Abstract The notothenioids are an Antarctic suborder of perciform fishes to which increasing interest is being devoted. To investigate their origin, one must address two questions. First, are Bovichtidae (Bovichtus, Cottoperca, Pseudaphritis), the sister-group of the rest of the suborder, monophyletic ? Secondly, what is the sister-group of the Notothenioidei ? These questions were addressed by determining the complete nucleotide sequence of the D2 and D8 domains of 28S rDNA (759 sites, among… 
Molecular phylogenetics and the evolution of antarctic notothenioid fishes.
Molecular and morphological phylogenies of the Antarctic teleostean family Nototheniidae, with emphasis on the Trematominae
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.
Karyotypes of basal lineages in notothenioid fishes: the genus Bovichtus
The chromosomes of fishes from the family Bovichtidae, the basal lineage of the largely Antarctic suborder Notothenioidei, focus on three Sub-Antarctic species that differ greatly in their circumpolar distributions and display a strongly conserved karyotype consisting entirely of telocentric chromosomes, in agreement with the previously published hypothesis that the bovichtid karyotypes is the basal state for nototheniaid fishes.
Aspects of the morphology of phyletically basal bovichtid fishes of the Antarctic suborder Notothenioidei (Perciformes)
Histology indicates that Balushkin’s antesupracleithral organ is the thymus, a lymphoid organ that involutes with age in notothenioids, and a new ocular character complex first recognized here reinforces the phyletically basal position of bovichtids.
Phylogenetic analysis of Antarctic notothenioid fishes based on two-dimensional gel electrophoresis
The phylogenetic analyses showed that Gymnodraco acuticeps (Bathydraconidae) and Champsocephalus gunnari (Channichthyidae) composed a sistergroup, and that the family Nototheniidae was paraphyletic.
Genome enablement of the notothenioidei: genome size estimates from 11 species and BAC libraries from 2 representative taxa.
The results indicate that evolution of phylogenetically derived notothenioid families, [e.g., the icefishes (Channichthyidae], was accompanied by genome expansion, and sets the stage for expanded analysis of the psychrophilic mode of life.


Molecular evolution at subzero temperatures: mitochondrial and nuclear phylogenies of fishes from Antarctica (suborder Notothenioidei), and the evolution of antifreeze glycopeptides.
The age of the radiation of notothenioid fishes appears to be too low to agree with this date of origin and might instead suggest a younger age (10-15 Mya), and the low level of detected mtDNA variation would agree with the traditional old-age estimate if an extremely slow rate of mtDNA evolution is postulated for this group.
A 28S rRNA-based phylogeny of the gnathostomes: first steps in the analysis of conflict and congruence with morphologically based cladograms.
In maximum parsimony trees, nodes congruent with those of the morphologically based cladogram were found to be robust (chondrichthyans, neopterygians, euteleosteans), but some expected monophyletic groups were not finding to be so (lissamphibians, tetrapods, osteichthyans).
The Suborders of Perciform Fishes
The question of whether to include certain groups in or exclude them from the Perciformes is certainly moot, so the old perciform boundaries of Regan (1929) are followed, including the exclusion of the callionymoid fishes.
Study of the monotypic fish family Pholidichthyidae (Perciformes)
Aspects of the osteology, cranial nerves 5, 7, 9 and 10, lateral-line canals, free lateralis organs and miscellaneous anatomical features of Pholidichthys leucotaenia are described and illustrated.
A revision of Bovichtus Cuvier, 1831 (Pisces: Bovichthyidae) from Australasia, with description of a new deepwater species from the New Zealand Subantarctic
B. oculus, described from a specimen taken on the Campbell Plateau in the New Zealand Subantarctic, is the first known deep water Bovichtus species and differs from all congeners in having a very large eye and has a patch of ctenoid scales on the body behind the pectoral fin base.
Comments on Hennig's “Phylogenetic Systematics” and its Influence on Ichthyology
Recent work in systematic ichthyology indicates progress toward a phylogenetic classification in the Darwin-Hennig sense, and among other taxonomists, Hennig (1966, 1969, 1971; also Schlee, 1971) has written on the subject of methods and purposes.
Can the Cambrian explosion be inferred through molecular phylogeny
It is observed that the major lines of triploblast coelomates (arthropods, molluscs, echinoderms, chordates...) are very poorly resolved i.e. the nodes defining the various clades are not supported by high bootstrap values.
Species sampling has a major impact on phylogenetic inference.
It is empirically demonstrated that 4- to 24-species-trees are highly sensitive to species sampling: the inferences obtained from subsets of 4, 8, 16, or 24 species are not congruent with the whole set of 31 species.

    Cladistics : the international journal of the Willi Hennig Society
  • 1989
Cladistics has developed relatively free from entangling controversies about evolutionary models, most of which impinge upon systematics at the species level or at sub-specific levels and the initial question is whether these notions apply to species and, if so, in what way.
The complete nucleotide sequence of mouse 28S rRNA gene. Implications for the process of size increase of the large subunit rRNA in higher eukaryotes.
The complete nucleotide sequence of the mouse 28S rRNA gene is determined and it is indicated that the potential for major variations in size during the evolution has been restricted to a unique set of a few sites within a largely conserved secondary structure core.
