Abstract (sommario):

A new species of the caprellid genus Paraproto, P. murrayae n. sp. is described based on specimens collected from New South Wales, Australia. The new species was collected from brown algae in shallow water (16–19 m deep). Paraproto murrayae n. sp. is very similar to P. tasmaniensis Guerra-García & Takeuchi, 2004 but can be distinguished mainly by the following characteristics: (1) adults of P. murrayae are significantly smaller than P. tasmaniensis (5–6 mm and 10–11 mm respectively); (2) in larger males of P. tasmaniensis, gnathopod 2 is inserted on the anterior half of pereonite 2, rather than the posterior half as in P. murrayae; (3) the dactylus of the male gnathopod 2 is thickened medially in P. murrayae, but not thickened in P. tasmaniensis; (4) the setal formula of mandibular palp is 1-3-1 in P. murrayae versus 1-9-1 or 1-10-1 in P. tasmaniensis; (5) the lower lip is glabrous in P. murrayae but strongly setose in P. tasmaniensis; and (6) the anterolateral projections on pereonite 2 are lacking or vestigial in males of P. murrayae rather than distinct as in P. tasmaniensis. An illustrated key to the species of Paraproto is provided.

Abstract (sommario):

St John Ambulance is a household name synonymous with the teaching and provision of firstaid. Recently the organisation has developed pre-hospital emergency care services through theintroduction of the St- John Ambulance Australia Advanced Casualty Management Team inNew South Wales. The Advanced Casualty Management Team represents a move away fromthe practice of first aid by lay personnel and is a natural extension of the traditional workand principles of St John Ambulance. This article provides an overview of the AdvancedCasualty Management Team and discusses its contribution to pre-hospital trauma caredelivery.

Abstract (sommario):

While many studies investigated the higher morbidity and mortality levels ofindigenous Australians in the high-density indigenous areas in the Northern Territory,Western Australia and South Australia, few examined the situation in New SouthWales, where more than 28% of the indigenous population lives. Admissions to acutepublic and private hospitals in New South Wales for 1989?1995 are used in the studyreported here to examine indigenous health and its differential patterns by diseasecategories. The study allowed for the monitoring of disease groups with particularlyhigh indigenous admissions and, accordingly, pinpointed areas for improvement. Age-standardisedestimates for the indigenous population are provided. Age compositionof admissions for each disease category and admissions by residential area are alsoestimated.

Testo completo

Abstract (sommario):

The theory of a nineteen-year climate cycle put forward by acclaimed New SouthWales Government Astronomer Henry Chamberlain Russell is arguably one of his least successful contributions to science. Yet his ability to draw global connections made Russell a pioneer in the field of climate science— one whose innovative thinking helped prepare the way for much later achievements in the field of seasonal prediction. While controversial, Russell's theory sparked intense interest in meteorology and climate cycles and, at a time when extreme weather events were putting pressure on agriculture and pastoralism in New South Wales, it addressed the question of whether the Australian climate was undergoing permanent change. An historical understanding of ideas about climate cycles illuminates current debates on how to address the problems associated with anthropogenic climate change.

Abstract (sommario):

In 1994 the New South Wales Casemix Area Network initiated a study to developa classification and funding model for sub-acute and non-acute care. Thirty-fiverehabilitation, geriatric, psychogeriatric and palliative care services were recruited intothe study throughout eight area health services. The aim of the first phase, summarisedhere, was to capture and analyse a sufficiently large quantity of data to select thosevariables most likely to predict resource utilisation, for subsequent use in a detailedcosting study.It is known that acute care diagnosis related groups are not predictive of costs in sub-acutecare. This phase of the project confirmed that, in New South Wales, the mostpredictive variables were case type, functional status measures, impairment type forrehabilitation, phase for palliative care and severity of symptoms for palliative care.The resultant Phase 1 casemix classification, which has built on recent United Statesexperience and studies in other Australian States, has been termed the New SouthWales Sub-Acute and Non-Acute Patient (SNAP) Version 1 classification.

