A population of white-footed dunnarts (Sminthopsis leucopus) occurs in the Wet Tropics bioregion of tropical north Queensland, Australia separated by about 1800 km from conspecifics in temperate New South Wales, Victoria and Tasmania. We conducted targeted surveys for S. leucopus in north-east Queensland and obtained new records, including the first reported capture of the species in Queensland in 18 years. We assessed the genetic and morphological divergence of the north Queensland population against New South Wales, Victorian and Tasmanian S. leucopus, in conjunction with distribution and habitat differences, to assess whether this isolate should be described as a distinct taxon. Sequencing of the mitochondrial Cytochrome b gene revealed genetic divergence estimates of 2.3–2.8% and 4.3–4.8% between the north Queensland population and S. l. ferruginifrons (Victoria) and S. l. leucopus (Tasmania) respectively. Based on genetic divergence, cranial morphology, differences in habitat, and geographical isolation, we describe the north Queensland population as a new subspecies of Sminthopsis leucopus. We suggest a conservation classification of Endangered given its small distribution, apparent low density, tropical upland location and potential threats, especially related to climate change.
白足雀(Sminthopsis leucopus)的种群分布在澳大利亚昆士兰州北部的热带湿热带生物区，与温带的新南威尔士州、维多利亚州和塔斯马尼亚州的同类生物区相隔约1800公里。在昆士兰州东北部进行了针对性调查，获得了18年来首次在昆士兰州捕获的新记录。我们评估了北昆士兰种群与新南威尔士州、维多利亚州和塔斯马尼亚州的S. leucopus的遗传和形态差异，并结合分布和栖息地的差异来评估该分离物是否应该被描述为一个独特的分类单元。线粒体细胞色素b基因测序显示，北昆士兰种群与S. l. ferruginifrons(维多利亚)和S. l. leucopus(塔斯马尼亚)之间的遗传差异分别为2.3-2.8%和4.3-4.8%。基于遗传差异、颅骨形态、栖息地差异和地理隔离，我们将北昆士兰种群描述为一个新的浅槠亚种。考虑到其分布面积小、密度低、地处热带高地以及受气候变化的潜在威胁，建议将其列为濒危物种。

In New South Wales, legislation governing land clearing and development as it relates to koala conservation acts to prevent the destruction of habitat containing key tree species used by koalas. The identification of these key tree species is therefore critical to koala conservation. We aimed to compile a list of tree species used by koalas within the Wollondilly Shire region and investigate tree-use preferences. We radio-collared one female and four male koalas and tracked their movements over a period of 107–195 days. We conducted surveys within each koala’s home range to quantify the relative availability of each tree species, which we compared with their relative frequency of use. Koalas used 19 different tree species (17 during day, 12 during night), despite over 32 species being available. Eight species were preferentially used by one or more koalas; these were Eucalyptuts bosistoana, E. longifolia, E. puncata, E. crebra, E. globoidea, E. pilularis, E. tereticornis and Angophora floribunda. Two species were avoided: Corymbia gummifera and Acacia decurrens. Koalas consistently used larger trees relative to their availability, and we found a general but non-significant trend towards the use of larger trees at night compared with during the day. To achieve koala conservation, it will be necessary to preserve habitat patches comprising a diverse mixture of tree species and sizes, particularly trees >35 cm diameter at breast height (DBH), and to appropriately revegetate land with these criteria in mind.

Tree sap is important in the diet of the yellow-bellied glider (Petaurus australis). I investigated the use of 66 trees in sap feeding by gliders at 32 sites (equating to 32 glider groups) in eight surveys over 2 years in the Shoalhaven region of New South Wales to evaluate the potential to use such trees in population monitoring. I estimated the probability of detecting two different types of glider incision made on the sap trees within 0–3 months of a survey: one representing bouts of sap feeding and the other representing the testing of the suitability of these trees for sap feeding. The probability of detecting each type of incision varied by season, being lowest in autumn and highest in spring (feeding: 0.30 ± 0.03 (s.e.) to 0.51 ± 0.04; testing: 0.40 ± 0.04 to 0.63 ± 0.03). I also investigated whether detection of any new incision differed between individual sap trees at a site. The probability of detection per survey was equivalent (0.76 ± 0.03) between trees and between years. The incisions accumulate over a year, so scoring any incisions made since a previous annual survey will increase this probability. New incisions were detected in each of the two sample years at all sites indicating short-term stability in home range occupancy and demonstrating a useful method of population monitoring.
