EASTERN BARRED BANDICOOT Perameles Gunnii Mainland Subspecies Endangered Zoos Victoria’s Priority Species EASTERN BARRED BANDICOOT Perameles gunnii mainland subspecies Endangered The Eastern Barred Bandicoot wouldn’t be here without us. In 1988 it was estimated that the mainland subspecies had dwindled down to 200 animals living in Hamilton in western Victoria. In 1991 Zoos Victoria embarked on its commitment to the Eastern Barred Bandicoot and has bred over 690 since. Zoos Victoria is committed to Fighting Extinction We are focused on working with partners to secure the survival of our priority species before it is too late. Eastern Barred Bandicoots (EBB) were once widespread across the grasslands and grassy woodlands of western Victoria. These animals are now listed as extinct in the wild. Zoos Victoria has coordinated the Eastern Barred Bandicoot captive breeding program since 1991. Working closely with the Recovery Team, we also work to control introduced predators and manage habitat for reintroduction.

  • BANDICOTA INDICA, the BANDICOOT RAT 3.1 The
    CHAPTER THREE BANDICOTA INDICA, THE BANDICOOT RAT 3.1 The Living Animal 3.1.1 Zoology Rats and mice (family Muridae) are the most common and well-known rodents, not only of the fi elds, cultivated areas, gardens, and storage places but especially so of the houses. Though there are many genera and species, their general appearance is pretty the same. Rats are on average twice as large as mice (see Chapter 31). The bandicoot is the largest rat on the Indian subcontinent, with a body and head length of 30–40 cm and an equally long tail; this is twice as large as the black rat or common house rat (see section 3.1.2 below). This large size immediately distinguishes the bandicoot from other rats. Bandicoots have a robust form, a rounded head, large rounded or oval ears, and a short, broad muzzle. Their long and naked scaly tail is typical of practically all rats and mice. Bandicoots erect their piles of long hairs and grunt when excited. Bandicoots are found practically on the whole of the subcontinent from the Himalayas to Cape Comorin, including Sri Lanka, but they are not found in the deserts and the semi-arid zones of north-west India. Here, they are replaced by a related species, the short-tailed bandicoot (see section 3.1.2 below). The bandicoot is essentially parasitic on man, living in or about human dwellings. They cause a lot of damage to grounds and fl oorings because of their burrowing habits; they also dig tunnels through bricks and masonry.

  • Size Relationship of the Tympanic Bullae and Pinnae in Bandicoots and Bilbies (Marsupialia: Peramelemorphia)
    Size Relationship of the Tympanic Bullae and Pinnae in Bandicoots and Bilbies (Marsupialia: Peramelemorphia) by Melissa Taylor BSc This thesis is presented for the degree of Bachelor of Science Honours, School of Veterinary and Life Sciences, of Murdoch University Perth, Western Australia, 2019 Author’s Declaration I declare that this thesis is my own account of my research and contains as its main content work which has not previously been submitted for a degree at any tertiary education institution. Melissa Taylor iii Abstract Hearing is an important factor allowing species to obtain information about their environment. Variation in tympanic bullae and external pinnae morphology has been linked with hearing sensitivity and sound localisation in different mammals. Bandicoots and bilbies (Order Peramelemorphia) typically occupy omnivorous niches across a range of habitats from open, arid deserts to dense, tropical forests in Australia and New Guinea. The morphology of tympanic bullae and pinnae varies between peramelemorphian taxa. Little is known about the relationship between these structures, or the extent to which they vary with respect to aspects of ecology, environment or behaviour. This thesis investigated the relationship between tympanic bulla and pinna size in 29 species of bandicoot and bilby. Measurements were taken from museum specimens to investigate this relationship using direct measuring methods and linear dimensions. It was hypothesised that an inverse relationship between bullae and pinnae may exist and that species residing in arid regions would have more extreme differences. Environmental variables were examined to determine the level of influence they had on bullae and pinnae. This study found that there was a phylogenetic correlation between the structures and that they were significantly influenced by temperature (max/average) and precipitation (average).

  • Ba3444 MAMMAL BOOKLET FINAL.Indd
    Intot Obliv i The disappearing native mammals of northern Australia Compiled by James Fitzsimons Sarah Legge Barry Traill John Woinarski Into Oblivion? The disappearing native mammals of northern Australia 1 SUMMARY Since European settlement, the deepest loss of Australian biodiversity has been the spate of extinctions of endemic mammals. Historically, these losses occurred mostly in inland and in temperate parts of the country, and largely between 1890 and 1950. A new wave of extinctions is now threatening Australian mammals, this time in northern Australia. Many mammal species are in sharp decline across the north, even in extensive natural areas managed primarily for conservation. The main evidence of this decline comes consistently from two contrasting sources: robust scientifi c monitoring programs and more broad-scale Indigenous knowledge. The main drivers of the mammal decline in northern Australia include inappropriate fi re regimes (too much fi re) and predation by feral cats. Cane Toads are also implicated, particularly to the recent catastrophic decline of the Northern Quoll. Furthermore, some impacts are due to vegetation changes associated with the pastoral industry. Disease could also be a factor, but to date there is little evidence for or against it. Based on current trends, many native mammals will become extinct in northern Australia in the next 10-20 years, and even the largest and most iconic national parks in northern Australia will lose native mammal species. This problem needs to be solved. The fi rst step towards a solution is to recognise the problem, and this publication seeks to alert the Australian community and decision makers to this urgent issue.

