Genomic evidence is increasingly underpinning that hybridization between taxa is commonplace, challenging our views on the mechanisms that maintain their boundaries. Here, we focus on seven catadromou
Biological invasions and introgressive hybridisation are major drivers for the decline of native freshwater fish. However, the magnitude of the problem across a native species range, the mechanisms sh
Hybridisation and introgression can dramatically alter the relationships among groups of species, leading to phylogenetic discordance across the genome and between populations. Introgression can also
