Abstract:
In the early 1980s advances in marsupial biology could no longer be encapsulated in a single volume such as Hugh Tyndale-Biscoe's "Life of Marsupials" and Cambridge University Press commissioned a series of monographs covering a range of different topics in marsupial biology. As it was, only three of that series were realized and among them was the ptedecessor to this book "Digestive Physiology and Nutrition of Marsupials" published in 1982. "Marsupial Nutrition" is a considerably expanded and comprehensive review of studies of nutrition and digestive physiology of Australasian and South American marsupials. In Australia, many ecologists view the limited nutrient status of our soils and vegetation as a fundamental limit to animal populations. This book explains firstly how Australian marsupials have responded to those limitations and secondly asks whether these responses are common amongst marsupials living in New Guinea and South America.

Abstract:
ABSTRACT We analyzed the presence of Leptospira spp. in liver and kidney tissue of wild marsupials and rodents trapped in a periurban forest in the eastern Brazilian Amazon. We examined 25 individuals of four marsupial and seven rodent species for the presence of the 16S rRNA gene of Leptospira in the DNA extracted from 47 liver and kidney tissue samples using PCR. We detected positive samples in 12% (3/25) of the individuals, in kidney fragments of two marsupial species (Didelphis marsupialis and Marmosops pinheiroi) and in a liver fragment of one rodent species (Echimys chrysurus). These are the first records of Leptospira spp. in M. pinheiroi and E. chrysurus and it is the first molecular survey of marsupials and rodents in the Brazilian Amazon.

Abstract:
Little is known of the non-dinosaurian fauna from the Cretaceous (Maastrichtian) part of the North Horn Formation, despite its biogeographic importance. Herein we describe a new marsupial mammal from the unit, founded on an exceptionally complete specimen of a juvenile individual, and present new information on the incisor region of early marsupials, based on comparison with complete specimens from the early Paleocene of Bolivia. Alphadon eatoni, new species, is the smallest Lancian species of the genus, and departs from a presumed marsupial morphotype in having the second lower incisor enlarged. The species is, however, primitive in lacking a “staggered” pattern to the incisor series and in having a labial mandibular foramen, and in these respects it differs from Paleocene and later marsupials. Poor representation of other taxa precludes meaningful comparison to most other North American Cretaceous marsupials, although Eodelphis, thought to be distantly related, also has an enlarged i2. Although Alphadon is characterized by many primitive features, the relative development of the incisors is not what would be predicted in a morphological antecedent to later Marsupialia.

Abstract:
The musculoskeletal system of marsupial mammals has numerous unusual features beyond the pouch and epipubic bones. One example is the widespread absence or reduction (to a fibrous “patelloid”) of the patella (“kneecap”) sesamoid bone, but prior studies with coarse sampling indicated complex patterns of evolution of this absence or reduction. Here, we conducted an in-depth investigation into the form of the patella of extant marsupial species and used the assembled dataset to reconstruct the likely pattern of evolution of the marsupial patella. Critical assessment of the available literature was followed by examination and imaging of museum specimens, as well as CT scanning and histological examination of dissected wet specimens. Our results, from sampling about 19% of extant marsupial species-level diversity, include new images and descriptions of the fibrocartilaginous patelloid in Thylacinus cynocephalus (the thylacine or “marsupial wolf”) and other marsupials as well as the ossified patella in Notoryctes ‘marsupial moles’, Caenolestes shrew opossums, bandicoots and bilbies. We found novel evidence of an ossified patella in one specimen of Macropus rufogriseus (Bennett’s wallaby), with hints of similar variation in other species. It remains uncertain whether such ossifications are ontogenetic variation, unusual individual variation, pathological or otherwise, but future studies must continue to be conscious of variation in metatherian patellar sesamoid morphology. Our evolutionary reconstructions using our assembled data vary, too, depending on the reconstruction algorithm used. A maximum likelihood algorithm favours ancestral fibrocartilaginous “patelloid” for crown clade Marsupialia and independent origins of ossified patellae in extinct sparassodonts, peramelids, notoryctids and caenolestids. A maximum parsimony algorithm favours ancestral ossified patella for the clade [Marsupialia + sparassodonts] and subsequent reductions into fibrocartilage in didelphids, dasyuromorphs and diprotodonts; but this result changed to agree more with the maximum likelihood results if the character state reconstructions were ordered. Thus, there is substantial homoplasy in marsupial patellae regardless of the evolutionary algorithm adopted. We contend that the most plausible inference, however, is that metatherians independently ossified their patellae at least three times in their evolution. Furthermore, the variability of the patellar state we observed, even within single species (e.g. M. rufogriseus), is fascinating and warrants further investigation, especially as it hints at developmental plasticity that might have been harnessed in marsupial evolution to drive the complex patterns inferred here.

