Abstract:
The particle-size distributions of the ingesta of the sacciform forestomach in free-ranging animals of a grazing macropod species [Macropus eugenii (tammar wallaby)], a grazer/browser [Macropus parma (parma wallaby)], a browser/grazer [Petrogale penicillata (brush-tailed rock-wallaby)] and a browser [Wallabia bicolor (swamp wallaby)] from Kawau Island, New Zealand, were compared with those of captive animals maintained on a standing ryegrass (Lolium perenne) sward. Nutrient digestibility was also measured in tammar and parma wallabies fed ryegrass or browse, i.e. fresh mahoe (Melicytus ramiflora) and this was related to particle-size distributions of the ingesta.There were significant differences in the particle size distributions of digesta from tammar and parma wallabies in the wild but not in captivity. In free-ranging animals the ingesta from both browsing species, the brush-tailed rock-wallaby and the parma wallaby, contained consistently greater proportions of coarse particles and smaller proportions of fine particles than did those of the tammar wallaby. These differences may be correlated with reported differences in their tooth morphologies. However, the presence of significant differences in particle-size distributions of the digesta between brush-tailed rock-wallabies and parma wallabies when constrained to grass, despite reported similarities in their tooth morphology, suggests that factors other than tooth morphology contribute to differences in the oral processing of food by browsing and grazing macropods. There were greater proportions of grass fragments in the coarse than in the finer fractions of ingesta from free-ranging brush-tailed rock-wallabies, indicating that this species is less effective at chewing grass.There were no overall differences between tammar and parma wallabies in the digestibilities of organic matter, neutral-detergent fibre (NDF) or acid-detergent fibre (ADF) but the NDF and ADF digestibilites of both species increased significantly with increase in the proportion of fine ingesta particles and with increase in mass of fermentative digesta.These findings indicate the importance of oral processing to digestive efficiency in macropods and the relationship between oral processing and tooth morphology.

Abstract:
The temporal association between drinking and feeding in four captive tammar wallabies (Macropus eugenii Desmarest) maintained on various foods is examined. Tammars maintained on cubed carrots never drank. In tammars fed pellets food-associated drinking took place and 77.5% (7.4, s.e.) of drinking episodes commenced within 60 s of the beginning or end of a feeding event. Drinking events occurred singly, were of short duration and increased in frequency but not duration, when low-quality pellets were fed. Food- associated drinking in the tammar may result from the induction of drinking episodes of relatively fixed duration by an oropharyngeal reflex.

Abstract:
Marsupial mammals show extraordinary karyotype stability, with 2n = 14 considered ancestral. However, macropodid marsupials (kangaroos and wallabies) exhibit a considerable variety of karyotypes, with a hypothesised ancestral karyotype of 2n = 22. Speciation and karyotypic diversity in rock wallabies (Petrogale) is exceptional. We used cross species chromosome painting to examine the chromosome evolution between the tammar wallaby (2n = 16) and three 2n = 22 rock wallaby species groups with the putative ancestral karyotype. Hybridization of chromosome paints prepared from flow sorted chromosomes of the tammar wallaby to Petrogale spp., showed that this ancestral karyotype is largely conserved among 2n = 22 rock wallaby species, and confirmed the identity of ancestral chromosomes which fused to produce the bi-armed chromosomes of the 2n = 16 tammar wallaby. These results illustrate the fission-fusion process of karyotype evolution characteristic of the kangaroo group.

Full text
Abstract:
Surveys of two wallaby species on Kawau Island, New Zealand, indicated that their distribution was stable so as to permit niche partitioning. Multivariate analysis of environmental factors associated with the relative distribution of tammar and parma wallabies suggested that their distribution may be influenced by the availability of fresh water. Tammar wallabies have greater renal size, mass and relative medullary area than parma wallabies and thus may have greater renal water-conserving capabilities. The tammar colon is significantly longer than that of the parma wallaby and the water content of distal digesta is lower in tammar than in parma wallabies, indicating that the former species may also have greater colonic water-resorption capabilities. A laboratory comparison of the water consumption of tammar and parma wallabies showed that the former drink significantly less than the latter.The superior ability of tammar wallabies to colonise drier areas may have contributed to their survival in the presence of the closely related parma wallaby.

Abstract:
We investigated the effects of a ground, pelleted diet versus natural forage on the gross morphology of the gastrointestinal tract of a medium-sized (5–7 kg body mass) macropodid marsupial, the tammar wallaby (Macropus eugenii). The empty wet mass (g) of the small intestine of tammar wallabies maintained on a pelleted diet for 6 weeks was 22% greater than that of animals maintained on natural forage, once body mass was taken into account by ANCOVA. Similarly, the body-mass-adjusted length of the tammar wallaby caecum and proximal colon combined was 25% longer in animals maintained on the pelleted diet compared with those maintained on forage. Our data suggest that food particle size may be directly involved in controlling the size of the post-gastric alimentary tract in tammar wallabies, and thus in their diet choice and nutritional ecology. Notably, this is the first study that links phenotypic plasticity of the gut directly to diet in a marsupial and we conclude that the tammar wallaby is an excellent model for exploring the causes and consequences of digestive plasticity in macropodid marsupials.

