Abstract: The performance of ozonation in wastewater depends on water quality and the ability to form hydroxyl radicals (·OH) to meet disinfection or contaminant transformation objectives. Since there are no on-line methods to assess ozone and ·OH exposure in wastewater, many agencies are now embracing indicator frameworks and surrogate monitoring for regulatory compliance. Two of the most promising surrogate parameters for ozone-based treatment of secondary and tertiary wastewater effluents are differential UV(254) absorbance (ΔUV(254)) and total fluorescence (ΔTF). In the current study, empirical correlations for ΔUV(254) and ΔTF were developed for the oxidation of 18 trace organic contaminants (TOrCs), including 1,4-dioxane, atenolol, atrazine, bisphenol A, carbamazepine, diclofenac, gemfibrozil, ibuprofen, meprobamate, naproxen, N,N-diethyl-meta-toluamide (DEET), para-chlorobenzoic acid (pCBA), phenytoin, primidone, sulfamethoxazole, triclosan, trimethoprim, and tris-(2-chloroethyl)-phosphate (TCEP) (R(2) = 0.50-0.83) and the inactivation of three microbial surrogates, including Escherichia coli, MS2, and Bacillus subtilis spores (R(2) = 0.46-0.78). Nine wastewaters were tested in laboratory systems, and eight wastewaters were evaluated at pilot- and full-scale. A predictive model for OH exposure based on ΔUV(254) or ΔTF was also proposed.

Abstract: Understanding the impacts of roads on wildlife and the natural environment is of increasing importance. Macropods (mostly kangaroos and wallabies) are a erse and widespread taxon in Australia that has been significantly affected by the presence of roads in various ways. We reviewed the available literature on macropods and roads, assessing 60 scientific journal articles, reports and theses. Studies on road mortalities were the most prevalent (n = 29, with 12 on macropods only), revealing both spatial and temporal patterns in occurrence. Behavioural studies in relation to the road environment are limited (n = 2) yet could help our understanding of patterns of road-kill and other impacts. Some macropod populations are critically affected by the presence of roads (e.g. brush-tailed rock-wallaby, Petrogale penicillata) due to either proportionately high road mortalities and/or population fragmentation, and may face continued decline unless effective road-mitigation measures are implemented. Investigations of various types of road mitigation focussed on wildlife-exclusion fencing and road crossing structures as the most effective option, although the high cost of these measures appears to limit their implementation. Further research into several areas was identified, particularly on species where severe road impacts are likely to result in population declines.

Abstract: Behaviour of free-ranging megapode hatchlings is best studied by radio-tracking because these superprecocial birds receive no parental care and therefore cannot be followed by the tracking of their parents. In preparation for a study of the behaviour of free-ranging Australian brush-turkey (Alectura lathami) chicks, we investigated methods of transmitter attachment and assessed possible effects on the behaviour and condition of captive hatchlings. We attached transmitters to 2–10-day-old chicks by gluing the tag to the skin on the back with eyelash-glue. Rapid-setting glues (such as Superglue), often used for gluing transmitters to other birds, were found to damage the skin and were not used. Retention of transmitters was 3–4 weeks. We detected no difference in the time spent preening, feeding, resting and moving between captive radio-tagged chicks and a control group. Flight of tagged chicks was not hindered by the radio-package and tagged chicks gained mass at the same rate as the control group. Free-ranging chicks with radio-tags showed no obvious signs of a negative effect of the transmitters on behaviour: they flew without obvious impediment, walked more than 100 m per day and, except for a single chick, did not become entangled in vegetation. We recommend our attachment method for studies of precocial and superprecocial chicks where transmitter attachment is deemed essential.

Abstract: The use of animal‐borne devices in wildlife studies is increasing due to the miniaturization of sensors and reductions in component costs. Retrieval of animal‐borne devices is often advantageous for several reasons, including data retrieval and animal welfare considerations however, commercially available drop‐off units are often prohibitively expensive and/or unreliable. Here, we present ‘OpenDropOff’, an open‐source, low‐cost electronic drop‐off unit for remotely detaching animal‐borne sensors from in iduals. OpenDropOff devices function by using heat, produced by running an electrical current through resistance wire (nichrome), to melt nylon (e.g. fishing) line, detaching sensors from animals at or after a pre‐determined time. OpenDropOff can be constructed using commercially available components (costing USD $15 in total approximately 10% or less of many commercially available drop‐off units) and can be customized to fit project‐ and species‐specific needs. Fourteen OpenDropOff devices have been field deployed on koalas ( Phascolarctos cinereus ) ( n = 11), sw wallaby ( Wallabia bicolor ) ( n = 1), Australian brush turkey ( Alectura lathami ) ( n = 1) and Australian white ibis ( Threskiornis molucca ) ( n = 1), with the only detachment failure occurring after a device was damaged during the koala’s unrelated death. OpenDropOff devices provide a wider range of researchers with a reliable, cost‐effective tool for detaching animal‐borne sensors. Their use could allow researchers to more efficiently allocate project resources, and their flexibility provides an opportunity to mitigate animal welfare concerns surrounding the use of animal‐borne devices.

