A limit on the evolutionary rescue of an Antarctic bacterium from rising temperatures ...
Climate change is gradual, but it can also cause brief extreme heat waves that can exceed the upper thermal limit of any one organism. To study the evolutionary potential of upper thermal tolerance, we evolved the cold-adapted Antarctic bacterium Pseudoalteromonas haloplanktis to survive at 30°C, be...

Climate change is gradual, but it can also cause brief extreme heat waves that can exceed the upper thermal limit of any one organism.
