The banded hare-wallaby (Lagostrophus fasciatus) is an endangered macropodid currently restricted to Bernier and Dorre Islands in Shark Bay, Western Australia. Historically, L. fasciatus was also recorded on the Australian mainland from far western Australia, where it became locally extinct early in the twentieth century. Here we discuss an overlooked museum specimen of L. fasciatus collected in the mid-nineteenth century near Adelaide, South Australia. This specimen considerably extends the known historical distribution of L. fasciatus, validates anecdotal reports of the species from South Australia made by early Australian naturalists, and forms the basis for our description of a new subspecies.

Monitoring programs for populations of small or medium-sized animals often use live-capture or photo-monitoring trapping methods to estimate population size. The banded hare-wallaby (Lagostrophus fasciatus), a small macropodiform marsupial, does not readily enter traps or have individually unique distinguishing physical features and is consequently difficult to monitor using these methods. Isolating DNA from faecal material to obtain individual genotypes is a promising monitoring technique and may present an alternative approach for this species. We developed novel species-specific microsatellite markers and undertook trials to assess faecal DNA degradation in ambient environmental conditions at two locations where this species has been translocated. The quality of DNA yielded from faecal pellets was evaluated through amplification failure and genotyping error rates of microsatellite markers. Error rates were compared for different treatments and exposure duration across multiple individuals. DNA was successfully obtained from all samples and error rates increased with exposure duration, peaking after 14–30 days depending on the site and treatment. The level of solar exposure was the most significant factor affecting degradation rate but both this and exposure duration had significant effects on amplification failure. Analysing DNA obtained from faecal pellets may represent a practical non-invasive method of deriving population estimates for this species and warrants further development.

Kangaroos and kin (Macropodiformes) are the most conspicuous elements of the Australasian marsupial fauna. The approximately 70 living species can be divided into three families: (1) Hypsiprymnodontidae (the musky rat kangaroo); (2) Potoroidae (potoroos and bettongs); and (3) Macropodidae (larger kangaroos, wallabies, banded hare wallaby and pademelons). Here we examine macropodiform relationships using protein-coding portions of the ApoB, BRCA1, IRBP, Rag1 and vWF genes via maximum parsimony, maximum likelihood and Bayesian methods. We estimate times of divergence using two different relaxed molecular clock methods to present a timescale for macropodiform evolution and reconstruct ancestral states for grades of dental organisation. We find robust support for a basal split between Hypsiprymnodontidae and the other macropodiforms, potoroid monophyly and macropodid monophyly, with Lagostrophus as the sister-taxon to all other macropodids. Our divergence estimates suggest that kangaroos diverged from Phalangeroidea in the early Eocene, that crown-group Macropodiformes originated in the late Eocene or early Oligocene and that the potoroid–macropodid split occurred in the late Oligocene or early Miocene followed by rapid cladogenesis within these families 5 to 15 million years ago. These divergence estimates coincide with major geological and ecological changes in Australia. Ancestral state reconstructions for grades of dental organisation suggest that the grazer grade evolved independently on two different occasions within Macropodidae.

Many Australian mammal species now only occur on islands and fenced mainland havens free from invasive predators. The range of one species, the banded hare-wallaby (Lagostrophus fasciatus), had contracted to two offshore islands in Western Australia. To improve survival, four conservation translocations have been attempted with mixed success, and all occurred in the absence of genetic information. Here, we genotyped seven polymorphic microsatellite markers in two source (Bernier Island and Dorre Island), two historic captive, and two translocated L. fasciatus populations to determine the impact of multiple translocations on genetic diversity. Subsequently, we used population viability analysis (PVA) and gene retention modelling to determine scenarios that will maximise demographic resilience and genetic richness of two new populations that are currently being established. One translocated population (Wadderin) has undergone a genetic bottleneck and lost 8.1% of its source population’s allelic diversity, while the other (Faure Island) may be inbred. We show that founder number is a key parameter when establishing new L. fasciatus populations and 100 founders should lead to high survival probabilities. Our modelling predicts that during periodic droughts, the recovery of source populations will be slower post-harvest, while 75% more animals—about 60 individuals—are required to retain adequate allelic diversity in the translocated population. Our approach demonstrates how genetic data coupled with simulations of stochastic environmental events can address central questions in translocation programmes.

