Along the east coast of Australia, the alga can also persist in mangroves as a free-living form trapped amongst pneumatophores. There was an increase in the proportion of energy directed to photoinhibition (nonregulated nonphotochemical quenching) and a concomitant decrease in energy used to drive photochemistry and xanthophyll cycling (regulated nonphotochemical quenching).

Embryo growth was reduced at 28°C, but significant interactions between male genotype and temperature in one population indicated the presence of genetic variation in thermal sensitivity. pt. Biology. Intertidal Zonation to King George Sound in Western Australia. Neptune's necklace, Hormosira banksii, also known as sea grapes or bubbleweed, is a species of seaweed found in Australia and New Zealand.It is a common seaweed found in rock pools at mid-tide levels and is characterised by strings of olive-brown hollow beads. Beads appear spotted/bumpy (conceptacles). They also have modified cells that grip onto rocks, this adaptation also supports the few numbers of Neptune's necklace at high tide as there are rocks that they can cling on to.