Abstract: It is now well established that men and women often differ significantly in their attitudes and responses to workplace situations, challenges and policies. The aim of this study was to examine the effect of gender on perceptions and priorities held by Australasian wildlife managers. Data were collected via a questionnaire distributed during December 2002 – February 2003 to members of the Australasian Wildlife Management Society (AWMS) and registrants of the 2002 AWMS annual conference. The results show that there are now significantly more female AWMS members than there were in the early 1990s, a possible indication of a change in the wider wildlife management profession in Australasia. Consistent with previous research, male respondents held different views from female respondents about wildlife and wildlife management. In particular, male respondents were significantly more likely to express the ‘management/consumptive use of wildlife’ perspective than female respondents. Interestingly, this gap was observed only in the 18–30-year age category. The paper examines what these differences might mean for the future of wildlife management in Australasia.

Abstract: Although fauna crossing structures have been installed throughout the world, most studies have been of underpasses and overpasses. Canopy-bridges, however, have received much less attention. In addition, although exclusion fencing is used extensively, its effectiveness has rarely been assessed. Since 2015, Moreton Bay Regional Council (MBRC), in southern Queensland, Australia, has installed various mitigation structures at 21 sites. This study compared the use of different designs of canopy-bridge and assessed the effectiveness of exclusion fencing via camera monitoring and roadkill records. A total of 3151 detections of five arboreal species were made on the canopy-bridges at an average of 0.51 crossings per day for both rope cages and rope ladders and 0.64 on rope cages and 0.77 on rope ladders when a poorly used bridge of each type was excluded. A single aluminium ladder had 33 crossings (0.15 crossings per day) but was available for only a short time. Roadkill rates of all species declined by 84% at sites with underpasses and fencing compared to 93% at sites without, but only 39% at control sites. This may be due to the canopy-bridges or the addition of complementary infrastructure, such as signage, pavement stencilling and driver awareness.

Abstract: Although frequently reported from within the Brisbane city boundaries, the range of the Australian brush-turkey, Alectura lathami, was limited mainly to forested areas adjacent to suburban areas. Since the early 1970s, however, the species' presence in the suburbs has increased steadily and it is now common in many suburbs. Destruction and disruption of gardens during the construction of incubation mounds has led to a significant conflict with householders. This study found the species to be most abundant in suburbs adjacent to forest reserves and major watercourses. A number of extremely isolated populations were also identified. Although suburban mounds contained similar numbers of eggs as mounds from the wild, suburban mounds were more prone to failure, probably due to the use of inappropriate mound materials. Despite some evidence of increasing spread within the suburbs, the long-term survival of the species is seriously threatened by hatchling predation and continued loss of habitat.

Abstract: Some birds don't incubate their eggs using the warmth of their bodies. The megapodes have evolved a markedly different method of incubation. By making use of environmental heat, adult megapodes are emancipated from most of the usual constraints to reproductive success associated with parental care. Consequences of this unique incubation method are evident in all aspects of megapode development and behaviour. Recently, renewed interest in these birds from a number of disciplines has led to significant advances, especially in aspects associated with reproduction. Both eggs and embryos exhibit remarkable adaptations to the physiologically stressful incubation environment. The use of various types of incubation heat may also shape the mating systems of the species involved.

Abstract: Many koala populations around Australia are in serious decline, with a substantial component of this decline in some Southeast Queensland populations attributed to the impact of Chlamydia. A Chlamydia vaccine for koalas is in development and has shown promise in early trials. This study contributes to implementation preparedness by simulating vaccination strategies designed to reverse population decline and by identifying which age and sex category it would be most effective to target. We used field data to inform the development and parameterisation of an in idual-based stochastic simulation model of a koala population endemic with Chlamydia. The model took into account transmission, morbidity and mortality caused by Chlamydia infections. We calibrated the model to characteristics of typical Southeast Queensland koala populations. As there is uncertainty about the effectiveness of the vaccine in real-world settings, a variety of potential vaccine efficacies, half-lives and dosing schedules were simulated. Assuming other threats remain constant, it is expected that current population declines could be reversed in around 5-6 years if female koalas aged 1-2 years are targeted, average vaccine protective efficacy is 75%, and vaccine coverage is around 10% per year. At lower vaccine efficacies the immunological effects of boosting become important: at 45% vaccine efficacy population decline is predicted to reverse in 6 years under optimistic boosting assumptions but in 9 years under pessimistic boosting assumptions. Terminating a successful vaccination programme at 5 years would lead to a rise in Chlamydia prevalence towards pre-vaccination levels. For a range of vaccine efficacy levels it is projected that population decline due to endemic Chlamydia can be reversed under realistic dosing schedules, potentially in just 5 years. However, a vaccination programme might need to continue indefinitely in order to maintain Chlamydia prevalence at a sufficiently low level for population growth to continue.

Abstract: Infection is an important source of mortality for avian embryos but parental behaviors and eggs themselves can provide a network of antimicrobial defenses. Mound builders (Aves: Megapodiidae) are unique among birds in that they produce heat for developing embryos not by sitting on eggs but by burying them in carefully tended mounds of soil and microbially decomposing vegetation. The low infection rate of eggs of one species in particular, the Australian brush-turkey (Alectura lathami) suggests that they possess strong defensive mechanisms. To identify some of these mechanisms we first quantified antimicrobial albumen proteins and characterized eggshell structure, finding that albumen was not unusually antimicrobial, but that eggshell cuticle was composed of nanometer-sized calcite spheres. Experimental tests revealed that these modified eggshells were significantly more hydrophobic and better at preventing bacterial attachment and penetration into the egg contents than chicken eggs. Our results suggest that these mechanisms may contribute to the antimicrobial defense system of these eggs, and may provide inspiration for new biomimetic anti-fouling surfaces.

