Abstract: Abstract.Diphacinone and chlorophacinone, first-generation anticoagulant rodenticides, are frequently used for control of California ground squirrels (Spermophilus beecheyi) in agricultural and rangeland areas in California, USA. Owing to growing concerns over the risks to non-target species associated with the use of these rodenticides, the USA Environmental Protection Agency (EPA) proposed that the concentration of baits for above-ground use should be reduced from 0.01% to 0.005% active ingredient. We conducted field trials to compare the efficacy of 0.005% and 0.01% chlorophacinone and diphacinone baits in broadcast and spot applications for control of California ground squirrels on rangeland. We found no significant difference in efficacy owing to bait type, concentration or application method. Repeat testing is needed in other habitat types (e.g. crop areas) where alternative foods might reduce the effectiveness of a 0.005% bait application.

Abstract: Autonomously triggered cameras are a common wildlife survey technique. The use of attractants and surrounding microhabitats is likely to influence detection probabilities and survey outcomes however, few studies consider these factors. We compared three attractants (peanut butter‐based, tuna‐based and a control) in a Latin square design through a coastal shrubland with high microhabitat variability at Cape Otway, Victoria, Australia (38º50ʹS, 143º30ʹE). Deployments involved 36 cameras for four days in each of five years. The percentage cover of each vegetation structural type (low [no or sparse cover], moderate [grass] or high [shrubs]) within 20 m of each camera was calculated and reduced to a single variable using PCA. Dynamic occupancy modelling, with lure type and vegetation structure as covariates of detection probability, found that peanut butter attracted the greatest ersity of species (24 of 35 species, 69%) and yielded the greatest number of detections (50% of 319) when compared with tuna oil (66% and 24%, respectively) and the control (43% and 26%, respectively). Peanut butter attracted more Macropodidae (wallabies) and Muridae (rats and mice) however, vegetation structural variables were the greatest influence on Corvidae/Artamidae (raven/currawong) detections with higher detectability in more open areas. Vegetation structure also influenced Muridae detections. This study reinforces the critical choice of appropriate attractants and camera placement when investigating vertebrate groups and highlights the role of microhabitat in the detection of small mammals and birds. We suggest future large‐scale camera surveys consider different bait types and microhabitats in their designs, to control for any biases and enable future advice on ‘optimal’ methods.

Abstract: At the continental scale, ecological research effort is not spatially uniform. We used a century-long bibliometric database of the journal Emu – Austral Ornithology to index the spatial patterns in bird research in Australia (from articles with explicit study locations). Studies have been concentrated in Tasmania and the southwest, southeast and coastal parts of the mainland. Large spatial gaps exist in ornithological study, which are similar to those identified by Arnold Robert McGill in his 1948 review paper ( McGill 1948 ). Pre-1948 only 9.4% of articles [n = 2,107] fell within the gaps mapped by McGill in 1948, indicating that his mapping was largely accurate. These gaps have largely persisted only 11.2% of the 1,498 articles published since 1948 came from within those gaps. We present a complementary spatial gap analysis, which focuses on studies of areas with broadly similar biogeographies (Interim Biogeographical Regions of Australia (IBRAs)). Of 85 mainland IBRAs (of 89 defined), five have no bird studies from within them (368,380 km 2 4.9% of Australia), and 34 have less than 10 studies (3,335,498 km 2 43.9%). We intersect IBRAs with McGill's gaps and show that some IBRAs within McGill's gaps are now better-studied, but 64.8% of the area within the McGill gaps boundaries comprises IBRAs where there have been no post-1948 studies in Emu. We also present an updated map of key geographical gaps in the study of Australian birds, which apparently remain extensive 60 years after they were first identified.

