A long-held, but poorly tested, assumption in natural populations is that individuals disperse into new areas for reproduction are at a disadvantage compared to reproduce their natal habitat, underpinning the eco-evolutionary processes of local adaptation and ecological speciation. Here, we capitalize on fine-scale population structure dispersal events compare reproductive success dispersing captured same spawning ground four consecutive parent-offspring cohorts wild Atlantic salmon (Salmo...
Abstract In species with complex life cycles, history theory predicts that fitness is affected by conditions encountered in previous stages. Here, we use a 4‐year pedigree to investigate if time spent two distinct stages has sex‐specific reproductive consequences anadromous Atlantic salmon ( Salmo salar ). We determined the amount of years fresh water as juveniles (freshwater age, FW, measured years), and marine environment adults (sea SW, sea winters) on 264 sexually mature collected river...
Linking reproductive fitness with adaptive traits at the genomic level can shed light on mechanisms that produce and maintain sex-specific selection. Here, we construct a multigenerational pedigree to investigate selection maturation gene, vgll3, in wild Atlantic salmon population. The vgll3 locus is responsible for ~40% of variation (sea age first reproduction). Genetic parentage analysis was conducted 18,265 juveniles (parr) 685 adults collected same spawning ground over eight consecutive...
