Abstract: Feral cats (Felis catus) have a wide global distribution and cause significant damage to native fauna. Reducing their impacts requires an understanding of how they use habitat and which parts of the landscape should be the focus of management. We reviewed 27 experimental and observational studies conducted around the world over the last 35 years that aimed to examine habitat use by feral and unowned cats. Our aims were to: (1) summarise the current body of literature on habitat use by feral and unowned cats in the context of applicable ecological theory (i.e. habitat selection, foraging theory) (2) develop testable hypotheses to help fill important knowledge gaps in the current body of knowledge on this topic and (3) build a conceptual framework that will guide the activities of researchers and managers in reducing feral cat impacts. We found that feral cats exploit a erse range of habitats including arid deserts, shrublands and grasslands, fragmented agricultural landscapes, urban areas, glacial valleys, equatorial to sub-Antarctic islands and a range of forest and woodland types. Factors invoked to explain habitat use by cats included prey availability, predation/competition, shelter availability and human resource subsidies, but the strength of evidence used to support these assertions was low, with most studies being observational or correlative. We therefore provide a list of key directions that will assist conservation managers and researchers in better understanding and ameliorating the impact of feral cats at a scale appropriate for useful management and research. Future studies will benefit from employing an experimental approach and collecting data on the relative abundance and activity of prey and other predators. This might include landscape-scale experiments where the densities of predators, prey or competitors are manipulated and then the response in cat habitat use is measured. Effective management of feral cat populations could target high-use areas, such as linear features and structurally complex habitat. Since our review shows often- ergent outcomes in the use of the same habitat components and vegetation types worldwide, local knowledge and active monitoring of management actions is essential when deciding on control programs.

Abstract: It has been increasingly popular to use natural history specimens to examine environmental changes. As the current functionality of museum specimens has extended beyond their traditional taxonomic role, there has been a renewed focus on the completeness of biological collections to provide data for current and future research. We used the collections of the Western Australian Museum to answer questions about the change in occurrence of five common reptile species due to the rapid urbanization of Perth. We recorded a significant decline in collection effort from the year 2000 onwards (F = 7.65, p 0.01) compared to the period 1990–1999. Spatial analysis revealed that only 0.5% of our study region was well s led, 8.5% were moderately s led and the majority of the regions (91%) were poorly s led. By analysing the trend of specimen acquisition from 1950 to 2010, we discovered a significant inconsistency in specimen s ling effort for 13 common reptile species across time and space. A large proportion of past specimens lacked information including the place and time of collection. An increase in investment to museums and an increase in geographically and temporally systematic collecting is advocated to ensure that collections can answer questions about environmental change.

Abstract: Fire plays a strong role in structuring fauna communities and the habitat available to them in fire-prone regions. Human-mediated increases in fire frequency and intensity threaten many animal species and understanding how these species respond to fire history and its associated effect on vegetation is essential to effective bio ersity management. We used a shrubland mammal and reptile community in semiarid south-western Australia as a model to investigate interactions between fire history, habitat structure and fauna habitat use. Of the 15 species analysed, five were most abundant in recently burnt habitat (8–13 years since last fire), four were most abundant in long unburnt areas (25–50 years) and six showed no response to fire history. Fauna responses to fire history were ergent both within and across taxonomic groups. Fire management that homogenises large areas of habitat through either fire exclusion or frequent burning may threaten species due to these erse requirements, so careful management of fire may be needed to maximise habitat suitability across the landscape. When establishing fire management plans, we recommend that land managers exercise caution in adopting species-specific information from different locations and broad vegetation types. Information on animal responses to fire is best gained through experimental and adaptive management approaches at the local level.

Abstract: Animal conservation requires a sound understanding of movement ecology and habitat selection. A key component of this is identifying habitats that animals actively seek or avoid. We quantified habitat selection and investigated the drivers of variability in the short-term activity area of a small, endangered mesopredator, the northern quoll (Dasyurus hallucatus), in the Pilbara region of Western Australia. We collated, standardised, and analysed 14 northern quoll GPS tracking events from four studies conducted between 2014 and 2018. Northern quolls selected activity areas in locations that were more topographically rugged than the broader landscape, characterised by a higher percentage cover of rocky habitat and riverbed, and a lower percentage cover of spinifex sandplain. The size of their activity area also increased with higher percentage cover of non-preferred spinifex sandplain. Therefore, the destruction of habitats preferred by northern quolls – such as mining of rocky habitat – and introduction of structurally simple habitat like spinifex sandplain, is likely to negatively impact resource availability and lead to altered movement patterns that could decrease survival. Future conservation planning should place emphasis on the protection of rugged rocky habitat for northern quolls, as well as efficient movement pathways between patches of this critical habitat.

