Comparative Multi-Marker Environmental DNA Metabarcoding of Marine Metazoan Communities: Water vs. Sediment. [PDF]

open access: yesMol Ecol Resour
ABSTRACT This study investigates the metazoan biodiversity in the Southern Adriatic Sea using environmental DNA (eDNA) metabarcoding. Sediment and adjacent water samples were collected from three sites (one pristine, two impacted by human activities) at three distances from the coast across two seasons.

Designation of a neotype for the dwarf sea hare Aplysia concava G. B. Sowerby I, 1833, and a review of the status of Aplysia norfolkensis G. B. Sowerby II, 1869 (Mollusca: Heterobranchia)

open access: yesRecords of the Australian Museum, 2021
A recent revision of the globally distributed dwarf sea hare Aplysia parvula sensu lato split that species into 10 separate taxa. As Australian specimens were not included in this revision, further study using material from the south west Pacific was ...

Evolution of the Cdk4/6-Cdkn2 system in invertebrates. [PDF]

open access: yesGenes Cells
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.

Mannitol oxidase and polyol dehydrogenases in the digestive gland of gastropods: Correlations with phylogeny and diet. [PDF]

open access: yesPLoS ONE, 2018
Mannitol oxidase and polyol dehydrogenases are enzymes that convert polyalcohols into sugars. Mannitol oxidase was previously investigated in terrestrial snails and slugs, being also present in a few aquatic gastropods.

Nemesignis, a Replacement Name for Nemesis Furfaro & Mariottini, 2021 (Mollusca, Gastropoda, Myrrhinidae), Preoccupied by Nemesis Risso, 1826 (Crustacea, Copepoda)

open access: yesLife, 2021
The genus Nemesis Furfaro & Mariottini, 2021, was recently introduced for an independent lineage of aeolid nudibranchs, and Dondice banyulensis Portmann & Sandmeier, 1960, established as its type species. Anyway, the presence of a senior homonym, Nemesis
