An Integrated Model of Phenotypic Trait Changes and Site-Specific Sequence Evolution.

abstract：:Rapidly evolving pathogens, such as viruses and bacteria, accumulate genetic change at a similar timescale over which their epidemiological processes occur, such that, it is possible to make inferences about their infectious spread using phylogenetic time-trees. For this purpose it is necessary to choose a phylodynami...