Abstract: The suburban bird community of Wagga Wagga, N.S.W., was surveyed during December 1978-January 1979 and May 1979, at nine sites selected to cover all ages of residential areas from predevelopment to oldest suburbs and to demonstrate how the bird community will change with time in response to changing habitat. Non-residential sites were also s led. Sites were censused by foot transect. House sparrows which were present in all sites, were the first species to colonize new residential areas and made up over 95% of the in idual count of four sites Of native species, 40% were found in undeveloped sites only. The population density of undeveloped sites was only half that of developed sites, but the greatest species ersity was found in undeveloped sites and the lowest in the most altered sites. There was strong evidence for a steady linear increase in numbers of in iduals, numbers of species, biomass and population density with increasing age of residential area, reaching a peak at about 30 years.

Abstract: Radio‐frequency identification (RFID) tags represent some of the smallest animal‐borne technologies available. They are frequently used for understanding fine‐scale associations between animals and their environments. However, currently available devices are often prohibitively expensive or difficult to customise. We present ‘WildWID’, an open‐source radio‐frequency identification system that can be used for detecting encounters between tags and loggers and/or integrated into more advanced experimental set‐ups for triggering audio or visual playbacks following the detection of RFID tag codes. WildWID systems can be made using commercially available components (costing ~$20 USD for tags and ~$60 for loggers) and can be customised to fit project and species‐specific needs. WildWID tags have been deployed on a range of species including koalas Phascolarctos cinereus , lions Panthera leo and shy albatross Thalassarche cauta for a range of research topics, including the assessment of road‐crossing structures and species' responses to intraspecific competitors. WildWID is a cost‐effective RFID system that can increase the accessibility of this technology for a wider range of researchers and study questions. Its use provides researchers with opportunities to mitigate ethical concerns, for ex le, by customising systems for species‐specific conditions, and its customisability extends the range of applications where RFID systems can be used by field biologists.

Abstract: Most metals show elastic strain limits well below 1%, beyond which permanent plastic deformation occurs. Metal nanowires can be elastically stretched to much higher strains, on the order of 4 to 7%. However, when placed inside a metal matrix to form a composite, these nanowires can no longer be stretched to the same extent, even when the nanowires are well distributed and show good bonding with the matrix. Hao et al. (p. 1191 see the Perspective by Zhou ) used a shape memory alloy as the matrix material to produce a much better (more elastic) composite.

Abstract: Consumer satisfaction and preference can be integral in influencing and solidifying change in user-driven industries such as tourism. High satisfaction rates are imperative to the continual success of a venue as satisfaction determines the likelihood of repeat business and positive recommendations to friends, family and online review forums. Tourist preference for ecocentric tourism venues, over anthropocentric ones, appears to be increasing in elephant tourism venues (ETVs) in Thailand. To explore this, we visited twelve ETVs in Chiang Mai, Thailand, and compared the preferences and satisfaction of tourists who visited riding and non-riding venues toward the use of captive elephants in an entertainment setting. We found that tourists visited riding and non-riding ETVs for similar reasons, primarily due to recommendations from friends and reviews, and because the venue had a good reputation. Tourist preference for higher welfare standards was observed at venues where participants directly observed poor treatment of the elephants. Tourist satisfaction may be impacted by higher elephant welfare standards therefore, tourists have the ability to influence the elephant tourism industry by demanding better living conditions for elephants and only financially supporting ETVs with higher welfare standards.

Abstract: Megapodes meet conspecifics at an unpredictable age, and it is unknown how their social behavior develops under such conditions. The authors induced encounters between 2-day-old socially naive hatchlings and up to 49-day-old chicks of the Australian brush-turkey (Alectura lathami) in a large outdoor aviary. All social behavior patterns found in older chicks were present in hatchlings and did not change in form or the frequency in which they occurred thereafer the frequency of calling was the only feature that changed significantly with age. Chicks stayed only 0.3-2.0 m (medians) apart and synchronized their feeding activity from the age of 20 days. These results indicate that megapode chicks show social behavior without social experience and that this requires no postnatal leaning.

Abstract: The impact of roads on local bio ersity is a major issue associated with urbanisation. A major arterial road in the southern suburbs of Brisbane, south-east Queensland, was upgraded in 2004–05 from two to four lanes. In an attempt to minimise the impact of the larger road on local wildlife populations, a range of fauna crossing structures were constructed at the site. Monitoring of road-kill was undertaken for 4 months before construction and after the completion of construction. Assessment of the use of two underpasses and a large overpass (‘land-bridge’) started 6 months after construction using sand tracking in underpasses and scat s ling on the land-bridge. An initial 26-week period of intensive monitoring was undertaken from August 2005 to February 2006 followed by monthly monitoring from June 2006 to June 2007. On average, 1–5 tracks per day were detected in the underpasses at the start of the survey, increasing steadily to ~42 tracks per day by February 2006. The monthly survey showed regular use of the underpasses by a wide range of species and species-groups, the most abundant being ‘rodents’, most likely Rattus species, both native and introduced. The land-bridge was also used continuously by three species of macropod (red-necked wallaby, Macropus rufogriseus sw wallaby, Wallabia bicolor and eastern grey kangaroo, Macropus giganteus) with brown hare (Lepus capensis) becoming increasingly common in summer 2006. The exclusion fencing was extremely effective in preventing most road-kill, at least of larger species, except following human-related breaches in the fence.

