Resilience of The Larval Slipper Limpet Crepidula Onyx to Direct and Indirect-Diet Effects of Ocean Acidification
Ocean acidification (OA) is known to directly impact larval physiology and development of many marine organisms. OA also affects the nutritional quality and palatability of algae, which are principal food sources for many types of planktonic larvae. This potential indirect effect of OA via trophic i...