Testo completo

Abstract (sommario):

A total of 276 red foxes (Vulpes vulpes) was captured over 40 597 trap-nights during 1994–96 at three separate sites in central New South Wales, resulting in an overall trapping efficiency of one fox per 147 trap-nights. Trapping using multiple trap sets placed at carcases was 3.2 times more efficient than trapping using single trap sets. During 1994–95, when two of the sites suffered a severe drought, fox abundance declined to less than 0.2 foxes km–1 of spotlight transect; trapping efficiency at those sites also declined, to an average of one fox per 315 trap-nights. Mean trapping efficiency for non-drought periods was one fox per 135 trap-nights, 2.3 times more efficient than during the drought period. In 1995 and 1996, 353 foxes were shot in areas adjacent to each site. This gave the opportunity to compare sex and age biases between the trapped and shot samples: the ratio of males to females was significantly higher in the trapped sample than in the shot sample, and there was also a significantly higher ratio of adults to juveniles in the trapped sample than in the shot sample.

Testo completo

Abstract (sommario):

Antechinus mysticus sp. nov. occurs in coastal Australia, ranging from just north of the Queensland (Qld)/New SouthWales (NSW) border to Mackay (mid-east Qld), and is sympatric with A. flavipes (Waterhouse) and A. subtropicus VanDyck & Crowther in south-east Qld. The new species can be distinguished in the field, having paler feet and tail base thanA. flavipes and a greyish head that merges to buff-yellow on the rump and flanks, compared with the more uniform brownhead and body of A. subtropicus and A. stuartii Macleay. Features of the dentary can also be used for identification: A.mysticus differs from A. flavipes in having smaller molar teeth, from A. subtropicus in having a larger gap between frontand rear palatal vacuities, and from A. stuartii in having a generally broader snout. Here, we present a morphologicalanalysis of the new species in comparison with every member of the genus, including a discussion of genetic structure andbroader evolutionary trends, as well as an identification key to species based on dental characters. It seems likely that theknown geographic range of A. mysticus will expand as taxonomic focus on the genus is concentrated in south-east Queensland and north-east New South Wales.

Abstract (sommario):

A taxonomic revision of Acacia aulacocarpa Cunn. exBenth. and its seven close relatives is presented. These species comprise theA. aulacocarpa group in the AcaciaMill. section Juliflorae and occur naturally in eastern and northernAustralia, New Guinea and Wetar, eastern Indonesia. In the past, the nameA. aulacocarpa has been widely misapplied. This speciesis relatively uncommon but has an extensive geographic range extending fromthe Atherton Tableland region in Queensland, south to northern New SouthWales. Acacia aulacocarpa var.fruticosa C.T.White is considered conspecific withA. aulacocarpa. The nameA. lamprocarpa O.Schwarz is reinstated for a northernAustralian taxon that extends from western Queensland through NorthernTerritory to the Kimberley region of Western Australia. Five new taxa aredescribed from A. aulacocarpa sens. lat., namelyA. celsa Tindale (Queensland),A. disparrima subsp. disparrimaM.W.McDonald & Maslin (northern New South Wales and Queensland),A. disparrima subsp. calidestrisM.W.McDonald & Maslin (Queensland), A. midgleyiM.W.McDonald & Maslin (Queensland) andA. peregrina M.W.McDonald & Maslin (New Guinea).A full description is provided for A. crassicarpa Cunn.ex Benth. Mainly on the basis of their mode of pod dehiscence, two subgroupswithin the A. aulacocarpa group are defined:A. aulacocarpa, A. celsa andA. disparrima comprise theA. aulacocarpa subgroup and have pods that dehisce alongthe dorsal suture; and A. crassicarpa,A. lamprocarpa, A. midgleyi,A. peregrina and A. wetarensiscomprise the A. crassicarpa subgroup and have pods thatdehisce along the ventral suture. All species in the group, including theIndonesian species A. wetarensis, are illustrated and akey to the taxa is provided. Acacia celsa,A. crassicarpa, A. peregrina andA. midgleyi have considerable potential for wood production in tropical plantation forestry.

