Dorylaims
Dorylaimia is a subclass of nematodes. Description In general, members of subclass Dorylaimia exhibit a great diversity of terrestrial and freshwater species, most of which are large predators or omnivorous free-living species. Some are plant parasites, whereas others are animal parasites (Trichinellida and Mermithida). No members of the Dorylaimia are found in marine habitats. Dorylaimia bear an odontostyle, a protrusible, hollow, needlelike tooth for puncturing and emptying food items. Taxonomy Phylogenetic analysis of phylum Nematoda suggests three distinct basal clades, the dorylaims, enoplids, and chromadorids. These represent Clades I, II and C+S of Blaxter (1998). Of these, the first two appear to have sister clade status, allowing resolution into two classes, Enoplea and Chromadorea, and division of the former into two subclasses corresponding to Clades I and II respectively, the Enoplia and Dorylaimia. Nevertheless, the possibility remains that Dorylaimia will ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sister Clade
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Chromadorids
The Chromadorea are a class of the roundworm phylum, Nematoda. They contain a single subclass (Chromadoria) and several orders. With such a redundant arrangement, the Chromadoria are liable to be divided if the orders are found to form several clades, or abandoned if they are found to constitute a single radiation. Formerly, they were treated as a subclass in the paraphyletic "Adenophorea" assemblage, which has been mostly abandoned by modern authors. It is also suspected that the Chromadorea may not be monophyletic as delimited here; at least the Monhysterida seem to be a distinct and far more ancient lineage than the rest. Members of this class' bodies usually have annules, their amphids elaborate and spiral, and they all have three esophageal glands. They usually live in marine sediments, although they can live elsewhere. They have a more sophisticated pharynx than most roundworms. Members of this class can be identified by the presence of eight conserved signature indels (C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dorylaimida
Dorylaimida (dorylaims) is a diverse order of nematodes with both soil and freshwater species. Taxonomy History The order originated with the description of ''Dorylaimus stagnalis'' by Dujardin in 1845, and in 1876 De MAn proposed the family Dorylamidae, while Cobb added many other genera and subgenera. In 1927 Filipjev added a subfamily, Dorylaiminae, and by 1934 there were four subfamilies. That was when Thorne raised family Dorylaimidae to superfamily Dorylaimoidea. In 1936 Pearse raised it further to become a suborder of Enoplida, and in 1942 Pearse proposed the current order, Dorylaimida to encompass all of the dorylaim nematodes. Many reorganisations followed. For instance Clark (1961) did not accept Dorylaimida, whereas Goodey (1963) did. Other reclassifications include Jairajpuri (1964, 1969, 1976, 1980, 1983, 1992), Thorne (1964, 1967), Siddiqui (1968, 1983), Andrássy (1969, 1976), and Coomans and Loof (1970). The scheme shown here is that of Jairajpuri (1992), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
