The combined effects of ocean acidification and warming on a habitat-forming shell-crushing predatory crab
In mid rocky intertidal habitats the mussel Perumytilus purpurarus monopolizes the substratumto the detriment of many other species. However, the consumption of mussels by the shell-crushing crab Acanthocyclus hassleri creates within the mussel beds space and habitat for several other species. This...

In mid rocky intertidal habitats the mussel Perumytilus purpurarus monopolizes the substratumto the detriment of many other species. However, the consumption of mussels by the shell-crushing crab Acanthocyclus hassleri creates within the mussel beds space and habitat for several other species. This crab uses its disproportionately large claw to crush its shelled prey and plays an important role in maintaining species biodiversity. This study evaluated the consequences of projected near-future ocean acidification (OA) and warming (OW) on traits of A. hassleri linked with their predatory performance. Individual A. hassleri were maintained for 10-16 weeks under contrasting pCO(2) (similar to 500 and 1400 mu atm) and temperature (similar to 15 and 20 degrees C) levels.
