Live fast, die old: oxidative stress as a potential mediator of an unexpected life‐history evolution

Abstract: Intraspecific latitudinal patterns in life history are well documented, yet underlying mechanisms of such patterns are poorly understood. To advance our insights in the evolution of latitudinal differences in two key traits, growth rate and lifespan, we evaluated the potential costs of rapid growth in terms of reduced adult lifespan, and the mediatory role of oxidative stress. We studied latitudinal differentiation in routine and experimentally increased (compensatory) larval growth rates, and in adult lifespa… Show more

“…This result was also mirrored in a similar artificial selection study using mice [ 44 ]. Further, insect genotypes with high intrinsic growth rates (and correspondingly high EE), and showing higher capacity for rapid growth following a period of food shortage, live longer and had more antioxidant enzymes, and tended to experience lower oxidative damage than genotypes with slow intrinsic growth rates [ 45 ].…”
