Climate change threatens Western Australia's southwest biodiversity hotspot, endangering ancient freshwater fish populations.

Climate change poses a threat to unique Australian regions, particularly Western Australia's southwest, which is home to a high biodiversity and experiencing habitat loss and increasing temperatures and dryness. A new study shows that climate stability in the past allowed ancient populations of small freshwater fish to survive, but this stability is now at risk. Urgent conservation efforts are needed to protect this biodiverse region, one of Australia's two biodiversity hotspots.
