Puny males punch above their weight to preserve genetic diversity in a declining Atlantic salmon population.

abstract：:When studying selection during adaptation to novel environments, researchers have often paid little attention to an organism's earliest developmental stages. Despite this lack of attention, early life history traits may be under strong selection during colonization, as the expression of adaptive phenotypes at later po...