Abstract: Abstract Context At some sites in southern Victoria, browsing pressure caused by high-density koala populations can result in defoliation of preferred browse trees. In extreme cases, this over-browsing can lead to widespread tree death and starvation of koalas. To reduce the potential for mortality of trees and koalas, a management strategy that includes fertility control of females and translocation of healthy in iduals (male and female) has been adopted. AimsTo compare the short- to medium-term survival and body condition of koalas translocated from over-browsed habitat and released into unoccupied (or nearly so) habitat with that of koalas left in situ in compromised habitat. Methods We monitored survival and body condition of 36 translocated koalas for 4–5 months after translocation relative to that of a control group (24 animals) left in situ. Koalas were recaptured and body condition measured (as a scaled body-mass index) ~40 and 137 days after translocation. Additionally, GPS loggers were used to investigate patterns of koala movement. Key resultsSurvival rates of translocated koalas were not different from those of controls and females in both groups showed slightly higher survival rates than did males. After 137 days, control animals had lower scaled body mass, whereas translocated animals, after an initial reduction, had mostly regained, or increased their scaled body mass. Translocated females regained their original scaled body mass faster than did translocated males. Male koalas in both control and translocated groups had higher rates of movement than did females, and translocated koalas had slightly higher rates of movement than did control koalas. Translocated koalas moved farther from their release location than control koalas. ConclusionsOn the basis of the scaled body-mass index, translocated koalas fared better than those left in situ in compromised habitat, even though the density of koalas in the over-browsed habitat had been reduced by a wider salvage translocation program. The process used to identify potential release sites, including a spatial koala-habitat index, accurately predicted suitable koala habitat. ImplicationsThe current management strategy of translocating koalas out of over-browsed habitat is supported and could be more widely applied.

Abstract: Context Loss of eggs to predators is a major cause of reproductive failure among birds. It is especially pronounced among ground-nesting birds because their eggs are accessible to a wide range of predators. Few studies document the main causes of clutch fate of ground-nesting birds. Aims The main objective of the present study was to identify the major egg predator of red-capped plovers (Charadrius ruficapillus). We also investigated the effectiveness of the following two primary strategies available to the plovers to avoid egg predation: (1) the placement of clutches under vegetative cover and (2) avoiding predators by nesting outside the peak season of predator occurrence. Methods Remote-sensing cameras were deployed on plover nests to identify egg predators and nests were monitored over four breeding seasons to document reproductive success and fate. An experiment using false clutches with model eggs investigated the influence of nest cover on the risk of egg predation throughout the year. Line-transect surveys were conducted to estimate the abundance of egg predators in and around the wetlands. Key results The little raven (Corvus mellori) was the major egg predator identified in 78.6% of red-capped plover clutches and in 92.4% of false clutches that were camera-monitored. The hatching success of plover eggs was not influenced by nest cover (P = 0.36), but model egg survival in false clutches improved significantly with the presence of nest cover (P = 0.02). The abundance of little ravens increased during the plover breeding season and was highly negatively correlated with false clutch survival (rpearson = –0.768, P = 0.005). Conclusions Little ravens were the major predator of red-capped plover eggs and their abundance increased significantly during the plover breeding season. Any influence of nest cover on hatching success of eggs may have been masked by the extremely high rate of egg loss associated with the increased little raven abundance during the plover breeding season. Implications The high rate of egg predation is likely to have negative consequences on the local red-capped plover population, suggesting management is warranted. Little raven populations have expanded and, thus, their impact as egg predators needs to be investigated especially on threatened species.

Abstract: Conservation of small mammal species relies on an understanding of their habitat use. We used trapping surveys and telemetry to examine habitat selection and use by the broad-toothed rat (Mastacomys fuscus mordicus) and the bush rat (Rattus fuscipes) in an alpine resort in Victoria. M. fuscus occurred at low numbers, nesting in subalpine wet heathland and foraging in that habitat as well as small patches of disturbed woodland. In contrast, R. fuscipes was more common and nested in woodlands. Although foraging primarily in woodlands, R. fuscipes also foraged in all other available habitats. Both species showed strong selection for woodland fragments within ski runs. Although highly disturbed, these habitats may provide important habitat and connectivity between less disturbed and larger habitat patches.

Abstract: Context In peri-urban environments, high availability of anthropogenic resources may result in relatively high abundances of some species, with potentially negative implications for other native biota. Effective management of such impacts requires understanding of the spatial ecology of problem species. However, home range and habitat use have not been described for the little raven (Corvus mellori), a superabundant native predator that occurs in urban and natural habitats, including those where threatened shorebirds breed. Aims The aim of this study was to provide basic information on little raven home range, habitat use and movements in a coastal peri-urban landscape. Methods Between October 2011 and January 2012 we radio-tracked 20 little ravens captured in a coastal wetland (near Melbourne, Australia). Key results Little ravens were highly mobile, moving up to 9.9 km in an hour (median = 2 km), and had large ranges: Minimum Convex Polygons were 1664–9989 ha (median = 3362 ha). Although most birds used both anthropogenic and natural habitats, some birds strongly selected for coastal wetland habitat. Birds used multiple roosts during the study period, most of which occurred in grassland (58.7%) or urban (22.3%) areas. Movement of up to 8.3 km (median = 2.2 km) between roosts during the night was also detected. Conclusions Ravens were highly mobile and used large home ranges and a variety of habitats, with habitat preferences varying between birds. Implications Considering the large home ranges and inter-in idual variation in habitat preferences of little raven populations, localised management to reduce their impacts on breeding shorebirds is unlikely to be successful.

