The research purpose is to investigate the characteristics of bandicoot’s (Echymipera kalubu) carcass in the Manokwari Regency, West Papua Province. Thirty-two (32) bandicoots, with the age of ± 4-month-old, were used for this study, the subjects consisted of 16 males and 16 females. The research method used was the exploration method. The results showed that the bodyweight of males and females bandicoot was 1709.38 ± 506.31 g and 976.63 ± 296.11 g (P<0.05). Carcass weight of males and females bandicoot was 1339 ± 449.53 g and 738.22 ± 233.50 g (P<0.05) respectively. Carcass percentage of males and females bandicoot was 77.15 ± 6.24 % and 75.10 ± 4.32 % (P>0.05). The weight cut forequarter of males and females bandicoot was 614.85±221.87 g and 311.67±101.83 g (P<0,05). The weight cut of the hindquarter of males and females bandicoot was 768.76±377.66 g and 397.89±142.18 g (P<0,05). Fore carcass percentages of males and females bandicoot were 45.48±2.20 % and 42.39±3.50 % (P<0,05). Hind carcass percentage of males and females bandicoot was 56.22±12.22 % and 53.63±6.82% (P>0,05). In conclusion, there are differences in body weight, carcass weight, fore carcass weight, rear carcass weight, and the percentage of fore carcass weight between male and female Echymipera kalubu. On the other hand, there is no difference in the percentage of carcass and rear carcass percentage between male and female Echymipera kalubu.

Full textAbstract:
The habitat requirements of the eastern barred bandicoot, Perameles gunnii, in Tasmania were investigated with road-kill survey data and by mapping habitat features along survey routes. Road-kills of eastern barred bandicoots were most numerous in the South-east and North-west, less common in the North-east and Midlands, and very uncommon on the East Coast. Logistic regression of bandicoot presencelabsence data suggested that traffic volume is the major determinant of the road-kill distribution of eastern barred bandicoots around Tasmania. Along with traffic volume, rainfall was found to be strongly associated with the presence of eastern barred bandicoot road-kills for the state combined and for the South-east and Northeast, while along the Huon Highway in the South-east, soil depth was associated with the presence of roadkills. Favoured habitat of the eastem barred bandicoot is high-quality agricultural land with deep soils and high rainfall. It is hypothesised that clearing for agriculture in south-eastem, north-eastem and north-westem Tasmania has opened up previously unsuitable, heavily forested habitat for colonisation by eastern barred bandicoots. The resulting mosaic of pasture and remnant bush appears to provide ideal habitat for the eastern barred bandicoot. However, the majority of bandicoot habitat is found on private land, making the species vulnerable to changes in farming practices. Possible management options are briefly discussed.

Full textAbstract:
Bandicoots in the family Peroryctidae in New Guinea are widespread and relatively abundant, but little is known of their ecology. We present the first detailed study on the ecology of the kalubu bandicoot (Echymipera kalubu) and observations on Raffray’s bandicoot (Peroryctes raffrayanus), from mid-montane forest in Papua New Guinea. Both species were primarily nocturnal and utilised a range of habitats including those modified by human activity, although Raffray’s bandicoot was more frequently encountered in less disturbed areas. Male kalubu bandicoots were larger than females, with larger animals having larger short-term home ranges and evidence for intrasexual territoriality. Mean short-term home-range size was 2.8 ha (MCP, n = 10), with an estimated population density of ~85 animals km–2 in the study area. Female kalubu bandicoots attained sexual maturity at ~400 g and 67% of mature females were reproductively active with an average of 1.5 young per litter. Both species were hunted, but their density, rate of reproduction and use of modified habitats suggest that they were able to withstand current hunting levels.

The Barrow I. golden bandicoot (Isoodon auratus) is a small arid-adapted marsupial. It has a low and labile body temperature, a low basal metabolic rate, a low thermal conductance, and a low rate of evaporative water loss. Its metabolic, thermal and hygric physiology resembles that of another arid-adapted bandicoot, the bilby, and differs from temperate and tropical bandicoots.

