Digestion in sea urchin larvae impaired under ocean acidification
Larval stages are considered as the weakest link when a species is exposed to challenging environmental changes1, 2. Reduced rates of growth and development in larval stages of calcifying invertebrates in response to ocean acidification might be caused by energetic limitations3. So far no informatio...
