Neutral and adaptive loci reveal fine‐scale population structure in Eleginops maclovinus from north Patagonia [PDF]
Ecology and Evolution, 2022 Patagonia is an understudied area, especially when it comes to population genomic studies with relevance to fishery management. However, the dynamic and heterogeneous landscape in this area can harbor an important but cryptic genetic population structure.

A chromosome-level reference genome of the Antarctic blackfin icefish Chaenocephalus aceratus [PDF]
Scientific Data, 2023 The blackfin Icefish (Chaenocephalus aceratus) belongs to the family Channichthyidae and the suborder Notothenioidei which lives in the Antarctic. We corrected the mis-scaffolds in the previous linkage map results by Hi-C analysis to obtain improved ...

The complete mitochondrial genome of the Antarctic marbled rockcod, Notothenia rossii (Perciformes, Nototheniidae) [PDF]
Mitochondrial DNA. Part B. Resources, 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-

Accelerated evolution at chaperone promoters among Antarctic notothenioid fishes [PDF]
BMC Evolutionary Biology, 2019 Background Antarctic fishes of the Notothenioidei suborder constitutively upregulate multiple inducible chaperones, a highly derived adaptation that preserves proteostasis in extreme cold, and represent a system for studying the evolution of gene ...

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

A proteome-scale analysis of vertebrate protein amino acid occurrence: Thermoadaptation shows a correlation with protein solvation but less so with dynamics. [PDF]
Proteins, 2023 Abstract Despite differences in behaviors and living conditions, vertebrate organisms share the great majority of proteins, often with subtle differences in amino acid sequence. Here, we present a simple way to analyze the difference in amino acid occurrence by comparing highly homologous proteins on a subproteome level between several vertebrate model
