The post-breeding migration of an adult male little eagle (Hieraaetus morphnoides) was followed from south-eastern Australia to the Northern Territory using a GPS satellite transmitter. The bird bred in open woodland habitat on the edge of the city of Canberra, Australian Capital Territory (ACT), before it flew more than 3300km in 18 days, to winter in an area of eucalypt savannah in the Northern Territory. It remained there for 59 days, within a range of ~30km2, after which the last signal was transmitted. The bird was subsequently resighted back in its ACT territory at the end of winter, thus completing a return migration. This is the first confirmation of post-breeding migration for the species.

Outcome Programme

From 1 January to 31 December 2018, thirty-six institutions around Australia participated in the Australian Enterococcal Sepsis Outcome Programme (AESOP). The aim of AESOP 2018 was to determine the proportion of enterococcal bacteraemia isolates in Australia that were antimicrobial resistant, and to characterise the molecular epidemiology of the E. faecium isolates. Of the 1,248 unique episodes of bacteraemia investigated, 93.5% were caused by either E. faecalis (54.2%) or E. faecium (39.3%). Ampicillin resistance was not detected in E. faecalis but was detected in 89.4% of E. faecium. Vancomycin non-susceptibility was not detected in E. faecalis but was reported in 45.0% of E. faecium. Overall 49.3% of E. faecium isolates harboured vanA or vanB genes. Of the vanA/vanB positive E. faecium isolates, 52.9% harboured vanA genes and 46.2% vanB genes; 0.8% harboured both vanA and vanB genes. The percentage of E. faecium bacteraemia isolates resistant to vancomycin in Australia is substantially higher than that seen in most European countries. E. faecium consisted of 59 multilocus sequence types (STs) of which 74.4% of isolates were classified into six major STs containing ten or more isolates. All major STs belong to clonal cluster (CC) 17, a major hospital-adapted polyclonal E. faecium cluster. The predominant STs (ST17, ST1424, ST796, ST80, ST1421, and ST262) were found across most regions of Australia. The most predominant clone was ST17 which was identified in all regions except the Australian Capital Territory and the Northern Territory. Overall, 55.8% of isolates belonging to the six predominant STs harboured vanA or vanB genes. The AESOP 2018 study has shown that enterococcal bacteraemias in Australia are frequently caused by polyclonal ampicillin-resistant high-level gentamicin-resistant vanA- or vanB-harbouring E. faecium which have limited treatment options.

As If

In the spring of 2016, The Australian Capital Territory (ACT) Planning Institute of Australia’s Young Planners had an idea, to create Canberra’s first parklet. Finally, in June 2018, the Parklet was built! It was a long and complicated journey to provide an urban renewal idea into the ACT, the result was a well utilised and loved piece of Canberra furniture. Although 4 minutes after the last barrier was removed, a car drove into the car space and it was as if the project had never happened! This article will explore the Canberra context, the feedback, how a temporary structure can change the urban fabric of the city and how Canberrans can learn from this experience.

Background: Population size determines the number of seats each Australian state and territory is entitled to in the House of Representatives. The Northern Territory (NT) and Australian Capital Territory (ACT) were allocated two and three seats, respectively, in the August 2017 determination, but by very small margins. Both territories risk losing a seat at the next determination. This would result in them having considerably more people per member of parliament than any of the states. Aims: This paper (1) provides modelling to support the consideration of alternative rules for determining membership entitlement to the House of Representatives which does not disadvantage the NT and ACT and (2) presents population projections for future determinations under the current and alternative rules. Data and methods: Population projections for the states and territories were produced for three demographic scenarios. The resulting numbers of seats for the NT and ACT were calculated for each scenario under the current and proposed alternative seat entitlement rules. Results: Under the existing rules the NT and ACT would only keep their current number of seats at the next determination if they experienced higher net in-migration than in recent years. Under the alternative seat entitlement rules suggested, the NT and ACT would be very unlikely to lose any seats and would almost certainly gain seats in ensuing decades. Conclusions: There is a case for re-examining the way the states and territories are allocated seats in the House of Representatives.