Full textAbstract:
Mammals that forage for food by biopedturbation can alter the biotic and abiotic characteristics of their habitat, influencing ecosystem structure and function. Bandicoots, bilbies, bettongs and potoroos are the primary digging marsupials in Australia, although most of these species have declined throughout their range. This study used a snapshot approach to estimate the soil turnover capacity of the southern brown bandicoot (Isoodon obesulus, Shaw 1797), a persisting digging Australian marsupial, at Yalgorup National Park, Western Australia. The number of southern brown bandicoots was estimated using mark–recapture techniques. To provide an index of digging activity per animal, we quantified the number of new foraging pits and bandicoot nose pokes across 18 plots within the same area. The amount of soil displaced and physical structure of foraging pits were examined from moulds of 47 fresh foraging pits. We estimated that an individual southern brown bandicoot could create ~45 foraging pits per day, displacing ~10.74 kg of soil, which extrapolates to ~3.9 tonnes of soil each year. The digging activities of the southern brown bandicoots are likely to be a critical component of soil ecosystem processes.

Abstract
Bandicoot (Echypera rufescens) is an alternative source of animal protein and a source of germplasm for humans, especially local communities in Papua. These animals are obtained by hunting and/or setting traps in the community's closest habitat. The aim of this research was to determine the relationship between body measurements and body weight and carcass weight by utilizing 32 bandicoots, 16 males and 16 females, with a live weight range of 400 - 2000 grams in Yapen Island Regency, Papua. The study was conducted by using an explorative study and the data were analyzed using multiple correlations and regression. The carcass was obtained by slaughtering the head, removing the blood, and then removing the hair by burning (singeing). The average body weight of male bandicoots was 1403 grams and that of females was 598.75 grams, while the average carcass weights of males and females were 1050.06 grams and 415 grams, respectively. The average heart girth of male bandicoots is 23.03 cm and that of females is 17.81 cm, while the average body length of male and female bandicoots is 25.19 cm and 18.91 cm, respectively. The average percentage of male bandicoot carcasses was 73.99 cm and that of females was 69.22 cm. The correlation coefficient between body weight and body measurements was 0.911 while the carcass weight and body measurements were 0.901. The correlation between body weight and carcass of male bandicoots were 0.911 and 0.901. The correlation between body weight and carcass of female bandicoot were 0.702 and 0.747. The regression equation for male bandicoots to estimate body weight (BB) and carcass weight (BK) were BB = (-1705, 594+84,432 X1 +46,234X2) and (BK = -432,092 +71,545 X1 +33,127X2). The female bandicoot regression equations to estimate body weight (BB) and carcass weight (BK) were: (BB = -509,134+39,437 X1 +21,443X2) and (BK= -436,703 +31,720 X1 +15,164X2).

Full textAbstract:
Context Assisted colonisation has the potential to protect species from intractable threats within their historical ranges. The Australian mainland subspecies of the eastern barred bandicoot (Perameles gunnii) is extinct in the wild, with surviving populations restricted to small sites protected by predator–barrier fences. PVA modelling shows that a self-sustaining bandicoot population would require an area free of the introduced red fox (Vulpes vulpes) of at least 2500ha. French Island is outside the historic range of the species, but is fox-free and contains around 9000ha of potentially suitable habitat. Aims This study will assess the suitability of French Island as a potential site for a self-sustaining eastern barred bandicoot population by conducting a 1-year assisted colonisation trial to assess habitat use, body condition and survival. Methods Between July and September 2012, 18 adult bandicoots were released. We radio-tracked bandicoots using intraperitoneal radio-transmitters for up to 122 days and trapped fortnightly. Key results The release group met the three measures of success: (1) appropriate habitat use; (2) recovery of post-release bodyweight; and (3) founder survival exceeding 100 days. Habitat use and body condition throughout the trial reflected that of mainland populations, and seven bandicoots survived longer than 100 days. Mortality was greatest in the first month, with veterinary investigations confirming two deaths due to cat predation, two deaths from toxoplasmosis and one unknown cause of death. Bandicoots that survived longer than 100 days occupied higher, drier ground than those that did not. Toxoplasmosis cases were associated with lower topographic position on the site. Conclusions Our results suggest that French Island provides suitable habitat for the establishment of a population of eastern barred bandicoots. On French Island, toxoplasmosis was identified as an important source of mortality in addition to cat predation, and warrants further investigation. Implications Given the costs and challenges of predator control and the maintenance of predator exclusion fences, assisted colonisation to one or more fox-free islands remains the most viable option to establish self-sustaining bandicoot populations. Our results highlight the value in conducting trial releases ahead of major translocations.

