Complete mitochondrial genome of Trematomus newnesi (Perciformes, Nototheniidae). [PDF]

Mitochondrial DNA B Resour, 2023
The complete mitochondrial genome of Trematomus newnesi was sequenced using an Illumina platform. The 18,602 bp mitogenome contains 13 protein-coding genes, two rRNAs, and 23 tRNAs (tRNAMet is duplicated). The eight stop codons are TAA, TAG, CTT, GTA, AAT, ACT, AGG, and TTA. Two start codons ATG and GTG are present.

The complete mitochondrial genome of Trematomus loennbergii (Perciformes, Nototheniidae). [PDF]

Mitochondrial DNA B Resour, 2021
The complete mitochondrial genome of Trematomus loennbergii was studied using NGS technology with PacBio platform. The mitochondrial genome size was 19,374bp and it had 13 protein-coding genes, 22 tRNAs and 2 rRNAs. There were 4 types of stop codons which were TAA, TAG, AGG and T(AA) but start codon type was only one (ATG).

Anthropogenic microparticles in the emerald rockcod Trematomus bernacchii (Nototheniidae) from the Antarctic. [PDF]

Sci Rep, 2022
AbstractAnthropogenic microparticles (AMs) were found for the first time in specimens of Trematomus bernacchii collected in 1998 in the Ross Sea (Antarctica) and stored in the Antarctic Environmental Specimen Bank. Most of the identified AMs were fibers of natural and synthetic origin. The natural AMs were cellulosic, the synthetic ones were polyester,

The complete mitochondrial genome of Gobionotothen gibberifrons (Perciformes, Nototheniidae). [PDF]

Mitochondrial DNA B Resour
The humped rockcod, Gobionotothen gibberifrons, is an Antarctic fish of the genus Gobionotothen in the family Nototheniidae and order Perciformes. To date, little biological information has been recorded about the genus Gobionotothen. Here, we report the first complete mitogenome of the genus Gobionotothen. The mitochondrial genome of G.

Are Sponges Good Natural Sentinels for Monitoring Fish Diversity in Antarctic Coastal Waters? [PDF]

Ecol Evol
This study demonstrates that eDNA metabarcoding using both water and sponge samples is an effective tool for monitoring fish biodiversity along the Western Antarctic Peninsula. The results revealed 14 endemic Antarctic fish species and one marine mammal, with water samples often offering a more comprehensive view than sponges.

Sex Differentiation and Long-Distance Gene Flow in the Elusive Antarctic Fish <i>Aethotaxis mitopteryx</i>. [PDF]

Ecol Evol
This genetic study of a rare Antarctic fish, the longfin icedevil (Aethotaxis mitopteryx) investigates population connectivity across the Weddel Sea, revealing little to no differentiation even over vast geographic distances. Unexpectedly, the strongest genetic differentiation is instead observed between male and female fishes, which suggests a ...

Recovering Historical eDNA From Museum-Preserved Filter Feeders via Non-Destructive Metabarcoding. [PDF]

Mol Ecol Resour
ABSTRACT Recent technical advances have significantly enhanced the value of museum specimens for molecular research, with metagenomic and metabarcoding approaches expanding further the utility of museum collections. However, given the finite number of specimens, there is a critical need to move past destructive DNA extraction approaches and to explore ...

The complete mitochondrial genome of Trematomus hansoni Boulenger, 1902 (Perciformes, Nototheniidae). [PDF]

Mitochondrial DNA B Resour
The striped notothen Trematomus hansoni is an Antarctic fish species belonging to the family Nototheniidae (cod icefishes) that is distributed throughout the Southern Ocean. In this study, the complete mitochondrial genome of T. hansoni was sequenced using an Illumina MiSeq platform.

Single Copies of the 5S rRNA Inserted into 45S rDNA Intergenic Spacers in the Genomes of Nototheniidae (Perciformes, Actinopterygii). [PDF]

Int J Mol Sci, 2023
In the vast majority of Animalia genomes, the 5S rRNA gene repeats are located on chromosomes outside of the 45S rDNA arrays of the nucleolar organiser (NOR). We analysed the genomic databases available and found that a 5S rDNA sequence is inserted into the intergenic spacer (IGS) between the 45S rDNA repeats in ten species of the family Nototheniidae (

Embryonic and larval development of Dissostichus eleginoides (Pisces: Nototheniidae) [PDF]

Revista De Biologia Marina Y Oceanografia, 2016
espanolEl desarrollo embrionario y larval de Dissostichus eleginoides es descrito por primera vez utilizando ejemplares cultivados en laboratorio (4 a 8°C). Periodicamente fueron fijados huevos y larvas para describir el desarrollo. Los huevos midieron de 3,1 a 3,5 mm de diametro, esfericos, de corion transparente y superficie levemente rugosa, con 28 ...
