How to built a completely resolved species-level phylogeny using TCAT

A completely resolved species-level phylogeny is necessary for studies in macroevolution and macroecology. Sampling fraction and taxonomy are the two most commonly used methods to account for incomplete sampling, however, the pros and cons for both methods are unappreciated. Here I biefly demonstrate superior method --- TACT, using dated Vitales tree and its taxonomy to generate a completely resolved species-level Vitales tree.

Nat. Commun.: Recent accelerated diversification in rosids occurred outside the tropics

Conflicting relationships have been found between diversification rate and temperature across disparate clades of life. Here, we use a supermatrix comprising nearly 20,000 species of rosids—a clade of ~25% of all angiosperm species—to understand …


PhyloSynth is a collaborative group of scientists that aim to provide an updated framework and set of phylogenies for the plant tree of life.

Rosid Phylogeny and Diversification

**Rosids**, among the largest clades of angiosperms (90,000–120,000 species, ca. 25% of all angiosperms), exhibit tremendous overall diversity in morphology, chemistry, habit, reproductive strategy, and life history. However, our knowledge of this clade is remarkably limited along any sampling metric, hampering efforts to better understand its incredible species diversity.
