Toxicogenomics of the Freshwater Oligochaete, Tubifex tubifex (Annelida, Clitellata), in Acute Water-Only Exposure to Arsenic

International Journal of Molecular Sciences
A toxicogenomic approach was used for toxicity evaluation of arsenic in the aquatic environment, and differential gene expression was investigated from 24 h and 96 h water-only acute toxicity tests with the aquatic oligochaete, Tubifex tubifex (Annelida,

Synthesis of Population Trends Reveals Seascape‐Wide Reorganisation of Biodiversity From Microalgae to Birds

Global Change Biology, Volume 31, Issue 6, June 2025.
We present a systematic and quantitative analysis of population trends to capture the seascape‐wide reorganisation of biodiversity from microalgae to birds. First, we categorised population trends and found over one third of populations in the Wadden Sea to change, that is, increase or decrease.

Metagenomic Insights Into the Dietary Diversity of the Adaptive Radiation of Cichlid Fishes in Lake Tanganyika

Molecular Ecology, Volume 34, Issue 9, May 2025.
ABSTRACT Diet specialisation is a main driver of diversification in many adaptive radiations. Therefore, identifying diet items is essential to characterise trophic specialisations and to understand the dynamics of dietary adaptations. In this study, we explored the trophic niches of 56 species from the adaptive radiation of cichlid fishes in Lake ...

Winterfell survivor: The European phylogeography of a riparian earthworm (Annelida, Clitellata)

Zoologica Scripta, Volume 54, Issue 3, Page 394-405, May 2025.
Abstract Although some earthworms can survive in permafrost and tolerate cold conditions, it is generally believed that most earthworms were eradicated from northern latitudes during the Last Glacial Maximum. The main goal of this study is to test this hypothesis using a cosmopolitan earthworm as model, Eiseniella tetraedra. We collected 1640 specimens

First time observations of the earthworm species Octolasion cyaneum (Savigny) and Aporrectodea rosea (Savigny) (Oligochaeta: Lumbricidae) in northern Norway

Fauna Norvegica, 1994
The earthworm species Octolasion cyaneum and Aporrectodea rosea were observed in northern Norway for the first time in 1989 and 1992 respectively. The observations were made at Tromsø, on the southern part of the island Tromsøya (69°39'N, 18° 55'E).

Ecotoxicological Effects of Commercial Microplastics on Earthworm Eisenia fetida (Savigny, 1826) (Clitellata; Lumbricidae)

Agriculture
As soil invertebrates with a unique digestive system, earthworms are regularly used as bioindicators and test organisms. Due to their burrowing activity and casting, earthworms are involved in the structuring of the soil.

First records of Potamothrix bedoti (Piguet) and Haber speciosus (Hrabé) (Oligochaeta: Tubificidae) from Norway

Fauna Norvegica, 1995
The first record of Potamothrix bedoti (Piguet, 1913) in Norway is from the eutrophic lake Årungen 34 m a.s.l. (59°45'N, 10°41'E) in the county of Akershus, where 31 mature specimens were collected in the littoral zone from 1.0 to 3.0 m depth in silt ...

The groundwater oligochaetes (Annelida, Clitellata) of Slovenia

Subterranean Biology, 2011
Historical data on the biodiversity of oligochaetes inhabiting ground waters of Slovenia depicted a fauna of 25 species, 19 of which are stygobiotic. Over about the last 35 years, faunistic surveys carried out in Slovenian ground waters has enabled us to

On a collection of enchytraeids (Oligochaeta) from first order streams in São Paulo State, Brazil [PDF]

Opuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, 2017
A collection of 21 ethanol-preserved specimens of enchytraeids collected in first order streams in São Paulo State, Brazil, was whole-mounted on slides and investigated under light microscope.
