Abstract: The purpose of this perspective paper and technology overview is to encourage collaboration between designers and animal carers in zoological institutions, sanctuaries, research facilities, and in soft-release scenarios for the benefit of all stakeholders, including animals, carers, managers, researchers, and visitors. We discuss the evolution of animal-centered technology (ACT), including more recent animal-centered computing to increase animal wellbeing by providing increased opportunities for choice and control for animals to gain greater self-regulation and independence. We believe this will increase animal welfare and relative freedom, while potentially improving conservation outcomes. Concurrent with the benefits to the animals, this technology may benefit human carers by increasing workplace efficiency and improving research data collection using automated animal monitoring systems. These benefits are balanced against cultural resistance to change, the imposition of greater staff training, a potential reduction in valuable animal-carer interaction, and the financial costs for technology design, acquisition, obsolescence, and maintenance. Successful applications will be discussed to demonstrate how animal-centered technology has evolved and, in some cases, to suggest future opportunities. We suggest that creative uses of animal-centered technology, based upon solid animal welfare science, has the potential for greatly increasing managed animal welfare, eventually growing from in idual animal enrichment features to facility-wide integrated animal movement systems and transitions to wildlife release and rewilding strategies.

Abstract: Bandicoots are terrestrial marsupials, endemic to Australia and Papua New Guinea. Despite drastic declines in several bandicoot species since European settlement, the northern brown bandicoot ( Isoodon macrourus ) remains common in many areas of Australia. It inhabits native environments as well as anthropogenic landscapes. This study presents comprehensive haematologic and serum biochemical results for 39 anaesthetised, clinically healthy, wild‐caught, adult northern brown bandicoots in south east Queensland, Australia. The bloodwork profile of a single animal with chronic prostatic abscessation highlights that haematology and clinical chemistry can provide useful biomarkers for identifying clinical disease in bandicoots. Comparisons of haematologic and biochemical values between sexes of the northern brown bandicoot revealed significant differences for eosinophils, alkaline phosphatase and total bilirubin. At the in idual animal level, the ranges established in this study are a guide for monitoring health and disease status however, they also have much wider applications in population health and ecological research.

Abstract: Microchip-automated devices have the potential to provide in idual free-living animals with safe nesting areas and act as a method of targeted food delivery, while excluding competitors and predators. Wildlife have been successfully trained to use such devices in captivity but never in the wild. Bringing animals into captivity may not always be feasible or appropriate due to the high cost, likely increased stress on the animals, and potential biosecurity risk. Therefore to demonstrate proof of concept that wildlife could be trained in situ to use commercially available microchip-automated devices, a brush-tailed phascogale in the wild was exposed to a microchip-automated door attached to a nest box. The phascogale was successfully trained within 15 days to use the microchip-automated door.

Abstract: The greatest limitation involved with providing enrichment and evaluating its effects on captive mammals is a lack of available staff time [Hoy et al., 2009]. One method to overcome this is through the use of automated husbandry systems to dispense enrichment to in idual animals by using implantable radio frequency microchips. An international multi-institutional survey was conducted to determine whether the personnel involved with management, research, and husbandry of captive mammals would support the development of such automated husbandry systems. The survey was also designed to establish which applications of the system would be considered to be most beneficial. Overall, there was a very high level of interest by survey respondents in adopting automated husbandry systems and all potential applications were considered beneficial to varying degrees. These results, together with the relatively low cost of installation and operation, demonstrate that in the future automated enrichment could be an important and effective means of enhancing captive animal management.