Abstract: Context Resource subsidisation as a result of urbanisation and other human activity can have positive impacts for some opportunistic predators. Many species of corvid have benefitted from the expansion of human-dominated habitats however, their impacts on co-occurring prey fauna are generally poorly understood. Aims We aimed to test the hypothesis that urbanisation associated with tourism impacts the predator–prey relationship between Australian ravens, or wardongs (Corvus coronoides), a ubiquitous corvid of southern Australia, and Rottnest Island bobtails (Tiliqua rugosa konowi), a subspecies of bobtail lizard isolated to a small (19km2) island off the coast of Western Australia. Methods Using clay model lizards and camera traps, we assessed the wardongs’ attack rates by distance from the settlement and by whether the model was in closed or open habitat. Key Results We found that while wardongs preyed upon Rottnest Island bobtails, predation was not affected by proximity to human settlement despite the highest number of wardongs being found there. Models in closed vegetation were attacked by wardong significantly more than were those in open vegetation. Implications Increased predation rates in closed vegetation suggests that current revegetation efforts on the island may be increasing the availability of preferred hunting habitat for the wardong. This finding may influence decisions by management on whether to control the large population of wardongs on the island.

Abstract: Populations in fragmented urban remnants may be at risk of genetic erosion as a result of reduced gene flow and elevated levels of inbreeding. This may have serious genetic implications for the long-term viability of remnant populations, in addition to the more immediate pressures caused by urbanisation. The population genetic structure of the generalist skink Ctenotus fallens was examined using nine microsatellite markers within and among natural vegetation remnants within a highly fragmented urban matrix in the Perth metropolitan area in Western Australia. These data were compared with s les from a large unfragmented site on the edge of the urban area. Overall, estimates of genetic ersity and inbreeding within all populations were similar and low. Weak genetic differentiation, and a significant association between geographic and genetic distance, suggests historically strong genetic connectivity that decreases with geographic distance. Due to recent fragmentation, and genetic inertia associated with low genetic ersity and large population sizes, it is not possible from these data to infer current genetic connectivity levels. However, the historically high levels of gene flow that our data suggest indicate that a reduction in contemporary connectivity due to fragmentation in C. fallens is likely to result in negative genetic consequences in the longer term.

Abstract: We report on the genetic structuring of populations of a large burrowing frog, Heleioporus albopunctatus, from the central wheatbelt of Western Australia. This region has been highly fragmented by vegetation clearance for agriculture since the early 1900s. Genetic variation at four variable loci in 22 populations was analysed using cellulose acetate electrophoresis. Analysis across all populations showed a moderate, but significant, degree of sub ision (Fst = 0.087 ± 0.049, P 0.05) and high levels of heterozygosity (H = 0.133, s.e. = 0.084). Several small populations had higher Fst values in pair-wise comparisons. A mantel test revealed no significant relationship between genetic distance and geographic distance (r = –0.136, P = 0.34) and this, combined with data from multidimensional scaling analyses, suggests that geographic isolation of populations is not a significant determinant of genetic structuring. Despite this, the presence of high levels of sub ision as a result of the erosion of genetic ersity indicates that regional persistence may be dependent on the maintenance of metapopulation structures that allow gene flow.

Abstract: Prescribed fire is a widespread management practice in fire-prone ecosystems that can have significant effects on fauna. To inform the development of appropriate prescribed burning regimes, we explored bird responses to time since fire in threatened Banksia woodlands in south-western Australia. We used area searches to estimate bird densities on 20 plots ranging from 1 to 26 years post fire. Fire had no significant effect on the overall bird community or any foraging guilds and there was no clear post-fire succession. Of the 26 frequently occurring species analysed, only two showed responses to fire, with yellow-rumped thornbills more abundant in early and late post-fire sites and scarlet robins more abundant in either early, or early and late post-fire habitats. Our study suggested that bird communities in Banksia woodlands are quite adaptable to a range of prescribed burning regimes. However, owing to late-successional reptiles, Carnaby’s black cockatoo and mammals in Banksia woodlands, we recommend prescribed burning regimes that reduce early and increase late successional habitat. Phytophthora dieback, urbanisation and associated habitat fragmentation and a drying climate may have important synergistic effects and the role of these in structuring bird communities needs to be further considered in developing appropriate fire regimes.