Full textAbstract:
Infrared digital cameras were used to examine temporal detection rates of medium-sized ground-dwelling mammals in a coastal woodland landscape. From three successive deployments at fixed stations, a range of mammals was detected, including three target species: the long-nosed bandicoot, the long-nosed potoroo and the southern brown bandicoot. Reporting rates of target species were largely consistent and in some cases high. The swamp wallaby was the most commonly detected species, ranging from 47–67% of cameras on any given deployment. Long-nosed bandicoots were detected at 37–53% of cameras, long-nosed potoroos 13–23% and southern brown bandicoots 10–17%. In total, bandicoots and potoroos were detected at 23 of 30 sites (77%) while forage-diggings of these mammals were universally present. There were differences in the detection rate of bandicoots and potoroos in relation to 24-hourly cycles: all three species were less likely to be detected between dawn and dusk than dusk and dawn. Otherwise, with few exceptions, the rate at which bandicoots and potoroos were detected over time within a deployment did not vary markedly. Infrared digital cameras offer great potential as sampling devices for bandicoots and potoroos because of their greater detection efficiency relative to other techniques.

Full textAbstract:
Roads may create filters or barriers to animal movement and adversely affect population processes. Underpasses are now commonly installed during highway construction to mitigate barrier effects and link habitat patches. We used sand-tracking to investigate use of six underpasses by bandicoots along a section of the Pacific Highway in northern New South Wales before, during and after road duplication (i.e. expansion from two to four lanes). Trapping revealed that the northern brown bandicoot (Isoodon macrourus) and the long-nosed bandicoot (Perameles nasuta) were equally abundant prior to highway expansion. Five years before highway widening, bandicoots frequently used 18-m-long underpasses (>1 traverses per day). Twelve months before road widening, underpass use by bandicoots declined to ~0.5 traverses per day and continued near this level during construction. This declined to 0.03 traverses per day after duplication with underpasses extended to ≥49 m in length. Few crossings were recorded after expansion of the road corridor, which may indicate a shift from regular foraging traverses before duplication to infrequent dispersal movements after duplication.

Full textAbstract:
Almost half of the world's mammal extinctions in the last two hundred years have occurred in Australia (Short and Smith 1994). The western barred bandicoot Perameles bougainville is one of a suite of species that is currently threatened with extinction, surviving only on two islands in Shark Bay, Western Australia. Reintroduction has been used as a tool in conservation biology to assist in the recovery of threatened species, such as the western barred bandicoot. The aims of this project were to 1) successfully reintroduce and establish a free-ranging mainland population of the western barred bandicoot at Heirisson Prong, Shark Bay, 2) contribute information on the biology of the species, its interactions with introduced species, and its likelihood of persistence as a reintroduced population in the longer-term, and 3) to provide recommendations to assist future reintroductions of the species. The first reintroduction of the western barred bandicoot from surviving remnant island populations to the mainland, some 60 years after its apparent mainland extinction, was from Dorre Island to Heirisson Prong in 1995. Animals were translocated initially to a predator-free refuge on Heirisson Prong, and then subsequently released to the 12 km2 peninsula where introduced predators (foxes Vulpes vulpes and feral cats Felis catus) had been controlled, but European rabbits Oryctolagus cuniculus had not. Despite a small founder number and high mortality of free-range bandicoots in the presence of a low-density feral cat population, the bandicoot population successfully established. The reintroduced population of western barred bandicoots provided an opportunity to study the biology of the species, and to compare it with the remnant island populations and other species of Australian bandicoot. Many population parameters were similar between the island and mainland western barred bandicoot populations, as well as between the western barred bandicoot and other bandicoot species, suggesting that the habitat at the reintroduction site is suitable for long-term persistence of the population. However, there were some notable differences. The western barred bandicoot is the smallest extant species of bandicoot, with fewer young per litter than recorded for other bandicoot species, adult sex ratios were closer to parity, animals reached sexual maturity later, and it is the only species of bandicoot where females are larger than males. Home range size is larger also than recorded for other species. Some of these differences may be explained in part by trade-offs between island dwarfism, lactational pressures, and nest defence. The nesting biology of the western barred bandicoot was studied at Heirisson Prong, including during periods of high and low densities of rabbits. Individuals of the species constructed and utilised nests in a similar fashion to other species of Australian bandicoot, nesting amongst litter underneath shrubs. The western barred bandicoot appeared to favour particular shrub species, especially when vegetation condition was poor due to rabbit damage, but displayed flexibility in being able to construct nests under a variety of shrub species where at least some surface litter was present. Grasses were used in nest construction only when rabbit density was low. Nests appear important for protection against temperature extremes and diurnal predators. Vegetation exclosures around three of the shrub species most commonly used by the western barred bandicoot for nest sites (Acacia ligulata, A. tetragonophylla and Melaleuca cardiophylla) were used to examine the impact of rabbits on vegetation on Heirisson Prong. A high-density rabbit population over the summer of 1997/98 caused in a decrease in canopy cover and the death of mature A. ligulata. Subsequent rainfall and low-density rabbit populations allowed A. tetragonophylla shrubs to recover their former structure, and M. cardiophylla to recover, but not to the same degree. The flexibility of western barred bandicoots in use of nest materials and their omnivorous diet may enable the species to survive in the face of habitat modification by rabbits. Population viability analysis was used to examine future options for the recovery of the endangered western barred bandicoot. Biological data from the Dorre Island and Heirisson Prong populations were input to the computer simulation program VORTEX. The western barred bandicoot populations were modelled under a variety of scenarios to examine the possible effects of changes in carrying capacity, founder population size, inbreeding depression, and the occurrence of drought and cat predation as catastrophes, on the probability of population extinction. This analysis highlighted the need for eradication of feral cats, above all other management actions. Cat predation was particularly potent when it acted through high loss of juveniles, as well as adult bandicoots. Predator control is considered critical for the long-term persistence of reintroduced populations of the western barred bandicoot. This study documents the first reintroduction of the endangered western barred bandicoot to mainland Australia. The population had been extant for four years at the completion of data collection for this thesis, in late 1999 and for over eight years at the finalisation of this thesis in July 2004. The knowledge gained from the reintroduction was used to discuss management recommendations and future options for the recovery of the species. The primary concern for reintroductions of this, and other species of bandicoots, remains the control of introduced predators. For long-term persistence of small, isolated populations, such as those of the western barred bandicoot at Heirisson Prong and the Arid Recovery Project at Roxby Downs in South Australia, and the eastern barred bandicoot Perameles gunnii at a range of sites in Victoria, the complete eradication of introduced predators is essential.

