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).

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.
