II Overlap in dietry niche breadth and plant preferences with the black-striped wallaby (Macropus dorsalis) and domestic cattle."

Abstract:
Patterns of dietary selection were examined in the rare bridled nailtail wallaby (Onychogalea fraenata) and compared with those of the black-striped wallaby (Macropus dorsalis) and cattle on the Taunton Scientific Reserve in central Queensland. These two species were considered as possible competitors of 0, fraenata. The dietary niche breadth, the similarity of diet to resources, of 0. fraenata was always narrower than those of the larger species. However, the niche breadths of all species broadened significantly during the driest seasonal conditions, which accounts for the increased dietary overlaps previously reported in these conditions. An analysis of dietary preferences (electivities) showed that 0. fraenata had a high preference for herbaceous plants (forbs and malvaceous species), whereas M. dorsalis and cattle had high preference for grass. During dry conditions the preferred diet of 0. fraenata was considerably different to its actual diet, indicating that the diet was suboptimal. This pattern was not as pronounced in the other herbivores, suggesting that 0. fraenata could be at a competitive disadvantage during these conditions in its last refuge.

Abstract:
The reproduction of the endangered macropod Onychogalea fraenata was studied in captivity. O. fraenata breeds throughout the year. A post-partum oestrus was not recorded, although mating during the pouch life was observed when the pouch young were 80–92 days old. The mean length of the oestrous cycle was determined to be 36·2 days, while the mean length of a gestation period was 23·6 days. Pouch life ranged between 119 and 126 days, and the young males and females matured as early as 270 days and 136 days, respectively.

Abstract:
The bridled nailtail wallaby (Onychogalea fraenata), an endangered macropod, has been reintroduced into the wild after a captive-breeding program. As part of a management program to assess the risks to its survival O. fraenata were trapped and examined for ecto- and endoparasites. From February to September 1996, 55 wallabies from Taunton National Park, central Queensland, some trapped more than once, were visually examined for ectoparasites. The blood of 39 O. fraenata was tested for antibodies against Toxoplasma gondii and Echinococcus granulosus and a total of 82 faecal samples were examined microscopically. In addition, in a second study a complete carcase, three complete gastro-intestinal tracts, and a single stomach, obtained from various sources, including Idalia National Park, were examined for helminth parasites. The most prevalent ectoparasites were the ticksAmbylomma triguttatum and Haemaphysalis bancrofti. Other ectoparasites included four species of trombiculid mites and a louse, Heterodoxus sp. A single instance of the nippoboscid fly, Ortholfersia minuta, was found. From the serological surveys, antibodies against Toxoplasma and Echinococcus were detected in 15% and 21% respectively. No trematode or cestode eggs or protozoal cysts were found in faeces. Nematode eggs had a prevalence of 92% with a mean egg density of 500 eggs per gram. Strongyloides sp. (larvae) was the most prevalent nematode in faeces. In the postmortem study, seven nematode species (Cloacina polyxo, Hypodontus macropi, Labiostrongylus onychogale, Macropostrongyloides baylisi, Macropoxyuris sp., Rugopharynx australis and Zoniolaimus buccalis) and four cestode species (Progamotaenia bancrofti, P. zschokkei, P. abietiformis and larval E. granulosus) were found. Six of the nematode species are new host records. The presence of infection with the introduced parasites T. gondii and E. granulosus, both recognised as serious pathogens, is of management significance. Since the definitive hosts of these parasites are cats and canids respectively, control of cat, dog and dingo populations within the Park will lessen the incidence of infection with these parasites.

Abstract:
The bridled nailtail wallaby (Onychogalea fraenata) is one of Australia's rarest marsupials, persisting only in a small area in central Queensland. Its diet and those of two sympatric herbivores, the blackstriped wallaby (Macropus dorsalis) and domestic cattle (Bos taurus/indicus), were assessed by identifying plant fragments in their faeces. The diet of 0 . fraenata was diverse, consisting of herbaceous plants, grasses and browse. In good seasons the intake was biased towards forbs and other herbaceous plants. Browse was only important when vegetation availability was low. Grass could be a major part of the diet when forbs were scarse. Black-striped wallabies and cattle were largely grass eaters. When conditions were dry, browse contributed up to 16% of the diet of M. dorsalis and 10% of the diet of cattle. Dietary overlap with 0. fraenata was greatest at such times, being above 50% for both species. Potential for dietary competition was apparent and it is suggested that this may have been a factor in the decline of 0 . fraenata with the advancement of European settlement and spread of domestic stock.

