Effective management of sediment fluxes in aquatic systems involves, in part, the identification of catchment sediment sources. Lake Wivenhoe (LW), the largest water storage in south-east Queensland, serves two important roles: it supplies 80% of the drinking water to the region and acts as a major flood mitigation feature for the city of Brisbane. Highly developed subcatchments in LW have resulted in declining waterway health, with sediment movement from the catchment to LW of major concern. Although there is considerable hydrological information, only limited data exist on sediment and nutrient fluxes. A detailed lake sediment (128 samples) and reconnaissance catchment soil sampling program (89 samples) was undertaken. Geochemical, Nd–Sr isotopic and statistical analyses were used to identify major sources of sediment to LW. A purpose-built Bayesian mixing model was then used to quantitatively estimate the proportion of sediment from major catchment sources. Approximately 36% of the LW catchment delivers the majority of sediment; enrichment factors for the three major sediment sources (dam to catchment ratio) range from ~2 to 5. The Esk Formation is the major sediment source comprising ~10% of catchment area but contributing 50% of the sediment and 33% of the total phosphorus delivered to LW.

The Great Sandy Region (incorporating Fraser Island and the Cooloola sand-mass), south-east Queensland, contains a significant area of Ramsar-listed coastal wetlands, including the globally important patterned fen complexes. These mires form an elaborate network of pools surrounded by vegetated peat ridges and are the only known subtropical, Southern Hemisphere examples, with wetlands of this type typically located in high northern latitudes. Sedimentological, palynological and charcoal analysis from the Wathumba and Moon Point complexes on Fraser Island indicate two periods of swamp formation (that may contain patterned fens), one commencing at 12 000 years ago (Moon Point) and the other ~4300 years ago (Wathumba). Wetland formation and development is thought to be related to a combination of biological and hydrological processes with the dominant peat-forming rush, Empodisma minus, being an important component of both patterned and non-patterned mires within the region. In contrast to Northern Hemisphere paludifying systems, the patterning appears to initiate at the start of wetland development or as part of an infilling process. The wetlands dominated by E. minus are highly resilient to disturbance, particularly burning and sea level alterations, and appear to form important refuge areas for amphibians, fish and birds (both non-migratory and migratory) over thousands of years.

Der volle Inhalt der QuelleAnnotation:
The crustacean order Bathynellacea is amongst the most diverse and widespread groups of subterranean aquatic fauna (stygofauna) in Australia. Interest in the diversity and biogeography of Australian Bathynellacea has grown markedly in recent years. However, relatively little information relating to this group has emerged from Queensland. The aim of this study was to investigate bathynellacean diversity and phylogeny in south-east Queensland. Relationships between the south-east Queensland fauna and their continental relatives were evaluated through the analysis of combined mitochondrial and nuclear DNA sequence data. Bathynellaceans were collected from alluvial groundwater systems in three catchments in south-east Queensland. This study revealed a diverse bathynellacean fauna with complex evolutionary relationships to related fauna elsewhere in Queensland, and on the wider Australian continent. The multifamily assemblage revealed here is likely to represent several new species, and at least one new genus within the Parabathynellidae. These taxa likely have relatively restricted geographic distributions. Interestingly, the south-east Queensland Bathynellacea appeared to be distantly related to their north-east Queensland counterparts. Although it was not possible to determine the generic identities of their closest relatives, the south-east Queensland Parabathynellidae appear to be most closely affiliated with southern and eastern Australian lineages. Together with previous survey data, the findings here suggest that there is likely to be considerable bathynellacean diversity in alluvial groundwater systems across the wider Queensland region. Further assessment of stygofauna distributions in south-east Queensland is necessary to understand the biological implications of significant groundwater use and development in the region.

The waterways of South East Queensland, Australia, represent unique and complex ecosystems that have a high conservation value and support major recreational and commercial fisheries. The agricultural districts of the region also contribute significantly to the regional economy and, together with the growing urban areas, are heavily reliant on good quality water supplies. However, the human footprint of these activities has led to significant changes in catchment hydrology and sediment delivery, declining water quality and loss of aquatic biodiversity. Predicted population increases in the region are likely to further impact on the ecological and economic health of its waterways and catchments, and there are growing community expectations to reverse the decline in water quality and ecosystem health. In response to these concerns, government, industry and community stakeholders have worked in close cooperation to develop a whole-of-government, whole-of-community approach to understanding and managing the region's waterways. This paper provides an overview of the experience gained through development of the SEQ Healthy Waterways Partnership and highlights some of the key factors we believe have contributed to its success.

Australia is a country comprising the mainland of the Australian continent and the island of Tasmania. The country also includes numerous smaller islands in the Pacific and Indian Ocean. Australia is the sixth-largest country in the world by total area. It also has the world’s 12th-largest economy and fifth-highest per capita income. On 1 January 1901, a federation of six separate British self-governing states was formed after a decade of planning, consultation and voting. This established the Commonwealth of Australia as a dominion of the British Empire. In 1931 the status of the dominions was made equal to that of Great Britain, which is considered the symbolic date of Australia gaining full independence. Before World War II and in the course of it, the Commonwealth of Australia was closely tied to the government in London. However, the fall of the British Empire in the Asia Pacific made Australian authorities rethink their existence in the new reality. In the late 80s, Australia’s formal ties with London were further loosened, as planned. Since that time the role and significance of the continent has been growing. A vibrant economy and favourable location drive the country’s growing importance, which the government in Canberra strongly focuses on. Economic success and effective policies have made Australia become one of the crucial elements of sustainable balance in the South Pacific region. However, the country’s political and economic influence goes far beyond its borders. Australia’s importance to and influence on neighbouring countries is clearly visible across East and Southeast Asia, the Indian Ocean basin, and the Antarctic. Therefore it is worth to take a closer look at the drivers of the huge success of this unique country and its inhabitants.

