Description

Marine molluscs are vulnerable organisms that play a crucial role in determining the composition and dynamics of a system. Intensified anthropogenic pressures, such as ocean acidification and warming, have altered the equilibrium of some ecologically and economically important marine communities. Our knowledge on the isolated effects of these stressors is increasing, however their interactions are poorly understood, particularly during early life stages. This study analysed the combined effects of ocean acidification and temperature rise on the development of two sea hares, Aplysia dactylomela and Dolabella auricularia. Individuals were collected at Heron Island on the southern Great Barrier Reef, Australia. In situ experiments were performed to simulate six different scenarios of decreased pH and increased temperature, and to evaluate morphological and behavioural responses of embryos and larvae. We found that embryonic stages were less affected than larval stages, suggesting that the impacts of both stressors may only become evident after long periods of exposure.
