The Platypezidae of the Oriental and Australasian Regions are revised, on the basis of a study of surviving types and other available material from these Regions. All genera and species are keyed and described; male genitalia and other diagnostic features are figured, and possible relationships are discussed. Seven genera with 43 species are recognised (19 in 7 genera are Oriental, 25 in 3 genera are Australasian, 19 in Australia itself; one species, Lindneromyia argyrogyna (de Meijere), in both Regions), 24 of them described as new: Microsania boycei (Vic, NSW), M. arthuri (Tas, NSW, WA, PNG), M. nigralula (Qld, WA, PNG), M. unicornuta (PNG), M. hebridensis (Vanuatu), M. albani (Philippines), M. lanka (Sri Lanka), Agathomyia austrocollinella (NSW), A. pluvialis (PNG), Platypeza burmensis (Burma), P. malaisei (Burma), Lindneromyia gressitti (New Britain, PNG, Larat, Qld, NSW), L. curta (Indonesia, Vietnam, India, Sri Lanka), L. kandyi (Hong Kong, Singapore, Vietnam, Sri Lanka), L. quatei (Vietnam), L. pendleburyi (Malaysia, Indonesia, Vietnam, Philippines), L. waui (PNG), L. fonsecai (NSW), L. argentifascia (NSW, ACT, Qld), L. austraquila (ACT, NSW, Qld), L. flavipalpis (Vic, NSW, SA, WA), L. albomaculata (NSW), L. pulchra (Qld, NSW) and L. merimbulae (NSW). An enlarged concept of Lindneromyia Kessel, anticipated in recent Catalogues, is discussed and justified; L. sauteri (Oldenberg), L. kerteszi (Oldenberg) and L. bnmettii (Kessel & Clopton) are new combinations. The following new synonymies are established: Agathomyia antennata (Zetterstedt) = A. hardyi Kessel & Clopton, Lindneromyia bmnettii (Kessel & Clopton) = Plesioclythia schlingeri Kessel & Clopton. Lectotypes are designated for Agathomyia thoracica Oldenberg, Clythia sauteri Oldenberg, C. kerteszi Oldenberg, Platypeza glaucescens Walker and P. obscura Brunetti.

Der volle Inhalt der QuelleAnnotation:
The distribution of tailor (Pomatomus saltatrix) larvae is described on the basis of the results of four plankton surveys undertaken in northern and central New South Wales (NSW) coastal waters. These comprised a single survey during May 1989 along the northern NSW coast and multiple surveys in January, March and May 1983 between Sydney and Brisbane. Pomatomus saltatrix larvae occurred throughout the survey period, with the highest abundances on the northern NSW coast. Most larvae were caught in mid and outer continental shelf waters at water temperatures of ≥22�C. The only known spawning locality for P. saltatrix is in the vicinity of Fraser Island in southern Queensland from August to October. The occurrence of larvae along the NSW coast from January to May indicates that the spawning season of P. saltatrix is more extensive than previously reported and that spawning occurs along the east coast of Australia in localities other than Fraser Island. Further surveys of larvae in southern Queensland and northern NSW waters, especially from August to December, are required to determine if P. saltatrix has one extended or two discrete spawning seasons along the eastern coast of Australia.

Marine and Freshwater Research 60, Nr. 1 (2009): 34. http://dx.doi.org/10.1071/mf08022.
Der volle Inhalt der QuelleAnnotation:
The maintenance of genetic diversity and gene flow in threatened species is a vital consideration for recovery programs. The endangered Oxleyan pygmy perch Nannoperca oxleyana has a fragmented distribution within coastal freshwater drainages of southern Queensland and northern New South Wales, Australia. In the present study, mitochondrial DNA control region variation was used to assess genetic diversity and structure across the geographical range of this species. Haplotypic diversity was highest in a small NSW subcatchment south of Evans Head (h = 0.594) followed by Marcus Creek in Queensland (h = 0.475). Distinct genetic differentiation was evident among the Queensland localities and the NSW subcatchments, implying restricted gene flow between coastal river systems. One of the nine haplotypes detected was distributed over 83.4% of the species’ range, suggesting historical connectivity among the now fragmented populations. These patterns were concordant with eustatic changes associated with the last glacial maximum. High barrier sand dunes may also act as barriers to gene flow and dispersal between adjacent NSW subcatchments. Conservation efforts should focus on the preservation of genetic diversity by maintaining as many genetically differentiated populations as possible. The relatively diverse populations inhabiting the South Evans Head subcatchment and Marcus Creek require special management consideration.

Der volle Inhalt der QuelleAnnotation:
There are few freshwater lakes associated with coastal dunes in southern New South Wales (NSW). Lake Nargal near Narooma, Bondi Lake near Bega, and a small lagoon near Pambula have little in common limnologically with coastal dune lakes of northern NSW and southern Queensland. They differ in mode of origin, are less dominated by NaCl, are less acidic, are more speciose, have few characteristic dune-lake indicator species, and moreover contain certain southern species. However, a re-examination of data for Lakes Windermere and McKenzie further north at Jervis Bay suggest that these are classic dune-contact lakes rather similar to those in northern NSW. Differences and similarities are largely influenced by the extent and therefore the hydrological influence of the contextural coastal sand mass and by biogeography.