Abstract:
We review past DNA-hybridisation studies of marsupials and present a reanalysis of the data, utilising results from our and additional studies to formulate and rationalise a new classification of Marsupialia. In the reanalysis, 13 individual DNA-hybridisation matrices, many lacking some pairwise comparisons, were sutured in stages to provide the basis for generating a tree of 101 marsupials plus an outgroup eutherian; a fourteenth matrix provided data for a tree including eight additional eutherians and a monotreme. Validation was achieved by jackknifing on taxa for each matrix as well as on tables combining two or more matrices generated during assembly of the 102-taxon data set. The results are consistent with most conclusions from the individual studies and dramatise the unevenness of hierarchical levels in current classifications of marsupials. In particular, the affinities of the American marsupial Dromiciops gliroides with, and the distinctness of marsupial bandicoots from, Australasian metatherians are reaffirmed, while opossums are shown to be as internally divergent as are most members of the order Diprotodontia. Calibration of the 102-taxon tree and dating of the major dichotomies suggest that no extant marsupial lineage originated before the latest Cretaceous, and that all of them together with most South American and all Australasian fossils should be recognised as a monophyletic group contrasting with a largely Laurasian (if possibly paraphyletic) taxon. These inferences, together with the details of the phylogeny, mandate that the misleading ‘Australian’ v. ‘American’ distinction be abandoned, even as a geographic convenience.

Abstract:
Marsupial and eutherian mammals inactivate one X chromosome in female somatic cells in what is thought to be a means of compensating for the unbalanced X chromosome dosage between XX females and XY males. The hypothesis of X chromosome inactivation (XCI) was first published by Mary Lyon just over 50 years ago, with the discovery of XCI in marsupials occurring a decade later. However, we are still piecing together the evolutionary origins of this fascinating epigenetic mechanism. From the very first studies on marsupial X inactivation, it was apparent that, although there were some similarities between marsupial and eutherian XCI, there were also some striking differences. For instance, the paternally derived X was found to be preferentially silenced in marsupials, although the silencing was often incomplete, which was in contrast to the random and more tightly controlled inactivation of the X chromosome in eutherians. Many of these earlier studies used isozymes to study the activity of just a few genes in marsupials. The sequencing of several marsupial genomes and the advent of molecular cytogenetic techniques have facilitated more in-depth studies into marsupial X chromosome inactivation and allowed more detailed comparisons of the features of XCI to be made. Several important findings have come from such comparisons, among which is the absence of the XIST gene in marsupials, a non-coding RNA gene with a critical role in eutherian XCI, and the discovery of the marsupial RSX gene, which appears to perform a similar role to XIST. Here I review the history of marsupial XCI studies, the latest advances that have been made and the impact they have had towards unravelling the evolution of XCI in mammals.

