Genetic data were collected from eight allopatric populations of the common freshwater catfish, Tandanus tandanus. Catfish sampled from the New South Wales (NSW) mid-northern coastal rivers of the Bellinger, Macleay, Hastings and Manning exhibited fixed allelic differences from T. tandanus from the type locality (Namoi River) at four enzymatic loci (GPI-1*, EST*, UMB-1* and UMB-2*), suggesting that, collectively, catfish from these four river systems constitute an undescribed species of Tandanus. Catfish from the northern coastal rivers of NSW (Tweed, Richmond and Clarence) displayed a complex pattern of population structure that was not fully resolved by the present study. More work is needed on the complex assemblage of populations of eel-tailed catfish in the eastern coastal drainages of Australia.

A fore-knowledge of the wind and weather is an object so very interesting to all classes of men, and the changes in the mercurial barometer affording the means which appear most conducive to it, a system that should with certainty explain the connection between the variations of the mercury and those in the atmosphere under all circumstances, becomes greatly desirable; to seamen, more especially, whose safety and success depend so much upon being duly prepared for changes of wind, and the approaching storm, it would be an acquisition of the first importance: in a more extended view, I may say, that the patriot and the philanthropist must join with the philosopher and the mariner in desiring its comple­tion. So long and widely-extended a course of observation, however, seems requisite to form even a basis for it, that a complete system is rather the object of anxious hope than of reasonable expectation. Much has been done towards it, but so much appears to remain, that any addition to the common stock, however small, or though devoid of philosophical accuracy, I have thought would be received by the learned with candour. With this prepossession, I venture to submit to them some observations upon the movement and state of the mercury upon the coasts of New Holland and New South Wales, the Terra Australis, or Australia, of the earlier charts.

Natural Barrier

The fish fauna of all major streams within the Lake Eucumbene catchment in south-eastern New South Wales was sampled by electrofishing or poisoning with rotenone. Galaxias coxii was found in only four, and G. olidus in only one other of the 27 streams sampled whereas the introduced salmonids (Salmo trutta or S. gairdneri, or both) occurred in all but the stream containing G. olidus. Values for galaxiid biomass were low in comparison with those for trout where both occurred together. Sampling in 1971 and 1974 in the one stream observed in 1971 to contain only G. olidus spanned an invasion by S. gairdneri and by 1974 the galaxiid species had completely disappeared below a natural barrier to trout, but above this barrier the biomass and population structure of G. olidus had not changed greatly compared to the 1971 values. This indicated that the presence of S. gairdneri was the sole environmental factor causing galaxiid disappearance below the barrier. Historical data for the catchment area suggested that the introduction and subsequent success of trout are primarily responsible for the present, much fragmented galaxiid distribution.

A New Species

The stiletto fly subfamily Agapophytinae is diverse and species rich in Australasia, with numerous undescribed species. A new species of Acraspisoides Hill & Winterton, A. monticola sp. nov., is described from females collected in montane localities in eastern Australia. Eight new species of Bonjeania Irwin & Lyneborg are also described, raising the total number of known species to 18. Five new species, B. affinis sp. nov., B. apluda sp. nov., B. bapsis sp. nov., B. webbi sp. nov. and B. zwicki sp. nov., all have a distinctive, forward-protruding head with antennae on a raised tubercle. Two other new species, B. argentea sp. nov. and B. jefferiesi sp. nov., are closely related to B. segnis (White), with very similar shaped male genitalia and body shape. An eighth species, B. lambkinae sp. nov., is closely related to B. clamosis Winterton & Skevington. Bonjeania and Acraspisoides are diagnosed and revised keys to species presented. An unusual new therevid, Vomerina humbug gen. et sp. nov., is also described and figured based on a series of males from New South Wales. This new genus likely represents the sister taxon to Bonjeania.