Sex ratio, reproduction, body condition and morphology of banded (Lagostrophus fasciatus) and rufous (Lagorchestes hirsutus) hare-wallabies were assessed on Dorre and Bernier Islands. Data are derived from 236 banded hare-wallabies and 161 rufous hare-wallabies captured between 1959 and 1999. The sex ratio of captured banded hare-wallabies tended to be female-biased (0.79: 1 male: female) but was not a significant departure from parity. In contrast, pouch young tended towards a male bias at 1.35: 1. Females produced 1–2 young per year. They were capable of producing young at 1000 g, but the incidence of females carrying pouch young or lactating increased from 39% for females of 1000–1400 g to 80% for females of 1401–1800 g, then decreased slightly to 76% for females >1800 g. Births occurred throughout the year but there was some indication of a decline in the latter half of the year. Captured banded hare-wallabies ranged in weight from 850 to 2300 g. Animals on Dorre Island were in significantly better body condition than those on Bernier Island, although this could be an artefact of their shorter pes length. There was no evidence of sexual dimorphism and no differences in morphological measurements taken, other than pes length, between the two island populations. The sex ratio of captured rufous hare-wallabies was close to parity at 0.99: 1 and for pouch young tended to be male-biased at 2: 1. The smallest female with young weighed 1215 g, but the incidence of females carrying pouch young or lactating increased from 43% for females of 1215–1660 g to 61% for females of 1661–2015 g and 100% for females >2015 g. Females carried pouch young in all months sampled (March–September) and one incidence of twinning was noted. Captured rufous hare-wallabies weighed 600–2550 g. Body condition was similar for males and females and between islands, but smaller females of reproductive age were in poorer body condition than larger females. There was no evidence of sexual dimorphism but pes lengths of animals on Dorre Island were significantly shorter, head lengths longer and tail lengths shorter, than those on Bernier Island. Rufous hare-wallabies appear to show regional variation in body size, being smaller in the wetter and warmer Tanami/Alice Springs region and larger on the drier and cooler Shark Bay islands.

Current phylogenetic hypotheses of the relationships of Australian marsupials were tested by microcomplement fixation of albumin. The study involved antisera to albumins of 56 species, and cross- reactions to albumins of 199 species. The most notable and controversial features of the study were as follows. (1) Two major lineages are evident among the Australian marsupials- bandicoots-dasyuroids and diprotodontids; the marsupial mole represents a third lineage. (2) The honey possum Tarsipes is clearly a diprotodontid. (3) Acrobates and Distoechurus are monophyletic, but they are not burramyids; they are closely related to Tarsipes; moreover the Acrobates-Distoechurus-Tarsipes clade may be close to petaurids. (4) The New Guinean species of Antechinus are more closely related to the New Guinean Murexia than to Australian species of Antechinus. (5) The bandicoots fall into two groups-the New Guinean genera and the Australian genera; the bilby, Macrotis lagotis, is not clearly distinct from the bandicoots, and may be monophyletic with the New Guinean genera. (6) The banded hare-wallaby Lagostrophus is clearly the sister-group to all other extant macropodines, and may be monophyletic with potoroines rather than macropodines. (7) The genus Macropus may be paraphyletic. (8) The tree-kangaroos Dendrolagus may be closely related to the rock-wallabies and their allies (Petrogale, Peradorcas and Thylogale). (9) The genus Pseudocheirus (ringtail possums) is paraphyletic and its species are highly divergent at the molecular level. (10) The cuscuses (genus Phalanger) are probably a monophyletic assemblage.

