Physiology mediates transcontinental radiations of freshwater fishes

The paper shows that saltwater tolerance enabled transcontinental freshwater fish radiations to disperse across marine barriers and diversify in freshwater ecosystems.

The macroevolutionary impact of an innovation reversal in ray-finned fishes

This paper shows how swim bladder loss in ray-finned fishes influenced diversification by enabling adaptation to deep sea and Southern Ocean environments, but also acted as a selective filter during past global warming events.

The largest radiations of freshwater fishes initiated at the Cretaceous-Paleogene boundary

This paper shows that the major freshwater fish clade Ostariophysi diversified rapidly after the Cretaceous-Paleogene extinction, with two freshwater invasions and rapid origination of major clades within five million years.

Genomic Distortion of Jawed Vertebrate Phylogeny

This study investigates how genomic evolution affects phylogenetic relationships and divergence times in jawed vertebrates, showing that rapid radiations and varying mutation rates obscure evolutionary timelines.
