Molecular zoogeography of Antarctic euphausiids and notothenioids: from species phylogenies to intraspecific patterns of genetic variation [PDF]
, 2000 Published and unpublished data are used to investigate possible mechanisms of species diversification in two key soups of Antarctic organisms. the Notothenioidei and the Euphausiidae.

Identification of a novel helitron transposon in the genome of Antarctic fish [PDF]
, 2011 A novel helitron from the genome of the icefish species Chionodraco hamatus, belonging to the Channichthyidae, the most derived Notothenioids family, was isolated, characterized and designated as HeliNoto (8.9 kb).

Marine and Fishery SciencesMicrofibers (MFs) are an anthropogenic pollutant with a major impact on the marine environment. Due to their size, they can be ingested directly (from the environment) or indirectly (with their prey) by organisms. The aim of this study was to analyze and

Zonation of demersal fishes off Anvers Island, Western Antarctic Peninsula [PDF]
, 2016 The Antarctic fish fauna from outer continental shelf/upper slope depths is under-sampled compared to that of the inner shelf, and there are limited quantitative data available on absolute abundance and taxonomic change with depth.

Cold Fusion: Massive Karyotype Evolution in the Antarctic Bullhead Notothen Notothenia coriiceps
G3: Genes, Genomes, Genetics, 2017 Half of all vertebrate species share a series of chromosome fusions that preceded the teleost genome duplication (TGD), but we do not understand the causative evolutionary mechanisms.

Molecular basis of mitochondrial form and function in the hearts of antarctic notothenioids that vary in the expression of hemoglobin and myoglobin [PDF]
, 2008 Thesis (M.S.) University of Alaska Fairbanks, 2008Antarctic icefish (suborder Notothenioidei, family Channichthyidae) do not express hemoglobin (Hb), and 6 of the 16 members of this family do not express myoglobin (Mb) in their cardiac muscle.

Figure 3 in The complete mitochondrial genome of the mackerel icefish, Champsocephalus gunnari (Actinopterygii: Channichthyidae), with reference to the evolution of mitochondrial genomes in Antarctic notothenioids [PDF]
, 2012 Figure 3. Map of the mackerel icefish mitochondrial (mt) genome as a circular diagram. The map represents the mt genome of a type-1 individual in which ND6 and tRNAGlu were transposed to a position between tRNAThr and tRNAPro flanked by intergenic ...

Orphan genes are not a distinct biological entity
BioEssays, Volume 47, Issue 1, January 2025.Orphan genes represent genes with no homologs in other species and are widely assumed to represent genuine species‐specific loci. We show that molecular evolution and sequence homology analyses reject this assumption and that orphan genes constitute a patchwork of genes of different evolutionary ages that originate throughout various mechanisms ...

Klumpy: A tool to evaluate the integrity of long‐read genome assemblies and illusive sequence motifs
Molecular Ecology Resources, Volume 25, Issue 1, January 2025.Abstract The improvement and decreasing costs of third‐generation sequencing technologies has widened the scope of biological questions researchers can address with de novo genome assemblies. With the increasing number of reference genomes, validating their integrity with minimal overhead is vital for establishing confident results in their ...
