TY  - JOUR
AB - Metagenomics provides a powerful new tool set for investigating evolutionaryinteractions with the environment. However, an absence of model-basedstatistical methods means that researchers are often not able to make full useof this complex information. We present a Bayesian method for inferring thephylogenetic relationship among related organisms found within metagenomicsamples. Our approach exploits variation in the frequency of taxa among samplesto simultaneously infer each lineage haplotype, the phylogenetic treeconnecting them, and their frequency within each sample. Applications of thealgorithm to simulated data show that our method can recover a substantialfraction of the phylogenetic structure even in the presence of strong mixingamong samples. We provide examples of the method applied to data from greensulfur bacteria recovered from an Antarctic lake, plastids from mixedPlasmodium falciparum infections, and virulent Neisseria meningitidis samples.
