Data from: Estimating diversification rates on incompletely-sampled phylogenies: theoretical concerns and practical solutions

- 摘要：
- t are driven solely by unbalanced sampling across the tree in concert with low overall power to infer shifts. Stochastic polytomy resolution prov
Data from: Phylogenetic relationships and tempo of early diversification in Anolis lizards

- 摘要：
- phylogenetic divergences. We test the hypothesis that the major clades of anoles form a hard polytomy and present a general statistical framework

- 摘要：
- calculation. These approaches are applied to describe the distribution of potential signal, polytomy, or noise for two example datasets, one recent (CO1 and 28S

- ), and phylogenetic analyses recover these specimens as early-diverging neotheropods in a polytomy with other early neotheropods at the base of the clade
Data from: Species tree reconstruction of a poorly resolved clade of salamanders (Ambystomatidae) using multiple nuclear loci

- 摘要：
- unresolved, potentially highlighting a region of rapid species radiation or a hard polytomy, which limits our ability to comment on previous morphologically

Data from: Ecomorphological diversification among South American spiny rats (Rodentia, Echimyidae): a phylogenetic and chronological approach.
- 负责人：
- DOI：
- doi:10.5061/dryad.8509
- 摘要：
- polytomy of echimyids was partially resolved and unexpected intergeneric clades were recovered. Thus, the intimate nested position of Myocastor
Data from: Model choice, missing data and taxon sampling impact phylogenomic inference of deep Basidiomycota relationships