Abstract: Occasionally, interactions between dingoes (Canis dingo) and people on Fraser Island result in serious injury, and, in one case, death. The risk to human safety from such interactions may be mitigated if people could carry a suitably defensive repellent, similar in principle to bear (Ursus spp.) repellent spray advocated in North America. In the first step towards searching for suitable stimuli that might be used as repellents with dingoes, we observed the responses of nine dingoes to three stimuli during interactions with a researcher on Fraser Island. Two treatment stimuli were assumed to be potentially aversive (an air horn blast and a water jet from a motorised water pistol), and one was considered unlikely to be aversive and therefore suitable as a control (a whistle being blown). Responses to the stimuli varied. All nine dingoes were initially presented with the whistle however, only one adult male responded as if the whistle was aversive. Seven of the nine dingoes were later presented with a whistle and treatment stimuli together. None of the seven dingoes were repelled during any air horn treatment trials however, six of seven dingoes (all juveniles) were repelled by the water pistol stimulus. Although a water pistol was effective at repelling young dingoes on many occasions, responses between in iduals were inconsistent. Results from this pilot study suggest that a water pistol stimulus may offer some protection as a repellent to close approaches by young dingoes, particularly if enhanced with a mild irritant.

Abstract: Obtaining superior physical properties for ferroic materials by manipulating the phase transitions is a key concern in solid state physics. Here, we investigated the dielectric permittivity, piezoelectric coefficient d33, storage modulus, and crystal symmetry of (1-x)Ba(Ti0.8Zr0.2)O3-x(Ba1−yCay)TiO3 (BZT-xBCyT) systems to demonstrate the gradual evolution process from successive phase transitions in BaTiO3 to the morphotropic phase boundary (MPB) regime in BZT-xBC0.3T. Furthermore, we analysed with a Landau-type theoretical model to show that the high field-sensitive response (dielectric permittivity) originates from a small polarization anisotropy and low energy barrier at the quadruple point. Together, the intermediate orthorhombic phase regime and the tetragonal-orthorhombic and orthorhombic-rhombohedral phase boundaries constitute the MPB. Our work not only reconciles the arguments regarding whether the structural state around the MPB corresponds to a single-phase regime or a multiple-phase-coexistence regime but also suggests an effective method to design high-performance functional ferroic materials by tailoring the successive phase transitions.

Abstract: Daylight saving time (DST) could reduce collisions with wildlife by changing the timing of commuter traffic relative to the behaviour of nocturnal animals. To test this idea, we tracked wild koalas ( Phascolarctos cinereus ) in southeast Queensland, where koalas have declined by 80% in the last 20 years, and compared their movements with traffic patterns along roads where they are often killed. Using a simple model, we found that DST could decrease collisions with koalas by 8% on weekdays and 11% at weekends, simply by shifting the timing of traffic relative to darkness. Wildlife conservation and road safety should become part of the debate on DST.

Abstract: Australian magpies are the cause of a major wildlife-management conflict in suburban areas throughout Australia. Mitigation of this conflict is becoming increasingly difficult in some locations because of community opposition to the destruction of the birds involved, which remains a common management solution of many wildlife agencies. Translocation – the capture and release elsewhere – of offending birds has been advocated but never seriously evaluated. This study aimed to assess the effectiveness of translocation as a means of eliminating magpie attacks. We also attempted to assess the impact of the approach on both the translocated birds and those remaining in the territory. A total of 20 aggressive magpies, all males, were captured and released at distances 17–150 km from the place of capture. Most birds released more than 30 km away were not seen again two birds released less than 30 km away returned quickly and were recaptured. A single bird re-established itself on its original territory several months after capture. In many cases, new males had replaced the captured birds within days. There was no evidence of negative behavioural interactions between these males and the resident females or chicks. While the technique is effective in reducing the human–magpie conflict at specific locations, our lack of knowledge of the fate of translocated males, as well as several other issues, suggests that this approach be used only in extreme circumstances.

Abstract: This study investigated the potential for wildlife feeding to artificially increase population densities of the Australian brush-turkey, Alectura lathami and assessed the indirect adverse effects that this may have on surrounding forest floor vegetation. Census counts and observations of feeding activity conducted in recreation areas of Australia's Gold Coast hinterland confirmed that brush-turkey population densities were significantly elevated by the provision of food by humans. Brush-turkey densities were high at sites where birds are actively fed, moderate at sites where birds feed opportunistically and low at sites where humans have negligible impact on local food availability. Brush-turkeys caused significant environmental impact at sites where their population densities have been substantially elevated by active feeding. Across all sites, increases in brush-turkey density were accompanied by a significant decline in ground cover, leaf litter weight, seed density and seedling density. Natural environmental variables such as gradient, vegetation type and canopy cover did not explain the observed impacts. The impacts were consistent with those described in tr ling studies and suggest that at high density, even small animals can have significant tr ling impacts on their local environment. This study demonstrates that wildlife feeding can have detrimental impacts on the integrity of local environments and recommends greater consideration of small animals and their potential indirect impacts when regulating wildlife feeding in National Parks and other nature conservation areas.

Abstract: Habitat use by birds in suburbs of Brisbane, Queensland was studied during winter, at sites with relatively similar habitat features near to (0.25-0.5km) and far from (2-3km) a eucalypt forest. Variation in other factors was restricted. Distance from native forest was found to have little influence on abundance of birds in suburban habitats. House sparrows and willie wagtails were relatively more abundant at the far sites. Most of the more common forest-dwelling species were not common in either near or far suburbs. There was little similarity in relative abundance of bird species between the forest and either the near or far suburbs. A similarity in species ersity and positive correlations in species abundance between near and far sites indicate that most species are either forest or suburb 'specialists'. Native birds were more selective in their choice of plant category than introduced birds, and had a high probability of using certain native and exotic plant species, and a lower probability of using others. Although generally more abundant, introduced birds did not have a high probability of using any plant genus or type. Birds in the area studied are probably altering their patterns of habitat use in response to changes in food availability.