Der volle Inhalt der QuelleAnnotation:
Differential survival and recruitment patterns are commonly ignored within plant selection and breeding programs, where attention is focused largely on selection of cultivars with high biomass and seed yields. However, in low-input situations, where fertiliser application is limited, the use of pasture species with superior survival and recruitment characteristics can offer the potential of cost-effective pasture establishment. We investigated the comparative survival and seedling recruitment of 62 native and introduced perennial grasses under low-fertility conditions within three agro-ecological zones of temperate Australia: the temperate high-rainfall pasture zone; drier mixed-farming areas and Mediterranean southern Australia. Plants were grown from seed in glasshouses and transplanted to the field as spaced plants within 6–8 weeks. At regular intervals, survival of transplanted plants and recruitment of new plants were recorded. We found high mortality over a relatively short (24-month) period among both native and introduced grasses, despite good establishment. Frost damage at the cooler sites resulted in death of some C4 plants early in the experiment. Survival of some lines declined following the dry summer of 2000–01, and lines with best survival after this time were Eragrostis curvula cv. Consol, Austrodanthonia fulva (from Dalgety and Wagga, NSW) and Paspalidium jubiflorum (from Warren, NSW). C3 grasses, which generally had poor survival were a Microlaena stipoides selection from Nile, Tasmania, and two lines of Elymus scaber (Boorowa and Tumut, NSW). The C4 grasses Chloris truncata (Girilambone, NSW) and Dichanthium sericeum (Trangie, NSW) also exhibited poor survival, although there were exceptions at some sites. The native lines A. caespitosa Tas2407, M. stipoides cv. Shannon and A. racemosa were the most successful recruiters. Introduced lines generally had lower recruitment, although two lines of D. glomerata from Spain recruited well at some sites. C4 lines generally had poor recruitment, including E. curvula cv. Consol, Bothriochloa macra, Themeda australis, Enteropogon acicularis, D. sericeum, P. jubiflorum and P. constrictum. The role of plants adapted to low-input situations is discussed, as well as the implications of the attributes of survival and recruitment for selection of new cultivars for these situations.

Howickia Richards, 1951, the largest genus of Sphaeroceridae in Australia, is revised to include 43 species, including all wingless Australian species of the family. The following new species are described: H. acicula (TAS), H. auricoma (VIC), H. biantenna (TAS), H. cruspica (VIC), H. erythrocephala (NSW), H. flagella (TAS), H. grandisterna (TAS), H. holti (NSW), H. irwini (NSW), H. loligo (TAS), H. notechis (TAS), H. nuda (NSW), H. pertusa (TAS), H. pinnula (TAS), H. pseudovittata (NSW, QLD), H. robustaseta (NSW), H. tricolor (NSW), H. truemani (TAS), H. wamini (NSW, QLD, TAS, WA), and H. xanthocephala (QLD, NSW). The genera Apterobiroina Papp, 1979, Australimosina Papp, 2008, Bentrovata Richards, 1973, Monteithiana Richards, 1973, Popondetta Richards, 1973, and Otwayia Richards, 1973 are treated as new synonyms of Howickia. Howickia is redefined and placed in the context of a key to genera of Sphaeroceridae in Australia, the Australian species of Howickia are keyed, and a morphological phylogeny is given for the Australian species. The following new combinations are given: Howickia australis (Papp, 1979) comb. nov., Howickia cynthia (Richards, 1973) comb. nov., Howickia dealata (Richards, 1973) comb. nov., Howickia flavipes (Papp, 2021) comb. nov., Howickia flaviterga (Richards, 1973) comb. nov., Howickia flavithorax (Papp, 2021) comb. nov., Howickia regalis (Richards, 1973) comb. nov., Howickia sabina (Richards, 1973) comb. nov., Howickia truncata (Papp, 2021) comb. nov., Paralimosina nasalis (Richards, 1973) comb. nov. (formerly in Pseudocollinella Duda, 1924), Pseudopterogramma fenestrata (Richards, 1973) comb. nov. (originally as Leptocera (Limosina) Macquart, 1835, transferred to Biroina Richards, 1973 by Marshall in Roháček et al. (2001)), and Pleuroseta dorrigonis (Richards, 1973) comb. nov. (formerly in Biroina). A new name, Howickia neoregalis nom. nov. is proposed for H. regalis Marshall, 2014, junior homonym of H. regalis (Richards, 1973). The following genera are newly recorded from Australia: Chaetopodella Duda, 1920, Paralimosina Papp, 1973, Pachytarsella Richards, 1963, Parapterogramma Papp, 2008, Philocoprella Richards, 1929, Piliterga Papp, 2008, Pterogrammoides Papp, 1972, Spelobia Spuler, 1924, and Spinilimosina Roháček, 1983.

Der volle Inhalt der QuelleAnnotation:
THE Hastings River mouse Pseudomys oralis is one of the rarest of the pseudomyines and is patchily distributed across New South Wales (NSW) and Queensland, although it is believed to have been more common in the past (Watts and Aslin 1981). It is currently listed as ‘endangered’ at both State (NSW) and Commonwealth levels and there have only been three ecological studies of the species (Townley 2000; Keating 2000; Meek 2002a). One interesting aspect of Pseudomys ecology is their patchy distribution across the landscape (Watts and Aslin 1981), even where habitat appears unaltered and undisturbed. Historically, P. oralis was believed to be widely dispersed, preferring creek and gully habitats dominated by Cyperaceae and Juncaceae species (Read 1993a; Pyke and Read 2002). New evidence indicates that water courses are not as important as previously believed with animals being trapped across a range of topography and habitat types (Townley 2000; Meek 2002a).