Abstract:
In the present study, male and female tammar wallabies were immunised with whole tammar wallaby sperm in adjuvant. An assay for sperm antibodies using a live sperm ELISA has been developed to detect sperm surface antigens and used to validate an assay using a 3-[(3-cholamidopropyl) dimethylammonio]-1 propanesulfonate (CHAPS) membrane extract of whole tammar wallaby sperm. The tests were used to monitor the immune response to whole sperm in both male and female tammar wallabies. Antisera with a limited array of specificities were generated, with those locating to the midpiece region of the sperm appearing the most likely candidates for targets for fertility perturbation based on immunofluorescence of fixed and non-fixed sperm. These systemically generated antibodies were demonstrated to have access to both the female and male tammar reproductive tracts and were found on ejaculated sperm and antibodies from female sera and follicular fluid-labelled fresh ejaculated sperm from non-immunised males. Preliminary sequencing of these proteins has identified some possibilities for further investigation.

Abstract:
With the accelerating recognition of the power of comparative genomics, there is now enormous interest in sequencing the genomes of a broad range of species. Marsupials diverged at an important evolutionary time. The model Australian marsupial, the tammar wallaby (Macropus eugenii), has long been a resource for biological and genetic studies of marsupials, and the availability of a bacterial artificial chromosome (BAC) library will be a valuable resource in these studies. A tammar wallaby BAC library was constructed using pRazorBAC vector. It contains 55 296 clones with an average insert size of 108 kb, representing 2.2 times coverage of the wallaby genome (based on an estimated 2.7 × 109 bp haploid genome size). The library was arrayed in 384-well plates, and spotted in duplicate onto nylon membranes. Screening these membranes has yielded clones containing 34 single-copy genes distributed over the genome, while it failed for only one gene. Each probe isolated 1–12 BAC clones and, to date, no chimeric clones have been found. This BAC library will constitute an invaluable resource for creating physical maps, positional cloning of genes and other sequences in the tammar wallaby, as well as comparative mapping studies in mammals.

Abstract:
We compared changes in the particle size profiles, permeability and elastic shear modulus of digesta in the forestomach and rumen of fasting tammar wallabies (Macropus eugenii eugenii) and fistulated sheep respectively that had been fed chopped lucerne hay. The wet mass of digesta in the tammar wallaby stomach declined curvilinearly over 24 h. The relative proportion of particles >2 mm in size in tammar wallaby digesta increased significantly and that of particles <2 mm in size decreased significantly after 12 h of fasting. This contrasted with the sheep rumen digesta, in which the relative proportions of coarse and fine particles did not change significantly over time. The permeability of wallaby digesta increased significantly after 24 h whilst that of sheep declined. All samples of tammar digesta had a significant elastic component (G′) that was preserved throughout the period of fasting. Interaction between component particles was significant at all times, digesta behaving as a weak gel. The ratio of energy lost to energy stored during flow of digesta tended to decrease during the period of fasting, indicating an increase in behaviour as an elastic solid. The relationship between G′ and dry matter content and mean particle size indicated that these phenomena resulted from progressive loss of finer digesta particles and that digestion in the wallaby stomach, via permeation of the particulate by the fluid phase, was possible for up to 33 h after eating.

Abstract:
Androgens induce the differentiation of the urogenital sinus (UGS) to form a prostate. An early marker of this response is upregulation of the transcription factor Nkx3.1 in the urogenital epithelium in the precursors of prostatic buds. In tammars, prostate differentiation begins ~3 weeks after birth and after the time the testis starts to secrete androgens, and 2 weeks after androgen stimulated Wolffian duct differentiation. The reason for this delay in prostate differentiation is unexplained. Androgen receptors are present in the UGS, and the potent androgen, androstanediol, induces prostatic development in females. Whilst androgens may diffuse into cells by across the cell membrane, there is increasing evidence that steroids are also internalised actively via the cell-surface transport molecule Megalin. We are exploring the possibility that the delay may be related to the establishment of a Megalin-mediated pathway. Megalin is a cell surface receptor expressed on epithelia and mediates the endocytosis of a wide range of ligands, including SHBG-bound sex steroids. Megalin action is regulated by Receptor Associated Protein (RAP), which acts as an antagonist to Megalin action. This study cloned partial sequences of Megalin, RAP and Nkx3.1 and examined their expression in the developing urogenital sinus of the tammar wallaby using RT–PCR. The cellular distribution of Megalin protein in the developing UGS was examined using immunohistochemistry. Megalin, RAP and Nkx3.1 in the tammar were all highly conserved with eutherian orthologueues. Megalin and Nkx3.1 transcripts were detected in the liver, kidney, ovary, testis and developing urogenital sinus of male and female tammars. In the developing UGS of the tammar, there was strong staining for Megalin protein in the urogenital epithelium with some diffuse staining in the surrounding mesenchyme. Together, these results suggest that Megalin could be a key gene in the mediation of androgen action in prostatic development in the tammar wallaby.

