Description
  • We describe the functional consequences of haemoglobin divergence between two British populations of the bank vole (Clethrionomys$glareolus), one that partially replaced the other during endVglacial colonization from mainland, to examine the possibility of adaptive processes in explaining the replacement. We determine the amino acid substitution of serine for cysteine in the beta haemoglobin chain as the mutation underlying the divergence between the two populations. We demonstrate that this mutation increases the tolerance of bank vole blood cells to oxidative stress. Because levels of oxidative stress correlate with a variety of physiological and pathological states, we argue that the mutation may have conveyed a competitive advantage over the first colonists, promoting the replacement.