  • Season of the Marsupial Bandicoot, Isoodon Macrourus R
    Influence of melatonin on the initiation of the breeding season of the marsupial bandicoot, Isoodon macrourus R. T. Gemmell Department of Anatomy, University of Queensland, St Lucia, Brisbane, Queensland 4067, Australia Summary. Melatonin implants were administered to 6 female bandicoots during the months of May and July. These animals, together with 6 control bandicoots were housed in large outside enclosures with mature males. Births were observed in the 6 control animals from 26 July to 2 September, but no births were observed in the 6 bandicoots with melatonin implants. These results would suggest that photoperiod, which is known to influence melatonin concentrations, may be a factor in the initiation of births in the bandicoot. However, the gradual build-up of births would suggest that other factors such as temperature and rainfall may also have some influence. Introduction The bandicoots which reside along the Eastern Australian coast are all seasonally breeding marsupials, most of the births occurring in the spring and summer months (Heinsohn, 1966; Gordon, 1971; Stoddart & Braithwaite, 1979; Gemmell, 1982; Barnes & Gemmell, 1984). The cycle of breeding activity is more pronounced as the latitude increases. In Tasmania, Victoria and New South Wales definite periods of non-breeding or anoestrus were observed, but in Queensland lactating northern brown bandicoots (Isoodon macrourus) were observed throughout the year (Hall, 1983), although there was a decrease in breeding during the months April to June (Gemmell, 1982, 1986b). This reduction in the degree of seasonality of reproduction in the bandicoot as the latitude decreases would indicate that the bandicoot is exhibiting a 'high degree of flexibility and opportunism associated with the breeding of most small mammals' (Bronson, 1985).

High quality habitat at release sites is known to improve the success of assisted colonisations, but defining high quality habitat can be challenging when species no longer inhabit their historical range. A partial solution to this problem is to quantify habitat use at release sites, and use results to inform assisted colonisation in the future. In this study, we quanti- fied habitat use by the eastern barred bandicoot Perameles gunnii, functionally extinct on the Australian mainland, immediately after translocation to an island ecosystem.

  • Northen Brown Bandicoots in the NT Receive a Helping Hand Sophie
    Northern brown bandicoots in the Northern Territory recieve a helping hand ! By Sophie Moles Recent research has created useful diagnostic resources to evaluate the health of wild northern brown bandicoots in the Top End, NT. The northern brown bandicoot is a native terrestrial marsupial found in the northern and eastern parts of Australia, including New Guinea. The northern brown bandicoot is considered one of the most common bandicoot species, however in recent years has faced threats including predation and fire within the Northern Territory (NT), the geographic focus of this study. Given the significant declines of other marsupials within the NT, such as the Northern Quoll, pre-emptive strategies like the consolidation of health data for the northern brown bandicoot should aid the management of this species. This study used blood, collected in previous fieldwork, from 81 wild northern brown bandicoots in the Top End of the NT to create reference intervals (RI) which are a range of normal values which blood results are compared against to indicate health status, with values outside RI suggestive of ill-health. As previously no RI existed for wild northern brown bandicoots within the Top End, and although RI were established for other bandicoot species, species-specific RI are a more accurate tool to detect disease. This study reported RI, the 2.5th and 97.5th percentile, as well as summary statistics for the entire cohort, and for male and female northern brown bandicoots, as seven blood components were identified as significantly different between the sexes. As for RI, no morphological description of white blood cells existed for this species.

  • Thylacomyidae
    FAUNA of AUSTRALIA 25. THYLACOMYIDAE KEN A. JOHNSON 1 Bilby–Macrotis lagotis [F. Knight/ANPWS] 25. THYLACOMYIDAE DEFINITION AND GENERAL DESCRIPTION The family Thylacomyidae is a distinctive member of the bandicoot superfamily Perameloidea and is represented by two species, the Greater Bilby, Macrotis lagotis, and the Lesser Bilby, M. leucura. The Greater Bilby is separated from the Lesser Bilby by its greater size: head and body length 290–550 mm versus 200–270 mm; tail 200–290 mm versus 120–170 mm; and weight 600–2500 g versus 311–435 g respectively (see Table 25.1). The dorsal pelage of the Greater Bilby is blue-grey with two variably developed fawn hip stripes. The tail is black around the full circumference of the proximal third, contrasting conspicuously with the pure white distal portion, which has an increasingly long dorsal crest. The Lesser Bilby displays a delicate greyish tan above, described by Spencer (1896c) as fawn-grey and lacks the pure black proximal portion in the tail. Rather, as its specific name implies, the tail is white throughout, although a narrow band of slate to black hairs is present on the proximal third of the length. Finlayson (1935a) noted that the Greater Bilby lacks the strong smell of the Lesser Bilby. The skull of the Lesser Bilby is distinguished from the Greater Bilby by its smaller size (basal length 60-66 mm versus 73–104 mm; [Troughton 1932; Finlayson 1935a]), the more inflated and smoother tympanic bullae (Spencer 1896c), the absence of a fused sagittal crest in old males and the distinctly more cuspidate character in the crowns in the unworn molars (Finlayson 1935a).

Their habitat, distribution, abundance and economic significance varies in different crops, seasons and geographical regions of the country. Of these, Bandicota bengalensis is the most predominant and widespread pest of agriculture in wet and irrigated soils and has also established in houses and godowns in metropolitan cities like Bombay, Delhi and Calcutta. In dryland agriculture Tatera indica and Meriones hurrianae are the predominant rodent pests. Some species like Rattus meltada, Mus musculus and M. booduga occur in both wet and dry lands. Species like R. nitidus in north-eastern hill region and Gerbillus gleadowi in the Indian desert are important locally. The common commensal pests are Rattus rattus and M. musculus throughout the country including the islands. R. rattus along with squirrels Funambulus palmarum and F. tristriatus are serious pests of plantation crops such as coconut and oil palm in the southern peninsula. F. pennanti is abundant in orchards and gardens in the north and central plains and sub-mountain regions.
