As climate change accelerates, a central question for many species is whether their evolutionary response can keep pace with environmental shifts. A new study focusing on a long-lived seabird suggests that for such species, the answer may be no. Because these birds reproduce slowly and have long generation times, the speed at which they can evolve is inherently limited.
The research indicates that the seabird's adaptive capacity is likely outpaced by the rate of climate-driven change in its habitat. This mismatch between evolutionary potential and environmental pressure raises the risk of population decline. The study underscores that even species with existing genetic diversity may not be able to adjust quickly enough to ensure long-term survival.
While the findings are specific to this seabird, they illustrate a broader challenge for long-lived species facing rapid environmental change. The authors note that conservation strategies may need to account for evolutionary limits, not just immediate ecological threats, when assessing extinction risk under future climate scenarios.
