      Abstract: Laura Ruykys, Nicola Hanrahan, Danielle Stokeld
      Black and white image (taken from video footage) of a ghost bat in flight at night time, approximately 1–2 m above ground, with a reference tree in the background and a fence dropper with reflective tape below.There is currently no standardised survey methodology for the detection of the threatened ghost bat at a landscape scale. In this study, we trialled call playback using the ghost bat’s social vocalisations at pre-determined distances from known roosts and then applied the method across a survey area of 65 010 ha. Our results identified that call playback is a reliable method of surveying for this cryptic species away from the roost in landscape-scale assessments. Still photograph from video camera footage.

      An adult Asian water buffalo (Bubalus bubalis) walking through mud on the edge of a savanna waterhole.Feral ungulate species have high water requirements, yet research about their use of savanna waterholes in northern Australia is lacking. This study demonstrates that feral ungulate species have varied responses to water scarcity, so culling by conservation land managers may be optimised by targeting species under different conditions. Our findings indicate climate change will exacerbate ungulate impacts in water-limited ecosystems. Photograph by Helenna Mihailou.

      Abstract: Eliane D. McCarthy, Jordan O. Hampton, Rob Hunt, Stuart Williams, Grant Eccles, Thomas M. Newsome
      Sambar deer being held on a grassy surface, wearing a blindfold and cut-up pool noodle sections on its antlers for safety. A rectangular foam sheet is positioned vertically over its neck.Deer are expanding in distribution and abundance in Australia, and effective deer capture methods are needed for telemetry studies of these invasive species. We assessed the use of aerial net gunning and chemical immobilisation administered via hand injection to capture and fit GPS collars to sambar deer and red deer in alpine Australia. Limited mortalities were recorded during capture, and no mortalities were recorded for 45 days post-capture. This study describes an effective method for the safe capture of sambar deer and red deer, which will assist future wildlife researchers to further refine helicopter-based capture protocols and to collect information on the spatial ecology of these species.

      Photograph of an Eastern grey squirrel (Sciurus carolinensis)Invasive non-native species are on the rise worldwide, exacerbating wildlife’s already significant environmental and economic impacts. On the basis of the eastern grey squirrel (Sciurus carolinensis) in the UK, we have demonstrated that there is an important balance between the efficacy of different population management approaches and the willingness of landowners to apply them. Recommendations on management strategies must understand and account for this human dimension. Photograph: Plight of the Red Squirrel – APHA Science Blog (©APHA).

      Large fox (side-on view looking at camera) in sandy terrain with scrub in background.Invasive mammalian predators are a global threat to biodiversity, yet evaluating and monitoring management outcomes remains challenging. This study aimed to evaluate the effect of lethal poison baiting on two red fox populations in semi-arid Victoria using activity and density metrics. We found little evidence that baiting reduced fox activity or density, and fox survival was high. We provide the first fox density estimates for the region and suggest that multiple lines of evidence be used to confirm the rigour of index-based metrics.

      Black and white photo of a long-nosed potoroo crouched next to a wooden stake.A comprehensive understanding of movements and space use can underpin the effective management of threatened species, yet this understanding is lacking for many at-risk species. This study aims to describe the movement and ranging behaviour of a nationally threatened, ground-dwelling native Australian mammal, the long-nosed potoroo, using GPS dataloggers for the first time. We found home ranges were larger than expected and make recommendations for how this information may be incorporated into the management of potoroos, particularly in relation to a key threatening process facing this species – inappropriate fire regimes.

      Gulls are frequent predators of tern chicks and eggs, causing managers to look for ways to reduce the impact of gulls on tern reproductive success. This study assessed two common management approaches (shooting/trapping and overhead lines followed by targeted trapping) to assess their efficacy at not only stopping gull nesting within the tern colony, but also preventing gulls from entering the colony area. Our data suggest that overhead lines may present an alternative to lethal control, but numerous factors should be considered when selecting a management approach. Photograph by Peter McGowan.

      Although necessary for research, animal capture may lead to mortality, which is often only assessed after data collection. We identified potential causes of post-capture mortality in wild turkeys and adjusted our protocols to lower mortality risk. We recommend that when possible, investigators assess protocols throughout their study and adapt accordingly to limit negative repercussions of capture and handling. Photograph by Erik Blomberg.

