Nine exceptional radiations plus high turnover explain species diversity in jawed vertebrates

The uneven distribution of species richness is a fundamental and unexplained pattern of vertebrate biodiversity. Although species richness in groups like mammals, birds, or teleost fishes is often…
Rates of speciation and morphological evolution are correlated across the largest vertebrate radiation.
It is demonstrated that rates of species diversification are highly correlated with the rate of body size evolution across the 30,000+ living species of ray-finned fishes that comprise the majority of vertebrate biological diversity.
Did genome duplication drive the origin of teleosts? A comparative study of diversification in ray-finned fishes

The results suggest that the causes of diversification in large clades are likely to be complex and not easily ascribed to a single event, even a dramatic one such as a whole genome duplication.
Diversity versus disparity and the radiation of modern cetaceans

It is concluded that the signature of adaptive radiations may be retained within morphological traits even after equilibrium diversity has been reached and high extinction or fluctuations in net diversification have erased any signature of an early burst of diversification in the structure of the phylogeny.
DO REEFS DRIVE DIVERSIFICATION IN MARINE TELEOSTS? EVIDENCE FROM THE PUFFERFISH AND THEIR ALLIES (ORDER TETRAODONTIFORMES)

It is suggested that both intrinsic factors of reef habitat and extrinsic factors relating to the provincialization and regionalization of the marine biota during the Miocene played a role in shaping these patterns of diversity.
Iterative Ecological Radiation and Convergence during the Evolutionary History of Damselfishes (Pomacentridae)
- B. Frédérich, L. Sorenson, F. Santini, G. Slater, M. Alfaro

- 30 November 2012
Tests of the tempo of lineage diversification using a time-calibrated phylogeny including 208 species revealed that crown pomacentrid diversification has not slowed through time as expected under a scenario of a single adaptive radiation resulting from an early burst of diversification.
A Phylogenomic Perspective on the Radiation of Ray-Finned Fishes Based upon Targeted Sequencing of Ultraconserved Elements (UCEs)
A genomic perspective on longstanding questions regarding the diversification of major groups of ray-finned fishes is provided through targeted enrichment of ultraconserved nuclear DNA elements (UCEs) and their flanking sequence and reveals that sequence capture of UCE regions and theirFlanking sequence offers enormous potential for resolving phylogenetic relationships within ray- finned fishes.
A phylogeny of the families of fossil and extant tetraodontiform fishes (Acanthomorpha, Tetraodontiformes), Upper Cretaceous to Recent
The new phylogenetic hypothesis, together with stratigraphic and biogeographical data, is used to discuss scenarios of the origin and evolution of the major clades of the tetraodontiform order.
The effect of habitat on modern shark diversification
The new timetree suggests that the two major shark lineages leading to the extant shark diversity began diversifying mostly after the end‐Permian mass extinction: the squalimorphs into deepwater and the galeomorphs into shelf habitats.
A multi-locus timetree of surgeonfishes (Acanthuridae, Percomorpha), with revised family taxonomy.

- Biology, MedicineMolecular phylogenetics and evolution
- 1 July 2013
The most comprehensive time-calibrated, species-level hypothesis of the timing of Acanthuridae evolution based on 76% of the extant diversity and nine genes is presented and dissolving the genus Ctenochaetus is recommended, based on the large body of morphological evidence.
