Distribution of a supernumerary chromosome system and aspects of karyotypic evolution in the genus Prochilodus (Pisces, Prochilodontidae)
E. Pauls,L. A. C. Bertollo +1 more
TL;DR: The high karyotypic similarity detected demonstrated that, at least in these eight species, evolution occurred without marked changes in chromosome macrostructure.

A standard protocol for obtaining fish chromosomes under post-mortem conditions.
TL;DR: The results obtained from 24 neotropical freshwater and marine fish species demonstrate that chromosomes can be obtained under post-mortem conditions, and the samples analyzed provided reliable cytogenetical data in nearly all cases.

Cytogenetic Analysis of Coral Reef Fishes from Brazil (Families Pomacanthidae and Chaetodontidae)
TL;DR: Three perciform species associated to coral reefs were, for the first time, investigated under a cytogenetic focus: Holacanthus ciliaris and H. tricolor from family Pomacanthidae and Chaetodon striatus from family Chaetodontidae.
25
Close karyotypical relationship between two species of marine angelfishes from South Atlantic: Pomacanthus arcuatus and P. paru (Perciformes, Pomacanthidae)
TL;DR: The high level of resemblance between karyotypes from both species indicates their close phylogenetic relationship and diverges, although slightly, from the cytogenetical pattern so far described for Pomacanthidae representatives.

Evidence for a System of Supernumerary Chromosomes in Prochilodus Scrofa Steindachner, 1881 (Pisces, Prochilodontidae)
E. Pauls,L. A. C. Bertollo +1 more
TL;DR: This is the first report of chromosomes of this type in the Osteichthyes (Pisces) studied, and the unstable behavior of these chromosomes during mitosis and meiosis as well as their heterochromatic nature, as detected by C-banding, are characteristics that emphasize their supernumerary nature.