Abstract (sommario):

Plimerite, ideally Zn (PO4)3(OH)5, is a new mineral from the Block 14 Opencut, Broken Hill, New SouthWales. It occurs as pale-green to dark-olive-green, almost black, acicular to prismatic and bladed crystals up to 0.5 mm long and as hemispherical aggregates of radiating acicular crystals up to 3 mm across. Crystals are elongated along [001] and the principal form observed is {100} with minor {010} and {001}. The mineral is associated with hinsdalite-plumbogummite, pyromorphite, libethenite, brochantite, malachite, tsumebite and strengite. Plimerite is translucent with a pale-greyish-green streak and a vitreous lustre. It shows an excellent cleavage parallel to {100} and {010} and distinct cleavage parallel to {001}. It is brittle, has an uneven fracture, a Mohs’ hardness of 3.5–4, D(meas.) = 3.67(5) g/cm3 and D(calc.) = 3.62 g/cm3 (for the empirical formula). Optically, it is biaxial negative with α = 1.756(5), β = 1.764(4), γ = 1.767(4) and 2V(calc.) of –63º; pleochroism is X pale-greenish-brown, Y pale-brown, Z pale-bluish-green; absorption Z > X > Y; optical orientation XYZ = cab. Plimerite is orthorhombic, space group Bbmm, unit-cell parameters: a = 13.865(3) Å, b = 16.798(3) Å, c = 5.151(10) Å, V = 1187.0(4) Å3 (single-crystal data) and Z = 4. Strongest lines in the X-ray powder diffraction pattern are [d (A˚ ), I, hkl]: 4.638, (50), (111); 3.388, (50), (041); 3.369, (55), (131); 3.168, (100), (132); 2.753, (60), (115); 2.575, (90), (200); 2.414, (75), (220); 2.400, (50), (221); 1.957, (40), (225). Electron microprobe analysis yielded (wt.%): PbO 0.36, CaO 0.17, ZnO 20.17, MnO 0.02, Fe2O3 29.82, FeO 2.98, Al2O3 4.48, P2O5 32.37, As2O5 0.09, H2O (calc) 6.84, total 97.30 (Fe3+/Fe2+ ratio determined by Mössbauer spectroscopy). The empirical formula calculated on the basis of 17 oxygens is Ca0.02Pb0.01Zn1.68Al0.60P3.09As0.01O17.00H5.15. The crystal structure was solved by direct methods and refined to an R1 index of 6.41% for 1332 observed reflections from single-crystal X-ray diffraction data (Mo-Kα radiation, CCD area detector). The structure of plimerite is isotypic with that of rockbridgeite and is based on face-sharing trimers of (Mϕ6) octahedra which link by sharing edges to form chains, that extend in the b-direction. Chains link to clusters comprising pairs of corner-sharing (Mϕ6) octahedra that link to PO4 tetrahedra forming sheets parallel to (001). The sheets link via octahedra and tetrahedra corners into a heteropolyhedral framework structure. The mineral name honours Professor Ian Plimer for his contributions to the study of the geology of ore deposits.

Smith, Grant A. "Seasonal climate summary for the southern hemisphere (autumn 2017): the Great Barrier Reef experiences coral bleaching during El Niño–Southern Oscillation neutral conditions". Journal of Southern Hemisphere Earth Systems Science 69, n. 1 (2019): 310. http://dx.doi.org/10.1071/es19006.

Testo completo

Abstract (sommario):

Austral autumn 2017 was classified as neutral in terms of the El Niño–Southern Oscillation (ENSO), although tropical rainfall and sub-surface Pacific Ocean temperature anomalies were indicative of a weak La Niña. Despite this, autumn 2017 was anomalously warm formost of Australia, consistent with the warming trend that has been observed for the last several decades due to global warming. The mean temperatures for Queensland, New South Wales, Victoria, Tasmania and South Australiawere all amongst the top 10. The mean maximum temperature for all of Australia was seventh warmest on record, and amongst the top 10 for all states but Western Australia, with a region of warmest maximum temperature on record in western Queensland. The mean minimum temperature was also above average nationally, and amongst top 10 for Queensland, Victoria and Tasmania. In terms of rainfall, there were very mixed results, with wetter than average for the east coast, western Victoria and parts of Western Australia, and drier than average for western Tasmania, western Queensland, the southeastern portion of the Northern Territory and the far western portion of Western Australia. Dry conditions in Tasmania and southwest Western Australia were likely due to a positive Southern Annular Mode, and the broader west coast and central dry conditions were likely due to cooler eastern Indian Ocean sea-surface temperatures (SSTs) that limited the supply of moisture available to the atmosphere across the country. Other significant events during autumn 2017 were the coral bleaching in the Great Barrier Reef (GBR), cyclone Debbie andmuch lower than average Antarctic sea-ice extent. Coral bleaching in the GBR is usually associated on broad scales with strong El Niño events but is becoming more common in ENSO neutral years due to global warming. The southern GBR was saved from warm SST anomalies by severe tropical cyclone Debbie which caused ocean cooling in late March and flooding in Queensland and New SouthWales. The Antarctic sea-ice extent was second lowest on record for autumn, with the March extent being lowest on record.