Abstract:
AbstractThe marsupium of the primarily terrestrial isopod sub-order Oniscidea is modified from the basal marine design and represents one of the key evolutionary innovations enabling the invasion of land habitats. In the Ligiidae, the marsupial chamber is provisioned with water from the external environment via a capillary channel formed from the apposed 6th and 7th pereiopods. The other oniscidean families possess a 'closed' marsupium, isolated from the pleural water-conducting system and provisioned with water and ions by sternal cotyledons. How these different modes of fluid provisioning influence the ionic composition of marsupial fluid and its osmotic and ionic relationship to the haemolymph remains essentially unstudied. We analysed the ionic composition (Na+, K+, Ca2+, Cl–, pH) of marsupial fluid and haemolymph in 4 species of Oniscidea: Ligia occidentalis (Ligiidae), Ligidium lapetum (Ligiidae), Alloniscus perconvexus (Alloniscidae), and Armadillidium vulgare (Armadillidiidae). In all four species, ion concentrations show a broad similarity between marsupial fluid and haemolymph, but with elevated potassium concentrations in the 'closed'-marsupium species. The sternal integument of Armadillidium vulgare is permeable to inulin and the volume of the combined marsupial fluid and haemolymph is not significantly enlarged compared to the haemolymph of non-gravid females. Accordingly, the 'closed' marsupium of A. vulgare can be viewed as a functional subdivision of the haemolymph space. In Ligidium lapetum, marsupial water is derived from external freshwater sources, but marsupial fluid [Na+] and [Cl–]are actually significantly higher than haemolymph values. This species thus possesses an effective means of ion provisioning, paralleling that seen in the 'closed' marsupial species.

Marsupial immune responses were previously touted as ‘primitive’ but we now know that the marsupial immune system is complex and on par with that of eutherian mammals. In this manuscript we review the field of marsupial immunology, focusing on basic anatomy, developmental immunology, immunogenetics and evolution. We concentrate on advances to our understanding of marsupial immune gene architecture, made possible by the recent sequencing of the opossum, tammar wallaby and Tasmanian devil genomes. Characterisation of immune gene sequences now paves the way for the development of immunological assays that will allow us to more accurately study health and disease in marsupials.

Abstract:
Seasonal two-way migration is an ecological phenomenon observed in a wide range of large-bodied placental mammals, but is conspicuously absent in all modern marsupials. Most extant marsupials are typically smaller in body size in comparison to their migratory placental cousins, possibly limiting their potential to undertake long-distance seasonal migrations. But what about earlier, now-extinct giant marsupial megafauna? Here we present new geochemical analyses which show that the largest of the extinct marsupial herbivores, the enormous wombat-like Diprotodon optatum , undertook seasonal, two-way latitudinal migration in eastern Sahul (Pleistocene Australia–New Guinea). Our data infer that this giant marsupial had the potential to perform round-trip journeys of as much as 200 km annually, which is reminiscent of modern East African mammal migrations. These findings provide, to our knowledge, the first evidence for repetitive seasonal migration in any metatherian (including marsupials), living or extinct, and point to an ecological phenomenon absent from the continent since the Late Pleistocene.

Full text
Abstract:
Many marsupials produce sex ratios biased towards male or female young. In several cases these changes are comfortably accommodated in the existing theory of sex allocation. Local resource competition and the Trivers-Willard hypothesis have been usefully applied to several data sets, and preliminary experimental work has supported the main tenets of theory. By contrast, several data sets lack explanation, and provide challenges to theoreticians. The high frequency of bias in marsupials does not result from data-dredging, as bias is usually reported in descriptive accounts of marsupial reproduction, without recourse to any theoretical or mechanistic explanations. It is not possible to distinguish whether the marsupial mode of reproduction is well suited to manipulate sex allocation, or whether it facilitates measurement of biased sex allocation. As for most eutherians and birds, the mechanism of prenatal sex allocation is unknown for any marsupial. However, the current interest in sex-determining mechanisms in marsupials suggests a profitable avenue for collaboration between geneticists, physiologists and evolutionary ecologists.

