Phylogenetic classification of bony fishes
BackgroundFish classifications, as those of most other taxonomic groups, are being transformed drastically as new molecular phylogenies provide support for natural groups that were unanticipated byExpand

Comprehensive phylogeny of ray-finned fishes (Actinopterygii) based on transcriptomic and genomic data
Significance Ray-finned fishes form the largest and most diverse group of vertebrates. Establishing their phylogenetic relationships is a critical step to explaining their diversity. We compiled theExpand

Reconstructing the lionfish invasion: insights into Greater Caribbean biogeography
Aim  Lionfish (Pterois volitans and P. miles) are popular ornamental fishes native to the Indo-Pacific that were introduced into Florida waters and are rapidly spreading and establishing throughoutExpand

Addressing gene tree discordance and non-stationarity to resolve a multi-locus phylogeny of the flatfishes (Teleostei: Pleuronectiformes).
Non-homogeneous processes and, in particular, base compositional non-stationarity have long been recognized as a critical source of systematic error. But only a small fraction of current molecularExpand

An evaluation of fossil tip-dating versus node-age calibrations in tetraodontiform fishes (Teleostei: Percomorphaceae).
Time-calibrated phylogenies based on molecular data provide a framework for comparative studies. Calibration methods to combine fossil information with molecular phylogenies are, however, underExpand

Fossil-based comparative analyses reveal ancient marine ancestry erased by extinction in ray-finned fishes.
The marine-freshwater boundary is a major biodiversity gradient and few groups have colonised both systems successfully. Fishes have transitioned between habitats repeatedly, diversifying in rivers,Expand

Apparent signal of competition limiting diversification after ecological transitions from marine to freshwater habitats.
Adaptive radiations are typically triggered when a lineage encounters a significant range of open niche space (ecological opportunity), stemming from colonisation of new areas, extinction ofExpand

Phylogenetic placement of enigmatic percomorph families (Teleostei: Percomorphaceae).
Percomorphs are a large and diverse group of spiny-finned fishes that have come to be known as the "bush at the top" due to their persistent lack of phylogenetic resolution. Recently, the broaderExpand

A time-calibrated, multi-locus phylogeny of piranhas and pacus (Characiformes: Serrasalmidae) and a comparison of species tree methods.
The phylogeny of piranhas, pacus, and relatives (family Serrasalmidae) was inferred on the basis of DNA sequences from eleven gene fragments that include the mitochondrial control region plus 10Expand
