Figure 2 in Paraphyly of Marimermithida refines primary routes of transition to parasitism in roundworms

Figure 2. Bayesian tree of Nematoda based on concatenated rDNA data. Gene sampling maximizes the available coverage of SSU, 5.8S and LSU genes (accession IDs for each taxon correspond either to individual genes available, full cistrons or eDNA samples). The data covers the three major clades (Enoplia, Dorylaimia and Chromadoria), with extended sampling of marine Enoplia, and a selection of representative host-associations (in bold) for the clades. Parasitism-relevant life traits are mapped as pictograms, explained in the legend and addressed in the following discussion section. Traits apply either to a particular sampled species or more broadly to the subclade it represents (according to general knowledge of typical large subclades). Pictogram series denote the co-occurrence of traits either within subclade or individual life cycle. The habitat is colour-coded to generally typify subclades (e.g. as per Holterman et al., 2019), blue – marine; yellow – brackish/ limnic/terrestrial. Marine animal parasites/associates are listed in dark blue, brackish/limnic/terrestrial in red, while plant parasites/associates are shown in green. Nodes mismatched in BI and ML topologies are unlabelled. Otherwise, labels contain BI posterior probabilities (left) and ML bootstrap support (right). Values 0.95/95 dotted (●). BI posterior probabilities are calculated across GTR+Г parameter space in 3 M generations, ML bootstrap support estimated under GTR+F+G16 model in 100 replicates. NCBI accessions appended to taxon names, original sequences and assemblies marked with asterisk (*). Scale bar: substitutions per site.