Abstract: Invasive predators have decimated island bio ersity worldwide. Rats ( Rattus spp.) are perhaps the greatest conservation threat to island fauna. The ground nesting Palau Micronesian Scrubfowl Megapodius laperouse senex (Megapodiidae) inhabits many of the islands of Palau’s Rock Island Southern Lagoon Conservation Area (RISL) in the western Pacific. These islands are also heavily visited by tourists and support populations of introduced rats, both of which may act as added stressors for the scrubfowl. Using passive chew-tag and call playback surveys on five tourist-visited and five tourist-free islands, we investigated if rats and tourists negatively affect scrubfowl, and if higher rat activity is associated with tourist presence. Rat detection probability and site occupancy were significantly higher on tourist visited (89% and 99%, respectively) compared to tourist-free islands (52% and 73%). Scrubfowl were detected at significantly more stations on tourist-free (93%) than tourist visited (47%) islands and their relative abundance was higher (2.66 and 1.58 birds per station, respectively), although not statistically significantly. While rat occupancy probability likewise had a non-significant negative effect on scrubfowl numbers across islands, our results show a negative relationship between tourist presence and scrubfowl in the RISL. Our findings also suggest that rat populations may be augmented by tourist visitation in the RISL. Although this situation may not seriously affect the scrubfowl, it may be highly detrimental to populations of other threatened island landbirds.

Abstract: Translocations to closed systems such as fenced reserves are commonly used for conservation of threatened fauna species worldwide however, resources are limited in these areas, and natural processes that regulate populations in response to resource availability are unable to occur. This can result in overabundance followed by overuse of resources, potentially resulting in extreme declines or local extinctions. Resource exhaustion can negatively impact other fauna in the closed environment that exploit similar resources, through inter‐specific competition. This paper discusses the reintroduction of Boodie ( Bettongia lesueur ) and Mala ( Lagorchestes hirsutus ) to a fenced reserve on the Matuwa Indigenous Protected Area, Western Australia, and raises the concern of potential competition between the two threatened species.

Abstract: The Pilbara population of the northern quoll (Dasyurus hallucatus) has been seldom studied, and the impacts of threats such as altered fire regimes, total grazing pressure, predation and mining and infrastructure development are not well understood. While the Pilbara was once thought likely to provide refuge for northern quolls from the poisonous cane toad (Rhinella marina), recent modelling suggests that cane toads will invade the region. The environmental approvals process for mining development in the Pilbara has generated considerable offset funds that are to be directed towards research on the northern quoll. In an effort to identify future research priorities for this species in the Pilbara through a collaborative process, the Western Australian Department of Parks and Wildlife hosted a workshop attended by scientists, environmental consultants, mining proponents and state and federal regulators. Participants at the workshop identified five key areas for future research effort: (1) develop appropriate and standardised survey and monitoring methods (2) define areas of critical habitat and better understand how disturbance affects habitat quality (3) improve our understanding of population dynamics (4) better understand the key threats to the northern quoll and the interactions between these threats in the Pilbara and (5) determine whether the northern quoll will colonise restored areas or artificial habitat. We provide the expected timelines and current allocation of resources to these research priorities over the next 10 years. We reflect on the lessons learnt from the workshop process and consider ways to improve the outcomes of such collaborative exercises.

Abstract: Semi-arid landscapes are of interest to fire ecologists because they are generally located in the climatic transition zone between arid lands (where fires tend to be rare due to lack of fuel, but are enhanced following large rainfall episodes) and more mesic regions (where fire activity tends to be enhanced following severe rainfall deficits). Here we report on the characteristics of the contemporary fire regimes operating in a semi-arid region of inland south-western Australia with rainfall averaging around 300 mm per annum. To characterize fire regimes, we analyzed a geodatabase of fire scars (1960–2018) to derive fire preferences for each major vegetation type and fire episode and used known fire intervals to model fire hazard over time and calculate typical fire frequencies. We also used super epoch analysis and correlations to explore relationships between annual fire extent and rainfall received before the fire. We found fires strongly favored sandplain shrublands, and these tended to experience hot crown fires once every 100 years (median fire interval), with fire hazard increasing linearly over time. In contrast, fires were rare in eucalypt woodland and other vegetation types, with a median interval of 870 years and broadly consistent fire hazard over time. Annual fire extent was most strongly linked with high rainfall in the year prior to fire, and this was particularly so for eucalypt woodlands. Large-scale fires in shrublands tended to favor areas burnt in previous large fires, whereas in woodlands they favored edges. In conclusion, we found ergent fire regimes across the major vegetation types of the region. Sandplain shrublands were similar to Mediterranean shrublands in that they experienced intense stand-replacing wildfires which recovered vigorously although slowly, meaning burnt shrublands did not experience fires again for at least 25 and 100 years on average. In contrast, eucalypt woodlands were fire sensitive (trees readily killed by fire) and experienced fires mostly around the edges, spreading into core areas only after large rainfall events elevated fuel levels. Overall, both vegetation types subscribed to typical arid-zone fire regimes where elevated rainfall, and not drought, promoted fires, although the role of fuel accumulation over time was more important in the shrublands.