Eighty-nine eucnemid genera occur in the region from South-east Asia to the south-west Pacific. The phylogenies of 84 of these were used together with the present-day distributions of the species to analyse the biogeographical history of the area. Fifty-seven genera shared a pattern coinciding with the traditional model of Laurasia–Gondwana break-up. Six genera showed a pattern contradicting the model. The remaining 21 genera neither supported nor refuted the model. Twenty-five genera were observed to include an Indomalesian clade younger than the South America–Australia connection. This biogeographical unit consisted of present-day South-east Asia and the Sunda islands, but did not include the Philippine Islands and Sulawesi. In addition to this Indomalesian clade, three separate clades involving northern Australia or New Guinea were observed, New Guinea–Australia, New Guinea–Philippines–Sulawesi and New Guinea–Fiji. The possible presence of four separate areas in the general region of New Guinea–north Australia as the result of the Cretaceous geological events is suggested. Three of these, in the area of present-day New Guinea, originally sharing sister-groups with the north-eastern Australian isolate, are regarded as the sources of the New Guinea–Indomalesia, New Guinea–Philippines and New Guinea–Fiji faunas after northward drifting of the Australian continent. During the Oligocene–Miocene these source areas were flooded and their original fauna lost. When the present-day New Guinea emerged, it was invaded from the north-eastern Australian region. This invasion created new New Guinea–Australia connections and brought in the sister-groups of the old New Guinea source areas as well. The eucnemids of Vanuatu, Samoa and Tonga are regarded as having originated in connection with dispersal from Fiji. The New Zealand fauna has strong, old connections with that of south-eastern Australia, but other complex connections are indicated. The Eocene Baltic Amber fauna agrees well with the results obtained from extant species. The species belonging to five fossil genera belong to Gondwanan groups that seem to have invaded the Holarctic via Central America. Four other fossil genera showing discordant patterns belong to the group of six genera exhibiting these aberrant patterns even today. The eucnemid fauna of the region is of Gondwanic origin. Only six Laurasian genera have invaded the area, all of them apparently quite recently.

Democracy, Human Rights, and Civil Society in South East Asia, Amitav Acharya, B.M. Frolic and Richard Stubbs, eds., Toronto: Joint Centre for Asia Pacific Studies, 2001, pp. 208This is an important volume on the hotly debated topic of democracy, human rights and civil society in South East Asia, a region that has witnessed a confrontation between the old order of authoritarian regimes and strong states on one hand, and the new democratic forces embedded in an emerging civil society, on the other. The focus of the book is on the evolution of debates about democracy and human rights during the decade following the end of the Cold War in 1989 to the 1997–98 Asian economic crisis, with the latter being regarded as the watershed that unleashed the democratic forces. The book consists of nine chapters, plus an introduction and a conclusion, contributed by nine political scientists. Except for Johan Saravanamuttu, who is from the region under study, the other contributors are Southeast Asianists teaching at various universities in Canada, the United States, and Australia.

This articles explores the influences of political, cultural, historical and economic dynamics of the Asian region on what can be learnt about the region by English-speaking Australians and, therefore, for what can reasonably be known and said about early childhood programs by them. In doing so, it shows that learning about early childhood programs in the Asian region involves two levels of learning: learning about and learning what can be learnt about these services. The article concludes with suggestions for how English-speaking Australians might begin the process of learning about early childhood programs in the Asian region. The countries of the Pacific Rim [including Australia] face many common issues and problems in the provision of early childhood education. A great deal could be learned through international dialogue and collaborative research. (Feeney 1992, p.314) This articles explores the political and practical challenges and possibilities monolingual, English-speaking Australians face in taking up Feeney's suggestion to become involved in cross-cultural exchanges with early childhood colleagues in the Asian region.

Observations of upwelling along the south-east coast of South Australia during the summers of 1983 and 1984 are presented. In situ measurements were obtained from a number of current meters moored across the continental shelf near 37.5�S.,139.5�E. These were complemented by wind and sea level measurements along the coast and also monthly hydrographic surveys. Differences between summer and winter regimes are discussed in both physical and dynamical terms. The summer weather pattern gives rise to winds which are favourable to upwelling along this coast more than 50% of the time (i.e. winds from the south-east quarter). The evolution of two upwelling events and the associated shelf circulation are documented. Salient features include the offshore transport of water in a shallow surface layer 0 (20 m) in response to south-easterly winds; an onshore compensatory flow occurs almost immediately below. The summer thermocline shoals soon after the onset of winds favouring upwelling, leading to pronounced cross-shelf surface-temperature gradients with cooler (upwelled) water at the surface near the coast. The surfaced thermocline moves offshore and attains an equilibrium position in the vicinity of the shelf edge (after 4-5 days), as shown by infrared satellite images, while water from depths of 250-300 m encroaches onto the shelf. Alongshore currents reach speeds of more than 50 cm s-1 in the outer-shelf region and are strongly influenced by the position of the upwelling front. Brief comparisons are drawn with other upwelling regions.

