Genome duplication in the teleost fish Tetraodon nigroviridis reveals the early vertebrate proto-karyotype
TLDR
Genome analysis provides a greatly improved fish gene catalogue, including identifying key genes previously thought to be absent in fish, and reconstructs much of the evolutionary history of ancient and recent chromosome rearrangements leading to the modern human karyotype.

The genomic substrate for adaptive radiation in African cichlid fish
TLDR
It is concluded that a number of molecular mechanisms shaped East African cichlid genomes, and that amassing of standing variation during periods of relaxed purifying selection may have been important in facilitating subsequent evolutionary diversification.

Genetics of Sex Determination in Tilapiine Species
TLDR
Variation in sex determination mechanisms among closely related species of tilapiine fishes makes tilapias an excellent model system for studying the evolution of sex chromosomes in vertebrates.

Genome dynamics and chromosomal localization of the non-LTR retrotransposons Rex1 and Rex3 in Antarctic fish
TLDR
This report is the first description and analysis of retrotransposable elements in Antarctic fish genomes and suggests the presence of autosomal and gonosomal regions of preferential accumulation for different types of repeated elements in notothenioid genomes.

Conservation of the 5S-bearing chromosome pair and co-localization with major rDNA clusters in five species of Astyanax (Pisces, Characidae)
TLDR
Major and5S ribosomal genes have been localized in chromosomes from five fish species, genus Astyanax, using in situ hybridization (FISH) with 28S and 5S rDNA probes for elucidating evolutionary relationships among closely related taxa.

Chromosome studies on fish of the suborder notothenioidei collected in the weddell sea during epos 3 cruise
TLDR
La comparaison des nombres diploides et des formules chromosomiques avec ceux de certaines especes deja etudiees dans d'autres secteurs ne revele pas de variation intraspecifique significative significative and confirme ainsi the stabilite du critere caryotypique dans ces familles.
Characterization and repeat analysis of the compact genome of the freshwater pufferfish Tetraodon nigroviridis.
TLDR
The previously uncharacterized Tetraodon genome is described here together with a detailed analysis of its repeat content and organization, and the sequencing of 46 megabases of bacterial artificial chromosome end sequences, which represents a random DNA sample equivalent to 13% of the genome.

Viability of X-autosome translocations in mammals: an epigenomic hypothesis from a rodent case-study
TLDR
An epigenomic hypothesis is proposed which posits that constitutive heterochromatin is probably selected for in X-autosome translocations since it may protect the inactivated X from spreading to the autosomal part, and allow for the independent regulation of replication timing of the sex and autosomal segments.

Molecular and morphological phylogenies of the Antarctic teleostean family Nototheniidae, with emphasis on the Trematominae
TLDR
Four independent molecular data sets were sequenced in order to solve longstanding phylogenetic problems among Antarctic teleosts of the family Nototheniidae and show that the tendencies shown by some trematomines to secondarily colonize the water column are not gained through common ancestry.