Der volle Inhalt der QuelleAnnotation:
The distribution of heterobranch sea slugs is generally poorly documented at a regional scale. Thus, it is currently difficult to quantify biodiversity, identify endemic and invasive species, and track range shifts at scales relevant to conservation management. For Lord Howe Island, which lies ~600 km east of the New South Wales (NSW) mid-north coast, data from a range of taxa indicate high biodiversity and endemism, but this has not been examined for heterobranch sea slugs. To address this deficit, we collated occurrence data on sea slugs from both private and public sources, including museum records, scientific literature, field guides and citizen science activities. A total of 186 nominal (formally described) species in 82 genera and 31 families were identified from intertidal and subtidal habitats. Of these, two species are endemic to Lord Howe Island, two have not been recorded elsewhere in Australia, and 28 have not been recorded on the mainland coast of NSW. These results support studies of other taxa suggesting that the relative isolation of the island has facilitated the development of diverse and unique assemblages. However, this isolation is moderated by larval transport from surrounding regions, resulting in considerable overlap of the species pool with the mainland coast of NSW and tropical areas to the north.

Der volle Inhalt der QuelleAnnotation:
A symposium on the dingo (Canis lupus dingo) was held in Sydney in May 1999 to discuss issues surrounding the conflicting views of the dingo: seen both as a potentially threatened species, and as a species that needs to be controlled because of its predation on livestock. The Symposium was particularly relevant to New South Wales (NSW) because of consideration being given to place the dingo on the schedule of NSW vulnerable species, under the NSW Threatened Species Conservation Act 1995. The potential for conflict was exacerbated by concurrent legislative changes in NSW (Rural Lands Protection Act 1998) requiring the Crown to control pest animals declared under the Act. Despite the obvious focus on the NSW situation, many of the issues discussed have wider relevance to the management and conservation of dingoes across Australia.

Der volle Inhalt der QuelleAnnotation:
The eastern pygmy possum (Cercartetus nanus) has a wide distribution in New South Wales (NSW), but is infrequently detected in fauna surveys. We collated available information on the distribution, habitat and detection rates for C. nanus in NSW from results of published and unpublished fauna surveys. These data, and those from the National Parks and Wildlife Service and Australian Museum databases, suggest that C. nanus populations are concentrated in south-eastern NSW and are sparsely distributed throughout the rest of the state. Several records extend the distribution of this species further west than currently shown by published distribution maps. Records show differences in habitat types occupied by C. nanus between south-eastern and north-eastern NSW. In south-eastern NSW, C. nanus occupies a range of habitats including heath, woodland and open forest, at a range of altitudes. In north-eastern NSW, C. nanus appears to be associated mainly with rainforest at high altitudes. Of the range of techniques available, nest boxes and Elliott traps positioned against flowering Banksia species are most effective at capturing C. nanus. Given the large survey effort and the small number of surveys detecting >I0 C. nanus, it appears that this species is rare throughout most of NSW. We recommend that C. nanus be considered for listing as a vulnerable species in NSW.

To assess the status of a putative new species of Elaeocarpus L. (Elaeocarpaceae) from north-eastern New South Wales (NSW), with respect to the morphologically similar E. blepharoceras Schltr. from New Guinea, we undertook morphometric analysis of 11 vegetative attributes measured on 11 specimens of the putative new species and eight of E. blepharoceras. Cluster analysis (flexible UPGMA) and ordination (PCC) separates highland specimens of E. blepharoceras from the NSW material plus lowland E. blepharoceras. Furthermore, the ordination shows some separation of the NSW material into Koonyum Range and Nightcap Range groups. Although it is not clearly differentiated from lowland E. blepharoceras on morphometric analysis, description of the NSW material as E. sedentarius D.J.Maynard & Crayn is justified by (1) additional features such as the anther awns (short and sparsely hairy in E. sedentarius and much longer and densely bristly in E. blepharoceras), variation in the number of locules (3(–4) in E. sedentarius and (2–)3 in E. blepharoceras), leaf margin features (short setae terminating veins on leaf margins of E. blepharoceras, lacking in E. sedentarius) and (2) geographic isolation (>2000 km) is likely to prevent gene flow. The distribution, relationships and conservation status of E. sedentarius are discussed.

Forest management policy in New South Wales, Australia, has been dramatically changing during the past two decades in response to public controversy and widening expectations of the values that the forest should provide to society. The nature of NSW forest management today is a reflection of the unique Australian forest ecology, the nature of the forest sector, and the emergence of conflict and polarized views on forest management in the past two decades. Recent efforts have made progress in resolving the forest debate. The key elements have included an expanded protected areas reserve system, expanded reliance on plantation forests for wood supply, increased wood security for native forest industries in return for a commitment to value-adding and the implementation of an ecologically sustainable forest management framework. Like other Australian States, NSW is currently negotiating Regional Forest Agreements with the Commonwealth Government that will set the stage for future directions in forest management. Key words: forest policy, Australia, New South Wales forest management

Der volle Inhalt der QuelleAnnotation:
Yellow-footed rock-wallabies (Petrogale xanthopus) are listed as endangered in New South Wales (NSW). Annual helicopter surveys have been conducted, during winter, on the NSW population since 1980. Correlation analysis suggested that the exponential rate of increase (r) of the population was positively related to rainfall in the previous calender year. Ivlev's inverted exponential numerical response model was found to adequately represent the relationship between r and rainfall, though the fit was poor (R2 = 0.43). Examination of the fit of the numerical response model and the predictions for the consonants used in the model suggested that the lower end of the function was better approximated than the upper end. The predicted values for the maximum rate of decrease and the level of rainfall at which r would became positive could be intuitively explained given aspects of the wallabies' ecology. However, the estimated maximum rate of increase was far below theoretically predicted values, which suggested that the expected positive correlation between rainfall and recruitment was weak. This suggested that the NSW P. xanthopus population was not primarily regulated by absolute resource availability during the period of the study. Possible intrinsic and extrinsic factors that detrimentally influenced the population are proposed.