Conservation efforts to prevent the extinction of the endangered western barred bandicoot Perameles bougainville (WBB) are currently hindered by a debilitating progressive papillomatosis and carcinomatosis syndrome. Now extinct on mainland Australia, wild populations of the WBB are known only to exist on Bernier and Dorre Islands in Shark Bay, Western Australia. This thesis describes and analyses the pathological (gross, histological, ultrastructural) and immunohistochemical features of a papillomatosis and carcinomatosis syndrome in the WBB. The detection and characterisation of a novel virus, the bandicoot papillomatosis carcinomatosis virus type 1 (BPCV1), found in association with cutaneous and muco-cutaneous papillomas and carcinomas, is described. BPCV1 was found to exhibit genomic and morphological features of both the Papillomaviridae and the Polyomaviridae, and may represent the first member of a new family of viruses. The findings of this study provide evidence that BPCV1 is the causative agent of the papillomatosis and carcinomatosis syndrome. Clinical, pathological and molecular evidence of the syndrome and BPCV1 were found in the Bernier Island WBB population at Red Cliff and in captive populations comprising all or a proportion of founder WBBs from this site, but not at all in the WBB population on Dorre Island or Heirisson Prong. The papillomatosis and carcinomatosis syndrome in the western barred bandicoot is a pertinent example of a disease process hampering efforts to prevent the extinction of an endangered species.