      Abstract: Naomi E. Davis, David M. Forsyth, Andrew J. Bengsen

      We evaluated the extent to which a high-density non-native fallow deer population (37 deer per km2) competed with livestock for food during a severe drought in eastern Australia. Fallow deer reduced stocking densities in natural pasture by 50.2%. It is likely that browsing, including on Eucalyptus, helped fallow deer to persist at high densities during the severe drought of 2018. Photograph by D. M. Forsyth.

      Abstract: R. E. L. Simpson, D. G. Nimmo, L. J. Wright, S. Wassens, D. R. Michael

      Habitat loss and fragmentation are leading causes of biodiversity decline, yet the influence on Australian semi-arid reptiles is poorly known. The aim of this study was to investigate factors influencing the distribution and occurrence of habitat specialist and generalist reptile species in an agricultural landscape subject to habitat loss and fragmentation. Specialists were most sensitive to habitat loss and fragmentation and were less likely to persist in small patches of remnant vegetation within the agricultural matrix. Retaining representative parcels of land within agricultural landscapes and setting aside in-perpetuity conservation reserves on private property are required to protect reptile communities in semi-arid, production environments.

      Abstract: A. K. Delsink, J. J. van Altena, M. L. Schulman, H. J. Bertschinger

      Lethal control has largely been synonymous with South African elephant management. As an alternative, porcine zona pellucida immunocontraception was introduced as a novel, non-lethal elephant population control method and is currently adopted in 43 South African reserves. Current policy recommends culling as the last resort. New legislation that considers wellbeing and welfare has been promulgated. Elephant management philosophy has evolved, and all population management options, including immunocontraception, must be fully considered in South Africa’s largest national park, the Kruger.

      Abstract: Lee A. Rollins, Daniel Lees, Andrew P. Woolnough, Andrea J. West, Michael Perry, David M. Forsyth

      We investigated within-population genetic diversity and connectivity, and origins of introduced Australian and New Zealand sambar deer. Mitochondrial data indicated that these introduced deer are more similar to those from an identified native-range western clade (South/Central Highlands of India, Sri Lanka), rather than an eastern clade (eastern India, Southeast Asia). Genetic diversity was lower in the introduced range than reported in the native range. There was no evidence of population structure within introduced populations, although each was genetically distinct.

      Abstract: Graeme Coulson, Michelle E. Wilson

      Culling overbundant native wildlife is unpopular, so managers often turn to fertility control as a more appealing alternative. We assessed contraceptive implants in kangaroos and found that they effectively stopped breeding, but it was challenging to implant enough kangaroos so that abundance was reduced. Understanding these practical constraints on fertility control will assist future management programs. Photograph by Graeme Coulson.

      Flatback turtles nest only in Australia, with rookeries being distributed on island and mainland beaches across northern Australia. Their mainland rookeries are exposed to substantial levels of introduced and native predators. Using a combination of daily in-person monitoring and an array of camera traps, we recorded that a quarter of nests were dug into, with up to five re-entries into an individual nest witnessed. The main nest depredator was the red fox (Vulpes vulpes), an introduced species to Australia. Photograph by Joanne King, DBCA.

      Abstract: Caroline Norén Flynn, Átilla Colombo Ferreguetti, Luciana Ardenghi Fusinatto, Marlon Almeida-Santos, Fernanda Dias-Silva, Helena Godoy Bergallo, Carlos Frederico D. Rocha

      Stream-associated species tend to have their occurrence in space overestimated, leading to an underestimation of their extinction risk. We generated occupancy models that account for imperfect detection to describe the occupied microhabitats by Hylodes fredi, an endemic stream-dwelling frog. Occupancy was affected by rock and leaf-litter cover, whereas detectability was affected by leaf litter and air temperature. Our results confirmed that H. fredi is mostly limited to the stream margins, and the need to consider this strict occupancy in conservation decisions of stream-dwelling species.

      Measuring habitat quality for threatened species is a priority in conservation management, but traditional metrics can be costly. As a result, proxies like habitat suitability are used, despite limited research on their relation to actual habitat quality measures like body condition. We demonstrate the utility of habitat suitability models in predicting mean population fitness of northern quolls (Dasyurus hallucatus), an endangered marsupial predator. Photograph by Harry Moore.
