Petauroides volans (Diprotodontia: Pseudocheiridae)

Dealing with sampling bias and inferring absence data to improve distribution models of a widely distributed vulnerable marsupial

“…The two variables identified as important in all Maxent models were mean_xveg and pp_annual. This is consistent with ecological knowledge on the greater glider: the species has a strong association with eucalypt forest (Harris & Maloney, 2010; Lindenmayer et al., 2011) and preference for larger contiguous patches of native vegetation (Youngentob et al., 2013). The importance of pp_annual likely relates to the role of water availability for keeping water balance (Foley et al., 1990; Rübsamen et al., 1984) and for influencing vegetation and foliage quality (Moore et al., 2004) (Appendix S5).…”

Population Viability of an Endangered Population of Greater Gliders (Petauroides volans) and Management Implications

“…Even though we used a more accurate sampling methodology when compared to those of Vinson et al [14], our results showed that the population of gliders at SMBNP remains at a low-density; >10 greater gliders per 1 km (of transect) is considered a high-density population [61]. The result of the density estimation at SMBNP is within the range of other populations, e.g., 0.01 to 3.8 gliders/ha [2,8,14,27,43]. Using the double-observer distance method, we found 0.08 fewer gliders/ha than Vinson et al [14].…”

“…Input values were determined based on the best available data; however, there are some values with a higher degree of uncertainty. For example, the mating system can vary within and across different populations and varies from monogamy to polygamy depending on population density [43]. In previous PVA research undertaken for southern greater gliders, both monogamy and polygamy have been selected [22,25].…”

Current estimates and vegetation preferences of an endangered population of the vulnerable greater glider at Seven Mile Beach National Park

“…Suitable habitat within the study area was determined based on known greater glider vegetation requirements (Comport et al . 1996; Harris & Maloney 2010; Lindenmayer et al . 2011b) and plant community type classifications (Mills & Associates 2006).…”