Reintroduction has been used as a tool in conservation biology to assist in the recovery of threatened species, such as the western barred bandicoot. The aims of this project were to 1) successfully reintroduce and establish a free-ranging mainland population of the western barred bandicoot at Heirisson Prong, Shark Bay, 2) contribute information on the biology of the species, its interactions with introduced species, and its likelihood of persistence as a reintroduced population in the longer-term, and 3) to provide recommendations to assist future reintroductions of the species. The first reintroduction of the western barred bandicoot from surviving remnant island populations to the mainland, some 60 years after its apparent mainland extinction, was from Dorre Island to Heirisson Prong in 1995. Animals were translocated initially to a predator-free refuge on Heirisson Prong, and then subsequently released to the 12 km2 peninsula where introduced predators (foxes Vulpes vulpes and feral cats Felis catus) had been controlled, but European rabbits Oryctolagus cuniculus had not. Despite a small founder number and high mortality of free-range bandicoots in the presence of a low-density feral cat population, the bandicoot population successfully established. The reintroduced population of western barred bandicoots provided an opportunity to study the biology of the species, and to compare it with the remnant island populations and other species of Australian bandicoot. Many population parameters were similar between the island and mainland western barred bandicoot populations, as well as between the western barred bandicoot and other bandicoot species, suggesting that the habitat at the reintroduction site is suitable for long-term persistence of the population. However, there were some notable differences. The western barred bandicoot is the smallest extant species of bandicoot, with fewer young per litter than recorded for other bandicoot species, adult sex ratios were closer to parity, animals reached sexual maturity later, and it is the only species of bandicoot where females are larger than males. Home range size is larger also than recorded for other species. Some of these differences may be explained in part by trade-offs between island dwarfism, lactational pressures, and nest defence. The nesting biology of the western barred bandicoot was studied at Heirisson Prong, including during periods of high and low densities of rabbits. Individuals of the species constructed and utilised nests in a similar fashion to other species of Australian bandicoot, nesting amongst litter underneath shrubs. The western barred bandicoot appeared to favour particular shrub species, especially when vegetation condition was poor due to rabbit damage, but displayed flexibility in being able to construct nests under a variety of shrub species where at least some surface litter was present. Grasses were used in nest construction only when rabbit density was low. Nests appear important for protection against temperature extremes and diurnal predators. Vegetation exclosures around three of the shrub species most commonly used by the western barred bandicoot for nest sites (Acacia ligulata, A. tetragonophylla and Melaleuca cardiophylla) were used to examine the impact of rabbits on vegetation on Heirisson Prong. A high-density rabbit population over the summer of 1997/98 caused in a decrease in canopy cover and the death of mature A. ligulata. Subsequent rainfall and low-density rabbit populations allowed A. tetragonophylla shrubs to recover their former structure, and M. cardiophylla to recover, but not to the same degree. The flexibility of western barred bandicoots in use of nest materials and their omnivorous diet may enable the species to survive in the face of habitat modification by rabbits. Population viability analysis was used to examine future options for the recovery of the endangered western barred bandicoot. Biological data from the Dorre Island and Heirisson Prong populations were input to the computer simulation program VORTEX. The western barred bandicoot populations were modelled under a variety of scenarios to examine the possible effects of changes in carrying capacity, founder population size, inbreeding depression, and the occurrence of drought and cat predation as catastrophes, on the probability of population extinction. This analysis highlighted the need for eradication of feral cats, above all other management actions. Cat predation was particularly potent when it acted through high loss of juveniles, as well as adult bandicoots. Predator control is considered critical for the long-term persistence of reintroduced populations of the western barred bandicoot. This study documents the first reintroduction of the endangered western barred bandicoot to mainland Australia. The population had been extant for four years at the completion of data collection for this thesis, in late 1999 and for over eight years at the finalisation of this thesis in July 2004. The knowledge gained from the reintroduction was used to discuss management recommendations and future options for the recovery of the species. The primary concern for reintroductions of this, and other species of bandicoots, remains the control of introduced predators. For long-term persistence of small, isolated populations, such as those of the western barred bandicoot at Heirisson Prong and the Arid Recovery Project at Roxby Downs in South Australia, and the eastern barred bandicoot Perameles gunnii at a range of sites in Victoria, the complete eradication of introduced predators is essential.

