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.

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.

Full text

Abstract:

Context The loss of large predators has been linked with the rise of smaller predators globally, with negative impacts on prey species (mesopredator release). Recent studies suggest that the dingo, Australia’s top terrestrial predator, inhibits predation on native mammals by the invasive red fox, and therefore reduces mammal extinctions. Feral cats also have negative effects on native mammals, but evidence that dingoes suppress cats remains equivocal. Aims We sought to examine whether dingoes might spatially or temporally suppress the activity of feral cats at a site containing the sole wild population of an endangered macropod subject to feral cat predation (the bridled nailtail wallaby). Methods We used camera traps to compare coarse and fine-scale spatial associations and overlaps in activity times of mammals between August 2009 and August 2010. Key results Dingoes and cats used the same areas, but there was evidence of higher segregation of activity times during wet months. Potential prey showed no spatial avoidance of dingoes. Peak activity times of dingoes and their major prey (the black-striped wallaby) were segregated during the wetter time of year (December to March). We did not find evidence that cats were spatially excluded from areas of high prey activity by dingoes, but there was low overlap in activity times between cats and bridled nailtail wallabies. Conclusions These findings support the contention that fear of dingoes can sometimes affect the timing of activity of feral cats. However, cats showed little spatial avoidance of dingoes at a coarse scale. Implications Control of dingoes should not be abandoned at the site, because the potential moderate benefits of reduced cat activity for this endangered and geographically restricted wallaby may not outweigh the detrimental effects of dingo predation.

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.

Full text

Abstract:

Predation by introduced foxes and cats is generally thought to be the main reason for the poor success rate of macropod reintroductions on the Australian mainland. Predator-prey theory suggests that predation may have particularly severe impacts on very small populations, especially if a more common primary prey species is present (such as the rabbit). Thus, a sufficiently large reintroduction may overcome predation and succeed where a smaller one would fail. The minimum viable population would, however, be much larger than that predicted by standard population-viability analysis. We use a simple stochastic model based upon the bridled nailtail wallaby to explore this possibility. Even very small amounts of predation (2-4 individuals per six months) can be sufficient to cause reintroductions of up to 50 animals to fail. No clear threshold population size beyond which reintroductions will succeed is evident and, for a given mean, the probability distribution of predation has a very limited impact on the success of reintroductions. In almost all circumstances, a single reintroduction of a given size is preferable to multiple reintroductions of the same total number of individuals.

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.

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:

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:

WELL defined goals are critical to successfully achieve outcomes and monitor the success of achieving them, yet conservation agencies rarely explicitly state the goals of their management activities with appropriate metrics. Here I use case studies on the conflicting conservation management focus of the Sydney Harbour National Park at North Head, the legislative impediments of bridled nailtail wallaby conservation management, the planning for broadscale habitat connectivity programmes such as Habitat 141, fire management for the conservation of the quokka and the broader Kimberley landscape, and mesopredator suppression using dingoes to highlight the problems with inappropriate conservation benchmarks. I compare these issues with activities from South Africa, India, New Zealand and Poland to illustrate the benchmarks other nations have. I conclude that Australia urgently needs an explicit conservation benchmark upon which to aim our conservation efforts and excuses of inadequate knowledge can no longer be accepted for maintaining the status quo.

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:

The responses of four species of macropodid to humans at a wildlife sanctuary were investigated experimentally. Bridled Nailtail Wallabies Onychogalea faenata, Red-necked Wallabies Macropus rufogriseus and Swamp Wallabies Wallabia bicolor all spent less time feeding, resting, grooming, interacting and more time looking up or moving in the five minutes after being approached by the researcher. Eastern Grey Kangaroos M. giganteus, Red-necked Wallabies and Bridled Nailtail Wallabies fled at shorter distances from an approaching researcher in a vehicle than from a researcher on foot. The proportion of macropodids found in grassland compared with forest was not significantly affected by a recent tour.
