“…The exposed coasts of Tasmania were dealt with by Bennett & Pope (1960), who found great similarities with shores of southern Victoria. Tasmanian shores have a great development of lichens at the top of the shore and the upper mid-shore regions of the coldest parts of the coast have no barnacles and are very bare.…”

Experiments in intertidal and subtidal rocky marine habitats in temperate Australia have identified the effects of various biological and physical factors on algal assemblages. In intertidal habitats, these involve micro-and macro-algae and grazing by gastropods. In subtidal habitats, interactions among micro-and macro-algae, echinoids, gastropods, micro-invertebrates and sessile invertebrates have been studied. Experimental studies on physical disturbances of algal assemblages have focussed on the effects of desiccation and storms. Most studies have not considered more than one spatial or temporal scale. Few have been concerned with seasonal influences and fewer have been concerned with variation from year to year. Most of the work lacks applicability to biogeographic comparisons. More experimental work across a variety of spatial and temporal scales is required to determine significant biological and physical processes affecting structure of algal assemblages across broad areas of temperate Australia.

“…Contrary, juveniles of S. pugilus, S. gigas and S. costatus were reported to be found together with adults (Brownell, 1977). Habitat shift with growth has been known also in other intertidal and subtidal gastropods, e.g., Purpura lapillus (Moore, 1938), Melarapha praetermissa and M. unifasciata (Bennett & Pope, 1960), Decathais o~bita (Phillips, 1969), Tegulafunebralis (Paine, 1969), and Omphalius pfeijferi (Horikawa & Yamakawa, 1982). But in these works the reason for the situation has not been clarified decisively, though Moore pointed out the diet difference between juveniles and adults as the reason by providing some evidence.…”

Spatial distribution and growth of the gastropod Strombus luhuanus were investigated in the shallow waters of Shirahama, Japan. Newly settled juveniles smaller than 25 mm in shell length were found mainly on the rock flat shallower than ca. 5 m, where few adults were found. From O+ to 1 +year, they migrated downward to the fringe of rock and its adjacent areas, as they grew up to 40 mm in shell length, and then merged to the adult populations. At the age of 2+ years, they attained to 40-60 mm in shell length and some of them migrated offshore afterwards. Maturity and thickening of shell-lip usually occurred at the age of 2+ years or older. Adults showed seasonal changes in their distribution pattern. In winter they aggregated on the sand-pebble and near the fringe of rock, while from late spring to autumn they extended their distribution over sand and mud areas, offshore and inshore. Only in summer, many adults appeared on the sand-pebble area near the shoreline, being concurrent with coupling and spawning. S. luhuanus, thus, use the various substrata as their habitat, according to the life stages.

“…Additional data were collected at sheltered coastal sites at Maria Island and the Kent Group in Tasmania, and at the entrance to Port Phillip Heads in Victoria. Tasmania and Victoria comprise a single biogeographic region (the Maugean province, sensu Bennett and Pope, 1960), hence sites studied within this region should access much the same species pool. Additional comparable data from sheltered embayments in New South Wales (Jervis Bay Heads), South Australia (entrance to St Vincents Gulf) and south-western Western Australia (Jurien Bay) were also included in an analysis of species' depth distributions (Edgar et al, , 2003(Edgar et al, , 2006.…”

Biotic affinities of rocky reef fishes, invertebrates and macroalgae in different zones of the Port Davey marine protected area, south‐western Tasmania

ABSTRACT1. Assemblages of fishes, invertebrates, and macroalgae showed strong and predictable distributional patterns within the newly declared Port Davey marine protected area (MPA) in south-western Tasmania. Biotic assemblages in the eastern estuarine section of the MPA within Bathurst Channel were extremely anomalous, both in relation to biota elsewhere in the Port Davey region and also to those present along the wider Tasmanian and Australian coasts. Much of this variation was due to the phenomenon of deepwater emergence, with species in 5 m water depth in eastern Bathurst Channel possessing a mean maximum recorded depth of 200 m, compared witho80 m for the same metric when calculated for sites studied elsewhere around Australia. Deepwater emergence in Bathurst Channel was particularly notable for sessile organisms, although also evident among fishes and mobile macro-invertebrates.2. Quantitative baseline surveys of reef-associated species were undertaken at sites interspersed among MPA management zone types and biotic community types, thereby providing an appropriate benchmark for assessing ecological changes in different management zones within the Port Davey region through the long term. Distinctive biota present in eastern and western Bathurst Channel, and eastern Port Davey, are well protected within 'no-take' sanctuary zones; however, a bias in location of sanctuary zones towards areas with little fishery resources resulted in less protection for the western Port Davey biota, which also extends along the open coast. Although the lack of high level protection for sites with fishery resources detracts from conservation goals, the Port Davey MPA nevertheless represents a major advance in environmental protection because the ecologically unique, fully protected locations are a necessary inclusion within any comprehensive Australian MPA network.