Full text
Abstract:
Marsupial moles (genus Notoryctes) are the most highly specialised burrowing marsupials. The specialisations of the appendicular musculo-skeletal system of the marsupial moles are extensive and widespread; the major alterations are concentrated in, but not restricted to, the forelimb. Many of the derived features of the muscular system appear to be adaptations for improving the mechanical advantage of the limbs for burrowing. A number of the specialisations of the muscular system of the marsupial moles are convergent with those previously documented in other fossorial mammals, including golden moles, rodents and armadillos. There are, however, a number of unique specialisations of the musculo-skeletal system of Notoryctes. The functional morphology of the locomotor apparatus of marsupial moles is interpreted on the basis of the descriptions of the anatomy of the skeletal and muscular systems. The burrowing technique of the marsupial moles is a modified form of the parasagittal digging method that is used by other fossorial mammals, such as golden moles, armadillos and some rodents including pocket gophers. Differences in the functional morphology of the hindlimb between marsupial moles and other fossorial mammals are a reflection of the fact that marsupial moles do not construct permanent open burrow systems, but instead constantly dig through loose soil, backfilling as they progress. The functional morphology of the tail is uniquely specialised in the marsupial moles to function as the fifth limb during the pentapedal burrowing locomotion of marsupial moles. The remains of Miocene fossil marsupial mole, while clearly pleisiomorphic with respect to the appendicular skeletal morphology of modern notoryctids, demonstrate a high degree of specialisation for digging. It is hypothesised that the Miocene marsupial mole was already substantially specialised for a fossorial lifestyle, and thus pre-adapted for a subterranean lifestyle developed in correlation with the desertification of the Australian continent. Phylogenetic affinities of marsupial moles within the Marsupialia have long been enigmatic. While specialisation of the musculo-skeletal system have been so widespread as to obscure almost any phylogenetically relevant patterns, there is some evidence to support an association between notoryctids and peramelid bandicoots. Interspecific differences between the two species of marsupial moles, Notoryctes typhlops and N. caurinus, are minor but do support the separation of the two species.

Abstract:
Sabe-se que a atividade da glicose-6-fosfato desidrogenase eritrocitária do marsupial brasileiro Didelphis marsupialis é cerca de 15 a 20 vezes a encontrada nos eritrócitos humanos. Pretendendo-se investigar se esta hiperatividade também se encontra ou não aumentada nas outras enzimas eritrocitárias, levou-se a efeito a dosagem das atividades das enzimas glicolíticas bem de outras enzimas relacionadas ao metabolismo óxido-redutor do eritrócito do marsupial. Alguns dados bioquímicos sorológicos, hematológicos e imunológicos foram também obtidos. Assim sendo, as seguintes enzimas eritrocitárias foram estudadas: hexoquinase, glicose fosfato isomerase, fosfofrutoquinase, aldolase, triose fosfato isomerase, gliceraldeido-3-fosfato desidrogenase, fosfogliceratoquinase, difosfoglicerato mutase, monofosfoglicerato mutase, enolase, piruvato quinase, lactato desidrogenase, glicose-6-fosfato desidrogenase, 6-fosfogliconato desidrogenase, glutationa redutase, glutationa peroxidase, glutationa S-transferase, nicotinamida adenina dinucleotideo fosfato diaforase, nicotinamida adenina dinucleotideo meta-hemoglobina redutase, superóxido dismutase, aspartato aminotransferase, adenilato quinase, adenosina desaminase e acetilcolinesterase. Embora a maioria das enzimas estudadas tenham revelado atividades semelhantes às encontradas nos eritrócitos humanos, foram observados aumentos significativos da hexoquinase, piruvato quinase e glutationa S-transferase. Entretanto, a atividade da glutationa peroxidase apresentou grande aumento de atividade, cerca de dez a doze vezes a encontrada nos eritrócitos humanos, talvez agindo em conjunto com a hiperatividade da glicose-6-fosfato desidrogenase da ordem de dez a quinze vezes já descrita nos eritrócitos humanos
It is known that erythrocyte glucose-6-phosphate dehydrogenase specific activity of Didelphis marsupialis is about 15-20 times higher than human red cells. In order to investigate whether this hyperactivity is extended or not to other red cell enzymes, it was proposed to ascertain the activity of the glycolytic enzymes as well as other related to the redox metabolism of the opossum erythrocyte. Some biochemical, hematological and immunological data were also assayed as well. That being so, the following red cell enzymes were assayed: hexokinase, glucose phosphate isomerase, phosphofructokinase, aldolase, triose phosphate isomerase, glyceraldehyde-3-phosphate dehydrogenase, phosphoglycerate kinase, diphosphoglycerate mutase, monophosphoglycerate mutase, enolase, pyruvate kinase, lactate dehydrogenase, glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, glutathione reductase, glutathione peroxidase, glutathione S-transferase, nicotinamide adenine dinucleotide phosphate diaphorase, nicotinamide adenine dinucleotide metahemoglobin reductase, superoxide dismutase, aspartate amino-transferase, adenylate kinase, adenosine deaminase and acetylcholinesterase . Although most of the enzymatic activities disclosed to be similar to humans, some enzymes exhibited high activities as the hexokinase, pyruvate kinase and glutathione-S-transferase, about three to four times in relation to human. However the glutathione peroxidase presented overwhelming activity, at the order of ten-twelve times the human enzyme, perhaps working together the glucose-6-phosphate dehydrogenase hyperactivity at the order of ten-fifteen times already described in the marsupial erythrocytes

