Albatrosses Face Climate Crisis: Evolution Too Slow to Save Them, Study Reveals
- •A new study on Black-browed Albatrosses reveals that while natural selection can aid adaptation, it may not be fast enough to prevent population decline under severe warming scenarios.
- •Researchers used over 30 years of data from Black-browed Albatrosses on the Kerguelen Islands, combined with climate projections and an eco-evolutionary model.
- •Evolution can influence population future, with traits like wing length affecting survival, but its response has limits, especially for long-lived species.
- •The albatross's long generation time creates a dangerous mismatch, as climate conditions can change much faster than the species can adapt.
- •Limiting greenhouse-gas emissions could significantly reduce the projected extinction probability, giving evolutionary adaptation more time to work.
Key Questions Answered
No, when warming becomes too severe, evolutionary changes may not happen quickly enough to prevent population decline.
Researchers used more than 30 years of demographic and physical-trait data from albatrosses breeding on the Kerguelen Islands, combined with climate projections and an eco-evolutionary model.
Evolution works slowly across generations, creating a dangerous mismatch where climate conditions change much faster than a long-lived species can adapt.