Lentil, an important pulse crop in Australia, is sown soon after the onset of autumn rains and grows mainly under rainfed conditions. This study examined lentil phenological development, growth and grain yield under different sowing dates and environments in New South Wales (NSW). Eight lentil varieties were phenotyped over two years and four sowing times in southern NSW (Leeton, Wagga Wagga and Yanco (one year)) and central western NSW (Trangie). Time of sowing affected important agronomic traits, with a delay in sowing decreasing time to flowering and podding, biomass accumulation, plant height and position of bottom pod. Sowing earlier or later than optimum decreased grain yield. Yield was mainly determined by the number of pods and seeds per plant, with minimal impact from seed weight. Overall, yields were higher in favorable environments such Leeton experiment which received more water compared to the other sites which received less water. Averaged across sowing dates, the slower maturing PBA Greenfield was lower yielding whilst fast maturing varieties such as PBA Bolt and PBA Blitz yielded higher. PBA Jumbo2 is less sensitive to environmental interaction and thus broadly adapted to the diverse environments. Optimum sowing time was identified as the end of April to mid-May.

Carp (Cyprinus carpio L.) were introduced to Australia on at least three occasions over the past 100 years. These introductions were to the Prospect Reservoir, Sydney (1907), the Murrumbidgee Irrigation Area, New South Wales (NSW) (1940s), and to Boolarra, Victoria (1960). Koi, a colourful variety of carp, have been introduced to several areas as well. Carp are now widely spread throughout south-eastern Australia. This study aimed to investigate genetic variation of carp in south-eastern Australia. Carp from several localities were examined at seven polymorphic allozyme loci and with three restriction enzymes detecting polymorphic sites in mitochondrial DNA. Three composite mtDNA haplotypes were found. Haplotype 1 was spread throughout the study area, occurring in 72% of all individuals examined. Haplotype 2 was localized to south-western NSW and occurred in 4% of individuals. Haplotype 3 was found in the Australian Capital Territory and Tasmania and accounted for 24% of individuals. Little genetic variation within and among carp populations was observed in the mitochondrial DNA data. The allozyme data showed greater variation within populations than did the mitochondrial DNA data.

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.

Der volle Inhalt der QuelleAnnotation:
Whether the eastern quoll (Dasyurus viverrinus) is extinct on mainland Australia, particularly New South Wales (NSW), is the focus of this study. The species declined rapidly during the mid to late 1800s in parts of south-east Australia and in the early 1900s around Bega (New South Wales). The last definite live individual was recorded at Vaucluse, NSW in 1963. The recent emergence of a specimen from Barrington Tops, NSW, in 1989 caused much public interest and enabled us to seek reports of sightings after we advertised publicly for any records. Here we document numerous post-1963 records, the most noteworthy including: a photograph of an eastern quoll (reported to be taken in 2013 in the Nungatta area of NSW), records from Wollemi National Park (2002 and 2006) and multiple observations from the 1990s from around Barrington Tops and Carrai. There has been insufficient recent mammal survey effort to definitively support these public reports but at this stage there are sufficient recent credible records to consider that this species may not be extinct on mainland Australia.

A new species, Eucalyptus deuaensis Boland & Gilmour, is described. Its taxonomic position is in subgenus Monocalyptus, section Renantheria, series Capitellatae, following the informal classification of Pryor and Johnson (1971). The species is somewhat unusual in that it is a gum-barked 'Stringybark', i.e. its fruit and seedling morphology conform with those species normally having their trunks clothed with Stringybark. E. deuaensis is known only from the type locality, near Mongamulla Moun- tain, where the population extends over several hectares on steep rhyolitic cliffs. Analyses of the oil composition of the adult leaves were not definitive for the species, but suggested similarities with other stringbark species. The ecology, distribution, taxonomic affinities and conservation status are discussed.

Der volle Inhalt der QuelleAnnotation:
Hyparrhenia hirta (L.) Stapf (also known as Coolatai grass, South African bluestem or thatching grass) has become a serious invasive weed in Australia. Within its native range, it is generally regarded as a useful grass particularly for thatching, and seed production is low with a low soil seed bank of from 2 to 200seedsm–2. Several hundred accessions of H. hirta were deliberately introduced into Australia up until the 1980s and nearly all were discarded because of poor seed production. However, at least one introduction in the 1890s in northern New South Wales (NSW), Australia, has possibly contributed to the present serious weed problem. Annual seed production from roadside stands in northern NSW ranged from 7000 to 92000seedsm–2 in 2015. The soil seed bank under dense H. hirta infestations in the same region in 2006 and 2007, was found to be ~30000seedsm–2 mostly confined to the top 2cm, with few dormant seeds and a large reduction of these numbers over the next 12 months when further seed input was prevented. Similar studies of other perennial grass weeds have found seed banks of similar sizes, but dormancy mechanisms ensure that their seed banks last for at least 10 years without further seed input. These results suggest that the present weedy populations of H. hirta have dramatically increased fecundity enabling a large seed bank to develop beneath dense stands. The development of seed dormancy and consequently a long-lived seed bank would make this weed even more difficult to control. Until seed dormancy develops, control of H. hirta in northern NSW can be effective provided further input into the seed bank can be prevented.