Abstract:
This thesis explored the evolutionary trajectory of marsupials, focusing primarily on the Australasian marsupial fauna, and used a phylogenetic inference approach that combines molecular, ecological and fossil data sets. A first study provided the most complete and accurate (to-date) species-level marsupial phylogeny by using the most taxonomically complete set of nuclear and mitochondrial loci. In a second study, DNA and fossils from extinct and modern taxa were used to infer the evolution of macropods. A third project inferred the most complete (to-date) time-calibrated phylogeny of Diprotodontia. By incorporating fossil data, this last project revealed apparent competitive displacement of Vombatiformes (koala and wombats) by Macropodiformes (kangaroos) from the Late Miocene onwards, and a long (~25 million year) lag in the evolution of herbivory among marsupials compared to placental mammal faunas.

In this thesis I utilize the recently sequenced genomes of the South American grey short-tailed opossum (Monodelphis domestica), tammar wallaby (Macropus eugeniz') and the platypus (Ornithorhynchus anatinus) to identify and characterize immune genes in order to fill in the gaps in our understanding of evolution of the immune systems in non-eutherian mammals. Many of these genes have proved elusive to identify using conventional lab strategies and automated genome annotation pipelines. I discovered divergent immune genes using bioinformatic protocols that I developed and compiled this sequence information in a publicly available database. I examined species—specific expansions of major immune gene clusters. Using these genes, I developed a comprehensive marsupial immune gene set which is used to compare the expression profiles of the two tammar wallaby thymuses to gain insights into the functional roles of these organs. The availability of these immune sequences allows for analysis of large-scale expression studies and development of marsupial- and monotremespecific reagents.

Abstract:
The rise in antimicrobial resistance and paucity of new antimicrobial compounds calls for alternatives to traditional antibiotics. Antimicrobial peptides (AMPs) have emerged as potential candidates. Cathelicidins are a major family of AMPs in mammals which form part of innate immunity through antimicrobial and immunomodulatory functions. Marsupial and monotreme cathelicidins are of particular interest due to their involvement in protecting immunologically naive young during development in the pouch via expression in the pouch lining and milk where they modulate microbial flora and provide passive immunity. As such, the cathelicidin gene family has expanded in marsupials and monotremes, with a high number of cathelicidins in the tammar wallaby, gray short-tailed opossum and platypus. However our knowledge is limited to these species and functional studies involving antimicrobial activity are lacking. This thesis describes the characterisation of cathelicidins in the Tasmanian devil, koala and echidna, and investigates the antimicrobial function of all marsupial and monotreme cathelicidins. As expected, cathelicidins have expanded in the Tasmanian devil and koala, resulting in a high number of cathelicidins which were widely expressed throughout the body, including in pouch lining and milk. Only a single cathelicidin was identified in the echidna due to the quality of the genome. Out of 26 cathelicidins tested, six displayed broad-spectrum antibacterial activity against gram-negative and positive bacteria, including methicillin-resistant Staphylococcus aureus. One koala cathelicidin rapidly inactivated C. pecorum and significantly reduced the number of chlamydial inclusions in vitro. Activity was reduced in the presence of serum and whole blood, and peptides displayed varying levels of haemolytic and cytotoxic activity. Many cathelicidins did not display antimicrobial activity and future work is required to explore their potential immunomodulatory properties. The results presented in this thesis have advanced our understanding of cathelicidins in marsupials and monotremes on a genetic and functional level, and highlights their potential as novel therapeutics in the future.

