Persistent Gaps and Errors in Reference Databases Impede Ecologically Meaningful Taxonomy Assignments in 18S rRNA Studies: A Case Study of Terrestrial and Marine Nematodes

open access: yesEnvironmental DNA, Volume 7, Issue 2, March/April 2025.
Public molecular databases (i.e., SILVA, EUKARYOME, BOLD) for most microbial metazoan phyla (nematodes, tardigrades, kinorhynchs, etc.) are sparsely populated, negatively impacting our ability to assign ecologically meaningful taxonomy to these understudied groups.

Nematode community structure suggests perennial grain cropping cultivation as a nature‐based solution for resilient agriculture

open access: yesJournal of Sustainable Agriculture and Environment, Volume 3, Issue 3, September 2024.
Abstract Introduction Conventional agricultural land‐use may negatively impact biodiversity and the environment due to the increased disturbances to the soil ecosystem by tillage, for example. Cultivation of the perennial grain intermediate wheatgrass (Thinopyrum intermedium, IWG, Kernza®) is a nature‐based solution for sustainable agriculture ...

Awl Nematodes, Dolichodorus spp. Cobb, 1914 (Nematoda: Secernentea: Tylenchida: Tylenchina: Dolichodoridae: Dolichodorinae)

open access: yesEDIS, 2003
Awl nematodes were first described in 1914 from specimens collected at Silver Springs, Florida, and Douglas Lake, Michigan. Species of Dolichodorus are found worldwide, but two species, D. heterocephalus and D.

Marine sediment infauna‐based environmental assessment using metabarcoding identifies potential impact indicator species

open access: yesEnvironmental DNA, Volume 6, Issue 3, May–June 2024.
Intertidal infaunal community data are obtained via: (1) morphological identification of macroinvertebrates from sediment cores, (2) cytochrome c oxidase subunit I (COI) DNA metabarcoding of the same pooled macroinvertebrate specimens, and (3) 18S ribosomal RNA (18S) DNA metabarcoding of benthic meiofauna from small volume sediment surface scrapes.

Dolichodorus Profundus N. Sp. (Nematoda - Tylenchida)

open access: yesNematologica, 1960
The author describes and figures Dolichodorus profundus n. sp. This new species was found in the sandy soil of a coconut plantation near Akodessewa (Togo) at a depth of 1 to 1.2 m (0.2 to 0.4 m above the soil water table) and never in the more superficial layers of the soil, whereas other plant-parasitic nematodes found in this type of soil are more ...

Hoplolaimus Proporicus N.Sp. (Hoplolaiminae: Tylenchida)

open access: yesNematologica, 1957
Hoplolaimus proporicus n.sp. wird beschrieben und abgebildet. Der Nematode wurde im Zusammenleben mit den Wurzeln der Olpalme Elaeis guineensis gefunden. H. proporicus weicht von allen Hoplolaimus- Arten insofern ab, als er keine lateralen Felder aufweist und die Ringe rund um den Korper verlaufen mit Ausnahme an den beiden Enden des Nematoden, wo sie ...

Tylenchorhynchus tessellatus n.sp. (Nematoda : Tylenchida)

open access: yesJournal of Helminthology, 1952
During the examination of the eelworms assembled after washing pieces of turf by Thorne’s sieving technique (Goodey, T., 1949), which had been collected in a meadow at Winches Farm, St. Albans, several specimens of nematodes were found, both male and female, which were first identified as Tylenchorhynchus dubius (see Thorne, 1949).
