Geological control of floristic composition in Amazonian forests
The findings suggest that Amazonian forests are partitioned into large-area units on the basis of geological formations and their edaphic properties, and the evolution of these units through geological time may provide a general mechanism for biotic diversification in Amazonia. Expand
Comparing composition and diversity of parasitoid wasps and plants in an Amazonian rain-forest mosaic
Local species richness and between-site similarity in species composition of parasitoid wasps were correlated with those of four plant groups in a western Amazonian lowland rain forest mosaic, lending only weak support to the idea of using plant distributions as indicators of animal distributions.

Forest classification in an Amazonian rainforest landscape using pteridophytes as indicator species
Habitat classification systems are poorly developed for tropical rainforests, where extremely high plant species richness causes numerous methodological difficulties. We used an indicator speciesExpand
Discovering floristic and geoecological gradients across Amazonia
AIM: To map and interpret floristic and geoecological patterns across the Amazon basin by combining extensive field data with basin‐wide Landsat imagery and climatic data. LOCATION: Amazonia. TAXON:Expand
Species richness and diversity along edaphic and climatic gradients in Amazonia
The authors' results conformed to the proposal that site productivity promotes species diversity, and seemed to arise from larger species pools on more fertile soils and in wetter climates, even when it could be expected that the older and more widespread infertile soils would have provided more opportunities for speciation.

Newly discovered diversity in the tropical fern genus Metaxya based on morphology and molecular phylogenetic analyses
SummaryFor a long time, the genus Metaxya was treated as monotypic with a single species, M. rostrata. A second species, M. lanosa, was described in 2001 on the basis of morphological features andExpand
Multispectral canopy reflectance improves spatial distribution models of Amazonian understory species
Species distribution models are required for the research and management of biodiversity in the hyperdiverse tropical forests, but reliable and ecologically relevant digital environmental data layersExpand
Erratum to: Newly discovered diversity in the tropical fern genus Metaxya based on morphology and molecular phylogenetic analyses
Based on the morphological variation among the Metaxya specimens, the authors accept six distinct species, three of which are described as new in this paper, which are considered true species despite the incomplete genetic differentiation. Expand
Taxonomy and evolutionary history of the neotropical fern genus Salpichlaena (Blechnaceae)
This work systematically documented 62 morphological traits in 283 herbarium specimens and sequenced 52 Salpichlaena specimens, suggesting that a group of specimens, placed into different clades in the plastid and nuclear trees and showing mixed morphological characters, represent a fourth species of hybrid origin.
