Infrared spectra from Hormosira banksii germlings Our previous microscopic observations, as well as previous studies on the formation of the adhesive mucilage [ 61 ], indicate that a connective layer of the order of a couple of micrometres thick is being produced between … Field surveys undertaken by Manning (1979) between 1975 and 1976 showed that, within 12 months of the commencement of discharge, the area occupied by Hormosira banksii in a study site at Boags Rocks had been reduced by 75% and, with the exception of holdfast remains, Durvillaea potatorum had disappeared completely. Upper intertidal levels are occupied by species such as Porphyra columbina , the karengo, that tolerate long exposure to air, light, and rain.

The Hormosira is restricted to the lower portion of the mangrove zone, which in this region fringes a well-developed salt marsh. Adult frond growth rate in the mid-platform pools, measured in situ, was highest in autumn but similar in the other seasons. Hormosira could tolerate full summer sunlight, water temperatures of up to 40°C, 140 psu (four times the strength of seawater) but not dehydration.

In the mangrove swamps of Botany Bay, there is an extensive development of free-floating Hormosira banksii. It is abundant on low-energy rocky reefs at midtide levels, where it outcompetes other algal species due to its high tolerance to desiccation.This is because it has a slimy layer that conserves moisture. Service, AVH: Adult frond growth rate in the mid-platform pools, measured in situ, was highest in autumn but similar in the other seasons. This brown alga grow in Point Lonsdale tide pools. Morphological variation was quantified on two spatial scales (tidal gradient versus latitudinal gradient) and the performance tested (relative water content and photosynthetic efficiency) of morphological variants during heat and desiccation stress. 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. Compared with other fucoids, growth was slow. Survivorship was Slobodkin’s Type IV, with few plants reaching 4 years but high longevity after that, due to the establishment of a holdfast which could regenerate new fronds. Durvillea antarctica, the bull kelp, is a species on rough coasts, and Hormosira banksii, the necklace seaweed, grows only where it is sheltered from heavy seas. In summer, however, in pools at the edge of the reef, often flushed by waves, the growth rate was as fast in summer as in autumn, either because of better provision of scarce nutrients or because of less inhibition by high temperature. Dehydration caused inter-annual variation in cover and in the total number of plants present, but with no overall trend over 12 years. Non-vascular – Native.
