The levels of six metals were determined in M. edulis collected from five sites on the south-eastern Australian coast. On a wet weight basis, levels (�g g-1) were: Pb, 1.68-4.15 ; Cu, 1.62-3.77; Cr, 2.27-3.83; Ni, 1.41-3.49: Cd, 0.39-0.63; and Zn, 20.64-40.38. On the basis of metal levels, Eden and Jervis Bay were less suitable as sites for mussel culture than Batemans Bay, Lakes Entrance and Merimbula.

Galeatylinae, a new subfamily in the Atylidae, for Galeatylus coripes new genus and species, is reported from the Bass Strait in the south-east of Australia. This is the first record of the Atylidae from Australia.

Total mercury concentrations in wing muscle of 10 species of waterfowl (Anatidae) collected during 1977 and 1978 in south-eastern Australia ranged from 0.08 � 0.04 (mean � SD) g g-1 wet weight in Australian shelduck Tadorna tadornoides and Pacific black duck Anas superciliosa, to 0.17 � 0.08 g g-1 in freckled duck Stictonetta naevosa. No significant differences in concentrations of mercury in muscle were found between sexes or between juvenile and adult birds. Total mercury concentrations in feathers were 3.01 � 0.09 g g-1 dry weight in Pacific black duck and 3.27 � 1.11 g g-1 in grey teal Anas gibberifrons. A significant positive correlation (r= 0.7783; P<0.01) was found between mercury concentrations in wing muscles and feathers of Pacific black duck.

In March 1977 one wing was collected from each duck of 12 species from 10 sites in south east Australia. Feathers were removed and the wing was ground for estimation of organochlorine residues. In 1978 there were 25 whole male Pacific black ducks (Anas superciliosa) analysed. Total DDT ranged from 0.03 to 316.1/106 wet weight between individual Pacific black duck wings and from 0.02 to 15.10/106 in pooled samples of wings for each species. There were significant positive relations between total DDT residue in wing and those in liver, brain, breast muscle and fat of individual Pacific black ducks. Residues may be important in breeding of ducks and because the ducks are shot and eaten by man.

In south-eastern Australia, the greater long-eared bat (Nyctophilus timoriensis) has been rarely captured and is considered uncommon, although large areas within its range have received little survey effort. We collate existing capture records and present new data on N. timoriensis captures from recent fauna inventory surveys across the western slopes and plains of New South Wales (NSW). From 1628 trap nights at 39 study areas, 118 N. timoriensis were captured out of a total of 8266 bats. In larger remnants in the Brigalow Belt South Bioregion, N. timoriensis was captured at a rate of 0.1 to 0.6 per trap night and made up 7 to 9% of bat captures. This was approximately an order of magnitude greater than in other study areas throughout western NSW. There were no captures from the Darling Riverine Plains Bioregion. These surveys show that the large vegetation remnants of Goonoo, Pilliga West and Pilliga East study areas are a distinct stronghold in the distribution of the south-eastern form of N. timoriensis.

The first monographic account of the south-eastern Australian representatives of the Corallinaceae, subfamily Mastophoroideae (Corallinales, Rhodophyta) is presented. The Mastophoroideae contains eight extant genera, four of which [Hydrolithon, Mastophora, Neogoniolithon, Pneophyllum] were confirmed to occur in south-eastern Australia. Hydrolithon is represented by six species (H. farinosum, H. improcerum, H. munitum, H. onkodes, H. rupestre and H. samoënse). Pneophyllum is represented by three species (P. coronatum, P. fragile and P. submersiporum) while Mastophora and Neogoniolithon are represented by a single species each (Mastophora pacifica and Neogoniolithon brassica-florida). Morphological and anatomical accounts are provided, including keys to genera and species, comparisons with related south-eastern Australian mastophoroid species, information on distribution, seasonality, habitat and nomenclature. Brief biogeographical comparisons between south-eastern Australia and other Australasian regions are also made.

Dryland salinity is considered a significant and increasing threat to sustainable land management and biodiversity across large parts of temperate Australia. However, there is little information on the extent of this threat to terrestrial ecosystems in south-eastern Australia. This paper provides a quantitative assessment of the extent of dryland salinity in remnant native woody vegetation in the agriculture-dominated landscape of the Boorowa Shire located in the South West Slopes bioregion of south-eastern Australia. The amount and type of native woody vegetation in the Boorowa Shire affected by dryland salinity was assessed by analysing the extent of overlap between the following three spatial data layers: (1) woody vegetation mapping derived from high-resolution satellite imagery, (2) existing vegetation community mapping predicted from field data and expert opinion and (3) existing dryland salinity outbreak mapping derived from air photo interpretation and filed verification. There were more than 6000 patches of salt outbreak in woody vegetation in the Boorowa Shire, 383 (6%) of which were 1 ha or larger in area. Almost 2000 ha of woody vegetation were affected by dryland salinity, representing ~3% of the extant native woody vegetation in the Boorowa Shire. The vegetation type with the largest total area affected by dryland salinity was yellow box (Eucalyptus melliodora Cunn. Ex Schauer)–Blakely’s red gum (E. Blakelyi Maiden) woodland. As a proportion of their current extent, vegetation communities lower in the landscape were significantly more affected than those higher up the topographic sequence, with 14% of riparian communities and nearly 6% of yellow box–Blakely’s red gum woodland exhibiting symptoms of dryland salinity. About 1% of white box (E. albens Benth) woodland, and of hill communities which are on mid- and upper slopes, were affected. The pattern of salinity outbreaks in relation to landscape position and vegetation type is significant for biodiversity conservation because the vegetation communities most affected by salinisation are those most heavily cleared and modified post-European settlement. Throughout the South West Slopes of New South Wales, remnants of riparian communities and yellow box–Blakely’s red gum woodland are highly cleared, fragmented and degraded. Dryland salinity represents an additional threat to these vegetation communities and their component species. Salinisation of woodland ecosystems poses significant problems for land managers. The long-term viability of these woodland remnants needs to be considered when allocating limited public funds for woodland conservation, whether on private land or in formal reserves.