Abstract (sommario):

Abstract. The Integrated Marine Observing System (IMOS, www.imos.org.au), an AUD $150 m 7-year project (2007–2013), is a distributed set of equipment and data-information services which, among many applications, collectively contribute to meeting the needs of marine climate research in Australia. The observing system provides data in the open oceans around Australia out to a few thousand kilometres as well as the coastal oceans through 11 facilities which effectively observe and measure the 4-dimensional ocean variability, and the physical and biological response of coastal and shelf seas around Australia. Through a national science rationale IMOS is organized as five regional nodes (Western Australia – WAIMOS, South Australian – SAIMOS, Tasmania – TASIMOS, New SouthWales – NSWIMOS and Queensland – QIMOS) surrounded by an oceanic node (Blue Water and Climate). Operationally IMOS is organized as 11 facilities (Argo Australia, Ships of Opportunity, Southern Ocean Automated Time Series Observations, Australian National Facility for Ocean Gliders, Autonomous Underwater Vehicle Facility, Australian National Mooring Network, Australian Coastal Ocean Radar Network, Australian Acoustic Tagging and Monitoring System, Facility for Automated Intelligent Monitoring of Marine Systems, eMarine Information Infrastructure and Satellite Remote Sensing) delivering data. IMOS data is freely available to the public. The data, a combination of near real-time and delayed mode, are made available to researchers through the electronic Marine Information Infrastructure (eMII). eMII utilises the Australian Academic Research Network (AARNET) to support a distributed database on OPeNDAP/THREDDS servers hosted by regional computing centres. IMOS instruments are described through the OGC Specification SensorML and where-ever possible data is in CF compliant netCDF format. Metadata, conforming to standard ISO 19115, is automatically harvested from the netCDF files and the metadata records catalogued in the OGC GeoNetwork Metadata Entry and Search Tool (MEST). Data discovery, access and download occur via web services through the IMOS Ocean Portal (http://imos.aodn.org.au) and tools for the display and integration of near real-time data are in development.

Testo completo

Abstract (sommario):

Viewed from the 'Southern Europe', the theoretical/critical debate in the Anglo-Saxon world, in particular the ongoing debate at the American universities is perplexing. It is a world of opulence and loftiness, not in this case on the level of material wealth, but intellectual wealth. If we understand that the omnipresence of 'critical theory' has an inhibitive effect on a sensory relationship with architecture, and that dichotomies such as critical/projective are schematic, the truth is that we need to leave behind atavisms that diminish the approach in 'Southern Europe': the local against the global; the space against the images; the young against the old. Theory and criticism have much to gain from allowing themselves to be provoked by the unknown. I would like to concretize these ideas by revisiting two recent experiences: to the South, Cape Verde, and to the East, Macau. They are border situations of wealth and material prosperity in Macau; and of poverty and obstruction in Cape Verde. How are these territories read and criticized? The architecture we find there is outside the history based on the MoMA. In China one hears the echo of echoes, increasingly. In Africa, one can hear the distant resonance of those echoes. Where are we beyond 'post-criticism'.

Testo completo

Abstract (sommario):

Examination of new meristic data on sand lance (Ammodytes spp.) populations in Newfoundland coastal waters using a combination of discriminant function and modal analyses demonstrates for the first time that co-occurrence is a common feature of the distribution of the two species (A. dubius and A. americanus) provisionally considered to exist in the Northwest Atlantic. In addition, the consistency in the meristic counts of A. dubius between the offshore and inshore samples and the postulated spawning of A. dubius in Newfoundland coastal waters provides good evidence that A. dubius is reproductively isolated from A. americanus. Reanalysis of published data on the vertebral composition of sand lance in the Northwest Atlantic confirms the co-occurrence of A. americanus and A. dubius in inshore areas from West Greenland southwards to the Gulf of Maine. These new analyses taken together with a review of the major distinguishing characteristics of sand lance species in the North Atlantic waters lead us to conclude that the heterogeneous assemblage of sand lance found inshore from West Greenland southwards and offshore from Georges Bank southwards and which has traditionally been classified as A. americanus belongs to a single trans-Atlantic species, A. marinus.

