Geography and ecology shape the phylogenetic composition of Amazonian tree communities

Aim: Amazonia hosts more tree species, from numerous evolutionary lineages both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonised multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types.
Location: Amazonia.
Taxon: Angiosperms (Magnoliids; Monocots; Eudicots).
Methods: Data for the abundance of 5,082 tree species in 1,989 plots were combined with a mega-phylogeny. We applied evolutionary ordination to assess how phylogenetic composition varies across Amazonia. We used variation partitioning and Moran’s eigenvector maps (MEM) to test and quantify the separate and joint contributions of spatial and environmental variables to explain the phylogenetic composition of plots. We tested the indicator value of lineages for geographic regions and edaphic forest types and mapped assoc..., Geography and ecology shape the phylogenetic composition of Amazonian tree communities
Data files derived from the abundance of 5,082 tree species in 1,989 plots across Amazonia and used to support the findings described in Luize et al., 2024 Geography and ecology shape the phylogenetic composition of Amazonian tree communities, Journal of Biogeography.
This dataset includes three files:
1) Data contains the location of 1,989 tree inventory plots in Amazonia, associated evoPCA scores, and environmental data for each plot. To produce the evoPCA scores, we combined the abundance of 5,082 tree species with the phylogenetic relationships between species present in each plot. The environmental data for each plot was extracted from referenced data sources based on the locations of the plots. For soil attributes, we obtained point-data from soil profiles available in Soterlac (Dijkshoorn et al., 2005), ISRIC wise (Batjes, 2016), RAINFOR sites (Quesada et al., 2010), and Poels (1987), Zuquim et..., , # Geography and ecology shape the phylogenetic composition of Amazonian tree communities