Model simulations of residential segregation have shown that even modest levels of social homophily (or wishing to live near residents with similar social characteristics) gives rise to distinct spatial patterns of residential segregation. However, this proposition has been contested where social homophily is modest. This paper contrasts two explanations for urban sociospatial patterns (socioeconomic and demographic spatial patterns) in a region where social homophily is modest-South East Queensland (SEQ). The research question is whether sociospatial patterns are better explained by social homophily or by structural homophily. In other words, are they better explained by residents wishing to live in neighborhoods with similar people (social homophily), or by residents with similar social characteristics finding similar neighborhood physical attributes important, and thus moving to neighborhoods with similar people (structural homophily). SEQ residents were asked how important various reasons were in choosing their neighborhood. The survey data were linked to neighborhood social characteristics from census data with the aid of geographic information systems. Six neighborhood social characteristics in SEQ were investigated. Social homophily explained a small, though statistically significant, level of spatial variation in socioeconomic and ethnic (non-Western) environments. However, it did not explain any variation in the other four neighborhood social characteristics which related to household structure: that is, younger nonnuclear household environments; nuclear family environments; and older nonnuclear household environments, or disadvantaged environments. Moreover, structural homophily explained much more variation than did social homophily in all six neighborhood social characteristics. In regions such as SEQ, spatial patterns can largely be explained by structural homophily. Thus, modest levels of social homophily are not necessarily important in explaining sociospatial patterning.

The redlegged earth mite, Halotydeus destructor (Tucker) (Acari: Penthaleidae), is an important pest of pastures, broad-acre crops, and vegetables across southern Australia. Populations of H. destructor in Western Australia have been known to be resistant to pyrethroid and organophosphorus pesticides since 2006 and 2014, respectively. Resistant populations are currently widespread across Western Australia’s southern growing region but have, until now, remained undetected in the large south-eastern Australian range of H. destructor, despite ongoing resistance screening since 2006. Following reports of a field control failure in the Upper South East district in South Australia in 2016, resistance testing determined this South Australian population was resistant to pyrethroid and organophosphorus pesticides. The levels of resistance discovered were similar to resistant H. destructor populations in Western Australia, which are associated with chemical control failures. This work confirms for the first-time that pesticide resistant populations of H. destructor are no longer isolated to Western Australia.

East Asia is catching up with the rest of the world in establishing regional trade arrangements (RTAs). This region is responding to pressures from globalization, regionalism in the Americas and Europe, the rise of China and India, improved political relations in the region with the end of the Cold War, as well as market-driven trade and investment integration and the emergence of production networks. ASEAN formed the first RTA in 1992, and by the turn of the decade, ASEAN was signing or negotiating free trade agreements (FTAs) with Japan, China, South Korea, India, Australia–New Zealand, and the European Union. It also entered into bilateral FTAs with the United States and countries in Latin America, Africa, the Middle East, and South Asia. ASEAN is also considering an East Asian FTA. Can ASEAN remain in the driver's seat of regional integration and be an effective hub? The FTA proliferation also has important consequences and effects for East Asia and the world trading system.

Der volle Inhalt der QuelleAnnotation:
Blooms of phytoplankton (100-280 mg chlorophyll a m-1) occur on the continental shelf off Sydney in the spring of most years. These sudden chlorophyll increases (more than 10 times the normal algal biomass) are due to short-lived diatom blooms that evolve in a predictable sequence from small chainforming species (Nitzschia, Thalassiosira) to large centric species (Lauderia, Rhizosolenia) and eventually to large dinoflagellates (Protoperidinium). Two research cruises (October 1981, September 1984) were conducted to define the longshore extent of this phenomenon. Diatom blooms were widespread along the whole New South Wales coastline, occurring in the 700-km-long region from Cape Hawke in the north (32°S), where the East Australian Current separates from the coast, to Maria Island off Tasmania in the south (43°S). Hydrological mechanisms of these annually recurrent enrichments are related to the action of the East Australian Current and are unlike those triggering spring blooms in temperate European waters. Implications of these diatom blooms for coastal fisheries along the New South Wales coast are briefly discussed.

Snapper Chrysophrys auratus is a high-value food fish in Australia targeted by both commercial and recreational fisheries. Along the east coast of Australia, fisheries are managed under four state jurisdictions (Queensland, Qld; New South Wales, NSW; Victoria, Vic.; and Tasmania, Tas.), each applying different regulations, although it is thought that the fisheries target the same biological stock. An allozyme-based study in the mid-1990s identified a weak genetic disjunction north of Sydney (NSW) questioning the single-stock hypothesis. This study, focused on east-coast C. auratus, used nine microsatellite markers to assess the validity of the allozyme break and investigated whether genetic structure exists further south. Nine locations were sampled spanning four states and over 2000km, including sites north and south of the proposed allozyme disjunction. Analyses confirmed the presence of two distinct biological stocks along the east coast, with a region of genetic overlap around Eden in southern NSW, ~400km south of the allozyme disjunction. The findings indicate that C. auratus off Vic. and Tas. are distinct from those in Qld and NSW. For the purpose of stock assessment and management, the results indicate that Qld and NSW fisheries are targeting a single biological stock.A

The recent recognition of numerous small geological terranes in the Indo-Pacific region has revolutionised our understanding of geological and biogeographic processes. Most of these terranes rifted from Gondwana. The Shan-Thai terrane rifted from Australia in the Permian and collided with Indo-China in the Triassic. Parts of Sumatra and Kalimantan may have rifted from Australia in the Cretaceous and carried an angiosperm flora north. Other terranes, now dispersed in South-East Asia and in the Pacific were, at various times in the Cenozoic, part of the Australian continent. Faunal and floral mobilism to Fiji via the Solomons and Vanuatu was probably not difficult up to the late Miocene.

