Pre-fledgling oxidative damage predicts recruitment in a long-lived bird

Noguera, J. C., Kim, S.-Y. & Velando, A. Pre-fledgling oxidative damage predicts recruitment in a long-lived bird. Biology letters rsbl20110756 (2011).


Empirical evidence has shown that stressful conditions experienced during development may exert long-term negative effects on life-history traits. Although it has been suggested that oxidative stress has long-term effects, little is known about delayed consequences of oxidative stress experienced early in life in fitness-related traits. Here, we tested whether oxidative stress during development has long-term effects on a life-history trait directly related to fitness in three colonies of European shags Phalacrocorax aristotelis. Our results revealed that recruitment probability decreased with oxidative damage during the nestling period; oxidative damage, in turn, was related to the level of antioxidant capacity. Our results suggest a link between oxidative stress during development and survival to adulthood, a key element of population dynamics.