Abstract:
Helminth parasites were examined from 4 Hypsiprymnodon moschatus, 18 Aepyprymnus rufescens, 13 Thylogale stigmatica, 13 Onychogalea unguifera, 2 0. fraenata, 8 Lagorchestes conspicillatus and 7 Dendrolagus lumholtzi from north and central Queensland. In all, 63 species of nematodes, ten species of cestodes and a single species of trematode were encountered. Helminth communities in H. moschatus and A. rufescens were characterised by few, highly specific parasites; D. lumholtzi similarly harboured few parasites; those of Onychogalea spp. and L. conspicillatus were more diverse and included a number of taxa shared with other macropodine hosts. The helminth community of T. stigmatica was extremely diverse and was dominated by helminths specific to Thylogale spp. The helminth communities of the various host genera showed little similarity to one another, even in the case of host species that were broadly sympatric. This lack of similarity is probably due to a mixture of factors, some related to host phylogeny and others ecological, particularly habitat type and feeding behaviour. The data presented illustrate a wider range of types of helminth communities in macropodoids than reported to date, and little evidence of exchange of parasites with rock-wallabies, Petrogale spp., examined from the same regions of Queensland.

Abstract:
Home ranges and movement schedules of sympatric bridled nailtail wallabies, Onychogalea fraenata, and black-striped wallabies, Macropus dorsalis, were studied during wet and dry seasons by radio-tracking. Home ranges of black-striped wallabies (91 ha) were much larger than those of bridled nailtail wallabies (40 ha). Home-range size differed between sexes for bridled nailtail wallabies (males, 59 ha; females, 26 ha), but not for black-striped wallabies. Intraspecific seasonal differences in home-range size were not significant. All home ranges included diurnal shelter habitat, although the preferred type of shelter habitat was different for each species. Movement schedules differed significantly between wet and dry seasons for black-striped wallabies (which made a higher frequency of longer-distance movements during the dry season than during the wet season), but not for bridled nailtail wallabies.

Full text
Abstract:
Morphological growth and qualitative development of the pouch young of captive Onychogalea fraenata are described from birth to permanent pouch emergence. Intuitively, age is a determining factor of growth and development, which precludes it from being the regressand in regression analysis. Therefore, age prediction can only be achieved by estimating expected growth for various ages and examining the confidence limits to this growth. Age values corresponding to these confidence limits are derived from the growth equations and used as limits for the ages. On the basis of these intervals the reliability of age predictions, for ages measured in different day-based units can be assessed. A statistical method is selected so that a small amount of irregularity in the frequency of measurement can be tolerated, and accounted for, in the model, as well taking into account inter-animal variation in growth parameters.

Full text
Abstract:
The parasite Toxoplasma gondii can infect any warm-blooded species; however, seroprevalence in most species remains largely unknown. In this study we examined the presence of T. gondii antibodies in captured individuals in the two remaining wild populations and one captive population of endangered bridled nailtail wallabies (Onychogalea fraenata). Samples from cats (Felis catus), rabbits (Oryctolagus cuniculus) and dogs (Canis lupus) were also taken opportunistically during invasive species control at the two wild populations. Seventy-one wallabies, sixteen cats, four rabbits, and two dogs’ blood samples were tested for T. gondii using a modified agglutination test. Half of the tested feral cats (n = 8) were seropositive and all intermediate hosts were seronegative for T. gondii antibodies. This unexpected result suggests a loss of infected individuals before capture and testing, or parasite infectivity being suppressed by Queensland’s hot, dry climate.

