Global warming and ocean acidification affect fertilization and early development of the sea urchin Paracentrotus lividus
Increasing values of atmospheric CO2 and consequent seawater warming, as well as progressive seawater acidification constitute stressors for marine populations that may induce migrations and even local extinctions. We evaluated the separated effects of (1) high predicted temperature levels and (2) l...
