Data for the catches of sharks at each beach meshed in New South Wales are presented for the period from October 1972 to December 1990. High catch rates of sharks were observed at a number of these beaches. Comparison of the catches of sharks at each beach by means of hierarchical clustering and nonmetric multidimensional scaling revealed regional associations as well as some unusual relationships. Beaches at either end of each netted region (i.e. Newcastle, Sydney or Wollongong) tended to have higher catches than did beaches in the centre of each region. Hammerhead sharks (Sphyrna spp.) had significantly higher catch rates on long open beaches. Significantly higher catches of whaler (Carcharhinus spp.), white (Carcharodon carcharias), and tiger (Galeocerdo cuvier) sharks occurred when deeper water was closer to the beach. Limited biological and seasonal data are also presented for the 11 species or species groups: Sphyrna spp., Carcharhinus spp., Squatina austmlis, Heterodontus spp., Carcharodon carcharias, Galeocerdo cuvier, Carcharias taurus, Notorynchus cepedianus, Alopias spp., Isurus oxyrinchus and Orectolobus spp.

This paper contains descriptions of thirteen new Australian species of Scapheremaeus Berlese, 1910, belonging to the species groups Carinatus from New South Wales and Victoria (S. alisonae sp. nov., S. allmani sp. nov., S. nivalis sp. nov., S. tuberculosus sp. nov. and S. zephyrus sp. nov.), Patella from Western Australia and Tasmania (S. baylyi sp. nov. and S. tegulatus sp. nov.), Petrosus from New South Wales, Tasmania, Victoria and Western Australia (S. bulbosensillatus sp. nov., S. euthemellus sp. nov., S. minjambuta sp. nov., S. notoverrucatus sp. nov. and S. truncatus sp. nov.) and Emarginatus from Queensland (S. walteri sp. nov.), Only members of the predominantly Neotropical and Australasian Carinatus species-group have been described from Australia hitherto, and Australian species constitute a third of this group. The Patella species-group is mostly Afrotropical (four spp.), with one Palaearctic and three Australasian species, including the two new species described herein. The Petrosus species-group, previously known from three Palaearctic, two Oriental and one Neotropical species, is now dominated by five new Australian species described herein. The Emarginatus species-group contains one species each from Australia, New Zealand, Java and Cuba. A key to Australian species is provided. The genus Scapheremaeus contains some 112 species, and can beconsidered hyperdiverse by oribatid standards. Morphological traits are considered that may relate to the ecological diversification and adaptive radiation of Scapheremaeus, particularly those related to species living on leaves and stems within rainforest canopies.

The Relationship

Thirty common grasses from unfertilised sheep pastures of the Northern Tablelands of New South Wales were grouped according to their distribution about a sheep camp. The frequency and relative frequency of 16 of these grasses related to their distribution. It is argued that the distribution patterns detected can be attributed to stocking by sheep. The relationship between distribution, origin of the species, life cycle, life form and growing season were examined, and all were found to show statistically significant relationships. When the species were clustered using vegetative attributes which were significantly related to distribution, groups were formed which related more to taxonomy at tribal level than to distribution. Contingency analysis, relating the presence of the same attributes to species groups based on distribution pattern, showed that only photosynthetic mechanism and origin were related to that pattern, whereas all attributes, except origin, were related to tribe. Although individual characters are related to distribution and hence presumably to stocking, there is no single syndrome of characters related to distribution.

Over Time

The New South Wales (NSW) government has operated a program of netting beaches for the protection of swimmers and surfers against shark attack since 1937 in Sydney, and since 1949 in Newcastle and Wollongong. The scope and directives of the Shark Meshing Program have remained constant since its inception, with operational modifications in net specifications in 1972, changes in spatial deployment in 1972, 1987 and 1992, and the elimination of winter netting since 1989. This markedly increased meshing effort in 1972, and again in 1987. In the present study, we examine the trends in catch and effort for the period from 1950–1951 to 2009–2010 over this 200-km section of the NSW coast. Significant temporal trends in species, size and sex composition are described herein. Catches were consistently dominated by three shark taxa, hammerhead sharks (Sphyrna spp.), whaler sharks (Carcharhinus spp.) and Australian angel sharks (Squatina australis), although their relative contributions to catches varied over time. Catch per unit effort has significantly declined for five of the most abundant shark taxa over the study period, increasing only for a single taxon, the sevengill shark (Notorynchus cepedianus). Catches of larger, potentially dangerous white sharks (Carcharodon carcharias) and tiger sharks (Galeocerdo cuvier) saw fewer large animals being caught over time. This pattern was not observed across other taxa. Four different monthly trends were observed in landings of the most abundant eight taxa, reflecting differences in the biology of the catch species. The current study also provides useful information on catches and sizes of grey nurse (Carcharias taurus) and white sharks before and after their protection in NSW waters in 1984 and 1998, respectively.