In June 2017, south China suffered from intense rainfall that broke the record spanning the previous 70 years. In this study, the large-scale circulations associated with the south China June rainfall are analyzed. The results show that the anomalous Pacific–Japan (PJ) pattern is a direct influence on south China June rainfall or East Asian early summer rainfall. In addition, the Australian high was the strongest in June 2017 during the past 70 years, which can increase the equatorward flow to northern Australia and activate convection over the Maritime Continent. Enhanced convection over the Maritime Continent can further enhance local meridional circulation along East Asia, engendering downward motion over the tropical western North Pacific and enhancing the western Pacific subtropical high (WPSH) and upward motion over south China, which increases the rainfall therein. In addition, a strong wave train pattern associated with North Atlantic air–sea interaction was observed in June 2017 at Northern Hemispheric mid- to high latitudes; it originated from the North Atlantic and propagated eastward to East Asia, resulting in an anomalous anticyclone over the Mongolian–Baikal Lake region. This anomalous anticyclone produced strong northerly winds over East Asia that encountered the southerly associated with the WPSH over south China, thereby favoring intense rainfall over the region. Case studies of June 2017 and climate research based on data during 1979–2017 and 1948–2017 indicate that the extremities of the atmospheric circulation over south Europe and Australian high and their coupling with the PJ pattern could be responsible for the record-breaking south China rainfall in June 2017.

The Australian Coastal Experiment was conducted off the east coast of New South Wales between September 1983 and March 1984. The experiment was conducted with arrays of current meters spanning the continental margin at three latitudes (37.5�, 34.5�, and 33.0�S.), additional shelf moorings at 29� and 42�S. coastal wind and sea-level measurements, monthly conductivity-temperature-depth probe/expendable bathythermograph (CTD/XBT) surveys, and two satellite-tracked buoys. Over the continental shelf and slope, the alongshore component of the current generally exceeded the onshore component, and the subtidal (<0.6 cpd, cycles per day) current variability greatly exceeded the mean flow. Part of the current variability was associated with two separate warm-core eddies that approached the coast, causing strong (>50 cm sec-1), persistent (>8 days), southward currents over the continental slope and outer shelf. Temperature and geostrophic velocity sections through the eddies, maps of ship's drift vectors and temperature contours at 250 m, and the satellite-tracked drifter trajectories showed that these eddies were similar in structure to those observed previously in the East Australian Current region. Both eddies migrated generally southward. Eddy currents over the shelf and slope were rare at Cape Howe (37.5�S.), more common near Sydney (34.5�S.), and frequent at Newcastle (33.0�S.), where strong northward currents were also observed. Near Sydney, the eddy currents over the slope turned clockwise with depth between 280 and 740 m, suggesting net downwelling there. Repeated CTD sections also indicated onshore transport and downwelling at shallower levels; presumably, upwelling occurred farther south where the eddy currents turned offshore. Periodic rotary currents over the continental slope near Sydney and Newcastle indicated the presence of small cyclonic eddies on the flank of a much larger anticyclonic eddy. Between early October and late January, no strong southward currents were observed over the continental margin near Sydney. Data from this 'eddy-free' period were analysed further to examine the structure and variability of the coastal currents. Much of this variability was correlated with fluctuations in coastal sea-level (at zero lag) and with the wind stress (at various lags). The coherence and phase relationships among current, wind-stress, and sea-level records at different latitudes (determined from spectral analysis and frequency-domain empirical orthogonal functions) were consistent with the equatorward propagation of coastal-trapped waves generated by winds in phase with those near Cape Howe. Time-domain empirical orthogonal functions show that the current fluctuations decayed with distance from shore and with depth, as expected of coastal-trapped waves.

An isozyme and morphological study of Senecio madagascariensis Poir. and closely related species in Australia, South Africa and Madagascar was used to investigate the most likely region of origin for Australian plants known as fireweed. Collections of seed and voucher specimens were made in New South Wales, KwaZulu-Natal, East and West Cape Provinces and southern Madagascar and specimens classified according to recognised taxa or descriptive variants. Plants were characterised by using isozyme analyses and morphological observations of both voucher specimens and achenes. Australian fireweed populations were found to be most closely related to populations of S. madagascariensis from KwaZulu-Natal in South Africa, and to be more distantly related to populations from East and West Cape Provinces in South Africa and from Madagascar. The implications of these findings are discussed in relation to efforts to locate host-specific biological control agents for fireweed.

A detailed study was undertaken on the pasture management practices of 146 producers across south-east Australia who participated in the Grassland’s Productivity Program (GPP) for 3 years between 1993 and 1997. The GPP was an extension program to assist wool producers to develop skills and gain confidence in their ability to manage more productive pastures on their farms. The program consisted of 50 farmer groups (200 farmers participating) spread across the 4 states of South Australia, southern New South Wales, Victoria and Tasmania. Each farmer established paired-paddocks on their own property to compare productive pastures with existing pastures. Productive pastures involve increased rates of fertiliser on pastures containing productive species, with stocking rate adjusted to consume available pasture. After 3 years of involvement in the GPP, there was a whole-farm increase in P fertiliser use by 6.3 kg P/ha, stocking rates by 2.6 dse/ha and annual pasture resowing by 0.9% of the farm, when averaged across the 146 participants. The participants were applying the productive pasture technology to almost a third of their properties in 1997 and the intention was to increase this to over half of their properties by 2000. The participants also changed farm management practices as the program effectively developed management skills. There were increases in the ability to assess pasture quality and quantity, livestock by weighing or physical assessment, and the ability to calculate per hectare production and per hectare gross margins. A high proportion of GPP participants were soil testing (0.92) and spring lambing (0.72) at the completion of the program. The results indicated that the adoption of productive pastures was generally consistent across south-east Australia for pastoral producers who participated in this program, although south-west Victorian and south-east South Australian GPP participants did increase whole-farm P application by more than GPP participants from outside that region. The widespread change in farming practice was attributed to the additive and interactive effect of the paired-paddock comparison, the guidance provided by the facilitator, the group interaction and the skills training. Each of these components of the paired-paddock model combined to form an effective agent for change to increase pasture productivity on these grazing properties.