Abstract: Malformations of vertebrae potentially occur across many taxa, particularly in Testudines, which are susceptible to kyphosis (dorsoventral curvature of the spine). Such malformations may stem from either genetic or environmental origins, and their prevalence and associated impacts on survival remain poorly understood. However, scoliosis (sideways curvature of the spine) is rarely reported and especially so in wild lizards. We report here on the first known case of scoliosis in a wild Australian lizard, the skink Ctenotus fallens , from Perth, Western Australia. This occurrence is the first of 805 in iduals captured in a natural population monitored annually for the past 11 years. Reporting and monitoring of the frequency of such abnormalities may be a useful indicator of environmental change‐induced impacts on populations.

Abstract: Understanding the spatial requirements of a species allows one to tailor actions that can help protect species and their habitats. We investigated the spatial needs of the endangered northern quoll (Dasyurus hallucatus) in the Pilbara. We analysed field data based on GPS-telemetry or a combination of GPS and VHF telemetry for 11 northern quolls with data collected over two week periods. Using MCP and Kernel methods, we found average short-term ranges of 193 ha and 115 ha for males, and for the only female with reliable data the estimates were 34 ha and 23 ha, respectively, with Kernel-based core areas that were between five and three times smaller for males and the female, respectively. We found support for our hypothesis that ranges differ between seasons, but with a seasonal trend that was different from that expected. The ranges of males during the premating/mating season were smaller than during the pouch-young season. Our study provides the first detailed attempt to define and understand short-term movement behaviour of the Pilbara northern quoll. The information derived from our study can help to increase the accuracy of predictive outputs and better inform habitat prioritisation and conservation management of the Pilbara northern quoll population.

Abstract: Characterizing patterns of habitat use is an important first step for effective conservation planning. Species restricted to low‐lying islands are at greatest risk from climate change‐related sea level rise, and requirements for breeding and foraging habitat may determine their risk from tidal inundation. The endangered Micronesian Scrubfowl ( Megapodius laperouse senex ) is a model species for understanding these impacts. This species faces the cumulative challenges of tourist visitation, invasive species, and rising sea levels, yet little is understood about its habitat use in the Rock Islands Southern Lagoon Conservation Area (RISL) of Palau. We studied the habitat requirements of this mound‐nesting scrub‐fowl as a representative of a group of birds considered highly vulnerable to climate change. Analysis of 15 habitat variables at 24 incubation mounds and 26 randomly chosen sites indicated that scrubfowl selected incubation sites that were close to shore, contained large trees, and exhibited greater canopy heights than the surrounding forest. Birds preferentially built mounds at the base of large ironwood trees ( Casuarina equisetifolia ) but selected sites with significantly more breadfruit trees ( Artocarpus mariannensis ) than random. Scrubfowl foraged in a non‐preferential manner, making use of all littoral strand forest habitat. Direct anthropogenic habitat loss is not a major threat to scrub‐fowl in the RISL, but their breeding habitat is highly vulnerable to climate change‐driven sea level rise.

Abstract: The rapid expansion of urban areas worldwide is leading to native habitat loss and ecosystem fragmentation and degradation. Although the study of urbanisation’s impact on bio ersity is gaining increasing interest globally, there is still a disconnect between research recommendations and urbanisation strategies. Expansion of the Perth metropolitan area on the Swan Coastal Plain in south-western Australia, one of the world’s thirty-six bio ersity hotspots, continues to affect the Banksia Woodlands (BWs) ecosystem, a federally listed Threatened Ecological Community (TEC). Here, we utilise the framework of a 1989 review of the state of knowledge of BWs ecology and conservation to examine scientific advances made in understanding the composition, processes and functions of BWs and BWs’ species over the last 30 years. We highlight key advances in our understanding of the ecological function and role of mechanisms in BWs that are critical to the management of this ecosystem. The most encouraging change since 1989 is the integration of research between historically disparate ecological disciplines. We outline remaining ecological knowledge gaps and identify key research priorities to improve conservation efforts for this TEC. We promote a holistic consideration of BWs with our review providing a comprehensive document that researchers, planners and managers may reference. To effectively conserve ecosystems threatened by urban expansion, a range of stakeholders must be involved in the development and implementation of best practices to conserve and maintain both bio ersity and human wellbeing.

