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.

Pyrosequencing is applied for the study of plankton and protist diversity in lake Finsevatn. This lake has been influenced by human activity, particularly since the tourism came to this high-mountain location with the opening of the Oslo-Bergen railway in 1909. Scientific investigations since 1986 have revealed the diversity of the lake's phytoplankton by microscopy, but new technology supplies a much more diverse picture involving microbial parasites and previously unknown protists - some with relatives in marine environments - see Bråte et al. (2010), Shalchian-Tabrizi et al. (2011).