The shift in Indian Ocean sea surface temperatures in 1976 led to a change in rainfall for the broad-scale winter annual grain cropping and pasture region in the south-west of Western Australia (the WA wheatbelt). Agriculture in the eastern part the WA wheatbelt was particularly sensitive to the change in rainfall because it is a marginal area for agronomic production, with low rainfall before changes in sea surface temperature. A second shift in sea surface temperature occurred in 2000, but there has been no analysis of the resulting impact on rainfall in the eastern WA wheatbelt. An analysis of rainfall pre- and post-2000 was performed for sites in the eastern WA wheatbelt in three groups: 19 sites in the west, 56 central, and 10 east. The analysis found a decline in growing-season rainfall (i.e. April–October), especially during May–July, post-2000. Rainfall declines of 49.9 mm (west group), 39.1 mm (central group) and 28.0 mm (east group) represented respective losses of 20.1%, 17.4% and 14.2% of growing-season rainfall. Increases in out-of-season rainfall in the respective groups of 31.0, 33.6, and 50.7 mm (57.8%, 60.8% and 87.6%) meant that annual rainfall changes were smaller than growing-season losses. The west and central groups lost 17.5 and 6.16 mm annual rainfall, whereas the east group gained 15.6 mm. Analysis of wheat yield indicated reductions of 13.5% (west) and 9.90% (central) in the eastern WA wheatbelt; the small group of east sites had a potential yield gain of 8.9% arising from the increased out-of-season rainfall. Further, increased out-of-season rainfall will exacerbate weed and disease growth over the summer fallow.

Development of hydrogen utilisation for energy applications has seen promising innovation towards the future prospect of clean and sustainable energy, benefitting various aspects of environmental, social, industrial and energy security. In the APEC region, several economies, such as the USA, China, Australia, Japan and South Korea, have shown interest in the development of hydrogen technology for energy applications. These economies have been devoting effort towards research and development programmes, pilot projects and, up to a certain point, implementing it in their communities. In addition, these economies each have their own tailored hydrogen roadmap or strategy, ensuring a smoother path towards hydrogen development. In this mini-review, we analysed the approaches of three selected economies in the East Asia region towards hydrogen technology, namely China, Japan and South Korea. Each of these economies have their own strategies and priorities towards the application, production and future development of hydrogen technology. This review also analyses the future possibilities for the integration of hydrogen technology into various sectors, as well as various constraints faced by each economy. Therefore, the review might serve as a valuable reference towards the feasibility of future hydrogen technology development in the East Asia and APEC region.

The islands of Polynesia make up the largest group among the islands in the Pacific ocean. This group, in fact, consist of many islands forming a triangle. The main groups in the west are the Tongan, and Samoan and Ellice groups. The Cook, Society and Tuamotus lie in the east, with Easter Island as a far-off isolate, while the Hawaiian Islands and New Zealand are separated to the north and south respectively of the main west-east belt. The location of these islands between Asia in the west, Australia in the south and South America continent in the east is of considerable significance to the peopling and cultural development of the region. Many scholars have therefore been led to postulate the route of human movement into these scattered islands. Archaeological and anthropological researches have been carried out within the area to determine where the Polynesians originally come from. Various hypotheses have been proposed thereafter.

AbstractRecent marine heatwave (MHW) events in the Tasman Sea have had dramatic impacts on the ecosystems, fisheries, and aquaculture off Tasmania’s east coast. However, our understanding of the large-scale drivers (forcing) and potential predictability of MHW events in this region off southeast Australia is still in its infancy. Here, we investigate the role of oceanic Rossby waves forced in the interior South Pacific on observed MHW occurrences off southeast Australia from 1994 to 2016, including the extreme 2015/16 MHW event. First, we used an upper-ocean heat budget analysis to show that 51% of these historical Tasman Sea MHWs were primarily due to increased East Australian Current (EAC) Extension poleward transports through the region. Second, we used lagged correlation analysis to empirically connect the EAC Extension intensification to incoming westward-propagating sea surface height (SSH) anomalies from the interior South Pacific. Third, we dynamically analyzed these SSH anomalies using simple process-based baroclinic and barotropic Rossby wave models forced by wind stress curl changes across the South Pacific. Finally, we show that associated monthly SSH changes around New Zealand may be a useful index of western Tasman Sea MHW predictability, with a lead time of 2–3 years. In conclusion, our findings demonstrate that there is potential predictability of advection-dominated MHW event likelihoods in the EAC Extension region up to several years in advance, due to the deterministic contribution from baroclinic and barotropic Rossby waves in modulating the EAC Extension transports.

Der volle Inhalt der QuelleAnnotation:
Three major water masses occur for all or part of the year within the shelf and slope region off southern Australia. A Leeuwin Current carries the warmest water mass of relatively low salinity into the region, principally along the shelf break as far east as 130�E. This water mass first enters the western end of the region in May, disappears from the eastern end after July and from the western end by September-October. A warm and very high salinity water mass is present in the central and eastern half of the Great Australian Bight for most of the year. This central Bight water mass drifts to the south-east and occupies much of the shelf and slope region east of 135�E., particularly in winter. A West Wind Drift cold water mass of lowest salinity is found throughout the year off the slope region of southern Australia and periodically intrudes into the shelf break, especially when the Leeuwin Current is weakly developed. The central Bight waters, which provide a second source of warm waters in the eastern half of the region, greatly complicate the interpretation from satellite imagery of warm waters in that region as being derived solely from the Leeuwin Current. Adequate salinity data and sea surface temperatures derived from satellite imagery are required to determine more accurately the eastward extent of the Leeuwin Current.

