Here we look at life-history adaptation in the arctic charr in a high mountain environment with a particular emphazis on its life history strategies. As this is a marginal environment with regard to the number and variability of degree-days (i.e. the temperature sum), and the length and variability of the feeding season, the charr must trade-off energetic requirements to growth and gonad allocation, and potentially adopt a bet-hedging strategy. Thus, alternative life-history strategies may evolve in such harsh environments as compared to the founder population which exists in a very divergent lowland environment.
