Conservation activities, including translocations of threatened species, are increasingly important priorities for conserving biodiversity and culture on Indigenous-managed lands, which occupy over 20% of the Australian landmass. In the Anangu Pitjantjatjara Yankunytjatjara (APY) Lands of north-western South Australia, the Warru Recovery Team reintroduced the threatened black-footed rock-wallaby (warru) to Wamitjara in May 2018. We outline the unique planning and logistical issues inherent in securing support and involvement of Traditional Owners and Indigenous rangers for predator, weed and fire management, cross-fostering, captive breeding, monitoring and translocation of the rock-wallabies. Altogether, the project cost AU$3.86 million (actual – AU$1.86 million, in kind – AU$2.00 million) over 10 years of preparation and one year of post-translocation monitoring. This consisted of AU$1.18 million for cross-fostering and captive breeding at Monarto Zoo and a further AU$0.55 million for the construction and maintenance of a fenced exclosure in the APY Lands. It is estimated that AU$0.51 million of the total costs were directly attributed to working remote and Indigenous-owned land, with most of the remaining costs typical of other reintroduction programs. Large-scale reintroduction opportunities on Indigenous-managed land can provide considerable conservation outcomes as well as delivering cultural objectives and supporting employment.

AbstractPsittacid Adenovirus-2 (PsAdv-2) was identified in captive orange-bellied parrots (Neophema chrysogastor) during a multifactorial cluster of mortalities at the Adelaide Zoo, South Australia, and an outbreak of Pseudomonas aeruginosa septicaemia at the Tasmanian Department of Primary Industries, Parks, Water and Environment captive breeding facility, Taroona, Tasmania. This was the first time that an adenovirus had been identified in orange-bellied parrots and is the first report of PsAdv-2 in Australia. To investigate the status of PsAdv-2 in the captive population of orange-bellied parrots, 102 healthy birds from five breeding facilities were examined for the presence of PsAdv-2 DNA in droppings and/or cloacal swabs using a nested polymerase chain reaction assay. Additionally, eight birds released to the wild for the 2016 breeding season were similarly tested when they were recaptured prior to migration to be held in captivity for the winter. PsAdv-2 was identified in all breeding facilities as well as the birds recaptured from the wild. Prevalence of shedding ranged from 29.7 to 76.5%, demonstrating that PsAdv-2 is endemic in the captive population of orange-bellied parrots and that wild parrots may have been exposed to the virus. PsAdv-2 DNA was detected in both cloacal swabs and faeces of the orange-bellied parrots, but testing both samples from the same birds suggested that testing faeces would be more sensitive than cloacal swabs. PsAdv-2 was not found in other psittacine species housed in nearby aviaries at the Adelaide Zoo. The source of the infection in the orange-bellied parrots remains undetermined. In this study, PsAdv-2 prevalence of shedding was higher in adult birds as compared to birds less than one year old. Preliminary data also suggested a correlation between adenovirus shedding prevalence within the breeding collection and chick survival.

AbstractAn entomological radar was used to observe insect flight activity at a coastal locality in north-western Tasmania during the spring of 1973. Insects were regularly observed to take off at dusk, and local movements from nearby islands were detected on several occasions. Large-scale southward movements of insects across Bass Strait were also observed and were found to be associated with the warm anticyclonic airflows which occur ahead of a cold front. Light-trap catches indicated that the insects were noctuid moths, with Persectania ewingii (Westw.), Heliothis punctiger Wllgr. and Agrotis munda Wlk. dominant. The movements appear to have originated mainly in Victoria and south-eastern South Australia, but it is tentatively suggested that the ultimate source of the moths was in the region stretching westwards from north-western Victoria and south-western New South Wales towards the shores of the Spencer Gulf, South Australia.

Abstract Context Although the spatiotemporal dynamics of spruce budworm outbreaks have been intensively studied, forecasting outbreaks remains challenging. During outbreaks, budworm-linked warblers (Tennessee, Cape May, and bay-breasted warbler) show a strong positive response to increases in spruce budworm, but little is known about the relative timing of these responses. Objectives We hypothesized that these warblers could be used as sentinels of future defoliation of budworm host trees. We examined the timing and magnitude of the relationships between defoliation by spruce budworm and changes in the probability of presence of warblers to determine whether they responded to budworm infestation before local defoliation being observed by standard detection methods. Methods We modelled this relationship using large-scale point count surveys of songbirds and maps of cumulative time-lagged defoliation over multiple spatial scales (2–30 km radius around sampling points) in Quebec, Canada. Results All three warbler species responded positively to defoliation at each spatial scale considered, but the timing of their response differed. Maximum probability of presence of Tennessee and Cape May warbler coincided with observations of local defoliation, or provided a one year warning, making them of little use to guide early interventions. In contrast, the probability of presence of bay-breasted warbler consistently increased 3–4 years before defoliation was detectable. Conclusions Early detection is a critical step in the management of spruce budworm outbreaks and rapid increases in the probability of presence of bay-breasted warbler could be used to identify future epicenters and target ground-based local sampling of spruce budworm.

