Method Primary source abstract: "To further understand how variations of the acid-base balance affect silicon metabolism and theca formation, [investigators] developed novel imaging techniques to measure the dynamics of valve formation."
Comments P.230 right column bottom paragraph: "Cytoplasmic pH in another diatom, Thalassiosira weissflogii, varied between 7.2 and 7.5 over the range of ocean pH (7.8–8.4) (primary source) and is generally similar to the cytoplasmic pH of other algae (Raven and Smith 1978, Anning et al. 1996, Braun and Hegemann 1999)."