Abstract:
[Truncated abstract] Understanding the effect that the disturbance of habitat by humans has on the population dynamics and ecology of wild animals is critical for the management of these populations. By understanding the demographic effects of disturbance the ways in which a population can be managed to increase or decrease its rate of change in size also become apparent. This thesis describes the effect that human disturbance, through the establishment of a large naval base, has had on the population dynamics and ecology of tammar wallabies (Macropus eugenii) on Garden Island, Western Australia. The disturbance of the environment on the HMAS Stirling Naval Base included the establishment of large areas of irrigated and fertilised couch grass (Cynodon dactylon) that increased and made virtually constant the amount of food available to the tammars in that area. In addition, traffic associated with the naval base resulted in large numbers of tammar wallabies being killed by vehicles. The effects of these disturbances were determined by comparing population dynamics, through vital rates of survival and fecundity and population growth rates, and spatial ecology, through the size of the animals' home ranges, in three areas of Garden Island. The three areas were the naval base (highly disturbed), southern bushland (adjacent to the naval base) and the northern bushland (undisturbed). The tammars on the naval base were in better body condition than those living in the two bushland areas of the island. ... When the impact of road-kills was removed, increased to 1.150.101 per year on the naval base and 0.960.076 per year in the southern bushland. Fecundity transitions, defined as the product of the rates of birth and pouch-young survival, and adult survival rates were lower in the bushland areas compared with the naval base in two of the three years, which were the main reasons for the lower estimates. There were no significant differences in the size of the tammars' home ranges between areas with modified or unmodified habitats or between the sexes (P>0.05). In summer the mean size of the home ranges was 3.90.66 ha, which was larger than winter when home ranges were 3.20.54 ha, but this difference failed to reach significance (P=0.058). These results indicate that the modification of the tammars' habitat has probably not caused significant changes in the size of the animals' home ranges. The size of the home ranges of tammar wallabies is likely to be determined by a complex interaction of many factors, and habitat modification alone has not been sufficient to cause substantial changes. The results presented in this thesis demonstrate that the disturbance caused by the establishment of the naval base on Garden Island has altered the population dynamics of the tammars wallabies, through increasing in the amount of food available to the tammars and through high numbers of road-kills. These results also demonstrate how gaining detailed knowledge of population dynamics can have direct application to managing the impact of disturbance on populations of wild animals.

Abstract:
Microsatellites are simple repetitive DNA sequences that are used as genetic markers throughout the biological sciences. The high levels of variation observed at microsatellite loci contribute to their utility in studies at the population and individual levels. This variation is a consequence of mutations that change the length of microsatellite repeat tracts. Current understanding suggests that most mutations are caused by polymerase slippage during DNA replication and lead to changes of a single repeat unit in length, but some changes involving multiple repeats can also occur. Despite this simplistic overview, there is evidence for considerable heterogeneity in mutation processes between species, loci and alleles. Such complex patterns suggest that other mechanisms, including those associated with DNA recombination, are also involved in the generation of microsatellite mutations. Understanding which mutational mechanisms are responsible for variation at microsatellite markers is essential to enable accurate data interpretation in genotyping projects, as many commonly used statistics assume specific mutation models. I developed microsatellite markers specific to the X and Y chromosomes and an autosome in the tammar wallaby, Macropus eugenii, and investigated their evolutionary properties using two approaches: indirectly, as inferred from population data, and directly, from observation of mutation events. First, I found that allelic richness increased with repeat length and that two popular mutation models, the stepwise mutation model and the infinite allele model, were poor at predicting the number of alleles per locus, particularly when gene diversity was high. These results suggest that neither model can account for all mutations at tammar wallaby microsatellites and hint at the involvement of more complex mechanisms than replication slippage. I also determined levels of variation at each locus in two tammar wallaby populations. I found that allelic richness was highest for chromosome 2, intermediate for the X chromosome and lowest for the Y chromosome in both populations. Thus, allelic richness varied between chromosomes in the manner predicted by their relative exposure to recombination, although these results may also be explained by the relative effective population sizes of the chromosomes studied. Second, I used small-pool PCR from sperm DNA to observe de novo mutation events at three of the most polymorphic autosomal markers. To determine the reliability of my observations I developed and applied strict criteria for scoring alleles and mutations at microsatellite loci. I observed mutations at all three markers, with rate variation between loci. Single step mutations could not be distinguished because of the limitations of the approach, but 24 multi-step mutations, involving changes of up to 35 repeat units, were recorded. Many of these mutations involved changes that could not be explained by the gain or loss of whole repeat units. These results imply that a large number of mutations at tammar wallaby microsatellites are caused by mechanisms other than replication slippage and are consistent with a role for recombination in the mutation process. Taken as a whole, my results provide evidence for complex mutation processes at tammar wallaby microsatellites. I conclude that careful characterisation of microsatellite mutation properties should be conducted on a case-by-case basis to determine the most appropriate mutation models and analysis tools for each locus. In addition, my work has provided a set of chromosome-specific markers for use in macropod genetic studies, which includes the first marsupial Y chromosome microsatellites. Sex chromosome microsatellites open a new range of possibilities for population studies, as they provide opportunities to investigate gene flow in a male context, to complement data from autosomal and maternally-inherited mitochondrial markers.

