This study examined the attachment response of Balanus amphitrite larvae to bacteriadominated biofilms originating from 4 sites of varying environmental conditions in the intertidal region of subtropical Hong Kong waters and during 2 seasons (winter and summer), under both laboratory and field conditions. Using multiple fingerprinting techniques (terminal restriction fragment length polymorphis...

The barnacle Balanus ( = Amphibalanus) amphitrite is a major marine fouling animal. Understanding the molecular mechanism of larval settlement in this species is critical for anti-fouling research. In this study, we cloned one isoform of p38 MAPK (Bar-p38 MAPK) from this species, which shares the significant characteristic of containing a TGY motif with other species such as yeast, Drosophila a...

The barnacle Balanus amphitrite Darwin is a dominant intertidal and major fouling organism. As its life cycle includes both sessile and pelagic phases, adaptation is a necessity to tolerate harsh conditions that are faced in the intertidal and pelagic environment. A downward trend in dissolved oxygen levels in coastal areas has been recently observed, which would have a more prominent effect on...

The effects of sublethal concentrations of phenol and cadmium on the phototactic responses of the stage II nauplii of the barnacle Balanus amphitrite were investigated. Increased toxicant concentrations caused a reduction in phototactic responses. Balanus amphitrite nauplii exposed to nominal phenol concentrations of 100 ppm and higher for 1–12 h failed to exhibit phototactic responses, while l...