Der volle Inhalt der QuelleAnnotation:
Delineating stocks and quantifying population structure are critical for the management of exploited populations, but the stock structure of many species remains unclear. In New South Wales (NSW), Australia, a marine stock enhancement program for dusky flathead (Platycephalus fuscus) is developing, and knowledge of stock structure is required to inform enhancement strategies, as well as to support broader fisheries management. A combination of mitochondrial and microsatellite markers was used in this study to evaluate structuring among fish from eight estuaries, spanning the majority of the NSW coast. Pairwise comparisons of mitochondrial haplotypes revealed that seven of the eight estuaries were genetically homogeneous (St Georges Basin was distinct). Moreover, analysis of molecular variance showed that 97% of sequence diversity occurred within estuaries. The results from microsatellite markers were almost identical to those for mitochondrial DNA, with St George’s Basin having the only distinct genotype, and within estuary variation accounting for 99% of the genotype variation. Isolation by distance analysis showed that <5% of genetic variation was due to distance. These results indicate that dusky flathead forms a single stock across NSW, where mixing most likely occurs during early life phases and through limited adult migration. The outlying estuary, St Georges Basin, likely suffers from limited connectivity due to a constricted entrance, and it is possible that stocking may improve local genetic diversity.

Following a morphometric and cladistic analysis of the Daviesia ulicifolia Andrews group (Chandler and Crisp 1997), a new species, D. sejugata, is described. It occurs disjunctly in eastern Tasmania and southern Yorke Peninsula, South Australia, and is closely related to D. arthropoda F.Muell., differing in a generally more robust habit, thicker fleshy phyllodes, and larger flowers. Even with this species removed from D. ulicifolia, the latter varies considerably over a wide geographic, edaphic and altitudinal range. Daviesia ulicifolia is divided into six subspecies based on distinct phenetic and phylogenetic groups delimited in the earlier study. These are subsp. aridicola (glaucous plants in arid regions), subsp. incarnata (reddish-flowered plants in the Mt Lofty Range, South Australia), subsp. ruscifolia (plants with ovate-acuminate leaves and orange flowers in Victoria and southern New South Wales (NSW), often at high altitude), subsp. stenophylla (a narrow-leaved form in northern NSW and Queensland), subsp. pilligensis (ovate-leaved plants on sandy soil in western NSW), and subsp. ulicifolia (a paraphyletic residual from south-eastern states).

In the face of accelerating climate change, conservation strategies will need to consider how marine animals deal with forecast environmental change as well as ongoing threats. We used 10 yr (2009-2018) of data from commercial fisheries and a bather protection program along the coast of New South Wales (NSW), southeastern Australia, to investigate (1) spatial and temporal patterns of occurrence in bull sharks and (2) environmental factors affecting bull shark occurrence along the coast of NSW. Predicted future distribution for this species was modelled for the forecast strengthening East Australian Current. Bull sharks were mostly harvested in small to larger estuaries, with average depth and rainfall responsible for contrasting patterns for each of the fisheries. There was an increase in the occurrence of bull sharks over the last decade, particularly among coastal setline fisheries, associated with seasonal availability of thermal gradients >22°C and both westward and southward coastal currents stronger than 0.15 and 0.60 m s-1, respectively, during the austral summer. Our model predicts a 3 mo increase in the availability of favourable water temperatures along the entire coast of NSW for bull sharks by 2030. This coastline provides a uniquely favourable topography for range expansion in the face of a southerly shift of warmer waters, and habitat is unlikely to be a limiting factor for bull sharks in the future. Such a southerly shift in distribution has implications for the management of bull sharks both in commercial fisheries and for mitigation of shark-human interactions.

Der volle Inhalt der QuelleAnnotation:
An assessment of the relative influences of management and environment on the composition of floodplain grasslands of north-western New South Wales was made using a regional vegetation survey sampling a range of land tenures (e.g. private property, travelling stock routes and nature reserves). A total of 364 taxa belonging to 55 different plant families was recorded. Partitioning of variance with redundancy analysis determined that environmental variables accounted for a greater proportion (61.3%) of the explained variance in species composition than disturbance-related variables (37.6%). Soil type (and fertility), sampling time and rainfall had a strong influence on species composition and there were also east–west variations in composition across the region. Of the disturbance-related variables, cultivation, stocking rate and flooding frequency were all influential. Total, native, forb, shrub and subshrub richness were positively correlated with increasing time since cultivation. Flood frequency was positively correlated with graminoid species richness and was negatively correlated with total and forb species richness. Site species richness was also influenced by environmental variables (e.g. soil type and rainfall). Despite the resilience of these grasslands, some forms of severe disturbance (e.g. several years of cultivation) can result in removal of some dominant perennial grasses (e.g. Astrebla spp.) and an increase in disturbance specialists. A simple heuristic transitional model is proposed that has conceptual thresholds for plant biodiversity status. This knowledge representation may be used to assist in the management of these grasslands by defining four broad levels of community richness and the drivers that change this status.