"In the study reported in this thesis, a PCR-based approach was used to isolate the b-like globin genes that are present in the tammar wallaby, Macropus eugenii, including the gene that encodes the w-globin chain. Three -like globin genes (b-, e-, w-) that had previously been described at the protein level in the tammar wallaby were characterised. w-globin orthologues were also identified in a wide range of marsupial species, and in one of these species, the dunnart (Sminthopsis crassicaudata), the complete DNA sequence of the w-globin gene was determined. Southern analysis in the dunnart and in situ hybridisation in the tammar wallaby, provided evidence for the unexpected conclusion that w-globin is not part of the -globin gene cluster in these species. RT-PCR studies using RNA isolated from a new-born dunnarts confirmed that w-globin is expressed in this species. Therefore, this is the first report of an "orphaned" b-like globin gene that is expressed in a vertebrate." --p. 6.

Abstract:
As a representative of Australian marsupials, the recently sequenced genome of a model kangaroo, the tammar wallaby (Macropus eugenii) provides unique opportunities to understand the organisation and evolution of the genome in marsupials, and in mammals in general. Comparisons with the fully sequenced genome of the Brazilian short-tailed opossum Monodelphis domestica allow comparing the genomes of American and Australian marsupials. The general aims of this thesis were to examine the extent to which part of the genome has been conserved in marsupials and in therian mammals, as well as to explore the organisation and evolution of the largest gene family in mammals, whose members code for olfactory receptors. As part of the KanGo’s task of establishing a map of the tammar genome, the comparative map of the long arm of chromosome 6 in the tammar wallaby was prepared. Several syntenic blocks of genes were mapped to tammar wallaby 6q and it was found that there are only few rearrangements between the tammar wallaby and the opossum in this part of the genome. However, the genomic parts orthologous to tammar wallaby 6q reside on several chromosomes in human, dog, and chicken, suggesting that the fusion occurred in the marsupial ancestors and remained conserved during marsupial evolution. I then developed a strategy to explore the OR gene (ORG) family in the tammar wallaby. Sequences corresponding to ORGs were extracted from the first assembly of the tammar wallaby genome and sequences classified into families and subfamilies. BACs bearing conserved mammalian ORG clusters were isolated and physically mapped in tammar wallaby. Comparison with the opossum OR repertoire revealed that these two distantly related marsupials share a very similar ORG superfamily. Conserved features include the total numbers of genes, families, and subfamilies, gene distribution across the families and subfamilies, patterns of expansions and contractions in families and subfamilies and genomic location of major ORG clusters. I then examined in detail the genomic organisation of a highly conserved ORG cluster that lies near the MHC locus in several mammals. By making a BAC contig over the entire chromosome region I found that this cluster is conserved in tammar wallaby and carries almost the same genes as in the opossum. Preliminary analysis of platypus ORGs dates the origin of this cluster back to the common ancestor of therian and monotreme mammals more than 166 million years ago, and provides examples of both conservation and adaptation of some genes in this cluster. My general conclusion is that the two distantly related marsupial species have retained very similar genomes since their divergence 70 million years ago. This conservation is reflected both at the level of genome arrangement, and at the organisation and evolution of gene families. This conservation is in marked contrast to the variability observed between eutherian groups, both in gross gene arrangement and in the constitution of the ORG family, suggesting that marsupial genomes have been evolving more slowly than other mammals, possibly due to some unique features of their physiology and way of life.

Abstract:
Abstract In this study we investigated the energy efficiency of kangaroo locomotion as a function of hopping speed. We tracked the motion of the joints and body segments of the Tammar wallaby (Macropus eugenii) using high-speed digital capture. Kinematic observations revealed that the height of the wallaby’s jump is uncoupled from its velocity for the speed ranges measured. Computing internal torques at the joints during the stance phase revealed a back and forth pattern of torque flow between the lower and upper links.
