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.

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.

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.

- 19 August 2014
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.
Taxonomy assignment approach determines the efficiency of identification of OTUs in marine nematodes

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.