Der volle Inhalt der QuelleAnnotation:
Brush-tailed Rock-wallabies Petrogale penicillata are still widely distributed in the gorges on the east of the New England Tablelands of northern NSW, in small (mean <6 adults) colonies, separated by an appreciable distance (median separation 308 m) from neighbouring colonies. Within colonies, established adults occupy a refuge or set of refuges by day, moving away from the colony to forage mainly at night. A set of 1-3 adult females shares a small number of refuges, with one adult male defending access to them and their refuges. A colony contains one or several such sets. Established females occupy refuges persistently, up to at least 4 years and perhaps until death; males also defend their diurnal ranges persistently, but male ranges do change owner through intrusion or supplanting, as well as when the incumbent dies. Sub-adults of both sexes seem to be the dispersing classes, although a daughter may remain, mature and breed in her mother’s range. Only adults established in refuges appear to breed. The most dominant among the females sharing a set of refuges tends to produce more young than do subordinates. The combination of small and separated colonies, dispersal only by naive sub-adults, a strong restriction of mating opportunities within breeding groups, and unequal contribution to breeding even by females, could make P. penicillata prone to predation by agile predators that can learn the locations of their persistently used sites, and to problems of conserving population numbers and allelic diversity. These latter conservation problems can be simply addressed by artificial dispersal (translocation) of appropriate animals.

In 1996, guidelines were produced for capture and radio-tracking protocols for koala (Phascolarctos cinereus) research within New South Wales (NSW). An integrated project commenced in 1998 to examine P. cinereus ecology and health status in Pine Creek State Forest. This project utilised intensive clinical and pathological assessment protocols on captured P. cinereus in combination with radio-tracking and ecological investigations. The methods used in this project were referred to the NSW Koala Research Committee (KRC) for review in mid 1999 due to the political profile of the study area. The KRC assessed the project protocols and reviewed the original guidelines incorporating some of the protocols used in the Pine Creek project. The outcome is a new set of protocols for P. cinereus research within NSW which are more explicit and restrictive than those applied to P. cinereus research elsewhere or to research on other species. In their current form the new guidelines require a substantial investment in time, equipment, personnel and finance; factors that may deter or restrict future, comprehensive ecological research on P. cinereus populations. They inadequately provide for some practices we believe important in minimising the invasiveness of P. cinereus capture. We propose amendments to the guidelines in the areas of personnel required, behavioural assessment, capture methods, processing safety and tracking frequency. We suggest that these amendments will render the guidelines more accessible to a broader range of projects, and easier to apply under field conditions while preserving the intent to maintain P. cinereus welfare and research best practice.

A bacterial strain, designated NSW-5T, was isolated from a water sample taken from Niao-Song Wetland Park in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain NSW-5T were strictly aerobic, Gram-stain-negative, non-motile and polymorphic, being straight, vibrioid, curved and spiral-shaped rods surrounded by a thick capsule and forming light pink-coloured colonies. Some rings consisting of several cells were present. Growth occurred at 10–40 °C (optimum, 25 °C), with 0–3.0 % NaCl (optimum, 0 %) and at pH 6.0–8.0 (optimum, pH 7.0). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain NSW-5T belonged to the genus Arcicella with sequence similarities of 98.6, 98.0 and 97.3 % with Arcicella aquatica NO-502T, Arcicella rosea TW5T and Arcicella aurantiaca TNR-18T, respectively. The predominant cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 20.8 %), C16 : 0 (14.6 %), iso-C15 : 0 (13.8 %), C16 : 1ω5c (12.5 %) and C18 : 0 (11.4 %), and the only respiratory quinone was MK-7. The polar lipid profile consisted of phosphatidylethanolamine and several uncharacterized glycolipids, aminolipids, phospholipids and aminophospholipids. The DNA G+C content of strain NSW-5T was 44.1 mol%. The DNA–DNA relatedness of strain NSW-5T with respect to recognized species of the genus Arcicella was less than 70 %. On the basis of phylogenetic inference and phenotypic data, strain NSW-5T should be classified as a representative of a novel species, for which the name Arcicella rigui sp. nov. is proposed. The type strain is NSW-5T ( = KCTC 23307T = BCRC 80260T). Emended descriptions of the genus Arcicella and of Arcicella aquatica , Arcicella rosea and Arcicella aurantiaca are also proposed.

The genus Smeagol consists of five named species of air-breathing marine slugs (restricted to southern Australia and New Zealand) and three undescribed taxa from southern Japan. Only one species, S. hilaris, is known to be from New South Wales (NSW), and it previously had a known distribution limited to one site, Merry Beach on the south coast. This diminutive invertebrate is classified as critically endangered in NSW due to its extremely restricted distribution and concern about its historically declining numbers. Accordingly, the aims of this study were to survey the known population of S. hilaris at Merry Beach and to explore other potentially suitable sites, using a visual census method, to determine if further populations or species exist in NSW. The resulting quantitative surveys of the known population and a new population at Storm Bay, Kiama, NSW, are reported here. DNA barcoding of a ~650 bp segment of the mitochondrial cytochrome c oxidase I (COI) gene for several individuals from each population confirmed the conspecificity among the two populations. The population at Merry Beach was found to remain viable, while the discovery of the new population of S. hilaris represents a doubling of the known global populations of this species. Details of the highly-specialised niche habitat occupied by Smeagol in New South Wales and recommendations for ongoing management are documented.

Surveys of arboreal and terrestrial mammals were conducted across four State Forests in south-east New South Wales encompassing 80 000 ha. Methods used included spotlighting, Elliott trapping, pitfall trapping, hair-tubing and predator scat analysis. The survey included a plot-based approach and the targeting of areas containing the potential habitat of endangered species. Seven species of arboreal marsupial were detected during spotlighting. The greater glider (Petauroides volans) was significantly more abundant in moist forest compared to dry forest. Its density in moist forest was twice as high in unlogged compared to logged forest and is equivalent to the highest recorded in any forest in NSW. Other arboreal species were less abundant. The yellow-bellied glider (Petaurus australis), which is Threatened in NSW, was detected at only two sites despite the occurrence of suitable habitat throughout the study area. Eight species of native terrestrial mammals were detected. The tiger quoll (Dasyurus maculatus), which is Threatened in NSW, appears to be more common in the southern part of the study area adjoining large areas of National Park, than in other State Forests of south-east NSW. Continued analysis of predator scats is required to determine whether several other species of Threatened terrestrial mammal occur in these forests.

