A micro‐CT approach to the anatomy of Pectinariidae Quatrefages, 1866 (Annelida)
Abstract The Micro‐computed X‐ray tomography (micro‐CT) technique is used to examine the external and internal anatomy of four species of Pectinariidae (Annelida: Terebellida): Amphictene auricoma, Cistenides granulata, Cistenides hyperborea and Lagis sp., from material collected off Iceland and NW Spain.

Mitochondrial genome of Pseudopotamilla reniformis (Annelida: Sabellidae)
Here, we report the complete mitochondrial genome of sabellid Pseudopotamilla reniformis (Bruguière, 1789) (16,408 bp) and comprised of two ribosomal RNAs, the ubiquitous set of 13 protein-coding sequences, and 22 tRNAs. The order of protein-coding genes

Biodiversity in mountain soils above the treeline
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

Mitochondrial genome of Sabella spallanzanii (Gmelin, 1791) (Sabellida: Sabellidae)
We report the mitochondrial genome of Sabella spallanzanii, an invasive Mediterranean sabellid introduced to Australia and New Zealand. The mitogenome is 15,581 bp long and consists of 38 genes, including 13 protein coding genes, two rRNA genes, and 23 ...

Influence of Chironomus riparius (Diptera, Chironomidae) and Tubifex tubifex (Annelida, Oligochaeta) on oxygen uptake by sediments. Consequences of uranium contamination [PDF]
The diffusive oxygen uptake (DOU) of sediments inhabited by Chironomus riparius and Tubifex tubifex was investigated using a planar oxygen optode device, and complemented by measurements of bioturbation activity.

The evolution of reproduction in Ediacaran–Cambrian metazoans
ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

Species delimitation in Amblyosyllis (Annelida, Syllidae)
Amblyosyllis is a worldwide distributed group of annelids mainly found in coastal environments. It is well known among the polychaete specialists mostly because of its notable beauty, showing bright colourful patterns and outstanding long and coiled appendices.

d‐amino acids: new functional insights
This review explores recent advances in understanding d‐amino acids (d‐AAs) and their pivotal roles across organisms, from plants to humans. d‐AAs have been implicated in key physiological processes, including cancer, inflammation, immune regulation, kidney disease, diabetes, and nervous system function.