Public controversy over planned indirect potable reuse of wastewater has been a significant obstacle to implementing proposed schemes in the United States and Australia. Surveys of public attitudes to water reuse have generally shown lower acceptance of indirect potable reuse compared with other reuse options, such as irrigation. The south-east of England is projected to experience a shortfall in water supply by 2020 and the largest water utility in the region, Thames Water, is investigating indirect potable reuse as a potential new supply option. The indirect potable reuse feasibility studies include evaluation of the technology options and water quality as well as detailed consideration of public perception issues. As part of the work to address the latter, 2,000 Thames Water customers participated in an on-line survey of their attitudes to indirect potable reuse. The survey showed overall support for the idea of indirect potable reuse. The only demographic factor to show any significant difference from the whole sample was belief system, with Muslim respondents showing significantly less support than other groups. The survey results indicate that indirect potable reuse may be socially acceptable in the south-east of England, but that public engagement and participation in future decision making about indirect potable reuse will be important for the success of any particular proposal.

The scorpion-tailed orb-weaving spiders in the genus Arachnura Vinson, 1863 (Araneidae Clerck, 1757) are revised for Australia and New Zealand. Arachnura higginsii (L. Koch, 1872) only occurs in Australia and A. feredayi (L. Koch, 1872) only in New Zealand. A single female collected in south-eastern Queensland (Australia) is here tentatively identified as A. melanura Simon, 1867, but it is doubtful that this species has established in Australia. Two juveniles from northern Queensland do not conform to the diagnoses of any of the above species and are illustrated pending a more thorough revision of the genus in South-East Asia and the Pacific region. An unidentified female from Westport (New Zealand) does not conform to the diagnoses of A. feredayi and A. higginsii, but is not described due to its poor preservation status. Arachnura caudatella Roewer, 1942 (replacement name for Epeira caudata Bradley, 1876), originally described from Hall Sound (Papua New Guinea) and repeatedly catalogued for Australia, is considered a nomen dubium.

From the beginning of the 21st century, Australia’s interests in the East Sea (The South China Sea to non-Vietnamese people) have been increasingly more evident. Among those, the benefits relating the status of a “middle power” and the tensions derived mainly from China's ambitions are the most prominent features. Regarding Australia’s interests in the East Sea, the author argues that Australia had better promote more practical contributions to accommodate its role and status in the Asia-Pacific region. In particular, Australia’s contributions should be based on code of conducts, international rules and norms. In this paper, the author focuses on three recommendations, including: (i) promoting cooperation in the East Sea complying with the principles and the respect for the law; (ii) promoting Security and Defense Policy in terms of soft alliances; (iii) coordinating with regional powers in search of solutions to manage conflicts in the East Sea.

Provision of information for the purposes of evaluating and monitoring recreation and tourism land use is a conceptually difficult task for economists and land managers. A range of techniques has been developed since the pioneering work of Clawson and Knetsch in the 1960s to estimate the market value of recreation and tourism in natural areas. These techniques involve a number of conceptual and practical difficulties when used for environmental auditing and evaluation purposes. This article outlines the process of evaluating recreation and tourism on public lands in order to provide information for an environmental audit of the Upper North East region of New South Wales. The range of market and non-market values associated with tourism and recreation on public lands is based on existing studies of the region. The values of commercial production, recreation and tourism on public lands are compared within a structural model (input–output) of the regional economy.

The subtropical rainforests of South East Queensland are relatively understudied but their importance for conservation has recently been highlighted, with the Sunshine Coast region identified as an area of high diversity, second to the Border Ranges. We measured phylogenetic diversity at a fine scale to identify areas of high diversity and dissimilarity across the Sunshine Coast, within the Forest of East Australia biodiversity hotspot. Edaphic and climatic influences were incorporated in the analysis to test their relevance to diversity in the region, and to aid the identification of local diversity hotspots. The Sunshine Coast was found to be phylogenetically even overall and had a high proportion of even sites (91 out of 109), consistent with the identification of refugia at a larger scale. The Blackall Range was identified as a local centre of diversity but it has been extensively cleared. Contrary to expectation, coastal lowland sites were phylogenetically even, suggesting potential localised stability or strong connectivity to refugia. These results reiterate the high conservation value of the region in general, particularly for the remnant areas of rainforest on the Blackall Range.

The use of a TIMERITE® spring spray to control redlegged earth mite (RLEM), Halotydeus destructor (Tucker) (Acari: Penthaleidae), in annual pastures was evaluated on farms across Australia. RLEM populations in autumn in the treatments sprayed in spring 1998 and 1999 were 97% lower in 1999 and 97% in 2000 in the western region (Western Australia), and 93% lower in 1999 and 93% in 2000 in the eastern region (Victoria, New South Wales and South Australia). At sites in the west, control of RLEM resulted in significant increases in subterranean clover seed yield in 1999 and in clover seedling numbers in autumn 1999 and 2000. Penthaleus major (blue oat mite) populations in autumn were 60% lower in sprayed treatments, but Sminthurus viridis (lucerne flea) populations were not affected. Differences in weather between the west (where there is a hot, dry summer) and the east (where temperature and rainfall regimes are more variable in spring and early summer) seem to cause greater RLEM control and greater benefits in subterranean clover seed yield and seedling numbers with a spring spray in the west.

