The aim of this study was to reveal the branches of the descending palatine artery, and its relation to the vomeronasal organ inAngoragoats. For this purpose, ten heads of adultAngoragoats obtained from a slaughterhouse were used. The ramifications of the latex enjected descending palatine artery and their vomeronasal organ-related findings were revealed by fine dissection and transverse sections. Arterial blood reached the caudally vomeronasal organ primarily via the sphenopalatine artery, and also cranially via a fine branch of the major palatine artery by crossing the palatine fissure. The average diameters of both the descending palatine artery and its branches were thicker on the left side than on the right, and its ramifications were not variable in this species.

Growth was recorded of captive marsupials in Australia, the sugar gliders (Petaurus breviceps) during 13 years and squirrel gliders (P. norfolcensis) for 3 years. Tables give age range for different stages of development of the young, and graphs give head, arm and leg lengths and bodyweight at ages up to 180 days. Another graph gives seasonal fluctuation of bodyweight in adults.

Trapping data of the mahogany glider, Petaurus gracilis, and the sugar glider, Petaurus breviceps, in sympatry, in north Queensland, were analysed with vegetation variables to determine the habitat relationships of these two species. The study area contained a trapping grid (80 traps) within an area of continuous forest and trapping transects within an adjacent area of fragmented forest (44 traps). The mahogany glider was trapped more often at 43 of the 124 locations (38 in the continuous and 5 in the fragmented forest), with the sugar glider dominant at 46 locations (18 in the continuous forest and 28 in the fragmented forest). The remaining 27 trap locations where gliders were caught did not favour either species. Eight trap locations within riparian rainforest had no captures of either species. The presence of mahogany gliders was significantly correlated with the presence of Corymbia clarksoniana, Eucalyptus platyphylla, the absence of Corymbia intermedia and Acacia mangium, and a small mid and upper canopy cover. In contrast, the presence of sugar gliders was most correlated with a large number of stems. When the presence of the mahogany glider was compared with that of the sugar glider with respect to various habitat variables for the entire study area, the mahogany glider was most associated with the presence of C. clarksoniana, Eucalyptus pellita, Lophostemon suaveolens, Melaleuca dealbata and a reduced lower and upper canopy. In contrast, the sugar glider was most associated with C. intermedia, A. mangium, a large number of potential food species, rainforest species and a dense mid and upper canopy cover.

Many of the 600 species of Acacia found in Australia form part of the diet of several groups of marsupials. Acacia foliage is generally high in tannins but is consumed by several folivorous possums and by some macropods (kangaroos and wallabies), but the macropods eat it mainly as dry leaf litter during times of food shortage (in dry seasons and drought). Acacia gum is an important diet component of two omnivorous possums (Petaurus breviceps, Gymnobelidius leadbeateri) and, to a lesser extent, two rat-kangaroos (Bettongia sp.). Acacia seeds are consumed by marsupials to a limited extent, but are an important seasonal component of the diet of the mountain brushtail possum (Trichosurus cunninghami), and possibly the tammar wallaby (Macropus eugenii) on Kangaroo Island. Likewise, Acacia arils (lipid-rich appendages to the seeds of some species) are an important seasonal component of the diet of the mahogany glider (Petaurus gracilis). Acacia pollen and nectar are consumed by several omnivorous possums (e.g., Petaurus norfolcensis) as well as by at least one species of rock-wallaby (Petrogale sp.), but the quantitative contributions made by these floral products to the protein and energy budgets of the consumers have been difficult to determine. Thus several parts of the Acacia plant are food resources for one or more groups of marsupials, but the contribution of the genus to marsupial nutrition is often overlooked.

Field trials were undertaken in box-ironbark woodland at Puckapunyal Military Area (PMA) in central Victoria between January 2000 and April 2001 to assess bait uptake by the brushtailed phascogale (Phascogale tapoatafa) and other small mammals during simulated fox baiting exercises. The systemic marker Rhodamine B was used in non-toxic fox baits (Foxoff®) to detect non-target bait consumption. The trials demonstrated that free-living brush-tailed phascogales, yellow-footed antechinus (Antechinus flavipes), sugar gliders (Petaurus breviceps) and common brushtail possums (Trichosurus vulpecula) were capable of accessing non-toxic fox baits buried under 10 cm of sand. Rhodamine B markings were detected in six (15%) of 40 P. tapoatafa captured during the study period. The implications of these results and future research needs are discussed.

Populations of the Squirrel Glider, Petaurus norfolcensis and the Sugar Glider, P. breviceps, are often sympatric and the two species are potential competitors for tree hollows. Their use of hollows and artificial nest-boxes was examined in a Box-Ironbark forest where natural hollows are scarce due to past forestry practices. We found gliders used hollows in the boles and branches of trees and in coppicing stumps. There was considerable interspecific overlap in the use of hollows and nest-boxes, both by gliders and other birds and mammals. Both gliders preferred hollows and nest-boxes with narrow entrances (<50 mm diameter). Petaurus breviceps preferred nest-boxes and possibly natural tree hollows with entrances too narrow for the larger P. norfolcensis. When abundant nest-boxes of this type were introduced at the study site, P. breviceps numbers increased and then decreased when the nest-boxes were removed. The results suggest that the larger P. norfolcensis monopolise the best available hollows. Petaurus breviceps numbers may have been limited by a lack of suitable hollows.
