Figure 3From: Phylogeny of the nematode genus Pristionchus and implications for biodiversity, biogeography and the evolution of hermaphroditismBayesian tree of Pristionchus species based on ribosomal protein genes. The phylogenetic relationships were reconstructed from concatenated ribosomal protein CDS by Bayesian inference using the MrBayes 3.2.1 software [31]. The evolutionary model was set to GTR+I+G. The analysis was run for 150,000 generations, burn-in time was for 37,500 generations, sampling frequency was 1 in 100 generations. Koerneria sp. was included as the closest related genus to Pristionchus. The tree was rooted at midpoint. Numbers at nodes indicate posterior probabilities. Hermaphroditic and gonochoristic (male/female) species are marked. The geographic origins of the species are indicated.Back to article page
