Population ecology and captive breeding of Pseudomys novaehollandiae at Anglesea

The New Holland Mouse is critically endangered within Victoria. A decline in the species abundance resulted from below average rainfall and structural changes to habitat vegetation. A captive breeding program was established as part of the species recovery plan. Induced breeding throughout the year, under controlled conditions, was limited by the species aggressive behaviour.

Museums in a troubled world: renewal, irrelevance or collapse?

In the early 2000s the Orchestre Symphonique de Montréal (OSM), one of Montreal's foremost cultural institutions, underwent two upheavals. First management was thrown into turmoil by the unexpected departure of the OSM's celebrated music director, Charles Dutoit, just as the orchestra and its Swiss conductor were about to mark 25 years of successful partnership with celebrations planned for the 2002-03 season. Then, in May 2005, the orchestra's management and board were faced with a strike by the orchestra's musicians. The authors describe the efforts of the orchestra's general manager, Madeleine Careau, to revive its fortunes, notably through a campaign to restore the OSM's prestige, which had been severely eroded by these two events. With the support of internal and external collaborators, Careau turned her attention to the most pressing issues, namely the choice of a new conductor, the orchestra's planned new concert hall and the creation of a foundation to ensure stable, long-term financing for the OSM. To help bring this recovery plan to fruition, Careau drew on her extensive network of contacts. An all-female leadership team was formed at the OSM, as Careau called on Melanie La Couture (CEO), Helene Desmarais (deputy board chair) and Monique Jérôme-Forget (chair of the Quebec treasury board) to use their talents, expertise and influence to give new lustre to the OSM at home and abroad.

The impact of grazing by eastern grey kangaroos (macropus giganteus) on vegetation recovery after fire at Reef Hills regional park, Victoria

In southeastern Australia ecological burning is frequently used to maintain a number of plant and animal populations. However, many of these prescribed fires are small, and may focus intense grazing activity on new regrowth. At Reef Hills Regional Park, Victoria shrub species have senesced, presumably due to the absence of fire. Ecological burning may be necessary to promote regeneration, however, the population density of the Eastern Grey Kangaroo (Macropus giganteus) is high (approx 38 per km2), and grazing pressure presents a significant risk to postfire vegetation recovery. An assessment of grazing patterns and their effects on postfire recovery was carried out at Reef Hills Regional Park through grazing exclusion plots. Preferential grazing by Eastern Grey Kangaroos occurred on small burnt plots compared to adjacent unburnt areas as determined by faecal pellet counts. On burnt areas, there was a significant reduction in shrub diversity on grazed plots compared to ungrazed plots. Most observations of kangaroos were of animals grazing on farmland surrounding the Park, and it is likely that any burning might shift grazing from farmland to burnt areas when new growth occurs. This needs to be considered before any ecological burn plan is applied to manage vegetation communities, particularly if the plan requires small areas to be burnt. We recommended that a large area up to 200 ha area be burnt and monitored to determine whether burning larger areas disperses grazing pressure from macropods to a level where impacts on vegetation are reduced and localized plant extinctions do not occur.

An effective and efficient testing methodology for correctness testing for file recovery tools

We hereby develop an effective and efficient testing methodology for correctness testing for file recovery tools across different file systems. We assume that the tool tester is familiar with the formats of common file types and has the ability to use the tools correctly. Our methodology first derives a testing plan to minimize the number of runs required to identify the differences in tools with respect to correctness. We also present a case study on correctness testing for file carving tools, which allows us to confirm that the number of necessary testing runs is bounded and our results are statistically sound.