Abstract: Within the expanding city of Brisbane in south-east Queensland, numerous fragments of native and regrowth vegetation are scattered across the largely urbanised landscape. These fragments provide refuge to a great ersity of native wildlife, and provide residents with the opportunity to experience nature on their doorstep. To assess the ersity and abundance of this wildlife, recent changes in these parameters, and the value of wildlife and bushland fragments to residents of Brisbane, a questionnaire survey was distributed to 300 households each located adjacent to one of 38 urban bushland fragments. A total of 172 surveys (57%) were returned, producing 768 records of 83 fauna species, dominated by birds and mammals bandicoots were widely reported from the 38 fragments. Several historical records provided evidence of recent local extinctions within fragments, highlighting the continuing declines in various species of native wildlife within Brisbane. Several human–wildlife conflicts were identified, but overall residents were tolerant of such conflicts. Bandicoots were disliked by a small minority (3%) of residents owing to the holes they dig in lawns and gardens in search of food, and their potential as vectors of ticks. Most respondents expressed an appreciation for the presence of native wildlife (96%) and bushland fragments (97%) in their local area, emphasising the importance of incorporating human dimension values into the management of this urban bio ersity.

Abstract: The ability to predict the frequency with which koalas (Phascolarctos cinereus) cross roads is an important step in developing mitigation strategies aimed at maintaining metapopulation viability for this species. In south-east Queensland, Australia, rapid urban development, including fragmentation and vehicle-related mortality, has contributed to a dramatic decline in local koala populations. Assessment of wildlife crossing structures that mitigates the impact of roads demonstrates these to be beneficial for many species. However, building enough structures to enable animals to move freely across impacted landscapes may be prohibitive in complex urban landscapes. The focus for this study was to consider the role of differing characteristics for species at risk. We examined the frequency of road crossings by in idual koalas among six subpopulations in south-east Queensland. We explored the influence of potential predictor variables including: age, sex, and distance from roads. We established that road crossings were limited to a subset of in iduals, with only 18 of 51 (~35%) koalas studied ever crossing a road. We found that koalas were disproportionately more likely to cross a road if they had initially been found within a distance of 100 m of that road. Males were more likely to cross roads than females, as were koalas aged less than five years. We suggest that successful wildlife road mitigation can be improved by better understanding the road-crossing behaviour of species such as the koala.

Abstract: Context Vehicle-strike has been identified as a key threatening process for koala (Phascolarctos cinereus) survival and persistence in Australia. Roads and traffic act as barriers to koala movement and can impact dispersal and metapopulation dynamics. Given the high cost of wildlife mitigation structures such as purpose-built fauna-specific underpasses or overpasses (eco-passages), road construction and management agencies are constantly seeking cost-effective strategies that facilitate safe passage for fauna across roads. Here we report on an array of detection methods trialled to verify use of retrofitted road infrastructure (existing water culverts or bridge underpasses) by in idual koalas in fragmented urban landscapes in south-east Queensland. Aims The study examined whether the retrofitting of existing road structures at six sites facilitated safe passage for koalas across roads. Our primary objective was to record utilisation of retrofitted infrastructure at the level of the in idual. Methods We used a combination of existing monitoring methods such as GPS/VHF collars, camera traps, sand plots, and RFID tags, along with a newly developed animal-borne wireless identification (WID) tag and datalogging system, specifically designed for this project, to realise the study aims. Key results We were able to verify 130 crossings by koalas involving a retrofitted structure or a road surface over a 30-month period by using correlated data from complementary methods. We noted that crossings were generally uncommon and mostly undertaken by only a subset of our tagged in iduals at each site (21% overall). Conclusions An important element of this study was that crossing events could be accurately determined at the level of the in idual. This allowed for detailed assessment of eco-passage usage, rather than the more usual approach of simply recording species’ presence. Implications This study underscores the value of identifying the constraints of each in idual monitoring method in relation to site conditions. It also highlights the benefits of contingency planning to limit data loss (i.e. using more than one method to collect data). We suggest an approach that uses complementary monitoring methods has significant advantages for researchers, particularly with reference to improving understanding of whether eco-passages are meeting their prescribed conservation goals.

Abstract: K’gari (Fraser Island) offers a rare opportunity for people to observe and encounter wild dingoes. Occasionally, however, such encounters can entail dingoes acting in a threatening or aggressive manner towards people, resulting in human injury and, in one tragic case, death. A suite of approaches aimed at minimising the risk to human safety posed by dingoes have been implemented on the island, including fencing, island-wide warning signage, and regulations against feeding. Despite such measures, negative encounters continue, and in cases where dingoes are deemed to pose an unacceptable risk, they are usually destroyed. In searching for non-lethal management alternatives, attempts have been made to modify undesirable dingo behaviour through aversive conditioning, but results to date have either been mixed or largely disappointing. Here we review a wide array of research that has utilised aversive stimuli in an effort to modify and manage the behaviour of wild animals, with a particular focus on related predators such as coyotes and wolves. We identified eight major categories of experimental research: conditioned taste aversion/avoidance (CTA), electric fencing, fladry, chemical repellents, fear-evoking stimuli, physical repellents, aversive collars/devices and hard release procedures. We then outline each of these categories in more detail, complete with pertinent ex les of successes and failures as well as advantages and disadvantages. We conclude that some approaches offer promise within three main areas of incident mitigation experimentation: dingo exclusion (e.g. electric fencing), personal protection (mild chemical irritant sprays, sturdy umbrellas) and remedial aversive conditioning (e.g. shock collars). Other approaches, such as CTA and sublethal projectiles are not recommended. Like any approach, aversive conditioning is not a panacea, but it does offer promise in filling gaps in current management and as an alternative to lethal control.

