... Red-tailed Black Cockatoos may be estimated by comparison with photographs taken of nestlings of known age or estimated more precisely from the length of the nestling's folded wing. Aging nestlings enables the calculation of laying and hatching dates. Clutch size, incubation and nestling periods...

...Ross Goldingay; David Newell Estimates of population size are fundamental to the development of effective management of threatened species. We conducted a tagging study of a population of the endangered Green and Golden Bell Frog Litoria aurea at Port Kembla, on the New South Wales south coast...

The application of a method for the estimation of growth parameters from tagging data at unequal time intervals. North Atlantic Fish marking...

... sampling is labour-intensive and attained sample size is often not large enough to detect all species present. Therefore, we applied integrated rarefaction and extrapolation sampling curves and asymptotic analysis to estimate species richness. We observed 103 species of rotifers, 29 species of cladocerans...

... into dingo populations, particularly in southeastern Australia, and the impact this has on conservation goals. However, the discovery of biogeographic subdivision within dingoes raises questions about the accuracy of the current methods used for estimating dog vs dingo ancestry. I caution scientists...

... collection. In addition, long-term monitoring typically requires multiple observers, which may add observation bias to estimates of measured parameters. Thus there is an increasing need to develop new statistical techniques that take advantage of the power of long time-series datasets that also...

... using two types of aircraft: fixed-wing and helicopters. The NSW Commercial Kangaroo Harvest Management Plan 2017–21 states that harvest quotas are set at between 15 and 17% of the estimated kangaroo populations. As an example of the scale and intensity of kangaroo distribution and harvesting in NSW...

... of the wildlife-domestic interface is disease spread modelling. This can provide insight into how diseases spread within and between populations, and guide decision-making for disease control, response and surveillance programs. Specifically, quantitative estimation of contact rates permits such disease spread...

... Falsistrelle and Little Bent-wing Bat) as part of a pilot study for forest monitoring at a landscape-scale. Analyses that accounted for imperfect detection were used to: (1) generate detection probability and initial occupancy estimates for selected priority fauna species, and (2) undertake power analyses...

...A. R. Pople In order to monitor population trends through space and time, aerial surveys need to provide density estimates that are a constant proportion of the true population density and are therefore repeatable. Previous work has identified factors that affect the visibility of kangaroos from...

...L. Broome; F. Ford; M. Dawson; K. Green; D. Little; N. McElhinney The New South Wales population of the Mountain Pygmy-possum Burramys parvus was estimated at 500 adults in 8 km 2 of boulder-heath habitat during surveys in the 1980's. In 1989, this estimate was increased to 1312 adults based...

...Harry F. Recher ABSTRACT Birds were removed after counting numbers along a creek reserve established when old growth eucalypt forest on the Southern Tablelands of New South Wales was cleared for pine plantations. Removal ceased after the number of individuals collected exceeded the number estimated...

... and tend to impact more upon women and children. It is estimated that every year almost 500,000 people are maimed, permanently injured, or disabled by snakebite envenoming. The WHO has set a roadmap for the prevention, reduction, and control of snakebite envenoming, aiming to reduce snakebite deaths...
