Molluscs on acid: gastropod shell repair and strength in acidifying oceans
The importance of 'top-down' regulation of assemblages by predators is well documented at a variety of spatial and temporal scales on rocky-shores. Predators have consumptive and non-consumptive impacts on their prey; however, much remains to be discovered about how climate change may affe...

The importance of 'top-down' regulation of assemblages by predators is well documented at a variety of spatial and temporal scales on rocky-shores. Predators have consumptive and non-consumptive impacts on their prey; however, much remains to be discovered about how climate change may affect predator-prey interactions and processes related to these interactions. We investigated the effect of predicted near-future ocean acidification on a molluscan defence mechanism: shell repair. We simulated non-consumptive damage by a durophagous (shell crushing) predator to 2 common intertidal gastropod species: Austrocochlea porcata and Subninella undulata.