Abstract:
AbstractTranslocation and reintroduction are used to reduce extinction risk associated with a small population and range size in threatened mammal species. We evaluated the outcome of a reintroduction of the bridled nailtail wallaby Onychogalea fraenata to Avocet Nature Refuge, a private refuge in central Queensland, Australia. This macropod was also reintroduced to Idalia National Park in western Queensland in 1996 and occurs in one natural population in central Queensland. We estimated population growth, adult and juvenile survival, and distribution changes since the last release of O. fraenata to Avocet in 2005, and evaluated female reproductive success and health. Although animals were in good condition, population size was a tenth of that of the 1996 Idalia reintroduction reported after 3 years and, unlike at Idalia, juvenile survival at Avocet was low. The likely causes are consistent with predictors of translocation and reintroduction failures in mammals. These are predation, the small number of individuals in each release, the likely suboptimal health status of reintroduced individuals, drought, and possibly lack of dispersal from the small area of preferred habitat. The lessons of this reintroduction are that future attempts are likely to have the best chance of success if they occur in non-drought years, at sites with large, non-fragmented areas of brigalow forest, involve the release of large groups of animals together, and are accompanied by intensive, long-term baiting to control introduced predators.

Abstract:
Filarioid nematodes (Nematoda: Filarioidea) parasitic in Australasian monotremes, marsupials and murid rodents are described from three genera, Breinlia (Breinlia), Pelecitus and Sprattia. New host and geographic records are presented for 24 previously described species from these genera, a second subgenus, Breinlia (Johnstonema) and an additional three genera, Cercopithifilaria, Monanema and Pelecitus. Nine species are described as new, B. (B.) beveridgei sp. nov. from the peritoneal cavity of Macropus parryi Bennett, B. (B.) bigenera sp. nov. from the peritoneal and pleural cavities of Aepyprymnus rufescens (Gray), Onychogalea fraenata (Gould), O. unguifera (Gould) and possibly Antechinus swainsonii (Waterhouse), B. (B.) dorcopsis sp. nov. from the peritoneal cavity of Dorcopsis hageni Heller and D. luctuosa (D’Albertis), B. (B.) melomyos sp. nov. from the peritoneal cavity of Melomys cf. burtoni, B. (B.) oweni sp. nov. from the peritoneal cavity of Dactylopsila trivirgata Gray, B. (B.) presidentei sp. nov. from the peritoneal cavity of Mesembriomys gouldii (Gray), M. macrurus (Peters) and the pleural and peritoneal cavities of Conilurus penicillatus (Gould), B. (B.) tricondylus sp. nov. from the peritoneal cavity of Macropus rufogriseus banksianus (Quoy & Gaimard), B. (B.) zyzomyos sp. nov. from the peritoneal cavity of Zyzomys woodwardi (Thomas) and Z. argurus (Thomas), and Sprattia spearei sp. nov. from the lung (probably blood vessels) of Isoodon macrourus (Gould) . The female of B. (J.) woerlei from the pulmonary artery, right ventricle and lung cysts of Petrogale brachyotis (Gould) is described for the first time. Breinlia (J.) andersoni Spratt & Varughese, 1975 from the subcutaneous connective tissues of Macropus rufus (Desmarest), M. giganteus Shaw, M. robustus erubescens Sclater and Wallabia bicolor (Desmarest) is placed as a synonym of B. (J.) annulipapillata (Johnston & Mawson, 1938) from the subcutaneous connective tissues of M. dorsalis (Gray), O. fraenata and W. bicolor. In general, filarioids predominate in macropodoid hosts and in the north of Australia.