Abstract: A dynamic and innovative approach to managing the blood-consuming nematode Haemonchus contortus in goats is critical to crack dependence on veterinary anthelmintics. H. contortus management strategies have been the subject of intense research for decades, and must be selected to create a tailored, in idualized program for goat farms. Through the selection and combination of strategies from the Toolbox, an effective management program for H. contortus can be designed according to the unique conditions of each particular farm. This Toolbox investigates strategies including vaccines, bioactive forages, pasture/grazing management, behavioural management, natural immunity, FAMACHA, Refugia and strategic drenching, mineral/vitamin supplementation, copper Oxide Wire Particles (COWPs), breeding and selection/selecting resistant and resilient in iduals, biological control and anthelmintic drugs. Barbervax(®), the ground-breaking Haemonchus vaccine developed and currently commercially available on a pilot scale for sheep, is prime for trialling in goats and would be an invaluable inclusion to this Toolbox. The specialised behaviours of goats, specifically their preferences to browse a variety of plants and accompanying physiological adaptations to the consumption of secondary compounds contained in browse, have long been unappreciated and thus overlooked as a valuable, sustainable strategy for Haemonchus management. These strategies are discussed in this review as to their value for inclusion into the 'Toolbox' currently, and the future implications of ongoing research for goat producers. Combining and manipulating strategies such as browsing behaviour, pasture management, bioactive forages and identifying and treating in idual animals for haemonchosis, in addition to continuous evaluation of strategy effectiveness, is conducted using a model farm scenario. Selecting strategies from the Toolbox, with regard to their current availability, feasibility, economical cost and potential ease of implementation depending on the systems of production and their complementary nature, is the future of managing H. contortus in farmed goats internationally and maintaining the remaining efficacy of veterinary anthelmintics.

Abstract: In idually‐targeted resource supplementation for wildlife is difficult to achieve due to the challenge of excluding nontarget animals. The use of microchip‐automated technology has the potential to improve conservation outcomes globally by facilitating targeted food and nesting, offering a refuge from predators, and decreasing competition. Eight wild‐born brushtail possums ( Trichosurus vulpecula ) were trained in situ to use commercially available microchip‐automated doors installed on nest boxes placed within 5 m of their most used nesting site. Training to use the microchip‐automated door was conducted in 3 stages where the position of the door was lowered in sequential stages until it was fully closed at stage 3. Training was deemed complete at each stage when the possum entered the nest box on 2 separate nights. Seven of the 8 possums completed training. Successful training demonstrated that free‐living possums can be trained to use microchip‐automated technology in situ , thus avoiding stress, costs, and biosecurity risks associated with bringing wild animals into captivity for training. Training methods can be extrapolated to a wider range of species to assist with wildlife management from reintroductions to sustaining reduced populations. © 2021 The Wildlife Society.

Abstract: Abstract ContextSoft-release involving supplementary feeding or shelter is commonly used in wildlife reintroduction and rehabilitation projects. However, competition for nestboxes and supplementary feed, as well as predation at feed stations or nestboxes, can reduce the benefits of soft-release. The use of microchip-automated technology can potentially alleviate these concerns, by providing targeted supplementation to only the intended, microchipped animals. AimsWe aimed to train wild-caught northern brown bandicoots, Isoodon macrourus, to use microchip-automated doors to access safe refuge. MethodsBandicoots were trapped from the wild and brought to the Hidden Vale Wildlife Centre, where eight were trained to use the doors in a six-stage process, and then six were trained in a three-stage process, using a peanut butter reward. Key resultsBandicoots learned to use the doors in as few as 3 days. The duration of visits to the door generally increased during training, although the number of visits decreased. ConclusionsThe bandicoots successfully learned to use the microchip-automated doors, which shows that this technology has great potential with wildlife, particularly given the short training times required. ImplicationsThe use of these microchip-automated doors with wildlife has many potential applications, including supplementary feeding stations, nestboxes, monitoring in the wild, as well as enrichment for wild animals in captivity.

Abstract: Cats (Felis catus) are significant predators of mammals, birds, frogs and reptiles and are implicated in mammal species extinctions in Australia. Current controls fail to eradicate entire populations allowing survivors to re-establish. The use of the Mata Hari Judas (MHJ) technique, i.e., inducing prolonged oestrus using hormone implants, can enhance the eradication of remnant animals and would greatly improve conservation efforts. The hypotheses tested were that hormone implants could induce prolonged oestrus in queens (adult female cats), and that prolonging oestrus would result in sustained attractiveness to toms (adult male cats). Queens (n = 14) were randomly allocated to five treatments including a control and four treatments using hormone implants. Queens were observed daily alone and during indirect contact with a tom for 30 consecutive days. There were significant increases (p 0.001) in oestrus duration (19 to 27 days) for entire and ovariohysterectomised queens given Compudose100™ implants (1/8 or 1/4 implant). This study shows that it is possible to induce and prolong oestrus in queens using Compudose100™ implants where these queens are attractive to toms. The MHJ queen is a new tool with the potential to enhance the detection and thus the control of feral cats in remnant populations.