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.

Ecological information about threatened species is required to guide strategic management approaches for effective biodiversity conservation in Australia. Arthraxon hispidus (hairy jointgrass) is a listed threatened species in New South Wales (NSW), but there is limited information on its habitat preferences and native vegetation associations, as well as the impact of historical and ongoing anthropogenic disturbance on its distribution and abundance. In the present study, populations of A. hispidus on the north coast of NSW were surveyed to investigate the habitat characteristics associated with various occurrences of the species. Its preferred habitat was found to be dense ground-cover formations in high-moisture, low-canopy conditions. Cover was highest in moisture-associated assemblages in and around wetlands, drainage lines and groundwater seepages, often in association with native grasses, sedges and herbs. These findings suggest that naturally open freshwater wetland communities comprise the most plausible native habitat niches for A. hispidus populations on the north coast of NSW. A. hispidus also occurs widely among introduced pastures and weeds in previously forested areas, demonstrating the species’ potential to exploit derived habitat. Results indicate that, although ongoing disturbance continues to promote A. hispidus in these exotic-dominated landscapes where historical clearing has created potential habitat opportunities, anthropogenic disturbance (slashing or cattle grazing) is not necessary to sustain A. hispidus within native-dominated wetland communities. Findings suggest more scope for integrated management of A. hispidus within broader native vegetation conservation strategies rather than a single species approach.

THE grey-headed flying fox Pteropus poliocephalus is managed simultaneously under two contrasting paradigms in New South Wales (NSW), as a threatened species and as a pest in orchards and at camps in some urban centres. Many authors have called attention to the lack of understanding of the species and the obstacle this may pose for conservation efforts. Managing the grey-headed flying-fox as a threatened species in NSW was produced as a result of a forum held on the 28th of July 2001 by the Royal Zoological Society of New South Wales.

The six species of mountain frogs (Philoria: Limnodynastidae: Anura) are endemic to south-eastern Australia. Five species occur in headwater systems in mountainous north-eastern New South Wales (NSW) and south-eastern Queensland (Qld), centred on the Gondwana Rainforests of Australia World Heritage Area. A previous molecular genetic analysis identified divergent genetic lineages in the central and western McPherson Ranges region of Qld and NSW, but sampling was inadequate to test the species status of these lineages. With more comprehensive geographic sampling and examination of the nuclear genome using SNP analysis, we show that an undescribed species, P. knowlesi sp. nov., occurs in the central and western McPherson Ranges (Levers Plateau and Mount Barney complex). The new species is not phylogenetically closely related to P. loveridgei in the nuclear data but is related to one of two divergent lineages within P. loveridgei in the mtDNA data. We postulate that the discordance between the nuclear and mtDNA outcomes is due to ancient introgression of the mtDNA genome from P. loveridgei into the new species. Male advertisement calls and multivariate morphological analyses do not reliably distinguish P. knowlesi sp. nov. from any of the Philoria species in northeast NSW and southeast Qld. The genetic comparisons also enable us to define further the distributions of P. loveridgei and P. kundagungan. Samples from the Lamington Plateau, Springbrook Plateau, Wollumbin (Mt Warning National Park), and the Nightcap Range, are all P. loveridgei, and its distribution is now defined as the eastern McPherson Ranges and Tweed caldera. Philoria kundagungan is distributed from the Mistake Mountains in south-eastern Qld to the Tooloom Scrub on the Koreelah Range, southwest of Woodenbong, in NSW, with two subpopulations identified by SNP analysis. We therefore assessed the IUCN threat category of P. loveridgei and P. kundagungan and undertook new assessments for each of its two subpopulations and for the new taxon P. knowlesi sp. nov., using IUCN Red List criteria. Philoria loveridgei, P. kundagungan (entire range and northern subpopulation separately) and P. knowlesi sp. nov. each meet criteria for “Endangered” (EN B2(a)(b)[i, iii]). The southern subpopulation of P. kundagungan, in the Koreelah Range, meets criteria for “Critically Endangered” (CE B2(a)(b)[i, iii]). These taxa are all highly threatened due to the small number of known locations, the restricted nature of their breeding habitat, and direct and indirect threats from climate change, and the potential impact of the amphibian disease chytridiomycosis. Feral pigs are an emerging threat, with significant impacts now observed in Philoria breeding habitat in the Mistake Mountains.

Growth to 38 months and severity of Mycosphaerella leaf disease and target spot (caused by Aulographina eucalypti (Cooke & Mass.) von Arx & Muller) were assessed in a Eucalyptus pilularis Smith (blackbutt) family trial in New South Wales (NSW), Australia. Significant variation in growth, disease, and defoliation was found among the 40 provenances and 321 families tested; however, relatively few provenances had concentrations of superior or poor families. Most families in three higher altitude NSW provenances were superior for volume increment, while three southeast Queensland provenances had low mean volume increment. Mycosphaerella damage and defoliation tended to be low in several higher altitude northern NSW provenances, but the southeast Queensland provenances had significantly higher mean defoliation. Individual narrow sense heritability estimates were low to moderate for Mycosphaerella damage (0.38) and defoliation (0.22) and low for Aulographina damage (0.13) and volume increment (0.13). Significant genetic and phenotypic correlations between Mycosphaerella damage and defoliation were low and positive. Low to moderate negative correlations occurred between Mycosphaerella damage and volume increment and between defoliation and volume increment, suggesting that Mycosphaerella leaf disease, in particular, and defoliation had deleterious effects on tree growth. However, the impact of these foliar pathogens on the volume of E. pilularis is often low, so selecting for growth and form alone in the early stages of domestication could provide acceptable gains in yield.

