Story summary

Environmental DNA (eDNA) detects tropical fish in temperate Australian reefs not previously recorded, signaling climate-driven shifts.
Climate change has driven over 12,000 species to migrate to escape unfavorable conditions.
Researchers surveyed 2,000 km of Australia's coastline, pairing visual surveys with eDNA to reveal shifts.
The approach strengthens biodiversity tracking and clarifies climate impacts on marine life.
