Improving the resolution and informativity of the majority-rule consensus tree using fine-grained dissimilarity measures
Phylogenetic analyses often require the summarization of multiple trees, e.g., in Bayesian analyses to obtain the centroid of the posterior distribution of trees, or to determine the consensus of a set of bootstrap trees. The majority-ru...

A Taxonomist’s Guide to the Genealogical Divergence Index
Speciation proceeds independently across lineages, generating varying levels of genetic divergence that are difficult to translate into discrete species boundaries. Widely used empirical heuristics such as genetic distance thresholds, DN...

Exploring the Abiotic and Biotic drivers of uneven Species Richness in Salamanders and Newts
Species richness varies widely among taxonomic groups, and understanding the drivers of these disparities remains a key challenge. Using the most recent time-calibrated phylogeny of Caudata (763 species), we investigated how abiotic and ...

Properties of Biodiversity Indices that Incorporate Future Extinction Risk
The loss of biodiversity due to the likely widespread extinction of species in the near future is a focus of current concern in conservation biology. One approach to measure the impact of this extinction is based on the predicted loss of...

"Early-Diverging" Lineages Provide Little Information about Ancestors
Large phylogenetic trees are often unbalanced near the root, with a species-depauperate lineage sister to a far more species-rich clade. The species-poor branches, sometimes referred to as “early diverging,” are often viewed as key sourc...

Challenges for Reproducibility in Species Delimitation
Species richness is a foundational metric for comparing biodiversity among clades and regions in ecology, evolution, and conservation. As the biodiversity crisis accelerates, taxonomists face increasing pressure to delimit and name speci...

Which Characters Support Which Clades? Exploring the Distribution of Phylogenetic Signal Using Mutual Information
Understanding which individual characters provide evidence for specific edges in a phylogeny is crucial when evaluating datasets of discrete phylogenetic characters, yet most support measures summarize evidence across all sites. I introd...

TreeFlow: Probabilistic Modeling and Automatic Differentiation for Phylogenetics
Probabilistic modeling frameworks are powerful tools for statistical modeling and inference. They are not immediately generalizable to phylogenetic problems due to the particular computational properties of the phylogenetic tree object. ...

Macroevolutionary Rates of Species Interactions: Approximate Bayesian Inference from Cophylogenies
Understanding the macroevolutionary dynamics of species interactions such as parasitisms, commensalisms, and mutualisms is an important goal in evolutionary ecology. To this end, statistical inference from time-calibrated cophylogenies h...

Benchmarking Assembly-Free K-mer Methods for Species Identification in Complex Plant Groups: A Case Study in Populus
Species identification in taxonomically complex plant groups is frequently limited by the inadequacy of organellar markers, whose phylogenetic signal is disrupted by cytonuclear discordance and chloroplast capture. Using the taxonomicall...