In an effort to learn more about the potential for reintroduction of hare-wallabies to sites in Australia, 34 captive-bred hare-wallabies were released onto Peron Peninsula within the Shark Bay World Heritage Property in 2001 as part of an experimental reintroduction program. One objective of this experiment was to characterise their behaviour and daytime refugia to identify suitable habitat for future releases. The mala (Lagorchestes hirsutus) and merrnine (Lagostrophus fasciatus) were fitted with radio-transmitters and tracked daily. Merrnine were more faithful to a previously occupied shelter than mala. Mala maintained a solitary daytime habit at all times. Within the study area, mala preferentially sought low-lying vegetation primarily comprising the species Lamarchea hakeifolia, which provided dense cover up to 1 m in height, under which they constructed scrapes. L. hakeifolia was preferred as shelter vegetation instead of Triodia (spinifex) hummocks, despite Triodia hummock habitat being preferred by mala in central Australia. Merrnine occupied taller vegetation with an open understorey to 1.5 m, although the extremity of the understorey remained dense at this height. Individual merrnine sometimes sheltered with conspecifics of the opposite sex. Since both species utilised floristically and structurally variable vegetation, we suggest that they have the ability to cope with vegetation that has been altered by changes in fire regimes and introduced herbivores. This is particularly important for future reintroduction exercises as the results suggest that vegetation characteristics required to support these species, particularly mala, may be variable rather than limited to perceived necessary habitat types in central Australia or on islands. These results should allow future reintroduction projects to consider a wider range of release-site options during their planning phase.

The transfer of threatened animals from one location to another in order to benefit the species is a technique frequently used by animal conservation managers. However, very few of these relocations have experimentally assessed the relative merits and disadvantages of commonly used release techniques. Two species of hare-wallaby, mala (Lagorchestes hirsutus) and merrnine (Lagostrophus fasciatus), were reintroduced in August 2001 onto Peron Peninsula in Western Australia. These threatened species were reintroduced using two release strategies (soft versus hard release), and their subsequent movements and body condition were monitored using radio-telemetry and trapping.

Conservation translocations are increasingly used worldwide to prevent extinctions and support ecological restoration projects. These translocations involve a lot of uncertainty, particularly when species are introduced to ecosystems where they have not previously coexisted. Many historical translocations in Australia and globally have failed due to insufficient baseline data and inadequate post-translocation monitoring. Contemporary translocations can aim to improve translocation outcomes by increasing baseline data collection and developing robust post-release monitoring for translocated species. The development of environmental DNA (eDNA) techniques has facilitated the collection of information from environments with minimal disturbance to species. The advancement of such passive monitoring techniques has allowed for increased ability to monitor and study cryptic and rare species. The Shark Bay rufous hare-wallaby (Lagorchestes hirsutus bernieri) and the banded hare-wallaby (Lagostrophus fasciatus) were introduced to Dirk Hartog Island (DHI) from founder populations on the Bernier and Dorre islands in Shark Bay, Western Australia, as part of the Dirk Hartog Island National Park Ecological Restoration Program. Once found across large areas of south-west and central Australia, the populations on the Bernier and Dorre islands are the last natural populations of the two species due to habitat loss and predation post-European colonisation. As the rufous hare-wallaby and banded hare-wallaby have not been previously recorded on DHI, there was uncertainty regarding their successful establishment on the island and their potential interactions with each other and other species involved in the restoration program. The diets of rufous hare-wallabies and banded hare-wallabies were investigated through the DNA metabarcoding of scat samples from three islands in Shark Bay, Western Australia. This researched aimed to assess dietary overlap and the potential for resource competition between the two hare-wallaby species. Additionally, the difference in diet between the founder populations to their post-translocation diets on DHI were analysed as an indication of dietary flexibility and adaptability to environmental changes. The diets of both species of hare-wallaby were found to be broad, containing taxa from multiple plant families including invasive weeds. On DHI there was a high degree of overlap in the diets of the two species, indicating a risk of resource competition. The diets of the translocated populations differed significantly from the founder populations, which demonstrated flexible foraging behaviour and signified that rufous hare-wallabies and banded hare-wallabies are excellent candidates for future translocation projects on other islands and within mainland reserves. This thesis is the first study to define and compare the diets of the Shark Bay rufous hare-wallaby and the banded hare-wallaby using scat DNA. The understanding of diet is fundamental to ecology and an essential consideration in restoration projects involving new species interactions. The findings from this research can benefit the fulfilment of translocation success criteria related to species establishment and health targets for the new populations. By demonstrating the dietary breadth and flexibility of Shark Bay’s hare-wallabies, this thesis exemplifies the utility of scat DNA in supporting the conservation of translocated fauna.
