As oceans absorb more carbon dioxide, they are becoming increasingly acidic and shifting the delicate balance that supports marine life.
As oceans absorb more carbon dioxide, they are becoming increasingly acidic and shifting the delicate balance that supports marine life. How species will cope with ocean acidification and the other consequences of global climate change is still very much unknown and could have sweeping consequences.
Researchers from the University of Washington School of Aquatic and Fishery Sciences have discovered that ocean acidification impacts the ability of some oysters to pass down “memories” of environmental trauma to their offspring.
The two papers were published in December in Ecological Applications and the Journal of Shellfish Research.
“Warming and acidifying oceans negatively influence many marine species. However, some species that live in extreme environments, such as the intertidal, may be more resilient than others to these changes,” said Laura Spencer, one of the two lead authors and a graduate student in aquatic and fishery sciences. “Some species may even be able to pass on memories of harsh conditions to their offspring, making them more capable of surviving in similarly harsh environments.”
