Ketola et al.: "The role of environmental robustness in adapting to fluctuating environments might be smaller than anticipated"

Fluctuating environments are expected to select for individuals that have highest geometric fitness over the experienced environments. This leads to the prediction that genetically determined environmental robustness in fitness, and average fitness across environments should be positively genetically correlated to fitness in fluctuating environments. Our results based on genetic correlations show that average egg-to-adult viability across different constant thermal environments, and not the environmental robustness, was the most important factor for explaining the fitness in fluctuating thermal environments. Our results suggest that the role of environmental robustness in adapting to fluctuating environments might be smaller than anticipated.

Results from Quantitative genetic experiment by Ketola, Lopez-Sepulcre et al. titled "DOES ENVIRONMENTAL ROBUSTNESS PLAY A ROLE IN FLUCTUATING ENVIRONMENTS?" was recently published in Evolution.