Geographic Distributions

Surveys of Scelio spp., parasites of acridid eggs, were conducted in southern Australia during 1990-94. Parasitism of economically important grasshopper and locust species was frequently substantial confirming an important, albeit often localised, role by Scelio spp. in regulating host populations. Parasitism of Phaulacridium vittatum eggpods in tableland districts averaged 33.5% +/- s.d. 9.5 (range 27.4-47.1) and Chortoicetes terminifera throughout southern Australia averaged 19.8% +/- s.d. 24.6 (range 0-78.9). Scelio spp. were stenophagous and although some species parasitised several hosts, typically a principal host was readily identifiable. Scelio parvicornis was an exception in having two equally important hosts (P. vittatum and C. terminifera) and several subordinate alternative hosts (Oedaleus australis, Brachyexarna lobipennis and A. vulgaris). New hosts were recorded for S. fulgidus (Gastrimargus musicus), S. chortoicetes (Austroicetes vulgaris), S. parvicornis (Brachyexarna lobipennis, P. vittatum and A. vulgaris), S. flavicornis (C. terminifera), S. sp. nr flavicornis (Praxibulus insolens), S. ignobilis (Aiolopus thalassinus tamulus), S. bipartitus (C. terminifera) and S. orientalis (P. insolens). Significant new geographic distributions include S. parvicornis, S. fulgidus, S. sp. nr improcerus and S. flavicornis from Western Australia and S. orientalis and S. ignobilis from New South Wales. Undescribed species were reared from 29 pods of C. terminifera, P. vittatum, Macrotona australis and P. insolens.

Habitat loss and fragmentation are key threats to local koala (Phascolarctos cinereus) populations. Broad-scale management is suboptimal for koalas because distribution models are not easily generalised across regions. Therefore, it is imperative that data relevant to local management bodies are available. Genetic data provides important information on gene flow and potential habitat barriers, including anthropogenic disturbances. Little genetic data are available for nationally significant koala populations in north-eastern New South Wales, despite reported declines due to urbanisation and habitat loss. In this study, we develop 14 novel microsatellite loci to investigate koala populations in north-eastern New South Wales (Port Macquarie, Coffs Harbour, Tyagarah, Ballina) and south-eastern Queensland (Coomera). All locations were significantly differentiated (FST = 0.096–0.213; FʹST = 0.282–0.582), and this pattern was not consistent with isolation by distance (R2 = 0.228, P = 0.058). Population assignment clustered the more northern populations (Ballina, Tyagarah and Coomera), suggesting contemporary gene flow among these sites. For all locations, low molecular variation among (16%) rather than within (84%) sites suggests historical connectivity. These results suggest that koala populations in north-eastern New South Wales and south-eastern Queensland are experiencing contemporary impediments to gene flow, and highlight the importance of maintaining habitat connectivity across this region.

AbstractAllozyme electrophoresis was used to examine the stock structure of arrow squid Nototodarus gouldi (McCoy 1888) from Australia. Samples collected from six localities around southern Australia, separated by distances of between 700 and 4300 km, were examined for allozyme variation at 48 loci. The data revealed no evidence of more than a single species among the 203 squid examined. Nine polymorphic loci were detected, although only three were sufficiently variable to provide real insight into the population structure of arrow squid. There were no significant deviations from Hardy–Weinberg expectations for any locus, population, or for the metapopulation. Pairwise comparisons of allele frequencies revealed minor evidence of stock structure, with the Iluka (north New South Wales) sample set displaying significant allelic differences from the Tasmanian sample set at Acyc and from the Ulladulla (south New South Wales) sample set at Sordh. F-statistics also provided weak support that the Australian metapopulation is not panmictic. Further studies are needed to delineate the degree of stock segregation within the Australian/New Zealand region in order to successfully manage the arrow squid fishery in these waters.

Comprehensive Framework

This paper focuses on teacher attitudes to educational provisions for gifted and talented children in two countries. A questionnaire was distributed to 100 teachers in Sydney, New South Wales and to 100 teachers in Essex, England. Both groups represented a range of primary and secondary schools. Teachers had between 5 and 20 years experience and most were aged between 30 and 40 years. The common factor was acceptance of provisions within the comprehensive framework of education but rejection of any provisions that might be interpreted as elitist. It was also considered that there should be pre-service and in-service training in teaching methods for gifted education for all teachers so that the individual talents of children can be accommodated according to their needs within the comprehensive system.
