Data from: A phylogenomic framework for pelagiarian fishes (Acanthomorpha: Percomorpha) highlights mosaic radiation in the open ocean

Matthew Friedman, Kara Feilich, Hermione Beckett, Michael Alfaro, Brant Faircloth, David Černý, Masaki Miya, Thomas Near & Richard Harrington
The fish clade Pelagiaria, which includes tunas as its most famous members, evolved remarkable morphological and ecological variety in a setting not generally considered conducive to diversification: the open ocean. Relationships within Pelagiaria have proven elusive due to short internodes subtending major lineages suggestive of rapid early divergences. Using a novel sequence dataset of over 1000 ultraconserved DNA elements (UCEs) for 94 of the 286 species of Pelagiaria (more than 70% of genera), we provide...

Data from: MiFish, a set of universal PCR primers for metabarcoding environmental DNA from fishes: detection of more than 230 subtropical marine species

We developed a set of universal PCR primers (MiFish-U/E) for metabarcoding environmental DNA (eDNA) from fishes. Primers were designed using aligned whole mitochondrial genome (mitogenome) sequences from 880 species, supplemented by partial mitogenome sequences from 160 elasmobranchs (sharks and rays). The primers target a hypervariable region of the 12S rRNA gene (163–185 bp), which contains sufficient information to identify fishes to taxonomic family, genus and species except for some closely related congeners. To test versatility...

Ultraconserved elements data for Amarsipus and Pelagiaria

Richard Harrington, Matt Friedman, Masaki Miya, Thomas Near & Matthew Campbell
Amarsipus carlsbergi is a rare mesopelagic fish distributed in the Indian and Pacific Oceans, and is the only species classified in the family Amarsipidae. Since its description in 1969, phylogenetic hypotheses have varied regarding its relationship with other percomorph lineages, but most have indicated a close relationship with the traditional suborder Stromateoidei. Molecular phylogenies place families previously classified in Stromateoidei within a diverse clade– Pelagiaria– that includes fishes such as tunas, cutlassfishes, and pomfrets. A...

Data from: Evolutionary origin of the Scombridae (tunas and mackerels): members of a Paleogene adaptive radiation with 14 other pelagic fish families

Masaki Miya, Matt Friedman, Takashi P. Satoh, Hirohiko Takeshima, Tetsuya Sado, Wataru Iwasaki, Yusuke Yamanoue, Masanori Nakatani, Kohji Mabuchi, Jun G. Inoue, Jan Yde Poulsen, Tsukasa Fukunaga, Yukuto Sato & Mutsumi Nishida
Uncertainties surrounding the evolutionary origin of the epipelagic fish family Scombridae (tunas and mackerels) are symptomatic of the difficulties in resolving suprafamilial relationships within Percomorpha, a hyperdiverse teleost radiation that contains approximately 17,000 species placed in 13 ill-defined orders and 269 families. Here we find that scombrids share a common ancestry with 14 families based on (i) bioinformatic analyses using partial mitochondrial and nuclear gene sequences from all percomorphs deposited in GenBank (10,733 sequences) and...

Data from: Molecular phylogeny of the cyprinid tribe Labeonini (Teleostei: Cypriniformes)

Lei Yang, M. Arunachalam, Tetsuya Sado, Boris A. Levin, Alexander S. Golubtsov, Jörg Freyhof, John P. Friel, Wei-Jen Chen, M. Vincent Hirt, Raja Manickam, Mary K. Agnew, Andrew M. Simons, Kenji Saitoh, Masaki Miya, Richard L. Mayden & Shunping He
The cyprinid tribe Labeonini (sensu Rainboth, 1991) is a large group of freshwater fishes containing around 40 genera and 400 species. They are characterized by an amazing diversity of modifications to their lips and associated structures. In this study, a total of 34 genera and 142 species of putative members of this tribe, which represent most of the generic diversity and more than one third of the species diversity of the group, were sampled and...

Data from: Species selection favors dispersive life histories in sea slugs, but higher per-offspring investment drives shifts to short-lived larvae

Patrick J. Krug, Jann E. Vendetti, Ryan A. Ellingson, Cynthia D. Trowbridge, Yayoi M. Hirano, Danielle Y. Trathen, Albert K. Rodriguez, Cornelis Swennen, Nerida G. Wilson & Ángel A. Valdés
For 40 years, paleontological studies of marine gastropods have suggested that species selection favors lineages with short-lived (lecithotrophic) larvae, which are less dispersive than long-lived (planktotrophic) larvae. Although lecithotrophs appeared to speciate more often and accumulate over time in some groups, lecithotrophy also increased extinction rates, and tests for state-dependent diversification were never performed. Molecular phylogenies of diverse groups instead suggested lecithotrophs accumulate without diversifying due to frequent, unidirectional character change. Although lecithotrophy has repeatedly...
