Rapid turnover of sex chromosomes is associated with speciation in Neotropical armored catfish Harttia (Siluriformes, Loricariidae)

Abstract Background The Neotropical armored catfish genus Harttia is an exceptional model for studying sex chromosome evolution, as it harbors the highest diversity of multiple sex chromosome systems known among fishes. However, the evolutionary history of these systems and their...

Dual northward overseas radiation from Japanese islands shaped the phylogeography of North-East Asian tree frog

The tree frog Dryophytes japonicus has a broad geographic distribution in northeastern Asia, comprising two major genetically divergent clades whose geographic boundary is located within the Japanese mainland. However, the evolutionary and adaptive mechanisms underlying this wide...

Genomic predisposition is associated with the direction of sex chromosome evolution

Sex chromosome evolution is among the most dynamic genomic innovations in vertebrates, yet why some lineages evolve XY while others evolve ZW remains unclear. Using chromosome-level genomes from 19 geckos, we found that gecko sex chromosomes originated independently from 16 ances...
