Phenotypic Plasticity in Economically and Ecologically Important Bivalves in Response to Changing Environments
… of acclimation, I found that stressors reduced shell strength and periostracum (outer shell layer) density. Only acidification affected lipids, and fatty acid content varied between treatments. I was the first to quantify microbial composition of a bivalve under multiple stressors and I found …

The interaction of acidification and warming on the South African abalone, Haliotis midae, and the potential for mitigation in aquaculture
… growth, spawning patterns, acid-base regulation, shell growth, morphology, shell strength and mineralogy over 12 months. This study also investigated the potential use of Ulva (Chlorophyta) as a mitigational tool to ameliorate acidified seawater, by photosynthetic carbon dioxide uptake, in a …

Aspects of stress with particular reference to mytilid mussels and their parasites
… in these mussels. Mastigocoleus sp., a shell boring cyanophyte, colonises Mytilus with prevalences from 1% to 94% and can reduce shell strength by 43%. The relationship between stress (amount of alga on the shell) and strain (degree of damage) is demonstrated: 61.8% of variation in …
