Lise Marty, Ulf Dieckmann, Bruno Ernande: “Fisheries-induced neutral and adaptive evolution in exploited fish populations and consequences for their adaptive potential”
The paper presents a theoretical study on the interplay between neutral and adaptive evolution in life-history traits caused by fishing, using an individual-based eco-genetic model with gametic inheritance. The model includes neutral and functional loci. We find that evolutionary recovery is hampered by an association of weak selection differentials with reduced additive genetic variances and that the contribution of fisheries-induced selection to the erosion of functional genetic diversity clearly dominates that of genetic drift only for the traits related to maturation. Together, our results highlight the importance of taking into account population genetic variability in predictions of eco-evolutionary dynamics