Abstract: Top-predators play stabilising roles in island food webs, including Fraser Island, Australia. Subsidising generalist predators with human-sourced food could disrupt this balance, but has been proposed to improve the overall health of the island’s dingo ( Canis lupus dingo ) population, which is allegedly ‘starving’ or in ‘poor condition’. We assess this hypothesis by describing the diet and health of dingoes on Fraser Island from datasets collected between 2001 and 2015. Medium-sized mammals (such as bandicoots) and fish were the most common food items detected in dingo scat records. Stomach contents records revealed additional information on diet, such as the occurrence of human-sourced foods. Trail camera records highlighted dingo utilisation of stranded marine fauna, particularly turtles and whales. Mean adult body weights were higher than the national average, body condition scores and abundant-excessive fat reserves indicated a generally ideal-heavy physical condition, and parasite loads were low and comparable to other dingo populations. These data do not support hypotheses that Fraser Island dingoes have restricted diets or are in poor physical condition. Rather, they indicate that dingoes on Fraser Island are capable of exploiting a erse array of food sources which contributes to the vast majority of dingoes being of good-excellent physical condition.

Abstract: Bird feeding is essentially a massive global supplementary feeding experiment, yet few studies have attempted to explore its ecological effects. In this study we use an in situ experimental approach to investigate the impacts of bird feeding on the structure of local bird assemblages. We present vital evidence that bird feeding contributes to the bird community patterns we observe in urban areas. In particular, the study demonstrates that common feeding practices can encourage higher densities of introduced birds, with potential negative consequences for native birds.

Abstract: In contrast to several species of cetaceans and primates, behavioural responses to dead conspecifics have rarely been reported in wild canids. Here we provide details of the responses of an adult female and littermates to a dying and subsequently dead pup, including what appeared to be four instances of transport of the deceased pup by the mother over a two-day period, one of which was directly observed and filmed. We tentatively propose that, in the absence of any evidence of consumption of the pup, its transport by the mother could be interpreted as care-giving behaviour emanating from an enduring mother-infant bond, in a similar vein to what has been suggested for several other species exhibiting such behaviour.

Abstract: The selection of methods for wildlife surveys is a decision that will influence the accuracy and comprehensiveness of survey outcomes. The choice of methods is commonly based on the species of interest, yet is often limited by the project budget. Although several studies have investigated the effectiveness of various survey techniques for detecting terrestrial mammal and reptile species, none have provided a quantitative analysis of the costs associated with different methods. We compare the detection success and cost efficiency of cage traps, Elliott traps, pit-fall traps, hair funnels, direct observation, and scat detection/analysis for detecting the occurrence of terrestrial reptile and small mammal species in urban bushland remnants of Brisbane City, Queensland, Australia. Cage traps and Elliott traps coupled with hair funnels were the most cost-effective methods for detecting the highest number of ground-dwelling mammal species. Pit-fall traps and direct observations were the most cost-effective methods for maximising the number of reptile species identified. All methods made a contribution to overall detection success by detecting at least one species not detected by any other method. This suggests that a combination of at least two complementary methods will provide the most successful and cost-efficient detection of reptile and mammal species in urban forest remnants. Future studies should explicitly test these findings and examine efficient trapping combinations across different habitat types and for other fauna groups.

Abstract: The feeding ecology of the cockatiel Nymphicus hollandicus was studied in a grain-growing district near Moree, in northern New South Wales, between August 1980 and June 1982, by direct observations and monthly collections of birds in feeding flocks. Cockatiels fed from the ground, on fallen seed or by felling stems, and, when feeding on sorghum and sunflowers, while perched on the seed heads. The mean size of a feeding flock was 27 large flocks of more than 100 birds were formed only during periods of limited food supply. Cockatiels showed a clear preference for sorghum over sunflowers, and when on cereals they appeared to prefer softer, younger seed to harder, mature seed. Overall they fed on 29 seed types, including four grain-crops, 17 grasses and eight non-grass ground plants. Sorghum was by far the most important food item, making up almost 60% of total crop contents sunflower made up only 6% of crop contents, and grasses 19.3% 90% of this last was contributed by Phalarisparadoxa and Setar~a sp. Some management implications, based on apparent food preferences, are discussed.

Abstract: Attacks on humans by Australian magpies (Gymnorhina tibicen) cause a significant human–wildlife conflict in suburban environments throughout Australia. Community opposition to lethal control methods generally has, in part, led to an increase in the use of translocation as an alternative. We assessed the effectiveness and implications of using this approach in the management of aggressive magpie in south-eastern Queensland during 1999 and 2000. A total of 968 (1999) and 707 (2000) magpies were reported by the public, of which 39–45% were able to be investigated by a two-person team working three days per week. A total of 141 magpies were translocated, 31.7% of all birds investigated. Of these, only five (3.5%) returned to the place of capture, and 22 (15.6%) were resighted elsewhere there was no evidence of 'homing'. Only three translocated birds were subsequently reported as being aggressive towards humans. While extremely effective in reducing the conflict locally, we caution against the indiscriminate use of this method, and suggest that it be seen as one of many options available to wildlife managers.