Abstract:
Blastocysts in the Hill Collection from Trichosurus vulpecula, Pefrogale penicillata, Macropus ruficollis (= M. rufogriseus), Macropus parma, Onychogalea fraenata, Bettongia gaimardi, Perameles obesula (=lsoodon obesulus), Perameles nasuta, Dasyurus viverrinus, Didelphis aurita (=D. marsupialis) and Didelphis virginiana were examined. They ranged from incomplete unilaminar blastocysts to late bilaminar blastocysts. The mode of formation of the unilaminar blastocyst appeared to be influenced by the presence or absence of the yolk mass. A unilaminar blastocyst lined by uniform protoderm cells occurred in a wide variety of marsupials. Differentiation of the unilaminar blastocyst into embryonic and extra-embryonic areas occurred at different stages of development. In macropodids and Didelphis it was found in small blastocysts soon after blastocyst completion. In dasyurids, Perameles and some other groups it was found in larger blastocysts, at least four cell generations after blastocyst completion. The first histological signs of differentiation of the unilaminar blastocyst into embryonic and extra-embryonic areas varied between different marsupials. In Didelphis, enlarged endoderm mother cells developed from the protoderm cells of one hemisphere. The protoderm cells of this hemisphere later differentiated as embryonic ectoderm and the endoderm mother cells gave rise to the primary endoderm. In D. viverrinus, bandicoots and T. vulpecula, the protoderm cells of one hemisphere differentiated simultaneously into cuboidal embryonic ectoderm and endoderm mother cells. In P. penicillata, M. ruficollis and M. parma the protoderm cells of one hemisphere proliferated to form a multilayered embryonic area which later differentiated into embryonic ectoderm and primary endoderm.

Abstract:
Sequence variation within 3 morphologically defined species of the anoplocephalid cestode genus Progamotaenia (P. ewersi, P. macropodis and P. zschokkei) was investigated using the cytochrome c oxidase subunit 1 gene. The magnitude of genetic variation detected within each morphospecies suggests that, in each instance, several cryptic species are present. Within P. ewersi, 5 genetically distict groups of cestodes were detected, 1 shared by Macropus robustus and M. parryi in Queensland, 1 in M. agilis from Queensland, 1 in Petrogale assimilis from Queensland, 1 in Macropus fuliginosus from South Australia and 1 in Wallabia bicolor from Victoria. In P. macropodis, cestodes from M. robustus from Queensland, Western Australia and the Northern Territory, M. parryi from Queensland and M. eugenii from South Australia were genetically distinct from those in Wallabia bicolor from Queensland and Victoria and from M. fuliginosus from South Australia. P. zschokkei consisted of a number of genetically distinct groups of cestodes, 1 in Lagorchestes conspicillatus and L. hirsutus from Queensland and the Northern Territory respectively, 1 in Petrogale herberti, P. assimilis and M. dorsalis from Queensland, 1 in Onychogalea fraenata from Queensland, 1 in M. agilis from Queensland and 1 in Thylogale stigmatica and T. thetis from Queensland. In general, genetic groups within each morphospecies were host specific and occurred predominantly in a particular macropodid host clade. Comparison of genetic relationships of cestodes with the phylogeny of their hosts revealed examples of colonization (P. zschokkei in M. agilis) and of host switching (P. zschokkei in M. dorsalis).

Full text
Abstract:
Diets and feeding selectivities of sympatric bridled nailtail wallabies, Onychogalea fraenata, and black- striped wallabies, Macropus dorsalis, were studied at two sites during each season on Taunton Scientific Reserve, Queensland. Bridled nailtail wallabies ate a wide variety of monocotyledon and dicotyledon species (>60) in broadly equal proportions. During dry seasons, there was a marked switch to dicotyledons, including woody browse species, which formed over 20% of material in faecal pellets. In contrast, black- striped wallabies were predominantly grazers, eating a wide variety of grasses and sedges (>65 spp.). Compared with black-striped wallabies, bridled nailtail wallabies were much more selective in their feeding, both for individual plant species and plant parts. Bridled nailtail wallabies selected against grass species, particularly during the dry season, and showed high selectivity for forbs in areas where these were scarce. Black-striped wallabies generally selected against forbs and showed random selection for grass species. Bridled nailtail wallabies showed stronger selection for food items of relatively high nutritional value (such as leaves and seedheads), and stronger selection against items of relatively high fibre content (such as grass stems) than did black-striped wallabies. Dietary overlap varied seasonally and was highest during spring and summer. The potential for inter-specific competition was highest during spring, when food resource abundance was lowest. The feeding niche of bridled nailtail wallabies is narrower than that of black-striped wallabies, indicating that the effects of competition may not be symmetric between the wallaby species. The results of this study agree with those of previous work on these species.
