Results: (1) Greenlandic stickleback co-occurring with Arctic char are bigger and (2) have relatively smaller heads than when stickleback are alone in a lake.

When baby salmon emerge from the gravel, how far do they disperse to summer rearing grounds? We haven't known until now (at least at the population scale), because they're too small to tag. In a paper just out, we answered this question using parentage-based (genetic) tagging! tinyurl.com/39b2sfjd

Atlantic #salmon, brown #trout and their hybrids can be difficult to distinguish, especially at early life stages. This new DNA-based method can be used to screen lots of individuals to verify the species or detect hybrids! 🧪🐟
With a low-cost DNA extraction, it is less than 1 euro / sample.
