Outbreaks of multidrug-resistant bacteria present a frequent threat to vulnerable patient
populations in hospitals around the world. Intensive care unit (ICU) patients are particularly …

Abstract Information criteria (ICs) based on penalized likelihood, such as Akaike's
information criterion (AIC), the Bayesian information criterion (BIC) and sample-size …

The degree of evolutionary conservation of an amino acid in a protein or a nucleic acid in
DNA/RNA reflects a balance between its natural tendency to mutate and the overall need to …

Determining the most suitable model for phylogeny reconstruction constitutes a fundamental
step in numerous evolutionary studies. Over the years, various criteria for model selection …

Founder-event speciation, where a rare jump dispersal event founds a new genetically
isolated lineage, has long been considered crucial by many historical biogeographers, but …

Historical biogeography has a diversity of methods for inferring ancestral geographic ranges
on phylogenies, but many of the methods have conflicting assumptions, and there is no …

In phylogenetic analyses of molecular sequence data, partitioning involves estimating
independent models of molecular evolution for different sets of sites in a sequence …

Ockham's razor, the principle of parsimony, states that simpler theories are better than
theories that are more complex. It has a history dating back to Aristotle and it plays an …

Background Partitioning involves estimating independent models of molecular evolution for
different subsets of sites in a sequence alignment, and has been shown to improve …

The field of phylogenetics is on the cusp of a major revolution, enabled by new methods of
data collection that leverage both genomic resources and recent advances in DNA …
