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 …

AJB: Estimating rates and patterns of diversification with incomplete sampling: a case study in the rosids

Recent advances in generating large‐scale phylogenies enable broad‐scale estimation of species diversification. These now common approaches typically are characterized by (1) incomplete species coverage without explicit sampling methodologies and/or …

MPE: Accelerated diversification correlated with functional traits shapes extant diversity of the early divergent angiosperm family Annonaceae

A major goal of phylogenetic systematics is to understand both the patterns of diversification and the processes by which these patterns are formed. Few studies have focused on the ancient, species-rich Magnoliales clade and its diversification …

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.