Investigation into the possible sources of primary infection by the fungus Ventruia inaequalis (Cooke) Wint. in spring has been carried out. The results present new information on the life cycle of the pathogen under South Australian conditions. Sources of primary infection, such 'as lesions on one-year-old wood or overwintering superficial conidia on the trees, do not appear important. Bud-scale infection of dormant buds has been shown, and its relative importance is discussed. Ascospores are the most important source of primary infection. Their period of discharge extends to a later date than previously reported for South Australia and is considered in relation to leader shoot and late summer spot infection.

Large Scale Project

In 2006, the town council of Slany decided to respond to the new trend of regional policy in the Central Bohemia region and focused on the revitalization of the historic core of the town. The large-scale project was assigned to a team of professionals (teachers and graduates of the Faculty of Civil Engineering of the Czech Technical University in Prague), led by Professor Sykora. Team members are to deal with issues of historical centre. The project presented a challenge to test theory, principles and procedures in practical design. The projected area featured Masaryk Square and 22 adjacent streets defined by the existing town walls. The reconstruction project of Vinarickeho Street was the first part of the overall project of revitalization of the historic core of the town chosen to implement. This reconstruction was one of the most technically, organizationally and financially complex works that have been undertaken in Slany recently. Construction started in November 2010 and lasted one year. Although this is a project of smaller scope, thanks to its complexity, sensitive approach and craftsmanship it brought the creators the price Construction of the Year 2012 in the Central Bohemia region and advanced to the second round in the competition Construction of the Year 2012 in Czech Republic.

The initial effect of two pulses of heavy cattle grazing on chenopod shrubland plants and invertebrates in northern South Australia was assessed in a two year trial. Both plant and invertebrate communities were structured by subhabitats which were defined by edaphic and water-distribution features. The cover of grasses and the dominant shrubs, Atriplex vesicaria and Maireana astrotricha, declined significantly following grazing but only total vegetation cover was significantly lower than controls one year after grazing. Plant species richness was not affected by the grazing pulses. Abundance of ants increased, but the responses of other invertebrates were inconsistent following grazing. Rainfall had a marked effect upon both plant cover and invertebrate abundance. Key words: chenopod shrublands, pulsed cattle grazing, Atriplex vesicaria, invertebrates, bioindicators

Abstract We present the South Galactic Pole (SGP) data release from the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey. These data combine both years of GLEAM observations at 72–231 MHz conducted with the Murchison Widefield Array (MWA) and cover an area of 5 113 $\mathrm{deg}^{2}$ centred on the SGP at $20^{\mathrm{h}} 40^{\mathrm{m}} < \mathrm{RA} < 05^{\mathrm{h}} 04^{\mathrm{m}}$ and $-48^{\circ} < \mathrm{Dec} < -2^{\circ} $ . At 216 MHz, the typical rms noise is ${\approx}5$ mJy beam–1 and the angular resolution ${\approx}2$ arcmin. The source catalogue contains a total of 108 851 components above $5\sigma$ , of which 77% have measured spectral indices between 72 and 231 MHz. Improvements to the data reduction in this release include the use of the GLEAM Extragalactic catalogue as a sky model to calibrate the data, a more efficient and automated algorithm to deconvolve the snapshot images, and a more accurate primary beam model to correct the flux scale. This data release enables more sensitive large-scale studies of extragalactic source populations as well as spectral variability studies on a one-year timescale.

Der vorliegende Beitrag beschäftigt sich mit bauherrenseitigem Projektkostencontrolling (PKC) bei Großbauprojekten unter Zuhilfenahme probabilistischer Methoden. Das dargestellte PKC-Konzept ermöglicht robuste Gesamtkostenprognosen und eine kontinuierliche Überwachung des Projektbudgets während der Planungs- und Ausführungsphase. Das Konzept basiert auf der in der ÖGG-Richtlinie Kostenermittlung für Projekte der Verkehrsinfrastruktur vorgegebenen Gliederung der Gesamtkosten, welche für die zusätzliche Anwendung in der Ausführungsphase fortgeschrieben wird. Um Unschärfen in der Kostenprognose mit ausreichendem Informationsgehalt zu berücksichtigen, wird das PKC-System mit aktuellen probabilistischen Methoden der Kosten- und Risikoanalyse verknüpft. &nbsp; Basierend auf den Erkenntnissen aus der praktischen Anwendung des erarbeiteten PKC-Konzepts wurde ein Leitfaden zur Gewinnung sowie zur zyklischen Aktualisierung von relevanten PKC-Daten erarbeitet. Die Anwendung des entwickelten Leitfadens wird anhand eines Beispielprojekts unter Zuhilfenahme der Kostencontrolling-Software RIAAT demonstriert. &nbsp; Die Erfahrungen aus der Anwendung des PKC-Konzepts und des Leitfadens zeigen den Mehrwert der Berücksichtigung von Kosten für Risiken und Marktentwicklungen in Sinne einer robusten Gesamtkostenprognose sowie Budgetpolitik. Die Anwendung von probabilistischen Methoden zur Berücksichtigung von Unschärfen erhöht die Aussagekraft der ermittelten Ergebnisse. Die detaillierten Ausführungen sowie die klaren Abgrenzungen der Verantwortlichkeiten, welche der Leitfaden vorgibt, helfen Fehler zu vermeiden sowie die Durchführung des Projektkostencontrollings effektiver zu gestalten.
