Recent Clessification |
Relationships among species, genera, and even families, within the Nematoda are becoming clearer as morphological, morphometric, and life history features are considered along with molecular-based phylogenies. However, there remain differences of opinion among experts regarding classifications above the family level. | |
| Rhabditida | ||
| Rhabditina | ||
| Rhabditomorpha | ||
| Mesorhabditoidea | ||
A superfamily peoposed by De Ley and Blaxter (2003) based on charcteristics (morphological and molecular) of families Pelodiridae and Mesorhabditidae, both proposed by Andrassy, 1976
Ref Andrassy, 2005
|
Families of the Mesorhabditoidea include: |
Common of nematodes in soil and other terrestrial habitats, especially with the presencee of decaying organic matter. Some are found in freshwater and martine habitats
Bacterivores, usually present where bacteria are abundant.
|
Important ecosystem services as participantas in the cycling of minerals and nutrients and in the mineralization of organic molecules which then become available for uptake by higher plants.
May be considered indicators of organically-rich and healthy soils. |
Bacterivores
Their abundaance can be promoted by orghanic amendments, maintaining rhizodeposition by continuous cultivation of plants and maintaining soil moisture.
