Molecular systematics of the African electric fishes (Mormyroidea: teleostei) and a model for the evolution of their electric organs.
TLDR
A reconstruction of electrocyte evolution on the basis of the best-supported topology suggests that electrocytes with penetrating stalks evolved once early in the history of the mormyrids followed by multiple paedomorphic reversals to electrocyces with non-penetrating stalks.
Interrelationships of the 11 gasterosteiform families (sticklebacks, pipefishes, and their relatives): a new perspective based on whole mitogenome sequences from 75 higher teleosts.
TLDR
The resultant phylogenies indicated explicitly that previously recognized members of Gasterosteiformes had diverged basally within the Percomorpha into three different clades with the following subgroups: Syngnathoidei, Gasterosomidae, and Indostomidae.
Phylogenetic utility of the first two introns of the S7 ribosomal protein gene in African electric fishes (Mormyroidea: Teleostei) and congruence with other molecular markers
TLDR
S7 data provide additional support for a number of clades recovered in the earlier molecular studies, some of which conflict with current mormyrid taxonomy, and phylogenetic results strengthen recent hypotheses concerning the evolution of electric organ structure in these fishes.
Phylogenetic relationships among anchovies, sardines, herrings and their relatives (Clupeiformes), inferred from whole mitogenome sequences.
TLDR
The mitogenomic data provide strong support for new clades within the Clupeidae, some of which are composed of members of more than one of the previously accepted subfamilies.
Simultaneous analysis of five molecular markers provides a well-supported phylogenetic hypothesis for the living bony-tongue fishes (Osteoglossomorpha: Teleostei).
TLDR
Maximum parsimony analysis of combined and equally weighted characters from the five molecular markers and Bayesian analysis provide a single, well-supported, hypothesis of osteoglossomorph interrelationships and show the group to be monophyletic.
Phylogenetic relationships of Acheilognathidae (Cypriniformes: Cyprinoidea) as revealed from evidence of both nuclear and mitochondrial gene sequence variation: evidence for necessary taxonomic
TLDR
This study provides the most comprehensive phylogenetic reconstruction of species relationships of the Acheilognathidae based on partitioned maximum likelihood and Bayesian methods using DNA sequence variation of nuclear and mitochondrial genes on 41 species, several subspecies and three undescribed species.
Sexual Signal Evolution Outpaces Ecological Divergence during Electric Fish Species Radiation
Natural selection arising from resource competition and environmental heterogeneity can drive adaptive radiation. Ecological opportunity facilitates this process, resulting in rapid divergence of
Molecular phylogenetics and the evolution of antarctic notothenioid fishes.
The monophyly of the antarctic fish suborder Notothenioidei and the monophyly of its earliest family the Bovichtidae have been investigated with 12S and 16S mitochondrial DNA sequences. New data from
EVOLUTIONARY ORIGIN AND EARLY BIOGEOGRAPHY OF OTOPHYSAN FISHES (OSTARIOPHYSI: TELEOSTEI)
TLDR
The origin and early diversification of this clade is reexamine based on a comprehensive time‐calibrated, molecular‐based phylogenetic analysis and event‐based approaches for ancestral range inference of lineages, which demonstrate Siluriformes is never sister to Gymnotiformes and Characiformes are most likely nonmonophyletic.
Molecular systematics of the gonorynchiform fishes (Teleostei) based on whole mitogenome sequences: implications for higher-level relationships within the Otocephala.
TLDR
The phylogeny of the Gonorynchiformes was investigated using whole mitogenome sequences from 40 species and it was confirmed that the paedomorphic species Cromeria nilotica and Grasseichthys gabonensis belong to the family Kneriidae; however, the two species together did not form a monophyletic group.