Abstract: Passive acoustic monitoring (PAM) is increasingly being used for the survey of vocalising wildlife species that are otherwise cryptic and difficult to survey. Our study aimed to develop PAM guidelines for detecting the Yellow-bellied Glider, a highly vocal arboreal marsupial that occurs in native Eucalyptus forests in eastern and south-eastern Australia. To achieve this, we considered the influence of background noise, weather conditions, lunar illumination, time since sunset and season on the probability of detecting vocalisations. We deployed Autonomous Recording Units (ARUs) at 43 sites in the Central Highlands of Victoria during two periods: spring/summer (October 2018 to January 2019), and autumn/winter (May to August 2019). ARUs were programmed to record for 11 hours from sunset for 14 consecutive days during each period. Background noise resulted from inclement weather (wind and rain) and masked vocalisations in spectrograms of the recordings, thus having the greatest influence on detection probability. Vocalisations were most common in the four hours after sunset. Rainfall negatively influenced detection probability, especially during the autumn/winter s ling period. Detection of Yellow-bellied Gliders with PAM requires deploying ARUs programmed to record for four hours after sunset, for a minimum of six nights with minimal inclement weather (light or no wind or rain). The survey period should be extended to 12 nights when rain or wind are forecast. Because PAM is less labour intensive than active surveys (i.e., spotlighting and call playbacks with multiple observers and several nights’ survey per site), its use will facilitate broad-scale surveys for Yellow-bellied Gliders.

Abstract: Capture of wildlife is essential both for research and management, and minimising the amount of stress an animal experiences during capture is important. We examined the behavioural response of koalas to cage traps to improve protocols for trapping koalas. We used heat- and motion-sensing cameras to record the behaviour of koalas in traps, and the duration spent in traps. Behavioural responses were scored on a scale of 0 (no apparent response) to 3 (heightened response) from videos. We successfully trapped a koala in 19 of 21 attempts. For 12 occasions when traps were monitored with cameras, koalas spent 6.3–181.2min in traps and 8 of 12 koalas displayed heightened behavioural responses (score of ≥2). The frequency of response scores did not vary between males and females and was not influenced by trapped duration. We found that traps were effective for capturing koalas however, to minimise overt behavioural responses by trapped koalas, trap-check intervals need to be as short as possible. We recommend the use of trap-trigger devices to alert personnel when a koala is trapped. The addition of such devices in trapping practices may reduce potential for adverse behavioural responses and improve the cost-efficacy of trapping.

Abstract: A species’ social structure influences its patterns of gene flow and disease transmission. Knowledge of social structure therefore is critical for understanding conservation challenges and informing management strategies. We examined the social structure of 33 free-ranging koalas (Phascolarctos cinereus) in a high-density population (6.7 koalas per hectare) during the early and peak phase of the breeding period (August–December) at Cape Otway, Victoria. We used GPS and proximity loggers to quantify koala space use and interactions, and direct observations to determine behaviours associated with interactions. Our proximity loggers recorded 661 interactions (64% male–female, 28% male–male and 8% female–female). A peak in male–male interactions at the onset of the breeding period suggested that males may physically compete for mates at this time. Male–female interactions increased from the onset of the breeding period, and were mostly of short duration (median duration 5.5 min). From field observations of interactions, and the absence of pouch young in December, many of these interactions may have been unsuccessful copulation attempts. Space use and social network analyses revealed that most males had strong links (total interaction duration & min) with only one or two females, despite their spatial overlap and interactions with multiple females. Body mass did not influence a male’s mating success in terms of number of female mates. Our results contrast with those of a lower-density population in central eastern Queensland, suggesting that some aspects of koala social structure may be plastic relative to population density.

