Arctic charr phenotypic responses to abrupt temperature change: an insight into how cold water fish could respond to extreme climatic events.

This study shows Arctic charr can rapidly change their head shape in response to a 4°C temperature increase, reducing phenotypic variation and resembling a benthivorous ecotype.

Convergence in form and function overcomes non-parallel evolutionary histories in a Holarctic fish

This study shows that parallel phenotypic evolution can occur through non-parallel genetic pathways in Arctic charr, with gene expression playing a key role in phenotypic similarity.
