Mussel adaptation could help them fight effects of climate change

This article originally featured in The Skylark’s newsletter and was written as a condensed news in brief.

An existing genetic variation in natural populations of Mediterranean mussels allows them to adapt to declining pH levels in seawater. The change in sea acidification is a major effect of global carbon emissions. However a new study by biologists from the University of Chicago shows that mussels can grow smaller shells to combat the effects and therefore maintain the same survival rates. The hope is that mussels with this genetic variation already exist in the wild population and could pave the way for the species surviving future changes.