Abstract:
Many Australian marsupial species require active population management to ensure their survival in the wild. Such management should be based on a sound understanding of species biology. This thesis explores how knowledge of reproduction and genetics can be applied to the management of three Australian marsupial species faced with contrasting management scenarios. The ??vulnerable?? greater bilby is the sole remaining desert bandicoot in Australia. They are a secretive, solitary species whose mating system is unclear. This research examined temporal changes in genetic diversity within two captive breeding programs utilising different management strategies. Using seven microsatellite loci, this study found the regular translocation of new individuals into the population maintained genetic diversity. Parentage analysis revealed the bilby to have a promiscious mating system. Sires and non-sires could not be distinguished by morphological traits. The tammar wallaby is a polygynous, solitary species that is threatened on mainland Australia, but overabundant on some offshore islands. The population genetics of tammars from the Abrolhos Islands in Western Australia were examined using nine autosomal and four Y-linked microsatellite loci, and mitochondrial DNA. There was a relationship between island size, population size and genetic diversity. The Abrolhos populations have significantly lower genetic diversity and are more inbred than mainland tammars and all sampled populations were significantly differentiated. The Abrolhos and mainland populations should be treated as separate Management Units. The eastern grey kangaroo is a gregarious, polygynous species that is often locally overabundant. To determine traits influencing male reproductive success, behavioural, morphological, physiological and genetic data were examined and showed dominance status, body size and testosterone concentrations were important factors. Sires were also significantly more heterozygous and genetically dissimilar to females, than non-sires. As body condition influences individual fitness, and management decisions; five body condition indices (BCI) calculated from morphological data were validated using serum biochemistry and haematology in two kangaroo populations with contrasting body condition. Blood parameters were found to be more reliable indicators of condition, questioning the credibility of BCIs currently used in management. These studies demonstrate the importance of reproductive and genetic data in assisting wildlife management, regardless of a species conservation status.

Abstract:
Abstract Avestec has successfully developed proprietary contact-based flying robots (SKYRON™) for ultrasonic (UT) A scan measurement of metallic surfaces. The technology has been successfully validated with many asset owners in onshore and offshore industrial campaigns. Although the flying contact-based robot can easily access most asset surfaces to perform inspections, it has some limitations when it comes to challenging and dense spaces. Such shortcoming is exasperated specially for pipe inspection in offshore environments. Pipes are usually located in the vicinity of one another or in close proximity to walls or other structures, which makes it practically impossible for an unmanned aerial vehicle (UAV) to reach to every side of the pipe and carry out circumferential (3/6/9/12) measurement as needed. In order to enhance the advantages of contact-based aerial robots and overcome the aforementioned limitations, a marsupial robotic methodology has been followed by means of combining the proprietary contact-based UAV and a custom omni-directional mini crawler in a collaborative robotics fashion. An advanced marsupial connection between the two robots both in terms of mechanical (e.g., carrier/passenger roles) and control mechanism (e.g. master/slave roles) and versatility of the task deliveries can potentially introduce a lot of advantages over a single flying robot for asset inspection. In addition, Phased Array Ultrasonic (PAUT) sensory package has been integrated into the marsupial robot to expand NDT capabilities for inspection including thickness measurements, corrosion mapping, defect detection (e.g. such as cracks, voids, and pits caused by corrosion), weld inspection and many more.
