Filter-feeding bivalves are able to sense the presence of suspended food particles in the ambient water, and this sensitivity is reflected in the gape of the valves (Jorgensen 1975).
Next, in field studies we examined the interactions between water flow, near-bed phytoplankton biomass and valve gape opening-closing response times of mussels in a dense bed.
In another series of experiments, the valve gape opening-closing response of mussels caused by presence/absence of algal cells was also recorded during periods with continuous algal supply followed by starvation periods without algal supply.
On press freedom in China, Gapes declined to say if the committee members are going to discuss specific cases such as the case of Ching Cheong, a Singapore Strait Times reporter who has been under arrest since last August and is yet to be tried in court on espionage allegations.
On the balance of security in the region, especially China's relationship with the United States and Japan, Gapes said they will try to gather more information from the region as a whole.
