MODELTEST: testing the model of DNA substitution.

Abstract SUMMARY: The program MODELTEST uses log likelihood scores to establish the model of DNA evolution that best fits the data. AVAILABILITY: The MODELTEST package, includin...

jModelTest: Phylogenetic Model Averaging

jModelTest is a new program for the statistical selection of models of nucleotide substitution based on "Phyml" (Guindon and Gascuel 2003. A simple, fast, and accurate algorithm...

Model Selection and Model Averaging in Phylogenetics: Advantages of Akaike Information Criterion and Bayesian Approaches Over Likelihood Ratio Tests

Model selection is a topic of special relevance in molecular phylogenetics that affects many, if not all, stages of phylogenetic inference. Here we discuss some fundamental conc...

Selecting the Best-Fit Model of Nucleotide Substitution

Despite the relevant role of models of nucleotide substitution in phylogenetics, choosing among different models remains a problem. Several statistical methods for selecting the...

The Effect of Branch Length Variation on the Selection of Models of Molecular Evolution

TCS: a computer program to estimate gene genealogies

Phylogenies are extremely useful tools, not only for establishing genealogical relationships among a group of organisms or their parts (e.g. genes), but also for a variety of re...

Mitochondrial DNA phylogeography and population history of the grey wolf<i>Canis lupus</i>

Abstract The grey wolf ( Canis lupus ) and coyote ( C. latrans ) are highly mobile carnivores that disperse over great distances in search of territories and mates. Previous gen...