Abstract: The piezoelectric activity of lead-free Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3 (BZT-xBCT) ceramics has been investigated as a function of composition by using Rayleigh analysis under subswitching-electric-field in combination with large-electric-field strain measurement. The result shows that the intrinsic piezoelectric response exhibits peak values in the vicinity of composition-induced R (rhombohedral)-MPB (morphotropic phase boundary) and MPB-T (tetragonal) phase transitions, but being much less than total d33 value. On the other hand, the extrinsic piezoelectric response, especially the one associated with reversible domain wall motion, has been greatly enhanced in the phase instability regime. Our results indicate that the extrinsic piezoelectric activity is the major contributor to the high piezoelectricity in BZT-xBCT ceramics.

Abstract: Although attacks on humans by Australian magpies (Gymnorhina tibicen) are a source of significant wildlife–human conflict in urban areas of Australia, little is known about the patterns of attack by these birds. Such information is essential for the development of sound management plans for this species. We examined the attack behaviour of 48 aggressive magpies from Brisbane during September–October 1999, paying particular attention to the types of intruders targeted. All attacking birds were male. A clear majority (71%) of birds attacked only one intruder type, with about half attacking pedestrians only similar proportions targeted cyclists (8%) only and mail deliverers (10%) only. While all intruding cyclists and mail deliverers were attacked, magpies did not attack all pedestrian intruders, suggesting possible discrimination within this category. Management implications for these intruder types are discussed.

Abstract: Many montane avian communities are likely to be impacted negatively by future climate change. The ability to monitor these ecosystems effectively is therefore a priority. As species are expected to track their preferred climates by moving upwards in elevation, using indicator species of elevations has been suggested as a climate change monitoring strategy and has been explored for a variety of taxa in eastern Australia. Birds have great potential as vertebrate indicators due to their familiarity, detectability, and well known life histories. We used automated recording units (ARUs) and point counts to s le the avifauna along two elevational gradients in subtropical rainforest in north-eastern New South Wales, Australia. We used the indicator value protocol to identify avian indicators of elevation suitable for long-term monitoring. Pairs of species were more reliable than single species as indicators, and searching for indicators of elevational ranges (e.g. 300–500m) proved more effective than looking for indicators of single elevations (e.g. 300m). Point counts and ARUs were equally effective at determining indicators of elevations and ARUs performed particularly well in spring. We present avian indicator sets of lowland and highland sites, which provide a baseline for future monitoring of the effects of climate change on the region’s avifauna. The methodology employed here is broadly suitable for similar studies elsewhere. We propose that the use of ARUs to identify indicator species of elevations is an effective strategy for monitoring the effects of climate change on montane avian communities worldwide.

Abstract: Accurate data on presence/absence and spatial distribution for fauna species is key to their conservation. Collecting such data, however, can be time consuming, laborious and costly, in particular for fauna species characterised by low densities, large home ranges, cryptic or elusive behaviour. For such species, including koalas ( Phascolarctos cinereus ), indicators of species presence can be a useful shortcut: faecal pellets (scats), for instance, are widely used. Scat surveys are not without their difficulties and often contain a high false negative rate. We used experimental and field-based trials to investigate the accuracy and efficiency of the first dog specifically trained for koala scats. The detection dog consistently out-performed human-only teams. Off-leash, the dog detection rate was 100%. The dog was also 19 times more efficient than current scat survey methods and 153% more accurate (the dog found koala scats where the human-only team did not). This clearly demonstrates that the use of detection dogs decreases false negatives and survey time, thus allowing for a significant improvement in the quality and quantity of data collection. Given these unequivocal results, we argue that to improve koala conservation, detection dog surveys for koala scats could in the future replace human-only teams.

Abstract: Sexual coercion by males is generally understood to have three forms: forced copulation, harassment and intimidation. We studied Australian brush-turkeys, Alectura lathami, to determine whether some male behaviours towards females at incubation mounds could be classified as aggressive, whether males were attempting sexual coercion and, if so, whether the coercion was successful. We found that some male behaviours towards females were significantly more likely to be followed by the cessation of female mound activity, and hence could be classified as aggressive, while others were significantly more likely to be followed by the commencement of female mound activity, and hence could be classified as enticing. Copulation was preceded by higher rates of male enticement and by higher rates of certain types of male aggression. It therefore seemed that males were attempting sexual coercion. There was little evidence, however, that this combination of coercion and enticement was successful in obtaining copulations. While forced copulation did occur, it was infrequent, and no evidence could be found for intimidation. We conclude that harassment is the primary form of sexual coercion by male brush-turkeys. Although sexual coercion is understood to be a sub-optimal tactic, brush-turkey sexual coercion was employed as a primary tactic by dominant males who owned incubation mounds. One possible explanation for this apparent paradox is that aggression is the default solution for social conflicts in this species, and hence can be interpreted as a behavioural syndrome.

Abstract: The global extent of supplementary bird feeding is unknown but has consequences for bird conservation and human well-being. Using a measure of search intensity for words related to bird feeding from Google, we document a surge of interest in bird feeding that occurred around the world after Covid-19 led to lockdowns where people stayed home: 115 countries saw an increase in bird feeding search interest. We test whether the existence of interest in bird feeding is associated with greater species richness of bird species, our proxy for bio ersity, and find the relationship is highly significant. Covid-19 lockdowns may have persistent influences on global bird populations and humans’ connection to nature.

