A classification of the entire Phylum Nematoda is presented, based on current molecular,
developmental and morphological evidence. The classification reflects the evolutionary …

Herein we review theoretical and methodological considerations important for finding and
delimiting cryptic species of parasites (species that are difficult to recognize using traditional …

As a result of the scarcity of informative morphological and anatomical characters, nematode
systematics have always been volatile. Differences in the appreciation of these characters …

Apical extracellular matrices (aECMs) coat the exposed surfaces of animal bodies to shape
tissues, influence social interactions, and protect against pathogens and other …

21. Originally placed in order Alaimida on the basis of general similarities in the thin body
shape and the rudimentary buccal cavity, here regarded as a suborder of Ironida on the …

Background A surprising amount of developmental variation has been observed for
otherwise highly conserved features, a phenomenon known as developmental system drift …

Molecular phylogenetic analyses of 113 taxa representing Ascaridida, Rhigonematida,
Spirurida and Oxyurida were used to infer a more comprehensive phylogenetic hypothesis …

Tylenchina are a morphologically and functionally diverse group of nematode species that
range from free-living bacteriovores, over transitory grazing root-hair feeders to highly …

Abstract Background The orders Ascaridida, Oxyurida, and Spirurida represent major
components of zooparasitic nematode diversity, including many species of veterinary and …

Knowledge of rRNA structure is increasingly important to assist phylogenetic analysis
through reconstructing optimal alignment, utilizing molecule features as an additional source …
