Selection on offspring size and contemporary evolution under ocean acidification
Ocean acidification may have deleterious effects on many species, but anticipating long-term changes in the abundance of populations will require an understanding of ocean acidification as an evolutionary force. Here I show that ocean acidification alters natural selection on offspring size and is l...

Ocean acidification may have deleterious effects on many species, but anticipating long-term changes in the abundance of populations will require an understanding of ocean acidification as an evolutionary force.
