A multiPhylo list of 50 phylogenetic trees sampled from the 100-tree
BirdTree bird collection retrieved through megatrees. The collection's
first 50 trees use the Ericson backbone and its next 50 use the Hackett
backbone. The fixed sample generated with seed 42 contains 28 Ericson and
22 Hackett trees, each pruned to the 300 species in avonet300.
Topologies and branch lengths vary across this posterior sample. The MIT
software licence for megatrees does not establish rights for the
underlying BirdTree data; see the installed NOTICE.
Source
Li (2026), megatrees 1.0.0; trees pruned from
megatrees::get_tree_bird_n100(). The source collection and its
Ericson and Hackett backbones are described by Ericson et al. (2006),
Hackett et al. (2008), and Jetz et al. (2012).
Details
Use with multi_impute_trees for experimental sensitivity of
point imputations to posterior-tree choice. Tree uncertainty is not
supported by the analysis-aware MI backend, and these stochastic datasets
are not validated for downstream inference.
