Phalangeriform marsupials have often been compared with primates because of similarity in the range of external morphology, ecological niches, and body size between the two radiations. We explore morphological convergence in the masticatory anatomy of strepsirrhine primates and phalangeriforms, through osteological measurements of the mandible and facial skeleton, and through dissection of the masticatory musculature, presenting new data on the arrangement and proportions of jaw adductors in phalangeriforms. Phalangeriforms and primates have a large number of shape differences in mandibular morphology. Despite these differences in shape on phylogenetic lines, dietary groups used to pool species of phalangeriforms and strepsirrhines also differed from each other in a range of shape variables. Notably, the striped possum (Dactylopsila), previously described as convergent with the aye-aye (Daubentonia), shares a number of features of mandibular shape with Daubentonia, and the exudate-feeding sugar-glider, Petaurus, shares shape features with gummivorous strepsirrhines. Petaurus also has long-fibered jaw adductors for its body mass, as would be expected for a species with a requirement for large gape. Phalangeriform species on the frugivore-folivore continuum were less clearly comparable to strepsirrhine species with similar diets. There are a number of significant dietary contrasts in osteological measurements, but in the masticatory muscles phalangeriforms did not meet all expectations based on available dietary data, highlighting the possible complexity of dietary adaptation in phalangeriform folivores.

“…Vegetation spatial data sets (Office of Environment & Heritage 2013, 2016) were obtained and merged across the entire study area. 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). Suitable habitat within the study area was clipped to cover only the area within the National Park creating an estimate of area size of suitable vegetation.…”

“…The greater glider (Petauroides volans) is an endemic Australian arboreal mammal that has become the focus of recent research (McLean et al 2018;Smith & Smith 2018;Emerson et al 2019;Vinson et al 2020) due to its high sensitivity to habitat destruction from land clearing for agriculture, logging and bushfires (Harris & Maloney 2010;McLean et al 2018). Greater gliders have a patchy distribution within eucalypt forests throughout eastern mainland Australia from south-eastern Victoria to north eastern Queensland (Harris & Maloney 2010;Smith & Smith 2018). Greater gliders are a eucalypt forest-dependent, selective folivore and obligate hollow-dependent species (Comport et al 1996).…”

“…Greater gliders are a eucalypt forest-dependent, selective folivore and obligate hollow-dependent species (Comport et al 1996). Greater gliders range in size from 700 to 900 g (P. v. minor) to 1000-1700 g (P. v. volans), which makes them relatively large in comparison to other hollow-dependent mammals (Gibbons & Lindenmayer 2002;Harris & Maloney 2010). Due to their size, relatively large hollows (>10 cm) in large diameter trees are used for shelter and nesting (Harris & Maloney 2010); though such hollows are known to take up to 150 years to form (Smith et al 2007;Harris & Maloney 2010).…”

This study aimed to provide accurate and current distribution and density estimates of the greater glider population size at Seven Mile Beach National Park, New South Wales Australia from extensive spotlight surveys. Distribution mapping of greater gliders and ArcGIS modelling allowed effective visual representation of the population's distribution and provided preliminary evidence of a vegetation preference for the species within the study area. Spotlight surveys revealed the population ranged from 0 to 1.13 (AE0.34) greater gliders per hectare; with an average of 0.41 greater gliders per hectare across Seven Mile National Park. An estimated total of 335 greater gliders could reside in the area. Vegetation surveys confirmed there was a higher encounter rate of greater gliders within Eucalyptus pilularis, blackbutt dominated forest. As expected, the number of suitable hollows was also an important factor affecting greater glider distribution. These findings have site-specific implications for a number of suitable management options (e.g. nest boxes, road crossing structures and glider poles).

“…We chose the greater glider for this study because it feeds almost exclusively on young leaves of eucalypts with the preferred species often the dominant tall eucalypts in the habitat. Usually the diet consists of 3–6 different species of Eucalyptus over a year [ 29 – 32 ] but in some locations (e.g. SE NSW), a single species such as E .…”

The Relative Concentrations of Nutrients and Toxins Dictate Feeding by a Vertebrate Browser, the Greater Glider Petauroides volans

Although ecologists believe that vertebrate herbivores must select a diet that allows them to meet their nutritional requirements, while avoiding intoxication by plant secondary metabolites, this is remarkably difficult to show. A long series of field and laboratory experiments means that we have a good understanding of the factors that affect feeding by leaf-eating marsupials. This knowledge and the natural intraspecific variation in Eucalyptus chemistry allowed us to test the hypothesis that the feeding decisions of greater gliders (Petauroides volans) depend on the concentrations of available nitrogen (incorporating total nitrogen, dry matter digestibility and tannins) and of formylated phloroglucinol compounds (FPCs), potent antifeedants unique to Eucalyptus. We offered captive greater gliders foliage from two species of Eucalyptus, E. viminalis and E. melliodora, which vary naturally in their concentrations of available nitrogen and FPCs. We then measured the amount of foliage eaten by each glider and compared this with our laboratory analyses of foliar total nitrogen, available nitrogen and FPCs for each tree offered. The concentration of FPCs was the main factor that determined how much gliders ate of E. viminalis and E. melliodora, but in gliders fed E. viminalis the concentration of available nitrogen was also a significant influence. In other words, greater gliders ate E. viminalis leaves with a particular combination of FPCs and available nitrogen that maximised the nutritional gain but minimised their ingestion of toxins. In contrast, the concentration of total nitrogen was not correlated with feeding. This study is among the first to empirically show that browsing herbivores select a diet that balances the potential gain (available nutrients) and the potential costs (plant secondary chemicals) of eating leaves. The major implication of the study is that it is essential to identify the limiting nutrients and relevant toxins in a system in order to understand feeding behaviour.