Although the Indo-Pacific is the global centre of diversity for the heterobranch sea slugs, their distribution remains, in many places, largely unknown. On the Australian east coast, their diversity decreases from approximately 1000 species in the northern Great Barrier Reef to fewer than 400 in Bass Strait. While occurrence records for some of the more populated sections of the coast are well known, data are patchy for more remote areas. Many species have very short lifecycles, so they can respond rapidly to changes in environmental conditions. The New South Wales coast is a recognised climate change hot-spot and southward shifts in distribution have already been documented for several species. However, thorough documentation of present distributions is an essential prerequisite for identifying further range extensions. While distribution data are available in the public realm, much is also held privately as photographic collections, diaries and logs. This paper consolidates the current occurrence data from both private and public sources as part of a broader study of sea slug distribution in south-eastern Australia and provides an inventory by region. A total of 382 species, 155 genera and 54 families is reported from the mainland coast of New South Wales.

AbstractThick successions of turbidites are widespread in the Ross–Delamerian and Lachlan orogens and are now dispersed through Australia, Antarctica and New Zealand. U-Pb detrital zircon age patterns for latest Precambrian, Cambrian and Ordovician metagreywackes show a closely related provenance. The latest Neoproterozoic–early Palaeozoic sedimentary rocks have major components, at c. 525, 550, and 595 Ma, i.e. about 40–80 million years older than deposition. Zircons in these components increase from the Neoproterozoic to Ordovician. Late Mesoproterozoic age components, 1030 and 1070 Ma, probably originate from igneous/metamorphic rocks in the Gondwanaland hinterland whose exact locations are unknown. Although small, the youngest zircon age components are coincident with estimated depositional ages suggesting that they reflect contemporaneous and minor, volcanic sources. Overall, the detrital zircon provenance patterns reflect the development of plutonic/metamorphic complexes of the Ross–Delamerian Orogen in the Transantarctic Mountains and southern Australia that, upon exhumation, supplied sediment to regional scale basin(s) at the Gondwana margin. Tasmanian detrital zircon age patterns differ from those seen in intra-Ross Orogen sandstones of northern Victoria Land and from the oldest metasediments in the Transantarctic Mountains. A comparison with rocks from the latter supports an allochthonous western Tasmania model and amalgamation with Australia in late Cambrian time.

The occurrence of grass tetany related deaths in cattle grazing pasture in the South East of South Australia is related to soil type. The greatest losses occur on the solodised solonetz soils, with few, if any, on the rendzina or siliceous sand soils in the region. Pastures from 3 soil types were sampled on 2 occasions during the growing period, and soils were sampled once. Comparisons were made for the pasture components of potassium (K), calcium (Ca) and magnesium (Mg) concentrations in soils, and K, Ca, Mg, nitrogen (N) and sulfur (S) concentrations in plants. In the July sampling, the mean herbage K/(Ca + Mg) ratio for both annual and perennial grass species grown on the solodised solonetz soils exceeded 2.2 but was below 2 for the other 2 soil types. At the same time the mean K/(Ca + Mg) ratio for soil-extractable cations was 0.10 for the solodised solonetz soils but only 0.058 and 0.025 for the rendzina and siliceous sand soils. A critical value for the K/(Ca + Mg) ratio for the soil extractable cations of 0.07-0.08 is suggested. Of the 22 sites in the investigation, grass tetany deaths had occurred on 9 within the previous 5 years; all of these were classified as solodised solonetz soils. Deaths were reported in late autumn and winter, and in all cases the dominant pasture species growing at these sites in July were grasses. It is suggested that deaths ceased in spring because there was either a change to legume dominance or an increase in air temperature.

Mesoproterozoic felsic magmatism of the Gawler Range Volcanics and Hiltaba Suite granites occurred at 1585–1595 Ma across much of the Gawler Craton, South Australia. Nd isotopic analysis of this felsic magmatism, combined with petrological and geochemical arguments, suggest derivation by partial melting of both Paleoproterozoic and Archean crust. The majority of samples analyzed have Nd isotopic and geochemical characteristics compatible with the involvement of Paleoproterozoic crust stabilized during the 1.85–1.71 Ga Kimban orogeny as sources for the Mesoproterozoic magmatism; others require derivation from sources dominated by Archean rocks. This cycle of Paleoproterozoic crustal stabilization followed by involvement of this crust Mesoproterozoic felsic magmatism is one previously documented from many parts of Mesoproterozoic Laurentia. On the basis of models proposing East Australia–Antarctica to be the conjugate landmass at the rifted margin of western North America, it appears that the voluminous magmatism of South Australia is another example of a typically Mesoproterozoic style of magmatism linked to Laurentia. This Mesoproterozoic magmatism appears temporally linked to regional high-temperature, low-pressure metamorphism of the region, and together with the presence of mantle-derived magmas, implicates the operation of large-scale tectono-thermal processes in the origin of felsic magmatism at 1590 Ma.