The green macroalga Caulerpa filiformis is rapidly dominating algal assemblages in shallow subtidal regions along the New South Wales (NSW) coast. Given that invasive species are known for their competitive superiority, the interactions between C. filiformis and herbivores and fouling species was investigated and were compared with those co-occurring native species. Extensive field surveys were carried out to assess purported damage from herbivores, and co-occurrence of C. filiformis with herbivorous fish and invertebrate species. Signs of herbivory on C. filiformis were visible, and several common herbivorous invertebrates and fish co-occurred with the alga. Laboratory and field feeding assays with fresh algae indicated that generalist invertebrate herbivores such as Turbo torquatus did not consume C. filiformis, whereas herbivorous fish did consume C. filiformis but not in preference to other palatable algae. C. filiformis was fouled at similar concentrations and with similar epiphytic species to other co-occurring algae. Thus the ability of C. filiformis to deter herbivory and fouling by using biotic deterrents (both chemical and structural) is limited and unlikely to be the major factor driving its successful invasion into NSW habitats.

The diversity in yearly calendars on sheep properties in western NSW is explored using three criteria of analysis which elucidate these calendars: by seasonal perspective, by main operational activity and individual reasons. From a seasonal perspective the 18 articulated systems could be grouped into seven different calendars. The complexity of a grazing system cannot be analysed from a seasonal perspective alone and the main operational activity and reasons given by individual graziers are a means of identifying differences between yearly calendars. A 'decision making' diagram is established combining main operating activity, reasons for planning certain activities and the month(s) in which they are undertaken. The research reported is based on a constructivist epistemology, which acknowledges the existence of multiple valid realities related to human diversity and local knowledge. The results suggest more insight into the motivations, interpretations and understandings of individual graziers can be gained by using methods like open invitations and semi structured interviews to work towards coresearching activities. Valuing human diversity in interpreting, understanding and preference in property management is a step towards managing the semi-arid rangelands of western New South Wales in a ecologically and socially sustainable way.

A bacterial strain, designated Nsw-4T, was isolated from a water sample of Niao-Song Wetland Park in Taiwan and was characterized by using a polyphasic taxonomic approach. Strain Nsw-4T was Gram-negative, aerobic, ivory-coloured, rod-shaped and motile by means of a polar flagellum. Growth occurred at 15–37 °C, pH 6.0–8.0 and 0–2 % NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that the strain belonged to the genus Deefgea and that its closest neighbour was Deefgea rivuli WB 3.4-79T (96.9 %). The results of physiological and biochemical tests allowed the clear phenotypic differentiation of this isolate from D. rivuli WB 3.4-79T. The major fatty acids were C16 : 1ω7c and C16 : 0. The G+C content of the genomic DNA was 53.7 mol%. On the basis of 16S rRNA gene sequence analysis and the chemotaxonomic and physiological data, strain Nsw-4T should be classified as representing a novel species and the second member of the genus Deefgea, for which the name Deefgea chitinilytica sp. nov. is proposed. The type strain is Nsw-4T (=BCRC 17934T=LMG 24817T).

Der volle Inhalt der QuelleAnnotation:
Concepts of the distribution of the greater broad-nose bat (Scoteanax rueppellii) have changed significantly as occurrence records have accumulated over the years. Early accounts of the species' distribution suggested that it was restricted to the heavily timbered areas of eastern Australia, and occurred over a wide range of altitudes. However, recent summaries of the distribution of the species differ significantly from these early accounts. To reconcile these discrepancies, I collated records from museum collections and wildlife databases. These data clearly indicate that stated altitudinal limits for the species are not correct. The currently known southern limit of the species is near Eden, New South Wales (NSW). The distribution of the species was modelled using the DOMAIN climate matching algorithm. The model indicates that S. rueppellii may occur in East Gippsland, Victoria, suggests its likely occurrence in inland Queensland and northern NSW, but a low likelihood of occurrence in inland southern NSW. However, the data show strong spatial and temporal biases that restrict the confidence that may be placed in the model. It is argued that species distributions must be regarded as open and evolving hypotheses.

The remnant New South Wales (NSW) yellow-footed rock-wallaby (Petrogale xanthopus) population underwent a substantial decline between 1985 and 1992 and remained at dangerously low levels until 1995. To determine the processes underlying this decline, a population study was conducted at one colony, between winter 1995 and winter 1998. The colony was observed to remain relatively constant in size, consisting of between 12 or 13 individuals throughout the study. Reproductive rates were found to be relatively high. Both reproduction and pouch young survival were comparable with those reported for other P. xanthopus colonies, while adult survival rates were higher than those noted in other studies. Because population size remained constant during the study and adult survivorship was consistently high, this suggested that juvenile recruitment into the colony was low. Such low levels of recruitment may have had a substantive role in the slow decline of the entire NSW P. xanthopus population. The results of this study suggest that any management actions undertaken in the NSW P. xanthopus population should focus on increasing juvenile survival rates. Further research is required to determine whether juvenile survival is constrained by predation or competition with other herbivores.