Abstract: The aim of this study was to examine the values and attitudes held by Australasian wildlife managers as they relate to wildlife management issues, and to gain some insight into possible future directions and priorities for Australasian wildlife management. During December 2002 – February 2003, 138 questionnaires were completed by members of the Australasian Wildlife Management Society (AWMS) and registrants of the 2002 AWMS annual conference. Threatened species management, threatened communities/habitats, and management of introduced species were the issues rated as needing the highest priority for the Australasian Wildlife Management Society. Issues such as animal rights, genetically modified organisms and timber harvesting on public lands were the lowest-rating issues. Respondents expressed a strong belief in managing and controlling wildlife to achieve wildlife management objectives, a strong belief that wildlife should be protected and that wildlife managers should minimise the pain and suffering of in idual animals, and a belief that resources should be directed towards conserving wildlife populations rather than protecting in idual animals from non-threatened populations. While respondents held a strong belief that it is important to consult the community when developing wildlife management policies and programs, there was little support for a comanagerial approach where the community has a significant role to play in decision-making processes.

Abstract: The piezoceramic 0.96(K0.5Na0.5)0.95Li0.05Nb0.93Sb0.07O3−0.04BaZrO3 (KNLNS0.07-BZ), which shows large piezoelectric response (d33 ≈ 425 pC/N), has been considered as one of the promising Pb-free substitutions for Pb(Zr,Ti)O3. In this paper, we investigate the phase transition sequence for KNLNS0.07-BZ by employing the dielectric measurement, mechanical spectroscopy, as well as Raman spectroscopy. Two ferroelectric-ferroelectric transitions have been detected by inspecting anomalies in the spectra, indicating the existence of three ferroelectric phases. Moreover, in-situ X-ray diffraction study has been further performed on KNLNS0.07-BZ to identify the crystal structure for each phase. The result reveals that the phase sequence for KNLNS0.07-BZ evolves from tetragonal (T) to rhombohedral (R) via an intermediate orthorhombic (O) phase. And the piezoelectric-optimal region for KNLNS0.07-BZ locates on a T-O boundary rather than the previously reported T-R boundary. Strong piezoelectricity may stem from the easier polarization rotation on the T-O boundary with reduced polarization anisotropy.

Abstract: Roads can have significant negative impacts on wildlife. Fauna-sensitive road design (FSRD) can alleviate adverse impacts on several species by installing specialised structures, such as wildlife crossing structures. This developing subfield has generally, however, had a limited impact on transportation planning and management. Indeed, most research is focused narrowly on technological solutions, instead of broader policy learnings. This systematic quantitative literature review (SQLR) of international literature sought to identify the bio ersity concerns acknowledged in transport planning policy, as well as the barriers to the adoption of environmental policies within transport planning. Despite considerable literature available on the impacts of roads on wildlife elsewhere, acknowledgement and consideration of both fauna movement and fauna-sensitive road design were limited in road transportation planning research. More broadly, failure to achieve environmental objectives within transport planning occurred primarily as a result of competing sector interests (conflicted knowledge), different political objectives (political interest), and incorrect interpretation of policies. In essence, the results add new layers of understanding to the field of transportation planning and policy, in particular, the gaps in acknowledgement of wildlife movements and the limitations of current fauna-sensitive road design considered. Importantly, the review identified multiple ecological support tools available to transport policy- and decision-makers. Integration of these in road transportation projects could facilitate enhanced uptake and adoption of FSRD measures and thus foster improved sustainability of the transport network.

Abstract: 1. The formation of large communal roosts is a conspicuous phenomenon associated with a wide range of bird species successfully exploiting urban environments. In many Australian cities, the abundance of the Rainbow Lorikeet ( Trichoglossus haematodus ), a native parrot, has increased markedly in recent decades, with the species roosting in very large numbers within suburban sites. These roosting locations are noisy and cause significant fouling of the land beneath, resulting in conflict with humans. 2. We investigated the selection of roosting sites in this species in Brisbane, Australia, by comparing characteristics of both the general sites of these roosts as well as in idual trees used within roosting sites and trees that were avoided. 3. Lorikeets used a wide variety of tree types for roosting but demonstrated a clear preference for clumped trees within sparsely treed areas that received significantly more artificial light at night than otherwise suitable sites and trees nearby. 4. These features of roosting sites may enhance the detection of nocturnal predators by Rainbow Lorikeets, suggesting a potential positive impact of anthropogenic lighting. Our findings provide valuable insights into the management of roost-related conflicts in urban areas. We encourage further investigations into the possible benefits of artificial light.

Abstract: Wild predators that attack people represent a significant challenge to the management authorities charged with conserving populations whilst minimising human safety risk. Fraser Island is home to an iconic population of dingoes (Canis dingo). However, conflict stemming from negative human–dingo interactions (incidents), some resulting in serious human injury and in one case, a fatality, is an ongoing concern. In an effort to highlight important factors influencing incident dynamics, we investigated the most serious incident reports gathered by the Queensland Parks and Wildlife Service for the period 2001–15. We found a consistent pattern of incidents peaking in March/April and also July, corresponding with dingo breeding and whelping seasons (respectively). Monthly vehicle permit numbers (a proxy for visitation) were not positively correlated with incident rates, except during the breeding season. Male dingoes, particularly subadult males, featured heavily in incidents. Despite the fatality being highly publicised and the advent of copious on-site warning messages and other management interventions, serious incidents continue to occur annually, including some involving children. This suggests that risks are either not always understood, or are otherwise being ignored. While our results demonstrate that dingoes generally pose minimal risk to humans, some risk remains, particularly where poorly supervised children are concerned.
