Abstract: To assess the direct intraoperative and postoperative costs in women undergoing total laparoscopic hysterectomy and fast-track open hysterectomy. A retrospective review of the direct hospital-related costs in a matched cohort of women undergoing total laparoscopic hysterectomy (TLH) and fast-track open hysterectomy (FTOH) at a tertiary hospital. All costs were calculated, including the cost of advanced high-energy laparoscopic devices. The effect of the learning curve on cost in laparoscopic hysterectomy was also assessed, as was the hospital case-weighted cost, which was compared with the actual cost. Fifty women were included in each arm of the study. TLH had a higher intraoperative cost, but a lower postoperative cost than FTOH (AUD$3877 vs AUD$2776 P < 0.001, AUD$3965 vs AUD$6233 P < 0.001). The total cost of TLH was not different from FTOH (AUD$7842 vs AUD$9009 P = 0.068) and after a learning curve TLH cost less than FTOH (AUD$6797 vs AUD$8647, P < 0.001). The use of high-energy devices did not impact on the cost benefit of TLH, and hospital case-weight-based funding correlated poorly with actual cost. Despite the use of fast-track recovery protocols, the cost of TLH is no different to FTOH and after a learning curve is cheaper than open hysterectomy. Judicious use of advanced energy devices does not impact on the cost, and hospital case-weight-based funding model in our hospital is inaccurate when compared to directly calculated hospital costs.

Abstract: Context Mammal–seed interactions are important for structuring vegetation communities across a erse range of ecosystems worldwide. In Australia, mammals are typically considered to be seed predators and to play insignificant roles in seed dispersal. However, very few studies have investigated endozoochorous seed dispersal in Australian species. The translocation of Australian mammals for the purposes of ecosystem restoration is increasing. Digging mammals (i.e. species that dig to obtain food or create shelter) are commonly the focus of these translocations because they are considered to be ecosystem engineers, but an understanding of their role in seed dispersal is lacking. Aims The aim of the present study was to expand the understanding of endozoochory in Australian digging mammals by determining whether seeds consumed by select species remain viable and able to germinate. Methods Scat s les were collected from five digging mammal species, known to consume seeds or fruit, across nine sites in Western and South Australia. The s les were searched for seeds, with the recovered seeds identified and tested for viability and germination capacity. Key results The abundance of intact seeds in scats was generally low, but 70% of the retrieved seeds appeared viable. Five species of seed germinated under laboratory conditions. These seeds were retrieved from bilby (Macrotis lagotis), boodie (Bettongia lesueur), golden bandicoot (Isoodon auratus) and quenda (I. fusciventer) scats. Conclusions Seeds consumed by Australian digging mammals can remain viable and germinate, indicating that digging mammals play a more important role in seed dispersal than previously considered. Implications Digging mammals have the potential to contribute to ecosystem restoration efforts through the dispersal of viable seeds, but there is also a risk that non-native species could be dispersed. These costs and benefits should be considered by practitioners when planning reintroductions of digging mammals.

Abstract: Abstract ContextTo re-establish a population of the threatened numbat (Myrmecobius fasciatus) in a newly created safe haven at Mount Gibson Wildlife Sanctuary, in the semi-arid zone of Western Australia, wild-born and captive-bred in iduals of both sexes were translocated. AimTo compare: (1) the use of refuges by wild-born numbats pre- and post-translocation, and (2) the survival and refuge use of captive-bred numbats compared with wild-sourced numbats post-translocation. MethodsMonitoring via radio-tracking facilitated the gathering of information on survival and behaviour of numbats pre- and post-translocation, and allowed a comparison of how different factors (e.g. captive-bred or wild-born male or female) influenced survival and establishment in a new environment. Key resultsThere were no significant differences in survival between sexes or between wild-born and captive-bred in iduals. However, there were some differences in behaviour between sexes and source populations. Captive-bred numbats, regardless of sex, made greater use of tree hollows as nocturnal refuges than did their wild-born counterparts. Among wild-born numbats, there was a comparatively greater use of tree hollows and logs on the ground by males at Mount Gibson than at Scotia. The use of diurnal escape refuges did not vary between sexes or between captive-bred and wild-born in iduals. ConclusionsOn the basis of the information presented here, we conclude that, in the absence of predation by mammalian predators, and with suitable release habitat, captive-bred-to-wild translocations of numbats may be as likely to succeed as are wild-to-wild translocations, at least over the first few months post-translocation. ImplicationsOptimising the size and genetic ersity of the founding population by using animals from a variety of sources may not need to be heavily constrained by concerns about the ability of captive-bred numbats to adapt to and survive life in the wild.