The Northern Territory Top End Health Service, Medical Entomology Section and the City of Darwin council carry out a joint Mosquito Engineering Program targeting the rectification of mosquito breeding sites in the City of Darwin, Northern Territory, Australia. In 2005, an investigation into potential subterranean stormwater breeding sites in the City of Darwin commenced, specifically targeting roadside stormwater side entry pits. There were 79 side entry pits randomly investigated for mosquito breeding in the Darwin suburbs of Nightcliff and Rapid Creek, with 69.6% of the pits containing water holding sumps, and 45.6% of those water holding sumps breeding endemic mosquitoes. Culex quinquefasciatus was the most common mosquito collected, accounting for 73% of all mosquito identifications, with the potential vector mosquito Aedes notoscriptus also recovered from a small number of sumps. The sumps were also considered potential dry season maintenance breeding sites for important exotic Aedes mosquitoes such as Aedes aegypti and Aedes albopictus, which are potential vectors of dengue, chickungunya and Zika virus. Overall, 1229 side entry pits were inspected in ten Darwin suburbs from 2005 to 2008, with 180 water holding sumps identified and rectified by concrete filling.

The aim of this study was to model pedestrian flow parameters needed in the design of pedestrian facilities. The study also characterized the flow with a view to understanding pedestrian interaction problems especially with regards to their congestion. Twenty-five locations across Kano metropolis were selected for study, thirteen locations from the city district while twelve sites were chosen from the Waje district. All the sites were high flow pedestrian locations that met the study objectives. The data was categorized into four; young male, adult male, young female and adult female. The results indicated that adult women walked faster than their male counterparts in the City district while young males were faster than the female. The adult female recorded an average speed of 73.90 m/min against the speed of 71.30 m/min for the adult male. The average characteristics of the pedestrian in the city district are speed 67.30 m/min; density 11.23 Ped/m2 and volume 33.60 Ped/m/min. In the Waje district, however, the male pedestrian whether adult or young walked faster than their corresponding female counterparts with speed of 71.45 m/min for the adult male and 59.90 m/min for the adult female. The young male was faster than the young female by 17.9%. The average pedestrian flow parameters for the Waje district indicated a combine speed of 60.21 m/min; density of 8.72 Ped/m2 and volume of 30.92 Ped/m/min. The pedestrians in the city district had a higher flow rate, higher density and higher speed than those of the Waje district. This means the city district is a little more concentrated than the Waje district in terms of pedestrian flow. The aggregate average flow parameters of pedestrians in the metropolitan area gave the following parameters: speed 68.92 m/min; density 10.03 Ped/m2 and volume 32.33 Ped/m/min. The predictive models for Kano showed a free flow speed of 59.55 m/min and a maximum flow rate of 73.0 Ped/m/min. Comparing the Kano pedestrian model with other countries it was found that the Kano pedestrian walked slower than pedestrians from Singapore and the United States

Southern Gulf Of Mexico

In the Gulf of Mexico, the bulk of published studies for sea turtles have focused on northern (United States) waters where economic resources are centered, with fewer studies in the southern portion of the basin, resulting in significant knowledge gaps in these underrepresented areas. Similarly, publications on adult sea turtles are dominated by research on females that come ashore to nest and can be readily studied (e.g., through the collection of biological samples and the application of satellite-telemetry devices), whereas information on adult male sea turtles is scarce. The goal of this paper is to begin filling these knowledge gaps by synthesizing available data on adult male sea turtles in the southern Gulf of Mexico. We used satellite-telemetry, boat- and drone-based surveys, and stranding records combined with ocean circulation modeling to better understand the spatial distribution of male loggerhead (Caretta caretta), green (Chelonia mydas), hawksbill (Eretmochelys imbricata), and Kemp’s ridley (Lepidochelys kempii) sea turtles in the southern Gulf of Mexico. These spatially explicit analyses will provide context for opportunistically collected data on male sea turtles and better contribute to the management and restoration of sea turtle populations that use the Gulf of Mexico. Moreover, this synthesis can serve as a launching point for directed studies on male sea turtles in this region.

Australian Magpie

In eastern Australia, two forms of the Australian magpie occur: a white-backed form and a black-backed form. These two forms hybridise across northern Victoria and into South Australia. In this study the response of territorial magpies to caged intruders was examined. Pairs of adult male magpies were introduced into territories. Both were adult black-backed birds, but in each case one of them had its back painted white. The pair was introduced to each territory twice, with the bird that was painted white differing between times. The experiment was run in a population of black-backed birds and a population in the hybrid zone containing white-backed, black-backed and hybrid birds. In both cases, the residents were more aggressive towards the intruder with the white-back than they were to the black-backed intruder. We suggest that this may be because a white-backed bird posed more of a threat to residents than a black-backed bird.