This thesis investigates the process of habitat fragmentation and the spatial and temporal scales at which it occurs. Fragmentation has become an important topic in biogeography and conservation biology because of the impacts it has upon species??? distributions and biodiversity. Various definitions of fragmentation are available but in this research it is considered to be the disruption of continuity, either natural or human-induced in its origins and operative at multiple spatial scales. Using the distribution of the southern brown bandicoot Isoodon obesulus as a case study, three spatial scales of fragmentation were analysed. At the continental scale, the Australian distribution of the subspecies I. o. obesulus was examined in relation to climate, geology and vegetation cover at the time of European settlement of Australia and two centuries later. Using archived wildlife records and Geographic Information Systems (GIS) analyses, habitat suitability models were created to assess natural and human-induced fragmentation of the distribution of I. obesulus in 1788 and 1988. At the regional scale, a study was made of the distribution of I. obesulus in the south-east of the State of South Australia. Again, natural and human-induced patterns of habitat fragmentation were modelled using GIS with climate, soil and vegetation data for the time of European settlement and at present. At the local scale, the distribution of I. obesulus was the subject of a detailed field survey of 372 sites within 29 remnant patches of native vegetation in south-eastern South Australia in order to understand the variables that cause habitat fragmentation. Geographic information systems were used again but in a different way to carefully stratify the field survey by overlaying maps of topography, vegetation and past fires. The large dataset collected from the surveys was described using six generalized linear models which identified the significant variables that fragment the distribution of I. obesulus at a local scale. From the results of the field surveys, a subset of four remnants was chosen for further GIS spatial modelling of the probability of I. obesulus occurring within remnants in response to fire via a controlled burning programme put in place to reduce accumulating fuel loads. These investigations show that habitat fragmentation can be caused by different factors at different spatial scales. At the continental scale, it was found that climate played a dominant role in influencing the fragmented distribution of I. obesulus but vegetation change during the past two centuries has also had a profound impact on the availability of habitat. Within south-eastern South Australia, the species??? regional scale distribution is constrained by climate and also by soil and vegetation patterns. Dramatic change to its regional distribution occurred in the 20th century as a result of the clearance of native vegetation for planting pastures, crops and pines. Fragmentation at the regional scale has resulted in the remaining habitat being reduced to small, isolated, remnant patches of native vegetation. At the local scale it was found that variables which disrupt the continuity of I. obesulus habitat within remnants include vegetation cover in the 0-1 m stratum, abundance of Xanthorrhoea australis and soil texture. For a subset of sites located in one landsystem of the study area, named Young, the age of vegetation since it was last burnt was also found to be a significant variable, with vegetation 10-14 years old since burning providing the most suitable habitat. Spatial modelling of two scenarios for prescribed burning over 15 years revealed that the use of fire as a habitat enhancement tool will be complicated and require a detailed understanding of the factors that cause natural fragmentation in the distribution of I. obesulus at the local scale. A further conclusion of the study was that ecological relationships between species and their habitats require careful interpretation of multi-scaled datasets and conservation plans for endangered species ought to be made at multiple spatial scales. Future research directions are identified including the linking of multi-scaled habitat fragmentation models to genetic studies of the species throughout its range.

Full textAbstract:
One of the few commonly occuring species of digging marsupial in south-western Australia is the subspecies of southern brown bandicoot (Isoodon obesulus fusciventor). Unlike a large proportion of Australian digging marsupials that have suffered attrition, bandicoots have persisted and shown resilience to human-mediated disturbance in peri-urban regions. This thesis evaluates some of the ecological roles of bandicoots in ecosystem processes in degraded Eucalyptus gomphocephala woodland in Yalgorup National Park.
Bandicoots forage for the fruiting bodies of mycorrhizal fungi and other subterranean food and in doing so make small pits in the soil surface. Surveys of these foraging pits over a six month period revealed they are sites of lower soil hydrophobicity and higher soil moisture compared to the surrounding undisturbed soil. Additionally, the foraging pits and the area immediately surrounding them collect more leaf litter than the surrounding areas.
The impact of foraging pits on ant-seed removal rates was explored by creating artificial diggings. Three local seed species Acacia saligna, Eucalyptus gomphocephala, and Kennedia prostrata were used in a cafeteria style experiment. Results found artificially created diggings had no effect on seed removal rates and that E. gomphocephala had the highest seed removal rate.
This study suggests that bandicoots provide an important source of soil surface heterogeneity, contributing to ecosystem processes. Their presence in the landscape has the potential to contribute to the restoration of degraded ecosystems.