Abstract (sommario):

AbstractThe Miocene–Quaternary Trans-Mexican Volcanic arc is thought to have grown southwards (i.e. trenchward) since the Pliocene. This theory is mainly supported by roughly N–S-directed polygenetic volcanic ranges along which volcanic activity migrates southwards with time. We investigated the eruptive history of one of these ranges, the Sierra Nevada (east boundary of Mexico City basin), by compiling literature ages and providing new K–Ar dates. Our K–Ar ages are the first ones for the northernmost Tláloc and Telapón volcanoes and for the ancestral Popocatépetl (Nexpayantla). The obtained ages reveal that the four stratovolcanoes forming the range worked contemporaneously during most of the Middle to Late Pleistocene. However, taking into account the onset of the volcanic activity, a southward migration is evidenced along the Sierra Nevada: volcanism initiated at its northern tip at least 1.8 Ma ago at Tláloc volcano, extended southwards 1 Ma ago with Iztaccíhuatl and appeared at its southern end 329 ka ago with the Nexpayantla cone. Such a migration would be most probably primarily driven by Cocos slab roll-back and steepening rather than by regional crustal tectonics, which played a secondary role by controlling the apparent alignment of the volcanoes.

Testo completo

Abstract (sommario):

Shipboard measurements from late 2006 made by the Danish Galathea 3 Expedition and satellite sea surface temperature images revealed a chain of cool and warm ‘mushroom’ dipole vortices that mixed warm, salty, oxygen-poor waters on and near the continental shelf of the Great Australian Bight (GAB) with cooler, fresher, oxygen-rich waters offshore. The alternating ‘jets’ flowing into the mushrooms were directed mainly northwards and southwards and differed in temperature by only 1.5°C; however, the salinity difference was as much as 0.5, and therefore quite large. The GAB waters were slightly denser than the cooler offshore waters. The field of dipoles evolved and distorted, but appeared to drift westwards at 5km day–1 over two weeks, and one new mushroom carried GAB water southwards at 7km day–1. Other features encountered between Cape Leeuwin and Tasmania included the Leeuwin Current, the South Australian Current, the Flinders Current and the waters of Bass Strait.

Abstract (sommario):

Archaeological evidence for prehistoric gardening practices in Polynesia includes stone boundary walls, storage pits and structures, drainage systems and evidence for the modification of soil, but often the remains of horticultural practise are ephemeral. Maori developed a range of novel modifications to their traditional horticultural methods which enabled the successful introduction of the range of Polynesian cultigens into the temperate New Zealand environment, the furthest southwards these crops were introduced. They modified the soil by adding charcoal, shell and alluvial gravels to change the friability and temperature retention, and stored tubers in semi-subterannean pits for the next growing season (Jones 1991: 14–8; Challis 1976). Here, we report what we believe is the first direct archaeological evidence for the actual layout of prehistoric kumara gardens in New Zealand. Our interpretation receives support from the accounts of early Europeans in New Zealand, including Joseph Banks and William Colenso.

Abstract (sommario):

I have reviewed data from Australian and Asian published sources and from my own observations in Victoria, New South Wales and Queensland as well as from hundreds of observers who have sent their observations directly to me for the decade 2011–2020. These data show that the average flock size of the White-throated Needletail Hirundapus caudacutus in Australia was 33, being nine smaller than the average for the previous decade. In the decade 2011–2020, we have also learnt that many of these birds migrate through southern Thailand to Malaysia, then into Indonesia following the archipelago to Papua New Guinea and then across Torres Strait to Cape York. We have also learnt that at least some of those breeding in northern Japan fly from various parts of Japan westwards to China, then southwards, then back eastwards over the Pacific Ocean passing north of the Philippines until north of New Guinea. Then they fly southwards over New Guinea to reach Cape York. When departing, these birds fly westwards over Australia, then northwards, leaving Australia from Western Australia or the Northern Territory. While in Australia, they are almost constantly on the move and, because they fly for 1–2 hours after dark as well as before sunrise, they can collide with and be killed by the blades of wind turbines. The ongoing loss of nesting hollows in the Needletail’s breeding grounds is still likely to be a major cause of the species’ decline, but wind turbines in Australia may present a new and emerging risk and further research is required to determine whether or not the numbers killed are significant. Experiments in Japan have shown for the first time that this species will nest in man-made nest boxes.

