| Some information has been gathered on the expression of transcription factors associated with segmentation and regeneration in oligochaete annelids. |
|
| Some oligochaete species can secrete a tough mucous covering to protect themselves against either summer heat or winter cold. |
|
| A substantial increase in the abundance of pollution-tolerant oligochaete worms generally occurs in this zone at the expense of sensitive taxa. |
|
| Fine mud and muddy sands with a freshwater influence are characterized by oligochaete worms. |
|
| Commensalism occurs in some aquatic oligochaete species. |
|
| The amount of glycogen, a complex carbohydrate that serves as an energy source in animals, in the oligochaete Eisenia decreases markedly near the point of injury, returning to normal only after regeneration is complete. |
|
| To assess species diversity and abundance of aquatic oligochaete communities in order to determine the trophic status and relative health of benthic communities in the Great Lakes. |
|
| It would be important to evaluate the amplification rate of these four OTUs when oligochaete communities change and when other taxocenoses than oligochaetes are present. |
