It is really exciting to be here on Isla navarino studying fish and the relationship between the native and exotic species. We have started sampling streams on the island and we are already seeing a dichotomous distribution between the presence of the natives and the presence of exotics. It appears that the introduced trout has eradicated the presence of the native galaxiid (G. maculaus) in most streams, but there are some streams dominated by galaxiids where only a few small trout are present. This is exciting to see and I look forward to sampling many more sites to find out what environmental mechanisms are related to this distribution. I´ll keep you posted.
Talk to you soon,