Abstract: Woodland birds are declining throughout the agricultural landscapes of south-eastern Australia, but the specific mechanisms driving these declines remain unclear. Reproductive failure via clutch depredation could conceivably contribute to these declines. Although site-scale habitat may influence the risk of clutch failure, larger-scale influences, such as whether a landscape contains a rural town or not (‘landscape type’), may also play a role. This study monitored artificial open-cup nests deployed in three pairs of the two landscape types and: 1) indexed clutch survival and predator assemblage and 2) determined if clutch survival was influenced by landscape type and/or local habitat characteristics. High levels of clutch depredation were observed in both landscape types and for all landscapes, with no evidence to suggest that landscape type or habitat characteristics influenced clutch survival or the time-to-first-predator visit. Predator assemblage also was consistent between landscape types. Generalist avian predators were the most common egg predators. Such egg predators may be ubiquitous throughout the fragmented Box-Ironbark woodlands of south-eastern Australia.

Abstract: Critically Endangered Puerto Rican parrots Amazona vittata are one of the rarest birds in the world. Several exotic mammal species capable of preying on Puerto Rican parrots cohabit the Caribbean National Forest with the only wild population of these parrots. We used tracking plates, monitoring blocks and trapping to index black rats, small Indian mongooses and feral cats in parrot habitat and in public-use areas in the same habitat type. We had high trap success for black rats at all sites (42% of all sites combined), among the highest reported in the world. Rat response to monitoring (nontoxic bait) blocks was universally high, regardless of ground or tree placement. Mongooses were present at all sites, with a greater proportion of plates tracked within the forest than at public-use sites. Cats were present at all forest sites and one of the public-use sites. Presence of the three species did not appear to be linked to human disturbance. Because only 30–40 Puerto Rican parrots survive in the wild, with as few as three pairs nesting in 2002, we concluded that the abundance and pervasiveness of exotic mammalian predators poses a greater threat to the parrots than has been generally acknowledged. This is evidenced by mammalian predation during recent parrot breeding seasons, including six fledglings taken by mongooses and one nest failure from rats during 2000–2003.

Abstract: R. sordidus is a major pest in the sugarcane-growing areas of north Queensland however, little is known about factors affecting populations. This study investigated the effect of a minimum-tillage practice (green-cane harvest and trash-blanketing) compared with the conventional practice (pre-harvest burn and intensive cultivation) on the dynamics of populations of R. sordidus in sugarcane crops of the Herbert River District, N. Queensland, from Nov. 1987 to Sep. 1988 (from planting to harvesting of crops). Populations of R. sordidus became established earlier in trash-blanketed crops, but breeding was reduced as a result of the suppression of summer grasses, identified as a favoured food source of R. sordidus during the breeding period (Jan.-May). Cover of summer grasses was high in conventional areas, and these areas supported populations characterized by a female-biased sex ratio, a high incidence of pregnancy, females in the most productive age-class, and low turnover rates, relative to populations in trash-blanketed areas. Damage to sugarcane increased once breeding had ceased and the diet of R. sordidus had changed from seed and non-cane vegetation to sugarcane. Damage was similar in trash-blanketed and conventional areas, probably as a result of dispersal of in iduals from conventional areas into trash-blanketed areas following the breeding period. Implications for population and damage levels of R. sordidus on a regional scale are discussed.

Abstract: Landscape modification due to urbanisation, agriculture and other human activity can have considerable impact on species’ distributions. Understanding the influence of both site and landscape level characteristics is essential for guiding conservation actions. Our study aimed to determine the influence of site and landscape level characteristics on the distribution of koalas and to identify areas for conservation action in a modified landscape. We used passive acoustic surveys undertaken from October 2019 to January 2020 to determine site occupancy by koalas at 123 sites on the Mornington Peninsula, Victoria, Australia. We extracted variables for each site (within 100 m of recorders) and landscape (within 1 km of recorders) within a GIS. Site variables were tree cover, land use and soundscape, and landscape variables were tree cover, fragmentation, road density, and watercourse length. Site variables did not have an influence on site occupancy by koalas. Landscape-scale tree cover positively influenced, and road density negatively influenced site occupancy. We used our model to predict site occupancy in one-hectare grid cells across the landscape and found that public land was three times as likely as land under private tenure to have high probability of koala presence. Based on our results, increasing tree cover in landscapes where there already is 30% to 68% tree cover and a sealed road density of 1 m per hectare would have the greatest benefit for koalas. Approximately 85 km 2 (11%) of the Mornington Peninsula meets these criteria, with 87% of that land under private tenure. Landscape context is of primary importance for conservation of koalas in a modified landscape. Modelling should be used to improve the effectiveness of conservation actions.

