Genetically based population divergence in overwintering energy mobilization in brook charr (Salvelinus fontinalis).

Abstract excerpt

Investigating the nature of physiological traits potentially related to fitness is important towards a better understanding of how species and/or populations may respond to selective pressures imposed by contrasting environments. In northern species in particular, the ability to mobilize energy reserves to compensate for the low external energy intake during winter is crucial. However, the phenotypic and genetic...
