Vulnerability of red sea urchins to climate change depends on location

A new study of red sea urchins, a commercially valuable species, investigated how different populations respond to changes in their environments. The results show that red sea urchin populations in Northern and Southern California are adapted to their local conditions but differ in their vulnerability to the environmental changes expected to occur in the future due to global climate change and ocean acidification. Red sea urchin populations in Southern California may be more vulnerable to climate change than those in Northern California. …read more
