Contrary to previous literature, P. xanthopus had not been recorded in western New South Wales before its existence was reported by Fox (1966). There is only one geographically isolated population of less than 250 animals in two separate colonies in the Gap and Coturaundee Ranges, where they are confined to two cliff systems and two outcrops. Their distribution is therefore more limited than first reported by Wilson et al. (1976). They were more widespread in the past, being found also in the Barrier and Bynguano Ranges. These conclusions have been reached from data collected from: (1) a large-scale low-level aerial survey and subsequent ground inspections to record this species' presence in specific locations in north-western New South Wales; (2) a systematic detailed survey of the Gap and Coturaundee Ranges to establish its pattern of habitat use from the accumulated density of faecal pellets; (3) low-level
aerial surveys over these and other areas, by helicopter, to confirm the results of earlier surveys and check on reported sightings. The results of this study are being used for the management of this rare rock-wallaby in New South Wales. It is recommend that this species be re-established in the Bynguano Range.

Annual aerial counts of kangaroos within randomly selected blocks of the western plains of New South
Wales showed that the numbers of kangaroos doubled between 1975-76 and 1982, and that the
widespread drought of 1982 reduced the populations on average by 43%. Localized reductions of similar
magnitude occurred after regional droughts in 1977 and 1980 within parts of the monitored area. The
observed trends in kangaroo numbers, with eastern and western blocks treated separately, were
correlated with annual rainfall with a time lag of 6 months in the response. The relationships show that
kangaroos reach their maximum rate of increase following rainfall 100 mm above the annual average in
the east and approximately 50 mm above the annual average in the west. At average annual rainfall
kangaroos increase at 25% (greys) and 35% (reds) per annum in the east and at 25% (greys) and 30% (reds)
per annum in the west. Rate of increase is zero when rainfall is 100 mm below average in the east and
approximately 60 mm below average in the west. When rainfall is below these values, kangaroo
numbers decline.

A review was conducted of literature relating to plagues of the house mouse in three agricultural regions of south-eastern Australia for the period 1900–70. Meteorological data, particularly in relation to rainfall, was surveyed during the same period. The two sets of data indicated that in each region plagues of the house mouse were preceded by drought conditions. The role of mouse predators and disease agents are discussed as possible explanations of this relationship.

Background: The COVID-19 pandemic has disrupted routine hospital services globally. This study estimated the total number of adult elective operations that would be cancelled worldwide during the 12 weeks of peak disruption due to COVID-19. Methods: A global expert response study was conducted to elicit projections for the proportion of elective surgery that would be cancelled or postponed during the 12 weeks of peak disruption. A Bayesian β-regression model was used to estimate 12-week cancellation rates for 190 countries. Elective surgical case-mix data, stratified by specialty and indication (surgery for cancer versus benign disease), were determined. This case mix was applied to country-level surgical volumes. The 12-week cancellation rates were then applied to these figures to calculate the total number of cancelled operations. Results: The best estimate was that 28 404 603 operations would be cancelled or postponed during the peak 12 weeks of disruption due to COVID-19 (2 367 050 operations per week). Most would be operations for benign disease (90·2 per cent, 25 638 922 of 28 404 603). The overall 12-week cancellation rate would be 72·3 per cent. Globally, 81·7 per cent of operations for benign conditions (25 638 922 of 31 378 062), 37·7 per cent of cancer operations (2 324 070 of 6 162 311) and 25·4 per cent of elective caesarean sections (441 611 of 1 735 483) would be cancelled or postponed. If countries increased their normal surgical volume by 20 per cent after the pandemic, it would take a median of 45 weeks to clear the backlog of operations resulting from COVID-19 disruption. Conclusion: A very large number of operations will be cancelled or postponed owing to disruption caused by COVID-19. Governments should mitigate against this major burden on patients by developing recovery plans and implementing strategies to restore surgical activity safely.
