Analysis of sequence variation in the mitochondrial and nuclear genes in Azygopterus corallinus showed that this species was genetically close to the group uniting the representatives of the families Zoarcidae, Neozoarcidae, and Anarhichadidae. The considerable genetic differences between A. corallinus and the members of the family Stichaedae, to which it was assigned earlier, are consistent with the divergence estimates between the other families of the suborder Zoarcoidei (Zaproridae… Expand
Genetic differentiation of species and taxonomic structure of the superfamily Stichaeoidea (Perciformes: Zoarcoidei)
These investigations suggest that the superfamily Stichaeoidea should include not only the families Sticaeidae, Pholidae, and Ptilichthyidae, but also the Zaproridae and Cryptacanthodidae, while the family Anarhichadidae should be excluded from it. Expand
Molecular phylogenetic reconstruction and taxonomic investigation of eelpouts (Cottoidei: Zoarcales) based on Co-1 and Cyt-b mitochondrial genes
The monophyletic origin of the families Zoarcidae and Anarhichadidae, as well as Neozoarcidae, previously related to Stichaeidae and recently revised Eulophiidae are demonstrated and Opisthocentrinae and Pholidae seem to constitute a valid family-level taxon. Expand
New osteological description of the genera Eulophias and Zoarchias (Perciformes, Zoarcoidei)
Osteological descriptions of Eulophias and Zoarchias are presented in detail for the first time and partially support those of a previous molecular analysis, but further systematic studies of Zoarcoidei are required. Expand


Position of neck banded blenny Leptostichaeus pumilus (Perciformes: Zoarcoidei) in the system of the suborder Zoarcoidei as inferred from molecular genetic data
Significant genetic differences between neck banded blenny and the family Stichaeidae correspond to the level of divergence between other families of the suborder Zoarcoidei (Zaproridae, Ptilichthyidae, Pholidae, Cryptacanthodidae, and Bathymasteridae). Expand
Genus Leptostichaeus and its position in the taxonomy of fishes (Perciformes: Zoarcoidei, Stichaeidae)
The genus Leptostichaeus is transferred into the group Azygopterinae, which is revalidated as a subfamily within the family Stichaeidae. Expand
Relationships and position of the genus Neozoarces of the subfamily neozoarcinae in the system of the suborder Zoarcoidei (Pisces, Perciformes) by molecular-genetic data
The results of investigations confirm the viewpoint suggested by Makushok (1961) who included, for the first time, the subfamily Neozoarcinae to the family Zoarcidae on the basis of comparative morphological investigation of these groups. Expand
Phylogenetic relationships among families of Gadiformes (Teleostei, Paracanthopterygii) based on nuclear and mitochondrial data.
The analysis of nuclear and mitochondrial DNA sequences for the most extensive taxonomic sampling compiled to date confirmed the monophyly of Gadiformes and most of the proposed families for the order, but alternative hypotheses of sister-group relationships among families were poorly resolved.

Multilocus analyses of an Antarctic fish species flock (Teleostei, Notothenioidei, Trematominae): phylogenetic approach and test of the early-radiation event.
Diversification rate analyses support the hypothesis of a period of rapid diversification during Trematominae history and only a few nodes in the hypothetical species tree were consistently resolved with various phylogenetic methods. Expand
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. Expand
In search of notothenioid (Teleostei) relatives
A clade that contains the sister group of notothenioids, the Percidae (perches), and a number of relatives is identified, and the interrelationships of its components and their distribution show that the Antarctic benthic fish fauna has at least three origins. Expand
Repeatability of clades as a criterion of reliability: a case study for molecular phylogeny of Acanthomorpha (Teleostei) with larger number of taxa.
This study represents the most extensive taxonomic sampling effort to date to collect new molecular characters for phylogenetic analysis of acanthomorph fishes, with new and reliable clades emerging from this study of the acanthomorphic radiation. Expand
Phylogeny of Trematomus (Notothenioidei: Nototheniidae) inferred from mitochondrial and nuclear gene sequences
This paper revisits the phylogenetic relationships of Trematomus using both increased taxon sampling and an expanded dataset which includes DNA sequences from two mitochondrial genes and one single-copy nuclear gene, and demonstrates that the addition of nuclear gene sequence data to mitochondrial data can enhance phylogenetic resolution and increase node support.

Phylogenetic utility of two existing and four novel nuclear gene loci in reconstructing Tree of Life of ray-finned fishes: the order Cypriniformes (Ostariophysi) as a case study.
A set of 6 previous and 22 new PCR/sequencing primers for RAG1, Rhodopsin and four novel nuclear markers from IRBP, E GR1, EGR2B and EGR3 are described that were developed through an approach making use of public genetic/genomic data mining for one of the ongoing tree of life projects aimed at understanding the evolutionary relationships of the planet's largest clade of freshwater fishes--the Cypriniformes.
