Fig. 4From: Improved phylogenomic sampling of free-living nematodes enhances resolution of higher-level nematode phylogenySimplified nematode phylogeny based on Fig. 2 indicating marine versus freshwater/terrestrial distribution for each order, considering the distribution of the majority of species. Notes: * includes equal number of marine, freshwater and terrestrial taxa, with molecular phylogenies suggesting terrestrial clades to be earlier (deeper); ** based on distribution of hosts, marine taxa may be of secondary origin; *** based on distribution of hosts; **** based on distribution of hosts and free-living stagesBack to article page