For more than a decade, community groups, scientific organizations and government agencies have collaborated to repopulate the endangered western barred bandicoot (Perameles bougainville). While initially successful, the unexpected discovery of a papillomatosis and carcinomatosis syndrome in captive and wild populations of P. bougainville exposed a dearth of knowledge regarding their diseases. This dissertation addresses this issue through study of the clinical pathology, immunology, parasitology, and virology of P. bougainville.
To facilitate the detection and understanding of diseases in P. bougainville, guidelines for interpreting haematology and clinical chemistry results were developed, including calculated species-specific reference intervals for plasma aspartate transaminase activity (20283 U/L), haemoglobin (122-165 g/L), haematocrit (0.36-0.49 L/L), total leukocytes (2.9-14.9 x10^9/L), monocytes (0-0.6 x10^9/L), eosinophils (0-0.9 x10^9/L) and total protein (47-63 g/L) estimated by refractometry. P. bougainville immunoglobulin was also fractionated from plasma and inoculated into sheep to derive antiserum for serological screening assays.
Arthropods, helminths and protozoa parasitic on P. bougainville were catalogued and Eimeria kanyana n. sp. was formally described. The pathogenic and zoonotic potential of bacteria detected in ticks parasitic on P. bougainville was also considered.
The association between bandicoot papillomatosis carcinomatosis virus type 1 (BPCV1) and the western barred bandicoot papillomatosis and carcinomatosis syndrome was investigated using PCR, in situ hybridization and virus isolation. Optimized in situ hybridization techniques demonstrated BPCV1 DNA within keratinocyte and sebocyte nuclei, and BPCV1 mRNA within the cytoplasm. BPCV1 virions were isolated by ultracentrifugation and visualized with negative stain transmission electron microscopy revealing icosahedral, non-enveloped viral capsids ~47 nm in diameter, comparable to viruses classified within Papillomaviridae and Polyomaviridae.
A novel virus, tentatively named bandicoot papillomatosis carcinomatosis virus type 2 (BPCV2) was discovered in papillomatous lesions from a southern brown bandicoot (Isoodon obesulus). It had a circular double-stranded DNA genome of 7277 bp, and encoded two papillomavirus-like structural proteins, L1 and L2, and two polyomavirus-like putative transforming proteins, large T antigen and small t antigen. DNA and RNA in situ hybridization confirmed the presence of BPCV2 nucleic acids within lesion biopsies. The discovery of the bandicoot papillomatosis carcinomatosis viruses has provoked reassessment of the established virus taxonomy paradigm, theories of virus-host co-speciation and bandicoot population management strategies.

Full textAbstract:
There are about 265 living species of marsupial mammals, the majority in Australasia, about 60 in South America, and a handful in Central and North America (Macdonald 2001). They are distinguishable from the placental mammals by many characters, but most profoundly by their mode of reproduction. Compared to the placentals, there is only a relatively brief intrauterine period, during which the embryo exchanges nutrients and gases with the mother via a simple, non-invasive yolk sac placenta. There is no development of the complex, highly invasive chorio-allantoic placenta found in the placentals with the partial exception of the bandicoots in which there is a small, short-lived, but true chorio-allantoic placenta. The marsupial neonate is born at a very immature stage, and most of the total maternal provision comes via lactation. In the majority of cases the young are carried in a pouch, although there are exceptions to this. Whether pouched or not, the young attach themselves continuously to the teat for an extended period of time. There has been much discussion about whether the marsupial mode of reproduction is ancestral to that of the placental mammals, or whether it represents an independent, parallel acquisition of viviparity. Lillegraven (1979), Lillegraven et al. (1987), and Szalay (1994), for example, regarded the marsupial mode as primitive and inefficient compared to the placental mode, and that it was failure of the marsupials to evolve a mechanism to prevent immunological rejection of the embryo by the mother that prevented any extension of the gestation period. Placentals, they argued, solved the problem by evolving the trophoblast layer of embryonic cells that performs the function of preventing the maternal antibodies from damaging the embryo. Conversely, several authors such as Parker (1977) have argued that the marsupial mode is an alternative, but equally well-adapted strategy of reproduction to that of placentals. It is one of low investment but low risk, and is therefore suitable for a more unpredictable environment. Tyndale-Biscoe and Renfree (1987) suggested that primitive marsupials and placentals had quite similar reproduction, with relatively immature neonates and a relatively long lactation period. Subsequent specialisation in the two groups went in different directions.

ABSTRACT Soccer set pieces are a crucial part of the game. Research on goal effectiveness from major championships is important and can lead to change and evolutionary trends in football. The aim of this study was to analyze the goals scored through set pieces during the 2020 UEFA Euro 2020. It was analyzed 51 matches with a record 142 goals at an average of just shy of three per game. 40 goals scored of the total are from set pieces. 17 from a corner, 11 from a penalty, 8 goals following a free kick, 3 goals following a throw-in, and just one goal from a direct free kick. For data processing we used modern software products - Bandicut is the fastest and without loss of quality software for cutting and merging video and Wy-scout - The professional platform for people working in the football world: videos, data, statistics, and tools. The data obtained from the present study were processed through mathematical and statistical methods. The analysis shows that set pieces can be an important means of determining victory in high-level football matches, especially between teams of the same level.