Testo completo

Abstract (sommario):

AbstractGneiss domes in the Himalaya and southern Tibet record processes of crustal thickening, metamorphism, melting, deformation and exhumation during the convergence between the Indian and Eurasian plates. We review two types of gneiss domes: North Himalayan gneiss domes (NHGD) and later domes formed by orogen-parallel extension. Located in the southern Tibetan Plateau, the NHGD are cored by granite and gneiss, and mantled by the Tethyan sedimentary sequence. The footwall of these were extruded southwards from beneath the Tibetan Plateau and subsequently warped into a domal shape. The second class of domes were formed during displacement on normal-sense shear zones and detachments that accommodated orogen-parallel extension during the Late Miocene. In some cases, formation of these domes involved an early stage of southwards-directed extrusion prior to doming. We review evidence for orogen-parallel extension to provide context for the formation of these gneiss domes. Compilations of pressure–temperature–time–deformation data and temperature–time paths indicate differences between dome types, and we accordingly propose new terminology. Type 1 domes are characterized by doming as an artefact of post-high-temperature exhumation processes in the Middle Miocene. Type 2 domes formed in response to exhumation during orogen-parallel extension in the Late Miocene that potentially post-dates south-directed extrusion.

Abstract (sommario):

AbstractThe Chacoan peccary Catagonus wagneri is the rarest and most threatened of the three extant species of peccary. Its presence has been recorded in the northern Dry Chaco ecoregion, which spans northern Argentina, western Paraguay and south-eastern Bolivia. However, distribution models based on its occurrence in Argentina have predicted that suitable habitat extends southwards into central Argentina, where the species was not previously recorded. We present several records of the species outside the currently accepted distribution, including the first two records in the west of Córdoba province, > 650 km south of the southern limit of the previously known distribution. The discovery of the Chacoan peccary in central Argentina could serve as a justification for the protection of Chacoan forests in this region, where deforestation rates are among the highest worldwide.

Abstract (sommario):

Rhinocerophis jonathani is one of the few species of the Neotropical pitvipers that inhabit xeric areas at elevations above 2000 m in the Andes. We redescribe the species based on new specimens found in southern Bolivia and northwestern Argentina and provide new data on lepidosis, coloration, hemipenial morphology and the first description of cranial osteology. Rhinocerophis jonathani exhibits a suite of unusual features that are of systematic value within bothropoid genera. We compare the species with the phenotypically similar R. alternatus and the probably sympatric R. ammodytoides to address phylogenetic affinities. The new localities for Rhinocerophis jonathani extend the known range of the species southwards, provide data on its habitat and are the first records of its presence in Argentina. This pitviper occurs in a tropical-subtropical transition area in the Southern Andes and is likely to be derived from the Chacoan fauna.

Abstract (sommario):

AbstractThe Loyalty Ridge lies to the east and NE of the Norfolk Ridge. The three main Loyalty Islands (Maré, Lifou and Ouvéa) emerge from the ridge at the same latitude as Grande Terre. The islands are uniformly composed of carbonate deposits, except for Maré, where Middle Miocene intra-plate basalts and associated volcaniclastic rocks form restricted outcrops. Miocene rhodolith limestones constitute the bulk of the carbonate cover of the three islands. On Maré, these platform accumulations are locally topped by a dolomitic hardground, which, in turn, is covered by Pliocene–Pleistocene coral-bearing formations. These coral reef constructions are preserved as elevated rims over all three islands and define an atoll stage in their development. The Pleistocene–Holocene palaeoshoreline indicators include fringing bioconstructions and marine notches and record both eustatic sea-level changes and tectonic deformation. The ridge has been in the forebulge region in front of the active Vanuatu subduction zone since the Pliocene and each of the three islands has been uplifted and tilted to varying degrees. Offshore, the Loyalty Ridge continues northwards to the d'Entrecasteaux Zone and southwards to the Three Kings Ridge. Although typically volcanic, the nature of the deep Loyalty Ridge remains unknown.
