Description
Jeffery Chan and co-authors compare gene patterns in goby fish in a 2026 study from Hong Kong and southern China. Some gobies swim between rivers and the sea, some never migrate, and dams can trap others in fresh water for good. The team asked how those life paths shape gene diversity and split.
Genome wide markers covered six groups of a non migrating kind and seven groups of a kind that can migrate. Groups that never migrate were deeply split, with low diversity that matched old river paths. Free migrating groups looked alike and held high diversity. Trapped groups split fast, with those behind tall dams most distinct after 58 to 106 years. Models of a group trapped 60 years ago showed gene flow near zero.