Abstract: Accurate density estimates of rodents are frequently difficult or cost-prohibitive to determine. Thus, a number of techniques (track plates, monitoring blocks, chew cards/sticks, apple slice index, trapping) are often used to index rodent populations. Theoretically, the sensitivity of these indexing techniques could be improved if they applied continuous measurements rather than simple binary measurements (presence/absence). Development of a relative abundance technique that is simple to apply and sensitive to changes in population density is critical for the operational management of rodent pests. In addition to providing a quantitative measure of abundance with statistical parameters, an indexing technique that does not require handling of animals is important in consideration of potential disease issues (for ex le, hantavirus, arenavirus, etc.). We investigated track plates, chew cards and monitoring blocks and associated continuous measurement methods for calculating indices of rodent abundance. In laboratory and field settings, we tested their effectiveness in detecting different population densities of California meadow voles (Microtus californicus). Chew cards were poorly accepted by meadow voles in pen and field tests. However, track plates and monitoring blocks may provide useful tools for indexing meadow vole populations, and have application for other rodent species.

Abstract: The capture of free-ranging in iduals is often needed for research, population management and health assessment. Because of its iconic and threatened species status, methods to capture koalas (Phascolarctos cinereus) receive disproportionate scrutiny. We collated data on koala capture frequency, duration held by noose and incidents from six studies of koalas in Victoria and New South Wales that all used the ‘noose and flag’ method as the primary method of capture. Adverse events occurred in less than 1% of all captures (7 of 1236). Mean capture time in three of four locations recording duration held by noose was less than five minutes, minimising the duration of distress to the koala while allowing researchers to maintain control over the animal. The exception to this was a study in far south-west Victoria where trees were tall and koalas were relatively unresponsive to flagging, resulting in a longer mean duration held by noose (11.2 minutes). The reviewed capture data of the ‘noose and flag’ method suggest that this is an effective and safe capture method, allowing for capture of multiple in iduals in a short period, and suitable for most habitat types and situations.

Abstract: Animal-attached devices have transformed our understanding of vertebrate ecology. To minimize any associated harm, researchers have long advocated that tag masses should not exceed 3% of carrier body mass. However, this ignores tag forces resulting from animal movement. Using data from collar-attached accelerometers on 10 erse free-ranging terrestrial species from koalas to cheetahs, we detail a tag-based acceleration method to clarify acceptable tag mass limits. We quantify animal athleticism in terms of fractions of animal movement time devoted to different collar-recorded accelerations and convert those accelerations to forces (acceleration × tag mass) to allow derivation of any defined force limits for specified fractions of any animal's active time. Specifying that tags should exert forces that are less than 3% of the gravitational force exerted on the animal's body for 95% of the time led to corrected tag masses that should constitute between 1.6% and 2.98% of carrier mass, depending on athleticism. Strikingly, in four carnivore species encompassing two orders of magnitude in mass ( ca 2–200 kg), forces exerted by ‘3%' tags were equivalent to 4–19% of carrier body mass during moving, with a maximum of 54% in a hunting cheetah. This fundamentally changes how acceptable tag mass limits should be determined by ethics bodies, irrespective of the force and time limits specified.

Abstract: Identifying threats and their regional occurrence across a species’ range is increasingly valuable for prioritising threat-specific interventions and achieving effective conservation outcomes. We surveyed registered wildlife rehabilitators to identify (i) threats faced by the koala across Victoria and (ii) their perceptions on koala population trends and potential threat mitigation actions. Wildlife rehabilitators identified habitat loss, fragmentation, and degradation as the biggest threat to koalas, while vehicle collisions, heatwaves and wildfire were also identified as key threats. Accordingly, reducing the clearing of native vegetation was considered the most effective threat mitigation action, while creating of wildlife corridors, planting of more food trees, and educating communities living in koala occupied areas were also considered appropriate mitigation strategies. Finally, 89% of wildlife rehabilitators believed that koala numbers are declining in their region.

Abstract: The effect was determined of a single dose of 2 mg kg-1 diphacinone on three blood-clotting parameters [Prothrombin Time (PT), Partial Thromboplastin Time (PTT), and Protein Induced by Vitamin K Absence or Antagonists (PIVKA)] over a 120-h period in California ground squirrels, Spermophilus beecheyi. Diphacinone resulted in elevated PT, PTT and PIVKA within 24 h of squirrels receiving the dose. The most significant change was observed 72 h after dosing. As time following diphacinone dosing increased, there was higher in idual variation in blood-clotting time. We suggest that increasing the interval between field bait applications should still result in squirrel mortality but reduce the potential for secondary hazards that may occur when squirrels have the opportunity to consume more than one lethal dose of diphacinone.
