Phylum-wide analysis of SSU rDNA reveals deep phylogenetic relationships among nematodes and accelerated evolution toward crown Clades.
TLDR
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.
TLDR
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.
Linking DNA sequences to morphology: cryptic diversity and population genetic structure in the marine nematode Thoracostoma trachygaster (Nematoda, Leptosomatidae)
TLDR
Linking DNA sequences to morphology: cryptic diversity and population genetic structure in the marine nematode Thoracostoma trachygaster (Nematoda, Leptosomatidae).
Phylogeny of Cephalobina (Nematoda): molecular evidence for recurrent evolution of probolae and incongruence with traditional classifications.
TLDR
For Cephalobidae, molecular trees do not support traditional genera as natural groups, but it remains untested if deconstructing probolae morphotypes or other structural features into finer component characters may reveal homologies that help delimit evolutionary lineages.

TLDR
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
TLDR
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 role of habitat heterogeneity in structuring the community of intertidal free-living marine nematodes
TLDR
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.
Taxonomy assignment approach determines the efficiency of identification of OTUs in marine nematodes
TLDR
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.
NGS-based biodiversity and community structure analysis of meiofaunal eukaryotes in shell sand from Hållö island, Smögen, and soft mud from Gullmarn Fjord, Sweden
TLDR
NGS-based biodiversity and community structure analysis of meiofaunal eukaryotes in shell sand from Hallo island, Smogen, and soft mud from Gullmarn Fjord, Sweden shows positive associations with infectious disease and fungal establishment.
Description of Deleyia gen. n. with a discussion of its phylogenetic relationships to the genera Daubaylia Chitwood & Chitwood, 1934 and Myolaimus Cobb, 1920 (Nematoda: Rhabditida)
The new genus Deleyia gen. n., including two new species, D. poinari gen. n., sp. n. and D. aspiculata gen. n., sp. n., is described from terrestrial material (rotting wood and moss) in Ukraine. The
