónoma de Madrid, Madrid, Spain.2Departmento de Biología y Geología, Física y Química Inorgánica, Universidad Rey Juan Carlos, Móstoles, Spain.
