The exclusive common presence of fungivorous and plant parasitic nematodes supports a long-standing hypothesis that states that plant parasitic Nematodes arose from fungivory ancestors.
A phylogenetic tree of nematodes based on about 1200 full-length small subunit ribosomal DNA sequences.
The extensiveness of convergent evolution is one of the most striking phenomena observed in the phylogenetic tree presented here – it is hard to find a morphological, ecological or biological characteristic that has not arisen at least twice during nematode evolution.
Phylogeny of Cephalobina (Nematoda): molecular evidence for recurrent evolution of probolae and incongruence with traditional classifications.
Linking DNA sequences to morphology: cryptic diversity and population genetic structure in the marine nematode Thoracostoma trachygaster (Nematoda, Leptosomatidae)

Improved phylogenomic sampling of free-living nematodes enhances resolution of higher-level nematode phylogeny
Expanded transcriptome sequencing of free-living nematodes has contributed to better resolution among deep nematode lineages, though the dataset is still strongly biased toward parasites.

This list of terrestrial and freshwater nematodes from all regions of the Arctic, for which records of properly identified nematode species are available, includes 391 species belonging to 146 genera, 54 families and 10 orders of the phylum Nematoda.
Description of Phasmarhabditis californica n. sp. and first report of P. papillosa (Nematoda: Rhabditidae) from invasive slugs in the USA
Morphology, genetic distance, reproductive strategy and nucleotide autapomorphies support the new taxon, and phylogenetic analyses placed these two species in a monophyletic clade comprising Phasmarhabditis species and other gastropod-parasitic taxa.

The phylogeny-based approach using the evolutionary placement algorithm provided the largest number of positively assigned OTUs and was least affected by erroneous sequences and limitations of reference data, compared to alignment-based and tree-based approaches.
The role of habitat heterogeneity in structuring the community of intertidal free-living marine nematodes

The nematofauna of the structurally complex beach was more diverse than the one from a homogeneous beach nearby, supporting the hypothesis that structural heterogeneity promotes diversity by compartmentalization and highlighting the importance of microhabitats in the assessment of biodiversity.
