Morphometric characterization of the Chordodes brasiliensis (Nematomorpha) larvae in The Tala river, Catamarca province [PDF]

open access: yes, 2023
The Gordiida (Nematomorpha) are obligate parasites of insects. Adults inhabit permanent and temporary aquatic environments. After mating, the female expels egg strings in the substrate or aquatic vegetation.

Revealing hidden sources of uncertainty in biodiversity trend assessments

open access: yesEcography, Volume 2025, Issue 5, May 2025.
Idiosyncratic decisions during the biodiversity trend assessment process may limit reproducibility, whilst ‘hidden' uncertainty due to collection bias, taxonomic incompleteness, and variable taxonomic resolution may limit the reliability of reported trends.

Stream Invertebrate Responses to Fine Sediment Depend on the Organic and Inorganic Components

open access: yesFreshwater Biology, Volume 70, Issue 3, March 2025.
ABSTRACT Excess fine sediment ( < 2 mm) is a pervasive stressor of aquatic systems at a global scale. To date, most research quantifying ecological response to deposited fine sediment has been conducted without distinguishing between the organic and inorganic components of fine sediment, leaving mechanistic understanding of how fine sediment affects ...

Evolution of the Cdk4/6–Cdkn2 system in invertebrates

open access: yesGenes to Cells, Volume 29, Issue 11, Page 1037-1051, November 2024.
Hypothesis on the evolution of the Cdkn2 locus. (a) Loss of Cdkn2 occurred multiple times. (b) Evolution of microsynteny at the Cdkn2 locus. Cdkn2e is a hypothetical transient gene. Abstract The cell cycle is driven by cyclin‐dependent kinases (Cdks). The decision whether the cell cycle proceeds is made during G1 phase, when Cdk4/6 functions.

A new Gordionus Müller, 1927 from Switzerland (Nematomorpha, Gordiidae)

open access: yes, 2010
To date only three species of freshwater Nematomorpha (Gordiida) are known from Switzerland. We report here the finding of two further species, the common species Gordionus violaceus (Baird, 1853) and a new species, G. bageli sp. n., in Switzerland.
