Using oligochaeta assemblages as an indicator of environmental changes

Brazilian Journal of Biology
We designed a field survey (the entire river length; not dammed: First and Second plateaus; dammed: Third Plateau) to test the hypothesis that the cascade of reservoirs promoted a reduction in species richness and changed the composition of Oligochaeta ...

Oligochaeta (Annelida: Clitellata) associated to aquatic macrophytes in Brazil

Biotemas, 2016
Oligochaeta are still characterized as a poorly studied group among the aquatic macroinvertebrates and few studies about their ecology were conducted in Brazil.

They come in all sizes: integrative systematics and morphological radiation of Scherotheca (Lumbricidae, Crassiclitellata)

Cladistics, Volume 41, Issue 6, Page 581-599, December 2025.
Abstract Scherotheca is amongst the most diverse earthworm genera within Lumbricidae, exhibiting striking ecomorphological radiation—from small epigeic‐like forms to giant anecic species. Accurate systematics is critical for exploring such diversification.

Seasonal variations of diversity and abundance of the benthic Annelida in coastal sediments of the southern Caspian Sea (Mazandaran-Sari) [PDF]

بوم‌شناسی آبزیان, 2018
In order to investigate seasonal variation of diversity and abundance of Annelida, seasonal sediment sampling was performed on 10 stations with depths of 1, 5, 10 and 20 meters in the coastal area of Sari, Iran in 2015-2016.

Sorting of Glossiphonia complanata (Linnaeus, 1758) (Rhynchobdellida: Glossiphoniidae) from three aquatic plants in Tigris River within Baghdad city

Egyptian Journal of Petroleum, 2017
The present study shows that the reason for isolation of Glossiphonia complanata from these aquatic plants was firstly founding of aquatic oligochaeta, snails and chironomidae that settled on aquatic plants as food.

Is similar the distribution of Chironomidae (Diptera) and Oligochaeta (Annelida, Clitellata) in a river and a lateral fluvial area?

Acta Limnologica Brasiliensia, 2017
Numerous factors may affect the pattern of distribution of benthic fauna in a river mouth region and, among the macroinvertebrates, Chironomidae and Oligochaeta are the most abundant groups and most tolerant to environmental changes. Aim The aim of this
