The complete mitochondrial genome of the Antarctic marbled rockcod, Notothenia rossii (Perciformes, Nototheniidae). [PDF]

open access: yesMitochondrial DNA B Resour, 2020
The complete mitochondrial genome of Notothenia rossii was obtained using PacBio Sequel long-read sequencing platform. The mitogenome of N. rossii was circular form and 18,274 bp long, which consists of 13 protein-coding genes, 24 tRNAs, 2 rRNAs, and non-coding control region.

Metabolic responses in Antarctic Nototheniidae brains subjected to thermal stress

open access: yesBrain Research, 2019
Antarctic Nototheniidae is an attractive group for studying metabolic and physiological responses at high temperatures. The present work investigated the metabolic responses of the carbohydrate metabolism and antioxidant system to thermal stress at 8 °C (for 2-144 h) in the brains of Notothenia rossii and Notothenia coriiceps. In N.

The Biodiversity of Peter I Island-The Most Remote Island in the World. [PDF]

open access: yesEcol Evol
Peter I Island is one of the most isolated and least visited islands on earth; lying within the Antarctic Polar Front but over 420 km from continental Antarctica. Here we assess the biodiversity of the island from both previous records and our own BioBlitz in January 2022.

Detecting the invisible through DNA metabarcoding: The role of gelatinous taxa in the diet of two demersal Antarctic key stone fish species (Notothenioidei)

open access: yesEnvironmental DNA, Volume 6, Issue 3, May–June 2024.
Gelatinous zooplankton (GZP) are considered climate change winners, and particularly in the Southern Ocean, a significant shift from a krill‐based to a salp‐based ecosystem has undergone. In this study, we want to validate the paradigm shift from GZP being considered as “survival food” to a “regular” prey item for two demersal fish species (Notothenia ...

Composition of cultivable enteric bacteria from the intestine of Antarctic fish (family Nototheniidae) [PDF]

open access: yesCzech Journal of Animal Science, 2016
Selenium (Se), copper (Cu), and zinc (Zn) play important antioxidant role during the transition period of dairy cattle. However, there is limited information about their blood fluctuations during the entire transition period, especially in heifers.

Insertion Hot Spots of DIRS1 Retrotransposon and Chromosomal Diversifications among the Antarctic Teleosts Nototheniidae. [PDF]

open access: yesInt J Mol Sci, 2019
By their faculty to transpose, transposable elements are known to play a key role in eukaryote genomes, impacting both their structuration and remodeling. Their integration in targeted sites may lead to recombination mechanisms involved in chromosomal rearrangements.

Toll-Like Receptor Evolution: Does Temperature Matter? [PDF]

open access: yesFront Immunol, 2022
Toll-like receptors (TLRs) recognize conserved pathogen-associated molecular patterns (PAMPs) and are an ancient and well-conserved group of pattern recognition receptors (PRRs).

Twenty-First-Century Environmental Change Decreases Habitat Overlap of Antarctic Toothfish (Dissostichus mawsoni) and Its Prey. [PDF]

open access: yesGlob Chang Biol
Antarctic toothfish are a commercially exploited upper‐level predator in the Southern Ocean, but knowledge on how Antarctic toothfish and its prey respond to environmental change remains incomplete. In this study, we employ the extended aerobic growth index to quantify changes in predator–prey viable habitat overlap in response to changes in ...

Composition of leucocytes in peripheral blood of Patagonian toothfish (Dissostichus eleginoides, Smitt, 1898) (Nototheniidae)

open access: yesPolar Research, 2017
The composition of leukocytes in the Patagonian toothfish (Dissostichus eleginoides Smitt, 1898), caught in the Scotia Sea at a depth of more than 1000 m, was studied. Cells with various morphofunctional characteristics and cell structure were found. Lymphocytes were predominant, followed by, in decreasing order, eosinophils, monocytes, blast forms and

First characterization of gastrointestinal culturable bacteria of Patagonian toothfish Dissostichus eleginoides (Nototheniidae) [PDF]

open access: yesRevista De Biologia Marina Y Oceanografia, 2019
The Patagonian toothfish Dissostichus eleginoides is one of the most important fisheries from the Southern Ocean. The biology of this species is relatively well studied and some nutritionals issues have also been reported; however there is no information about the composition of the bacterial community of the gastrointestinal tract, which is essential ...
