Increasing acidification of the oceans is threatening populations of mussels

Leave a Comment
World populations of mussels can be threatened as climate change are making the oceans increasingly acidic. A new research has revealed that the mussels that form in acidic waters have more fragile shells.

The increase of carbon dioxide (CO2) in the atmosphere makes the oceans more acidic and causes a reduction of the concentration of minerals that the mussels need to develop their shells, indicate the scientists at the University of Glasgow, Scotland, who published the study in the journal of the Royal Society Interface.

The study further concluded that the mussels may have a built-in biological defense mechanism that drives the development of shells when water temperatures rise by about 2 degrees Celsius.

"What we discovered in the course of the investigation is that the highest levels of acidity in their habitats have a negative impact on the ability of mussels to develop their shells", indicate the researchers in a statement, quoting the Guardian.