Abstract: Invasive rats are the biggest threat to island bio ersity world-wide. Though the ecological impacts of rats on insular biota are well documented, introduced rats present a difficult problem for detection and management. In recent decades, improved approaches have allowed for island-wide eradications of invasive rats on small-medium sized islands and suppression on large islands, although both these still represent a formidable logistical and financial challenge. A key aspect of eradication or suppression and ongoing management is the ability to detect the presence of rats, especially at low densities. Here we review recent developments in the field of rat surveillance and summarise current published literature to recommend practices and the factors to consider when developing a surveillance program for either eradication or suppression plans. Of 51 empirical studies covering 17 countries, 58% were from New Zealand. Although detecting rats at low density is extremely challenging, advances over the past 15 years, have significantly improved our ability to detect rats. Motion-sensored cameras and rodent detection dogs have greatly improved our ability to detect rats at low densities, with cameras consistently showing an ability to detect rats at lower densities than other techniques. Rodent detection dogs are also able to reliably detect even an in idual rat, although there are challenges to their widespread adoption, particularly in developing countries, due to the cost and skills required for their training and maintenance. New monitoring devices, the use of eDNA and drones represent current and future innovations to improve detection.

Abstract: The impacts of anticoagulant rodenticides (ARs) on non-target wildlife have been well documented in Europe and North America. While these studies are informative, patterns of non-target poisoning of wildlife elsewhere in the world may differ substantially from patterns occurring in Australia and other countries outside of cool temperate regions due to differences in the types of ARs used, patterns of use, legislation governing sales, and potential pathways of secondary exposure. Most of these differences suggest that the extent and severity of AR poisoning in wildlife may be greater in Australia than elsewhere in the world. While many anecdotal accounts of rodenticide toxicity were found - especially in conjunction with government control efforts and island eradications - no published studies have directly tested rodenticide exposure in non-target Australian wildlife in a comprehensive manner. The effects of private and agricultural use of rodenticides on wildlife have not been adequately assessed. Synthesis of reviewed literature suggests that anticoagulant rodenticides may pose previously unrecognised threats to wildlife and indigenous people in Australia and other nations with erse and abundant reptile faunas relative to countries with cooler climates where most rodenticide ecotoxicology studies have been conducted. To address the identified knowledge gaps we suggest additional research into the role of reptiles as potential AR vectors, potential novel routes of human exposure, and comprehensive monitoring of rodenticide exposure in Australian wildlife, especially threatened and endangered omnivores and carnivores. Additionally, we recommend regulatory action to harmonise Australian management of ARs with existing and developing global norms.

Abstract: New Britain in the Bismarck Archipelago of Papua New Guinea supports 14 endemic bird species and together with New Ireland, forms an Endemic Bird Area that supports 38 restricted range species. Extensive conversion of lowland forest to oil palm plantations resulted in the loss of over 20% of forest under 100 m altitude between 1989 and 2000. However the rate of loss has subsequently slowed (2.2% loss across all altitudes between 2002 and 2014), and much forest remains at higher altitudes: 72% of New Britain remained forested (including secondary forest) in 2014. Despite the ongoing high threat and rich endemic bird fauna, the state of knowledge of the conservation status of birds in New Britain is very poor. We use an unprecedented dataset based on 415 hours of bird surveys conducted in oil palm plantations, as well as primary and secondary forests at all altitudes, to revise the IUCN status of New Britain’s birds. These data indicate that six species of elevated conservation concern are less dependent on old-growth forest than previously assessed. We recommend reduced population size estimates for one species, New Britain Kingfisher Todir hus albonotatus. We recommend increased population size estimates for seven species: Pied Cuckoo-dove Reinwardtoena browni , Yellowish Imperial Pigeon Ducula subflavescens , Green-fronted Hanging Parrot Loriculus tener , Blue-eyed Cockatoo Cacatua opthalmica , Violaceous Coucal Centropus violaceous , New Britain Boobook Ninox odiosa and New Britain Thrush Zoothera talaseae . Despite our comprehensive surveys, Slaty-backed Goshawk Accipiter luteoschistaceus , New Britain Sparrowhawk Accipiter brachyurus , New Britain Bronzewing Henicophaps foersteri and Golden Masked-owl Tyto aurantia remain very rarely recorded and require further assessment. With ongoing habitat loss, particularly in lowland areas, New Britain’s birds urgently require more attention.