Catch Rates

A joint program between New South Wales Fisheries and three fishing clubs was initiated in 1988 with the aim of collecting standardised catch and effort data during biannual fishing competitions on three major rivers in New South Wales. This paper examines the data to determine trends in the catch of the target species, Australian bass (Macquaria novemaculeata) and to evaluate whether the data can be used to assess Australian bass populations over time. Distinct trends in Australian bass mean length in each river system were evident but catch rates were more variable. Median catch per unit effort was similar (mostly between 0.5 and 1.5 Australian bass·h-1 ) in the Nepean and Williams Rivers although catch rates in the Manning River were nearly always zero. There was an increasing trend in the mean length of Australian bass in all three rivers, possibly representing a recovery in fish populations following severe drought from 1979 to 1983. Low or zero catch rates were continually recorded in the Manning River and size composition data indicated a lack of recruitment through most of the study period. The standardised format of the data collection program provided qualitative and reliable time series data allowing the determination of long-term trends in the population structure of Australian bass which can be used for monitoring and management purposes.

Species Groups

Two strikingly different kinds of Stenoperla larvae are recorded from Australia. For this reason, and others, a subdivision of Australian Stenoperla into two species-groups (australis group, kuna group) is proposed. The following taxa are recognized within Australian Stenoperla: S. australis Tillyard, now known from south-eastern Queensland and north-eastern New South Wales; S. denise, sp. nov., from south-eastern Queensland and eastern New South Wales; S, kuna, sp. nov., from south-eastern New South Wales and Victoria; S. macrops, sp. nov., from the peaks of Mt Bartle Frere and the Bellenden Ker Range in northeastern Queensland; S. wongoonoo, sp. nov., with the typical subspecies in south-eastern Queensland and north-eastern New South Wales, and S. wongoonoo tropica, subsp. nov., in north-eastern Queensland. S. australis is redescribed from fresh material, the new taxa are described; all forms are figured. A key is presented for the identification of all known Stenoperla in Australia (adults and larvae).

Catch Rates

Upper continental slope trawling grounds (200–650 m depth) off New South Wales were surveyed with the same vessel and trawl gear and similar sampling protocols in 1976–77 (during the early years of commercial exploitation) and in 1996–97. The 1996–97 mean catch rate of sharks and rays, pooled for the main 15 species (or species groups), was ~20% of the 1976–77 mean. Individual catch rates were substantially lower in 1996–97 for 13 of the 15 species or species groups. The greatest decline was observed for dogsharks of the genus Centrophorus, which were most abundant in 1976–77 but rarely caught 20 years later. In contrast, 1996–97 catch rates of spiky dogshark (Squalus megalops) and, to a lesser extent, whitefin swell shark (Cephaloscyllium sp. A) were similar to those in 1976–77. Trawling during 1979–81 provided data for nine species, albeit not corrected for larger gear size, and the pooled mean catch rate for sharks and rays in the depth range 300–525 m was ~28% of the mean for 1976–77. The results suggest that the biomass of most species of sharks and rays declined rapidly as the fishery developed and is now at very low levels.

The Australian species of the water beetle genus Hydraena Kugelann, 1794, are revised, based on the study of 7,654 specimens. The 29 previously named species are redescribed, and 56 new species are described. The species are placed in 24 species groups. High resolution digital images of all primary types are presented (online version in color), and geographic distributions are mapped. Male genitalia, representative female terminal abdominal segments and representative spermathecae are illustrated. Australian Hydraena are typically found in sandy/gravelly stream margins, often in association with streamside litter; some species are primarily pond dwelling, a few species are humicolous, and one species may be subterranean. The areas of endemicity and species richness coincide quite closely with the Bassian, Torresian, and Timorian biogeographic subregions. Eleven species are shared between the Bassian and Torresian subregions, and twelve are shared between the Torresian and Timorian subregions. Only one species, H. impercepta Zwick, is known to be found in both Australia and Papua New Guinea. One Australian species, H. ambiflagellata, is also known from New Zealand.