Abstract. 2003 was a record year for wildfires worldwide. Severe forest fires killed four people, displaced 20 500 others and burnt 260 000 ha in South-East Australia in January 2003. The uncontrolled fires ignited in early January 2003 as a result of a prolonged El Niño drought in South-East Australia. Severe weather conditions resulted in a fast spread of the fires and poor air quality in a region where 70% of the population of Australia lives. We use state-of-art global chemistry and transport model GEOS-Chem in conjunction with ground- and space-based observations to study the ozone (O3) and aerosol enhancement due to fires. Firstly, the monthly mean surface O3 and Aerosol Optical Depth (AOD) in January 2003 are compared to January 2004 and, secondly, from sensitivity model simulations, four episodes are isolated and an attempt is made to quantify the contribution of the fires to air quality in south and South-East Australia. In January 2003 the observed monthly mean afternoon surface O3 in Victoria (VIC) and South Australia (SA) reached 27.5 ppb, which is 6.5 ppb (i.e. 30%) higher than in 2004. The simulated O3 is 29.5 ppb, which is 10 ppb higher than in 2004. While the model tends to overestimate the observed peak O3, it exhibits very good skill in reproducing the O3 temporal variability in January 2003 with a correlation of 0.83. In VIC, the air quality 4-h ozone (O3) standard exceedences are reported on 17, 24 and 25 January. On 12, 17, 24–25 and 29 January 2003, the observed O3 peaks above 40 ppb and the simulated fire contribution is higher than 10 ppb. During these 4 episodes, the range of observed O3 enhancement due to fires is 20–35 ppb, which is a factor of 3 to 5 higher than the monthly mean. The simulated fire O3 enhancement is in the range 15–50 ppb with a factor of 1.5 to 5 higher than the monthly mean. During two episodes, a well-formed surface wind channel stretches across the Tasman Sea facilitating the long range transport to New Zealand contributing to a 10% increase of surface O3. During the four episodes in January 2003, the observed AOD was up to a factor of five higher that the monthly mean AOD. The simulated and observed AODs agree on the spatial structure. Despite the model tendency to underestimate the AOD, it proves a useful tool in reconstructing the mostly patchy observations.

Five species of the nephilid genus Nephila Leach are found in the Australasian region, which for the purposes of this study was defined as Australia and its dependencies (including Lord Howe I., Norfolk I., Christmas I., Cocos (Keeling) Is), New Guinea (including Papua New Guinea and the Indonesian province of West Papua), Solomon Is, Vanuatu, New Caledonia, Fiji, Tonga, Niue, New Zealand and other parts of the south-west Pacific region. All species are redescribed and illustrated. Nephila pilipes (Fabricius) occurs in the closed forests of eastern and northern Australia, New Guinea, Solomon Is and Vanuatu (through to South-East Asia); N. plumipes (Latreille) is found in Australia (including Lord Howe I. and Norfolk I.), New Guinea, Vanuatu, Solomon Is and New Caledonia; N. tetragnathoides (Walckenaer) inhabits Fiji, Tonga and Niue; N. antipodiana (Walckenaer) occurs in northern Australia (as well as Christmas I.), New Guinea and Solomon Is (through to South-East Asia); and N. edulis (Labillardière) is found in Australia (including Cocos (Keeling) Is), New Guinea, New Zealand and New Caledonia. Epeira (Nephila) walckenaeri Doleschall, E. (N.) hasseltii Doleschall, N. maculata var. annulipes Thorell, N. maculata jalorensis Simon, N. maculata var. novae-guineae Strand, N. pictithorax Kulczyński, N. maculata var. flavornata Merian, N. pictithorax Kulczyński, N. maculata var. flavornata Merian, N. maculata piscatorum de Vis, and N. (N.) maculata var. lauterbachi Dahl are proposed as new synonyms of N. pilipes. Nephila imperialis var. novaemecklenburgiae Strand, N. ambigua Kulczyński, N. sarasinorum Merian and N. celebesiana Strand are proposed as new synonyms of N. antipodiana. Meta aerea Hogg, N. meridionalis Hogg, N. adelaidensis Hogg and N. meridionalis hermitis Hogg are proposed as new synonyms of N. edulis. Nephila picta Rainbow is removed from the synonymy of N. plumipes and treated as a synonym of N. edulis, and N. nigritarsis insulicola Pocock is removed from the synonymy of N. plumipes and treated as a synonym of N. antipodiana. Allozyme data demonstrate that N. pilipes is distinct at the 80% FD level from N. edulis, N. plumipes and N. tetragnathoides. Nephila plumipes and N. tetragnathoides, deemed to represent sister-taxa owing to the shared presence of a triangular protrusion of the male pedipalpal conductor, were found to differ at 15% FD in the genetic study. No genetic differentiation was found between 10 populations of N. edulis sampled across mainland Australia. Species of the genus Nephila have been extensively used in ecological and behavioural studies, and the biology of Nephila species in the Australasian region is extensively reviewed and compared with studies on Nephila species from other regions of the world.

A 50-yr climatology (1957–2007) of subtropical cyclones (STs) in the South Atlantic is developed and analyzed. A subtropical cyclone is a hybrid structure (upper-level cold core and lower-level warm core) with associated surface gale-force winds. The tendency for warm season development of North Atlantic STs has resulted in these systems being confused as tropical cyclones (TCs). In fact, North Atlantic STs are a regular source of the incipient vortices leading to North Atlantic TC genesis. In 2004, Hurricane Catarina developed in the South Atlantic and made landfall in Brazil. A TC system had been previously unobserved in the South Atlantic, so the incidence of Catarina highlighted the lack of an ST climatology for the region to provide a context for the likelihood of future systems. Sixty-three South Atlantic STs are documented over the 50-yr period analyzed in this climatology. In contrast to the North Atlantic, South Atlantic STs occur relatively uniformly throughout the year; however, their preferred location of genesis and mechanisms for this genesis do exhibit some seasonal variability. Rossby wave breaking was identified as the mechanism for the ST vortex initiation for North Atlantic STs. A subset of South Atlantic STs forms via this mechanism, however, an additional mechanism for ST genesis is identified here: lee cyclogenesis downstream of the Andes in the Brazil Current region—an area favorable for convection. This formation mechanism is similar to development of type-2 east coast lows in the Tasman Sea off eastern Australia.