Abstract: Environmental enrichment of captive mammals has been steadily evolving over the past thirty years. For this process to continue, it is first necessary to define current enrichment practices and then identify the factors that limit enhancing the quality and quantity of enrichment, as well as the evaluation of its effectiveness. With the objective of obtaining this information, an international multi-institutional questionnaire survey was conducted with in iduals working with zoo-housed mammals. Results of the survey showed that regardless of how important different types of enrichment were perceived to be, if providing them was particularly time-consuming, they were not made available to captive mammals as frequently as those requiring less staff time and effort. The groups of mammals provided with enrichment most frequently received it on average fewer than four times per day, resulting in less than two hours per day spent by each animal care staff member on tasks related to enrichment. The time required for staff to complete other husbandry tasks was the factor most limiting the implementation and evaluation of enrichment. The majority of survey respondents agreed that they would provide more enrichment and carry out more evaluation of enrichment if it was manageable to do so. The results of this study support the need for greater quantity, variety, frequency, and evaluation of enrichment provided to captive mammals housed in zoos without impinging on available staff time.

Abstract: Context Recreational hunting has a long history in Australia, as in other parts of the world. However, the number, characteristics and motivations of Australian hunters have never been investigated in the same way as those in other countries where hunting occurs. Aims In this report, we aimed to systematically survey Australian recreational hunters to determine their demographic characteristics, patterns of spending and motivations. Methods Between September 2011 and June 2012, we encouraged hunters to participate in an anonymous online survey hosted by SurveyMonkey. We asked 53 questions about the hunters, their hunting patterns, expenditure on hunting and their motivations to hunt. Key results In total, 7202 hunters responded to the survey. The respondents were overwhelmingly male and 67% were aged between 31 and 60 years. Almost 34% of respondents were from Victoria, 26.7% from New South Wales and 22.0% from Queensland. Average direct expenditure on hunting was A$1835 per person per annum, whereas indirect expenditure was A$2168. Over 99% of respondents said that they would be willing to participate in pest-control activities if they had the opportunity. Conclusions There are likely to be at least 200 000 and more likely 300 000 recreational hunters in Australia and they spend in excess of A$1 billion dollars annually on hunting. Almost all of these hunters are willing to participate in direct wildlife management activities, such as pest control. Implications The Australian recreational hunting community is large, active and willing to spend large amounts of money on hunting. Their activities need to be understood and participants engaged by wildlife managers so as to obtain the best outcomes for wildlife management in Australia.

Abstract: Commercially available microchip-automated devices for companion animals also have potential application with captive wildlife. To explore this potential, a captive bridled nailtail wallaby was trained to use a SureFlap Microchip Pet Door. Throughout the 62 day study the wallaby's interactions with the door increased in frequency and intensity, culminating in the repeated use of the microchip-automated door. This was the first record of any captive macropod being trained to use a microchip-automated device and demonstrates proof-of-concept that captive macropods can successfully utilize commercially available microchip-automated devices. Further research is recommended to develop methodology and evaluation techniques for training captive macropods while also exploring intra- and inter-species variations in responses.

Abstract: The brush-tailed rock-wallaby (Petrogale penicillata) is a nocturnal refuge dependent herbivore that can be found from south-east Queensland to East Gippsland in Victoria. Brush-tailed rock-wallaby colonies are situated in many different habitat types, and refuge within this habitat is important for their survival. Dingoes coexist with P. penicillata and are perceived to be a threat. This study aimed to determine the link between habitat and P. penicillata behaviour and their interaction with predators. Three P. penicillata colonies were studied within the Little Liverpool Range, Queensland. Images of P. penicillata and dingoes from camera traps were analysed for daily activity patterns and activity overlap between species. Dingo scats were collected and analysed to determine predation. The results indicated that different habitat types change the perceived predation risk and corresponding activity patterns of P. penicillata. Predation risk impacted foraging behaviour, with rock-wallabies in exposed habitat types exhibiting greater predator avoidance behaviours than those in more protected habitat types. The results indicate that brush-tailed rock-wallabies modified their activity patterns according to different habitat types to reduce their risk of predation.

Abstract: Microchip-automated feeders and doors allow in idualised access to supplementary food and shelter during soft-release of wildlife. A wild-caught brush-tailed phascogale was used to test whether a wild animal could be trained to use microchip-automated devices. The phascogale was trained to use each device in less than a month.
