Ocean acidification alters fish–jellyfish symbiosis

Symbiotic relationships are common in nature, and are important for individual fitness and sustaining species populations. Global change is rapidly altering environmental conditions, but, with the exception of coral–microalgae interactions, we know little of how this will affect symbiotic relationships. 245 more words

Reduced pH affects pulsing behaviour and body size in ephyrae of the moon jellyfish, Aurelia aurita

Our understanding of how reduced seawater pH affects the behaviour and growth of scyphozoan jellyfish is poor. Here, we investigated the effects of simulated Ocean Acidification (OA) (pH = 7.6 for 7 d) on pulsing behaviour (as an index of swimming behaviour) and aspects of the morphology of ephyrae of the moon jellyfish Aurelia aurita. 173 more words

Differences in the responses of three scleractinians and the hydrocoral Millepora platyphylla to ocean acidification

We tested the hypothesis that taxonomically diverse cnidarians display dissimilar responses to ocean acidification (OA), and did so by comparing the individual responses to OA of one hydrocoral and three scleractinians. 177 more words
