Supplemental Information

Genera used in this study and associated Genbank Accession Numbers

This .csv file contains a list of all Amazonian tree genera that are present in the phylogeny we constructed, as well as Genbank Accession numbers for the rbcL sequence and matK sequence where pertinent.

DOI: 10.7287/peerj.preprints.2043v1/supp-1

Fossil calibrations used to temporally date phylogeny

This .csv file lists the nodes for which ages were constrained as well as giving the minimum age, mean age and standard deviation for the log-normal prior distributions (with offset) used in BEAST analyses.

DOI: 10.7287/peerj.preprints.2043v1/supp-2

Taxonomic lineages present in paper with associated summary statistics

This .csv file lists each higher-than-genus-level lineage used in this study that has a Linnean taxonomic name. It then gives the age, number of constituent genera used in different analyses and reconstructed mean values for genus-level characteristics studied.

DNA Deposition

The following information was supplied regarding the deposition of DNA sequences:

Genbank. We used ~1000 sequences already available on Genbank (see Table S1 of article). We generated 61 new sequences. These are in the process of submission to Genbank, and accession numbers will be provided prior to publication.
